Method for increasing sheeting rate of redried finished tobacco sheets

Abstract

The invention discloses a method for increasing the sheeting rate of redried finished tobacco sheets. The method comprises the steps that the tobacco sheets before drying and after peduncles and leaves are separated are fed to a screening device; the screened tobacco sheets greater than or equal to 25.40mm enter slitting equipment, the tobacco sheets between 3.18mm and 25.40mm enter a material collecting conveyer belt through a first temporary storage cabinet, and the tobacco sheets less than or equal to 3.18mm enter a tobacco chipping processing line through a chipping collector; the tobacco sheets greater than or equal to 25.40mm are cut into the tobacco sheets less than 25.40mm by the slitting equipment and enter the material collecting conveyer belt through a second temporary storage cabinet; the tobacco sheets mixed and matched uniformly on the material collecting conveyer belt are redried uniformly according to the conventional technology; and the redried finished tobacco sheets that are uniform in leaf size are obtained and then packaged for storage and alcoholization. With the method, the sheeting rate of the redried finished tobacco sheets is increased; harmony of middle and long shred proportion in the shredding process is improved; the problem that the shrinkage ratio of the tobacco sheets before and after redrying is high is solved; and the method is simple in procedure design, convenient to operate and relatively low in loss.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a method for increasing the rate of rebaking finished tobacco sheets. Background technique [0002] At present, many rebaking enterprises in China adopt the process of rebaking tobacco sheets of different sizes at the same time after separating the stalks and leaves. The unbalanced ratio has brought problems such as large slices not being roasted thoroughly, small slices being roasted, serious shrinkage of the slices before and after rebaking, uneven moisture in the box, and poor storage and fermentation effects. The proportion of short cuts is unbalanced, the filling value of cut tobacco is uneven, the phenomenon of cigarette tip falling is prominent, and the hardness and draw resistance of cigarettes fluctuate greatly, which in turn affects the stability of cigarette product quality. The patent CN1695505A proposes to sieve the large flakes after the thre...

Problems solved by technology

However, this method has problems such as difficult control of blade size, serious crushing and high energy consumption during processing.

Patent CN101589842A proposes to screen tobacco sheets of different sizes multiple times on the silk-making line, then cut tobacco sheets larger than 25.40 mm, and finally control the size of the tobacco sheets within the range of 6.35 to 25.40 mm for shredding, which can Effectively improve the uniformity of medium slice rate and leaf size, and reduce the ratio of excessively long leaf shreds after cutting, but this method has a complicated process and is easy to break, and short-term storage is difficult to control the stability of cigarette product quality
