What is the working principle of the plate freezer?

Among all quick-freezing equipment, the plate freezer is very common in quick-frozen food processing plants. It is a kind of quick-freezing equipment that is both efficient and energy-saving. The plate freezer adopts the contact type flat cold plate with the unique structure of the upper and lower double layers to ensure that the frozen product is fast frozen, the temperature is uniform, and the surface is flat. It adopts a floating cold plate moving device and built-in precision sensors to meet the needs of different specifications of frozen products and ensure that the frozen products The contact is good, and there is no worry of rupture. In the food processing industry, the plate freezer is mainly used for the processing of various small block, strip, and granular foods such as steamed buns, glutinous rice balls, dumplings, etc. It has excellent performance and is widely used.

Theoretically, the specific working principle of the plate freezer can be recorded as follows: the plate freezer is connected with an automatic conveying system, which can place the frozen product tray with the food to be frozen on the horizontal conveyor chain of the quick-freezer, and the frozen product tray enters with the conveyor chain The lifting track in the quick-freezing chamber makes a step-by-step lifting movement. When the frozen product tray rises to the bridge position, the pusher of the plate freezer pushes the frozen product tray on the lifting track to the lowering track, and then the frozen product tray runs along the descending track to the horizontal conveyor chain, and the conveyor chain transfers the frozen products The tray is sent out of the quick freezing chamber. When the food is carried out in the quick-freezing room with the frozen product tray, the strong cold air generated by the refrigeration system forms a stable horizontal annular low-temperature air flow under the action of the fan and the deflector, and exchanges heat with the frozen food in the vertical movement. The frozen food realizes rapid cooling and freezing, completing the freezing process. In the above working process, the plate freezer exhibits several characteristics.

The characteristics of the plate freezer are as follows:

l Small footprint, stable and reliable performance

l High-efficiency and energy-saving new products

l Good quick-freezing effect

Small footprint, stable and reliable performance

The plate freezer is connected to the three-dimensional structure of the conveying system, and the whole box is layered according to the upper and lower layers, which maximizes the use of space, and the appearance is neat and convenient for placement. In addition, the plate freezer adopts the contact type flat cold plate with the unique structure of the upper and lower double layers to ensure that the frozen products are quickly frozen, the temperature is uniform, and the surface is flat. The floating cold plate moving device is used, and the built-in precision sensor meets the needs of different specifications of frozen products to ensure freezing. The product is in good contact, and there is no worry of rupture.

High-efficiency and energy-saving new products

The excellent plate freezer adopts an advanced power system, which can save about 30-40% of electricity compared with the same type of products and reduce production costs.

Good quick-freezing effect

The plate freezer adopts a compact structure and optimized air duct design, which can quickly and effectively cool the food, ensuring that the moisture and quality of the food are completely preserved. The plate freezer has the best quick-freezing effect, and the ice crystals produced by freezing are small and help maintain the texture of the food. This also prevents the loss of moisture and achieves no loss. Therefore, the plate freezer can maintain the original color, flavor and quality of food to the greatest extent.

The above is the specific working principle of the plate freezer, but factory workers do not need to fully understand these complex theoretical issues when operating. The plate freezer uses a combination of PLC control and humanized interface, flexible control, simple operation, and can meet the needs of most manufacturers.
