Industrial dual door shock blast chiller / Vertical iqf shrimp freeze equipment air blast freezer
The ultra-low temperature quick-freezer is mainly used for rapid cooling and freezing of food, and can quickly lock food nutrients. Maintaining the freshness and quality of food has a significant effect. Compared with conventional cold storage, our ultra-low temperature quick freezer has the characteristics of faster freezing, more energy saving and easy operation. 1) The compressor and refrigeration accessories of the unit use well-known brands to ensure the efficient and reliable operation of the unit. 2) The unit is equipped with a variety of protection devices to ensure safe use. 3) The operating system of the unit adopts programmable and remote monitoring electronic control, with excellent performance, safety and reliability, and simple operation. 4) The unit completes the system pipeline assembly and the installation and debugging of the electrical control circuit in the factory, and the installation on site is simple and convenient. 5) The unit and the cabinet are integrated, with compact structure and ultra-low noise.
Structural features and working principle
2.1 Unit structure The unit consists of five systems: refrigeration system, cooling water system, air duct system, evaporator end
and electric air system. 2.1.1 Refrigeration system The refrigeration system of the ultra-low temperature quick freezer is
composed of a high temperature level refrigeration system and a low temperature level refrigeration system. The heat exchange tube
Using high-efficiency tubes, the heat exchange capacity is better. The condenser has compact structure, small footprint and high
heat transfer coefficient. Detachable structure for easy maintenance and cleaning. The evaporator adopts the copper tube aluminum
fin evaporator designed by the company (or aluminum plate), high-efficiency copper tube is used, and the heat exchange effect is
good. Expansion valve, filter drier, sight glass, Expansion tank, regenerator and other accessories, all adopt Internationally
renowned brand products can ensure the efficient and reliable operation of the system. 2.1.2 Electrical system The unit adopts
programmable controller to automatically complete the operation and protection functions of the unit. Our company's unit selection
The programmable controller has the advantages of small size, light weight, high reliability, large storage capacity and many
control points. Coupled with the unique analog input expansion module of the controller, the control accuracy of the system is
greatly improved. According to According to user requirements, the programmable controller can be equipped with a dedicated
communication interface, so as to realize the remote control and centralized real-time control of the unit. control, so that the
unit can flexibly cooperate with the building automatic control system to realize multi-directional automatic intelligent control.
2.1.3 Cooling water system The water system consists of condenser, cooling tower, circulating water pump, stop valve, check valve,
filter and pipeline.
Nominal cooling conditions: supply air temperature -54°C, return air temperature -50°C; cooling water inlet temperature 30°C, outlet water temperature 35°C. The applicable ambient temperature range of this unit is: 5℃±1℃～43℃±1℃, and the cooling water inlet temperature range: 10～35℃
