Tunnel freezers are an important component in the industrial freezing process and are commonly used in industries such as food, pharmaceutical, and chemical. The purpose of a tunnel freezer is to quickly and efficiently freeze products, such as food, to preserve their quality and extend their shelf-life. In this blog, we’ll discuss how tunnel freezers work.

A tunnel freezer is a continuous processing system in which products are conveyed through a refrigerated tunnel. The tunnel is designed with a refrigeration system that circulates refrigerated air around the product. This cool air rapidly reduces the temperature of the product, causing the moisture inside to freeze.

The product is usually loaded onto a conveyor that runs through the tunnel. The speed of the conveyor and the duration of time the product spends in the tunnel are two important factors that determine the quality of the freeze. To ensure that the …
