Impingement Tunnel Freezer

Square‘s tunnel freezer is suitable for quickly freezing granular, diced, flat food and other foods that require a good appearance after freezing such as shrimp, fish fillets, meat burgers, etc.

Our tunnel freezer utilizes high-velocity air jets that direct their force at the top and bottom of a food product to remove the air, or thermal barrier, surrounding the product surface.

This allows for faster freezing of the product and reduces processing times considerably, giving freezing times similar to those provided by cryogenic equipment. In addition, operating costs are similar to those of traditional mechanical equipment.

Faster freezing, juicier foods, less drip loss
Energy saving and small footprint
