A method for making shredded tobacco with uniform length

Abstract

The invention discloses a method for making shredded tobacco with uniform length. The blade is divided into leaf base and leaf tip, and the leaf tip is cut into strips, and the leaf tip is cut into a width consistent with the distance between cutters. Uniform tobacco rods, leaf tip section Ⅰ and leaf base threshed and destemmed tobacco slices are mixed and rebaked, boxed, and the tobacco rods of leaf tip section Ⅱ are conveyed with the belt and fall into the slots of the conveyor belt in sequence. The mesh-belt redrying and drying equipment packs the tobacco rods into boxes according to the length after redrying. The tobacco rod box is alcoholized according to the normal alcoholization method of tobacco sheets, and then sent to the silk-making process. After opening the box, increasing temperature and regaining moisture, it is cut in parallel to the direction of the cutter in the width direction, and the finished product is made by leaf shreds feeding and drying. cut tobacco. The manufacturing method of shredded tobacco with uniform length starts from the process of threshing and redrying, and by adjusting the manufacturing process of shredded tobacco, the uniformity of shredded tobacco length is significantly improved, the length concentration is greatly improved, and the quality and stability of cigarette products are significantly improved.

Description

technical field [0001] The invention belongs to the technical field of cigarette shredded tobacco processing, in particular to a method for making shredded tobacco with uniform length. Background technique [0002] The length distribution of shredded tobacco refers to the ratio of shredded tobacco of various lengths to the overall mass. Excessively high percentages of super-long shreds or short shreds in finished shredded tobacco will result in poor blending uniformity, which will affect the cigarette’s cigarette density, draw resistance, hardness, and edge drop. Physical quality indicators such as silk quantity, and then affect the sensory quality of cigarettes. Therefore, it is of great significance to reduce the percentage of super-long filaments and short filaments of shredded tobacco and make shredded tobacco with uniform length distribution to improve the physical quality and smoking quality of cigarettes. [0003] At present, the means to improve the uniformity of th...

Problems solved by technology

The above methods of controlling the length of shredded tobacco will cause excessive shredding of shredded tobacco during use, resulting in a high rate of short shreds and shredded shreds, which not only increases consumption, but also causes fluctuations in cigarette quality

Patent No. CN103892431A discloses a threshing and redrying process based on leaf cutting to improve the uniformity of the tobacco sheet structure. A screening device is used to sieve the tobacco leaves into qualified tobacco sheets and large tobacco sheets with a maximum size greater than 10 mm. Cutting into qualified tobacco sheets by cutting leaves can improve the uniformity of the tobacco sheet structure, but due to the inconsistent feeding angle of the tobacco sheets during the shredding process, the uniformity of the length of the shredded tobacco after cutting cannot be greatly improved
