Liquid nitrogen is currently the environmentally friendly and economical freezing and medium in the world. With minimal upfront investment, it creates multiple freezing/production lines that can produce high-quality products. Fast freezing in 5 minutes (measured in minutes, not hours) means no need to store a large amount of products, greatly shortening the time to market of your products, simplifying operation, greatly reducing labor and skill requirements for operators, reducing water loss, and improving product quality, And improve the output rate (more products can be operated simultaneously), easily integrated into existing production lines, saving space, cleaning time, small installation costs, and low maintenance costs for your factory. Adopting liquid rapid freezing refrigeration method, introducing German rapid freezing technology, and combining with numerous domestic aquatic product research, equipped with imported rapid freezing technology. The equipment operates stably and is energy-efficient and environmentally friendly. Capable of meeting 24-hour continuous production needs.

The quick freezing machine is used for the quick freezing processing of aquatic products (shrimp, fish fillets, squid, scallops) and various frozen foods (dumplings, soup balls, etc.). All aluminum alloy evaporators have high heat exchange efficiency, fast cooling and quick freezing. The evaporators are arranged along the direction of steel plate operation, with a large windward area, which is not easy to frost and can be continuously produced for a long time. The internal and external supports of the warehouse are made of stainless steel, and the water flushing frost series is clean and hygienic.

1. Check before startup

Before starting work, check the parts of the machine, check the moving parts, and add refrigerant oil to the gearbox. The oil should be heated for more than 60 minutes before the refrigeration compressor starts working.

2. Operation after startup

After starting work, pay attention to the operation between various parts of the machine. If any abnormalities are found, shut down the machine for repair. When starting the compressor, be sure to unload it first and then start the compressor. If two different sounds cannot be heard after pressing the compressor button, the compressor is normal. If only one sound is heard, immediately shut down the compressor and seek relevant technical personnel for repair.

3. Special circumstances

In case of an emergency, press the "Emergency Stop" button to eliminate the tray jam. The conveyor chain must be checked, adjusted and maintained regularly. If any abnormality is found, the conveyor chain must be stopped immediately for troubleshooting. When defrosting, the water must be turned off. During operation, it is not allowed to stop without reason, and the button must be turned to the "0" position to start slowly.
