Problem Statement

Loebach Brothers LLC is a company consisting of Dave and Joe Loebach. They hold design patents for the “Dorothy” projects. There are no stakeholders for this company. The group created a system that rapidly removes moisture from grain without using a heating element. The group redeveloped a previous prototype that is scaled to a full-size grain bin. The previous prototype was built without drawings and how it was manufactured was mostly through speculation and the client’s industry experience. However, the group does have a picture of how it was built. The client wanted this built for proof of concept on a large scale. The group was tasked to focus on building just the dehumidification unit, as the project scope constantly changed.
