What is a double spiral freezer?

The double-spiral quick freezer is an efficient piece of equipment designed for the rapid freezing of large quantities of food, specifically engineered to handle small to medium-sized granular, strip, or block foods such as steamed buns, dumplings, seafood, vegetables, and various processed food items. The core feature of this freezer lies in its unique double-spiral structure, which utilizes two parallel spiral conveyor belts to guide the food from the feeding end through the freezing zone to the discharge end. During the freezing process, the food is not only continuously lifted or lowered by the spiral structure but is also rapidly cooled by the surrounding high-speed airflow, ensuring that the food passes through the ice crystal formation zone in a short time. This minimizes nutrient loss and preserves the original flavor and texture of the food.

Features of double spiral quick freezer

Equipped with a double-drum structure, it maximizes the characteristics of the spiral quick freezer, significantly improving freezing efficiency. The drums and conveyor belts are supported by polyethylene protective strips, which are both wear-resistant and durable, extending the service life of the stainless steel mesh belt. Its optimized airflow design ensures insulation and prevents the evaporator from frosting, thereby extending defrosting intervals. With high elongation resistance and wear resistance, it enhances the lifespan and stability of the double-spiral quick freezer. Equipped with a conveyor belt monitoring device, it continuously checks the operating condition of the conveyor belt to prevent unnecessary losses caused by conveyor belt failures.
