ABSTRACT:
Improved apparatus and method are provided for the dispensing of particulate material from the gravitationally bottom discharge mouth of a hopper. In a presently preferred form, the particulate material moves downwardly first through a conically sided zone to a toroidally-configured aperture, and, after passage therethrough, moves downwardly through a cavity that preferably has a cross-sectionally circular perimeter. Centrally upstanding in the cavity is a body with preferably conically diverging sides over which the particulate material moves downwardly to a cover plate or deck which has a circumferentially extending discharge opening through which the particulate material is discharged. Most preferably, the body also extends upwardly through the aperture and through the conically sided zone. Particulate material downward movement and discharge is produced by shaking, preferably vibration, of the deck. A presently preferred particulate material is fish feed. The apparatus and method avoid particulate material bridging and hang-up and provide the capability for achieving uniform dispensing rates generally independently of the fill level of particulate material in the hopper.
