Method and device for measuring crushing degree of tobacco shreds

Abstract

The invention relates to a method and a device for measuring the crushing degree of tobacco shreds. By the established crushing degree measuring method, not only the capability and the level of a material incoming end working procedure can be represented, but also the mass variation of the crushed tobacco shreds can be reflected through a crushing process, so that the physical quality of final cigarette products can be predicted. By utilizing the method and the device, the crushing of the tobacco shreds in any process can be studied, the self anti-crushing property of raw materials can be reflected, and the influence of external force factors, such as process flows, conditions and the like on the anti-crushing property thereof can be studied. The invention has the following advantages: by directly measuring the crushing degree of the tobacco shreds, the anti-crushing ability of the tobacco shreds is represented correctly and the size distribution conditions of the tobacco shreds before being crushed and after being crushed are reflected; the invention is of great significance in predicting the processing quality of the tobacco shreds and provides an effective measure for studying the crushing process of tobacco shreds; meanwhile, the invention has advantages of low sampling quantity, simple operation and good method reproducibility. The designed special crushing device has reasonable structure and can simulate the crushing degree of any processing on the tobacco shreds.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a method and a device for measuring the crushing degree of shredded tobacco. The shredded tobacco can be shredded leaf, expanded shredded leaf, shredded stem, shredded shreds, shredded tobacco and the like used in cigarette production. Background technique: [0002] During the processing of cut tobacco, it will be gradually broken by different external forces. The degree of crushing of cut tobacco (or called resistance to breaking) is one of the important indicators to measure the quality of cut tobacco processing. The shredded tobacco is mainly determined by two main aspects. The first is the reason of the shredded tobacco itself. Different tobacco raw materials have different resistance to crushing due to their different physical and chemical properties; on the other hand, it is caused by external forces. In different processing processes, due to the different type...

Problems solved by technology

Unless there is a large difference in the degree of crushing of cut tobacco, this method cannot reflect the difference in the degree of crushing of different cut tobacco

Second, the test operation of the existing whole yarn rate is greatly affected by human factors. For example, different laying methods and laying thicknesses will cause large deviations in the results, which will cause errors in the change rate of the whole yarn rate.

The third is that this method needs to be sampled before and after rolling every time, which will inevitably affect the normal cigarette production process, and at the same time, due to the large amount of sampling, it will also cause a certain degree of waste of shredded tobacco

At the same time, it can be foreseen that there is a certain inaccuracy in the application of direct sampling methods for the difficult process of sampling on the production line.

For example, the passim cigarette machine, which is widely used at present, usually needs to be taken out for sampling, which makes the phenomenon of artificially destroying the structure of shredded tobacco appear.
