PETKUS DU Continuous Flow DryerPETKUS Continuous Flow Dryers are based on roof column design for drying processes of various types of cereals:
- Grain, maize, oil seed,
- Feed grain,
The PETKUS Dryer is designed in completely modular construction to ensure a wide range of models and capacities (from 5 to 60 t/h, based on wheat) by the different assembly possibilities of the main components. In total 3 types of dryers are available:
Type DU 1500 / DU 2500 / DU 4000 (see the Datasheet).
The working principle of the dryer type DU (Direkt-Umluft) is based on direct heating by gas or oil burner and recirculation of the air. Aspiration systems or filter systems are not necessary.
Construction:The warm air production is carried out directly by the use of either an oil burner + burn heat chamber or with a gas flat burner and installed in the warm air column. The air stream velocity in the drying column can be adjusted and controlled due to the treated product by air aperture slides which are installed in the exhaust air column.
In the drying column are installed conical air channels cascades.
These air channels are closed on one side and installed mutually and can be used for in-suction and out-suction of air.
Based on the mutually installation of the air channels the product in the drying column will be even treated with warm air. Axial fans in the dryer roof are working in suction process and producing the air stream in the product column. Behind the axial fan an air louver is closing the air aperture during the discharge process of the dryed product, this system avoids that the dust is flowing into the environmental during when the product is being discharged.
