About this project
After touring several smaller vegetable producers across Iowa, the Fruit and Vegetable Working Group, a community of practice within the Iowa Value Chain Partnerships, identified a need to publish a low-cost system design for washing vegetables on the farm.
This paper presents two system designs for washing vegetables. The first system is based on the basic design of the vegetable wash station at One Step at a Time Gardens, located near Kanawha, Iowa. This system is designed to provide a simple and effective method of hand washing fresh vegetables using materials commonly available from a large hardware/building material retail outlet at a modest cost.
For the first wash station design you will find:
All drawings are presented in the Adobe PDF file format for ease of use.
The second system expands the first system to allow higher throughputs of vegetables. Commercially available vegetable washing and handling equipment are identified in the layout. This system also incorporates a cement floor and commercially available hoophouse covering for an extended season of operation. The addition of heating to the structure would extend the season even further.
For the second wash station design you will find:
This system can be seen as a step between the simple, covered but open-air system in the first design and a fully-enclosed, food-handling building for post-harvest processing of fresh vegetables (not included in this project).
Approximate costs to construct both systems are shown in the conclusion section, plus a presentation of each system’s pros and cons. Photographs of the first wash station are from One Step at a Time Gardens.
About One Step at a Time Gardens
Owned by Tim Landgraf and Jan Libbey, this farm is in its 16th year of producing vegetables, herbs, raspberries and pastured poultry. The farm’s primary markets are a Community Supported Agriculture (CSA) operation, area farmer’s markets, direct-to-consumer marketing and some targeted wholesale accounts. The farm is located near Kanawha in north central Iowa. With roughly 8 acres in vegetable production, the farm harvests fresh vegetable produce 5-6 days each week during the summer and fall.
