  In leaf leaf filling and leaf tobacco picking operations, dust that is generated in each operation and flies around the work table passes through the gaps between many pipes arranged in the frame by operating the exhaust fan. It is efficiently collected in the dust collection chamber at the lower part of the work table, and is collected through the exhaust duct connected to the exhaust fan. As a method for collecting dust, a dust collecting unit equipped with a filter may be provided in the middle of the exhaust duct. This improves the working environment of the leaf tobacco drying workplace.

  The exhaust capacity of the exhaust fan may be as long as the flow velocity of the air passing through the gap between the pipes of the work table from top to bottom is very low to low (average of about 0.5 m / sec to 2.0 m / sec). Dust can be collected efficiently at a flow rate in the range. When the flow rate becomes medium to high (3.0 m / sec to 5.0 m / sec), the leaf tobacco on the pipe is sucked onto the pipe, and not only foreign matter but also the leaf tobacco is sucked from the gap between the pipes to the floor surface. There is a risk of falling on top or deforming the leaves.

  In leaf leaf filling work or dry leaf picking work, foreign matter such as soil, sand, vinyl pieces, and threads attached to the leaf tobacco is allowed to fall freely down through a long gap between the pipes of the work table, and the leaf tobacco is removed. Can be collected separately. When a vinyl piece, thread, or the like is caught on the pipe, the vinyl piece, thread, etc. caught on the pipe can be reliably dropped by pushing and rotating the rotatable pipe by the operator. As a result, the leaf tobacco remains on the pipe, and all other foreign matters fall below the work table, and the leaf tobacco and the foreign matters can be completely separated.
