Trinidad and Tobago Seafood cold storage

How should the price of cold storage be calculated? What are the factors that affect the price of cold storage? I believe that many customers are concerned about this issue. I will introduce to you what factors are mainly considered for the price of cold storage.

    1. The location of the cold storage-external ambient temperature

    The construction of cold storage is restricted by the temperature difference between the inside and outside of the cold storage and the difference in water vapor partial pressure. According to the nature of the cold storage, the long-term internal temperature of the cold storage is within the temperature range of -40℃~0℃. Periodic fluctuations, coupled with the need for frequent door openings in cold storage production operations, leading to the exchange of temperature, heat and humidity between the inside and outside of the cold storage, have prompted cold storage buildings to adopt corresponding technical measures for heat insulation and vapor insulation to adapt to the characteristics of cold storage. This is also the difference between cold storage construction and The characteristics of ordinary buildings.

    2. The size of the cold storage

    The size and number of refrigerators are related to the size of the cold storage.

    3. What is the cold storage used to store?

    The temperature required for storage of different items is different, general vegetables are kept fresh at 0°C, and meat is refrigerated at -18°C.

    4. The temperature that the cold storage is required to reach

    Cold storage can be divided into four categories: high temperature, medium temperature, low temperature and ultra-low temperature. usually:

    The temperature of the high-temperature cold storage is -10℃~+8℃, which is suitable for the preservation of fruits and vegetables; the medium-temperature refrigeration temperature is -10℃~-23℃, which is suitable for the refrigeration of frozen food; the temperature of the low-temperature cold storage is generally -23℃~-30 ℃, suitable for the refrigeration of frozen aquatic products and poultry food; the ultra-low temperature quick-freezing freezer temperature is -30℃~-80℃, suitable for rapid freezing treatment before fresh products are refrigerated.

    Advantages of food cold storage:

    1. The activities of substances and enzymes are also inhibited, the overall metabolism is slowed down, and the preservation period of fruit and vegetable foods is prolonged. When the temperature is raised from the cold storage and then sold at room temperature, the original flavor and freshness are restored, and the economic benefits are effectively guaranteed.

    2. Food cold storage construction. Meat food is processed by cold storage. If it drops to about 0℃, the meat itself will not freeze. At the same time, the growth and reproduction of spoilage microorganisms will slow down. The freshness period and quality are also well guaranteed. We often say "chilled fresh"; if it drops to a lower temperature, such as -18°C and below, the meat's own moisture and juice will change from water to ice in a short period of time, and it will not be able to supply the water necessary for microbial life. At the same time, low temperature also hinders the growth and reproduction of microorganisms, which can greatly improve the storage resistance of meat products and achieve farther and longer sales.

    3. Food cold storage construction During the process of food refrigeration, the food itself contains nutrients such as sugars, proteins, fats, and inorganic salts, which will hardly be lost, so that the flavor of the food remains the same when it is eaten at room temperature.
