Description
The Negin Steel Alvand Tube Pasteurizer is one of the most essential pieces of equipment used in modern food processing lines, specifically designed for the pasteurization of liquid products such as milk, yogurt drink (Doogh), fruit juice, nectar, sauces, and syrups.
In this system, the product flows through a Tube-in-Tube Heat Exchanger, where it is heated to the required pasteurization temperature using steam or hot water. The product is then held at the target temperature for a specified holding time before being rapidly cooled. This process effectively eliminates harmful microorganisms while extending product shelf life without compromising its flavor, nutritional value, or overall quality.

Advantages of a Tube Pasteurizer Compared to a Plate Pasteurizer
- Offers greater durability, simpler maintenance, and a longer service life.
- Provides superior performance when processing viscous products such as sauces and concentrates.
How Much Does a Tube Pasteurizer Cost?
The price of a Tube Pasteurizer depends on several key factors, each of which directly influences system performance, service life, and production efficiency.
- Production Capacity (Liters per Hour):
Higher processing capacities require larger heat exchangers, more powerful pumps, and greater heating capacity, resulting in a higher overall equipment cost. - Level of Automation:
Manual models offer a more economical solution, while systems equipped with PLC control and HMI touchscreen panels, featuring data logging, automatic temperature control, and integrated safety functions, significantly improve production efficiency and process accuracy.
- Material Grade and Component Brands:
The use of
316Lstainless steel and premium European-brand components increases the initial investment but delivers superior durability, reliable operation, and enhanced hygienic performance. - Optional Features and Customization:
Additional options such as an automatic CIP cleaning system, regenerative heat recovery for improved energy efficiency, and advanced digital monitoring systems substantially increase both the technical capabilities and long-term value of the equipment.
Although a Tube Pasteurizer generally has a higher initial purchase cost than a Plate Pasteurizer, its superior energy efficiency, extended component lifespan, reduced production downtime, and consistent product quality make it a more cost-effective and industrially efficient solution over the long term.
