Tunnel Type Quick Freezer For Fruits, Vegetables And Fish Products
Frozen food has become an important part of our daily diet due to its convenience and ease of preparation. However, the freezing process can also impact the quality and safety of the food. To address this concern, a quick freezing technique known as the tunnel freezer has been developed. The tunnel freezer is a continuous freezing system that can be used in a variety of food processing industries, including bakery, meat, seafood, and frozen vegetables.
A tunnel freezer is a type of freezer that operates on a continuous basis, allowing for a flow of products to be frozen at a high rate. The products travel through the tunnel on a conveyor belt, and as they move through the freezer, they are exposed to a blast of cold air. This cold air freezes the product rapidly, allowing for a quick and consistent freeze.
Speed of Tunnel Freezing
The speed of tunnel freezing is dependent on various factors,
including the temperature of the product going into the freezer,
the type of product being frozen, and the desired final temperature
of the product. Generally, the tunnel freezer can freeze food at a
rate of approximately 1,000 kg per hour, with a freezing time of 60
minutes or less. The center temperature of the product can reach
-18℃ or lower after the freezing process.
Benefits of Tunnel Freezing
There are several benefits to using a tunnel freezer for food
processing:
1. Consistent Freezing: The tunnel freezer allows for a consistent and uniform freezing of products. Each product will receive the same amount of cold air exposure as it passes through the freezer, resulting in a uniform freeze.
2. Continuous Production: The tunnel freezer allows for continuous production, allowing food processing facilities to increase their production output while decreasing costs.
3. Quality Preservation: The tunnel freezer preserves the quality of the product by freezing it rapidly, which prevents the formation of large ice crystals that can damage the structure and texture of the food.
4. HACCP Compliant: The tunnel freezer is designed and manufactured according to the Hazard Analysis and Critical Control Point (HACCP) principles, ensuring food safety and hygiene.
Conclusion
The tunnel freezer is a fast, efficient, and consistent way to freeze food products on a continuous basis. It allows for a high throughput of products while maintaining the quality and safety of the food. With the ability to reach temperatures as low as -18℃ in 60 minutes or less, the tunnel freezer is an important tool for the food processing industry.
| Structural features | |
| 1 | Simple structure, convenient operation and long service life. |
| 2 | The conveying mesh belt is made of high-strength SUS304 stainless steel mesh, which is safer to use, and the frozen products will not leave traces directly on the surface of the mesh belt. Mesh belt width can be selected upon request. |
| 3 | According to the production requirements, the combination of single and double mesh belts can be selected. |
| 4 | The thermal insulation storage body is made of double-sided SUS304 stainless steel polyurethane storage board, with inspection doors, double-layer sealing devices and heating devices to prevent freezing. |
| 5 | The air guide device in the warehouse adopts high-efficiency and low-noise axial flow fan and thermal fluctuation technology,and the freezing efficiencyis increased by about 15%-30%. |
| 6 | Use water to wash the cream to ensure cleanliness. The evaporator is made of aluminum alloy material, aluminum tube and aluminum fins, which is easy to clean. The design of variable blade distance can effectively prevent frost blocking and prolong the time of frost flushing. The unique liquid supply method makes the heat exchange more sufficient and the effect more obvious. |
| 7 | The imported frequency converter realizes inorganic speed regulation, and the freezing time can be adjusted continuously according to the needs, which can adapt to various freezing processes. |
| 8 | Stainless steel electric control box, stable quality, safe and reliable, easy to operate. The control system is equipped with a special alarmdevice and an emergency button to ensure the safe operation of the equipment. |
