The composition of display cooler (1)
The composition of display cooler display cooler, especially the large and medium-sized display cooler is a building group, mainly composed of the main building (main cabinet), other production facilities and auxiliary buildings. is summarized as follows: 1. The main cabinet is mainly composed of the following units. (1) Cooling room: The cooling room is a cabinet room used to cool and process food. Before fruits and vegetables are refrigerated, in order to remove field heat and prevent some physiological diseases, they should be gradually cooled down in time. Fresh eggs should also be cooled before refrigeration. In order to avoid sudden cold, the content shrinks, the pressure in the egg decreases, and the microorganisms in the air enter the egg from the stomata of the egg shell with the air and make the fresh egg go bad. In addition, the livestock can also be processed into chilled meat after slaughter (the core temperature is 0~4℃), which can be stored for a short time, and the meat taste is more delicious than frozen meat. For the secondary freezing process, the carcasses of the slaughtered livestock also need to be sent to the cooling room for cooling, so that the food temperature is reduced from 35°C to 4°C, and then frozen. The room temperature of the cooling room is -2~0℃. When the food reaches the required cooling temperature, it is called cooler , which can be transferred to the cooler cold room. When the one-time purchase of fruits, vegetables and fresh eggs is less than 5% of the capacity of the refrigerated room, they can also enter the refrigerated room directly without cooling. (2) Freezing room: For food that needs to be stored for a long time, it needs to be quickly reduced from normal temperature or cooling state to a frozen state of -15~-18°C. The food that reaches the final freezing temperature is called frozen product . The freezing room is a cold room for freezing food with the help of air coolers or special freezing devices. Its room temperature is -23~-30℃ (foreign countries have adopted -40℃ or lower temperature). The freezing room can also be moved out of the main cabinet and built separately.
(3) Refreeze room: It is set in the distributive display cooler, and is used for refrigerating the part of frozen food that has a temperature over -8℃ before entering the cabinet. The selection of cold distribution equipment in the refreezing room is the same as the freezing room. (4) Cold storage room: This type of cold storage room is also called high-temperature storage room. The room temperature is -2~4℃, the relative humidity is 85%~95%, which varies with the food storage. It is mainly used to store fresh eggs, fruits and vegetables after cooling: Since fruits and vegetables still have a respiration effect during storage, in addition to maintaining suitable temperature and humidity conditions, appropriate amounts of fresh air must be introduced in the cabinet. If storing chilled meat, the storage time should not exceed 15 days. The above articles are from refrigerated showcase display cooler and display cooler.
