Abstract
Abstract Mixing and extruding apparatus for the preparation of a confection comprises front and rear bearing blocks in which two axles are journaled, mix extrude screws detachably secured to said axles and extending into a mixing chamber, and means for detachably clamping the mixing chamber to the front bearing block. The mixing chamber includes a barrel in which a recirculation plate is positioned to rotate the mix back into the screws for continuous mixing and extruding. A slidable gate can be moved to open an outlet aperture in the mixing chamber so that the mixture can be expelled from the chamber by the screws.
