Forced Air Cooling: Field Trial Results

Last summer we performed a series of precooling trials using small-scale forced air coolers to cool eggplant, watermelon, strawberries, blueberries, zucchini, and roasting peppers. The forced air cooling was done in parallel with standard room cooling and was shown to result in cooling rates ranging from 1.2 to 2.2 times faster than room cooling. This […]

Postharvest Resource Survey

We are seeking input regarding a research and education project with the goal of consolidating postharvest information in a single set of resources. Our proposed project aims to consolidate existing knowledge, best practices, and new developments in postharvest equipment, infrastructure, and buildings into a web-based handbook, workshop curriculum / educational materials and recorded videos.

Forced Air Cooling On The Farm

A downloadable/printable pdf of this article is available here. Introduction The preservation of quality in fresh market and storage crops on small and medium-sized farms in the Northeast depends on the rapid reduction of pulp temperature and maintenance of relatively low temperatures to slow metabolic respiration. There is strong foundational work showing that rapidly reducing […]
