ABSTRACT:
A vacuum cooler for produce and the like comprising a vacuum tube forming a vacuum chamber into which produce is placed. A vacuum pump lowers the atmospheric pressure while cold water is gently sprayed onto the produce. Water vapor from the produce is condensed, and directed to a sump in the chamber without permitting such condensed water to impinge on the produce. The cooler includes a venting system that admits outside air into the vacuum chamber, gradually returning the chamber to atmospheric pressure, and permitting removal of produce from the chamber.
