In modern dairy and beverage production, precision is the foundation of food safety. Our Fully Automatic Plate Type Pasteurizer is an advanced HTST system (High Temperature Short Time) engineered to deliver consistent sterilization while preserving the sensory qualities of your product. Controlled by a sophisticated PLC-based beverage pasteurizer with a touch screen interface, this unit eliminates human error by automating the entire thermal cycle. Whether you are processing fresh milk, fruit juices, or tea, our automatic plate-type pasteurizer ensures that every drop meets the most stringent international hygiene standards. By integrating Precision PID Temperature Control, the system maintains a stable pasteurization environment with a deviation of less than 0.5°C.

How It Works:
Our continuous flow pasteurization process is divided into four critical stages to ensure safety and energy efficiency:
- Inlet & Pre-heating: The raw product enters the balance tank and is pumped into the PHE Pasteurizer. Here, it undergoes regenerative heating using the energy from the already-pasteurized hot product.
- Sterilization: The product reaches the target temperature in the heating section. The PLC-controlled pasteurizer monitors the “Holding Tube” to ensure the liquid stays at the required temperature for the exact duration needed to eliminate pathogens.
- Safety Diversion: If the Precision PID Temperature Control detects a drop below the setpoint, an automatic flow diversion valve redirects the product back to the balance tank, preventing unsterilized liquid from reaching the cooling stage.
- Cooling & Recovery: This is an energy-saving automatic plate pasteurizer with 90% heat recovery. The outgoing hot liquid pre-heats the incoming cold liquid, drastically reducing steam and cooling water consumption.
Applications:
This full auto milk plate pasteurization system is not limited to dairy. Its flexible configuration makes it an ideal thermal treatment system for:
- Dairy: Liquid milk, yogurt base, and cream.
- Beverages: Clear and pulpy fruit juices, iced tea, and energy drinks.
- Brewing: Craft beer and cider stabilization.
- Liquid Egg: Targeted pasteurization for whole eggs or whites.
Why Choose our PLC Controlled Pasteurization Unit?
When investing in a heat exchanger sterilizer, reliability and operational costs are the two most important factors.
- Superior Energy Efficiency
Standard systems often waste significant thermal energy. Our design is an energy-saving automatic plate pasteurizer with 90% heat recovery, allowing you to recycle the majority of your thermal load and lower your carbon footprint. - Intuitive PLC Automation
The PLC-based beverage pasteurizer with touch screen provides real-time data logging, trend analysis, and fault alarms. This allows operators to monitor the entire HTST system from a single station, ensuring full traceability for food safety audits. - Hygienic Excellence
Safety is non-negotiable. Our food-grade CIP cleanable pasteurizer features high-turbulence plate patterns that prevent scaling and ensure deep cleaning during the CIP cycle, maintaining a sterile environment day after day.
Packaging Process
FAQ
Q: Can this system handle different flow rates?
A: Yes. While it is a continuous flow pasteurization unit, the frequency inverter-controlled pumps allow for adjustable flow rates to match your filling line speed.
Q: What makes a Plate Pasteurizer better than a Tubular one?
A: A PHE pasteurizer is more compact and offers higher heat transfer efficiency for low-viscosity liquids. It is also easier to expand by adding more plates to the frame.
Q: Is the data logging compliant with food safety regulations?
A: Absolutely. The PLC-controlled pasteurizer records all temperature fluctuations and valve positions, providing the digital “paper trail” required by modern food safety standards.
