The 8-sided form minimises the space around the belt, thus achieving the highest possible cold gas speed. The nitrogen supply and gas balance are controlled by a state-of-the-art automatic system.

The very low operating temperatures, achieved by using liquid nitrogen ensure very fast freezing that preserves the quality and the shape of the product and keeps the weight loss to a minimum. Cryogenic freezing is normally most economical at low to medium volumes, but with this CRYOLINE spiral, it is also suitable for high volumes or when high quality is needed. Additionally, this system offers a high level of hygiene and safety combined with low consumption and easy operation.

The spiral acts as a heat exchanger, in which the liquid nitrogen is sprayed directly on the product, thus efficiently extracting heat from it. The generated cold gas is circulated around the products and then extracted by the exhaust system. The exhaust system in the CRYOLINE CS is adjustable, which means that the gas can be fully utilised before leaving the spiral, which guarantees a very low gas consumption and low running costs. In the spiral design, the working environment has been given the utmost importance. This has been secured by choosing a low noise fan and by carefully insulating all points through which a contact to the very cold nitrogen could occur. The spiral is easy to operate by means of automatic control devices. It is cooled down and ready for operation in less than twenty minutes.
