Embodiment Construction

[0028] Concrete technological process of the present invention is further detailed as follows:

[0029] 1 Preparation of cigar samples:

[0030] 1.1 Conditioning of cigar samples:

[0031] 1.1.1 Adjust the atmosphere:

[0032] Temperature: 22℃±1℃ Relative humidity: (60±2)%

[0033] Note: Atmospheric pressure should be within 96kPa±10kPa. Atmospheric pressure shall be tested and reported in the test report.

[0034] 1.1.2 Adjustment time

[0035] It takes at least 72 hours for a cigar to equalize under forced airflow.

[0036] 1.1.3 Balance test

[0037] A cigar sample is considered balanced if it meets one of the following criteria:

[0038] a) Within 24 hours, the relative change in the mass of cigars is not more than 0.1%;

[0039] b) When the cigars are placed in a closed container of comparable volume, the relative humidity in the container is the same as that of the specified conditioned atmosphere.

[0040] 1.2 Cigarette marking

[0041] For closed-mouth ciga...

Abstract

The invention provides a method for detecting suction resistance of a cigar, which can accurately detect the suction resistance of a cigar without destruction and is suitable for detecting cigar samples in different appearance specifications. The invention also provides a method for calculating air flow rate in the suction resistance detection process. The method for detecting the suction resistance of a cigar is characterized by comprising the following steps: a, preparing a cigar sample; b, preparing a cigar test head; c, calculating the air flow rate; and d, detecting the suction resistance of the cigar. By using the method, related operations for suction resistance detection of the cigar are specified, and accuracy, repeatability and reproducibility of the suction resistance detectingresults of the cigar are well guaranteed.

Description

technical field [0001] The invention relates to a cigar smoke analysis technology, in particular to a method suitable for measuring the draw resistance of cigar smoke. Background technique [0002] When analyzing cigar smoke, it is necessary to measure the draw resistance of cigar smoke in advance. However, in the prior art, there is still a lack of a method for measuring the draw resistance of cigars, so establishing an accurate and reliable method for measuring the draw resistance of cigars is very important for the analysis of cigar smoke. However, cigars come in a wide range of shapes and sizes, ranging from about 65 mm to 250 mm in length, from less than 1 g to more than 15 g in weight, and from about 6 mm to 25 mm in diameter. The shape of cigars is also very inconsistent, some are approximately cylindrical, some are approximately conical, especially the shape of the cigar mouthpiece is very different. Therefore, the method for measuring the draw resistance of cigars...
