Full Automatic Tunnel Spray Pasteurizer Enhances Industrial Food Safety

Lead

Industrial sterilization technology, essential for food safety and shelf life, is moving toward intelligence and standardization. Zhucheng Qiangda Machinery Factory has launched the QD-2200 Full Automatic Tunnel Spray Pasteurizer, addressing common challenges such as incomplete sterilization, container breakage, and flavor loss. The system provides a technical breakthrough in thermal processing and supports full-process quality traceability in meat and packaged food production.

Multi-Zone Precise Temperature Control

The QD-2200 features multiple independent temperature zones including preheating, pasteurization, and cooling, with intelligent sensors and heating/cooling units for stepped temperature control. This segmented design reduces thermal stress on glass and tin containers, lowers breakage rates, and preserves nutritional content and flavor while ensuring effective pathogen elimination.

High-Efficiency Spray and Conveyor System

A circulating spray system ensures uniform coverage of all packaged products, improving heat transfer efficiency and eliminating cold spots. The stainless steel mesh conveyor supports variable frequency drive, allowing flexible sterilization times for different products. Protective rails maintain smooth and orderly transport.

Digital Control and Traceability

Integrated PLC and color touchscreen enable storage and recall of multiple process parameters, with real-time monitoring of temperature, belt speed, and alarms. The system automatically generates sterilization process curves, providing data for quality traceability and meeting food safety compliance requirements.

Energy-Efficient Design

The fully enclosed chamber minimizes heat loss, improving energy efficiency, lowering operational costs, and optimizing the workshop environment. High-efficiency cooling ensures that product core temperature drops to a safe range within 30 minutes after sterilization, preventing microbial growth.

Outlook: Closed-Loop Quality Control

Zhucheng Qiangda Machinery Factory will continue to advance tunnel spray pasteurization technology, helping clients establish a closed-loop quality control system across pre-sterilization, sterilization execution, and post-sterilization stages. The QD-2200 safeguards food safety while enhancing industrial competitiveness in the food processing sector.
