Feed device for linear airflow separator

摘要

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.

主权项

1. A feed device for a linear airflow separator comprising:
a blower; an air-fed adjustable angle baffle deflector including an air knife, a deflector baffle including a ramp portion with a planar top surface, and a pivot at an upstream end of said ramp portion; said air knife positioned at a distance above and at an angle with respect to said ramp portion to impinge air on said planar top surface of said adjustable angle baffle deflector; said air-fed adjustable angle baffle deflector is rotatable around said pivot; a means for delivering a particulate stream onto said planar top surface of said ramp portion; and said air knife and said baffle deflector are maintained in a fixed relationship to one another and rotate as a unit to adjust the trajectory of the particulate stream into the linear airflow separator.
