ULTRAHIGH SPEED REVOLVING/ROTATING MEAT SLICER

Technical Field The present invention relates to a belt power transmission type ultrahigh speed revolving/rotating meat slicer. More particularly, the present invention relates to a belt power transmission type ultrahigh speed revolving/rotating meat slicer, which has the following advantages: -The meat slicer uses replaceable circular knife blades such as a respective frozen and chilled meat slicing blade to make raw meat sliced into a thickness of one millimeter or less.

-To enhance a meat slicing efficiency, the revolving/rotating base unit is formed at a predetermined inclined angle. -Meat to be sliced is made to pass through the circular knife blade using a conveyer mechanism of the loading box. Accordingly, an amount of the unnecessarily wasted meat is reduced, and a quality of thickness of the processed meat becomes uniform.

-The meat slicer can perform functions of a segmental cutter and a chop cutter as well as a meat slicing function, in order to play a role of a multi-purpose meat processing machine for processing meat by part or kind thereof.

-A combining relationship between components of the meat slicer is simplified. After separation of the components, a water cleaning is facilitated.

-Since the frozen and chilled meat slicing blade can be automatically operated and replaced under the control of a control panel, the raw, chilled, and frozen meat can be simultaneously cut or sliced at a meat slicing minimum thickness of 0.5mm, a meat slicing maximum speed of 330-360 times per minute, and a meat slicing maximum width of 350mm.

Background Art

A scale of market at the field of meat processing foods has been recently surveyed as miniature stores (meat shops) of about 50,000 in Republic of Korea and about 30,000 in Japan, and meat processing factories and large-scale distribution stores of about 8,000 in Republic of Korea and about 20,000 in Japan, in number of stores . In view of a market share, raw and chilled meat occupies a market share of 30% in Republic of Korea and 70% in Japan, and frozen meat occupies a market share of 70% in Republic of Korea, and 30% in Japan. The number of the domestic meat processing machine manufacturing companies is five or so. They produce and sell frozen meat slicers and chilled meat slicers for miniature stores and frozen meat chop cutters for large-sized stores. Chilled chop cutters and revolving/rotating meat slicers using circular knife blades for frozen meat for use in factories and large-sized stores are totally imported from the Japanese companies, that is, Nantsune and Watanabe. By domesticmarket change, every year, theminiaturemeat stores

decrease and the large-scale distribution stores increase. As a result, a raw and chilled meat dealing rate increases rapidly, and thus meat processing machines imported from Japan occupy the domestic market in Republic of Korea. In general, according to a meat storage temperature, raw meat is kept and distributed at the temperature of +4 ^° C~+10 ^° C, chilled meat is kept and distributed at the temperature of 0 ^° C~+4 ^° C, and frozen meat is kept and distributed at the temperature of 0 ^° C or less. According to a meat feature, the frozen meat is hard like a piece of wood and thus has no nature of sticking to a knife blade during slicing of meat to thereby make it easy to slice meat. The chilled meat and raw meat has a very high possibility of sticking to a knife blade.

Therefore, referring to the following Table containing "Technology comparison between the conventional art and the present invention, " a miniature frozen meat slicer and a chilled meat slicer mount have a circular knife blade mounted in a fixed frame, respectively. Accordingly, a rotational force is given to the circular knife blade at a fixed state where no position is changed, and a meat loading box reciprocates. As a result, the conventional meat slicers slice meat like a plane, and thus it is not possible to slice meat at high speed.

At the time of abrasion of the circular knife blade, the left and right thicknesses of the sliced meat are not uniform, in view of an instant grinding function and a reciprocating feature by a

grindstone grinder, to thereby cause a low quality.

In the case of the chilled meat slicer, the sliced meat may be torn when meat is sliced at the state that the meat surfaces are not rapidly frozen in a freezer. Accordingly, meat should be necessarily rapidly frozen. The chop cutter which performs meat slicing at high speed has a problem that a knife blade should be replaced periodically, due to the blade abrasion according to the number of times of slicing meat, in which the shape of the knife blade is a half-moon shape or cochleatus shape. Here, one side of the knife blade is used as a hinge point, and fixed to the rotational axis by a bolt. Accordingly, the knife blade performs meat slicing by a fodder-chopper revolving meat slicing method. As a transfer method according to a thickness of the sliced meat, and a frozen meat chop cutter is made to bite the rear portion of meat by about 30mm with a tong gripping assembly and then transferred straightly. As a result, the bitten portion of the meat is not used.

In the case of the chilled meat chop cutter, part of sliced meat falls down to a space which is provided between a transfer loading box and a discharge conveyor and through which a knife blade passes due to a defect that meat sticks at the knife blade when meat is sliced at the state where the meat has no frozen portions . Moreover, it is impossible to slice meat of 2mm thick or below with a fodder-chop type slicing system.

Segmental cutters which slice only rawmeat are used inminiature meat shops. However, the segmental cutters have difficulties in

adjusting the thickness of the sliced meat.

Korean Utility-model Registration No.20-0337926 (26 December 2003) and relevant Korean Design Registration No. 30-0378196 (25 March 2005) disclose a meat slicer having two circular knife blades for the first time in the world. Here, a revolving axis is fixed to a revolving unit shaft holder to the left and right at the state where the revolving axis is fixed, and thus a revolving/rotating frame revolves and rotates. Thus, in the commercialized step, the revolving radius cannot be reduced. As a result, the meat slicer becomes large in size, and the meat slicing speed is limited. It is impossible to use knife blades, in combination, for slicing the frozen and chilled meat.

Therefore, the conventional meat slicer requires much time and cost, and causes a variable quality level according to the skill of operators. Based on the space limit in and the increment of the large distribution store according to change of the consumption structure, a revolving/rotating meat slicer for slicing the rawmeat, the chilled meat, and the frozen meat, simultaneously at high speed, is required.

Best Mode for Carrying out the Invention Hereinbelow, a belt power transmission type ultrahigh speed revolving/rotating meat slicer according to the present invention will be described with reference to the accompanying FIGS .1 through 16B.

The present invention and the conventional art are compared in the following Table.

(TABLE)

In particular, as shown in FIGS. 2B, and HA through 12B, a revolving unit 200 which revolves circular knife blades inserts a revolving axis 206 onto the outer coupling surface of a revolving/rotating axis 301 which is a fixed body of a hollow shaft shape and couples the revolving axis 206 with revolving axial bearings ⁽ A and B) 207. Then, an oil seal 204 for the revolving axial bearing (A) is inserted into the revolving axial pulley 203 on the left-side coupling surface of the revolving axis 206, and an oil seal 204 for

the revolving axial bearing (B) is inserted onto the coupling surface of the central portion of the revolving/rotating frame 209.

The oil seals 204 are fixed by a tightening bolt, respectively.

Moreover, a revolving/rotating frame balance weight (A) 201 which is located in the upper side of the revolving/rotating frame 209 and a revolving/rotating frame balance weight (B) 211 which is located in the side of the revolving/rotating frame 209 are fixed by fixing bolts, respectively, to thereby balance the centroid according to the center of gravity. The present invention improves the above-described disadvantages in the Table, and prevents raw meat from sticking to circular knife blades during slicing rawmeat . For this purpose, a speed-controlled inverter is additionally installed in a rotating motor 101 and a revolving motor 201, respectively. A revolving/rotating frame 209 is made of duralumin-contained alloy among aluminium materials in order to be fabricated lightly and firmly to operate at the revolving maximum speed of 330~360rpm. The revolving/rotating frame 209 is mechanically machined for maintaining material strength even if a fabrication cost becomes slightly high.

Even if water cleaning has been performed according to use of the revolving/rotating meat slicer, the oil seals combined in the revolving/rotating meat slicer prevent the water from leaking into the revolving/rotating meat slicer and thus enhances lives of the components in the revolving/rotating meat slicer.

A revolving motor M2 and a pulley 201 transmits power to a revolving axial pulley 203 by means of a revolving belt 202. In this case, the revolving/rotating frame 209 having the circular knife blades mounted thereon is made to rotate, which acts as the revolving unit 200 forming revolving of the circular knife blades 124 and 125.

The revolving speed of the revolving motor (M2) 201 whose number of poles is eight is automatically controlled at 900rpmby an inverter.

As shown in FIGS. HA through 12B, a revolving/rotating unit

300 inserts a rotating axis 105 onto the inner coupling surface of the revolving/rotating axis 301 and couples the rotating axis 105 with rotating axial bearings (A and B) 106 supporting the left- and right-sides of the rotating axis 105. Then, an oil seal 304 for the rotating axial bearing (B) is inserted into the revolving/rotating axial bearing holder 303 on the right-side of the revolving/rotating axis 301, and an oil seal 304 for the rotating axial bearing (A) is inserted onto the revolving/rotating axial bearing holder 302 on the left-side of the revolving/rotating axis 301. The oil seals 304 are fixed by a tightening bolt, respectively. Here, the revolving/rotating axis 301 is formed to make the rotating axis 105 rotate.

The rotating axis pulley 103 is coupled in the left side of the rotating axis 105, and revolving axis tension pulleys (A and B) 107 are coupled on the right side end coupling surface of the rotating axis 105, using two tightening bolts. In this manner, the rotating axis 105 is formed to transmit power to the inner side central

portion of the revolving/rotating axis 301. The revolving/rotating unit 300 is formed to maintain a tensile force of a knife blade belt 109, since the tension pulley (A) 107 is finitely controlled by six tension bolts which are located toward the tension pulley(B)107.

As shown in FIGS . HA through 12B, the rotating unit 100 inserts a knife blade axis 113 onto the inner coupling surface of the revolving/rotating frame 209 in which the circular knife blades 124 and 125 are mounted, and couples the knife blade axis 113 with knife blade axial bearings (A and B) 114 supporting the left- and right-sides of the knife blade axis 113. Then, oil seals 116 for the knife blade axial bearings (A and B) 115 are inserted into the knife blade axial bearing holders 115. The oil seals 116 are fixed to the coupling surfaces of the left- and right-sides of the revolving/rotating frame 209by a tightening bolt, respectively. Thereafter, a rotating knife blade axial pulley 110 is inserted into the protruding section of the right side of the knife blade axis 113 and thus a knife blade axial knife blade mounting holder 123 is engaged by a tightening bolt. Then, a frozen meat slicing knife blade 124 which plays a role of slicing frozen meat at high speed is formed on the rear surface of the outer portion of the holder 123 which is a knife blade coupling surface so as to be coupled by a tightening bolt, respectively. At the time of slicing raw and chilled meat, a chilled meat slicing knife blade 125 is coupled in the rear surface of the holder 123 and the end portion of the knife blade axis 113, and engaged with

a knife blade fixing washer 126 and a knife blade fixing bolt 127.

Here, the frozen meat slicing knife blade and the chilled meat slicing knife blade can be replaced with each other.

A rotatingmotor Ml and a pulley 101 transmits power to a rotating axial pulley 103 coupled with the rotating axis 105 by means of a rotating belt 102. In this case, the rotating axial tension pulleys (A and B) 107 transmit power to a rotating knife blade axial pulley 110 coupled with the knife blade axis 113 by means of a knife blade 109. Accordingly, circular knife blades 124 and 125 supported by the revolving/rotating frame 209 are made to rotate, which acts as the rotating unit 100 forming rotation of the circular knife blades 124 and 125.

The knife blade rotational speed of the rotating motor (Ml) 101 whose number of poles is four is automatically controlled at 1800rpm by an inverter.

In operation, a numerical value of thickness of meat to be sliced is established in a control panel 310, according to the kind of meat, and then a knife blade of a rotating motor 101 controlled by an inverter is made to operate at high speed and a revolving motor 201 controlled by the inverter is made to operate at an intermediate speed, during slicing raw and chilled meat, to thereby enhance an effect of making qualities of processed products become uniform, while the revolving motor controlled by the inverter is made to operate at the maximum speed to thereby enhance a productivity.

Referring to FIGS. HA and HB together with FIGS. 5B and 5C, the revolving/rotating base unit 400 of the present invention will be described below. As shown in FIGS. HA and HB together with FIGS.5B and 5C, a revolving/rotating axle holder base 305 is coupled with and supported to the revolving/rotating base unit 400 by tightening bolts at an inclined angle, to thereby enhance a meat slicing efficiency. Accordingly, the revolving/rotating meat slicer can slice all kinds of meat such as raw, chilled and frozen meat at ultrahigh speed using the replaceable circular knife blades 124 and 125.

The revolving/rotating axle holder base 305 is coupled with base front pillar boards (A and B) 404 by tightening bolts, and then base side pillar boards (A and B) 405 are engaged by tightening bolts together with an angle 413 in order to reinforce the lateral surface of the revolving/rotating axle holder base 305. Base bottom supporting plates (A and B) 409 are coupled in the lower portion of the revolving/rotating axial holder base 305, using tightening bolts. Accordingly, the revolving/rotating unit 300 is adamantly fixed. Moreover, base lower connecting plates (A and B) 452 are firmly soldered in the portion combined with the base bottom supporting plates (A and B) 409 of the left-and right-sides .of a revolving/rotating upper support 451. A revolving/rotating motor support stand 454 is united on the right side of the revolving/rotating upper support 451 and then a revolving/rotating motor base plate

455 is assembled thereon. The rotating motor 101 and the revolving motor 201 are installed on top of the revolving/rotating upper support stand 451, and are tensioned until the tensile force of the rotating belt 102 and the revolving belt 202 are secured, respectively, to then be combined with tightening bolts.

Moreover, in order to reinforce the revolving/rotating holder base 305, base reinforcement plates (A, B, and C) 401 are reinforced in the periphery of the revolving/rotating axis holder 302. In order to detachably install a grindstone grinder unit 500, base upper reinforcement plates (A and B) 407 are reinforced in the upper portion of thebase side pillar plates (AandB) 405 and engaged with tightening bolts to be coupled with grindstone fixing holders (A and B) 311.

The upper portion of the revolving/rotating side support 456 which is coupled with the revolving/rotating upper support 451 and the side support connection plates (A and B) 453 is fabricated at an inclined angle in order to enhance a meat slicing efficiency of the circular knife blades 124 and 125.

A revolving/rotating side reinforcing support 457 is coupled on the lower portion of the revolving/rotating side support 456, using tightening bolts, and then a moving wheel (caster) 463 is combined with the revolving/rotating side support 456.

FIG. 13A is a partially disassembled perspective view showing a grindstone grinder unit according to the present invention, which is viewed from southeast, and FIG. 13B is a perspective view illustrating operation of a grindstone grinder unit according to

the present invention, which is viewed from southeast.

Referring to FIGS. 13A and 13B, a grindstone grinder unit 500 will be described below. A grindstone bearing (B) 512 is inserted into a grindstone rotating axis 505, and then the grindstone rotating axis 505 is inserted into the inner central portion of a grindstone bearing holder 506. Next, a grindstone bearing (A) 512 is united with the rear portion of the holder 506, to thereby be fixed to the end portion of the grindstone rotating axis 505 using a snap ring.

A grindstone distance adjusting screw 511 is inserted into a hole at the inner side central portion of a grindstone bearing holder stopper 508, and is fixed to the end of the adjustment screw

511 using a snap ring.

The grindstone bearing holder stopper 508 is inserted into the rear portion of the grindstone bearing holder 506, and integrally coupled with each other using two dish-shaped head bolts up and down. Moreover, the integrated holder 506 and stopper 508 is inserted into the inner side central portion of a grindstone outer axis 507, and then is turned and inserted into a tap hole at the inner side central portion of a grindstone outer axis stopper 509, along the screw surface of the grindstone distance adjusting screw 511. Thereafter, the integrated holder 506 and stopper 508 is combined with the rear portion of the grindstone outer axis 507, and coupled and integrated with two dish-shape head bolts up and down.

A grindstone adjusting handle 510 is assembled along the screw surface in the end of the grindstone distance adjusting screw 511,

and engaged with a fixing nut at the rear portion thereof.

An additional grindstone is fabricated and prepared and thus two pieces of grindstone are combined as a front grindstone and a rear grindstone. The rear grindstone 503 which is used for grinding the front surface of the knife blade and the front grindstone 504 which is used for grinding the side surface of the knife blade so as to be inclined at 25° both of which are mounted on the grindstone rotating axis 505 are combined in the reverse direction as shown in FIG. 13B and a plain washer 513 is inserted and then tightened with a hexagonal nut 517.

The combined rear grindstone 503 as described above is inserted into a rear grindstone clamp 501 and the front grindstone 504 is inserted into a front grindstone clamp 502. The rear and front grindstone clamps and a grindstone outer axis 507 are tightened using tightening bolts and fixed.

Here, the rear grindstone 503 and the front grindstone 504 rotate with the top hole of the rear grindstone clamp 501 and the lower axis of the front grindstone clamp 502, and the front grindstone clamp 502 is set between side grinding angles of 25 ^° ~27 ^° of the circular knife blades 124 and 125. Then, the front grindstone clamp 502 is tightened using tightening bolts.

The operation unit of the grindstone grinding unit 500 is configured so that if the grindstone adjusting handle 510 is turned by the hand clockwise, the grindstone proceeds forward, and if the

grindstone adjusting handle 510 is turned by the hand counterclockwise, the grindstone proceeds backward. The grindstone grinding unit 500 is formed to rotate by the male screw of a grindstone distance adjusting screw 511 and the female screw of a grindstone outer axis stopper 509, and to be guided by the outer side key groove of a grindstonebearing holder 506 and a headless bolt of the grindstone outer axis 507, to thus make the grindstone transferred back and forth.

Moreover, the grindstone grinding unit 500 has no power generator, and if the grindstone is pushed in its place to the circular knife blades 124 and 125 which rotate at high speed by the power of the rotating motor (Ml) 101, the knife blades are ground of their own rotating forces .

Grindstone fixing holders (A and B) 311 combined with base upper reinforcement pins (A and B) 407 constituting the revolving/rotating base unit 400 and the grindstone grinding unit 500 are formed in a detachable manner by means of a knob 514. When the circular knife blades 124 and 125 are worn out, the revolving/rotating frame 209 is manually fitted into a hole of the inner side of the revolving/rotating frame stopper 306 combined with the revolving/rotating axis holder base 306 using the tightening bolt, and a tap of the left side of the revolving/rotating frame balance weight (A) 210 which is combined with the revolving/rotating frame 209 thereby maintaining the center of weight, and then a stopper fixing bolt 307 is inserted into and engaged with the

revolving/rotating frame 209. Accordingly, the knife blades are immediately ground.

FIG. 14A is a partially disassembled perspective view showing a loading box unit according to the present invention, which is viewed from southeast, andFIG.14B is a perspective view illustrating operation of a loading box unit according to the present invention, which is viewed from southeast.

Referring to FIGS. 14A and 14B, the loading box unit 600 will be described below. The loading box unit 600 combines a loading box transfer motor

(M3) 601 which is driven by an operational signal (revolving and operation of one time) of a proximity sensor 308 combined with the tap hole of the revolving/rotating axis holderbase 305 and a proximity sensor detection board 309 combined with the tap hole of the left-side front surface of the revolving axis pulley 203 with a speed reducer

604 , and converts a high speed rotating and a low torque of the loading box transfer motor 601 into a low speed rotating and a high torque of an output end, to thereby make a loading box transfer belt 620 and pressing rollers (A and B) 641 automatically transferred by thickness of the meat to be sliced.

An automatic transfer unit for automatically transferring meat by thickness of meat to be sliced operates as follows.

If the loading box transfer motor (M3) 601 delivers power directly to the speed reducer 604 by a clamping type coupling 603, a deceleration timing pulley (A) 607 combined with the output end

delivers power to a driving side timing pulley (B) 609 combined with a driving side roller and bush 610 by means of a timing belt 608, and thus makes a loading box transfer belt 620 combined with and driven by a driven roller 614 automatically transfer meat by thickness of the sliced meat.

The pressing rollers (A and B) 641 are driven to prevent meat from secession of position as follows.

A driving gear 613 combined with a driving roller 610 rotates simultaneously with a driven gear 624 and a chain sprocket (A) 625 which are combined with a gear shaft 622 which is connected to and driven by the counterpart axis with respect to that of the driving roller 610, and deliverers power to a driving chain 627 which is connected with and driven by a stopper.

The pressing rollers (A and B) 641 are supported by a pressing roller frame support 643 and connected with and driven by chain sprockets (B and C) 634 which are combinedwith and rotate by a pressing roller driving shaft and bush 629 playing a role of rotation and support, and thus connected with and driven by chain sprockets (D and E) 640 which are connected with and rotate by a pressing roller fixed axis and bush 636 which is fixed to and rotates by a pressing roller frame 642 by means of a driven chain 628. Accordingly, the pressing rollers (A and B) 641 are finally driven.

Moreover, in order to prevent a back slip due to a repeated stop and driving (rotation) of the loading box transfer belt 620, driving splines 612 are installed in a driving roller 610 left and

right and driven.

The loading box conveyor belt 620 and the pressing rollers

(A and B) 641 rotate reversely to each other by gears 613 and 624 which are engaged with each other and rotate. Accordingly, an effect of pressing meat and a transfer function of meat can be simultaneously accomplished. As a result, the thickness of the sliced meat can be maintained uniformly left and right at the time of transferring and slicing of meat, to thereby enhance a quality of sliced meat.

An upward manual operation unit of the pressing rollers (A and B) 641 for safely loading meat will be described below.

If a manual handle lever 646 is manipulated to make a pressing roller frame 642 rotate upwards by a pressing roller driving axis and bush 629 which is supported by a pressing roller frame support 643 and plays a role of rotational and support, a pressing roller frame stop bar 644 which is combined with the pressing roller frame support 643 and the pressing roller frame 642 performs a buffering function by means of a urethane pusher 647 and stops and makes meat put on a loading box.

A manual manipulation unit of the pressing rollers (A and B) 641 for positioning the meat loaded in the loading box in place will be described below.

If a manual handle lever 646 is manipulated to make the pressing roller frame 642 rotate inplace, a springplunger stop bar 649 combined with the pressing roller frame support 643 performs a buffering function by means of a spring plunger fixed bar 648 and a spring

plunger 650 which are combined with the pressing roller frame 642, and stops .

As described above, the loading box unit 600 employs a belt conveyor mechanism which combines the loading box transfer motor (M3) 601 which is driven by the operational signal (revolving and operation of one time) of the proximity sensor 308 and the proximity sensor detection board 309 with the speed reducer 604, and converts a high speed rotating and a low torque of the loading box transfer motor 601 into a low speed rotating and a high torque of an output end, to thereby make a loading box transfer belt 620 and pressing rollers (A and B) 641 automatically transferred by thickness of the meat to be sliced. Accordingly, when the circular knife blades pass through meat, an amount of unnecessarily wasted meat is reduced and a quality of thickness in sliced meat becomes uniform. FIG. 15A is a partially disassembled perspective view showing a discharge conveyor unit according to the present invention, which is viewed from southeast, and FIG. 15B is a perspective view illustrating operation of a discharge conveyor unit according to the present invention, which is viewed from southeast. Referring to FIGS. 15A and 15B, a discharge conveyor unit 700 will be described below.

According to the specification of the discharge conveyor unit 700, a conveyor speed is controlled by the control panel 310 at an automatic transmission mode of 0-35m/min. The conveyor speed is controlled depending upon a user's circumstance.

If a discharge conveyor motor (M4) 701 is driven by manipulation of the control panel 310, a motor-end timing pulley

(A) 703 deliverers power to a driving-end timing pulley (B) 705 by means of a timing belt 704. Accordingly, a driving-end roller 706 is driven and a discharge conveyor belt 715 is transferred in linkage with a driven-end roller 710. As a result, the transferred sliced meat is stored by a meat support 716 which is attached to the end of the conveyor.

Moreover, an oil seal is inserted into a bearing contact portion located in the inner side of a driving-end bearing and oil seal holder

707 supporting the driving-end roller 705, in order to protect the bearing from water cleaning.

A driven-end roller axis 711 is inserted into the inner side of the driven-end roller 710, and a tension bush 713 and a driven-end tension bracket holder 712 are combined with each other at the end of the axis, in order to control tension of the loosened belt. Moreover, in order to prevent the belt from sagging, a food sanitary belt sagging preventive plate 717 is installed in the upper portion of a guide support 723, and a support bracket 720 and a belt sagging preventive axis 718 are combined with each other in the left and right of the lower portion of the guide support

723. Accordingly, a belt sagging phenomenon can be prevented. Further, a pillar support 722, a lower reinforcing member

724, a vertical bracket 725, and a motor support 726 are fixed to the support bracket 720 using tightening bolts.

The rotating unit 100, the revolving unit 200, the revolving/rotating unit 300, the revolving/rotating base unit 400, the grindstone grinder unit 500, the loading box unit 600, and the discharge conveyor unit 700 are operationally manipulated in the control panel 310.

The rotating motor (Ml) 101 is used to control the speed of circular knife blades 124 and 125 and the revolving motor (M2) 201 controls the number of times of slicing meat per minute using an inverter. As described above, the belt power transmission type ultrahigh speed revolving/rotating meat slicer can make raw meat sliced into a thickness of one millimeter or less, using replaceable circular knife blades 124 and 125 such as a respective frozen and chilled meat slicing blade. To enhance a meat slicing efficiency, the revolving/rotating base unit is formed at a predetermined inclined angle .

According to the kind of meat, a knife blade of the rotating motor 101 controlled by an inverter is made to operate at high speed and that of the revolving motor controlled by the inverter is made to operate at an intermediate speed, during slicing raw and chilled meat, to thereby enhance an effect of making qualities of processed products become uniform, while the revolving motor controlled by the inverter is made to operate at the maximum speed during slicing frozen meat, to thereby enhance a productivity. Further, the present invention makes the loading box transfer belt

620 and pressing rollers (A and B) 641 automatically transferred by thickness of the meat to be sliced. Accordingly, when the circular knife blades pass through meat, an amount of unnecessarily wasted meat is reduced and a quality of thickness in sliced meat becomes uniform.

Further, oil seals or 0-rings are inserted into bearing contact portions between the components, to thereby protect the bearings from water cleaning and thus extend lives of the meat slicer and components. As described above, the present invention has been described with respect to particularly preferred embodiments. However, the present invention is not limited to the above embodiments, and it is possible for one who has an ordinary skill in the art to make various modifications and variations, without departing off the spirit of the present invention. Thus, the protective scope of the present invention is not defined within the detailed description thereof but is defined by the claims to be described later and the technical spirit of the present invention.

Industrial Applicability

As described above, the present invention provides a belt power transmission type ultrahigh speed revolving/rotating meat slicer which can perform functions of a segmental cutter and a chop cutter as well as a meat slicing function, in order to play a role of a multi-purpose meat processing machine for processing meat by

part or kind thereof. Since the frozen and chilled meat slicing blade can be automatically operated and replaced under the control of a control panel, the raw, chilled, and frozen meat can be simultaneously cut or sliced at a meat slicing minimum thickness of 0.5mm, a meat slicing maximum speed of 330-360 times per minute, and a meat slicing maximum width of 350mm.
