What are the differences between a quick-freezing cold storage and a quick-freezing tunnel? Many people may not particularly understand. "Quick freezing", also known as "quick freezing", refers to the rapid freezing of food through its largest ice crystal formation zone, and the core temperature reaches -18°C. "Quick freezing" generally includes three process methods: quick freezing cold storage, quick freezing tunnel, and quick freezing flat plate. Today, I will analyze the difference between a quick-freezing tunnel and a quick-freezing warehouse.
1. Quick-freezing cold storage
Quick-freezing cold storage, also known as quick-freezing storage. Quick-freezing cold storage usually requires relatively large-scale refrigeration equipment. The cooling capacity of the equipment is directly proportional to the amount of quick-freezing of the food and inversely proportional to the time of the quick-freezing. The quick-freezing storage quickly passes the food through its maximum ice crystal formation area, and the center temperature reaches -18℃. freeze. Food will undergo various changes during freezing, such as physical changes (volume, thermal conductivity, specific heat, dry consumption, etc.), chemical changes (protein denaturation, color change, etc.), cell tissue changes, and biological and microbial changes Wait. The characteristic of quick-freezing food is to keep the original nutritional value, color and fragrance of the food to the maximum extent, that is to say, the quick-freezing cold storage guarantees the maximum reversibility of the above-mentioned changes in the food during the freezing process. The quick-frozen food has the following advantages:
1. Avoid the formation of large ice crystals between cells;
2. Reduce the leakage of moisture inside the cell, and less juice loss when thawing;
3. The contact time of concentrated solutes, food tissues, colloids and various components in cell tissues is significantly shortened, and the harm of concentration is reduced to a minimum;
4. Quickly reduce the food to below the temperature of microbial growth activity, which favorably resists the growth of microbes and their biochemical reactions;
5. The food stays in the cold storage for a short time, which is beneficial to improve the utilization rate and continuous production efficiency of refrigeration equipment.
2. Quick-freezing tunnel
The principle of quick-freezing tunnels is the same as that of quick-freezing warehouses. The biggest difference is that quick-freezing tunnels can achieve continuous quick-freezing work and improve production efficiency.
1. Flat mesh belt quick-freezing tunnel: suitable for meat, prepared food, aquatic products, dishes, ice cream, etc. It is a basic general-purpose quick-freezing tunnel. Its output is 100kg/h-2000kg/h.
2. Multifunctional vibrating mesh belt quick-freezing tunnel: a dynamic device is added to the general-purpose flat mesh belt quick-freezing tunnel. In addition to the characteristics of a general-purpose flat mesh belt type monomer quick-freezing tunnel, it is also suitable for the freezing of granular food monomers.
3. Tunnel-type pre-cooling and quick-freezing tunnel: creatively combines pre-cooling and quick-freezing into one to save energy. It is especially suitable for high-temperature incoming goods, cooked food and quick-cooling food, etc.
4. Tunnel type multi-layer mesh belt quick-freezing tunnel: suitable for products with small area and long freezing time.
5. Tunnel reciprocating quick-freezing tunnel: suitable for small area, long freezing time and process reprocessing products.
6. Tunnel-type slab-strip quick-freezing tunnel: suitable for quick freezing of aquatic products. The quick-freezing tunnel transports the goods into the tunnel through the conveyor belt. The goods are quickly frozen after passing through the tunnel, and then transported out for the next step. The food is frozen through the quick-freezing tunnel. As long as the goods continuously enter the tunnel and there is continuous heat generation, the refrigeration unit will continue to operate until the goods stop transporting, and the unit will automatically shut down according to the temperature in the tunnel. It not only improves the utilization rate and production efficiency of the equipment, but also saves the electric energy consumed by the frequent start-up of the unit, which plays a role of energy saving.
The difference between quick-freezing tunnel and quick-freezing cold storage is introduced here. Xiaodao Refrigeration, as a well-known brand in the cold storage industry, has been focusing on the field of refrigeration. Relying on the professional level and mature technology in the refrigeration field, it has risen rapidly in the industry. Hope to work together with all parties in the industry to contribute to the development of the cold storage industry.
What is the difference between a quick-freezing cold storage and a quick-freezing tunnel, do you know?
