IQF Tunnel/Spiral Quick-Freezers for Food Processing
The iqf freezer features a linear, constant-temperature design that meets the demands of high-tonnage, continuous batch production while allowing for capacity expansion through the parallel connection of multiple units, making it ideal for large-scale food processing operations. Products processed by this machine maintain excellent structural integrity and moisture retention, preserving the original flavor and nutritional value of the ingredients.

Other equipment
We specialize in two core types of equipment: tunnel-type and spiral-type quick-freezers. Based on specific operational requirements—such as hourly or daily processing capacity, available floor space, and product characteristics—we provide tailored equipment recommendations. Our solutions balance production efficiency, freezing quality, and space utilization, enabling enterprises to achieve highly efficient, energy-saving, and stable standardized quick-freezing operations that align with their production scale and processing workflows.
Tunnel Quick-Freezer
It specializes in the rapid freezing of large, whole, or stacked food items—specifically those that are resistant to sticking and can withstand the pressure of the conveyor system. Applications range from large cuts of meat, boxed ready-to-eat meals, and chunky fruits/vegetables to thick-cut ingredients, large seafood , large prepared meat products, and batches of baked goods. It is widely used in large-scale slaughtering facilities, fresh food processing plants, and industrial-scale ready-to-eat meal factories.
Spiral Quick-Freezer
The spiral quick-freezer utilizes a vertical spiral conveying structure to provide an extended freezing path within a minimal footprint. It achieves rapid, individual quick freezing (IQF) for each item, effectively preventing issues such as stacking, sticking, deformation, or breakage. It excels at individually freezing small, loose, sticky, fragile, or delicate food items. From seafood (shrimp, squid rings, fish balls, scallops), frozen pastries, and meat products (skewers, meatballs, seasoned diced meat) to fruits and vegetables (diced, sliced, or leafy greens).
Product Showcase
The tunnel freezer focuses on large-scale, high-capacity freezing for large-sized food materials. The spiral freezer specializes in space-saving, anti-sticking quick freezing for refined small-sized food. The two models cover full-category food freezing demands, adapt to different factory conditions and production scales, and solve industrial food quick freezing and efficiency improvement problems in one stop.
