DISTILLATION DEVICE, PROCESS USING THE DEVICE, DISTILLATION OF LIQUOR AND LIQUOR DISTILLED BY DISTILLATION PROCESS

摘要

PURPOSE:To distill efficiently even at the normal temperature and under normal pressure by setting an ultrasonic wave evaporator beneath the liquid surface of a material to be distilled in a distillation tank and emitting ultrasonic waves to atomize the material to be distilled and accelerate the distillation. CONSTITUTION:An ultrasonic wave evaporator 4 is set on a position immersed completely by a material to be distilled in a distillation tank 1, and pulse is supplied to the ultrasonic wave evaporator 4 by a circuit 3, and ultrasonic waves are emitted from the inside of the material to be cleaned to an inner-tank gas phase to generate the atomization and evaporation. At that time, the effect, in which the concentration of a certain component in mist formed by the ultrasonic wave emission is different from the general concentration of the component in the material to be distilled, is generated. For instance, ultrasonic waves are emitted from a liquor distillate or distillate filtrate in the distillation tank 1 to the inner-tank gas phase to accelerate the atomization and evaporation to generate the mist by the concentration of a low boiling point component containing ethanol which is higher than the concentration of the distillate or its filtrate. The vapor thus generated passes through a duct 12 and reaches a collecting column 13, and is cooled and concentrated by a zigzag tube 14 and collected into a distilled liquid storage tank 15 as distilled liquid 16.
