Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0039] Method example:

[0040] Such as figure 1 As shown, the tobacco leaf dynamic humidity control curing method of the present embodiment includes the following steps:

[0041] For the air-flow descending barn, by substituting the ambient temperature of the barn corresponding to each temperature control point in the tobacco leaf curing process into the previously determined temperature and humidity fitting equation of the upper barn of the barn, the environmental humidity of the upper barn of the barn corresponding to each temperature control point is obtained ; For the air-flow ascending barn, by substituting the ambient temperature of the barn corresponding to each temperature control point in the tobacco leaf curing process into the previous...

Abstract

The invention provides a control method and control system for dynamic-humidity-control baking of tobacco leaves, belonging to the field of tobacco leaf baking. The method comprises the steps that in a tobacco leaf curing process, curing control is conducted on tobacco leaves at each temperature control point according to a moisture removal rate corresponding to each temperature control point; for an airflow descending type curing barn, the moisture removal rate corresponding to the current temperature control point is calculated according to curing barn upper shed environment humidity corresponding to the current temperature control point and the previous temperature control point and the temperature holding time of the current temperature control point; for an airflow ascending type curing barn, the moisture removal rate corresponding to the current temperature control point is calculated according to curing barn lower shed environment humidity corresponding to the current temperature control point and the previous temperature control point and the temperature holding time of the current temperature control point, wherein the curing barn upper shed environment humidity corresponding to each temperature control point is obtained by using a curing barn upper shed environment temperature and humidity fitting equation; and the curing barn lower shed environment humidity corresponding to each temperature control point is acquired by using the curing barn lower shed environment temperature and humidity fitting equation. According to the invention, tobacco leaf curing quality can be effectively improved, and tobacco leaf curing loss is reduced.

Description

technical field [0001] The invention relates to a method and a control system for dynamically controlling the humidity of tobacco leaves and belongs to the technical field of tobacco leaf curing. Background technique [0002] Tobacco curing is the process of expressing the potential quality of fresh tobacco leaves and preserving them in the state of dry tobacco leaves. There are three core tasks of tobacco leaf curing: dehydration of leaves, yellowing of color and transformation of inner quality. Leaf dehydration means from 80% to 90% of the moisture content of fresh tobacco leaves to 5% to 10% after curing; the color turns yellow from the greenish yellow of fresh tobacco leaves to the orange yellow of roasted tobacco leaves; the internal quality transformation is from fresh tobacco leaves The aroma and taste of the roasted tobacco leaves meet the needs of cigarette formula use. The rational use of the curing process is the basis for the proper transformation of the tobacc...
