SSD Series Tunnel IQF Freezer

Tunnel IQF freezers are designed specifically for freezing small, flat, granular products such as shrimp, fish fillets, and hamburger patties.

In addition, this IQF tunnel freezer features a unique airflow design. As products pass through the freezer on a conveyor belt, high-pressure air flows from both sides of the product.

Specifically, when freezing shrimp, the high-pressure airflow rapidly cools them to the desired freezing state. For fish fillets, the uniform airflow ensures rapid and even freezing, preventing uneven freezing. And when processing hamburger patties, the high-pressure airflow rapidly crystallizes the moisture within the patty, effectively locking in its nutrients and flavor.

In summary, this unique design significantly shortens the dwell time required for freezing, significantly reducing weight loss and increasing yield, bringing significant economic benefits to food processing companies.

Important Parts Display

Belt Conveyor System	Freezer Frame
Integral mesh belt design, mesh belt drives motor; two-stage cycloid pin gear motor, speed control of mesh belt with frequency conversion and stepless speed regulation. The mesh belt adopts wear resistant roller and bracket to reduce the wear and running resistance of the mesh belt, extending the service life of the mesh belt. Add abrasion – resistant rubber strip on both sides of the mesh belt, prevent leakage in the warehouse.	The frame is made of stainless steel, with square tubes; The stainless steel plates inside and outside the library are stainless steel plates. The transmission shaft and the chain wheel contact with the mesh belt are made of food-grade stainless steel and the nylon roller is made of ABS.
Air Supply System and Evaporator	Electric Cabinet
Adopt efficient axial-flow fan specially designed for tunnel cooling, with high wind pressure, large air volume, light air blade weight, small start-up current. Large aluminum alloy aluminum tube fin with efficient refrigeration. The structure of the evaporator is different, and the sheet spacing of each evaporator is designed with variable sheet spacing to ensure continuous and efficient freezing of the quick-freezing function and extend the frost interval. Adopting the closed air guide cover and the equalizing wind mechanism.	Vertical cabinet structure, the shell is made of stainless steel. Electrical components: the electrical components are Schneider or CHNT. PLC and touch screen are Siemens. Temperature display: multi-point display (inlet, outlet and center of library each has 1 set). The storeroom is equipped with a water-proof safety lamp lighting system, and the lighting is 36V safe voltage. The anti-freeze device system of the storage door, with 36V safe voltage.

Features

1. IQF tunnel freezers prevent the formation of large ice crystals, preserving cell integrity and overall product quality.

2. Shorter freezing times not only preserve product freshness and nutritional value, but also increase yields with lower energy consumption.

3. Operating costs are significantly lower than CO2 and liquid nitrogen freezing methods.

4. The shortened freezing time reduces the overall length of the freezing equipment, thereby reducing installation space requirements.
