Square Technology Group is a leader in food quick freezing solutions, ranging from the spiral freezer, tunnel freezer, impingement freezer, fluidized bed IQF, et cetera.

The self-stacking spiral freezer features a self-stacking belt, chain-driven system and vertical air flow. The food can be frozen in a shorter time and better quality. The self-stacking spiral freezer meets the highest hygiene and energy-efficiency standards.

The self-stacking belt is driven by a chain system and operates completely on rolling balls. The resistance and noise caused by running the chain are reduced, so smaller motors can drive the system. The belt is not in tension in the run. The belt is less likely to be stretched and deformed. Self-stacking belt stacks on the top of each other’s side links. This self-stacking feature eliminates the rails supporting the belt.

O design exclusivo da correia contém o produto numa zona de congelação autónoma, para um manuseamento suave e uniforme e uma higiene superior.

The vertical airflow of high velocity touches the product through all stacks, providing an even, quick, efficient freezing result. The special holes on the side links also introduce cold air into the product zone and create turbulence. This provides uniform product temperature across the belt and increases the heat-exchanging efficiency.

The Model STF 664008 self-stacking spiral freezers feature a 660mm wide self-stacking belt. The spiral freezer can freeze 1.5 tons/hour of different types of fried products, from 75℃ to -10℃ in less than one hour, while the traditional blast chamber takes at least 5 to 6 hours to freeze. It has increased the Russian customer’s output capacities and improved the quality of the frozen products. The spiral freezer is perfectly integrated into customer’s facilities. The production cost is reduced through less usage of labor, electricity, and water and better fluidity of the process.

The Russian hot stuff processing project is not Square Technology’s only successful project for fried products. We have already delivered other spiral freezers and IQF installations to other areas of the world, including the USA, Europe, New Zealand, etc.
