Abstract: Provided is a kneading and granulating apparatus capable of adjusting the hardness of granules to be obtained with simple structure. The kneading and granulating apparatus includes a kneading section and a granulating section. The kneading section includes a first casing and two kneading shaft members. A plate-shaped first screen having a large number of holes formed therein is provided on a distal end portion of the first casing so as to close an opening portion of the first casing on the distal end side. A spacer is provided between the distal end portion of the first casing and the first screen, thereby being capable of changing a separation distance between a distal end portion of a screw portion of the kneading shaft member and the first screen.

Abstract: A fluidized bed apparatus includes a fluidizing container, a porous plate, a lower spray nozzle, a bag filter, an upper spray nozzle, a backwash nozzle, and a backwash nozzle elevator. The fluidizing container is formed in an inverted truncated conical cylindrical shape. The porous plate is provided so as to block a lower opening of the fluidizing container. The lower spray nozzle jets out air into the fluidizing container via the porous plate. The bag filter is provided at an upper opening of the fluidizing container. The upper spray nozzle sprays spray liquid downward. The backwash nozzle sweeps away powder particulates adhered to the bag filter by jetting out air from the outside of the bag filter toward the inside and is moved up and down by the backwash nozzle elevator. The fluidizing container may be vibrated by a vibrator.
