Problems solved by technology

There are three main problems in the current heating and humidification process of tobacco leaves in the pretreatment section of threshing and re-cured tobacco leaves: (1) The vacuum re-moisture process is intensive, and the tobacco leaves are subjected to high-temperature and vacuum treatment during the re-moisture process, resulting in a large loss of tobacco aroma

Abstract

The invention relates to the technical field of a threshing and redrying process for tobacco, in particular to a method for improving the moisture uniformity of a threshed and redried tobacco material. The method comprises a primary hot air tobacco moisturizing procedure and a secondary hot air tobacco moisturizing procedure, and is characterized in that a tobacco storage cabinet is arranged between the primary hot air tobacco moisturizing procedure and the secondary hot air tobacco moisturizing procedure to store the tobacco material after the primary hot air tobacco moisturizing procedure for 40 to 80 minutes, and the moisture balancing time of the tobacco material is prolonged and the moisture uniformity of the threshed and redried tobacco material is improved by adjusting the water adding amount and air temperature technical parameters of primary hot air tobacco moisturizing and secondary hot air tobacco moisturizing. Based on moisture absorption and moisture liberation characteristics of the tobacco material, the invention provides a complete and feasible preprocessing process flow and control technology for threshed and redried tobacco for improving the moisture uniformity of the threshed and redried tobacco material, and the breakage of the tobacco in the threshing process is further reduced by adopting the preprocessing process flow and control technology for the threshed and redried tobacco.

Description

technical field [0001] The invention belongs to the technical field of threshing and redrying technology, and mainly relates to a new pretreatment process and control technology for threshing and redrying tobacco leaves that improve the moisture uniformity of tobacco leaf raw materials. Mainly on the basis of the current pretreatment process of threshing and re-cured tobacco leaves, tobacco leaf storage cabinets are added between the first hot air moistening process and the second hot air moistening process, and by increasing the storage time of tobacco raw materials after the first moistening, Moreover, the temperature of the tobacco leaves is increased through the secondary moistening of the leaves, the moisture uniformity of the raw materials of the threshing and re-cured tobacco leaves is improved, and the crushing of the raw materials of the tobacco leaves in the threshing process is reduced. Background technique [0002] Tobacco redrying is a sorting and preparatory pr...
