ABSTRACT:
An automatic animal feeder has a motor driven auger for supplying milk powder from a storage hopper to a mixing vessel. The mixing vessel has outlets for the continuous supply of liquid feed mixture to animal feeding locations. An electrical pump supplies water from a storage tank in the feeder to the mixing vessel. The auger and the pump are connected to an electrical control unit for delivering powder and water to the mixing vesel simultaneously in batches, the batches being automatically timed to provide a required powder to liquid ratio according to the setting of concentration selector switches on the front panel of the feeder. The batches of powder and water are supplied to the mixing vessel together in pairs when the liquid feed mixture is below a level determined by a sensor in the mixing vesel. Calibration of the powder supply is carried out by weighing a sample batch dispensed during a fixed calibration period and setting the measured weight on a calibration dial on the front panel. A heater is provided in the storage tank for heating the water prior to supplying it to the mixing vessel. If the temperature of the water is outside a predetermined range, the supply of both water and powder is disabled.
