Abstract: The food material to be processed is alternately transferred from two sources to an elongated treating chamber. The apparatus for carrying out the method includes rotary valve means employing two pocket areas, each pocket area including a plurality of pockets with each pair of diametrically located pockets having an interconnecting passage. The pockets of one area are angularly displaced or out-of-phase with the pockets of the other area. Owing to the out-of-phase relationship, the food material to be processed is alternately received by one pocket of one area, then by the next pocket of the other area and so on through each revolution of the valve means in which the pockets are contained, the material being discharged in the same out-of-phase relationship through the interconnecting passages and diametrically disposed pockets into the inlet of a pressurized elongated treating chamber.

Abstract: A method is provided for preparing a breading material suitable for use in coating various meat and vegetable products. A mixture including flour, yeast, whey together with various other materials is fed into an elongated treating chamber under pressure. The chamber has an inlet at one end and an outlet at the other end. A flow of hot gaseous fluid from the direction of the inlet propels the mixture through the elongated chamber and out of the outlet.

Abstract: Apparatus for treating particulate heat and pressure reactive food material. The food material is fed into an elongated treating chamber which is under pressure. The chamber has an inlet at one end and an outlet at the other end. The food material is fed into a continuous flow of gaseous fluid from the direction of the inlet and propelled through the elongated chamber and out of the outlet.
