UVM Extension Ag Engineering

UVM Extension’s own television program Across The Fence did a segment on a project we’ve been working on related to greens spinners. You can watch the video clip here explaining why small farms are making use of washing machines as greens spinners and what we are doing to help make them more feasible.

Washing Machine Greens Spinners: Shopping Advice

This blog post is for those using or considering a converted washing machine as greens spinner. 

Background

For background information on several different types of greens spinners and general thoughts on using washing machine conversions see this blog post

Shopping Tips

What to look for when shopping for a washing machine for a greens spinner? The details are in the drum. Minimize seams, nooks and crannies for an easy to clean surface.

There are a few things to consider when shopping for a washing machine to convert into a greens spinner. Like most things, it comes down to:

  1. How much you want to spend, and
  2. What features are important to you. Continue reading “Washing Machine Greens Spinners: Shopping Advice”

Greens Washline from China

With innovative tools becoming more available for salad greens production from field prep through harvest, mixed greens are becoming more attractive for farmers. Postharvest handling and wash/pack still causes a bottleneck for many farms. Today we share some knowledge on a piece of equipment recently adopted at Jericho Settlers Farm in Jericho, VT.

This Greens Washline is made by China Joy Equipment. They call it an “Air Bubble Washing Machine.” This has been an affordable piece of equipment to allow their farm to scale up greens production for $13,900. Mark Fasching from Jericho Settlers Farm was gracious enough to share some of his experiences sourcing this machine from the other side of the world.

Ventilation in Greenhouses and High Tunnels

I had the pleasure of facilitating a workshop at the 2019 NOFA-MA Summer Conference about Ventilation in Greenhouses and High Tunnels. It provided an opportunity to collect information from various sources, ground truth observations with growers, and to revisit some fundamentals. The big takeaway, for me, is that there are many, many ways to ventilate a protected culture environment and opportunities for improvement abound.  I hope this review provides a framework for troubleshooting some issues that may be common in the field.

This organic vegetable farm on the Connecticut River provides over 200 CSA members, farmers market, restaurant, and wholesale customers with local, healthy food. Over 100 different varieties of crops are grown on the 38 acres that make up the farm. Continue reading “Wheels Keep Things Rolling at Root 5 Farm”

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 test demonstrated the feasibility and benefit of simple forced air cooling systems to smaller scale farms.

Hygienic and Sanitary Design for Produce Farms

Hygienic design intentionally creates or improves spaces and equipment so they can be cleaned and sanitized as appropriate.

This joint illustrates how intermittent welds lead to a gap, or sandwich joint that can lead to harborage. A continuous weld that is then ground smooth would lead to a seal and be easier to clean, sanitize, and dry completely.

This post, associated PDF guide and checklist (PDF and Excel) are tools we developed to help apply hygienic and sanitary design practice on produce farms. These tools cover the five key principles of hygienic design for produce farms:

  1. Visible and Reachable Surfaces
  2. Smooth and Cleanable Surfaces
  3. No Collection Points
  4. Compatible Materials
  5. Preventing Contamination
