What is a Tunnel frieza?

It is a machine that enables freezing work while the worker is in a room temperature environment. Cold air is blown directly onto the food for quick freezing, and the machine is in the shape of a tunnel for the food to pass through. The inside of the freezer has a structure that can be sterilized by steam, and can be installed in a clean room. Food safety is maintained by quick freezing the temperature range (10 to 60 ° C) where bacteria are likely to grow when the overheated food is cooled. Compared to the batch-type freezer, which workers put in and out of the freezer with trays, the structure is less likely to cause unevenness when exposed to cold air. The type with a spiral conveyor called a spiral freezer is inferior in cooling performance to a tunnel freezer, but it can save space.

Application of Tunnel frieza

It is widely used in the fishery industry, frozen foods, confectionery bread, processed meat products such as ham, and other food industries. The common type with a cooler and fan is used for freezing processed meats, cooked fried foods, seafood pastes, raw dumplings and steamed cooked foods. IQF (Individual Quick Frozen) freezing uses a technique to freeze products in bulk and is used for rice, cut vegetables, minced meat, shrimp and fish. The type in which cold air is jetted from above and below the conveyor is capable of quick freezing, which is stronger than a normal freezer, and is suitable for freezing relatively large products such as crabs, large-capacity meat packs, and frozen noodles such as pizza and udon. increase.
