Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tobacco processing, more particularly, relates to a primary curing tobacco leaf green removing device and a green removing method thereof. BACKGROUND

[0002] Tobacco leaf stacking and curing is a key process for promoting fermentation, volatilizing green and miscellaneous odor, and improving aroma and quality by stacking tobacco leaves. The tobacco leaf support frame can isolate the tobacco leaves from the ground to avoid direct contact with the humid ground, which can cause local humidity to be too high and cause mold. At the same time, it can make the air circulate inside the tobacco pile, so that all the tobacco leaves can uniformly absorb moisture and transform, avoiding the occurrence of green smoke or uneven fermentation due to excessive stacking pressure.

[0003] Currently, there are still the following problems when removing green from primary curing tobacco leaves: 1. When the primary curing tobacco leaves are placed, the position of the primary curing tobacco leaves needs to be adjusted by the staff, which affects the placement efficiency of the primary curing tobacco leaves; 2. The placed tobacco leaves need to be bundled and fixed by the staff, which cannot realize the rapid auxiliary compression of the tobacco leaves, and also affects the placement efficiency of the tobacco leaves; 3. When the placement height of the tobacco leaves is low, the staff cannot be automatically prompted to supplement the tobacco leaves in time. SUMMARY
