Low Temperature High Speed Freezer Doors Industrial For Food Factory

18–22 Mm Total Curtain Thickness High Speed Low Temperature Door For Food Factory Freezer Door

The Food Processing Freezer Door is specially designed for frozen food production lines, including meat, seafood, and quick-frozen products, where maintaining strict hygiene and precise temperature control is essential. Installed in cold zones of food factories, this door allows fast and frequent access while minimizing cold air loss, supporting both food safety and production efficiency.

Built for high-demand food processing environments, the freezer door for food factories combines rapid operation, robust construction, and hygienic materials to ensure consistent freezing conditions and compliance with industry standards such as HACCP.

Detailed Feature: Hygienic Design for Food Safety

In food production, hygiene and contamination control are critical. The HACCP freezer door uses smooth, sealed surfaces and anti-bacterial PVC or stainless steel components to reduce dirt accumulation. This design allows frequent cleaning and ensures the freezer environment remains hygienic, while maintaining rapid opening and closing for production efficiency.

Control System (Servo System)

1. Equipped with a dedicated servo control system with a DSP chip at its core. The system determines the door opening height by combining incremental encoder signals from the motor shaft with mechanical home-position switch signals.
2. LED display for real-time fault code indication and diagnostics.
3. Direction protection: If the motor drive wiring is connected incorrectly, the controller immediately reports an error and prevents door operation.
4. Full closed-loop control: Torque loop, position loop, and speed loop for high-precision operation.
5. Vector braking function: The motor can stop precisely at the preset position without the need for an electromagnetic brake, ensuring accurate stopping at limit positions with no deviation.

Drive Motor

1. The drive system adopts a servo motor system, including encoder, braking system, gearbox, and emergency manual opening mechanism.
2. Constant torque output of the servo motor ensures optimal performance of safety devices (suchs as infrared sensors) with fast rebound response.

Safety Features

1. Infrared Safety Protection:
   Photoelectric sensors are installed on both sides of the door frame. When an object is detected under the door, the door remains open. If an object passes underneath during closing, the door opens to the fully open position and descends again after a delay once the area is clear.
2. Bottom Safety Edge:
   If an object is located in the infrared blind zone during closing, the door immediately rebounds to the fully open position upon contact, effectively protecting people and objects and preventing accidents. (Standard configuration)
