What Makes a Heat Exchanger Food-Grade?

Food-grade heat exchangers are designed and manufactured with materials, processes, and standards that ensure compliance with food safety regulations such as FDA, CE, and 3-A sanitary standards. Key requirements include:

1. Material Selection: Stainless steel (e.g., 304L or 316L) is commonly used for its corrosion resistance, non-toxicity, and easy cleaning properties.
2. Surface Finish: Polished surfaces with a low roughness value (e.g., Ra < 0.8 µm) to prevent microbial buildup.
3. Hygienic Design: Seamless construction, no dead zones, and CIP (Clean-In-Place) compatibility to maintain hygiene.

Why Spiral Plate Heat Exchangers for Food Applications?

Spiral plate heat exchangers offer unique benefits that make them a top choice in the food industry:

1. Superior Heat Transfer Efficiency:
   • The spiral channels ensure optimal thermal performance, even with viscous fluids like syrups, dairy, or sauces.
2. Compact and Space-Saving Design:
   • The high surface area within a compact footprint makes them ideal for food production facilities with space constraints.
3. Self-Cleaning Properties:
   • The spiral flow minimizes fouling, reducing downtime for cleaning and ensuring continuous operation.
4. Customizable Design:
   • Boyu offers options tailored to the specific needs of food processors, including detachable designs for thorough manual cleaning.

Applications of Food-Grade Spiral Plate Heat Exchangers

1. Pasteurization:
   Efficient heat transfer for milk, juice, and other liquid foods, ensuring they meet safety standards without compromising quality.
2. Cooling and Heating:
   Handling temperature-sensitive products such as chocolate, cream, and beer during production.
3. Condensation and Evaporation:
   Processing applications like sugar concentration or fruit puree production.
4. Energy Recovery:
   Capturing heat from wastewater or other processes to enhance energy efficiency.
