Qingdao Conqinphi Environmental Technology Group Co., Ltd. brings you a premium Plate and Shell Heat Exchanger for Food Processing, crafted from 316L Stainless Steel and designed to meet the rigorous standards of the dairy industry. As a dedicated manufacturer established in 2015 with a factory spanning 10,000–30,000 square meters and over 200 skilled employees, we understand the critical need for sanitary, efficient, and reliable heat exchange solutions in food and beverage processing. This heat exchanger combines the high thermal efficiency of plate designs with the robust mechanical strength of shell construction, ensuring optimal heat transfer while withstanding demanding processing conditions.
Our model features exceptional easy cleanability, a direct result of its smooth internal surfaces, minimal dead zones, and compatibility with Clean-in-Place (CIP) systems. The 316L stainless steel construction offers superior corrosion resistance against acidic or alkaline food products, while the dairy-grade surface finish prevents bacterial growth and meets strict hygiene regulations. Whether you are pasteurizing milk, concentrating juice, or processing sauces, this heat exchanger delivers consistent performance with low maintenance downtime.
Key Features and Technical Specifications
- Material Excellence: Full 316L stainless steel construction (shell, plates, and connections) for maximum durability and corrosion resistance.
- Sanitary Design: Polished internal surfaces ≤ 0.8 μm Ra, weld-free wetted areas, and self-draining capability to prevent product retention.
- High Thermal Efficiency: Turbulent flow induced by plate geometry, achieving heat transfer coefficients up to 5,000 W/m²·K (depending on fluids).
- Compact Footprint: Up to 60% smaller than traditional shell-and-tube exchangers for the same duty, saving valuable floor space.
- Easy Maintenance: Quick-opening clamps and removable plate bundle allow thorough inspection and cleaning without special tools.
- Versatile Configurations: Single-pass or multi-pass designs available; customizable port sizes and gasket materials (EPDM, Viton, silicone).
- Compliance: Designed in accordance with ASME VIII, PED, and available with HACCP documentation for dairy applications.

Frequently Asked Questions
1. Can this heat exchanger handle viscous products like tomato paste or dairy cream?
Yes, its plate geometry creates turbulent flow even at low velocities, minimizing fouling and maintaining efficiency with viscosities up to 500 cP. For higher viscosities, we offer customized plate patterns.
2. How do I clean the unit after processing dairy?
The exchanger is designed for CIP (Clean-in-Place). Simply circulate a warm alkaline solution (e.g., 1% NaOH at 70°C) followed by acid rinsing. The smooth surface (≤0.8 μm Ra) ensures no residue remains.
3. What is the maximum working pressure?
The standard design handles up to 16 bar. Higher pressure ratings (up to 25 bar) are available with thicker shell plates and ASME-compliant fabrication.
4. Is the gasket material safe for food contact?
Yes, our standard EPDM gaskets meet FDA CFR 21.177.2600 for repeated food contact. We can also provide silicone or FKM/Viton for high-temperature or acidic applications.
5. Can I order multiple units with different heat transfer areas for a single project?
Absolutely. Our modular design allows combining units in series or parallel. Our sales team will help you select the optimal configuration.
6. What certifications do you provide with the product?
We supply material certificates (EN 10204 3.1), pressure test reports, and documentation for HACCP compliance. ISO9001, ISO14000, and other certified management systems are in place.
7. How long is the lead time for a custom-designed unit?
Typical lead time is 4–6 weeks for standard sizes and 8–10 weeks for fully customized designs. Rush orders can be accommodated with our express service.
8. Do you offer installation or on-site support?
Yes, we provide remote technical support and can arrange on-site commissioning for large-scale projects. Our aftersales team is available 24/7 via phone or email.
