摘要：Shredded tobacco is supplied from a storage reservoir to one or more cigarettemaking machines by way of discrete pneumatic conveying pipes. The reservoir receivesfresh tobacco at regular or irregular intervals so that the quantity of tobacco in itsinterior is constant. The contents of the reservoir are maintained in suspension so that atleast the major part of the supply of tobacco shreds forms a fluidized bed which islocated directly below the intakes of the conveying pipes. When a machine requires abatch of tobacco shreds, the respective pipe is connected to a suction generating deviceso that it draws air from the region between the underside of the fluidized bed and theupper side of the bottom wall of the reservoir whereby the ascending current of airentrains tobacco particles directly from the fluidized bed. The supply of tobacco in thereservoir can be converted into a fluidized bed by mechanically agitating the reservoir sothat the shreds move up and down and/or by causing a plurality of streamlets ofcompressed air to rise through perforations in the bottom wall of the reservoir. Thelatter may have a circular, semicircular or polygonal cross-sectional outline.
