Tobacco Threshing Equipments
The threshing process is next for the tobacco that has been cured. The leaf that has been cleaned and dried goes through a series of mechanical threshers and air separators. The drums and blades of the thresher pull the lamina off the stems, and the thresher makes a mix of lamina, stems, and leaves that haven’t been threshed.
Tobacco Leaf Processing
Whole tobacco leaves have a central stem (called a midrib) and a leaf (called a lamina). The midrib and leaf are separated mechanically at the tobacco leaf processing plant because they are used in different ways at the primary processing plant. The amount of moisture in these two parts is important for separating them (called “threshing”) and packing them into storage cases before making finished tobacco products. Moisture affects the taste, burn, fill, waste, and how the machine works.
Tobacco Clasifire
Air classifiers use the density difference to separate threshed lamina from unthreshed leaf and stem. Counterflow classifiers are very common in the process. The classified lamina comes through the conveyor to the final sieving section. The unthreshed leaf and stem go to the next thresher. The threshing and classification process continues at least 4 to 5 times till the stem and lamina completely separate. Tips blend with the threshed lamina before sieving. Then they pass onto the drier.
Tobacco Threshers
The tobacco leaf threshing and redrying pretreatment process is characterized in that firstly, according to the moisture condition of tobacco leaf raw materials, the moisture regaining time in a moisture regaining room of the tobacco leaf raw materials is determined, for the tobacco leaf raw materials with the moisture
Tobacco Classifire with Airlock
Rotary Airlock Feeder separates a pressure differential while allowing material to pass through it. Best way of thinking of how it works is imaging a revolving door in a building; it allows material to pass through, but maintains the pressure differential between the building and outside.
Taking Care Of Green Leaves And Stems
To get the harvested tobacco leaves ready for the mechanical threshing process, hot air and steam are used to make the leaves more flexible in cylinders. The conditioning cylinder is a rotating drum with steam jet nozzles that add moisture to the tobacco. Each steam jet nozzle can be controlled separately. The threshing process is next for the tobacco that has been cured.
