Abstract
A feeding screw machine serves for feeding a processing screw machine. The feeding screw machine comprises a housing with at least one housing bore formed therein. An associated screw conveyor shaft is rotatably disposed in the at least one housing bore to convey material in a conveying direction from a supply opening to a feeding opening. An emptying opening is formed in the housing. The emptying opening enables an easy, fast and reliable emptying and cleaning of the feeding screw machine independently of the processing screw machine.
