ABSTRACT:
A mixing system is provided for mixing and dispensing measured volumes of kneaded material. The system includes an adjustable frame, top and side feeder assemblies, a cutter assembly. The top feeder assembly is secured to the frame and maintains a supply of raw kneadable material and minor ingredients to the side feeder assembly. The side feeder assembly includes an input housing, receiving raw material from the top feeder assembly and a preblender housing in communication with the input housing. A pair of oppositely rotating helical screws are disposed within the input and preblender housings for transporting the kneadable material to the kneader cylinder. The input and preblender housings are detachably connected to one another and slidably mounted on the frame, for selective movement between operating and cleaning positions. The preblender housing is also rotatably mounted on the frame, which further facilitates cleaning the unit. The cutter assembly includes a blade assembly which is selectively activated based on the volume of material entering a cutter housing from the kneader cylinder. A knife blade rotates in a circular motion so as to periodically sever a desired volume of kneaded material. The blade rotates away from the stream of material to a safety position between cuts. The system incorporates several safety features which disengage an electric motor used to drive the blade assembly upon detection of various conditions.
