PURPOSE:To aim at enhancing the capacity of transfer of a conveyor for tea leaves, by attaching a retainer plate on the transferring surface of a belt conveyor, being spaced from the latter so that unroasted tea leaves are held between the retainer plates and the surface of the conveyor belt. CONSTITUTION:Unroasted tea leaves are set on the rear end of a belt conveyor 1 at a thickness which is larger than the space between the belt conveyor 1 and the retainer plate 4 made of acryl resin or the like on which unroasted tea leaves are liable to slip. At this time the rear end of the retainer plate 4 may be opened and closed, as indicated by the arrow, to be adapted to the amount of unroasted tea leaves. With this arrangement the unroasted tea leaves are advanced by means of the belt conveyor 1 and enter into the space between the retainer plate 4 and the conveyor 1 so that they are pressed against the transfer surface of the belt conveyor 1. With this arrangement, the unroasted tea leaves are formed into a thick layer-like shape and transferred as one unit body, thereby it is possible to enhance the transfer capacity of the conveyor for roasted tea leaves. |
