FIELD: tobacco industry.
SUBSTANCE: present invention relates to a method for electrical heating of cigarette tobacco. The method for electrical heating of cigarette tobacco includes a power supply source intended for supply of power to a heating device, a heating device connected to the power supply source, and a controller for control of a temperature of the heating device at a level of an operating temperature. At the same time, the electrical heating device additionally includes a temperature adjustment device for adjustment of an operating temperature, while the temperature adjustment device allows for establishment of a value of a temperature of the heating device in one of at least two operating temperature modes, while values of operating temperatures have a curve of a change in a temperature in time. In this case, the curve of a change in a temperature includes three stages: the first stage is a stage, at which a temperature of the heating device is increased from an initial temperature to the maximal temperature; the second stage is a stage, at which the temperature of the heating device is decreased from the maximal temperature to the operating temperature; and the third stage is a stage, at which the temperature of the heating device is maintained at a level of the operating temperature. At the same time, at the first stage, the temperature of the heating device is increased from the initial temperature to the maximal temperature T1 for time t1, while t1 is in the range of 1-25 seconds, the maximal temperature T1 is in the range of 220-250°C, at the second stage, the temperature of the heating device is decreased from the maximal temperature to the working temperature T0 for time t2, while t2 is in the range of 1-25 seconds, the working temperature T0 is in the range of 150-450°C, while its level is lower than the maximal temperature T1, at the third stage, the temperature of the heating device is maintained at the level of the working temperature T0 for time t3 until completion of an operation time period, wherein t3 is in the range from 118 seconds to 14 minutes and 20 seconds.
EFFECT: obtaining a method for electrical heating of cigarette tobacco.
