Problems solved by technology

[0006] However, the reason why heat-not-burn tobacco products have not been widely accepted is mainly due to the unsatisfactory smoke release performance and smoke sensory quality of the currently used cigarette core materials in the heat-not-burn state

Embodiment 1

[0039] Connect the heating device of the present invention to a single-channel smoking machine in an appropriate manner, weigh an appropriate amount of shredded tobacco, fill it in the filling cavity of the suction pipe, and set the heating temperature to 300°C. The ISO suction mode is used, that is, the suction volume is 35mL, the suction time is 2s, and the suction cycle is 60s. The suction tubes equipped with shredded tobacco are sucked, and each tube sucks 10 puffs. The gaseous particulate matter is captured on a Cambridge filter disc. Standard methods were used to analyze the total particulate matter, nicotine, and moisture in the flue gas.

Embodiment 2

[0041] Fill the tobacco extract into the suction tube filling cavity of the heating device of the present invention, and set the heating temperature to 250°C. The evaluation team is composed of more than 7 provincial judges. The Canadian deep suction mode is adopted, that is, the suction volume is 50mL, the suction time is 2s, and the suction cycle is 30s. Take 10 puffs, and evaluate the mouth-by-mouth and overall feelings from the aspects of smoke characteristics and aroma characteristics.

Abstract

A heating device suitable for smoke analysis and evaluation under the heating and non-combustion conditions of tobacco materials is characterized by comprising a cylindrical heating body, a suction pipe mounted in the cylindrical heating body in a sleeved mode and a temperature control mechanism connected with the heating body. The cylindrical heating body is composed of a cylindrical shell and a heating pipe arranged in the cylindrical shell. The space between the cylindrical shell and the heating pipe is filled with thermal insulation materials. The suction pipe is composed of a suction nozzle, a suction pipe body and a tobacco filling cavity, wherein the suction nozzle, the suction pipe body and the tobacco filling cavity are connected in sequence. The rear portion of the suction pipe is mounted in a pipe cavity of the heating pipe. The temperature control mechanism is composed of a temperature sensor inserted in the pipe cavity in the rear portion of the heating pipe and a control box electrically connected with the heating pipe and a sensor. The heating device has the advantages that the design is simple, temperature control is accurate, temperature rise is rapid, and the requirement for sensory evaluation and chemical analysis of released smoke of various tobacco materials with different properties or other fragrance generation materials under the heating and non-combustion conditions at different temperatures can be met.

Description

[0001] technical field [0002] The invention belongs to the technical field of tobacco, and in particular relates to a heating device suitable for analysis and evaluation of flue gas in a state of heating and non-combustion of tobacco materials. Background technique [0003] Heating-not-burning tobacco products are a new type of tobacco products, which can promote the contained tobacco materials to generate smoke for consumers to smoke in a non-burning state through heating. Compared with traditional cigarettes, sidestream smoke and some harmful The release of substances is significantly reduced. Heat-not-burn tobacco products were first launched by Reynolds Tobacco Company. Although this type of product has not been widely recognized by the market, due to the continuous increase in global tobacco control efforts and its obvious potential in reducing environmental pollution and smoking health risks The international tobacco field has always believed that this type of produ...
