The postharvest handling and storage of dry beans and other pulses is an important aspect in providing high quality products. Quality of beans during storage is susceptible to numerous of problems such as insects, mold, rodents, which warrant employing improved postharvest management throughout supply chain channels to preserve food safety and quality. It must be emphasized that dry beans require careful handling and monitoring to ensure stability throughout their postharvest life span. It must be clearly understood that it is important to move dry beans from field production to the final processing facilities in a controlled and sequential manner. Typical unit operations associated with the handling and cleaning of dry beans prior to receipt at the canning facility are shown in ssss1.

Dry bean planting varying according to regional conditions. In Michigan, planting takes place between late‐May and early‐July, with about 75% planted in the first two weeks of June. Dry beans that do get planted in cold, wet soils typically struggle throughout the growing season fending off root diseases. In order to improve conditions at harvest time, growers “roll” bean fields between planting and emergence with a wide roller to flatten the field surface. This process presses any stones and rocks below the soil surface and flattens the surface, which enhances cutter bar efficiency and results in significant reduction stones, dirt balls and debris in the harvested beans (J. Cramer 2020, personal communication).
