Overview
The spiral quick-freezer is a continuous rapid-freezing system designed for industrial production of ice cream and portioned frozen foods. It combines a compact footprint with high throughput and adjustable freezing times to suit varied product types.

How it works
The unit uses conduction, convection and forced cold-gas heat transfer. Product is loaded onto a mesh belt spiral conveyor driven by a rotating drum. As the belt advances in a spiral path, items remain exposed to high-speed freezing air (liquid nitrogen, liquid CO2 or chilled air), rapidly extracting surface heat to achieve deep freezing within a short residence time. Continuous tumbling and belt contact ensure uniform freezing from infeed to discharge.

Main components

• Drive system
• Evaporator
• Enclosure panels

• Single-spiral: 500–1500 kg/h

Applications

• Ice cream cones
• Ice cream cups
• Ice cream sandwiches
• Mochi ice cream
• Ice cream bars and chocolate-coated ice cream
• Gelato products
• Frozen yogurt
• Ice cream cakes and frozen cheesecakes
• Specialty frozen snacks and portioned desserts
• Prepared foods, bakery goods, portioned meats, poultry, seafood, deep-fried items and small-packaged foods

Notes on operation & benefits
The spiral conveyor provides continuous tumbling and uniform exposure to high-speed freezing air, enabling fast surface hardening to limit ice crystal growth and preserve texture. The compact spiral arrangement delivers high freezing capacity within a reduced floor area and can be configured in single- or double-spiral layouts to match plant throughput and layout requirements.
