HTST PMO Pasteurizer Thermoplak™

The Certified Gateway to the United States Dairy Market

The Certified Gateway to the United States Dairy Market The Thermoplak™ is a continuous flow pasteurization system engineered to meet the rigorous Pasteurized Milk Ordinance (PMO) standards required for U.S. export. This unit isn't just a heater; it is a fully integrated legal "kill-step" system that ensures total safety and regulatory compliance. Performance & Efficiency (Rendimiento) While many systems struggle with utility costs, the Thermoplak™ is designed for maximum thermal recovery. System Throughput: Available in sizes ranging from 265 - 7,925 GPH (1,000 - 30,000 L/hr). Thermal Regeneration: Achieves up to 95% regeneration. Note: Not every pasteurizer on the market can reach this level of efficiency; this high rate significantly reduces the load on your boiler and cooling systems. Applications: Fluid milk, dairy formulas, flavored milk, creams, ice cream bases, yogurt bases, concentrates, juices, syrups, flavored beverages, whey, water, and more.

APPLICATIONS

STLR control panel of the HTST PMO Thermoplak™ Pasteurizer

PMO REGULATORY COMPLIANCE

SAFETY THERMAL LIMIT RECORDER-CONTROLLER (STLR)

STLR (Safety Thermal Limit Recorder) integration — sealed and shielded — acting as the process's 'legal brain', irrevocably recording temperature and every flow diversion event.

REFERENCE INDICATING THERMOMETER (MIG/RTD): Certified reference indicating thermometer, strategically located next to the control probe for immediate visual verification and system calibration.

Flow Diversion Device FDD valve of the HTST PMO Thermoplak™ Pasteurizer

PMO REGULATORY COMPLIANCE

FLOW DIVERSION DEVICE (FDD) WITH LEAK DETECTION

Double-stem Flow Diversion Device (FDD) with 'Fail-Safe' logic and visible leak detection ports, guaranteeing that not a single drop of sub-lethally treated product reaches the cooling section.

PMO REGULATORY COMPLIANCE

DIFFERENTIAL PRESSURE CONTROL IN REGENERATION

Positive differential pressure safety system. The PLC logic and transducers guarantee that pasteurized product always has greater pressure than raw product, protecting the final product against cross-contamination in the regenerator.

The system will activate the flow diversion valve if pressure in the raw milk side of the regenerator exceeds a minimum established below the pressure on the pasteurized milk side, thus preventing possible raw milk leaks into the pasteurized milk.

Ascending slope holding tube of the HTST PMO Thermoplak™

PMO REGULATORY COMPLIANCE

HOLDING TUBE WITH ASCENDING SLOPE

Holding Tube isometrically designed with continuous ascending slope for air elimination, ensuring the exact residence time of every milk particle.

PMO REGULATORY COMPLIANCE

TIMING PUMP CONTROLLED BY MAGNETIC FLOW METER

Positive displacement pumping system with speed controlled by magnetic flow meter, ensuring that flow rate never exceeds the validated limit for pasteurization.

PMO REGULATORY COMPLIANCE

ATMOSPHERIC PROTECTION SYSTEM (VACUUM BREAKER)

Integration of Sanitary Atmospheric Vacuum Breaker Valve (PMO type), strategically located at the highest point of the pasteurized return line.

Guarantees instant gravity drainage of the plates when the equipment stops, eliminating the 'siphon effect' that retains residues. This ensures strict compliance with positive differential pressure (cross-contamination safety) and maximizes CIP cleaning cycle efficiency by preventing chemical dilution.
