Tobacco product cigarette holder cooling performance testing device and method

Abstract

The invention discloses a tobacco product cigarette holder cooling performance testing device and method. The device comprises a support, an electric heating piece, an air inlet pipe, a first temperature sensor, a sealing ring, a computer, a second temperature sensor, an analog quantity signal transmitter, an air outlet pipe, a hose, a flow instrument and an air pump. The device is simple in structure and accurate in measurement result, and is convenient to operate. A temperature measuring element of the temperature sensor is not in contact with the tobacco or the cigarette holder, the structure of the cigarette holder is not damaged, the influence of the structures and properties of the tobaccos and the cigarettes of different brands and models on the test is avoided, the cigarette holdercan be tested independently, and then the cooling performances of the cigarette holders of different brands and models can be tested. According to the method, the temperature change of the smoke passing through the cigarette holder is simulated by simulating the inspiration action of a smoker and measuring the smoke temperatures before the smoke enters the cigarette holder and after the smoke exits the cigarette holder, and then the cooling efficiency is obtained through the ratio of the temperature change to the smoke temperature before the smoke enters the cigarette holder, so that the cooling performance of the cigarette holder can be accurately and objectively reflected.

Description

technical field [0001] The invention relates to the field of performance testing of tobacco products, in particular to a device and method for testing the cooling performance of cigarette holders of tobacco products, especially suitable for testing the cooling performance of cigarette holders of heat-not-burn cigarettes. Background technique [0002] The main harmful substances in traditional cigarettes are produced by pyrolysis of tobacco during the combustion process, and as the temperature rises, the content of harmful components such as aldehydes, benzene and its homologues, condensed ring aromatics, and CO in the smoke components increases. Non-burning cigarettes (also known as electric heating cigarettes, low-temperature cigarettes, etc.) use electric heating sheets to heat the tobacco at a low temperature so that it does not burn, and the nicotine and flavor substances in the shredded tobacco volatilize to produce smoke during heating. Because the tobacco does not bur...
