Description

Agricultural and Marine Product Drying Equipment {AGRICULTURTE AND MARINE PRODUCT DRYING DEVICE}

The present invention uses the dehumidification rotor and the heating medium heater to dry the agricultural and marine products in such a way as to reduce the humidity of the internal air while continuing to circulate the air inside the reservoir containing the agricultural and marine products without directly heating the agricultural and marine products without consumption of the agricultural and marine products without deformation. It relates to an agricultural and marine product drying apparatus that can be dried.

Generally, a device for drying agricultural and marine products comprises a drying chamber in which agricultural and marine products are loaded therein, heating means for heating high temperature dry air to be supplied to the drying chamber, and blowing means for blowing heated hot air into the drying chamber. .

Accordingly, the agricultural and marine products are dried while hot air is circulated through the drying chamber.

In addition, the moisture evaporated from the agricultural and marine products as the drying is exhausted by the increase in pressure in the drying chamber.

The conventional drying apparatus having such a structure has a problem that the amount of fuel consumed is excessively large compared to the drying efficiency because the conventional drying apparatus is a structure for heating and drying the agricultural and marine products in the drying chamber based solely on the fuel burned by the heating means.

However, in recent years, the agricultural and marine products in a semi-dry frozen state are imported into a container in a foreign country and thawed and then completely dried. However, when the agricultural and marine products are directly heated as described above, there is a problem in that the agricultural and marine products are deformed.

In addition, when hot air is supplied to lower the relative humidity, there is a problem that the dried agricultural products are discolored or the taste is reduced.

In addition, in order to dry the agricultural products by the dehumidifier, the refrigerant pressure is about 20 ~ 30Kg / ㎠, but if the dehumidifier stops during operation, it is difficult to restart due to the high pressure, the load is generated in the compressor, the durability is deteriorated There is this.

In order to solve this problem, a plurality of heat exchangers (1) can be installed and the functions of the condenser and the evaporator can be replaced as needed, and a refrigerant circulation system can be smoothly restarted even when high pressure is generated. , "Refrigerant Circulation System and Agricultural Products Dryer Using the Same" (Korean Patent Publication No. 10-2005-0046707) has been published.

The above technique is intended to improve the power consumption and durability is poor due to the large load generated in the compressor 2 in the conventional dryer.

However, despite replacing the condenser and evaporator as described above, there was still a lot of power consumption.

Agricultural and aquatic product drying apparatus of the present invention to solve the problems caused in the prior art as described above, by operating the supply fan while connecting the circulation connection and the supply connection to one side and the other side of the reservoir where the agricultural and marine products are stored air inside the reservoir Continue supplying discharge, but install the dehumidification rotor in the middle to repeat the process of dehumidifying the air discharged from the storage and supply again, in this process by continuously drying the dehumidification rotor using the heating medium heater connected to the heat medium boiler, rather than heat drying The only way to dry the farm is to remove moisture.

At this time, by using a heat medium heater with heat medium oil without using a compressor of a cooling system having a high power consumption is to dry the agricultural and marine products while reducing the power consumption.

In addition, despite the use of a heat medium heater to prevent the deformation of the agricultural and aquatic products by heating only by removing the moisture without drying the agricultural and aquatic products.

Here, the method of supplying the heat medium oil to the heat medium heater 51 is provided with a separate heat medium boiler is connected to the heat medium oil supply pipe 53 and the heat medium oil discharge pipe 52 in the heat medium boiler, the heat medium in the heat medium heater 51 By connecting the oil supply pipe 53 and the heat medium oil discharge pipe 52, the heat medium oil heated by the heat medium heater 51 may circulate the heat medium heater 51.

By using the heat medium boiler and the heat medium heater (51) it is good to ensure that the high temperature heat medium oil of 140 ~ 180 ℃ to the heat medium heater (51).

As the high temperature heat medium oil circulates through the heat medium heater 51, the outside air introduced from the outside is heated, and the heated air heats the dehumidification rotor 30 while drying the dehumidification rotor 30, thereby dehumidifying rotor ( 30) will continue to absorb moisture.

Meanwhile, instead of using the heat medium heater 51, a hot water heater may be used. The hot water boilers, gas boilers, and electric boilers in individual houses, such as hot water at 60-90 ° C supplied by district heating or gas corporations, or the like, may be used. The hot water generated may be supplied, but the efficiency is somewhat lowered because it is lower than the heat medium heater 51.

To this end, the structure of the heat medium heater 51 may be configured by installing an aluminum fin of about 6 to 12 sheets per inch on the copper coil or installing a fin on a coil made of a material such as copper, aluminum, or stainless steel.

In addition, as the air of the supply connecting portion 80 is supplied to the reservoir 90 by the operation of the supply fan 81, the humid air inside the reservoir 90 is introduced through the circulation connection portion 10, and the air is dehumidified. Passing through the sieve heat exchanger 60 is dehydrated while passing through the rotor 30 is supplied into the reservoir 90 via the supply connection portion 80.

As the air dried by the dehumidification rotor 30 continues to be supplied to the storage 90, the agricultural and marine products inside the storage 90 are finally dried.
