Automatic extrusion animal feeder

Abstract

A device for feeding animals moist and semi-moist food at selected times including a tubular casing having a convergent outlet and an open inlet. An extrusion assembly including a piston longitudinally movable in the tubular casing is provided and sized to be received in the tubular casing to travel a portion of the length thereof. A drive arrangement is provided to extend the piston into the tubular casing to extrude food through the outlet at selected intervals and for removing the piston from the tubular casing for refilling the tubular casing. Interval operational timing devices are provided for selecting the frequency and duration of the operation of the feeding cycles and can be operated by programmable time control devices. Additionally, solid state heating/cooling devices can be provided so that the food extruded from the tubular casing can be heated or cooled as desired for emission from the feeder.
