The response frequency of the pressure measurement system 5 is 1 KHz, and the range is -5KPa, data acquisition frequency 100Hz.

[0046] The above-mentioned device is used for measurement and evaluation, and the process is as follows:

[0047] Select a certain brand of slim cigarette 2 for detection, first carry out air leakage inspection and suction capacity correction on the cigarette suction system 6 according to the conditions stipulated in the national stand...

Embodiment 3

[0049] The difference from Embodiment 1 is that in this embodiment, the tubular pressure probe 3 is a hollow glass tube with a length of 60 mm, an inner diameter of 0.7 mm, and an outer diameter of 0.8 mm; the tubular joint 4 is a hose with an inner diameter of 0.8 mm , the length is 60 mm; one end of the tubular joint 4 is set on the end of the tubular pressure probe 3, and the other end is set on the pressure sensor. The pressure measurement system 5 has a response frequency of 1KHz, a measuring range of -3KPa, and a data collection frequency of 100Hz.

[0050] The above-mentioned device is used for measurement and evaluation, and the process is as follows:

[0051] Select a certain brand of slim cigarette 2 for detection, first carry out air leakage inspection and suction capacity correction on the cigarette suction system 6 according to the conditions stipulated in the national standard GB / T16450-2004; smoke the cigarette 2 according to the set suction parameters, and dete...

Abstract

The invention discloses a device for measuring change of pressure drop in burning period of cigarette in real time and a method thereof. The device comprises a cigarette clamping device, a tubular pressure probe, a pressure testing system, a tubular joint, a cigarette suction system and a data processing system, wherein the cigarette suction system is provided with a suction pipe, and the suctionpipe is in sealed connection with the cigarette clamping device; the input end of the data processing system is connected with the output end of the pressure testing system; the inner diameter of thetubular pressure probe is 0.5 to 1.0mm, and the outer diameter of the tubular pressure probe is 0.6 to 1.1mm. One set of device and method for measuring the change of pressure drop in burning period of cigarette is built. The device has the advantages that the device is connected with the cigarette suction system, the change of pressure drop in the burning process of the cigarette can be monitoredin real time, and the burning condition in the cigarette suction process can be dynamically detected; the important study meaning is realized, and the industry blank is filled.

Description

technical field [0001] The invention belongs to the technical field of quality control of filter tip materials in the tobacco industry, and in particular relates to a device and method for real-time measuring the change of internal pressure drop during cigarette burning. Background technique [0002] Cigarette draw resistance is an important parameter affecting the internal quality of cigarettes and the formation and distribution of smoke, and it is also one of the important quality indicators controlled by cigarette industry enterprises. For consumers, the perceived cigarette draw resistance is the resistance (pressure drop) during the smoking and burning process, and they will adjust their smoking behavior according to the change of pressure drop. At the same time, the change of pressure drop during cigarette combustion also directly affects the combustion state of cigarettes, so it is necessary to study the pressure drop and its change during cigarette smoking and combust...
