The quick-freezing tunnel is also called the tunnel-type quick-freezing machine. The principle is the same as that of the quick-freezing library. The biggest difference is that the quick-freezing tunnel can realize continuous quick freezing work and improve production efficiency. The entry and exit of goods in the quick-frozen cold storage needs to be realized by manual means. The frozen food needs to be put into the cold storage, the refrigeration equipment is turned on, and the food is quickly cooled and frozen. When the food is frozen, the refrigeration equipment is shut down, and the manual equipment is also required. The goods are moved out and transferred to a low temperature freezer or other place.
The use of the quick-frozen tunnel can eliminate the manual handling process, and the goods are transported to the tunnel through the conveyor belt. After the goods pass through the tunnel, they are quickly frozen and then transported out for the next step.
Freezing food through the quick-frozen tunnel, as long as the source of the goods continues to enter the tunnel, there is constant heat generation, the refrigeration unit will continue to run until the cargo stops conveying, and the unit will automatically stop according to the temperature inside the tunnel. It not only improves the utilization rate and production efficiency of the equipment, but also saves the power consumed by the unit due to frequent startup, and plays a role in energy saving.
Quick Frozen Tunnel Category:
1 flat mesh belt type quick-freezing tunnel: suitable for meat, food, aquatic products, dishes, ice cream, etc. It is a basic general-purpose quick-freezing tunnel. Its output is from 100kg/h to 2000kg/h.
2 Multi-functional vibrating mesh belt quick-freezing tunnel: Add dynamic device on the basis of universal flat belt type single quick-freezing tunnel. In addition to the characteristics of the universal flat belt type single quick-freezing tunnel, it is also suitable for the freezing of granular food monomers.
3 tunnel type pre-cooling quick-freezing tunnel: creatively combines pre-cooling and quick freezing into one, saving energy. Especially suitable for high temperature storage, cooked food, fast food, etc.
4 tunnel type multi-layer mesh belt quick freezing tunnel: suitable for products with small footprint and long freezing time.
5 tunnel reciprocating quick-freezing tunnel: suitable for small footprint, long freezing time and process reprocessing products.
6 tunnel type belt quick freezing tunnel: suitable for quick freezing of aquatic products.
Various changes occur during food freezing, such as physical changes (volume, thermal conductivity, specific heat, dry consumption changes), chemical changes (protein denaturation, color change, etc.), cellular changes, and biological and microbial changes. . The frozen food is characterized by maximizing the original nutritional value and color and aroma of the food, i.e., the quick freezing freezer is designed to ensure maximum reversibility of the above changes in the food during the freezing process.
deal with. Frozen foods have the following advantages:
1. Avoid the formation of large ice crystals between cells; 2. Reduce the release of water in cells and reduce the loss of juice during thawing
3. The concentration of solute, food tissue, colloid and various components in the cell tissue is significantly shortened, and the degree of harm to the lowest level is reduced;
4. Rapidly reduce the temperature of food growth activities of microorganisms, which is conducive to the resistance of microbial growth and biochemical reactions; 5, food stays in the cold storage for a short period of time, which is conducive to improving the utilization rate of refrigeration equipment and continuous production efficiency. One kind
The fast freezing tunnel is also called a tunnel fast freezer. As with the principle of fast freezing storage, the biggest difference is that the quick freezing tunnel can achieve continuous rapid freezing work and improve production efficiency. The entry and exit of goods in the fast refrigerator needs to be done manually. Frozen foods need to be placed in the refrigerator. The refrigeration unit starts to run and quickly freezes the food. When the food is frozen, the refrigeration unit stops. At this point, the goods need to be manually moved to a cold storage or other location. The use of a quick-frozen tunnel saves the manual process, transports the goods to the tunnel through the conveyor belt, the cargo is quickly frozen through the tunnel, and then shipped out, the next step. By freezing the food through the fast freezing tunnel, as long as the cargo continuously enters the tunnel and generates heat, the refrigeration unit will run until the cargo stops, and the device will automatically stop according to the temperature inside the tunnel. It not only improves the utilization and production efficiency of the equipment, but also saves energy consumed by the equipment due to frequent startup, which plays a role in energy saving.
