Features

1. The IQF Spiral Freezer utilizes a compact, multi-layer spiral structure, reducing its footprint by 1/3 to 1/2 compared to conventional freezers of the same capacity, making it ideal for facilities focused on space efficiency.

2. LSJ IQF Spiral Freezers incorporate years of practical experience and cutting-edge international technology, offering unparalleled reliability. Robust mechanical and electrical safety features ensure worry-free operation even in demanding industrial environments.

3. This freezer features customizable inlet and outlet directions, easily adapting to various food production layouts. Whether used with frying lines, packaging systems, or processing units, it streamlines workflows and increases productivity.

4. The Spiral IQF Freezer’s streamlined design requires virtually no training to operate. Key highlights include an aluminum alloy evaporator with easy-to-clean fins to reduce bacterial growth and a high-speed cleaning system for instant conveyor belt drying, ensuring stringent hygiene standards. Furthermore, its durable design reduces the number of replaceable parts, reducing maintenance costs.

5. This versatile unit is suitable for a wide range of frozen foods, processing everything from noodles, spring rolls, and meat products to fruits, vegetables, fried snacks, and packaged foods, making it a versatile solution for food processors.

6. Constructed of high-quality SUS304 stainless steel, the freezer ensures that products are placed directly onto the conveyor. The smooth conveyor surface virtually leaves no marks on items, while side chains with non-slip stops keep trays securely in place, minimizing product waste.

7. To optimize performance, symmetrical circular air ducts are designed around the spiral tower and evaporator. This innovative design not only accelerates heat exchange but also prevents cooling loss at the entry and exit points. Most importantly, it maintains operator-friendly operation and easy maintenance.
