Food cold storage is a building that uses artificial refrigeration to allow a fixed space to reach a specified temperature to facilitate the storage of food. Food cold storage is the most common type of cold storage construction. When installing, designing and constructing, it is very important to ensure a very good heat insulation performance of cold storage, otherwise it is easy to cause the deterioration of the stored food, or increase the operation load of the cold storage refrigeration system and reduce the service life.

When designing and constructing the installation of food cold storage, the cold storage engineer will select * appropriate thermal insulation materials and * effective thermal insulation material installation methods according to the heat transfer equation inside and outside the cold storage maintenance structure, the thermal inertia index equation, the thickness calculation and publicity of thermal insulation materials, etc. in combination with the actual use requirements of the food cold storage construction. In order to reduce the introduction of external heat, the floor, walls and roof of the cold storage are laid with a certain thickness of insulation layer to achieve very good heat insulation performance. Among them, polyurethane foam is regarded as a kind of ideal cold storage engineering heat insulation material in the world, because of its strong moisture resistance, pressure resistance and water vapor permeability. For the design and construction of food cold storage, this is a very cost-effective cold storage insulation material.
Food is closely related to human life products, food refrigeration and freezing is directly related to food nutrition, taste, color and other major factors. In the refrigeration process, the refrigeration system should be able to provide a constant cooling capacity, can maintain the appropriate temperature of food storage, and can not have a large temperature fluctuations, which is to ensure the storage process, the key to food quality. Rapid cooling and rapid freezing are very common links in the process of food processing, which is the key to determine the quality of food initial processing. For fast cooling food, attention should be paid to the influence of wind speed and rapid cooling on the appearance of food due to thermal expansion and contraction. During the rapid freezing process, the food should quickly pass through the large ice crystal generation zone to ensure that the organization of the food is not damaged by ice crystals, keep the taste and nutrients of the food as fresh as possible.
