HTST Continuous Plate
Pasteurizers
NexAgri HTST plate pasteurizers serve continuous dairy and liquid-beverage processing lines, with listed flow capacities of 500 to 3,000+ L/H. Plate material, gaskets, thermal duty, control response and documentation are selected around the product, flow rate, utilities and destination requirements.
The listed ranges support initial selection. Confirm the product, holding duty, material finish, control components and cleaning scope for the quoted unit. Temperature and time ranges are not validated recipes for every product.
Why Commercial Dairies Choose Plate HTST
Compare throughput, regeneration duty, diversion controls and cleaning arrangements against the planned product and plant utilities.
Thermal Energy Recovery
Outgoing processed product can preheat incoming cold product across separate plate channels. The recovery duty and utility demand depend on product properties, temperatures, flow and exchanger selection.
Continuous Flow Rate
Match the selected flow rate to product properties, holding requirements and downstream storage or filling. Include startup, changeover and cleaning in the operating schedule.
Automatic Flow Diversion
A pneumatic diversion valve can return product when monitored conditions fall outside the approved process settings. Specify response, interlocks, return routing and commissioning tests for the selected line.
Processing Scale Configurations
Select the frame size and utility interface around product and output requirements. Table values describe listed configurations; confirm regeneration at the specified temperatures and flow, and confirm controls and CIP scope before ordering.

Engineering Deep Dive
Review the listed corrugated-plate construction, materials and connections for the selected product. Confirm surface finish, gasket compatibility, diversion response and the required documentation by model and destination.
Total Cost of Ownership (TCO) & Planning Guide
Assess the complete heating, cooling and cleaning duty of the proposed line. Compare equipment, installation and operating costs using local tariffs and the planned production schedule.
1. How Heat Regeneration Reduces Utility Consumption
Calculate heating and cooling demand from product flow, properties, inlet temperature and the approved process setpoints. Include the available utility temperatures and capacities in exchanger selection.
Regeneration transfers heat from outgoing product to incoming product across separate plate channels. The recovered duty reduces external heating and cooling loads; calculate the achievable recovery for the specified process rather than assuming a fixed saving per liter.
2. CIP Cleanability & Anti-Fouling Plate Maintenance
Product residues can affect plate flow and heat transfer. Monitor operating performance and define inspection and cleaning intervals for the product, duty and operating hours.
Specify CIP temperature, chemical concentration, flow, contact time and rinsing for the product residues and material compatibility. Verify cleaning results and plan plate-pack inspection and gasket service; CIP does not remove every need for disassembly.
3. Process Validation & Data Recording
Define the required temperature, flow and diversion records, calibration, access controls and retention requirements for the selected process and destination. Confirm the recorder and export functions in the equipment scope and include commissioning and process-validation checks.
Compare Thermal Duty & Operating Costs
- Process dutyProduct, flow, inlet and outlet temperatures, holding requirements and regeneration design.
- Utilities & installationHeating and cooling sources, connections, pumping, controls and commissioning.
- Operating scheduleProduction hours, changeovers, CIP inputs, local tariffs, labor and maintenance.
- Validation & documentationAgreed tests, calibration, records and destination requirements.
Compare against a defined existing process. Recovery, savings and payback depend on the selected duty and project costs.

Practical engineering answers for dairy processors, beverage plants and project procurement teams.
What capacity should I choose for a continuous plate pasteurizer?
Size the line around the required hourly output, the peak production window and the capacity of downstream storage or filling equipment. This page covers 500 to 3,000+ L/H configurations: compact skid units are listed at 500 to 1,000 L/H, while industrial modules cover 2,000 to 3,000+ L/H. Confirm the product type, target flow rate and planned operating hours when requesting a configuration.
How does heat regeneration work in an HTST plate pasteurizer?
Outgoing processed product transfers heat to incoming cold product across separate plate channels. Listed references are 65% to 70% for the standard skid and over 75% for the four-stage module; confirm these at the agreed product, flow and temperature duty. Recovery percentage is not a guaranteed reduction in total plant utility cost.
Do I need a steam boiler for a plate pasteurizer?
Not in every case. The 500 to 1,000 L/H standard HTST skid can be configured for electric hot water or boiler steam. The 2,000 to 3,000+ L/H industrial module is specified for an industrial steam-boiler connection. Utility selection should be checked against the site's available electrical supply, steam capacity, chilled-water system and production schedule.
What pasteurization temperature and holding time can the system use?
The page lists HTST operating parameters of 72 to 85°C with a 15 to 20 second holding time. The required setpoint must be selected for the specific product and the applicable local food-processing requirements. The system's temperature control, holding tube and flow-diversion valve are configured around the approved processing parameters.
Can a homogenizer or cream separator be integrated in the process line?
Yes. The standard skid has an optional inline-homogenizer bypass valve, and the industrial module includes a pre-piped interface specified at 60 to 65°C. Confirm the required product viscosity, homogenization pressure, separator duty and line flow during process design so the connection and control sequence can be matched to the full dairy processing line.
How are the plates cleaned and maintained?
The unit is designed for CIP connection. It uses AISI 316L corrugated plates with a Ra ≤ 0.4 μm surface specification, sanitary Tri-Clamp connections and clip-on EPDM or NBR gaskets. A suitable cleaning recipe, solution temperature, flow rate and inspection interval should be set for the processed product; plate and gasket service can then be planned around operating hours and cleaning results.
