Air blast Quick Freezing Process and Flash Freeze Machine

Air blasy Quick freezing (Individual Quick Freezer)  is rapid freeze of food by exposure to a blast of air at a very low temperature.
Unlike slow freezing, very small crystals of ice are formed which do not rupture the cells of the
food and so the structure is relatively undamaged.

A freeze tunnel is a process where the materials to be frozen are placed on an endless
conveyor and passed through the tunnel where the refrigerants are used to cool the air
and through circulation allow the material to become frozen.

In the freezer the product is individually quick-frozen. This means that a high capacity cold airflow
is blowing through the product. In the first stage brings the product on the temperature of -5°C. The second
is cooled down further till -18°C; a retention time in a freezer is minimum 9 minutes.

Tunnel quick freezer application

Tunnel quick freezer is are suitable for frozen fruits & vegetables, meat, seafood, such as asparagus, broccoli, carrot, strawberry, beef, divided meat ,shrimp, sliced fish, meat ball, etc.

As a frozen French fries machine, the tunnel instant freezer works after chips fryer, it could keep it fresh for long time storage. The frozen French fries keep the original taste and are crispy. Frozen fries are of the best quality as service of top restaurants’ French fries.

In the latest vacuum frying process, tunnel freezer is often used before vacuum fryer. Vacuum fried vegetable and fruit chips keep the natural taste and more crisp, more popular with low-fat content and retaining the desirable texture and flavor.

Tunnel Quick Freeze Machine Features

Tunnel Quick Freeze Machine adopts environment friendly and high efficient compressor and environmentally friendly refrigerant
R404 or R507.

Tunnel Quick Freezer is an efficient impingement mesh belt tunnel quick-freezing device

Due to blast air of higher velocity in freeze tunnel with the unique air ducting to achieve a uniform
air distribution, unfrozen food material like fries, chips and fresh vegetable is fully exposed in the strong cold air.

There are independent vibration devices under the belt mesh; the mesh space is not block with frost,
less wind resistance reducer, much stronger cold air flow smoothly. Also freezing materials will become
into individual frozen food without agglomerate and sticks.
