Description
VACUUM DRY METHOD AND THE DEVICE THAT DO FOR THE SAKE OF CHARCOAL FORMING
Technical Field
[1] The present invention relates to a vacuum dry kiln that controls moisture of a panel having various functions, processed by cutting a raw lumber is molded into charcoal, and more particularly, to a dry method for charcoal forming and a dry device therefor, in which a various shaped receptacles panels processed by cutting a lumber are put in a vacuum dry kiln and then processed into charcoal by exhausting moisture and poroligenous liquor contained in the raw lumber through a far- infrared heater without defect. Background Art
[2] EFFICACY OF CHARCOAL
[3] A conventional method for manufacturing a forming product or a forming material using charcoal is disclosed in the Korean Patent Publication No. 2003-68097 published on August 19, 2003 and the Korean Patent Publication No. 2003-58981 published on July 7, 2003.
[4] In the Korean Patent Publication No. 2003-68097, separate process such as heat dry, surface polishing, and cooling is performed in a state that various impurities are injected into a charcoal powder which is a main material, thereby improving strength, having hygroscopic property, and preventing surface bleach from occurring.
[5] In particular, the Korean Patent Publication No. 2003-58981 discloses a method for manufacturing a carbon forming material in which charcoal, volatile powder, ash powder, and poroligenous liquor are mixed at a certain ratio to form a certain shape and then a coating layer is formed by heating and re-heating and mixture of charcoal and Teflon fluororesin solution on a fine powder, so as not to allow cooking stuffs to be stuck or burned.
[6] However, in the conventional method for manufacturing a forming product or a forming material, the forming product or the forming material is obtained by mixing impurities with a powdered charcoal, wherein the charcoal is made by powdering wood. Accordingly, the conventional method for manufacturing a forming product or a forming material has a drawback in that it fails to provide inherent functions of charcoal.
[7] Various examples of a conventionally processed article made of a raw lumber include wooden containers, vessels for memorial service of the deceased, and a rice chest. However, if the conventionally processed article is used as charcoal, various
kinds of deformation such as distortion or split occur in the article while the article is varied to charcoal, thereby causing the article to be unavailable. [8] Furthermore, the deformed article cannot be used by re-processing. Even though the wooden article is varied to charcoal, it has a drawback in that it cannot be used as a living article due to low strength. [9] The wooden article has been manufactured such that various trees such as a zelkova tree, an ash tree, and a ginkgo tree are dried by natural seasoning and then rotated to process various articles such as wooden containers or vessels for memorial service of the deceased by using the blade of a knife, and the processed articles are finally dried and lacquered for use. However, it has not found that the wooden article had been processed as charcoal. [10] In particular, after the wooden article is processed, if the processed article is put in a kiln to manufacture charcoal, a moisture content increases to cause a defect article which has split or fails to maintain a desired size or shape, whereby the defect article cannot be used. [11] If the processed article is dried sufficiently under the natural condition, much time is required, and diurnal range occurs severely depending on season, whereby it is difficult to maintain moisture of a desired content.

Best Mode for Carrying Out the Invention
[54] ( 1 ) Preparation step of forming product
[55] A raw lumber which has been picked is naturally dried to process a rectangular shape or a circular shape containing moisture of 25% to 39% and having a certain size and thickness to form a vessel or various articles, whereby a forming product is manufactured or a plate is formed.
[56] (2) Vacuum dry step
[57] After the raw lumber is supplied to the loading area 21 of the vacuum dry kiln 10, the far- infrared heater 25 is heated so that a temperature of 105 to 115 0 C is maintained. The vacuum pump 33 of the vacuum absorbing device 30 is driven so that the loading area 21 is maintained under the vacuum state.
[58] At this time, the forming product supplied to the loading area 21 is heated by the maintained temperature and the moisture generated under the vacuum state is exhausted from the vacuum hole 31 to the pipe 32 1. This state is maintained for 6 ~8 days, so that moisture of 5% remains from that of 38%.
[59] (3) Processing step
[60] The forming product or the plate, which contains moisture of about 5%, is supplied to the kiln and then heated to manufacture charcoal. The manufactured charcoal undergoes after-processing to process various articles made of charcoal. Mode for the Invention
[61] As illustrated in Fig. 3, various good or plates are input into the loading area 21 in state of the door opened through the door switching device 40. When the door plate 42 is pushed, it is rotated according to a reference axis 44 and a moving axis 46. The screw axis 48 is connected to the fitting groove 43 of the door plate 42.
[62] When the screw axis is connected, the clamp grip 47 is connected at fitting groove
43 and the door 41 is connected into the main body 20 to be a single body.
[63] After closing the loading area 21 through the door switching device, the vacuum pump 33 is operated at control box 26 in a water pipe method. It makes the loading area 21 to be vacuum state. Far- infrared 25 makes the temperature the loading area to 105 - 115 0 C.
[64] The vacuum pump 33 makes the loading area 21 vacuum state at vacuum hole 31 by the pipe 32 and simultaneously absorbs the moisture originated at the loading area 21.
[65] The loading area 21 keeps the vacuum state and the temperature thereof 190-210 0 C, therefore, the moisture and poroligenous liquor is discharged. The discharged water and poroligenous liquor are gathered at a absorption tank 34 through the vacuum hole 31.
[66] The absorption capacity of the vacuum pump 33 is to the certain point of -20 cm/
Hg.
[67] If 6 - 8 days are passed in the condition of 105 - 115°C and vacuum state, the moisture and poroligenous liquor is discharged as 38 % of the moisture of various good and plates is going to be 5 %.
[68] The moisture and poroligenous liquor continuously discharged from the vacuum pump are provided to the absorption tank. The inside of the absorption tank 34 keeps mixed state with the moisture and extracted liquid of certain tree. By circulation with pumping, the moisture of bottom area circulates to upper area through the connection pipe 35. Due to the moisture and poroligenous liquor is regular temperature, all the moisture is evaporated in circulation. Finally, only the poroligenous liquor is left.
