NIGHT PICKING OF FRUITS AND VEGETABLES TO REDUCE COOLING LOAD.

Summary

PICKING IN THE RELATIVELY COOL THERMAL SINK OF NIGHT AIR AND BLACK SKY FROM MIDNIGHT TO SUNRISE CAN ALLOW PRECOOLER INPUT TEMPERATURES NORMALLY 11K COOLER THAN FOR DAYTIME HARVEST. THE 40% REDUCTION IN COOLING LOAD AND THE 5 HOUR EARLIER DAILY START-UP OF COMPRESSORS CAN PROVIDE SUBSTANTIAL ENERGY SAVINGS AND TIME-OF-USE BENEFITS FOR PRECOOLER OPERATORS. MOBILE ILLUMINATION APPARATUS ATTACHED TO PICKER AIDS SUCH AS PLATFORMS, BELT LOADERS OR SPECIAL CARTS AND USING FLUORESCENT LAMPS POWERED BY ATTACHED PORTABLE GENERATORS HAVE BEEN HIGHLY SUCCESSFUL AND COST EFFECTIVE.
