UBC Farm – Flame Weeder

T22 Flame Weeder

Abstract

The organic market share in the food industry has grown steadily to reach an irreplaceable position with good reason. Awareness around genetically modified organisms (GMO’s) and chemical pesticides have raised serious concerns in the minds of modern consumers. At UBC Farm the goal is to research and grow organic and sustainable produce with the local and global market in mind. Instead of using the commercially available chemical pesticides, an alternative organic solution was desired and commissioned for completion by a student team at UBC.

The primary objective during the 2015 Mechanical Engineering Capstone project for team 22 was to create a flame weeder prototype that could be used at a regular walking pace and eliminating weeds at a high consistency. Our flame weeder consists of a burner assembly and an ergonomic frame. The burner system emits jets that are resilient even in high crosswind conditions. The frame is custom designed to fit the parameters as requested by UBC Farm. The frame and burner can be adjusted into several stages to optimize transportation, flaming, or storage.
