Tobacco

Within the many production stages of tobacco processing, conveyor belts play an essential role. Whether it is the picking or sorting of leaf bundles, redrying, bale opening, cigarette wrapping or packaging; YONGLI offers one of the widest product ranges of TPO or TPEE conveyor belts on the market.

Generally, processes within the tobacco industry can be divided into three segments:

Grean leaf processing
Primary processing
Secondary manufacturing

YONGLI TPO and TPEE coated tobacco belts comply to FDA, USDA, EU and Japan Regulations. Additionally, they are pyrolysis conformable, meaning the belt material won't release hazardous substances during combustion, a standard specifically demanded by the tobacco industry.

Especially TPEE coated conveyor belts ensure great wear resistance and good performance at high as well as low temperatures.

Green leaf processing
Tobacco leafs arrive from the farms to the processing plants where moisture is added to make the tocacco pliable enough to take out the stems, a process called threshing. Afterwards the tobacco is dryed and compressed into bales. All automated processes involving many conveyor belts at challenging circumstances. The tobacco bales a strored for a long period of time before they are ready for use in cigarettes.
Primary processing
Around 2 years after the green leaf processing, the tobacco can be ready for the next step in cigarette production. The bales are opened and conditioned, a process including relatively high temperatures and a very humid environment. Once the tobacco reaches the right levels, it can be cut, blended, dryed and stored for the last time.
Secondary manufacturing
The tobacco arrives at the plant where the actual cigarettes are produced following a highly automated process. The tobacco is placed on a paper and rolled to become one large rod. It is then cut to individual cigarettes in various stages. Once the filter is inserted the finished cigarettes are packed. From individual packs, to cartons, to transport boxes.
Pyrolysis conformable
The tobacco industry demands strict standards for the usage of conveyor belts. One of the criteria is that the belt passes the Pyrolysis test. This is a combustion test at 800 degrees, in which the released gases are analyzed to make sure they are free of nitrogen, sulphur, chlorine and fluorine.
