A fully self-developed system, from core components to complete-line integration — evaporator, control system, insulated chamber and CIP cleaning system are all designed and manufactured in-house, ensuring perfectly matched and reliable performance.
Aluminum fin or stainless-steel tube options, inner-grooved copper tube with hydrophilic coating — heat transfer coefficient improved by 20%+.
PLC + color touch screen, auto detection & alarm, remote monitoring and data traceability.
PU high-pressure foamed double-SS sandwich panel, low thermal conductivity, superior airtight insulation.
Optional auto cleaning with full-coverage spray, less downtime, assured food hygiene.
Two-stage temperature zones (pre-cooling + deep-freezing), evaporation temperature -35 to -40°C, core temperature drops to -18°C in 4–60 min at a freezing rate ≥5 cm/h. True IQF: free-flowing particles, no clumping, drip loss below 3% after thawing — preserving colour, texture and nutrition.
Patented symmetrical ring air duct + top static-pressure box, air speed 8–15 m/s uniformly adjustable, freezing-zone temperature uniformity ±1°C; variable fin pitch + VFD fans adjust to load, cutting overall energy use by 15–20% vs conventional units — down to 55–70 kWh per ton of frozen product.
Custom-engineered to your capacity (200–8000 kg/h), floor space and product characteristics (moisture, shape, packaging); belt / mesh-belt / impingement / spiral / fluidized structures selectable, with flexible in-out direction, tiers and stages, and seamless integration with washing, blanching, pre-cooling and packaging equipment.
7×24h technical response with a solution within 48 hours; overseas projects include engineer on-site installation, commissioning and training, with fast-ship spare parts. 12–24 months machine warranty; compressor / PLC / motor covered by OEM brand warranty.
