Description

[0001] Drying device for agriculture and stock farming [

More particularly, the present invention relates to a drying apparatus for agricultural and marine life and, more particularly, to a method of drying a agricultural and horticultural product through a microwave generator, drying the agricultural and horticultural product by a radial heat generated from a surface heating element, The present invention relates to a drying apparatus for agricultural and marine life, which is capable of drying high-temperature and high-humidity air by using a dehumidifying filter to lower humidity and then drying it to reduce the energy consumption.

Generally, it is most preferable that the crops such as red pepper, high-priced medicinal materials and herbal medicines, or aquatic products such as dried fish, fish and seaweed are dried by natural wind and solar heat, but the contamination due to unsanitary substances such as dust and foreign matter, And since it takes a long time to dry, it is unsuitable to dry in a large amount, so that a large amount of crops are usually dried in a limited space using a dryer.

Accordingly, various types of dryers for drying agricultural and marine life and stockyards have been proposed. Most of the dryers using hot air have a structure for forcedly circulating warm air. Examples of such hot air circulating dryers are Korean Utility Model Application No. 20-2006-0000503 There is a "Agricultural and Marine Products Dryer".

The warm air circulation type dryer is configured to heat the air with the moisture evaporated from the crops in a closed space for drying the crops to a high temperature to raise the temperature only in a high humidity state, .

That is, in the conventional dryer, there is a possibility that the crops are damaged by applying heat of high temperature to the crops, and the drying time is long by circulating the water evaporated from the crops without discharging them to the outside.

In addition, since such a dryer needs to be divided into a small amount of laundry using a shelf located in the inside of the dryer and transferred to a drying room, considering the fact that the rural area occupies the majority of the elderly population, There is a problem that the operation is cumbersome and inconvenient to use.

1 to 6, the drying apparatus for agricultural and marrow-shrimp according to the present invention is characterized in that a door 110 is installed at a front part, a side panel 130 and a rear panel 140 are composed of a loess panel, 150 are provided with a housing 100 having an area heating element.

In addition, a microwave generator 101 is provided at one side of the inside of the housing 100 to primarily dry the agricultural and fishery stock, and the surface heating element is provided, and the agricultural and horticultural products are secondarily dried by the radiant heat.

In addition, the side panel 130 or the front panel is provided with a see-through window 131, and the operator observes the agricultural and marine products that are dried inside the housing 100. Although not shown in the drawing, the front panel is composed of doors and may be provided with a front panel when the size of the door is small.

Further, an intake tube 121 through which the air used in the drying operation flows is provided at one side of the upper panel 120. In addition, an intake valve 122 is provided in the middle of the intake pipe 121 to control the opening and closing of the intake pipe 121. Here, the intake pipe 121 is installed at the uppermost part of the lower part of the bypass pipe 300, which will be described later, so that the cold air introduced into the intake pipe 121 descends to the lower part, Increase.

The housing 100 includes a plurality of frames 160 coupled to an inner edge region thereof, a guide 161 fixed to each of the frames 160 and the guide 161, And a drying plate 162 on which a plurality of through holes are formed. Accordingly, the drying operation is performed while the agricultural and horticultural products are placed on the drying plate 162.

On the other hand, a dehumidifying filter (301) communicating with the upper and lower portions of the housing (100) and positioned in the middle, a second opening / closing valve (302) provided in front of the dehumidifying filter (301) And a fan 303 positioned in front of the bypass pipe 302. The bypass pipe 300 sucks hot and humid air from the lower part of the housing 100 by using the fan 303 to remove moisture from the dehumidifying filter 301 to make hot and humid air, (Not shown). In addition, a fan (not shown) is further coupled to the upper coupling portion of the bypass pipe 300 and the housing 100 so that the high temperature and low-humidity air flowing out of the bypass pipe 300 is directed toward the inside of the housing 100 It may also flow smoothly.

Further, a heater (not shown) may be further provided in front of or behind the dehumidifying filter 301. The heat is applied to the air to be removed or removed due to the heater, so that the dehumidifying efficiency and the drying efficiency can be further increased.

A discharge pipe 200 having a first opening / closing valve 201 at an intermediate portion thereof is connected to an intermediate portion of the bypass pipe 300 so that moisture generated by the microwave 101 is discharged to the outside air. Specifically, a discharge pipe 200 is provided between the second on-off valve 302 and the fan 303. This is because the first on-off valve 201 must be closed and opened by opening and closing the second on-off valve 302, so that a discharge pipe 200 is provided below the second on-

In addition, a humidity sensor 305 is provided in a region close to the housing 100, which is in front of the bypass pipe 300. Accordingly, the humidity of the air discharged through the bypass pipe 300 is sensed. For reference, the front and rear directions in this specification are based on the direction of air flow.

In the meantime, the housing 100 is firstly dried through the microwave generator 101 through the microwave generator 101, and sucks moisture generated inside the housing 100 and discharges the moisture to the outside. Further, the drying efficiency A vacuum pump 400 may be further provided. The vacuum pump 400 may be connected to the bypass pipe 300 or may be installed separately from the bypass pipe 300 as shown in FIG. A valve (not shown) must be installed in front of the vacuum pump 400.

Although the exhaust pipe 200, the bypass pipe 300 and the vacuum pump 400 are illustrated in the rear panel 140 in the drawing, they can be installed in all areas except the bottom of the housing 100 . Accordingly, they may be provided on the rear panel 140, the lower panel 150, and the upper panel 120, except for the lower panel 150.

On the other hand, the humidity sensor 305, the first and second open / close valves 201 and 302 are not specifically shown in the drawing, but are controlled by a control unit. Specific operations will be described later.

On the other hand, the clay panel constituting the side panels 130 and the rear panel 140 is formed by sequentially arranging the finishing material 401, the glass fiber 402, the surface heating element 403 and the clayey layer 404 from the outermost side It is preferable to be laminated.

60 wt% of a raw material mixed with 90 wt% of the loess powder and 10 wt% of an additive powder made of ceramic powder, anion powder, jade powder, and elvan powder is mixed with 60 wt% of alginic acid, gypsum, , 30% by weight of an adhesive composed of any one of cut pieces of rice straw and 10% by weight of an admixture composed of a foaming agent for 100 hours to 200 hours for 3 to 5 hours.

This is because moisture generated during the drying operation inside the housing 100 is discharged through the discharge pipe 200, but a part of the moisture is absorbed into the clay soil layer 404. The moisture absorbed into the clay soil layer 404 is evaporated by the exothermic reaction of the surface heat emission element 403. [

The planar heating element 403 is a carbon fiber heating element and is electrically connected to an external power source to cause an exothermic reaction.

In addition, the glass fiber 402 prevents the heat generated in the surface heat emission element 403 from being transmitted to the outside, thereby preventing the finish material 401 from rising to a high temperature.

As described above, the fired yellow soil panel remains in a hardened state and is not damaged even if it is handled normally.

However, in the case of the above-described loess panel, when the firing temperature is increased to 100 to 200 or more and fired at a higher temperature, the fired heat generating element 403 may be deformed or broken, so that it is most desirable to sinter for 3-5 hours at 100-200 The panel can be obtained.

The above-described loess layer 404 is composed of silicon dioxide, aluminum oxide, iron powder, magnesium, sodium, and carly, and is composed of various enzymes, and emits far-infrared rays and negative ions when drying agricultural and marine products.

Particularly, it plays an role of suppressing the growth of bacteria such as fungi by excellent energy saving, heat insulation effect and humidity control ability due to heat storage action, excellent smell by excellent adsorption power, and excellent antibacterial property.

In the case of the above-mentioned clayey sole layer 404, a through hole or an uneven surface can be formed to increase the water absorption area. This can be selectively formed depending on the size of the drying apparatus installed.

On the other hand, if the lower panel 150 is composed of a loess panel, the moisture generated when drying the agricultural and fishery stocks may fall to the bottom and the loess panel may be damaged. And it is possible to efficiently dry the agricultural and marine life and shale by constructing it with only the loess panel.

In addition, even when the drying apparatus is driven, unexpected power failure or disconnection occurs, the inside of the housing 100 is already formed at a high temperature. Since the loess panel absorbs such high temperature heat, Can be smoothly dried.

In addition to the structure of the frame 160 and the guide 161, a plurality of conveying conveyors 170 having a belt 171 on the outer side as shown in FIG. 5 may be provided inside the housing 100 .

The conveying conveyor 170 is operated to move the belt 171 by a predetermined length so that the aggregate of the belt 171 is conveyed to the entire area of the belt 171 It will put it on dry.

3 and 4, the frame 160 and the guide 161 are used for a relatively small-sized housing. In the case of a relatively large-sized housing, a structure similar to that of FIG. 5 is adopted and used .

Hereinafter, the operation state of the apparatus for drying agricultural products and water and the method of drying the agricultural and horticultural products will be described.

The operator first places the object to be dried on the drying plate 162 or the belt 171 and then closes the door 100 by closing the door 110 and drives the microwave generator 101. At the same time, the fan (303) is also driven and the humid air generated inside the housing (100) is discharged to the outside through the lower area of the bypass pipe (300) and the discharge pipe (200). At this time, the first on-off valve 201 is opened and the second on-off valve 302 is closed. At this time, the intake valve 122 is opened to allow the outside air to flow into the housing 100.

The humidity sensor 305 of the discharge pipe 200 senses the humidity of the inside of the housing 100 to operate the control unit and the first opening and closing valve 201 The second open / close valve 302 is opened, and the hot air is moved back to the inside of the housing 100 through the bypass pipe 300.

At the same time, the driving of the microwave generator 101 is stopped, and the planar heating elements provided on the side surface, the rear surface, and the lower panel are driven.

At this time, the water passes through the dehumidifying filter 301 installed in the middle part of the bypass pipe 300, and once again the moisture is removed and moved to the inside of the housing 100. At the same time, the intake valve 122 is also closed so that high-temperature air flowing into the bypass pipe 300 flows into the housing 100.

As a result, the low temperature and low humidity air circulates back to the inside of the housing 100, so that the time and energy for warming the air by the surface heating elements can be reduced, and energy can be saved.

The dehumidification of the moisture by the microwave generator 101 only at a temperature of about 40 to 50% and then the driving is stopped and the surface heating element is operated because the dehydration using only the microwave generator 101 can burn down the agricultural and marine life The drying of the agricultural and horticultural products is firstly performed through the microwave generator 101, and then the agricultural and horticultural products are gradually dried through the surface heating element to obtain a better quality dried material.

Also, when the drying by the surface heating element is carried out first, the humidity becomes too high, and the drying ability may be lowered due to the excessive load on the dehumidifying filter. Therefore, as in the present invention, primary drying is performed using a microwave, Tea drying is important.
