<p>PROBLEM TO BE SOLVED: To provide an agitation-crushing apparatus which can crush garbage effectively in a short time without forming cakes of the garbage even when the garbage contains fats and oils, cooked rice, and water mainly. SOLUTION: In the inside of a treatment tank 1, an agitation screw 3 is installed rotatably to make its upper part be inserted into a cylindrical agitation cylinder 2 having holes 23 for crushing. In the screw 3, a part inserted into the cylinder 2 forms a feed part 15, and a part protruding from the lower end of the cylinder forms an agitation-crushing introduction part 16 having a rotational diameter larger than the outside diameter of the cylinder. Since the introduction part 16 is spiral, its peripheral surface has an agitation effect, and since notches 20 for crushing are formed in the peripheral surface, objects can be crushed effectively.</p> |
