CENTRIFUGAL THIN-FILM DISTILLATION APPARATUS AND METHOD FOR EXTRACTIVE DISTILLATION OF BLACK PEPPER ACTIVE INGREDIENT USING SAME

摘要

The present invention provides a centrifugal thin-film distillation apparatus comprising: a distillation tank; one or more stacked rotary portions which rotate in the distillation tank so that a supplied solution can be applied to the entire inner circumferential surface of the rotary portion due to the rotational force; a heating portion for heating the rotary portion to a set temperature; a collecting portion which is arranged on the front end of the rotary portion in the circumferential direction and collects a solvent in which at least some solute is separated from the heated solution; and a discharging portion for sucking and discharging to the outside at least one solute which is separated from the heated solution while being evaporated. The present invention also provides a method for extractively distilling an active ingredient of black pepper by using the centrifugal thin-film distillation apparatus, the method comprising the steps of: supplying into the distillation tank a raw material or a solution to be separated; applying the supplied raw material or solution, along the circumferential direction, onto the inner circumferential surface of the rotary portion which is rotating; heating the rotary portion to a set temperature for a set time period while applying the solution onto the inner circumferential surface of the rotary portion; collecting heated solvent through a connecting portion at the outer region of the rotary portion; and discharging an evaporated solute via a through hole of the rotary portion. Accordingly, the first-grade pepper that is uncrushed whole pepper suitable for active ingredients is used, and raw material pepper carefully selected, from harvesting to washing and drying, is used to obtain the piperine active ingredient in black pepper.
