Description

Cooling filter rod and smoking article comprising same
Technical Field
The present application relates to a cooled filter rod and a smoking article comprising the same.
Background
In the heating type tobacco rod, in order to generate smoke smell in the medium portion (including substances generating smoke smell and aerosol including tobacco raw materials such as tobacco shreds and flavors), it is necessary to use special equipment for heating. The conventional heating type special device for a tobacco rod, which has been developed so far for generating smoke smell, is designed to have a temperature program for realizing high-temperature heating in consideration of the transfer to the inside of the medium part. The heating temperature is generally between 200 ℃ and 400 ℃, and a large amount of water vapor is generated when the medium part cigarette rod is heated by equipment, unlike the traditional cigarette in which tobacco shred is burnt for inhalation. The temperature of the medium part inside due to heating reaches 100 ℃ to 200 ℃. The temperature of the air flow generated inside the medium section reaches a similar level, and if no cooling element is provided downstream of the medium section, the smoker may inhale the hot air.
At present, development and research on cooling elements for reducing the cost and improving the functions of the novel heating type cigarette rod are very active.
