  In static tube pasteurizers, the flowing product is heated and cooled by counter-current flow of heating and cooling fluids. However, the static design limits the mixing of the heating medium, which may lower its energy efficiency. The static tube pasteurizer is typically less flexible and suitable for processing homogenous products with fixed volumes.

• Continuous Combination Cooker Cooler

  This machine features a unique triangular profile that offers excellent heat transfer performance and product recovery. The combination of cooking and cooling processes in a single unit helps to streamline production, enhance product quality, and minimize contamination risk.

• Scraped Surface Pasteurizer

  The scraped surface pasteurizer is ideal for processing high-solid, viscous, and sticky products. It uses a rotating scraper to continuously scrape the heating surfaces, preventing fouling and ensuring uniform heating. This type of pasteurizer also provides quick cooling after heating, which is crucial for preserving product integrity and quality.

• Plate Pasteurizer

  Using stainless steel plates, plate pasteurizers achieve efficient heat transfer for liquid and semi-liquid food. Products flow between the plates for precise heating and cooling, which helps to meet temperature and time standards for pasteurization. In addition, plate pasteurizers are more compact than tubular ones and suitable for various food industries.

• HTST (High Temperature Short Time) Pasteurizer

  HTST pasteurizers heat liquids to a minimum of 161°F (72°C) for at least 15 seconds. They are commonly used in the dairy, juice, and liquid food industries. By rapidly heating and cooling the products, HTST pasteurizers preserve the nutrients and natural flavors, which significantly enhance the shelf life of food products.

• networked online pasteurization Control

  This advanced pasteurization control system uses a networked online monitoring and control technology to provide precise and efficient control of the pasteurization process. It enables real-time monitoring, data logging, and remote access for optimal process control, ensuring product safety, compliance with regulations, and efficient operation.
