Comil dryers incorporate innovation and modern technologies, utilizing wood for drying the grain such as soy, wheat, corn, rice, barley, without relying on electricity or natural gas. Comil dryers come in variety of sizes and capacities, ranging from 20 to 150 t/h and humidity removal of 18% to 13%. Comil dryers provide additional thermal energy saving, due to the reutilization of the heat from the cooling zone. Major power saving are achieved, due to reuse of the air and also the high performance of the axial fans, as well as, greater drying homogeneity due to more uniform static pressure.
Designed for constant, uniform grain-flow to the dryer during operation. Equipped with a level sensor, connected to the loading mechanism. Prevents escape of hot air in the upper part of the drying tower. Electric motors help provide a uniform distribution of the grain for increased efficiency in drying capacity.
Made with reflector panels with built-in flow, through which grain is heated via the hot air oven. This system can operate in both heating/cooling and full heat mode.
Unloading of grain utilizes inner valve operated by motors for an equal rate of unloading. The speed of the valves is controlled via the control panel.
The control system is designed to select the modes for multiple grain drying operations. With open ventilation hatches dryer is operated in 2/3 heating mode and 1/3 cooling. For long-term operation - dividers and dampers are made of galvanized steel. This system allows you to mix the hot air from the furnace and cool air for smooth operation.
Dryers are equipped with internal stairs and platforms for access to the drying tower, bunkers and internal floors. Optionally, the ladder may be provided for external access to the hopper.
A fan mounted at the front of the dryer maintains a uniform velocity of the air passing through the drying tower, providing a uniform flow of heat throughout the grain. A dust particle collector meets the standard for the emission into the environment at 75mg/m³.
Built from standard bricks and metal on the outside and heat-resistant thermal bricks on the inside of the combustion chamber, we create an easy to implement and low cost furnace that operates on 100% wood burning fuel. Equipped with iron railings and doors for a long lifetime with an effective system of air tunnels for the passage of hot air and elimination of sparks inside the dryer.
To control the inner air temperature, 3 sensor are installed. A first sensor located at the inlet of the dryer, the second at the top of the dryer and the third at the outlet of the dryer. Grain loading speed is manually adjusted depending on the culture and the temperature.
The heated air in the cooling process is mixed with the hot air from the furnace. This saves energy and 50% to 30% of the thermal energy. The full heating system also utilizes reusable hot air for increased performance.
