Cold
Refrigerated storage means the creation, by manual means, of an environment different from the outdoor temperature or humidity and is also a constant-moisture storage facility for food, liquids, chemicals, medicines, vaccines, scientific experiments, etc. Refrigerated banks are usually located near the port of transport or place of origin. Refrigeration banks can be divided into various types according to different criteria, with the structure of both indigenous and assembly cold banks; production colds, distribution colds and retail colds by use; high temperature colds, medium temperature colds, low temperature colds and ultra-low temperature colds by temperature. So, what are the characteristics of the freezers by temperature
Food
I. High temperature freezers
Temperature range: typically between 0°c and 15°c。
Characteristics:
- they are used mainly to store items that do not require high temperature, such as vegetables, fruits, flowers, dairy products, baked foods, etc。
- maintenance of the freshness and quality of items and extension of storage periods。
- higher relative humidity, which helps to maintain the humidity and taste of the articles。
Sport
Ii. Medium temperature freezers
Temperature range: typically between 5°c and 0°c。
Characteristics:
- for the storage of foods such as meat, fish, poultry, etc. That require cold storage。
- controlling the growth of microorganisms by controlling temperature and extending the shelf life of food products。
- the relatively stable storage environment is conducive to maintaining the taste and nutritional value of food。
Sport
Iii. Cryogenic freezers (frozen freezers)
Temperature range: there are also coolers for lower temperatures generally between 18°c and 25°c。
Characteristics:
- for the storage of foodstuffs requiring long-term cold storage, such as fast-frozen foods, meat, seafood, etc。
- inhibiting the growth and reproduction of microorganisms through extremely low temperatures to ensure the safety and quality of food。
- a stable storage environment conducive to the long-term conservation of foodstuffs。
Sport
Iv. Ultra-low temperature freezers
Temperature range: typically below -40°c, some can reach -80°c or even lower。
Characteristics:
- industries or materials that apply to the storage of special requirements, such as deep sea fish, medical preparations, medical cells, biological products, etc。
- super-temperature environments are more effective in inhibiting the growth and chemical reactions of microorganisms, ensuring stable active ingredients in samples and medicines and extending storage periods。
- higher requirements and relatively higher costs for equipment and technology。
Each type of freezer has its specific application scene and advantages, and the selection of the appropriate type of freezer is essential to ensure the safety, quality and length of storage of food. At the same time, different types of freezers need to be designed and operated taking into account different factors, such as temperature control, moisture regulation, ventilation, etc. To ensure the stability and reliability of the storage environment. For many years, it has been dedicated to cooling industrial plants, ventilating factory workshops, defusing air, cooling, etc., as well as to the development and operation of the overall programme of ventilating equipment at various other sites. It has introduced the plant's cooling and ventilation system, the air-replacement system, environmentally friendly air conditioning, industrial fans, water curtains, anti-winders, cold storage, etc., and has won many clients ' favors with their excellent practical and energy-saving effects. Advice is welcome if you have any questions and needs relating to cooling in high space, cooling in plant workshops, dust removal and cooling。
