Pasteurizers
A Pasteurizer is a critical thermal processing system used in the food and beverage industry to eliminate harmful microorganisms while preserving product quality and extending shelf life. The pasteurization process involves controlled heating, holding, and rapid cooling, ensuring that pathogenic bacteria are neutralized without compromising flavor, texture, or nutritional value.
At Rahavard Saei, we specialize in the design and manufacturing of high-performance pasteurization systems, tailored for dairy, juice, soft drinks, eggs, and other liquid food applications. Our pasteurizers are built with high-grade stainless steel (SS 304, SS 316) and feature advanced temperature control systems for precision and efficiency.

How It Works
The pasteurization process involves three critical phases:
- Heating Phase – The liquid product is heated to a specific temperature using a plate or tubular heat exchanger. The heat supply can be direct (steam injection) or indirect (hot water or thermal oil heating).
- Holding Phase – The product is maintained at the target temperature within the holding tube (10mm – 101mm diameter) for 3 to 300 seconds, depending on the required microbial reduction level.
- Cooling Phase – The pasteurized product is rapidly cooled using a heat exchanger, ensuring minimal thermal degradation while preventing bacterial regrowth.
Main Components of a Pasteurizer
- Balance Tank – Regulates product inflow and maintains steady operation.
- Filters & Product Pump – Ensures clean and consistent flow through the system.
- Heat Exchange Unit – Optimized for efficient thermal transfer and energy savings.
- Holding Tube – Maintains the required temperature for the necessary duration.
- Three-Way Automatic Valve – Controls the flow between pasteurized and non-pasteurized product pathways.
- Hot Water System – Can be direct or indirect heating, depending on process needs.
- Control System – Available in ON-OFF, PID, and PLC-based configurations for automated monitoring and precise control.
Proper pasteurization design is critical in maintaining product safety, efficiency, and compliance with industry regulations. Rahavard Saei’s pasteurizers ensure consistent processing, energy efficiency, and long-term reliability, reducing operational costs while maximizing food safety standards
