Method for prolonging heat preservation time of heated tobacco

Abstract

The invention provides a method for prolonging the heat preservation time of heated tobacco. The method comprises the following steps that: tobacco is provided, the tobacco comprises tobacco shreds and non-metal materials, the non-metal materials have the characteristics of high heat capacity and high heat conductivity, the heat capacity of the non-metal materials is larger than that of the tobacco shreds, energy absorbed by the non-metal materials is larger than that absorbed by the tobacco shreds after first-time heating, and after smoking is completed, residual heat of the non-metal materials is conducted / radiated to the tobacco shreds; after secondary heating, the tobacco shreds and the non-metal materials continue to absorb energy, and after smoking is completed, residual heat of thenon-metal materials is conducted / radiated to the tobacco shreds to preserve the heat of the tobacco shreds, so that the characteristics of heat transfer, energy compensation and heat preservation in the tobacco shreds are achieved. Especially for tobacco shreds far away from a heat source, heat cannot be directly transmitted / radiated, and the non-metal materials serve as a secondary heat source and have a heat preservation function.

Description

technical field [0001] The invention relates to a method for increasing the heat preservation time of heated tobacco. Background technique [0002] Present cigarette, it comprises cigarette paper, is coated with shredded tobacco in the cigarette paper, is mixed with combustion accelerant in the shredded tobacco, to utilize the ignition of cigarette, and one end of shredded tobacco is provided with filter cotton, is also called filter stick, and during use, the cigarette sticks Placed in a smoking appliance, the smoking appliance includes a heating needle and a storage cavity, the heating needle is located in the middle of the storage cavity, the heating needle is connected to a power supply, the control board controls the output power of the power supply, and the heating needle is inserted into the shredded tobacco to realize the Tobacco is heated, the tobacco is energized to generate heat, and the heat is transferred from the center to the edge of the tobacco. The heated ar...

AI Technical Summary

Problems solved by technology

The heating needle in the center of the cigarette proceeds to the edge in the form of heat transfer. Since the heat conduction speed of the shredded tobacco itself is slow and the heat capacity of the shredded tobacco is small, the shredded tobacco in the center is completely heated, while the shredded tobacco at the edge is still in an unheated state. Heating, when the shredded tobacco in the center is burnt, the shredded tobacco at the edge may not be fully heated, and the heat is distributed in a gradient from the center to the edge of the cigarette, that is, the center temperature is high, and the temperature is lower as it goes outward. The shredded tobacco can only pass 5mm, and the radius of the cigarette is 10mm. In any case, it is impossible to heat the shredded tobacco beyond 5mm, which leads to the aroma of the shredded tobacco at the edge not being evaporated, or the taste of the cigarette is extremely bad. Burnt smell, burnt smell, normal aroma of shredded tobacco mixed together
