Abstract

The invention provides a filter stick stability evaluation method and a microwave density detector, and belongs to the technical field of cigarette quality detection. The filter stick stability evaluation method comprises the following steps of: S1, detecting the density distribution of a filter stick; S2, drawing the density distribution curve of the filter stick; S3, removing the distortion density data at two ends of the filter stick; S4, the solving the range of the density mean value of each split section of the single filter stick, carrying out segmentation processing on detection data according to the splitting quantity of the filter stick, solving the density mean value of each split section, and then calculating the range of the density mean value of each split section; S5, solving the mean value of the density range of each split section of 20 filter sticks, solving the range p pole of the density mean value of each split section of each filter stick according to S2, and thensolving the mean value of the density range of the 20 filter sticks. The method has the characteristics of simplicity and feasibility, can quantitatively characterize the stability condition of the filter sticks, can characterize the quality consistency of the split filter sticks, and has important guiding significance for cigarette process control and process analysis.

Description

technical field [0001] The invention belongs to the technical field of cigarette quality detection, and in particular relates to a method for evaluating the stability of a filter rod and a microwave density detector. Background technique [0002] The filter rod is an important part of a cigarette, and its quality stability directly affects the stability of the draw resistance of the cigarette, which in turn affects the mainstream smoke and sensory quality of the cigarette. At present, standard deviation and other methods are mainly used to evaluate the stability of filter rods, mainly focusing on characterizing the stability between filter rods. However, the filter rod is only connected to the cigarette after being cut, so the stability of the internal quality of a single filter rod also directly affects the stability of the cigarette. [0003] At present, domestic cigarette manufacturers have begun to use the microwave method to detect the density of filter rods, but there...
