Impingement Tunnel Freezer

Wolfking impingement tunnel freezer uses high velocity jets of air to directly blow at the top and bottom surfaces of product, and quickly reduce the outer temperature. Impingement cold air-jets remove the static surface boundary layer that surrounds the product resulting in a very fast freezing, small ice crystals and thus high product quality, minimizing dehydration loss.
It applies to products with a high surface area-to-weight ratio and ideally freeze shrimp, fish and other flat products, minimizes cellular damage, improves yield and increases shelf life to enhance food quality.
