OSJ Tunnel Freezer®. – TAKAHASHI GALILEI CO.LTD.

Tunnel Freezer® is specially designed for freezing products in bulk by floating them. It is ideal for products such as rice and corn that are to be frozen in granular form.

Multi-flow Freeze System
Unlike conventional freezing methods, this system blows cold air from below the conveyor and freezes products in pieces while they float (IQF). The conveyor is a two-stage system, with the first stage freezing the surface and the second stage completely freezing the core.

Belt conveyor system
Two types of belts can be selected.

Plastic Belt:.
Suitable for frozen vegetables such as spinach and corn. The perforated belt blows cold air up from under the holes.

Mesh belt.
This type of belt is often used for rice, seafood, and meat, and uses a fine mesh belt that does not allow even a single grain of rice to penetrate.

Panel type exterior wall structure
This is a structure consisting of heat-insulating panels in which urethane foam is sandwiched between steel plates. These heat-insulating panels are designed to the high precision required for Tunnel Freezer®, and are produced by Galilei Panel Create, a group company.

Super-jet system is used for steel belt conveyor. Products are finished flat without net marks. This model is supported by many customers in the fisheries industry.

Super Jet Rapid Freezing
Our original SJ nozzle has an independent structure to achieve a smooth flow of cold air with no back pressure and a high-speed jet stream. It destroys the temperature boundary layer on the product surface and rapidly removes heat from the top and bottom of the product.

Improved cleaning performance
The use of an all-air blast system instead of the conventional brine system eliminates the need for brine management. This simplifies the structure of the chamber and contributes to shorter cleaning time.

Steel belt
The underside of the product is frozen by direct contact with the stainless steel belt, while the upper side is quickly frozen by a jet stream from the SJ nozzle. Since no net remains on the product, it is suitable for freezing unwrapped marine products, fresh meat, liquid in bags, etc.
