The plate-type sterilizer is a piece of equipment designed for the aseptic thermal processing of liquid foods and beverages; it is primarily used to sterilize liquids such as dairy products, fruit juices, alcoholic beverages, soy sauce, and vinegar. The system utilizes a plate heat exchanger to execute a closed-loop process comprising heating, holding, sterilization, and cooling. It supports both pasteurization and Ultra-High Temperature (UHT) processing modes, allows for customized system configurations based on specific process requirements, and achieves a heat recovery rate exceeding 94%.

The equipment consists of a product balance system, a plate heat exchange system, a multi-pipeline system, and an automatic control system; the heat exchanger employs corrugated plates to form fluid channels. The core process involves heating the product to a specific sterilization temperature (determined by the chosen process-such as pasteurization or UHT-and the specific material being treated; e.g., pasteurization typically ranges from 62–65°C, while UHT can reach 140°C or higher), followed by sterilization in a holding tube and subsequent cooling via heat exchange before discharge. Constructed from food-grade stainless steel, the unit features a PLC-based automatic control system and Clean-In-Place (CIP) functionality, along with high-temperature alarms and low-temperature recirculation protection. Typical technical specifications include a processing capacity of 1–5 t/h and a steam pressure of 5.0 bar.
