As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. specializes in high-performance heat exchange solutions for the food and dairy industry. Our 316L Stainless Steel Plate Heat Exchanger is engineered specifically for dairy processing, combining superior corrosion resistance with full CIP (Clean-in-Place) compatibility. With over 9 years of manufacturing experience and a 10,000–30,000 m² factory, we deliver reliable, food-grade equipment that meets the rigorous hygiene and efficiency demands of modern dairy plants.
This plate heat exchanger is constructed from premium 316L stainless steel, offering excellent resistance to chlorides, acids, and high-temperature cleaning agents. It is designed to handle pasteurization, cooling, heating, and regeneration processes for milk, cream, yogurt, and other dairy products. The compact design ensures maximum heat transfer efficiency while minimizing product hold-up volume, reducing waste and energy consumption.
Key features include:
- Food-Grade Construction: All product contact surfaces are made of 316L stainless steel, with smooth surfaces (Ra ≤0.8 μm) to prevent bacterial growth and facilitate cleaning.
- CIP Cleaning Compatible: Fully supports clean-in-place procedures with chemical and temperature resistance, ensuring rapid sanitation without disassembly.
- High Thermal Efficiency: Corrugated plate design creates turbulent flow, achieving heat transfer coefficients up to 6,000 W/m²·K, reducing energy costs.
- Modular & Scalable: Frame and plate configuration can be customized to meet specific capacity and pressure drop requirements, from small pilot plants to large industrial lines.
- Durable Gaskets: Food-grade EPDM or NBR gaskets are clip-on or glue-free, simplifying replacement and extending service life.
- Leak-Free Design: Double gasket sealing with leakage detection channels prevents cross-contamination and ensures product safety.

Frequently Asked Questions (FAQ)
-
Q: Can this heat exchanger handle whole milk pasteurization?
A: Yes, it is designed for various dairy products including whole milk, skim milk, cream, and yogurt. The 316L stainless steel and food-grade gaskets ensure product purity and efficient heat transfer. -
Q: Is the CIP cleaning compatible with caustic and acid solutions?
A: Absolutely. The 316L material and EPDM gaskets resist common CIP chemicals (NaOH, HNO3, etc.) at recommended concentrations and temperatures up to 95°C. Always follow our cleaning guidelines. -
Q: What is the typical lifespan of the gaskets?
A: With proper CIP cycles and regular inspection, EPDM gaskets can last 2–3 years in dairy service. We offer replacement gasket kits for easy maintenance. -
Q: Can I get customized plate dimensions or frame size?
A: Yes, we offer custom designs based on your flow rate, pressure drop, and temperature requirements. Contact our sales team with your process parameters. -
Q: Do you provide certification documents for the material?
A: Yes, we can provide 3.1 material certificates for the 316L plates, as well as HACCP and ISO certificates upon request. Certain certifications are available for an additional fee. -
Q: What is the maximum number of plates in one frame?
A: This depends on the frame model. Our standard frames can accommodate up to 300 plates, but we can design larger frames for high-capacity applications. -
Q: How do I prevent cross-contamination between product and service fluid?
A: Our heat exchangers feature double gasket sealing with a leakage detection groove. If a gasket fails, the leak is visible externally, preventing mixing of fluids. -
Q: What is the lead time for a standard unit?
A: Typically 15–25 working days after order confirmation, depending on complexity and quantity. For urgent orders, please inquire about expedited service.
