Spiral Freezer from OnlyKem Brand

Spiral freezer is also called air blast freezer, IQF or tunnel freezer which is mainly used to freeze a large number of content at short time. It can maintain the high quality of products, keep product’s texture, moisture and flavor throughout the entire freezing process. There are typically 3 main blast freezer models: batch style freezer, tunnel freezer and spiral freezer models which are most used in the food industry.

Tunnel freezers have been used in large scale production lines for decades. The base design of the air based tunnel freezer has stayed, for the most part, un-changed. With the main concept of it still being inputting the product in one side and extracting the frozen product at the end. This process enables enterprises to freeze continuously for a long time. Compared with conventional batch freezing, the whole process uses less labor.
