The plate pasteurizer is a piece of thermal processing equipment suitable for the continuous treatment of low-viscosity liquid foods with low particulate content. Its key advantages include high heat transfer efficiency, effective heat recovery, a compact design, and rapid temperature response; it is commonly used in the production of milk, clear juices, and low-viscosity beverages. Its primary limitations stem from the narrow flow channels between the plates. For products with high viscosity or those containing large pulp, fibers, or solid particles, the plate-based structure may encounter issues such as increased pressure drop, clogging, or cleaning difficulties.
Pasteurizers achieve controlled thermal treatment of food products by regulating heating temperatures, holding times, and cooling processes. Therefore, when evaluating a pasteurizer, it is essential to consider its operating mode, heat exchange structure, processing requirements, and the packaging state of the product.
