Countercurrent cooler

The counter-current cooling system is designed to cool the granules after the granulation process to a temperature of ± 5°C above ambient temperature. This is necessary to ensure good strength of the granules, their fluidity, resistance to destruction and minimization of chemical and biochemical reactions.

Characteristics and features

• Equipped with a stainless steel rotary valve with a motor console, clutch and gear motor;
• The lid and sides are made of stainless steel;
• An inspection hatch for monitoring the filling level, as well as two adjustable level indicators;
• All necessary connections for air flow to the rotary valve and exhaust fan are on the roof of the cooler;
• A pellet discharge device consisting of two fixed and adjustable and one movable section;
• Hopper-funnel for dumping pellets with pipe connectors;
• Steel support structure next to the exit;
• The system of discharge of the full surface of the cooler, driven by an air piston with a solenoid control valve;
• Inlet valve for continuous product flow and air blocking;
• Ultrasonic sensor for constant monitoring of the layer thickness to ensure and/or control the retention time in the cooler;
• Automatic control of the air flow by an electrically operated valve to adjust the air velocity in the cooler;
• Frequency controller for adjusting the speed of the unloading mechanism;
• Octagonal design for optimal cooler filling.

Advantages

High efficiency:

• Compact, takes up little space;
• Low power consumption due to low air volume;
• Minimum maintenance downtime;
• Continuous discharge of pellets for optimal cooling process;
• Minimal damage to the product due to the unloading mechanism;
• Optimal moisture content of granules;
• Reliable design of the unloading mechanism.
