Water-bath Cooling Tunnel for Hot Filled Sauce Pouches and Food Products
A Water-bath cooling tunnel is a cooling machine used to gradually reduce the temperature of hot-filled bottles, cans, and jars after filling or pasteurization. It sprays circulating water over the containers at controlled temperatures, providing uniform cooling while helping prevent thermal shock, bottle deformation, and product quality loss. Water-bath cooling tunnels are commonly used in hot-fill juice, tea, fruit beverage, sauce, and other beverage production lines.

Description

The Water-bath cooling tunnel is designed for controlled cooling of hot-filled sauce pouches, sauce sachets, bottles, cans, and other heat-processed packages. After hot filling or pasteurization, the products pass through the cooling tunnel on a continuous conveyor while circulating water is sprayed over the packages to gradually reduce their temperature.
For sauce pouch cooling, the water-bath cooling tunnel provides gentle and uniform cooling to help protect the pouch shape, packaging integrity, and product quality. The cooling process can be divided into multiple temperature zones, allowing the product temperature to decrease gradually and reducing the risk of thermal shock. The circulating cooling water is collected and reused to improve water efficiency.
The tunnel length, cooling zones, conveyor speed, water temperature, and spray system can be customized according to the sauce type, pouch size, filling temperature, production capacity, and required outlet temperature. It is suitable for hot-filled tomato sauce, chili sauce, ketchup, cooking sauce, fruit sauce, seasoning sauce, and other packaged food products.
