ABSTRACT:
An improved feed dispenser is programmable to allow for a desired feeding schedule. When a feeding interval begins, a dispersion wheel begins operating. A separate spinner plate is used to block feed from the dispersion wheel, and begins operating to allow feed to the dispersion wheel only after a delay of several seconds after the dispersion wheel begins operation. In addition, the dispersion wheel is operated for another period of several seconds after the spinner plate ceases operation in order to clear the mechanism and prevent blockage.
