Abstract

The invention discloses a microwave determination method for breakable beads in a breakable bead filter rod. The microwave determination method comprises the following steps: collecting breakable bead samples, and measuring the diameters Db of the breakable beads; collecting a breakable bead filter rod sample, measuring the density rholij of the part which does not contain the breakable bead of the filter rod, and finding out the maximum value rholmax of rholij; measuring the density rholij of the part containing the breakable beads of the filter rod, finding out the maximum value rohbihmax of the unit density of the part in which each breakable bead is located, and finding out the minimum value rhomin of rohbihmax; measuring the density of the breakable bead filter rod by virtue of a microwave resonance method by taking the length of 1mm or less as a measurement unit, and drawing a density curve of the breakable bead filter rod by taking the length as a horizontal axis and the density as a vertical axis; and reflecting the existence the breakable bead by virtue of the appearance of a peak value in the curve, reflecting the position offset of the breakable bead by virtue of the corresponding length of the peak value, and reflecting the damage condition of the breakable bead by virtues of the variation of the peak value. The microwave determination method is simple, the operation is easy, and the existence, position offset and damage condition of the breakable bead in the breakable bead filter rod can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of preparation and detection of filter rods for tobacco products, in particular to a microwave determination method for detonation beads in a detonation bead filter rod, in particular to a method for simultaneously measuring the presence or absence of detonation beads in a bead filter rod and the position deviation by using the principle of microwave resonance. The amount of displacement, the case of damage. Background technique [0002] In order to improve the taste of tobacco and reduce the harm of tobacco to the human body, tobacco companies have developed many new types of cigarettes, such as pearl cigarettes. As a new type of filter rod material, the blasting bead filter rod provides a good solution for forming the unique flavor and style of cigarettes. After the popping beads are crushed during the smoking process, the liquid in the rubber beads can make the cigarette more fragrant during the smoking ...
