Description

[0001] Apparatus For Drying For Agricultural And Marine Products [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a drying apparatus, and more particularly, to a drying apparatus for agricultural and marine products, which can be easily manufactured based on a conventional refrigeration system, and is excellent in economy and durability.

The agricultural and marine product drying apparatus is widely used as a device for drying the harvested agricultural and marine products until the moisture content reaches the desired value, such as farm houses or agricultural / marine product distribution facilities.

These dryers often have refrigeration cycles. Generally, a refrigeration cycle is a system for continuously circulating refrigerant through four processes of compression, condensation, expansion, and evaporation, and discharges the latent heat of the refrigerating space to the outside air during the evaporation of the refrigerant.

Dryers widely used in conventional farms have been used for refrigeration or freeze storage by controlling the load of the refrigeration cycle and have used the drying function in a way of removing water in the refrigeration or freeze storage process. However, since the ambient temperature is low in winter, it is common to store the refrigeration system without operating the refrigeration system. Therefore, during the winter, equipment was used like a warehouse, and agricultural and marine products kept in storage were left untreated.

1 is a system configuration diagram of a drying apparatus for agricultural and marine products according to an embodiment of the present invention.
Figs. 2 (a), 2 (b) and 2 (c) illustrate flow control means of a drying apparatus for agricultural and marine products according to an embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying FIGS. 1 to 2 (a), (b) and (c).

The loading unit 110 is a shelf mechanism for stacking a large amount of laundry. The loading section 110 is configured so that air can be communicated, respectively. The drying chamber 100 provides a processing space S in which the loading section 110 can be installed. The wall constituting the drying chamber 100 preferably has a heat insulating function. The drying chamber 100 is provided on a scale that can be accessed by the operator. The shape and size of the loading unit 110 and the drying chamber 100 will vary widely and do not limit the scope of the present invention.

A freezing unit is installed around the processing space S of the drying chamber 100. The refrigeration unit performs the process of compressing, condensing, expanding, and evaporating the refrigerant like a normal refrigeration cycle. The freezing unit is for lowering the temperature of the processing space S in the drying chamber 100, and it may be possible to refrigerate and freeze. Hereinafter, the refrigeration unit will be briefly described.

The compressor (1) is for receiving the refrigerant from the evaporator (11) and compressing the refrigerant, and is installed outside the drying chamber (100). The condenser (5) liquefies the high-pressure, high-temperature refrigerant discharged from the compressor (1) by exchanging heat with the outside air. Between the compressor (1) and the condenser (5), a liquid separator (3) for separating oil can be provided. In the description of the present invention, the liquid separator 3 is described by the concept included in the compressor 1. The liquid receiver 7 temporarily stores the high-temperature and high-pressure refrigerant liquid liquefied in the condenser 5 and supplies it to the expansion valve 9. The expansion valve 9 is for reducing pressure by expanding the refrigerant supplied from the receiver 7, and may be installed inside the drying chamber 100. The evaporator 11 installed inside the drying chamber 100 lowers the temperature of the processing space S by exchanging heat with the liquid refrigerant whose pressure has been reduced to a low temperature and a low pressure state while passing through the expansion valve 9. The evaporator (11) absorbs the ambient heat through vaporization of the liquid and supplies the evaporated refrigerant to the compressor (1) to complete the circulation process.

The evaporator 11 is installed at an upper portion of one side of the drying chamber 100 to allow the flow of air as shown by arrow A.

The refrigeration unit described above is a basic configuration of the refrigeration cycle. Therefore, in addition to this, a known additional component such as an accumulator may be installed.

According to the present invention, a reheating unit is included in addition to the freezing unit.

The reheating unit is for supplying coolant in a high-temperature and high-pressure state into the drying chamber 100 to perform heat exchange with the processing space S. The reheat unit serves to lower the relative humidity by raising the temperature of the processing space (S).

The reheat unit includes a reheater (13) installed inside the drying chamber (100). The reheater 13 may have a heat radiating structure for increasing heat exchange efficiency, and may have a fan therein. According to the embodiment of the present invention, the reheater 13 is disposed adjacent to the front of the evaporator 11, that is, on the side of the discharge portion of the evaporator 11 in order to increase the efficiency of reheat.

The outflow pipe 17 for supplying the refrigerant to the reheater 13 is extended in the circulation pipe 19 between the compressor 1 and the condenser 5. The refrigerant that has passed through the reheater 13 is supplied to the receiver through the return pipe 21. The recovery pipe 21 is connected between the reheater 13 and the receiver 7 so that the refrigerant having passed through the reheater 13 is supplied to the receiver 7.

The flow rate control means 15 selectively supplies the high temperature and high pressure refrigerant supplied to the compressor 1 to the reheater 13 or the condenser 5. The reheat unit is started from the beginning only when the reheat unit does not start like the freezing unit and when the reheater unit is in the set state. For example, the control unit controls the flow rate control unit 15 to supply the refrigerant to the reheater 13 when the temperature becomes equal to or higher than the set value based on the temperature of the refrigerant discharged from the compressor 1. [ For example, when the temperature of the refrigerant measured by the thermometer 23 reaches 70 ° C or more, the control unit sends the refrigerant discharged from the compressor 1 to the reheater 13. This temperature corresponds to the temperature at which the refrigeration unit performs the cooling action at normal temperature.

In the case of winter in which the outside temperature is low, the calorific value generated by the freezer may be low and the capacity of the reheater (13) may be insufficient. In this case, the amount of heating heat required by the reheater 13 can be ensured by controlling the flow rate of the indoor unit, that is, the evaporator 11 to induce the high-pressure operation of the compressor 1. [ In addition, the supplementary heater 41 may be installed in the reheater 13 to supplement the insufficient amount of heat.

The flow rate control means 15 can distribute the supplied refrigerant to the reheater 13 or the condenser 5 through various methods. Hereinafter, the flow control means 15 of various methods will be described by way of example.

First, referring to Fig. 2 (a).

The circulation pipe (19) and the take-out pipe (17) are branched by the pipe connector (25). The circulation pipe 19 is a pipe connecting the compressor 1 and the condenser 5. The pipe connection port 25 is a known means of a T (T) type or a W (Y) type.

The first valve 27 which is turned on and off by the control unit is installed in the circulation pipe 19, in particular, in the circulation pipe 19 corresponding to the rear end of the pipe connection port 25. [ And a second valve 29 which is turned on and off by the control unit is installed in the take-out pipe 17. The first and second valves 27 and 29 may be solenoid valves operated on and off by an electrical signal.

According to the present embodiment, the advancing direction of the refrigerant can be selected by opening only one of the valves. In addition, by opening all the first and second valves 27 and 29, the refrigerant can be branched and supplied to the condenser 5 and the reheater 13, respectively.

2 (b).

The circulation pipe (19) includes a plurality of unit circulation pipes (19a, 19b) installed in parallel. The first valve 25 is constituted by a plurality of first unit valves 25a and 25b which are installed separately for each unit circulation pipe 19a and 19b. The unit circulation pipes 19a and 19b and the first unit valves 27a and 27b are each composed of two units.

According to the drawings, the drawing tube 17 may include a plurality of unit drawing tubes 17a and 17b arranged in parallel. The second valve 29 may be constituted by a plurality of second unit valves 29a and 29b, which are provided for each of the unit drawing tubes 17a and 17b and are individually operated. The unit draw-out pipes (17a, 17b) and the second unit valves (29a, 29b) may also be two.

According to the present embodiment, the flow rate can be controlled while selecting the first and second valves 27 and 29 as solenoid valves. This is because all unit valves can be opened to increase the flow rate, or only some unit valves can be opened to lower the flow rate.

The following description will be made with reference to Fig. 2 (c).

According to the present embodiment, the take-out tube 17 is branched and extended from the circulation tube 19 via the three-way valve 31. The three-way valve 31 is a known valve device that allows a flow rate to be selectively supplied in two different directions as one valve. This allows the fluid, that is, the refrigerant, to be supplied only to one pipe. The configuration is simplified, but the selection range of the refrigerant supply method will be reduced.

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
