The quick-freezer is to freeze the temperature of the quick-frozen items to -18° in a short time, and quickly pass through the ice crystal production zone (0 to -5 degree range) within 30 minutes to achieve the purpose of reducing the loss of nutrients and reducing the loss of nutrients. Generally, it can be divided into push type, reciprocating type, flat type, fluidized type, tunnel type, spiral type, lifting type, etc.

Working principle:

The push-type quick-freezing machine is mainly composed of a refrigeration system, a propulsion system, an electrical control system and a quick-freezing chamber. Step-by-step movement, in the process of moving, a stable vertical annular low-temperature airflow is formed under the action of the fan and the deflector. This low-temperature airflow exchanges heat with the frozen food moving horizontally, so as to achieve rapid cooling and freezing. process.

The product is conveyed in a spiral way, which occupies a small area and has a large amount of freezing. Therefore, this mechanism can produce quick-freezing equipment with large output. Currently, it is also widely used, mainly in the quick-freezing industry in the food industry.

The lifting type quick-freezing machine is an energy-saving and multi-purpose quick-freezing equipment. The machine has the advantages of energy saving, high degree of automation, small size, stable and reliable performance and so on. It is suitable for quick freezing of small block, strip or granular foods, such as dumplings, steamed buns, spring rolls, glutinous rice balls and other prepared foods.
