A method for dehumidifying tobacco leaves

Abstract

The invention discloses a tobacco leaf moisture removal method. A moisture removal room, dehumidifiers and a tobacco leaf frame are adopted for the tobacco leaf moisture removal method, wherein the tobacco leaf frame comprises three layers of tobacco-cooling frames; the minimum distance of the dehumidifiers and the tobacco leaf frame is larger than 1 m. The method comprises the steps as follows: firstly, tobacco leaves are paved horizontally on the tobacco-cooling frames in a single-bundle horizontally-placing manner, wherein the thickness of the tobacco leaves paved on each layer is no more than 10 cm; secondly, the dehumidifiers are started for raising the temperature in the moisture removal room to 35 to 40 DEG C, reducing the relative humidity to 55 percent to 65 percent, and maintaining the temperature and the relative humidity until the moisture content of the tobacco leaves is reduced to 13 percent to 15 percent, and the moisture removal is completed. According to the tobacco leaf moisture removal method, through the reasonable distribution of the dehumidifiers, the temperature in the moisture removal room reaches an optimal moisture removal temperature, and through the reasonable placement of the dehumidifiers and the tobacco leaf frame, as well as the elevation setting of the tobacco-cooling frames, hot air streams can circulate mutually through the capillary holes in the tobacco leaves, so that the effect of circulating and thorough moisture removal is achieved.

Description

technical field [0001] The invention relates to the field of tobacco leaf dehumidification, in particular to a tobacco leaf dehumidification method. Background technique [0002] Mold widely exists in nature. The mildew of tobacco leaves is due to the growth and reproduction of mold on tobacco leaves, which causes the content of tobacco leaves to be decomposed and consumed, and the normal tissue structure is destroyed. The appearance of the tobacco leaves invaded by mold is dull; the smell also changes from the original fragrance to an unpleasant musty smell; the taste of smoked smoke is bitter; resulting in the loss of use value, which will directly cause economic losses to enterprises or merchants. The mildew loss of tobacco leaves produced during the storage of tobacco leaves is quite alarming. According to statistics, Luzhou City purchases about 200,000 tons of tobacco leaves every year, and the use of conventional dehumidification methods results in the loss of tens o...

AI Technical Summary

Problems solved by technology

The shortcomings of traditional dehumidification are very obvious: uneven dehumidification of tobacco leaves, long dehumidification cycle, discoloration and deterioration of tobacco leaves, easy to break, and a large amount of loss during the dehumidification process
