Temperature Control Panel for Beverage Pasteurization and Cooling Tunnel

Product Specifications

Technical details and manufacturing context for Temperature Control Panel

Definition

The Temperature Control Panel is a critical component of the Integrated Beverage Pasteurization and Cooling Tunnel System, providing operators with real-time monitoring and precise control over heating and cooling zones. It ensures beverages reach and maintain required pasteurization temperatures for safety while managing rapid cooling phases to preserve quality and extend shelf life. The panel receives temperature data from sensors (e.g., thermocouples, RTDs) placed throughout the tunnel's heating and cooling zones. This data is processed by a programmable logic controller (PLC) or similar unit within the panel. Operators set target temperatures and control parameters via the interface. The panel then outputs control signals to actuators—such as steam valves, heating elements, or refrigeration compressors—to adjust energy input and maintain the desired thermal profile as products move through the tunnel. The panel is housed in a stainless steel enclosure with a polycarbonate display screen, and internal wiring is copper. It supports a rated voltage of 220–240 V AC (single phase, 50/60 Hz) per IEC 60204-1, with power consumption not exceeding 150 W (excluding connected sensors/actuators). The temperature control range covers 0–150 °C for pasteurization and cooling zones, with an accuracy of ±0.5 °C when using PT100 sensors per IEC 60751. The control loop update rate is 100 ms for fast response. It offers 8–32 configurable control channels per zone. Input and output signals are 4–20 mA per IEC 60381, and the communication interface is RS485 with Modbus RTU per IEC 61158. The panel operates in ambient temperatures of 0–50 °C and can be stored at -20–70 °C, with a non-condensing humidity range of 10–90% RH per IEC 60068-2-78. It has an ingress protection rating of IP54 per IEC 60529, and dimensions are 600×400×200 mm (W×H×D). Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The panel receives temperature data from sensors (e.g., thermocouples, RTDs) placed throughout the tunnel's heating and cooling zones. This data is processed by a programmable logic controller (PLC) or similar unit within the panel. Operators set target temperatures and control parameters via the interface. The panel then outputs control signals to actuators—such as steam valves, heating elements, or refrigeration compressors—to adjust energy input and maintain the desired thermal profile as products move through the tunnel.
