FIELD: technological processes.
SUBSTANCE: wood is heated in water in closed volume up to temperature of 250°C and pressure that corresponds to this temperature. Then liquid temperature is reduced down to initial water temperature by means of four-stage reduction of pressure in closed volume and equalising of liquid temperature in every stage accordingly with pressure of this stage. At the first stage pressure is reduced down from 4.01-106 to 2.01-106Pa, at the second - from 2.01-106 to 1.01-106 Pa, at the third - from 1.01-106 to 5.01-105 Pa, at the fourth - from 5.01-105 to 1.01-105 Pa. After liquid temperature has been balanced, liquid is maintained in interval of its temperature reduction by 3-5°C. Then liquid is drafted.
EFFECT: invention allows to increase efficiency of smoking liquid preparation process.
