Food Grade Sanitary Water Desalination System PLC Automatic Control Stainless Steel 304 316 Construction
This food-grade reverse osmosis desalination equipment is specifically designed for raw material mixing, syrup blending, beverage dilution, and food liquid preparation in food processing plants. It efficiently removes calcium, magnesium ions, soluble salts, heavy metals, and impurities from raw water. The low-salinity purified water stabilizes food taste, prevents precipitation and turbidity in finished products, and meets national food safety water standards for food production.
- Full Food-Grade Sanitary Configuration: All water-contact parts utilize 304/316L stainless steel and food-grade RO membranes, eliminating toxic coatings or secondary pollution. Meets food sanitation requirements for beverage, jam, condiment, and dairy production.
- Consistent Product Quality: Excessive salt and hardness ions can react with fruit acid, protein, and pectin, causing sediment, cloudy liquid, and inconsistent flavor. Desalted pure water eliminates these defects and ensures uniform product taste in mass production.
- Intelligent Automatic Operation: Equipped with PLC full-automatic control system featuring regular automatic membrane flushing, pressure/liquid level fault alarm, and power-off memory function. Supports 24-hour continuous water supply to match non-stop food production lines.
- Integrated Compact Design: Pretreatment filters and RO main unit are assembled on an integrated stainless steel frame, saving equipment room space and simplifying installation and pipeline connection.
- Reduced Long-term Production Costs: Pure soft desalted water prevents frequent descaling of mixing tanks, sterilizers, and filling pipelines, reducing chemical cleaning and maintenance costs while minimizing finished product waste caused by hard water precipitation.
- Pretreatment: Removes sediment, residual chlorine, and hardness to protect RO membrane
- RO Desalination Host: Deeply filters salt ions to produce low-conductivity process water
- Optional Post Disinfection: UV sterilizer to inhibit bacteria and guarantee sanitary water
