Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 and 2, a crop drying apparatus 1 using a heating sheet according to the present invention comprises a heating unit 10, a drying table 10 mounted on the heating unit 10, 20), and a cover (30) covering the drying rack (20) to keep drying conditions of the crop inside.

The crop drying apparatus 1 is also provided with an air blower 40 for allowing air to flow into the inside of the cover 30 to quickly dry the crop.

The heat generating unit 10 includes a heat insulating material 110, a heat reflecting plate 120 provided on the heat insulating material 110, and a heat generating unit 120 disposed on the heat reflecting plate 120, Sheet 130 as shown in FIG.

The heat insulating material 110 is a means for preventing the heat of the heat generating portion 10 from being lost due to a temperature difference with the ground. The heat insulating material 10 is preferably styrofoam, but is not limited thereto, and any material that can block heat can be used. The heat insulating material 10 preferably has a thickness of about 50 mm. If the heat insulating material 10 is less than 50 mm, the effect of cutting off heat on the ground is lowered.

The heat reflecting plate 120 is a means for causing the heat emitted from the heat generating sheet 130 to reflect heat to the side of the drying stand 20 to shorten the drying time. The heat reflecting plate 120 is preferably a thin plate made of aluminum. However, the heat reflecting plate 120 is not limited thereto, and any material can be used as long as it has excellent heat reflection efficiency. The heat reflecting plate 120 is preferably about 3 mm or more, and if it is less than 3 mm, heat reflection is not achieved.

The heating sheet 130 is a means for drying the crop by radiating heat using electricity provided from the outside. 3, the heating sheet 130 includes a heating body 132, a foamed fabric 134, a heat insulating layer 136, a reflective layer 138, a finish layer 139, (137), and an auxiliary finish layer (135). In addition, the heating element 132 is provided with a temperature controller 131 for adjusting the amount of electricity supplied from the outside to adjust the temperature to be radiated.

4 and 5, a heating element manufacturing step S100 for manufacturing a heating element 132 for dissipating heat and a manufacturing step S100 for manufacturing a foaming fabric 134 (S300) of joining a foaming fabric (134) to the upper and lower sides of the heating body (132), and a heat insulating layer (136) and a lower portion A first jointing step S400 for joining the reflective layer 138 to the first layer 138 and a second layer 139 for joining the second layer 142 to the second layer 142, (S500).

6, the heating element 132 is supplied with power supplied from the outside and radiates heat at a predetermined temperature. In the heating element manufacturing step S100 for manufacturing the heating element 132, as shown in FIG. 6, (S100 ') for preparing an electrically conductive composition by mixing the electrically conductive carbon black and electrically conductive carbon black, and a stirring step (S200') for stirring the diluted electrically conductive composition by mixing the liquid silicone rubber and the electrically conductive carbon black.

In addition, the heating element 132 is manufactured through a curing step S300 'in which the conductive composition obtained through the stirring step S200' is molded and cured in a certain molding frame.

In particular, the heating element 132 is formed by forming and curing a conductive composition formed by mixing a liquid silicone rubber and a conductive carbon black in a molding frame (not shown), thereby forming the heating element 132 in a mesh structure.

The composition forming step (S100 ') is a conductive composition consisting of a mixture of liquid silicone rubber and conductive carbon black, or a mixture of liquid silicone rubber and graphite powder. The mixing ratio of each composition is between liquid silicone rubber and conductive carbon black And a mass ratio of liquid silicone rubber to graphite powder is 100: 10-150. The composition thus prepared is mixed to prepare a conductive composition, and then a mixture of the liquid silicone rubber and the conductive carbon black (S200 ') in which a diluent is added at a ratio of 1 to 100% with respect to the mass of the liquid silicone rubber and the mixture is stirred.

At this time, toluene or xylene is used as the diluent, and the diluent added to the mixture through the stirring step S200 'is 0 to 100% based on the mass ratio of the liquid silicone rubber, If the content of carbon black is small in the stirring step S200 ', the flowability of the conductive composition is secured without adding a diluent. However, as the content of the carbon black is high, the fluidity becomes poor. Therefore, The flowability of the conductive composition is improved during stirring.

The conductive composition that has been subjected to the stirring step S200 'is subjected to a curing step S300'. At this time, the conductive composition is molded in various types of forming molds (not shown) And the heating element 132 receives power from the outside and generates heat to a predetermined temperature from the inside.

The heating element 132 manufactured by the manufacturing method described above is excellent in physicochemical properties such as heat resistance, cold resistance, ozone resistance and electrical insulation, and is obtained by mixing only the liquid silicone rubber, which is the same material as the conductive composition, with the diluent, The heating element 132 is coated on the surface of the heating element 132 so as to be insulated from the heating element 132. In this case, the heating element 132 is not peeled off even if the thermal expansion and the thermal shrinkage are periodically changed repeatedly. In particular, even if a part of the heating element 132 is short-circuited, the power source is bypassed and the heating element 132 is prevented from being short- 132, the power supply is smoothly supplied.

The foamed fabric 134 is interposed between the upper and lower portions of the heating body 132 to block the moisture inside the heating body 132. The heat generated from the heating body 132 is easily transferred to the outside .

The foamed fabric 134 foams the foamed mixture to produce the foamed fabric 134.

As shown in FIG. 7, the foamed mixed solution is prepared by injecting a solidifying agent into a heating tank and dissolving the solidifying agent at 500 ° C. for 5 to 10 seconds (S100 "), and dissolving the solidified agent in a mixing tank, (S300 ") for applying the mixed foamed liquid mixture to the foam line, and a step (S300 ") of applying the mixed foamed liquid to the foamed foamed foamed product (S400 ") for foaming the foaming mixture by heating for 2 seconds to produce the foamed fabric 134, and a foaming fabric step S500" for foaming the foamed foamed fabric 134 to a predetermined thickness.

The solid material dissolved in the heating tank to be mixed with the foaming agent may be any one selected from the group consisting of polyethylene (PE), polyurethane (PU), polyvinyl chloride (PVC), and polypropylene Which is dissolved in the heating tank and mixed with a foaming agent in a mixing tank to form a foaming mixture liquid.

In addition, the foamed mixture liquid in which the dissolved solid matter and the foaming agent are mixed is applied to the foam line in a liquid state, and the foam line is formed by a conveyor belt method so that the foamed foam mixture mixed in the mixing tank is evenly applied on the foam line .

Further, in order to promote foaming of the foamed mixture liquid applied to the foam line, the foamed mixture is heated at a temperature of 60 ° C to 120 ° C for 5 to 10 seconds to promote foaming of the foamed mixture.

At this time, when the foamed mixture liquid is heated at a certain temperature for a certain time, it is foamed for at least 1 m, and the foamed fabric 134 is made by slow cooling at the outside air.

Particularly, the foamed foamed fabric 134 is cut to have a predetermined thickness so as to be laminated on the upper and lower portions of the heating body 132, so that the foamed fabric 134 is easily lapped on the upper / lower portions of the heating body 132. It is preferable to make an angle of 1 to 2 mm.

The foamed fabric 134 is formed by cutting off the moisture penetrating into the heating element 132 and discharging the heating element 132 to the heating element 132 through the foaming fabric. A method of laminating the foamed fabric 134 is such that the inner surface of the foamed fabric 134, which has been cut into 1 to 2 mm, Heated to 100 ° C to 150 ° C through a flame, and wound on a top / bottom of the heating body 132, moved to a compression roller, and the foamed fabric 134 and the heating body 132 are compressed Join together.

At this time, the foamed fabric 134 heated by the heating means is heated and the inner surface of the foamed fabric 134 is melted so that the upper and lower foamed fabrics 134 are mutually bonded together with the heating element 132, The foamed fabric 134 and the heating element 132 are firmly squeezed.

A heat insulating layer 136 is formed on the foam material 134 and a reflective layer 138 is formed on the foam material 134 on the upper and lower sides of the foamed fabric 134 where the foamed fabric 134 and the heating element 132 are laminated. The heat retaining layer 136 minimizes the divergence of heat of the heating body 132 to the outside so as to keep the heat constant within the heating sheet 130. The reflective layer 138 reflects the heat transmitted to the lower portion, The power consumption is reduced and the heat generation temperature of the heating sheet 130 can be maintained for a long time even if the power supply is stopped to the heating element 132. [

The insulating layer 136 and the reflective layer 138 are formed of any one of polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP).

The thickness of the insulating layer 136 and the reflective layer 138 is preferably 0.2 mm to 0.5 mm.

The first joining method S400 for joining the insulating layer 136 and the reflecting layer 138 is a method for joining the insulating layer 136 and the reflecting layer 138 by forming a heat insulating layer 136 on the foamed fabric 134, The foamed fabric 134, the heat retaining layer 136, and the reflective layer 138 are thermally fused at 200 ° C. to 250 ° C. for 3 to 5 seconds under a pressure of 1 ton in the hot extrusion roller. At the same time, the foaming material 134, the insulating layer 136, and the reflective layer 138 are firmly connected to each other by the extrusion pressure of the hot extrusion roller.

The finish layer 139 and the moisture-proof layer 137 are formed of any one of polyethylene terephthalate (PET), polyethylene (PE), and polypropylene (PP).

A moisture barrier layer 137 is formed on the lower part of the reflective layer 138 and then heated at 200 to 250 ° C. for 3 to 5 seconds under a pressure of 1 ton in a heat extrusion roller. Fused.

At this time, the heat insulating layer 136, the finish layer 139, the reflective layer 138, and the moisture-proof layer 137 are mutually dissolved and bonded to each other by the heating temperature of the heat extrusion roller 700, They are firmly joined together by the extrusion pressure.

The thickness of the moisture-proof layer 137 and the finish layer 138 is preferably 0.2 mm to 0.5 mm. In particular, the finish layer 139 may be made of polyethylene terephthalate (PET) The adhesive layer is uniformly applied to the upper part of the finish layer 139 joined to the upper side of the heat insulation layer 136 by a hot extrusion roller, And the auxiliary finishing layer 135 made of any one of the thermoplastic resin and the thermoplastic resin is interposed between the thermally conductive sheet 130 and the thermally conductive sheet 130 to provide a comfortable use environment during use.

The drying rack 20 stores crops inside and allows the crops to be dried by the wind provided by the blower 40 and the heat provided by the heating unit 10.

In addition, a plurality of the drying racks 20 are stacked. In this case, it is preferable to use two or three stacked layers. For example, the second to third drying units 20 of the heating unit 10 are stacked, the heating sheet 130 of the heating unit 10 is placed on the drying units 20, the drying units 20 are stacked in two or three stages, The crops are dried in an arrangement manner in which the heating sheet 130 and the drying bases of two or three stages are laminated on the drying basin.

A plurality of through holes are formed in the drying table 20 so that the heat of the heat generating unit 10 and the wind of the blower 40 can communicate with each other freely. In this case, the drying table 20 may be manufactured as a perforated plate. Of course, the present invention is not limited to this, and any structure can be used as long as a plurality of layers can be stacked and a crop can be easily dried inside.

The cover 30 covers the drying rack 20 when the heating unit 10 and the drying rack 20 are stacked so that the heat of the heating unit 10 stays inside to smoothly dry the crop .

The cover 30 includes an upper surface 32 covering the upper end of the drying rack 20 and a side surface 34 extending downward from the rim of the upper surface 32 to cover the side surface of the drying rack 20, And a fixing portion (36) for fixing the adjacent side portions (34).

The cover (30) is provided with one or more ventilation windows (31) for communicating outside air. The ventilation window 31 is preferably formed in a mesh shape to prevent foreign matter from penetrating into the ventilation window 31. The ventilation window 31 is preferably provided on one side of the upper surface 32.

The cover 30 is preferably transparent so that the dry state of the crop can be visually recognized and the solar energy is transmitted to improve the drying efficiency. Of course, it is not limited thereto.

The cover 30 is preferably formed of a canvas cloth.

The cover (30) is provided with a ventilation hole (38) communicating with the suction port of the blower (40). The ventilation hole 38 is preferably provided at a lower side of the side portion 34.

The fixing portion 36 fixes the adjacent side portions 34 to seal the inside. The fixing portion 36 is formed of either a Jacquard or a Velcro fastener.

The upper surface 32 is seated on the upper end of the drying table 20 stacked on the uppermost portion of the cover 30 and the side surface portion 34 is drawn along the rim of the drying table 20, 34) is fixed, the inside is sealed.

Further, when the use is completed, the fixing portion 36 is released and the side portions 34 are superimposed on the upper surface 32 and folded for easy storage.

The blower (40) blows air inside the enclosed cover (30) to promote drying of the crop. In addition, it prevents the crop from being corrupted by fresh outside wind.

The blower 40 is installed so that the air inlet is communicated with the ventilation hole 38 of the cover 30 and the air outlet is provided inside the cover 30.

Accordingly, when electricity is applied to the blower 40, external air is introduced into the ventilation hole 38 by the rotational force of the fan provided inside the blower 40, and the air is forcibly exhausted to the exhaust port through the intake port. Also, the forced fresh air is entirely spread in the space enclosed by the cover 30 and is transferred to the upper part and exhausted through the ventilation window 31 provided at one side of the cover 30, Fresh air is circulated inside to prevent crops from decaying.

Particularly, since the air sucked through the blower 40 is heat-exchanged with the heat generated by the heat generating unit 10, the hot air is changed, thereby shortening the drying time by hot air.

A method of drying a crop using the above-configured crop drying apparatus will be described with reference to FIG.

The heat generating section preparation step (S1) is a step of preparing a heat generating section on the paper.

This is achieved by sequentially laminating the heat insulating material 110, the heat reflecting plate 120, and the heat generating sheet 130 on the paper surface to prepare the heat generating portion 10.

Heat exchange between the ground and the heat generating portion 10 is prevented by the heat insulating material 110 and heat emitted from the heat generating portion 130 is reflected upward by the heat reflecting plate 120, Minimize it.

The drying band laminating step S2 is a step of laminating a drying band on the heat generating portion prepared through the heating portion preparation step S1.

This stacks the drying stand 20 on the heat generating portion 10 provided on the ground. The drying rack (20) stores a crop to be dried inside. Further, since the drying stand 20 is formed in a structure in which mutual stacking is easy, even if external vibrations or impacts are applied in a state where a large number of stacks are stacked, they are not easily broken.

Also, the drying stage laminating step (S2) includes a heating sheet addition step (S22) in which a heating sheet is additionally provided between a plurality of drying bases stacked on the heating unit.

This is because, if the height of the plurality of drying rods 20 stacked on the heat generating portion 10 is high, the heat radiated from the heat generating portion 10 can not be smoothly transferred to the upper side, so that a drying imbalance due to a temperature difference may occur To prevent this, a heating sheet 130 is added between a plurality of stacking bases 20 stacked.

Accordingly, the uniform drying of the crop can be achieved as the heat is uniformly distributed regardless of the height of the drying racks 20 stacked by the heating unit 10 and the heating sheet 130.

The cover sealing step S3 is a step of sealing the drying rack with a cover when the stacking of the drying racks is completed in the heating unit through the drying rack stacking step S2.

This is because when the stacking of the drying rack 20 is completed in the heat generating unit 10, the cover 30 closes the drying rack 20 and the heat generating unit 10 so that the heat emitted from the heat generating unit 10 flows to the outside So as to be evenly distributed in the sealed inside without releasing, thereby maintaining a uniform drying state.

That is, after the upper surface 32 of the cover 30 is mounted on the uppermost drying rack 20, the side surfaces 34 extending downwardly from the upper surfaces 32 of the upper surface 32 are lowered, And the side portions are fixed together with the sealing.

In the drying step (S4), when the hermetically sealed drying ladder is closed through the cover closing step (S3), electricity is applied to the heat generating portion to dissipate heat, and the outside air is drawn through the blower to dry .

When electricity is applied to the heat generating sheet 130 of the heat generating unit 10 in a state where the drying stand 20 stacked with the cover 30 is closed, heat is emitted from the heat generating sheet 130. At this time, the heating sheet 130 is provided with a temperature control unit 131, which generates heat by a predetermined temperature through the temperature control unit 131.

The heat of the heat generating sheet 130 is prevented by heat exchange between the heat reflecting sheet 120 and the heat insulating material 110 provided below the heat generating sheet 130 to prevent heat loss.

In addition, power is applied to the blower 40, and hot air flows into the drying rack 20 as the wind flowing through the blower 40 is heat-exchanged by the heat of the heating unit 10.

Therefore, the hot air influences the crop stored in the drying rack 20 by the wind of the heating unit 10 and the blower 40, and is dried through the ventilation window 31 provided at one side of the cover 30, Exhausted.

Through this process, the crop stored in the drying rack 20 is dried.

In the drying device disassembling step S5, when the drying of the crop through the drying step S4 is completed, the dried crops are collected, and then the cover and the heating unit are folded for easy storage.

This is because when the drying of the crop is completed, the cover 30 covering the drying rack 20 is dismantled. That is, when the fixing portion 36 provided on the rim of the cover 30 is unlocked and the neighboring side portions 34 are unfastened, the free side portions 34 can easily be removed from the cover 20 30 can be collected.

Then, the collected cover 30 folds for easy storage.

In addition, the empty drying rack 20 having the storage space is washed and stacked in a predetermined space for the next use.

In addition, the heat generating portion 10 is cleaned and then rolled and stored together with the folded cover 30 when the surface of the heating portion 10 is in contact with the drying table 20.

Therefore, the crop drying apparatus 1 of the present invention can dry the crops in any space, regardless of the limited space.

In addition, it can be folded for easy storage after use.

In another embodiment of the present invention, the ventilation window 31 of the cover 30 is provided with the auxiliary lid 33 as shown in Fig.

The auxiliary lid 33 has a free end whose one end is fixed to the cover 30 and the other end is freely movable. At this time, the free end is provided with an interlocking strap 37 which defines a range of movement.

The auxiliary lid 33 maintains the state of covering the ventilation window 31 to prevent foreign matter from penetrating through the ventilation window 31. When the wind introduced through the ventilation fan 40 is exhausted, The auxiliary lid 33 is pushed up to allow the air to be exhausted.

The blower 40 may also be configured so that one or more small fans are fixed to the side portions 34 of the cover 30, as shown in Fig.

The above description is only one example for carrying out the crop drying apparatus using the heating sheet and the crop drying method using the drying apparatus, and the present invention is not limited to the above-described embodiments. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
