Characterization method for drying processing strength of thin plate

Abstract

The invention discloses a characterization method for the drying processing strength of a thin plate. The method comprises: performing analysis based on two main objects of cut tobacco and hot air formass transfer in the thin plate drying process; transferring low-boiling-point volatile components in the cut tobaccos into hot air along with volatilization of moisture in the cut tobaccos in the thin plate drying process; the volatilization amount of low-boiling-point components in the cut tobacco being characterized by the volatilization amount of moisture in the cut tobacco, meanwhile, controlling the moisture mass transfer speed by the saturation degree, namely the moisture content, of hot air, and the drying processing strength of the thin plate being characterized from the two aspectsof the total mass transfer amount and speed of the cut tobacco and the hot air in the thin plate drying process. The quantitative method is adopted to represent the processing strength of the thin plate in the drying process, different tobacco shred processing strength is selected according to the quality characteristics and consumption requirements of cigarette products, and the tobacco shred processing technology is effectively guided.

Description

technical field [0001] The invention relates to a method for characterizing the dry processing strength of thin plates. Background technique [0002] In the tobacco industry, the process of making shreds is mainly to store the leaves after cutting them into shreds, heat and humidify (or not heat and humidify), and then dry them. After the dried shredded tobacco is cooled and shaped, it is blended and flavored. [0003] The drying process is a key process in the cigarette processing process, the purpose is to reduce the moisture content of the shredded leaf, improve the filling performance of the shredded leaf, and improve and enhance the sensory quality of the shredded leaf. At present, the drying methods commonly used in the tobacco industry include sheet drying and airflow drying. The setting of drying process parameters directly affects the physical quality and sensory quality of dried leaf shreds. Compared with other silk-making processes Especially obvious. The settin...
