and acquiring the total air permeability according to the preset ventilation rate.
The air permeability of the filter ventilation zone closest to the suction end is obtained according to the total air permeability, and the aperture and the number of the filter ventilation holes of the corresponding filter ventilation zone are obtained through the air permeability of the filter ventilation zone closest to the suction end. The air permeability of the filter ventilation zone closest to the suction end may be obtained based on a set percentage (e.g., 70%) of the air permeability of the filter ventilation zone closest to the suction end to the total air permeability. The air permeability is determined by the aperture and the number of the vent holes, so that the aperture and the number of the vent holes can be obtained according to the air permeability.
Since the air permeability of the filter ventilation zone closest to the suction end is most significant in enhancing the smoke temperature sensation and improving the lack of tobacco flavor, the parameters of the ventilation holes of the filter ventilation zone closest to the suction end are determined first.
And (3) punching holes on the cigarettes according to the aperture and the number of the filter ventilating holes of the filter ventilating area closest to the suction end to obtain a plurality of preset cigarettes. The pore diameter and the number of the ventilation holes of the filter ventilating area closest to the smoking end on a plurality of preset cigarettes are the same.
Acquire the quantity and the air permeability in surplus filter tip ventilation district and pipe tobacco ventilation district according to total air permeability to obtain the filter tip ventilation hole in corresponding filter tip ventilation district and the pipe tobacco ventilation hole's in pipe tobacco ventilation district aperture and number by the air permeability in surplus filter tip ventilation district and pipe tobacco ventilation district. The number and air permeability of the remaining filter ventilation zones and tobacco ventilation zones may be obtained based on a set percentage (e.g., 30%) of the air permeability of the remaining filter ventilation zones and tobacco ventilation zones to the total air permeability. The air permeability is determined by the aperture and the number of the vent holes, so that the aperture and the number of the vent holes can be obtained according to the air permeability. The air permeability of each subarea obtained by the filter tip ventilation areas and the tobacco shred ventilation areas with different quantities is different.
And punching holes on the preset cigarettes according to the aperture and the number of the filter tip ventilation holes of the different residual filter tip ventilation areas and the tobacco shred ventilation holes of the tobacco shred ventilation areas to obtain a plurality of test cigarettes. The aperture and the number of the ventilation holes of the filter ventilating areas closest to the suction end on different test cigarettes are the same, and the number of the remaining filter ventilating areas and the number of the tobacco shred ventilating areas are different, and the aperture and the number of the ventilation holes of each ventilating area are different.
And (4) performing sensory evaluation on the test cigarettes, and screening according to sensory evaluation scores to obtain the target cigarettes. Generally, the higher the sensory evaluation score is, the most obvious effects of improving the smoke temperature sensation and the insufficient tobacco fragrance are shown, and the relevant parameters of the test cigarette with the highest score are the parameters of the target cigarette.
The preparation method of the graded ventilated cigarette can quickly and efficiently obtain the number of filter tip ventilating areas and tobacco shred ventilating areas of a target cigarette and the aperture and the number of the vent holes of each ventilating area.
