Commercial Dairy Pasteurization
Systems
NexAgri batch vats and continuous plate systems support process planning for fluid milk, yogurt bases, cheese milk and liquid beverages. Listed capacities range from 30L batches to 3,000+ L/H continuous flow. Temperature, holding time, cleaning, utilities and documentation are confirmed for the selected product, line and destination market.
Which Pasteurization Method Fits Your Operation?
Compare production volume, product viscosity, changeover frequency and automation needs. Confirm the process duty and site utilities before selecting a configuration.
30L - 1,000L Batch Production
Batch processing for farm dairies and varied product runs. Confirm working volume, agitation, heating method and cleaning requirements for each recipe.
500 L/H - 3,000+ L/H Continuous Flow
Continuous processing with a plate heat exchanger and a regeneration section where specified. Confirm product compatibility, flow rate, controls and downstream packaging requirements.

Engineered Pasteurization Equipment
Compare batch and continuous equipment around product-contact materials, thermal duty, cleaning arrangements and the documentation required for the project.
Batch Pasteurizers (Vat Systems)
Multi-Purpose Heating, Mixing & Fermentation
Jacketed, insulated vats provide heating and mixing for defined batch volumes. Select agitation, heating source and operating sequence around product viscosity and recipe requirements, including changeover and cleaning.
Plate Pasteurizer Units (HTST Continuous)
Continuous Thermal Processing & Heat Regeneration
Plate systems transfer heat between product and utility circuits. A regeneration section can use outgoing processed product to preheat incoming product across the plates. Confirm plate grade, gasket material, flow rate and thermal duty for the product and cleaning conditions.
Why Engineers Choose NexAgri Systems
Specify control components, product-contact materials, cleaning connections and documentation for the selected line. Component selection and equipment supply do not replace process validation or destination-market review.
Flow Diversion Controls
Specify diversion logic, setpoints, response requirements and the return route for the selected continuous process. Confirm operation through commissioning and process validation.
Food-Grade Sanitary Piping
Confirm AISI 304 or 316L material selection, surface-finish requirements, fittings and inspection access against the product and cleaning chemistry. Record the agreed specification in the proposal.
Precision PID Control
Select temperature control, sensor placement, calibration and recording requirements for the process. Confirm the required control tolerance and holding conditions during commissioning.
Automated CIP Integration
Define CIP circuits, supply and return connections, chemical dosing, flow and cleaning sequence for the selected equipment. Cleaning effectiveness requires a suitable procedure and verification.

Thermal System Planning & Operating Costs
Review equipment scope, installation, utilities, cleaning and production schedules together. Compare operating costs using the proposed process and local tariffs.
1. Utility Sizing: Steam, Hot Water & Chilled Water
Specify the heating source, electrical load and cooling conditions for the selected batch vat. Electric or hot-water arrangements may suit sites without dedicated steam; confirm the required duty and connections.
For continuous plate systems, define inlet and outlet temperatures, flow rate, heating and cooling utility conditions, and regeneration duty. Calculate utility demand for that process rather than assuming a fixed energy saving.
2. Sanitation & Clean-In-Place (CIP) Efficiency
Define the cleaning procedure for the product residues and equipment: temperature, chemical concentration, contact time, flow, rinse steps and verification. Confirm compatibility with plates, gaskets and other contact materials.
Confirm plate grade and gasket material, including any specified AISI 316L and EPDM/NBR components, against the product and cleaning conditions. Include disassembly access and replacement parts in the maintenance plan.
3. Process Validation & Data Recording
Agree temperature and holding requirements, flow-diversion logic, calibration, recording and traceability for the selected product and destination. Include commissioning checks, process validation and the required documentation in the project scope.
Build a Process-Specific Budget

Savings and payback require a defined baseline and project-specific assumptions. No fixed recovery period or universal validation outcome is implied.
Pasteurization FAQs
Practical equipment-selection and process-planning answers for commercial dairy pasteurization projects.
How do batch and continuous pasteurization systems differ?
Batch pasteurizers process a defined volume in a jacketed vat and suit operations that handle varied products or smaller production runs. Continuous plate systems process a steady product flow and are evaluated for higher-throughput liquid lines. The right option depends on product range, target output and the planned operating routine.
What products can a pasteurization system be planned for?
The page covers fluid milk, yogurt bases, cheese milk and other liquid beverage applications. Product viscosity, ingredients, target temperature profile and downstream process steps should be confirmed so the thermal process and sanitary equipment scope can be reviewed.
How does heat regeneration work in a continuous plate system?
In a plate heat exchanger, outgoing processed product can transfer heat to incoming cold product across stainless-steel plates. This regeneration stage reduces the heating and cooling load; the final utility requirement depends on the selected process, flow rate and site conditions.
What utilities should be assessed before selecting a pasteurizer?
Confirm the available electrical supply, heating source, chilled-water or cooling-water conditions, water quality, drainage and cleaning arrangement. These inputs help determine the equipment configuration and the utility connections required for the project.
Can pasteurization be integrated with other dairy processing equipment?
Yes. A pasteurization system can be planned with upstream receiving and cooling equipment and with downstream homogenizing, fermentation, storage or filling stages where the process requires them. The final connection scope should be defined in the approved process layout.
How should cleaning requirements be planned?
Cleaning requirements depend on the selected system, products handled and the plant's sanitation procedure. Discuss the proposed cleaning cycle, chemical handling, return route and any CIP equipment needed so the hygienic process can be included in the layout.
What information is needed for a pasteurization quotation?
Provide the product type, target capacity, desired process flow, available utilities, installation space and any equipment that must connect to the system. These details allow NexAgri to review a suitable configuration and quotation scope.
