PLC Control Fruit Juice Pasteurization Sterilizer Machine

Sterilization is a crucial step in the fruit juice production process. After being squeezed, concentrated, or blended, juice still contains a certain amount of microorganisms and enzymes. Without sterilization, the fruit juice can deteriorate, lose flavor, and shorten its shelf life. Therefore, juice production line are often equipped with efficient juice sterilizer machine to ensure juice quality and food safety.

Pasteurization is a low-temperature sterilization method commonly used in juice production. Its core principle involves heating the fruit juice to a temperature between 85°C and 95°C for a specific period (usually 15 to 30 seconds) to effectively kill pathogens and most spoilage microorganisms while preserving the juice’s nutrients and natural flavor. Compared to ultra-high temperature (UHT) sterilization, pasteurization operates at a lower temperature and reduces thermal damage, making it more suitable for juice processing and ensuring the juice’s taste, color, and aroma are maintained.

Fruit Juice Pasteurization Machine Features:

• Resistant to coking and long operating time: The juice sterilizer machine utilizes a scientific heating and heat exchange structure to prevent the formation of sediment or coke during the heating process, significantly extending continuous operation time, reducing the need for frequent machine downtime and cleaning, and improving production efficiency.
• PLC Control for Simple and Accurate Operation: The fruit juice pasteurization machine is intelligently controlled by a PLC controller, automatically adjusting and monitoring parameters such as sterilization temperature, holding time, and flow rate. Operators simply set these parameters in the system for a precise and stable sterilization process.
• Built-in CIP Cleaning System for Easy Cleaning: The juice sterilizer machine features a built-in automatic CIP cleaning interface, allowing seamless integration with the factory’s cleaning system. This efficient and thorough cleaning process not only saves labor and time, but also ensures hygienic production environments.

Juice Sterilizer Machine Applications:

Juice pasteurizer machines are widely used in the processing of various juice beverages, including:

1. Mango juice: Mango pulp is rich in fiber, so pasteurization eliminates microorganisms without damaging the flavor, extending shelf life.
2. Pineapple juice: Pineapple juice has a high acidity, so pasteurization effectively inhibits the growth of yeast and mold, improving product stability.
3. Orange juice: Orange juice is high in vitamin C, so pasteurization eliminates bacteria while preserving nutrients and maintaining a refreshing taste.
4. Other juice products, such as apple juice, grape juice, and blended juices, can also be processed using pasteurizers.

A juice sterilizer machine is more than just a sterilizing device; it’s the core component of a juice production line. It performs the following functions:

• Ensures food safety—Effectively inactivates pathogens, ensuring the juice meets food safety standards.
• Extends shelf life—By sterilizing, it inhibits microbial growth, ensuring the juice remains stable at room temperature or under refrigerated conditions.
• Preserves juice flavor—Low-temperature pasteurization minimizes the loss of nutrients and aroma.
