The refrigeration systems such as air conditioners generally have a refrigeration mode and a dehumidification mode, when the refrigeration system adopts the refrigeration mode, the temperature is a control reference factor, the compressor stops working after the set temperature is reached, the indoor humidity is not taken as the control reference factor, efficient dehumidification cannot be achieved, when the refrigeration system adopts the dehumidification mode, the indoor humidity is the control reference factor, as long as the indoor humidity does not reach the set target, the compressor can act all the time, the indoor air temperature is lowered continuously at the moment, the food moisture evaporation efficiency is also lowered continuously, although the air humidity can possibly reach the target set value, the moisture in the food can not be volatilized, and therefore, the efficient air drying of food materials cannot be achieved by the existing refrigeration system. The existing refrigerating system also has the temperature of controlling cold air by controlling the power of a compressor, the flow rate of a refrigerant and other modes, and the modes form a temperature control curve, however, because the air drying processes of different foods are different, the air drying temperatures are also different, and the specific heat capacities of different foods are different, so the cabinet body 100 placed with different foods substantially forms different heat systems, the temperature control curve of the refrigerating system is different, and the temperature of the refrigerating system is more difficult to control the cold air. In a word, the existing refrigerating systems are controlled based on the purpose of refrigeration or dehumidification, and other factors are not needed to be considered, so that the existing refrigerating systems are difficult to meet the requirements of food air drying processes and are not suitable for food air drying.

The controller 300 may control the operation of the air dryer according to the food process, so that the air dryer has multiple functions, for example, starting the refrigeration cycle may cool and dehumidify the air to dry the food, or may freeze and preserve the food, and starting the dehumidification cycle may reduce the humidity of the air in the air drying chamber 110; when the dehumidification circulation loop works, the air in the air drying cavity 110 is firstly cooled and dehumidified by the second evaporator 260 and then heated and heated by the first evaporator 250, the work of the compressor 210 and the like is controlled by the controller 300, so that the temperature of the air after passing through the first evaporator 250 is slightly higher than that of the air before passing through the second evaporator 260, and under the control of the controller 300, when the temperature in the air drying cavity 110 is higher than a first set temperature, the refrigeration circulation is started to cool and dehumidify the air in the air drying cavity 110, and when the temperature of the air is lower than a second set temperature, the refrigeration circulation is closed, and the dehumidification circulation loop is started to dehumidify the air and gradually increase the temperature. Therefore, through the matching of the refrigeration circulation loop and the dehumidification circulation loop, on one hand, cold air drying can be continuously carried out on food, the humidity of air in the air drying cavity 110 is reduced, the temperature of the air in the air drying cavity 110 is maintained within a second set temperature and a first set temperature, the cold air is uniform, the efficiency of water evaporation of the food is ensured, and the air drying time is effectively shortened; the air-drying cavity 110 forms a closed internal environment, which can effectively prevent external impurities, germs and the like from entering the installation cavity 130, and ensure that the sanitary conditions of the food meet the standards.

Referring to fig. 4, it can be understood that in some embodiments, one condenser 220, one filter drier 230, and one throttling mechanism 240 are provided, a refrigerant inlet of the first evaporator 250 is connected to an air outlet of the compressor 210, and a refrigerant outlet of the first evaporator 250 is connected to a refrigerant inlet of the condenser 220, so that the condenser 220, the filter drier 230, and the throttling mechanism 240 are shared by the dehumidification cycle loop and the refrigeration cycle loop, on one hand, the structure of the air dryer group can be simplified, and the cost can be reduced, and on the other hand, the dehumidification cycle loop and the refrigeration cycle loop can be switched conveniently and quickly.

When the refrigeration cycle loop works, the air in the air drying cavity 110 is cooled and dehumidified when passing through the second evaporator 260, and then the dry cold air enters the air drying cavity 110 again to dry the food, and the temperature in the air drying cavity 110 is continuously reduced.

Referring to fig. 4, it can be appreciated that in some embodiments, the specific operation of the dehumidification cycle is as follows: the second electromagnetic valve 272 is opened, and the first electromagnetic valve 271 and the third electromagnetic valve 273 are closed, so that the high-temperature and high-pressure refrigerant gas discharged from the air outlet of the compressor 210 firstly enters the first evaporator 250 to release part of heat to heat the air, then enters the condenser 220 to be changed into high-pressure and low-temperature refrigerant liquid, the high-pressure and low-temperature refrigerant liquid passes through the drying filter 230 and the throttling mechanism 240 to be changed into supercooled refrigerant liquid, then enters the second evaporator 260 of the evaporator to be evaporated to absorb heat of the air, and finally returns to the compressor 210 to be recompressed, thereby completing the dehumidification cycle. When the dehumidification cycle loop works, the air in the air drying cavity 110 firstly flows through the second evaporator 260 to be cooled and dehumidified, then flows through the first evaporator 250 to be heated and heated, and finally enters the air drying cavity 110 again to dry food, the controller 300 can enable the heat released by the first evaporator 250 to the air to be slightly more than the heat absorbed by the second evaporator 260 by controlling the compressor 210, the flow rate of the refrigerant and the like, and further enable the temperature of the air when the air enters the air drying cavity 110 again to be slightly higher than the temperature before passing through the second evaporator, so that the temperature of the air in the air drying cavity 110 is gradually increased.

The operating parameters may include time, temperature, etc. Through the method, the utility model provides a food air-dry cabinet system can carry out air-dry work according to the requirement of different food air-dry technologies, guarantees the quality and the flavor of food.

It is understood that, in some embodiments, the above-mentioned operation mode may include a cool air drying mode, and the cool air drying mode may be: when the food needs to be air-dried, if the temperature in the air cavity 110 is higher than the first set temperature, the refrigeration cycle loop works and the fan assembly 280 works under the control of the controller 300, if the temperature in the air cavity 110 is lower than the second set temperature, the refrigeration cycle loop stops working and the dehumidification cycle loop starts working under the control of the controller 300.

It can be understood that, when the air is dried in the hot air, the power of the dehumidification circulation loop for heating the air is insufficient due to the set temperature, so that the heating device 400 can be used for assisting heating, so that the air returned to the air drying chamber 110 again maintains a certain temperature. When hot air drying is carried out, the temperature in the air drying cavity 110 is higher, the evaporation speed of the water on the surface of the food is higher, and the air drying time is shorter. Of course, it is understood that in the hot air drying mode, the defrosting cycle may be stopped after the temperature of the air in the hot air drying chamber 110 is increased to a set value through the defrosting cycle.
