Stainless body and discharge system

VPCG and VPCF series yemmak counterflow cooler is used for cooling the feed that is out from pellet mill in pellet form which is hot, to ambient temperature.

It works according to steady air form principle. Air in the external environment contacts the feed in the cooler; while the temperature of the feed drops, warm air is removed from the environment through air aspiration system.Discharge system which is on the cooler, removes cooled feed. Drainage system can be chosen with grid or hydraulic valve depending on the preferred product. While flap system is used especially in products with difficult fluidity, grid system is preferred for products with easy fluidity. While it is driven by a hydraulic piston in the flap system, it is driven by an electric motor in the grating system, while the pneumatic piston is used for buffering. Discharge system is adjustable and works according to the capacity.

Homogeneous cooling.
At the counterflow cooler outlet, the feed temperature is reduced to 5 ° above the indoor ambient temperature. The waiting time of the pellet in the machine can be controlled by the adjusted level sensors on the body. Thanks to the temperature sensors at the counterflow cooler outlet, the pellet temperature can be seen at the machine outlet.

Thanks to the distributor system in the counterflow cooler inlet, a homogeneous distribution and product height is provided inside the machine. In this way, the product is provided to cool equally at every point.

The temperature is controlled with the levels on the body. The feed dust in the warm air that moves to the aspiration system, are sent back to the system with the cyclone. After cooling, pellet feed durability. This way, dust output while packaging is prevented. Also, it gets optimum humidity and this way, pellet quality is extended. There are single or double deck models available for intended use.

Yemmak produces counterflow cooler models that allow pellets to be cooled with capacities between 5 - 40 tons / h. Single and double layered models are available according to the designed process.

Counterflow cooler models with a width and depth of 1400x1400 mm to 2800x3800 mm can cool the temperature of the product to be cooled up to 5 ° C above the atmospheric temperature.

The product in the counterflow cooler is exposed to atmospheric air at a speed of 1 m / sec for 12-13 minutes and the cooling process is performed.

Choosing the right model is important for efficient cooling of pelleted products with diameters between 1.8 mm and 16 mm. As the diameter of the pellet increases, it becomes difficult to cool the inside of the pellets, so the cooling model needed grows.

"The most efficient operating conditions are provided by choosing the right model with Yemmak engineering and experience."
