Abstract
1505946 Pneumatic separating AMF INC 9 Sept 1976 [28 May 1976] 37468/76 Heading B2H Threshed tobacco is separated into lighter and heavier fractions by introducing it into a chamber 30 containing two adjacent vortices VA and VB circulating in opposite directions and coacting to form a rising column of air which carries off the said lighter fraction through an outlet 38. The heavy fraction falls to the bottom of the chamber and is carried away by a stream of air flowing along a duct 39. The tobacco is introduced into the chamber through an inlet 31 and air is blown into the chamber through opposed inlets 34 and 35. Each inlet 34 and 35 comprises a plate 40 provided with rows of ports 41. A slidable plate 42 having openings 43 is provided for each row of ports 41 to control the flow of air therethrough. Adjustable vanes 44 in the chamber adjacent the plate 40 control the direction in which the air enters the chamber. Air may also be introduced to or withdrawn from the chamber 30 through a valve 26 to prevent interaction between the air flows and pressure in the chamber 30 and the air flow and pressure in the duct 39. The air removed through the outlet 38 is recirculated to the inlets 34 and 35 by a blower (15) after removal of the tobacco therefrom. A portion of the output of the blower (15) may be bled-off through a pipe (18) and a blower (20), Fig. 1 (not shown).
