Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flue-cured tobacco equipment, in particular to a tobacco adjustable sensor. BACKGROUND

[0002] In the process of curing tobacco, the moisture of the tobacco stem will also gradually be lost. In the early stage of curing tobacco, the stem flow rate may change due to the redistribution of water within the plant caused by the evaporation of leaf moisture. In the later stage of curing tobacco, stem flow almost stops, and the moisture content of the stem decreases to a very low level. By monitoring the change of stem moisture, the progress of curing tobacco can be determined when the stem moisture loss reaches a certain level and matches the dryness of the leaves. This can determine whether the curing process has reached the appropriate stage and provide a reference for adjusting the curing process. The stem sensor can reflect this process by detecting the change of stem moisture content or the reduction of stem flow. The stem sensor is fixed by a clamp. As the curing process progresses, the moisture content of the stem decreases, the stem flow rate slows down, and the stem shrinks, requiring adjustment of the clamp to prevent the stem sensor from falling off.
