Tunnel Freezer

The tunnel freezer is a direct contact freezer which is developed basing on air blast freezing method, and relies on the forced, high speed, cold air circulation to remove heat from the products to be frozen. Freezing with the use of air as the cooling medium, through a heat convection process to transfer heat, and finally achieves a fast freezing performance.

With over 20 years' experience of designing and manufacturing tunnel freezer, we have developed several types of tunnel freezer for various products freezing.

Tunnel Freezer we've produced
    1. Solid Band Tunnel Freezer
    2. Solid Band Tunnel Freezer The tunnel freezer is primarily used to freeze flat food products, such as fish fillets, peeled shrimps, squids, dumplings, etc. The tunnel freezer is equipped with a hygienic and highly effective evaporator, which uses the newest liquid supply method, allowing for higher heat exchange efficiency than traditional method by 20%.
    1. Mesh Belt Tunnel Freezer
    2. Mesh Belt Tunnel Freezer The mesh belt tunnel freezer is used to achieve a quick freeze process for granular and small pieces of food. A larger mesh belt tunnel freezer is also applicable to individual quick freezing of prepared food, such as an entire chicken or fish. This freezer is also capable of being connected to the front or back of other customer processing lines.
    1. Impingement Band Tunnel Freezer
    2. Impingement Band Tunnel Freezer The tunnel freezer is primarily used to freeze food products, such as fish fillets, peeled shrimps, squids, dumplings, etc. Due to its air blasting mode, the tunnel freezer features high freezing efficiency and a variety of applications in food processing.
    1. Impingement Belt Tunnel Freezer
    2. Impingement Belt Tunnel Freezer The impingement belt tunnel freezer is primarily used to freeze flat foods, making it a popular choice in the seafood industry to quickly freeze fish fillets, shelled shrimps, squids and more. It is equipped with a highly efficient and hygienic evaporator and uses the latest liquid supply method for a heat exchange efficiency that is 20% higher than the traditional methods.
