Description

Technical Field

[0001] The invention relates to the field of functional material testing, and in particular to a device for obtaining and evaluating the quality of flavor substances in tobacco flavoring particles and applications thereof. Background Art

[0002] Filter rods are an important component of cigarette products, and have the function of reducing the release of tar and harmful components. In addition, flavoring particles can be added to the filter rod to make a filter rod with flavoring function. The flavoring filter rod is directly applied to cigarettes, or combined with ordinary filter rods to form a multi-component composite filter rod and then applied to cigarettes. When the smoke flows through, the aroma components in the particles enter the consumer's mouth with the smoke flow, enriching the smoke and adding a special aroma. Starting from the non-combustion section of cigarettes, looking for relevant new materials to improve and enhance the aroma of cigarettes, increase the sweetness and salivation of cigarette smoke, and reduce the irritation of cigarette smoke has become an important research direction in this field.

[0003] CN109730355A discloses a method for preparing flavoring particles for cigarette filter rods, which mainly includes the following steps: firstly, kaolin, volcanic rock, tourmaline, perlite, medical stone, purple sand mud, diatomite, talcum powder, peat soil, and mica are ground, mixed, washed, sintered, and crushed to prepare porous particles, and then flavor substances are adsorbed on the porous particles to prepare flavoring particles. The flavoring particles are added to ordinary filter rods to prepare filter rods with flavoring function.

[0004] Generally, particles are applied to filter rods by applying them to a tow to form a composite filter rod, in the form of a binary composite filter rod or a cavity particle filter rod. When evaluating the effect of a flavoring particle in a filter rod, it is usually necessary to add the flavoring particle to the filter rod and then make a composite filter rod, including the following steps: 1) designing the particle application amount, and using a particle filter rod forming machine to prepare a composite filter rod, 2) designing a composite filter rod, and using a composite filter rod forming machine to prepare a particle composite filter rod, 3) placing the composite filter rod on a cigarette making machine for cigarette assembly, and making cigarettes for evaluation. This method involves too many processes, consumes a lot of manpower and material resources, and faces a large number of different types of materials, each of which needs to be trial-produced as a cigarette, which is inefficient.

[0072] This test example uses the method provided in Example 2 to test the roasted sweet coffee particles. Turn on the equipment switch, evacuate the air, empty the device, adjust the air intake to 30mL / s, and select a test tube (the test tube has a diameter of 7.7mm and a bottom area of ​​47mm 2 ), and then weigh 28 mg of particles and put them into the test tube. Turn on the temperature and humidity control module, the temperature change trend is that the first 200s is room temperature, suction is performed once every 50s on average, the air flow is adjusted to 30mL / s, the ventilation time is 1s, and from 250s to 450s, the temperature is linearly increased, and the air flow temperature is 48°C at 250s, 70°C at 300s, 82°C at 350s, 107°C at 400s, 120°C at 450s, and the air flow humidity is maintained at 64%.

[0073] Under the action of the suction airflow, the physical characteristics of the particles are observed through a transparent cylindrical tube.
