Abstract: A system to automate the separation of agricultural products. The system includes an enclosure, sealed with permeable mesh to permit airflow and walled with non-porous material to prevent agricultural material from escaping the enclosure while allowing for flow to pass freely. This system is capable of separating material without mechanical interaction, such as with grippers or end effectors, and relies on air flow through the enclosure to create separation between the desired and undesired material using ballistic coefficient as a fundamental differentiator between constituent material of the agricultural products. This is accomplished with a variable speed fan which blows air through the enclosure, lifting and separating material based on the ballistic coefficient of that material and the flow settings. Dividers are used to separate and capture the products for retrieval at the conclusion of operation.
