The invention relates to improvements in the technical field of feeding solid materials to mixing devices. For this purpose, the solid-material feeding device, inter alia, is proposed. The solid-material feeding device comprises the slide, which can be moved between a first end position and a second end position through a conveying connection, which is arranged between a funnel and a solid-material outlet of the solid-material feeding device. By means of the slide, adhesions within the conveying connection can be loosened without having to remove the conveying connection.

A method of cleaning a food processor includes: (a) providing a food processor a base that includes a rotary power driver having a rotatable shaft; a bowl mounted on the base; and a food processing blade attached to the shaft within the bowl; (b) inserting a cleaning accessory into the bowl above the food processing blade; (c) introducing cleaning fluid into the bowl; and (d) rotating the food processing blade with the rotatable shaft to agitate the cleaning fluid.
