Engineered Pasteurization Equipment
Sanitary stainless steel construction meeting international commercial dairy compliance standards.
Batch Pasteurizers (Vat Systems)
Multi-Purpose Heating, Mixing & Fermentation
Engineered for processing variable batch volumes without complex product changeover procedures. Triple-wall insulated jackets provide uniform water bath heating, protecting delicate fat globules and milk proteins from hot-spot scorching.
Plate Pasteurizer Units (HTST Continuous)
High Temperature Short Time with >70% Heat Recovery
Designed for high-capacity commercial processing lines. Features high-efficiency corrugated AISI 316L stainless steel plates that pre-heat incoming cold raw product using outgoing pasteurized product, drastically cutting steam and chilled water utility costs.
Why Engineers Choose NexAgri Systems
We integrate tier-one components and sanitary standards to guarantee continuous thermal stability, easy CIP maintenance, and regulatory compliance.
Compliance Diversion Valves
Automatic three-way flow diversion valves continuously redirect under-heated product back to the balance tank instantly if holding temperature drops below specified setpoints.
Food-Grade Sanitary Piping
All product-contact surfaces utilize mirror-polished AISI 304/316L stainless steel (Ra < 0.4μm) with seamless sanitary tri-clamp fittings for rapid inspection.
Precision PID Control
Advanced micro-processor controllers maintain holding temperatures within ±0.5°C, eliminating heat fluctuations that alter product flavor profiles or burn milk solids.
Automated CIP Integration
Built for automated Clean-In-Place cycles with integrated chemical dosing ports, turbulent high-velocity spray balls, and CIP return pumps for effortless sanitation.

Thermal System Planning & ROI Guide
A thermal processing system is a long-term capital investment. Evaluate utility requirements and ROI payback before finalizing your plant layout.
1. Utility Sizing: Steam, Hot Water & Chilled Water
Thermal processing requires balanced utility infrastructure. Batch Vat systems utilize electric immersion elements or low-pressure hot water boilers, making them suitable for facilities without dedicated steam supply.
By contrast, continuous Plate HTST units rely on steam or high-efficiency water heaters alongside ice water chillers. Because HTST systems utilize multi-stage heat regeneration (pre-heating cold raw milk using hot pasteurized milk), they reduce total thermal energy consumption per liter by up to 70%.
2. Sanitation & Clean-In-Place (CIP) Efficiency
Dairy proteins and fats burn onto plate heat exchangers if water velocities or temperatures are improperly regulated. Automated CIP cycles sanitize internal plate channels and holding tubes at 80°C–85°C with controlled caustic and acid rinses.
NexAgri plate systems are built with sanitary AISI 316L plates and food-grade EPDM/NBR clip-on gaskets, enabling rapid disassembly and maintenance without damaging plate seals.
3. Health Inspection & Data Logging Compliance
Food safety inspectors require verifiable thermal logs proving every drop of product reached minimum pasteurization temperatures for the required holding time. NexAgri HTST systems integrate pneumatic three-way flow diversion valves that instantly divert untreated product back to the balance tank if temperature drops, alongside digital paperless chart recorders for full batch traceability.
