Изобретение относитс к эфиромасличной нромышленности, в частности к способам извлечени эфирного масла из растительного сырь , например хвои.The invention relates to the essential oil industry, in particular to methods for extracting essential oil from vegetable raw materials, such as needles.
Известен способ извлечени эфирного маела из растительного сырь в две стадии, на первой из которых сырье перегон ют с паром. Однако в известном способе на второй стадии сырье обрабатывают также паром, что не позвол ет полностью отогнать эфирное масло, а кроме того, извлечь ценные водорастворимые вещества.There is a method of extracting essential oil from vegetable raw materials in two stages, the first of which is used to distill the raw materials with steam. However, in the known method in the second stage, the raw materials are also treated with steam, which does not allow the essential oil to be distilled off completely, and in addition, to extract valuable water-soluble substances.
Цель изобретени - увеличение выхода масла и одновременное получение водорастворимых компонентов.The purpose of the invention is to increase the oil yield and at the same time obtain water-soluble components.
Дл этого на второй стадии сырье, прошедшее перегонку, подвергают гидродистилл ции, использу в качестве рабочей жидкости дистилл т после отделени эфирного масла на первой стадии, а водную выт жку отдел ют и упаривают, причем продолжительность паровой перегонки составл ет 1/5-1/3 общей продолжительности процесса.To do this, in the second stage, the distilled raw materials are hydrodistilled, using distillate as the working liquid after separating the essential oil in the first stage, and the aqueous extract is separated and evaporated, with the duration of steam distillation being 1 / 5-1 / 3 total process time.
Предлагаемый способ осушествл етс следующим образом.The proposed method is carried out as follows.
Измельченное эфиромасличное сырье, например хвою, подают в соответствующий аппарат , где его подвергают интенсивной паровой обработке. На этой (первой) стадии отгон етс до 90% эфирного масла и извлекаетс до Crushed essential oil raw materials, such as pine needles, are served in the appropriate apparatus, where it is subjected to intensive steam treatment. In this (first) stage, up to 90% of the essential oil is distilled off and extracted to
20% водорастворимых компонентов. Сырье во врем паровой обработки находитс в непрерывном движении. Затем сырье подвергают гидродистилл ции и при этом отгон ют оставшеес эфирное масло и извлекают водорастворимые компоненты (при обработке, например, хвои получают лечебный экстракт). Пары эфирного масла с первой стадии извлечени конденсируют, и после отделени первичного масла дистилл т подают на вторую стадию (гидродистилл цию) в качестве рабочей лсидкости , что способствует выделению из iero вторичного масла. Водна выт жка поступает на выпаривание.20% water soluble components. The raw material during steam treatment is in continuous motion. The raw material is then hydrodistilled and the remaining essential oil is distilled off and the water-soluble components are extracted (during treatment, for example, needles, a therapeutic extract is obtained). The vapors of the essential oil from the first stage of extraction are condensed, and after the separation of the primary oil, the distillate is fed to the second stage (hydrodistillation) as a working fluid, which promotes the release of secondary oil from iero. The water is drawn to evaporation.
Предлагаемый способ позвол ет повысить выход масла на 10-20%, а выход водорастворимых компонентов довести до 90-93% от их содержани в сырье.The proposed method allows to increase the oil yield by 10-20%, and the yield of water-soluble components can be increased to 90-93% of their content in the raw material.
Предмет изобретени Subject invention
Способ извлечени эфирного масла из растительного сырь , например хвои, в две стадии , на первой из которых сырье перегон ют с паром, отличающийс тем, что, с целью увеличени выхода масла и одновременного получени водорастворимых компонентов, на второй стадии сырье, прошедшее перегонку, подвергают гидродистилл ции, использу в качестве рабочей жидкости дистилл т после отделени эфирного масла на первой стадии. 3 а водную выт жку отдел ют и упаривают, причем продолжительность паровой перегон4 ки составл ет 1/5-1/3 обшей продолжительности процесса.The method of extracting the essential oil from plant materials, for example, needles, in two stages, the first of which is the raw material is distilled with steam, characterized in that, in order to increase the oil yield and at the same time obtain water-soluble components, the second stage, the distilled raw material hydrodistillation using distillate as the working fluid after the separation of the essential oil in the first stage. 3a, the aqueous extract is separated and evaporated, and the duration of steam distillation is 1/5 to 1/3 of the total process time.
