Cold storage plays an important role in food processing, preservation, and transportation. However, different types of cold storage have different features and functions. Among them, quick-frozen cold storage and ordinary cold storage are two common types, and there are some obvious differences between them. This article will introduce the difference between quick-frozen cold storage and ordinary cold storage in detail.
1. Function and Purpose.
1. Quick-frozen cold storage: Quick-frozen cold storage is mainly used for rapid freezing of food to maintain the freshness and taste of food. The temperature of the blast freezer is usually set between -20 30 to ensure that the food is frozen quickly in a short time.
2. Ordinary cold storage: Ordinary cold storage is mainly used for low-temperature storage and preservation of food. The temperature of ordinary cold storage is usually set between 0 5 to maintain the quality and taste of the food.
2. Design and structure.
1. Quick-frozen cold storage: Quick-frozen cold storage usually uses large-capacity, high-efficiency refrigeration equipment to ensure that food is frozen quickly in a short time. At the same time, the insulation layer of quick-freezing cold storage is usually thicker to reduce the loss of cold capacity.
2. Ordinary cold storage: The design of ordinary cold storage is relatively simple, usually using smaller refrigeration equipment and thinner insulation layer. The structure of ordinary cold storage is also relatively simple to meet the needs of low-temperature storage and preservation.
3. Operation and maintenance.
1. Quick-frozen cold storage: The operation and maintenance of quick-frozen cold storage are relatively complex, and professional and technical personnel are required to operate and maintain it. At the same time, due to the low temperature of the quick-freezing cold storage, it is necessary to regularly check the operation status of the refrigeration equipment and the integrity of the insulation layer.
2. Ordinary cold storage: The operation and maintenance of ordinary cold storage is relatively simple, and generally only need to regularly check the operation status and temperature control of refrigeration equipment.
4. Scope of application.
1. Quick-frozen cold storage: Quick-frozen cold storage is suitable for food processing enterprises and meat processing enterprises that need to be frozen quickly. These businesses need a large number of refrigeration equipment to meet production demand.
2. Ordinary cold storage: Ordinary cold storage is suitable for food processing enterprises, supermarkets, restaurants, etc. that need low-temperature storage and preservation. These businesses need a lot of refrigeration equipment to meet their storage and preservation needs.
In short, there are obvious differences between quick-frozen cold storage and ordinary cold storage in terms of function, design and operation. Choosing the type of cold storage that suits your needs is of great significance to ensure food quality and improve production efficiency. Cold storage installation
