Learn MoreIQF Spiral Freezer
The spiral freezer is a high-efficiency continuous freezing machine widely used in meat, seafood, dough products, prepared foods, bakery products, and pet food industries. Through a spiral conveying system, it achieves a long freezing path within a compact footprint, allowing products to rapidly pass through the maximum ice crystal formation zone and preserve original quality and structure.
Overview
The spiral freezer adopts a continuous spiral conveyor belt structure, enabling high-capacity freezing within limited plant space. With features such as fast freezing speed, compact footprint, and high automation, it is ideal for medium to large food processing plants seeking standardized and large-scale freezing production.
Working principle
Products enter the spiral conveying system via the infeed conveyor and travel upward or downward along the spiral path under forced low-temperature airflow. Driven by fans, cold air circulates evenly and exchanges heat efficiently with the products, completing rapid freezing within the preset time.
Spiral Freezing Process
Products are pre-processed and evenly fed onto the infeed conveyor
Products enter the spiral conveying system
Rapid freezing occurs under low-temperature airflow
Products are automatically discharged after the preset freezing time
Products proceed to packaging or further processing
