  • Patent number: 4145820
    Abstract: A moisture remover for produce is preferably installed in an enclosure within which a produce support such as a foraminous conveyor is installed. A fan takes heated air from a heater and discharges the heated air upwardly through the conveyor and then through the produce itself. Air leaving the produce returns to the air heater for reheating and recirculation by the fan. Moisture from the produce rises and travels to a cooler within the enclosure and condenses on the cooler. There is no air circulation through the cooler. Moisture condensed on the cooler is drained from the cooler and preferably is discharged outside the enclosure and is not reevaporated into the recirculating heated air.
