Material List and Cost Calculator for Building a Wash Table and Aerator

Our model wash table was built from parts purchased entirely from a decently stocked hardware store. The list contains all the components we used to build the main table, the side modular tables, and the "dirty table". Also listed are the prices we paid to give you an idea of a building price. The real goal for these tables is to demonstrate that it doesn't require high priced equipment to get started in setting up an easily cleanable wash line set-up. The idea is to have something usable whether it is indoors or outside under canopies. The key is having the tables and equipment that can be easily cleaned and sanitized while being low-cost, easy to build, and totally functional.
There is a second page of the spreadsheet that includes the materials list and cost for building an aerator. The concept of the aerator is to pump air in a tank of water that can agitate leafy greens or heads of lettuce, escarole, etc. to quickly remove soil and debris as well as keeping any added sanitizer in the water to reach in around the produce. The Jacuzzi motor was found at a spa parts website. I ordered a 1 hp model. Very quickly we realized that this was too powerful for any tank or basin less than 50 gallons or greater and needs high sides. A 7/8 hp motor or something smaller would work fine. The motor purchased had a 2" diameter exhaust that fit easily to a 2" PVC pipe. Do not glue the PVC pieces in the bottom of the tank together totally. The unit will suck in soil and debris when you turn off the motor after use and will need cleaning after each day's use. Having the PVC pipes in the bottom of the tank fit snuggly with the inside perimeter will help in keeping the unit from floating when the motor is turned on. More holes drilled into the PVC would help reduce floating. Using an easily cleanable weighted object to hold down the pipes can also work. To see the aerator in action, go to our video and the last couple of minutes of the video is on the aerator.

Intro to Food Safety and GAPs Training
February 19, 2025
via Zoom,
This virtual workshop will serve two purposes:
- For produce farms just interested in learning about farm food safety, this program will introduce principles and best practices.
- For produce farms look for a GAPs (Good Agricultural Practices) training needed to meet buyer demands for audit/certification, this program will provide that as well.
