<45>

<46> Load cell is generally used in the ordinary field of the industry so detailed illustration is skipped to briefly focus on the function. Sensor of load cell(136) compresses or stretches and this is when the actual weight converts to numbers as the computer system changes the electric signal - from variable amount detected by variable measuring device - into digital signal.

<47>

<48> Next, power transmission apparatus(140) is installed on one side of the main body(llθ) and consists of hydraulic cylinder(142) that works jointly with conveyor belt(120) or separately and drive motor(148) installed on one side of the hydraulic revolving cylinder(142) to make it spin.

<49> Elements of the power transmission apparatus(140) and joint relationship to conveyor belt(120) will be illustrated further.

<50>

<5i> Hydraulic revolving cylinder(142) spins upon the backward movement of piston(144), powered with the hydraulic pressure, inside the cylinder(143). Herewith the hydraulic pressure is replaceable with air pressure. Details on hydraulic revolving cylinder(142) is skipped as it is normally used in the ordinary field of the industry but the operational details will be illustrated further.

<52>

<53> The liquefaction device (150) is installed inside the rear part of main body (110) that liquefies steam from the drying process. Please refer to following for detail.

<54>

<55> Installed in the rear part of the main body, the vacuum pump decompresses to keep the inner space vacuumed, which is generally applied to the ordinary field of the industry. Hence detailed explanation is skipped.

<S6>

<57> On the front of the liquefaction device(150) is equipped with screen net(170) attached inside of the main body(llθ), which has numerous pores.

<58>

<59> Following paragraphs will describe what elements consist of this invention and how they are combined each other. <60> <6i> Drawing 3 illustrates the conveyor belt and power transfer apparatus from perspective view operated in a preferential way. (a) & (b) of drawing 4 illustrate how the conveyor belt and power transfer apparatus operate from a schematic view of section part A-A.

<62>

<63> Conveyor belt(120) in drawing 3 features, like normal conveyor belts(120), frame(122), spinning roller(124) on the front and back of the frame(122) and belt(125) embracing spinning roller(124) ,but in case of this invention, additionally is equipped with supporting legs(126) that are inserted individually into connecting trap(114) on the lower part of the main body(llθ) and one side of spinning roller(124) has nut lock type 1 with multi-angled nut hole(128).

<64>

<65> Power transmission apparatus(140) consists of hydraulic revolving cylinder(142) and drive motor(148) connected via a belt(149) to spin the hydraulic revolving cylinder(142). In detail, the hydraulic revolving cylinder(142) consists of a cylinder(143) attached to the main body(llθ) and a piston(144) sliding by the hydraulic pressure. On the one end of the piston(144) is nut lock type 1(145) with plug(146) connecting to multi-angled nut lock type 1(127) and on the other end is pulley(147) connecting to drive motor(148) and belt(149).

<66>

<67> From the magnified one, nut hole(128) of the nut lock type 1(127) is multi-angled while the plug(146) of nut lock type 2(145) is also multi-angled to connect to nut hole(128).

<68>

<69> It is preferred that nut hoie(128) should be longer to a degree for the plug(146)

so that it can be easy to combine even when nut hoie(128) of nut lock type 1(127) moves vertically.

<70>

<7i> Following paragraphs will describe how the above featured conveyor belt(120) and power transfer apparatus(140) work.

<72>

<73> In part (a) of drawing 4, conveyor belt(120) is equipped inside the main body(llθ) and nut lock type 1(127) is equipped in spinning roller(124) of conveyor belt(120). On one end of the nut lock type 1(127) is the cylinder(143) of the hydraulic revolving cylinder(142) is equipped on the main body(llθ) and one end of the piston(144) equipped with nut lock type 2(145) is placed with a certain distance and the other end of the ρiston(144) equipped with pulley(147) is connected to drive motor(148) from the outside of the main body(148).

<74>

<75> Nut hole(128) of nut lock type 1(127) and plug of nut lock type 1(145) will be fitting when the hydraulic revolving cylinder(142) operates to connect the two equipped on one end of the piston(144).

<76>

<77> In part (b), plug(146) of nut lock type 2 connects to nut hole(128) of nut lock type 1(127) when piston(144) slides. As multi-angled, they will be spinning together. Drive motor(148) operates to spin piston(144) to spin the spinning roller(124) of the conveyor belt(120). With piston(144) sliding backwards, plug(146) of nut lock type 2(145) detaches from nut hole(128) of nut lock type 1(127).

<78>

<79> Weight measuring apparatus(130) operates more accurately with conveyor belt(120) because conveyor belt(120) and power transmission apparatus(140) are separated and designed not the touching each other when not in use.

<80>

<8i> (a) of drawing 5 illustrates the weight measuring apparatus from perspective view and (b) of it from vertical view of the section part operated in a preferential

way. Drawing 6 illustrates how the weight measuring apparatus works by magnifying part "A" of drawing 2 from a schematic view operated in a preferential way.

<82>

<83> In drawing 5, weight measuring apparatus(130) consist mainly of joint(131) and load eel1(136). And joint(131) consist of jacket(132), moving bar(135) and cover(137).

<84>

<85> Lower part of the jacket is flange(133) whose floor has packing(134) that faces load cell(136). Moving bar(135) slides into jacket(132) while the lower part touches the sensor of load cell(136). Cover(137) firmly ties load cell(136) and flange(133) of jacket(132).

<86>

<87> In drawing 6, jacket(132) is attached to the outer wall of connecting trap(114) on the lower part of main body(llθ); moving bar(135) is inserted inside the jacket(132); support legs(126) of conveyor belt(120) are placed on the upper part of the moving bar(135). Moving bar(135) is placed on the sensor of load eel1(136) and flange(133) on the lower part of jacket(132) and cover(137) are firmly tied together located in the middle of load eel1(136). With packing(134) on the lower part of flange(133) of jacket(132), it is sealed tightly. And the load cell(136) is connected to computer system not illustrated in the drawing.

<88>

<89> Apparently, in the connecting trap(114) on the rear part of the main body(llθ), weight measuring apparatus(130) supports the supporting legs(126) of the conveyor belt(120) as well.

<90>

<9i> Conveyor belt(120) combines with the power transmission apρaratus(140) only when spinning and is separated when drying or when not in use so that it is supported by load eel1(136) via joint(131) of weight measuring aρparatus(130). Therefore load eel1(136) of conveyor belt(120) can weigh the raw material(200) at any required time.

<92>

<93> Drawing 7 illustrates the liquefaction device from perspective view operated in a preferential way. Drawing 8 illustrates how the liquefaction device works by magnifying part "B" from a schematic view operated in a preferential way.

<94>

<95> In drawing 7, liquefaction device(lδθ) consist of panel(152), duct(154), freezer(156) and filler pump(158).

<96>

<97> Several ρanels(152) are placed separately. Curbed Duct(154) is equipped in between the panel(152) whose one end is connected to freezer(156) and the other to filler pump(158). Abovementioned freezer(156) and filler pump(158) are connected through other ducts. uct(154) is curbed in U-shape as thick and high as panel(152) and panel is inserted and attached in between the ducts(154).

<98>

<99> Following is the operational detail of liquefaction device(150) based on drawing 8. Panel(152) of liquefaction device(150) is installed inside the rear part of the main body(llθ). Panel(152) is welded or bolted to be installed inside the main body(llθ). In between the panels(152), one end of duct(154) connects to freezer(156) outside the main body(llθ) and the other end to filler pump(158). To evaporate the steam more efficiently in the main body(llθ), the panel(152) is installed vertically. Screen net(170) is installed in front of liquefaction device(150). This is not to lose microwave from upper part of main body(llθ) in the rear part where the raw material (200) is not located. Steam goes through the pores in the screen net(170) located in the front side of the liquefaction device(150).

<10Q>

<ioi> Freezer(156) cools down water and filler pump(158) constantly circulates the cool water through duct(154). In this process, duct(154) and each panel(152) attached to it are frozen by the water. Liquefied steam, as in a form of water, will drop to the floor of the main body(llθ) while moving over to panel part of the liquefaction device(150) out of the pore of screen net(170). Of course, water comes outside through drain(llβ) in the main body(llθ).

<102>

<iO3> (a) & (c) of drawing 9 illustrates how the microwave vacuum dry device works from a schematic view operated in a preferential way.

<104>

<io5> (a) is the vertical version of schematic section view and (b) the horizontal one of microwave vacuum dry device(lOO).

<106>

<iO7> Piston(144) of power transmission apparatus(140) slides to connect the plug(146) of nut lock type 2(145) to the nut hole(128) of nut lock type(127) equipped in the spinning roller(124) of conveyor belt(120). Drive motor(148) operates to move conveyor belt(120) into back of the main body(llθ) and opens door in the front side of the main body(llθ) to supply raw material onto the belt(125) of conveyor belt(120). Raw material(200) supply continues until it moves to the very end of the conveyor belt(120) and the drive motor(148) stops here.

<108>

<iO9> Even if it is not illustrated in the drawings, the piston(144) of power transmission apparatus(140) slides in the reverse direction to separate the plug(146) of nut lock type 2(145) from nut hole(128) of nut lock type 1.

<πo>

<πi> Power transmission apparatus(140) separates from conveyor belt(120) to let the conveyor belt(120) stand on the weight measuring apparatus(130) via support legs(126). Then the load cell(136) of the weight measuring apparatus(130) weighs the raw material placed on the conveyor belt(120) via joint(131).

<112>

<ii3> (c) part of the drawing illustrates the liquefaction device(150) operation and the vacuum ρump(160) operation to decompress the inner space of the main body(llθ). At the same time, magnetron(llδ) in upper part of the main body(llθ) operates to beam microwave. Most of the microwave avoids loss while moving to the backwards due to screen net(170) and dry the raw material(200). As time passes by, steam comes from raw material(200) on the conveyor belt(120). Steam transfers to the backward of the main body(llθ) due to the decompression effect of vacuum

pump(160). Going through liquefaction device(lδθ), steam liquefies mostly and some of it will be discharged out of the main body(llθ) via vacuum pumρ(160). Most of liquefied steam drops to the floor of the main body(llθ) as the panel(152) of liquefaction device(lδθ) keeps the status frozen. Of course, the water drop on the floor of the main body(llθ) will flow out through drain(116).

<114>

<ii5> Liquefaction device(lδθ) equipped in front of vacuum pump(160) disposes most of the steam inside the main body(llθ) , which avoids overload, needs for larger capacity, minor breakdown and increases work productivity drastically at the same time.

<116>

<ii7> Certain amount of times passes until the raw material(200) completes dry. User may well calculate accurately the weight variance before and after the dry process as the load cell(136) of conveyor belt(120) supporting weight measuring apparatus(130) constantly operates.

<118>

<ii9> Once dry completes, door(112) opens in front of the main body(llθ) and piston(144) works to connect plug(146) of the nut type 2(145) to nut hole(128) of nut lock type 1(127) again.

<12O> Drive motor(148) spins in the reverse direction and the user let the dried material come out of the open door(112). Detailed illustration of elements and operation of microwave vacuum dry device(lOO) is as above.

<121>

<122> This is a very useful invention in terms of productivity and time efficiency because of 1) enabled real time weight verification due to direct linkage to load cell(136) of weight measuring apparatus(130) from conveyor belt(120) via joint(131), 2) easier discharge of steam due to liquefaction device(150), and 3) prevention of overload of vacuum pump(160) due to #2).

<207> In part (b), plug(146) of nut lock type 2 connects to nut hole(128) of nut lock type 1(127) when piston(144) slides. As multi-angled, they will be spinning together. Drive motor(148) operates to spin piston(144) to spin the spinning roller(124) of the conveyor belt(120). With piston(144) sliding backwards, plug(146) of nut lock type 2(145) detaches from nut hole(128) of nut lock type 1(127).

<208>

<209> Weight measuring apparatus(130) operates more accurately with conveyor belt(120) because conveyor belt(120) and power transmission apparatus(140) are separated and designed not the touching each other when not in use.

<210>

<2ii> (a) of drawing 5 illustrates the weight measuring apparatus from perspective view

and (b) of it from vertical view of the section part operated in a preferential way. Drawing 6 illustrates how the weight measuring apparatus works by magnifying part "A" of drawing 2 from a schematic view operated in a preferential way.

<212>

<2i3> In drawing 5, weight measuring apparatus(130) consist mainly of joint(131) and load cell(136). And joint(131) consist of jacket(132), moving bar(135) and cover(137).

<214>

<2i5> Lower part of the jacket is flange(133) whose floor has packing(134) that faces load eel 1(136). Moving bar(135) slides into jacket(132) while the lower part touches the sensor of load cell(136). Cover(137) firmly ties load cell(136) and flange(133) of jacket(132).

<216>

<2i7> In drawing 6, jacket(132) is attached to the outer wall of connecting trap(114) on the lower part of main body(llθ); moving bar(135) is inserted inside the jacket(132); support legs(126) of conveyor belt(120) are placed on the upper part of the moving bar(135). Moving bar(135) is placed on the sensor of load eel1(136) and flange(133) on the lower part of jacket(132) and cover(137) are firmly tied together located in the middle of load cell(136). With packing(134) on the lower part of flange(133) of jacket(132), it is sealed tightly. And the load cell(136) is connected to computer system not illustrated in the drawing.

<218>

<2i9> Apparently, in the connecting trap(114) on the rear part of the main body(llθ), weight measuring apparatus(130) supports the supporting legs(126) of the conveyor belt(120) as well.

<220>

<22i> Conveyor belt(120) combines with the power transmission apρaratus(140) only when spinning and is separated when drying or when not in use so that it is supported by load cell(136) via joint(131) of weight measuring apparatus(130). Therefore load eel1(136) of conveyor belt(120) can weigh the raw material(200) at any required time.

<222>

<223> Drawing 7 illustrates the liquefaction device from perspective view operated in a preferential way. Drawing 8 illustrates how the liquefaction device works by magnifying part "B" from a schematic view operated in a preferential way.

<224>

<225> In drawing 7, liquefaction device(150) consist of panel(152), duct(154), freezer(156) and filler pump(158).

<226>

<227> Several panels(152) are placed separately. Curbed Duct(154) is equipped in between the panel(152) whose one end is connected to freezer(156) and the other to filler pump(158). Abovementioned freezer(156) and filler ρump(158) are connected through other ducts. uct(154) is curbed in U-shape as thick and high as panel(152) and panel is inserted and attached in between the ducts(154).

<228>

<229> Following is the operational detail of liquefaction device(150) based on drawing 8. Panel(152) of liquefaction device(150) is installed inside the rear part of the main body(llθ). Panel(152) is welded or bolted to be installed inside the main body(llθ). In between the panels(152), one end of duct(154) connects to freezer(156) outside the main body(llθ) and the other end to filler pump(158). To evaporate the steam more efficiently in the main body(llθ), the panel(152) is installed vertically. Screen net(170) is installed in front of liquefaction device(150). This is not to lose microwave from upper part of main body(llθ) in the rear part where the raw material (200) is not located. Steam goes through the pores in the screen net(170) located in the front side of the liquefaction device(150).

<230>

<23i> Freezer(156) cools down water and filler pump(158) constantly circulates the cool water through duct(154). In this process, duct(154) and each panel(152) attached to it are frozen by the water. Liquefied steam, as in a form of water, will drop to the floor of the main body(llθ) while moving over to panel part of the liquefaction device(150) out of the pore of screen net(170). Of course, water

comes outside through drain(llβ) in the main body(llθ).

<232>

<233> (a) & (c) of drawing 9 illustrates how the microwave vacuum dry device works from a schematic view operated in a preferential way.

<234>

<235> (a) is the vertical version of schematic section view and (b) the horizontal one of microwave vacuum dry device(lOO).

<236>

<237> Piston(144) of power transmission apparatus(140) slides to connect the plug(146) of nut lock type 2(145) to the nut hole(128) of nut lock type(127) equipped in the spinning roller(124) of conveyor belt(120). Drive motor(148) operates to move conveyor belt(120) into back of the main body(llθ) and opens door in the front side of the main body(llθ) to supply raw material onto the belt(125) of conveyor belt(120). Raw material(200) supply continues until it moves to the very end of the conveyor belt(120) and the drive motor(148) stops here.

<238>

<239> Even if it is not illustrated in the drawings, the piston(144) of power transmission apparatus(140) slides in the reverse direction to separate the plug(146) of nut lock type 2(145) from nut hole(128) of nut lock type 1.

<240>

<24i> Power transmission apparatus(140) separates from conveyor belt(120) to let the conveyor belt(120) stand on the weight measuring apparatus(130) via support legs(126). Then the load eel 1(136) of the weight measuring apparatus(130) weighs the raw material placed on the conveyor belt(120) via joint(131).

<242>

<243> (c) part of the drawing illustrates the liquefaction device(150) operation and the vacuum pump(160) operation to decompress the inner space of the main body(llθ). At the same time, magnetron(118) in upper part of the main body(llθ) operates to beam microwave. Most of the microwave avoids loss while moving to the backwards due to screen net(170) and dry the raw material(200). As time passes by, steam comes from raw material(200) on the conveyor belt(120). Steam transfers

to the backward of the main body(llθ) due to the decompression effect of vacuum pump(lβθ). Going through liquefaction device(150), steam liquefies mostly and some of it will be discharged out of the main body(llθ) via vacuum pump(160). Most of liquefied steam drops to the floor of the main body(llθ) as the panel(152) of liquefaction device(150) keeps the status frozen. Of course, the water drop on the floor of the main body(llθ) will flow out through drain(116).

<244>

<245> Liquefaction device(150) equipped in front of vacuum pump(lβθ) disposes most of the steam inside the main body(llθ) , which avoids overload, needs for larger capacity, minor breakdown and increases work productivity drastically at the same time.

<246>

<247> Certain amount of times passes until the raw material(200) completes dry. User may well calculate accurately the weight variance before and after the dry process as the load cell(136) of conveyor belt(120) supporting weight measuring apparatus(130) constantly operates.

<248>

<249> Once dry completes, door(112) opens in front of the main body(llθ) and piston(144) works to connect plug(146) of the nut type 2(145) to nut hole(128) of nut lock type 1(127) again.

<250> Drive motor(148) spins in the reverse direction and the user let the dried material come out of the open door(112). Detailed illustration of elements and operation of microwave vacuum dry device(lOO) is as above.

<251>

<252> This is a very useful invention in terms of productivity and time efficiency because of 1) enabled real time weight verification due to direct linkage to load eel1(136) of weight measuring apparatus(130) from conveyor belt(120) via joint(131), 2) easier discharge of steam due to liquefaction device(150), and 3) prevention of overload of vacuum pump(160) due to #2).

<257 _> This invention is to improve the abovementioned situation so that materials can be weighed at any time and to cut down on time consumption on dry process.
