Problems solved by technology

The problem now is that the moisture value and the target value often have a certain deviation, that is, the target value is 18%, but the average leaf moisture after balance is not stable, sometimes it will be below 17% when it is low, and sometimes it will be below 17% when it is high. To more than 19%, it will have a great impact on the stability of product processing quality

Abstract

The invention relates to a loosening moisture regain machine capable of improving the stability of the leaf moisture content and a control method. The control method comprises the following steps that firstly, the water addition is kept unchanged, different steam flows are set through a steam regulating valve, the moisture of leaves discharged from a material discharging port is detected through a moisture detector, and a numerical value of the moisture of the leaves is recorded; secondly, the steam addition is kept unchanged, different water additions are set through a water regulating valve, the moisture of leaves discharged from the material discharging port is detected through the moisture detector, and a numerical value of the moisture of the leaves is recorded; thirdly, a relation of equivalence between influences of steam on the moisture of the leaves and influences of water on the moisture of the leaves is obtained. According to the control method for improving the stability of the leaf moisture content, a total water addition ratio is set, so that the moisture of the tobacco leaves is more even and more stable after the leaves are loosened and the moisture is regained and the technical quality of products is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a loose moisture conditioner and a control method for improving the stability of the moisture content of blades. Background technique [0002] The loosening and moisture regaining process is an important process in the tobacco processing process. To process packaged tobacco from the rebaking factory, the moisture content of the tobacco leaves needs to be controlled at about 12% to facilitate long-term storage. If the moisture content is too high, mildew will easily occur, and if the moisture content is too low, it will easily break during processing. The loosening and moisture regaining process is to loosen the sheet tobacco with a moisture content of 12% and increase the moisture content of the tobacco leaves to about 18% (technical requirements), so as to meet the processing requirements of the subsequent process. [0003] Since the laminar tobacco entering the drum is a form...
