Source from:  TobaccoChina Online 08/05/2013

A tobacco leaf scrap stack curing research and application project executed by Chenzhou City Tobacco Company in south central China's Hunan Province has recently passed a stringent on-site appraisal for technical acceptance conducted by a group of experts organized by Chenzhou City Bureau of Science and Technology.

The project, officially known as Research and Application of Tobacco Leaf Scrap Stack Curing in the Tobacco-Growing Zone of Chenzhou, was executed in Linwu County of Chenzhou with assistance extended by Linwu County Tobacco Subcompany and other institutions.

The experts conducting the acceptance appraisal were from China Tobacco Hunan Industrial Co., Ltd., Hunan Provincial Tobacco Corporation, Changsha City Tobacco Company and Chenzhou City Agricultural Science Institute.

During the acceptance appraisal, the experts conducted on-site verification of the curing facilities, determined the relevant data, earnestly heard work reports and technological reports submitted by the taskforce designated to execute the project, checked the relevant data of the project, and raised questions and heard replies. On the basis of this, the experts unanimously reached consensus on the following points:

The taskforce designated to execute the project of Research and Application of Tobacco Leaf Scrap Stack Curing in the Tobacco-Growing Zone of Chenzhou, by means of optimizing curing technological and technical parameters, put forward on the basis of research a new model of stack curing of tobacco leaf scraps applicable to the curing of fresh leaf tobacco in tobacco-growing zones in southern China with a relatively high content of water.

In comparison with those adopting the technology of curing on strings, curing barns adopting the tobacco leaf scrap stack curing technology can hold 43 percent to 60 percent more leaf tobacco for curing, the cost of curing of leaf tobacco can go down by 30 percent, the proportion of orange leaves after curing can go up by 7.8 percent, the proportion of green or yellow leaves can go down by 0.6 percent, and the proportion of variegated leaves can go down by 0.4 percent. The adoption of this technology has contributed to initially solving hard technological problems from roughness or stiffness of tobacco leaves after curing.

Research under the project needs to be further deepened, and efforts for popularization of this technology should be gradually strengthened. Enditem
