New Mexico State University (NMSU) is involved in the mechanization of the chile industry in the region. One initiative of major importance to processors is the design a high capacity method of removing the stems from chile peppers. Stems are considered a defect due to the lowering of the quality of chile products, and the stems also present a choking hazard. NMSU engineers have developed a series of de-stemming prototype models ranging from straightforward mechanical solutions to more complex electro-mechanical solutions. Refinement of the performance of each bench model is critical to the comparison of each concept. The goal of testing and modifying the prototypes is to achieve a design that will allow de-stemming production rates of 10,000 pounds of chile per hour.
