<p>A closed food processing vat particularly for use as a cheese curd vat where at least one rotatable vertical shaft within the vat has a pivotally associated cutter frame stopped so the frame when the shaft is rotated in one direction is moved to a cutting position extending as a radius from the shaft with the cutting edge of the blades in the frame leading to a stirring position when the shaft is rotated in the opposite direction with the frame automatically moved as a reaction against the product in the vat to a position at an angle to the radius so that the projection of blades in the frame relative to the direction of rotation is increased to stir the product.</p> |
