JP3078262U - Multifunctional cold air dryer - Google Patents

Abstract

(57) [Summary] [PROBLEMS] To manufacture an apparatus having a function of cold air drying, freezing and thawing of food using the same apparatus.
From the following, the air conditioning range is expanded to + 30 ° C to enable cold air drying, freezing and thawing operations.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs] Freezing, cooling and drying of food

[0002]

2. Description of the Related Art Conventional cold air drying equipment has functions of drying and thawing, and the function of freezing equipment is freezing and thawing. Therefore, two processors are required for processors who need cold air drying and freezing equipment.

[0003]

[Problems to be Solved by the Invention] An apparatus having a function of cold air drying, freezing and thawing of food with the same apparatus is manufactured.

[0004]

The conventional cold air dryer has a temperature range of -0.5.degree. C. to + 30.degree. C., and cannot operate in the freezing region required for freezing since it is from the refrigerated region to the air-conditioned region. Therefore, to cope with the operation of the evaporator in the freezing area, the fine pitch was increased to 7 mm or more (conventionally around 4 mm). Expand to + 30 ° C to enable freezing operation.

[0005]

[Embodiment of the invention]

 1 Drying operation Each unit is put into an operating state, and the moisture in the drying cabinet 1 is condensed by the evaporator 9 and dehumidified and dried, thereby promoting the drying of the food provided in the differential pressure unit 2. The temperature in the refrigerator is maintained by sending the gas discharged from the refrigerator 5 to the first condenser 6 and the second condenser 10 by the switching valve 16.17 by the temperature controller. 2 Freezing operation Each unit is put into an operation state, and the temperature in the drying cabinet 1 is lowered to the freezing region by the evaporator 9 to freeze the food. The temperature in the refrigerator is controlled by opening / closing the refrigerant liquid solenoid valve 14 (pump down method) by the temperature controller to start and stop the refrigerator 5. During this operation, the switching valve 16 is open and 17 is closed. Defrosting of the evaporator 9 is performed by the electric heater 11 as appropriate. 3 Thawing operation The refrigerator unit 4 is stopped, the other units are put into operation, and the electric heater 11 (also used for defrosting) is energized to raise the temperature inside the drying cabinet to a temperature above the freezing point of the food. The temperature inside the refrigerator is adjusted by opening and closing the electromagnetic switch for the electric heater 11 using a temperature controller.

[0006]

[Effects of the Invention] Reduction of equipment costs by unifying equipment and the shift from dry operation to freezing operation without moving food, leading to a reduction in labor.
