Description

[0001] The present invention relates to a dehumidifier for drying agricultural products,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehumidifying device for an agricultural product dryer, and more particularly, to a dehumidifying device for an agricultural product dryer, in which hot air is supplied into a drying chamber to dry agricultural products by hot air, The present invention relates to a dehumidifying device for a dryer for agricultural products, which removes moisture contained in air and recycles the moisture-depleted high-temperature internal air into the drying chamber to minimize the amount of humidity remaining in the drying chamber while minimizing the loss of internal air at a high temperature.

Generally, there are various types of drying methods such as hot air drying, cold air drying and freeze drying, for drying agricultural and marine products.

Among them, the hot-air drying method, which is mostly used in a farm, is a method of continuously supplying 50-80 ° C hot air to the agricultural products loaded in the drying chamber of the dryer to evaporate a large amount of water contained in the agricultural products to dry the agricultural products .

The hot air drying method as described above can be relatively easily used to dry the laundry so that it can be utilized in the farmhouse. However, due to moisture generated in the drying process of the agricultural products, the inside air of the drying chamber forms a high temperature and high humidity.

Accordingly, in the art, an exhaust port communicating with the outside is formed in the drying chamber to open the exhaust port during the drying process of the agricultural product through the hot air to release the air containing moisture into the atmosphere, and the process of re- .

However, if the inside air in the high temperature and high humidity state remaining in the drying chamber is exhausted to the outside and the external air in the room temperature state is reheated, the heat loss of the drying chamber increases, and due to the impurities due to the continuous inflow of outside air, This contamination problem can be caused.

In order to solve this problem, dehumidifying devices have been developed which remove moisture from the hot and humid air remaining in the drying chamber.

Korean Patent Registration No. 10-1071808 discloses a dryer main body having a drying chamber and a machine room separated from each other. In the dryer main body, an air inlet is formed in a lower portion between the drying chamber and the machine room, The air introduced into the lower portion of the drying chamber is discharged to the upper portion via the drying chamber, and then the air circulated through the machine room is introduced again into the lower portion of the drying chamber.

A compressor installed in the interior of the machine room for compressing the refrigerant; a condenser installed in the middle of the machine room for condensing the refrigerant and being connected to the compressor to exchange heat with the heated air through the following reheater, A condenser for heating the condenser; an air blower installed on the air inlet side of the machine room for sending the air heated by the condenser to the inside of the drying chamber; and a condenser installed on the air outlet side of the machine room, An evaporator connected to the compressor to evaporate the expanded refrigerant and to dehumidify the air through heat exchange with the air discharged from the drying chamber and a condenser and an evaporator disposed in parallel with the evaporator, And includes a reheater to heat the cold air through the evaporator through heat exchange with the air Dehumidifying dryer for agricultural products comprising suggests.

When the air discharged from the drying chamber is exchanged through the evaporator using the refrigeration cycle, the humidity of the air contained in the air is rapidly condensed, and the efficiency of drying the agricultural product through the dryer is secured.

However, since the refrigeration cycle consumes a large amount of current in the process of continuously compressing and condensing the refrigerant, it is burdensome to use in the farmhouse, and the expensive facility cost is generated. Therefore, I am reluctant.

Accordingly, in this field, it is required to develop and supply a simplified dehumidifying device capable of installing at low cost, condensing the air discharged from the drying chamber, and removing a large amount of moisture remaining in the air.

The dehumidifying units 30, 40, and 50, which remove moisture and supply the moisture to the exhaust unit 20 from the internal air of high temperature and high humidity introduced through the intake unit 10, 41a and 51a communicating with the intake unit 10 and exhausting passages 31b 41b and 51b communicating with the exhaust unit 20 are formed as shown in FIG. 41, and 51 that are disposed in the dehumidification chambers 31, 41, and 51, respectively, and in which the inside of the dehumidification chambers 31, 41, And a dehumidifier (32, 42, 52) for dehumidifying the air by condensing the moisture.

Dehumidifying space portions (33, 43, 53) are formed between the inner walls of the dehumidifying chambers (31, 41, 51) and the dehumidifier (32, 42, 52)

As will be described later, the dehumidifiers 32 and 42 according to the first embodiment and the second embodiment of the present invention circulate cooling water, which is supplied through the supply pipe P1 and recovered through the recovery pipe P2, The cooling water is continuously cooled by the circulating cooling water, and the cooling water is supplied at a constant temperature at all times, so that it is preferable to use ground water which does not require any additional cooling.

Therefore, the high temperature and high humidity internal air circulated through the dehumidifying space portions 33, 43 and 53 through the intake passages 31a, 41a and 51a is cooled by heat exchange with the cooling water, The dehumidified internal air is brought into contact with the surfaces of the dehumidifiers 32, 42 and 53 to condense moisture on the surfaces of the condensers 32 and 42 to form condensed water. Is re-introduced into the drying chamber (110) of the dryer (100) and the crops are dried.

In the first embodiment of the present invention, as shown in Fig. 2 to Fig. 4, the cooling block 32a in which the cooling water circulation conduit 32b circulating the cooling water circulates is disposed in the dehumidification chambers 31 and 41 Block type dehumidifying part 30 in which the surface of the cold block 32a is cooled by heat exchange with the cooling water circulating inside along the cooling water circulation pipe 32b.

As shown in FIG. 2, a plurality of cooling water circulation conduits 32b are vertically arranged in parallel to the cooling block 42a. The cooling water supplied through the water supply pipe to the upper end of the cooling water circulation conduit 32b is circulated through the cooling water circulation conduit And a water supply manifold 32c for collectively supplying cooling water circulating through each of the cooling water circulation ducts 32b is disposed at the lower end of the cooling water circulation duct 32b, And a collecting manifold 32d for discharging the collected water.

With this configuration, the cooling water circulation ducts 32b are collectively supplied with the cooling water through the water supply pipe, and consequently, the cooling block 32a can be uniformly and rapidly cooled.

Therefore, the internal air passing through the dehumidifying space portion 33 formed between the dehumidification chamber 31 and the dehumidifier 32 is cooled by the heat exchange with the cooling water as shown in FIGS. 2 to 4, Condensed on the surface of the cooling block 32a while being condensed on the surface of the cooling block 32a and condensed on the surface of the cooling block 32a is dropped through the drain hole 31c formed in the lower portion and discharged.

In the second embodiment of the present invention, as shown in Figs. 5 to 7, the forced air is forcedly circulated in the form of vortex through the intake unit 10 to primarily centrifuge the water contained in the inside air And then dehumidifying the dehumidified air by condensing moisture remaining in the air by contact with the surface of the dehumidifier 42 whose surface has been cooled.

The cyclone type dehumidifier 40 includes a cone type cyclone dehumidification chamber 41 having an intake passage 41a formed at one side of the upper portion thereof, an exhaust passage 41b formed at an upper portion thereof, and a drainage hole 41c formed at the lower portion thereof. .

The dehumidifier 42 disposed in the cyclone dehumidification chamber 41 includes a spiral tubular body wound with a spiral structure of the cooling water circulation pipe 42a. The dehumidifier 42, which is formed of the spiral tubular body, The exhaust port 41b and the hollow portion of the dehumidifier 42 are vertically communicated with each other.

Therefore, the internal air introduced into the dehumidification chamber 41 along the intake path 41a is circulated in the form of a vortex in the form of a vortex, and then discharged through the exhaust path 41b formed in the upper part. The water contained in the internal air is centrifugally separated and discharged through the drain port 41c formed in the lower portion.

Thereafter, the internal air, which is primarily dehumidified by the centrifugal separation, is moved to the exhaust path 41b formed on the upper part, while contacting the surface of the cooled dehumidifier 42 composed of the helical tubular body, And condensed water, thereby discharging the condensed water in which residual moisture has condensed through the drain hole 41c formed in the lower part.

Particularly, the dehumidifier 42 has a tubular shape by winding the cooling water circulation pipe 42a in a spiral shape. The inner air that has been primarily dehumidified by centrifugal separation rises along the inner wall of the spiral dehumidifier, The condensed water condensed on the inner wall of the dehumidifier 42 falls down to be discharged.

Thus, the moisture contained in the internal air is primarily dehumidified by centrifugal separation through air circulation, and the secondary dehumidification is performed by condensation by contact with the water-cooled dehumidifier 42, The condensed water generated by the condenser is finally drained through the drain hole 41c formed at the lower part.

In this embodiment, a screen 41d is provided in the drain port 41c in the cyclone dehumidification chamber 41 and a dehumidifying space 43 formed in the cyclone dehumidification chamber 41 is provided with one or more floating impact balls 46 The flotation balls 46 are blown to the inner wall of the dehumidifying chamber 41 and the dehumidifier 43 in a floating state in the dehumidifying space part 43 by the air circulating through the dehumidifying space part 43, So that the condensed water remaining on the inner wall of the dehumidification chamber 41 and the surface of the dehumidifier 43 is rapidly drained to the drain port 41a formed at the lower portion.

8, a dehumidifying block 52d that is cooled by the electronic cooler 52 is disposed in the dehumidifying space portion 53 formed in the dehumidification chamber 51, The internal air introduced into the dehumidifying space portion 53 through the dehumidifying space 51a through the dehumidifying space portion 51a is condensed by the dehumidification block 52d cooled by the electronic cooler 52, A dehumidifying part 50 is proposed.

The electronic cooler 52 includes a Peltier element in which a cooling surface 52a is formed on one side by a current applied from a control module and a heat dissipation surface 52b is formed on a back side; And a heat dissipating piece 52c disposed on the heat dissipating surface 52b of the Peltier element and discharging heat radiated from the heat dissipating surface 52b to the outside.

The heat dissipating piece 52c and the heat dissipating fan 52d for cooling the heat dissipating surface 52b are added to the heat dissipating piece 52c so that the heat dissipating surface 52b formed in the Peltier device can be quickly Allow to cool.

In the present embodiment, the dehumidifying block 52d is hollow, and the cooling water is filled in the hollow portion 52d-a of the dehumidifying block 52d to contact the dehumidifying block 52d Is instantaneously heated so that the dehumidification efficiency is prevented from being lowered and the overload of the pellicle element due to the direct contact of the high temperature internal air to the cooling surface 52a of the Peltier element is prevented.

That is, in the present invention, the cooling water charged in the dehumidifying block 52d is continuously cooled through the cooling surface 52a of the Peltier element, and then the dehumidifying block 52d in which the cooled cooling water is filled and the high- Thereby condensing the moisture remaining in the internal air and discharging it.

For example, the cooling surface 52a of the Peltier element emits cool air of 0 to 1 占 폚 to continuously cool the cooling water charged in the cooling block, and the cooling block 52d and the hollow portion 52d- Let the temperature of the cooling water charged in a) fall below the set value.

At this time, the control module (not shown) measures the temperature of the cooling water through the temperature measuring sensor 56 disposed in the dehumidifying block 52d. When the temperature value of the measured cooling water falls below the set value, And the exhaust blower 21 are driven to circulate and discharge the hot and humid air remaining in the drying chamber 110 in the dehumidifying space portion 53 to condense the moisture remaining in the inside air to dehumidify.

Then, when the temperature of the cooling water charged into the dehumidifying block 52d by the heat exchange with the inside air rises above the set value, the control module temporarily stops the driving of the air intake blower 11 and the exhaust blower 21, The cooling water heated through the cool air emitted from the cooling surface 52a of the Peltier element is cooled to a set temperature value or lower and the intake blower 11 and the exhaust blower 21 are driven again when the cooling water is cooled to a set temperature value or lower , The humid air remaining in the drying chamber (110) is circulated and discharged in the dehumidifying space (53), and the moisture remaining in the inside air is condensed and dehumidified.

With this configuration, the cooling water charged into the dehumidifying block 52d and the dehumidifying block 52d is heated at a high temperature by heat exchange with the inside air, thereby preventing damage to the Peltier element due to overload of the Peltier element.

In addition, the intake air blower 11 and the exhaust blower 21 are driven only when the cooling water is kept at the set temperature value or lower and the moisture can be condensed, thereby dehumidifying the high temperature and high humidity internal air required for dehumidification, Unnecessary driving of the exhaust blower (11) and the exhaust blower (21) is prevented.

On the other hand, the dehumidifying portions 30, 40 and 50 of the dehumidifying device 1 for a produce dryer according to the present invention are characterized in that the surfaces of the dehumidifiers 32, 42 and 52 cooled by the heat exchange action with cooling water or cold air, The inside air forced in the drying chamber 110 is contacted to condense the moisture remaining in the inside air and discharge the moisture.

Therefore, condensed condensed water remains on the surfaces of the dehumidifiers 32, 42 and 52. The condensed water condensed on the surfaces of the dehumidifiers 32, 42 and 52 must be drained quickly, It is possible.

For example, if the condensed water condensed on the surfaces of the dehumidifiers 32, 42, 52 is not quickly drained, the condensed water is evaporated by the hot and humid air circulating along the dehumidifying space portions 33, 43, 53 , And the evaporated moisture may be re-introduced into the drying chamber 110 through the exhaust part 20.

In order to solve this problem, in the present embodiment, as shown in FIG. 2 to FIG. 8, air is blown onto the surface of the dehumidifier 32, 42, 52, on which the condensed water is condensed, , Thereby forming one or more spray nozzle units (34, 44, 54d) for forcibly discharging the condensed condensed water to the surface of the dehumidifier (32, 42, 52d).

According to the present embodiment, the injection nozzle units 34, 44, and 54 may be configured to discharge air supplied from a separate air supply source such as an air compressor downwardly, which is also within the scope of the present invention .

In this embodiment, some of the internal air forcedly introduced into the dehumidifying units 30, 40, 50 through the intake unit 10 is distributed to the intake passages 31a, 41a, 51a, 45 and 55 are distributed to the spray nozzles 34, 44 and 54. The injection nozzle units 34, 44 and 54 are connected to the distributing pipes 35, 45 and 55, 42, and 52 in the downward direction along the surfaces of the dehumidifiers 32, 42, and 52, respectively.

The injection nozzle units 34, 44, and 54 may be configured to always spray air downward on the surfaces of the dehumidifiers 32, 42, and 52d.

When the air is always sprayed on the surfaces of the dehumidifiers 32 and 42, contact between the inside air introduced into the dehumidifying space portions 33 and 43 and the surfaces of the dehumidifiers 32 and 42 is interrupted, Condensation efficiency of moisture may be lowered.

In consideration of this, in the present embodiment, air is not always sprayed onto the surface of the dehumidifier 32, 42, 52d at all times, and the air is sprayed intermittently through the open / close valves 34a, 44a, 54a The condensed water condensed on the surface of the dehumidifier 32, 42, 52d is discharged to the surface of the dehumidifier 32, 42, 52d by spraying air downward onto the surface of the dehumidifier 32, 42, Are discharged to the lower part where the drain ports (31c, 41c, 51c) are formed.

For this purpose, in the present embodiment, open / close valves 34a, 44a, 54a for opening and closing the spray holes are disposed in the spray nozzle units 34, 44, 54 by a control signal, and the dehumidifiers 32, 42, A moisture sensor (34b, 44b, 54b) for sensing the condensed water remaining on the surface of the dehumidifier is provided.

Accordingly, the control module (not shown) senses the condensed water on the surfaces of the dehumidifiers 32, 42, 52d by the moisture sensors 34b, 44b, 54b, 45 and 55 through the first and the second exhaust pipes 54a and 54a to drain the condensed water remaining on the surfaces of the dehumidifiers 32, 42 and 52d downward.

Thus, the internal air introduced into the dehumidifying space portions 33, 43 and 53 is normally cooled by contact with the surfaces of the cooled dehumidifiers 32, 42 and 52d to achieve stable condensation, The condensed water remaining on the surfaces of the dehumidifiers 32, 42 and 52d is discharged downward through the spray nozzle units 34, 44 and 54 when the residual amount of the condensed water is detected on the surfaces of the dehumidifiers 32, And is forced to be discharged to the lower part.
