A continuously spray type cooling tunnel is a specialized piece of equipment used in industrial processes to rapidly cool products or materials. It is commonly used in the food and beverage industry to cool down products such as baked goods, confectionery, and beverages.

The cooling tunnel consists of a long conveyor belt that runs through a tunnel-like enclosure. The product or material to be cooled is placed on the conveyor belt, which moves through the tunnel at a controlled speed. As the product moves through the tunnel, it is continuously sprayed with cool water or a refrigerant fluid.

The spray nozzles are strategically placed along the length of the tunnel to ensure even and efficient cooling. The cool liquid absorbs heat from the product, causing it to cool down rapidly. The excess heat is carried away by the liquid, which is recirculated and cooled using a refrigeration system.

The cooling tunnel can be equipped with adjustable settings for conveyor speed, spray intensity, and temperature control, allowing for precise cooling conditions tailored to the specific product requirements. The length and width of the tunnel can also be customized to accommodate different production capacities and product sizes.

Overall, a continuously spray type cooling tunnel provides a fast and efficient cooling solution, ensuring that products are cooled down quickly to maintain their quality and prolong their shelf life.

Application

Tunnel spraying cooler adopts recycling warm water to perform pre-cooling and use spraying cold water to cool down, which takes 3 procedures; the temperature and holding time can be regulated and auto controlled; This type cooler is widely used to cool the bottle, can packed type acidic milk, juice, beverage, beer, and flavor etc.
