The main body of the equipment-including the box body, the door and the heat insulation layer are made of AISI 304 stainless steel;

Internal surface roughness-matt;

Thermal insulation material—The thermal insulation layer is a multi-layer composite structure of ultra-low temperature thermal insulation material of BASF; double-sided stainless steel polyurethane high-pressure foaming, good thermal insulation performance, easy to clean, ensure food hygiene and safety, and avoid excessive reproduction and breeding of microorganisms.

The door body is sealed-double-sealed, special low-temperature resistant silicone rubber imported from France, and the door sealing strip is equipped with an anti-freeze heating system to ensure that the door can be opened freely.

The box body is strengthened and reinforced, which can reliably carry the weight of the workpiece. The special design can make the wind direction and air flow in the box unobstructed and ensure the temperature in the box is consistent.

The introduction of the HACCP hygiene and safety concept, the all-stainless steel internal structure and enclosure structure fully consider the ease of cleaning, maintenance, management, etc., easy to operate, and fully meet the food hygiene and safety requirements for equipment.

Reasonable access doors and access channels for easy maintenance and internal cleaning

Use hydration defrosting or electrolysis defrosting (optional) to ensure the liquid nitrogen atomization system is clean and hygienic, and to avoid bacterial growth,

There is a high-temperature disinfection device in the box, the temperature can reach +121℃ (optional) to ensure that the bacteria are fully killed.

The transmission system adopts a double-pitch chain transmission device, equipped with a brand-name reducer and frequency converter to ensure the stability and reliability of the transmission system, and has a special design to prevent the mesh belt from running off and the chain jumping.
