The Cooling Tunnel is a specialized industrial equipment designed to rapidly cool down items, such as bottles / jars which have been filled with hot liquid and which need to be cooled / frozen so as to cap / seal the container.

The Cooling Tunnel has Multi lane conveyors which helps maximize contact between the product and the cooling air.

For e.g. products like Petroleum Jelly, Balms, Jams, Shoe Polish, Kajal etc. are filled in hot state and require cooling and the top layer to solidify so as to make it convenient for closing / sealing.

Components

1. Input Conveyor: The cooling process begins with the introduction of items, typically bottles filled with a substance like petroleum jelly, onto the input conveyor.

2. Multilane (Zig-Zag) Conveyor: The bottles are then transferred onto a Multilane conveyor inside the cooling tunnel. This conveyor's design helps maximize contact between the bottles and the cooling air.

3. Cooling Blowers: The cooling tunnel features cooling blowers that generate controlled airflow. This airflow is directed towards the bottles, promoting heat exchange for cooling.

4. Chiller Unit: To maintain the air's temperature at the desired level, a chiller unit is integrated with the cooling tunnel. The chiller cools the air before it's blown onto the bottles, facilitating efficient cooling.

5. Multiple Passes: The Multilane (zig-zag) conveyor allows the bottles to pass through the cooling blowers multiple times. This multi-pass approach ensures thorough and even cooling of the items.

6. Temperature Control: The temperature of the cooling blowers and chiller unit is regulated to achieve the optimum cooling rate. This helps prevent product damage while ensuring almost solidification.

7. Output Conveyor: Once the bottles have undergone the cooling process, they are transported out of the cooling tunnel via the output conveyor.
