Problems solved by technology

[0004] The patent application CN2018104868613 previously submitted by the applicant relates to a cooling filter rod, which is solidified and molded by cooling particles coated with phase change materials on the surface. The cooling effect is outstanding, but because the selected body material itself has good adsorption capacity, When used to heat non-burning cigarettes, the amount of smoke is greatly reduced. At the same time, the heat stored in the phase change cooling process cannot be dissipated in time. When smoking, it will bring a burning sensation to the lips, which affects the smoking experience.
[0005] Chinese patent specification CN101396173 discloses a method for cigarette eddy current cooling and fragrance preservation and its cigarette structure. The eddy current channel is set in front of the cigarette filter to be the same as the air to achieve the cooling effect. The structure is relatively complicated and not suitable for low-temperature heating and non-burning cigarettes.

Embodiment 1

[0043] In this example:

[0044]1) Preparation method of cooling granules: In terms of parts by mass, take 20 parts of 80-mesh polyethylene and 80 parts of ethylene / vinyl acetate copolymer. After mixing evenly, use a commercial screw extruder to blend, melt, extrude, granulate and spheronize. Take 20-35 mesh particles to obtain low-adsorption cooling particles, and the particle bulk density is 3.0g / ml; 2) Preparation method of cooling particle sticks: The prepared low-adsorption cooling particles are continuously sent to three serially distributed through the conveyor belt. Cavity components (structural schematic diagram as figure 2 shown), the center of the mold cavity is a circular channel with a circumference of 23.5mm. The first mold cavity is provided with a negative pressure to compress and accumulate the particles in it. After being wrapped with cloth tape, it is sent to the second mold cavity with a heating device. The granules in the mold cavity are heated to 120°C,...

Abstract

The invention relates to a cooling filter stick as well as a preparation method and application thereof. The cooling filter stick is of an integrated stick-shaped structure formed by bonding and curing low-adsorption particles, has stable network-shaped porous morphological characteristics, can provide a complex and smooth smoke channel, and can greatly reduce the temperature of smoke entering anoral cavity mainly based on a physical cooling principle on the premise of not adopting a ventilation and dilution means. The cooling filter stick prepared on the basis of low-adsorption particle forming has little influence on the smoke amount, and the smoking taste is good. The full-particle rod formed by curing the low-adsorption particles is simple in form and novel in structure, industrial continuous production can be achieved, the suction resistance is small, and the suction resistance and the cooling amplitude can be adjusted.

Description

technical field [0001] The invention relates to a cooling filter rod, a preparation method and an application thereof, and belongs to the technical field of cigarette production. Background technique [0002] During the traditional cigarette smoking process, the heat generated by the cigarette burning cone will be carried to the filter by the mainstream smoke, and the temperature of the smoke passing through the filter will gradually increase as the cigarette is smoked. Studies have shown that the temperature of the flue gas at the filter tip can reach as high as 70-80°C near the end of smoking. Excessively high filter tip temperature will affect the interception effect of the filter tip and affect consumers' evaluation of the sensory quality of the flue gas. It is necessary to properly reduce the flue gas temperature. [0003] Generally, heat-not-burn cigarettes use external heating elements to heat tobacco products to generate smoke. Usually, tobacco products reach atomiz...
