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 […]
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.

Farms that need to cool smaller volumes of produce can also benefit from forced air cooling. Whether cooling stacked pallets, pallet bins or individual cartons, the same principals apply. A smaller pallet cooler was noted on […]

Framing: 2”x12” lumber to make a 43” wide x 74” tall x 11-1/4” deep plenum for suction air distribution. Plenum Panel: 3/8” CDX Plywood with an 11-1/4” circle cut out for the blower suction inlet. Position […]
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 […]
This presentation discusses several different options for record keeping and tracking of produce safety documents and farm logs on an online interface. This was recorded at the Great Lakes Expo in Grand Rapids Michigan December 2017 and given by Chris Callahan UVM Extension, Ag Engineering.
This video is an episode from Across the Fence! It holds an interview with Judy Simpson as well as a description of the product.

UVM Extension and others supported the recent installation of a 341,200 BTU/hr (output) multi-fuel biomass boiler at the Vermont Farmers Food Center (VFFC) in Rutland, VT. The boiler heats the Farmer’s Hall building with the capability to use several alternative fuels to displace propane. The boiler was fueled primarily on wood pellets but was also […]
Recent testing at the Meach Cove Trust has demonstrated strong economic and technical feasibility of grass-based biomass combustion fuels. The use of solid, densified, cellulosic biomass fuels has been well demonstrated with wood pellets in residential and light commercial systems and wood chips in larger, often centralized systems. The Grass Energy Partnership of the Vermont […]
This project demonstrated the use of biomass heating for greenhouse vegetable production at sites across Vermont. From 2008 through 2015, 25 growers received cost-share funds for greenhouse biomass heating systems.
