technical information

The Pedrotti Master Drier is constructed with a heavy duty chassis fitted with stabilising screw jacks and incorporating level bubbles. The drying chamber is fabricated from “Inox” perforated stainless steel and is framed for strength. Internal rotating agitators ensure continual grain recirculation giving facility for fast unloading. The centre auger is driven by short belts incorporating a gearbox giving a more positive drive.

On all RS models the top auger is raised and lowered by a geared winch unit which engages with the centre auger drive and is automatically securely fastened in one operation. The same principle applies to the top screen.

AIR Circulation

The centrifugal fan is quiet in operation and gives maximum possible air circulation throughout the drying chamber. The fan disengagement is very simple. A fan cover is provided on tractor drive models and an on/off switch for electric drive machines, this gives total control of air movement, especially during the loading/unloading process.

Heat requirements

The burner system incorporates a fail safe control system with photo cell cut off. Oil fired burners have a twin or triple jet oscillating principle controlled by independent solenoids with the possibility to interchange jets to meet any heat requirement. These dual fuel burners can be operated with diesel or kerosene and are economical, estimated at 5 litres per ton, giving 5% moisture extraction.
