Qingdao Conqinphi Environmental Technology Group Co., Ltd. is a leading manufacturer specializing in advanced heat exchange solutions for the food and dairy industry. With over 8 years of engineering experience and a modern factory spanning 10,000–30,000 square meters, we deliver high-performance equipment that meets the strictest hygiene and safety standards. Our PLC Controlled Automatic Plate Heat Exchanger for Dairy is designed to handle demanding processes at 15 Bar and 120°C, with precise flow regulation controlled by an intelligent PLC system. This unit ensures consistent product quality, energy efficiency, and minimal downtime, making it an ideal choice for dairy plants worldwide.
The heat exchanger combines robust construction with smart automation. The PLC control unit monitors and adjusts flow rates in real-time, ensuring optimal heat transfer while maintaining the delicate properties of dairy products. The unit is fully automatic, reducing manual intervention and operator errors. It is built to withstand continuous operation in harsh environments, with all wetted parts made of high-grade stainless steel to resist corrosion and facilitate cleaning-in-place (CIP).
Key Features & Technical Specifications
- PLC Control with HMI Interface: User-friendly touchscreen allows easy parameter setting, real-time monitoring, and data logging. Supports remote access and integration with plant SCADA systems.
- Automatic Flow Regulation: PID-controlled modulating valves ensure precise flow adjustment based on temperature and pressure feedback, maintaining ±0.5°C temperature accuracy.
- High Pressure & Temperature Rating: Designed for 15 Bar operating pressure and 120°C continuous service, suitable for pasteurization, sterilization, and cooling processes.
- Sanitary Design: All product contact surfaces are polished to Ra ≤ 0.8 μm, with no dead ends. Gaskets are made of FDA-approved EPDM or Viton, ensuring compliance with dairy industry standards.
- Energy Efficient: Counter-current flow arrangement maximizes heat recovery, reducing utility costs by up to 30% compared to traditional shell-and-tube exchangers.
- Modular Construction: Plate packs can be easily expanded or reconfigured for future capacity changes. Frame is made of carbon steel with epoxy coating for durability.
