Cut tobacco mixing arrangement is used in laboratory

Technical Field

The invention belongs to the technical field of tobacco processing equipment, and particularly relates to a tobacco shred mixing device for a laboratory.

Background

The quality of tobacco leaves is the most important influence factor of the quality of cigarette products, and good cigarette products can not be separated. China is the first major country of tobacco leaf production in the world, but the yield of high-quality tobacco leaves is limited, the requirements of cigarette production cannot be met, the dependence on imported high-quality tobacco leaves is high, and therefore the contradiction that the supply of high-quality tobacco leaves is insufficient, the stock of low-quality tobacco leaves is overstocked, and the tobacco leaves cannot be effectively utilized is caused. Along with the rapid consumption and upgrade of the cigarette product market in recent years, the contradiction is increasingly prominent, and the contradiction becomes the biggest bottleneck restricting the development of the tobacco industry in China. In order to improve the quality of tobacco leaves, the properties of the tobacco leaves are mostly changed by adding biological agents into the tobacco leaves at present, and in the process of developing reagents, a certain amount of tobacco leaves are required to be frequently taken and added with the reagents to be fully mixed to study the influence of the reagents on tobacco shreds.

Present tobacco leaf and reagent equipment of mixing are mostly the main equipment on the production line, are not suitable for the laboratory to use, and consequently mostly be the manual work when the laboratory mixes and mix, and work burden is great, and the mixing precision is lower, appears mixing inhomogeneous problem easily, and reagent if not fully combines with the tobacco leaf, will cause the influence to subsequent data detection.
