Abstract
There is disclosed a mobile apparatus for mixing and dispensing mixtures from an ingredients container including a hopper with a channel-shaped floor portion containing a screw auger. A cover over the screw auger may be raised so that a gap between the cover and the hopper walls allows metered amounts of ingredients to be conveyed by the screw auger to a separate mixer and a dispenser. The mixer and dispenser can be in the form of a tapering ribbon-blade mixer located in a frusto conical hollow body pivotally, slidably and extendably mounted at the rear of a transport vehicle. The mixer and dispenser can be pivotally mounted to a bracket mounted on rails to move slidably across the width of the transport vehicle.
