Abstract

The invention discloses a technological parameter adjusting method for improving threshing quality indexes, and relates to the technical field of tobacco processing. The method comprises the followingsteps: (1) selecting a one-beating one-linkage rotating speed, a one-beating five-linkage rotating speed, an eight-air-separation fan frequency, a four-air-separation fan frequency, a five-air-separation fan frequency, a two-beating one-linkage rotating speed, a three-air-separation fan frequency, a one-beating three-linkage rotating speed and a two-air-separation fan frequency as test factors; 2,..., 10); 2) calculating an index comprehensive score H0 of the current threshing process; 3) determining the horizontal interval of test factors; (4) predicting an index comprehensive score Hj (j =1, 2,..., 12) of the uniform test design sequence, (5) adjusting set values of process parameters, and (6) updating the horizontal interval of test factors. The threshing quality index predicted through the method is basically consistent with the actual index, the root mean square error is only 0.98%, and the process requirements are met.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a process parameter adjustment method for improving the threshing quality index. Background technique [0002] Leaf threshing and air separation is a process of separating leaves from tobacco stems under the action of wind force by mechanical means. The comprehensive quality of leaves after threshing and destemming is not only affected by the tobacco leaf type, region, position, grade and other external factors such as moisture content and temperature, but also closely related to whether the equipment process parameters are set reasonably. [0003] There are many process parameters and threshing quality indicators for threshing air classification, and the parameters and indicators interact and restrict each other, which makes it difficult to determine the relationship between threshing quality indicators and process parameters. The analysis of the threshing data of to...
