Continuously spraying type pasteurization and cooling tunnels are used in the food and beverage industry to effectively pasteurize and cool products. These tunnels are designed to provide consistent and efficient heat treatment to ensure product safety and quality.

The process begins with the product being transported through a conveyor belt system into the tunnel. As the product moves through the tunnel, it is continuously sprayed with hot water or steam to achieve the desired pasteurization temperature. The spraying system ensures even distribution of heat throughout the product, eliminating any potential bacterial contamination.

After reaching the required pasteurization temperature, the product is then cooled down using a similar spraying system with cold water. This rapid cooling process helps to preserve the quality and freshness of the product while preventing any bacterial growth.

The continuously spraying type pasteurization and cooling tunnel offers several advantages. Firstly, it provides a continuous and automated process, allowing for high production rates and efficiency. The even and thorough heat treatment ensures that all areas of the product are properly pasteurized, reducing the risk of pathogens and extending shelf life.

Additionally, these tunnels can be customized to suit different product types and sizes, making them versatile for various applications. They also feature precise temperature control and monitoring systems, ensuring the product's integrity and consistency.

In conclusion, continuously spraying type pasteurization and cooling tunnels are an essential component in the food and beverage industry. They provide an effective and efficient method for pasteurizing and cooling products, ensuring their safety and quality while maintaining high production rates.

Application
Spraying Sterilizing & Cooling Tunnel is designed specially for milk, juice, drink, beer, food and drug after packaging, which can help to postpone the storage period by sterilizing and cooling. It is recommended as a second pasteurization in the piplining. It can be prepared in different process even with high auto-controlling according to the specific request from customer like heating, sterilizing, warm-keeping and cooling.

This equipment can provide the working performance which is more equal, compensate and rapid than traditional water sterilization which can help to improve the efficiency and decrease the manufacturing cost and improve market competition for the customers. The main character of this equipment is that the net can be used for a long time, and won’t bring a large distortion in high temperature, which is used the imported spray mouth to homogenize the flow and temperature. The temperature can be chosen as the PLC or PID controlling.

This machine can be customized to equip the Full automatic control system, and PLC or PID control for sterilizing.
