Abstract

The invention discloses a temperature-lowering granule for reducing the temperature of heat-not-burn cigarette smoke and a preparation method thereof. The low-temperature decomposition compound, base material and binder are used as raw materials and prepared through wet granulation technology. The cooling particles of the present invention use the decomposition and endothermic characteristics of low-temperature decomposition compounds to cool down the smoke, and when added to cigarette products, there will be no thermal deformation after heating, no mutual adhesion between the particles, and no blockage of the flow of smoke. The decomposition products do not affect the flue gas quality, and the raw materials are easy to obtain, the price is low, the preparation method is simple, and the industrial production is easy.

Description

technical field [0001] The invention belongs to the technical field of novel tobacco products, and in particular relates to a temperature-lowering particle for reducing the temperature of heat-not-burn cigarette smoke and a preparation method thereof. Background technique [0002] Low-temperature heating cigarettes are one of the important categories of new tobacco products. This "heat-not-burn" method enables tobacco to be heated only at a lower temperature (ideal temperature range 450-550°C), avoiding the burning of tobacco when it burns. The high temperature environment results in the formation of tar and a large number of harmful compounds. Moreover, since there is basically no sidestream smoke, second-hand smoke will not be generated, and the public environment will not be affected, which alleviates the contradiction between smoking and smoking bans in public places to a certain extent. [0003] Due to the short length of heat-not-burn cigarettes, the smoke at the entr...
