The IQF Cryogenic Freezer process utilizes the "wind chill" effect to increase the freeze rate for products. The high velocity gas flow created by the circulating fans, continually removes the thin insulating envelope of static gas that normally surrounds the product to be frozen. This allows the cold Nitrogen or CO2 gases to be in very close contact with the surface of food products. The rapid freeze achieved by the high velocity gas flow reduces product shrinkage and moisture loss, as well as maintains final quality of the product.
Insulated Shipping Containers (or Dry Ice Boxes) are Designed for the Dry Ice, Frozen Food, Medical, Chemical, Pharmaceutical Industries, or Any Industry Where Cold Temperatures Must be Maintained for Extended Periods of Time.
The main advantage of Mechanical Freezing over Cryogic Freezing is generally lower operating costs. However, the Cryogenic Freezer has much lower capitol equipment costs and lower maintenance costs.
Cryogenic Freezers meet all FDA requirements while Mechanical Freezers have to fill out risk management plans because Ammonia is highly toxic.
Cryogenic Freezers can reach temperatures of -180F to freeze food quickly. Mechanical Freezers can reach max low temperatures of -30F.
The main concern with a Fiberglass outer shell is it's not as durable as a Stainless Tunnel, but the Fiberglass outer shell is strong, sleek, & extremely durable.
Fiberglass acts as a better insulater against the outside environment compared to Stainless freezers.
Fiberglass Tunnels have lower cost of capital equipment compared to Stainless Tunnels. Also, maintenance work is much less expensive and easier with a Fiberglass Freezer.
Everyday cleaning is much easier with the Fiberglass Freezer. No dead corners where bacteria can grow.
