Abstract:
1. A single pass material processing apparatus comprising: a. a cylindrical housing having an interior side wall and an inlet end having at least one of an air inlet and a material inlet, said air inlet admitting forced air at an elevated temperature into said cylindrical housing, said cylindrical housing further having a material outlet and defining adjacent processing sections including a first processing section and a second processing section, said second processing section being longitudinally offset from said first processing section along the length of said cylindrical housing; b. a dryer generating air at an elevated temperature, said dryer being in air flow communication with said air inlet; c. a shaft centrally located in said cylindrical housing said shaft comprising at least one agitator disk assembly, said at least one agitator disk assembly having at least one scraper blade; d. a plurality of beater blades on said shaft; e. at least one retention screen defining a plurality of openings therethrough, the at least one retention screen surrounding the shaft and separating adjacent processing sections; and f. at least two grinding members, said at least two grinding members including a first grinding member and a second grinding member, said first grinding member comprising a first contact surface comprising at least one mesh or screen element, and said second grinding member comprising a second contact surface comprising at least one mesh or screen element different from said at least one mesh or screen element of said first contact surface, said first and second grinding members being positioned proximate to said interior side wall, wherein said first grinding member is disposed in said first processing section and said second grinding member is disposed in said second processing section; wherein the at least one scraper blade and the beater blades are each positioned to rotate with the shaft and further wherein rotation of at least one of the at least one scraper blade and the beater blades is constructed and arranged to strike the material and to cause the material to strike the said grinding members, reducing said material in size.
