Pre-cooling is a cooling method that is performed before long-distance transportation or refrigerating of food , and the requirement is to rapidly reduce the food to be stored to a prescribed temperature. It is an important measure to maintain the quality of the food being transported and to extend its shelf life. Pre-cooling is usually carried out between cold storage and pre-cooling. Common pre-cooling methods include natural air cooling, ventilation cooling, vacuum cooling, and cold water cooling. The pre-cooled food should be quickly stored in a low-temperature environment.
2 temperature range and shelf lifeThe temperature in the refrigerator may not be constant at a certain temperature value. Because the performance of the refrigerator, the size of the storage capacity, and the temperature difference between inside and outside, the temperature of the storage tank may fluctuate within a certain range. In general, foods are stored at a lower temperature, and the smaller the variation, the better. This is conducive to food preservation, prevent loss and low temperature physiological diseases.
3, temperature controlDifferent foods have different optimum refrigeration temperatures. The cold storage temperature and the temperature of the food after storage are affected by various factors, such as the difference between the temperature of the food and the storage temperature at the time of storage, the efficiency and capacity of the refrigerator , the air circulation inside the warehouse, the stacking method, the food variety and maturity. Degree and so on. When storage, stacking should be reasonable, and the storage temperature should be adjusted according to the actual situation. Before the storage, a gradual temperature increase method should be adopted to avoid condensation on the food surface due to large temperature difference between inside and outside.
4, the control of humidityCold storage is often caused by the large amount of heat absorbed by the evaporator, and frost is continuously attached to it, and the ice is continuously melted away. As a result, the humidity in the storage tank is often lower than the humidity required for food storage. The humidity in the cold room can be adjusted by increasing the evaporator area, reducing frost formation, installing a spray device or an automatic humidifier. In addition, when the relative humidity of the warehouse is increased due to the frequent in and out of the goods, the moisture absorption device can be installed to absorb moisture, and the cold storage management can be strengthened , and the frequent entry and exit of goods and personnel can be strictly controlled.
