This is a continuous steamer of a net conveyor type having a width of about 1000 to 2000 mm, and as shown in FIGS. 1 and 2, a beam 92 serving as a side wall surface of a steaming chamber 91. A pair of right and left sprockets 93 are attached to both front and rear ends of the, and a chain 94 is suspended on the sprockets 93. An endless belt-shaped conveyor net 95 is stretched over the chain 94 to form a net conveyor. The net conveyor rotates as the chain 94 rotates. A cover plate 96 is attached to the upper surface of the conveyor net 94, and a cover plate 97 is attached to the lower surface of the conveyor net 94, thereby forming a steaming chamber 91. 98 is provided, and the steam is blown out from the fumarole to steam the raw tea leaves transported on the conveyor net 95. The inclined conveyor 1 of the feeder is almost the same width as the conveyor net 15 of the feeder, and is inclined and mounted between the lower end on the starting end side of the machine frame 6 and the upper end on the leading end side. A dropping device is provided above the starting end, and the fresh tea leaves dropped from the dropping device are carried up to the tip and dropped there. In addition, a scraping claw 2 is provided on the upper surface of the inclined conveyor 1, and the raw tea leaves dropped from the dropping device are entangled with each other, and when the green tea leaves on the conveyor 1 are thicker than the others, this is used for scraping. Then, the whole is made to have a uniform thickness. The shooter 3 is formed in a gutter shape having substantially the same width as the inclined conveyor 1, the upper end of which is opened at the upper end of the inclined conveyor 1 at a position where fresh tea leaves fall, and the lower end thereof is connected to a net of a feeding steamer. Facing the beginning of the conveyor,
Fresh tea leaves falling from the inclined conveyor 1 are guided to a net conveyor. The distribution roller 31 is attached to the shooter 3 when the width of the net conveyor of the band feeding steamer is wide and the steaming chamber 91 is partitioned by the partition plate 99, and is located above the partition plate 99. Then, the raw tea leaves that are going to fall on the partition plate 99 are slid down from the side edges thereof so that they do not fall on the partition plate 99.
