Abstract

The invention belongs to the technical field of tobacco leaf raw material storage and maintenance, and in particular relates to a method for measuring the loss of tobacco sheet storage process. The main technical idea of ​​this method is: based on the current storage and maintenance mode of laminar tobacco, select a sample of laminar tobacco, cut the block sample by the overall cutting method, put it into a non-woven bag, and place it in the tobacco storage box in situ Within the period, management is carried out according to the current tobacco leaf maintenance mode, and the loss of tobacco lamination process is calculated according to the weight change of experimental samples in different storage periods. This application provides a refined method for measuring the loss of the tobacco storage process. Compared with the existing extensive method for measuring and estimating the loss of the tobacco storage process, it can more accurately reflect the loss of the tobacco during the storage process, and at the same time Combined with the measurement results in different periods, it can reflect the law of tobacco storage loss, thus providing a more accurate basic support for the scientific setting of tobacco storage consumption indicators and the improvement of storage technology.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf raw material storage and maintenance, and in particular relates to a method for measuring the loss of tobacco sheet storage process. Background technique [0002] Lamina storage process loss is the normal loss of laminar tobacco in the process of natural alcoholization. The size and change of the loss have a certain relationship with the type, place of origin, grade and climate of the storage place, warehouse conditions and storage time. . But in general, the loss of tobacco laminar storage process depends on the intensity of self-heating and self-humidity of tobacco leaves. When the moisture content is suitable, the higher the temperature of the tobacco leaves, the deeper the enzyme action process will be, and the greater the process loss will be. [0003] In the existing researches, most of the studies on the storage of laminar tobacco at home and abroad are carried out from the aspect of...
