Shanghai Jiangxing supplies hygienic gasketed plate heat exchangers for pasteurisation, cooling and heating in food, beverage and dairy processing, with product-contact materials and food-contact documentation specified per order.
What makes a heat exchanger food-grade or hygienic?
A food-grade heat exchanger must ensure product safety and prevent bacterial contamination. This is achieved through specific design and material choices. Product-contact materials are selected per order: 316L stainless steel is the usual plate specification, and gasket compounds such as NBR or EPDM can be specified to food-contact standards where that is requested and confirmed in writing. The design features sanitary connections (like Tri-Clamp) and a plate surface that promotes effective cleaning-in-place (CIP).
Why is a Plate Heat Exchanger ideal for hygienic applications?
Gasketed plate heat exchangers are the preferred choice for most food and beverage applications. Their high thermal efficiency allows for gentle product treatment, crucial for preserving the taste and quality of products like milk and juice. Furthermore, the units can be easily opened for inspection and manual cleaning, and their design creates high turbulence that aids effective CIP, ensuring a hygienic process.
What are common applications in the food & beverage industry?
We supply food-grade plate heat exchangers for a wide range of applications. The most common is pasteurization of milk, juice, beer, and other beverages. They are also used for rapidly cooling wort in breweries, heating and cooling sauces or viscous food products, and for general heating and cooling of process water used in plant operations. Our designs can be tailored for each specific product.
How to select a reliable hygienic heat exchanger supplier?
When selecting a supplier for food-grade equipment, verify their experience in the industry and their knowledge of sanitary standards. Ask which material traceability certificates (MTRs) for steel and conformity documents for gaskets will be issued with the unit; at Shanghai Jiangxing that documentation set is specified in the enquiry and confirmed in writing for the order. We understand the specific requirements of the food industry and can engineer a solution that is both efficient and hygienically safe. Contact Blair at blair@shheatex.com for expert consultation.
What are the details of your sanitary design?
Our hygienic plate heat exchangers feature plates pressed with specific patterns to avoid dead spots and promote high fluid turbulence for better cleaning. The glue-free gasket system ensures a tight seal without crevices where bacteria could grow. We offer a range of sanitary connection types, including Tri-Clamp, DIN, and SMS, to easily integrate with your existing plant piping.

Frequently asked questions
What type of sanitary connections do you offer?
We equip our food-grade heat exchangers with a variety of standard hygienic connections to suit your facility's piping. The most common are Tri-Clamp connections, but we also offer DIN and SMS union-type connections to meet different international sanitary standards.
Are your materials certified for food contact?
Food-contact grade is order-specific. Specify the standard your process requires and we will confirm in writing which plate material (typically 316L stainless steel), gasket compound (NBR, EPDM or other) and food-contact documentation can be supplied for your quality assurance and food safety audits.
Can your heat exchangers be used for milk pasteurization?
Absolutely. One of our primary applications is milk pasteurization. We can design multi-section plate heat exchangers that include heating, cooling, and regeneration sections in a single frame to maximize energy efficiency, meeting the precise time and temperature requirements for effective pasteurization.
How do I get a quote for a food-grade heat exchanger?
To receive a quote, please provide us with details about your product (viscosity, specific heat), the flow rate, and the temperature program (e.g., heating from 4°C to 72°C). Our team will design a hygienic unit tailored to your process and provide a detailed quotation.
