Abstract: A feed device for a linear airflow separator that eliminates the use of a winnower in the separation of tobacco products. The feed device includes an adjustable angle baffle deflector in combination with an air knife. The air-fed adjustable angle baffle deflector feeds with non-product contact and as a result does not lead to mechanical degradation of the treated material. The air knife is fed with air from a high pressure blower having a variable frequency drive. The feed device treats the product with air only, thereby eliminating mechanical contact with the product and resulting in higher separation yields and higher operating efficiency than conventional recirculating pneumatic separators.
