The felt dryer is a drying machine for potatoes and other round shaped root crops. The machine is equipped with rollers covered with felt, which will absorb the adherent water from the product. This water is squeezed out of the felt by means of adjustable pressure rollers which are positioned under the felt covered rollers. The pressure rollers are equipped with separate springs, which assure uniform and effective drying. A drip tray is assembled under the machine to collect all water from the product. This drip tray is equipped with a drain which can be connected to the central water discharge system, which assures clean work in the processing area. The machine is standard equipped with a variable frequency drive to be able to adjust the speed of the rollers stepless. An integrated bypass conveyor can be offered as an option, to bypass the felt dryer when the machine is positioned in a line with other machines.
