An Evaporative Cooler for Vegetable Crops
Some vegetable crops are harvested with pulp temperatures too high and under humidity conditions too low for maximum shelf life. Present facilities for cooling produce and providing proper humidity usually consist of a system for rapid cooling as the commodity arrives from the field and a cold room for subsequent storage. Both are expensive to install, and the mechanical refrigeration system for the cooler requires large amounts of energy. The goal of this project was to develop a simple, low-cost, energy-efficient alternative that would be applicable to both large-scale and small-scale operations.
