RTC Vertical cooler

The hot pellet is fed into the cooler box through the rotating feeder, the cold air enters the box through the extraction unit grid and cools the pellet.

The flow of cooling air that is created from the bottom up is given by the action of a fan connected to the suction hood. The cooler case is equipped with two level probes.
The minimum level indicator keeps the pellet layer in the container at a constant level. The indicator is adjustable in height for an excursion that varies depending on the machine model and the type of product to be cooled. When the indicator is covered by the pellets, the mobile grid controlled by the gear motor starts. The maximum level indicator mounted in the upper part of the case is used to stop the flow of the product into the container in the event of a fault or incorrect adjustment of the adjustable grid, preventing overfilling.

To divide the pellet load more evenly across the cooler area, a pyramid-shaped distributor of different sizes is mounted under the rotary feeder discharge depending on the model.
