Method for non-destructively detecting segmented suction resistance of cigarettes

Abstract

The invention relates to a method for non-destructively detecting segmented suction resistance of cigarettes and belongs to the technical field of cigarette quality detection. The method utilizes thebasic feature of flow conservation and quasi-series of air flows passing through a cigarette, realizes measurement of the suction resistance of each part of the cigarette based on a cigarette suctionresistance measurement method, independently acquires closed suction resistance data of a filter tip section and a cigarette section without mechanically separating the filter tip section and the cigarette section, determines that the permeation resistance of the whole filter tip laser-punched cigarette is composed of five permeation resistance values according to the cigarette suction resistanceformation theoretical basis that the pressure of flows passing through the cigarette is in direct proportion to the amount of flows passing through the cigarette and the ratio is cigarette permeationresistance (unit: Pa. s / ml) which is a physical property parameter, and calculates segmented suction resistance values of all parts of the cigarette. The method can satisfy the actual engineering demands of providing the basic support for cigarette product quality traceability, product design and process optimization.

Description

Technical field: [0001] The invention relates to the technical field of cigarette quality detection, in particular to a method for non-destructive detection of segmental draw resistance of cigarettes. Background technique: [0002] Cigarette draw resistance is one of the important indicators of the physical quality of cigarette products, and its size has an important impact on the sensory quality and smoking difficulty of cigarette products. The measurement of the draw resistance of cigarettes usually adopts GB / T 22838.5-2009 "Determination of Physical Properties of Cigarettes and Filter Rods_Part 5: Cigarette Draw Resistance and Pressure Drop of Filter Rods", which can realize the fully automatic operation of cigarette draw resistance measurement With control, the above method realizes the measurement of cigarette open draw resistance and closed draw resistance. Through the measurement of cigarette draw resistance, we can know the quality of cigarettes and the level of cig...

Problems solved by technology

However, in the implementation, since it is assumed that the cigarette paper and the shredded tobacco section are connected in parallel (this relationship is only applicable to a certain range of use), it is easy to appear that a section of draw resistance shows a negative value during detection.
