Silica gel cooling section of heat-not-burn product

Abstract

The invention relates to a silica gel cooling section of a heat-not-burn product, which is a tubular cooling section consisting of straight-through hole smoke channels with different section shapes and channel walls surrounding the smoke channels, and can be directly connected with a smoking section and the like to be rolled into a cigarette with a binary structure or a cigarette with a structureof more than two elements. The silica gel cooling section has characteristics of high air permeability, high specific heat capacity and good heat resistance, the smoke temperature is reduced through evaporation heat absorption of bound water in silica gel and specific heat capacity dual cooling of the silica gel, no thermal collapse or melting condition occurs in the suction process, the smoke concentration is improved, the smoke temperature is reduced, and smoke purification efficiency is improved; loaded aroma substances are rich in cigarette aroma, so consumption experience of consumers issatisfied.

Description

【Technical field】 [0001] The invention belongs to the technical field of tobacco processing. More specifically, the present invention relates to a heat-not-burn product silica gel cooling section. 【Background technique】 [0002] It is well known that smoking is harmful to health, especially with the development of society and the continuous improvement of people's living standards, people are paying more and more attention to their own health problems. For smokers, how to smoke cigarettes safely is a key point in the development of tobacco technology direction. Heat-not-burn cigarettes are cigarettes that use electronic equipment to heat tobacco substances at 300-500°C instead of burning tobacco substances. During the smoking process of this kind of cigarettes, no open flames and soot are produced, which is environmentally friendly and enables consumers to pass electronic cigarettes. Heating equipment can feel the aroma of tobacco when smoking cigarettes, and at the same t...

However, in addition to the physical changes during the phase transition process, the chemical changes are also accompanied. After the polylactic acid is melted at high temperature, the shrinkage and melting of the polylactic acid film will appear after the suction, which will block the smoke channel and affect the taste.
