A method for measuring the passage time of tobacco leaves in drum processing equipment

Abstract

The invention relates to a determination method of the passing time of tobaccos in rattler type machining equipment. The determination method comprises the following steps: step 10) simultaneously feeding a plurality of tracking cloth sheets at an inlet of the rattler type machining equipment when the tobaccos pass through the rattler type machining equipment; step 20) recording the passing time of the tracking cloth sheets from the time point when the tracking cloth sheets are fed in the inlet of the rattler type machining equipment and appear at an outlet of the rattler type machining equipment as one-time passing time of the tracking cloth sheets; and step 30) repeating the step 10) and the step 20) for multiple times, and calculating a mean value of the plurality of passing times of the tracking cloth sheets, namely the passing time of the tobaccos in the rattler type machining equipment. With the adoption of the method provided by the invention, the influence on the continuity and the cigarette sensory quality of a production process in an existing testing method can be effectively avoided; the testing cost is reduced; the testing process is simplified; the test is effect and convenient.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for measuring the transit time of tobacco leaves in drum processing equipment. Background technique [0002] Transit time is the time it takes for a material to pass through a normally operating processing facility from entering to leaving. Loosening and re-moisture feeding are the key processes in the production process of cigarette shreds. The transit time of tobacco leaves in these processes is an important indicator. The length of transit time is related to the intensity of heat treatment of tobacco leaves and affects the sensory intrinsic quality of tobacco leaves. . Since the tobacco leaves are in a state of continuous flow in the loose dampening drum and the dampening feeding drum, it is difficult to test the passing time of the tobacco leaves in the drums. [0003] At present, the step method is commonly used in tobacco companies to test the passage ...

AI Technical Summary

Problems solved by technology

This method has the following disadvantages: ①The testing process is complicated and takes a long time; ②The feeding system at the entrance of the drum processing equipment is disconnected and then restarted, which will affect the continuity of production operations, affect the stability of equipment operation, and cause waste of tobacco leaves

[0004] In the prior art, there is also a method for measuring the passage time of tobacco materials. This method uses colored tobacco sheets as markers, uses the significant difference in color to find the markers at the exit of the process, and records the passage time of the markers from the entrance to the exit. The average value is the passing time of the tobacco material. This method also has certain disadvantages, such as: the production of markers is relatively complicated, and it is not convenient for actual operation; the tobacco leaves flow continuously in the drum, and they are not discharged together at the outlet. It is impossible to accurately determine whether the timing can be stopped; the dyeing agent is a non-tobacco material, and when the marker is not completely picked out, it will flow to the next process, which will eventually affect the sensory quality of the cigarette; manual selection of dyed tobacco slices is time-consuming and laborious
