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.
Pasteurizers are critical for heat-treating liquid foods. Abnormalities in temperature, flow, pressure, cooling, or cleaning can cause incomplete pasteurization and food safety risks. When issues arise, verify process parameters first, then troubleshoot from simple to complex. Before inspection, stop feed, shut off utilities, and release pressure. Never disassemble under pressure, heat, or power, and never bypass alarms or safety interlocks.
