СПОСОБ ПОЛУЧЕНИЯ ТАБАЧНОГО МАСЛА ОБЛАСТЬ ТЕХНИКИ METHOD FOR PRODUCING TOBACCO OIL TECHNICAL FIELD
Изобретение относится к способам производства масел из растительного сырья и может быть использовано для получения жирного масла из высокомасличных отходов табачных плантаций - семян табака.The invention relates to methods for the production of oils from plant materials and can be used to obtain fatty oils from high-oil waste from tobacco plantations - tobacco seeds.
ПРЕДШЕСТВУЮЩИЙ УРОВЕНЬ ТЕХНИКИBACKGROUND OF THE INVENTION
Известен способ получения масла табачного из семян табака, включающий очистку семян, детоксикацию и прессование с выделением масла, для чего проводят двукратное прессование, при этом на первое прессование направляют очищенные семена с получением масла табачного с сохранением натуральных свойств и жмыха, который направляют на детоксикацию, и второе прессование с получением масла табачного технического (предварительный патент PK N° 13562, кл. С 11 В 1/00, 2003). Указанный способ .не обеспечивает высокой степени очистки, поэтому полученное масло неприменимо для медицинских целей.A known method of producing tobacco oil from tobacco seeds, including cleaning the seeds, detoxification and pressing with the release of oil, for which double pressing is carried out, while the purified seeds are sent to the first pressing to obtain tobacco oil with preserving natural properties and oilcake, which is sent for detoxification, and second pressing to obtain technical tobacco oil (provisional patent PK N ° 13562, class C 11 B 1/00, 2003). The specified method. Does not provide a high degree of purification, therefore, the resulting oil is not applicable for medical purposes.
Известен способ получения медицинского табачного масла из семян табака, включающий очистку семян табака, их прессование с выделением масла, разделение на жидкую и твердую фракции, после чего проводят отстаивание полученной жидкой фракции не менее трех суток и последующую трехкратную фильтрацию с получением масла табачного медицинского (предварительный патент PK N° 17646, кл. С 11 В 1/06, 2006).A known method for producing medical tobacco oil from tobacco seeds, including cleaning tobacco seeds, pressing them with oil separation, separation into liquid and solid fractions, followed by sedimentation of the obtained liquid fraction for at least three days and subsequent triple filtration to obtain medical tobacco oil (preliminary Patent PK N ° 17646, class C 11 B 1/06, 2006).
Процесс отстаивания жидкой фракции не менее 3 суток усложняет способ, кроме того, в процессе длительного отстаивания происходит насыщение масла токсичными компонентами, которые экстрагируются из осадка. Трехкратная фильтрация дополнительно усложняет способ и приводит к значительным потерям целевого продукта. Известен способ получения масла табачного, включающий очистку семян табака, их двукратное прессование с выделением масла и разделением на жидкую и твердую фракции. Жидкую фракцию масла отстаивают не менее 5 суток, отделяют от осадка и подвергают трехкратной фильтрации (предварительный патент PK Na 18858, Kn. C I l B 1/06, 2007).The process of sedimentation of the liquid fraction for at least 3 days complicates the method, in addition, in the process of prolonged sedimentation, the oil is saturated with toxic components that are extracted from the sediment. Threefold filtration further complicates the method and leads to significant losses of the target product. A known method of producing tobacco oil, including the cleaning of tobacco seeds, their double pressing with the release of oil and separation into liquid and solid fractions. The liquid oil fraction is left to stand for at least 5 days, separated from the precipitate and subjected to threefiltration (preliminary patent PK Na 18858, Kn. CI l B 1/06, 2007).
Отстаивание жидкой фракции не менее 5 суток (более 120 часов) приводит к экстрагированию токсичных компонентов из осадка, что ухудшает качество готового продукта и требует его дополнительной очистки. Трехкратная фильтрация приводит к значительным потерям целевого продукта.The sedimentation of the liquid fraction for at least 5 days (more than 120 hours) leads to the extraction of toxic components from the sediment, which affects the quality of the finished product and requires additional purification. Threefold filtration leads to significant losses of the target product.
РАСКРЫТИЕ ИЗОБРЕТЕНИЯSUMMARY OF THE INVENTION
Задачей изобретения является разработка способа производства масла из высокомасличных отходов табачных плантаций для использования масла в медицинских и косметических целях.The objective of the invention is to develop a method for the production of oil from high oil waste from tobacco plantations for the use of oil for medical and cosmetic purposes.
Достигаемый результат - повышение качества табачного масла, упрощение способа и снижение степени экстракции токсичных компонентов из осадка за счет сокращения времени отстаивания, а также уменьшение потерь целевого продукта.The achieved result is an increase in the quality of tobacco oil, a simplification of the method and a decrease in the degree of extraction of toxic components from the sediment by reducing the settling time, as well as reducing the loss of the target product.
Указанный результат достигается тем, что в способе получения табачного масла, включающем очистку семян табака, их прессование с разделением на жидкую и твердую фракцию, отстаивание жидкой фракции с выделением масла и его фильтрацию, согласно изобретению, перед прессованием проводят детоксикацию семян раствором гидроксида натрия, жидкую фракцию после прессования отстаивают в течение 20 - 48 часов, а перед фильтрацией, которую , осуществляют двукратно, очищают масло активированным углем, выдерживая не менее 1,5 часов при температуре 25 - 40 ° С. Проведение детоксикации семян табака перед прессованием снижает уровень загрязнения готового продукта токсичными компонентами.This result is achieved by the fact that in the method for producing tobacco oil, which includes cleaning seeds of tobacco, pressing them with separation into a liquid and a solid fraction, settling the liquid fraction with the release of oil and filtering it, according to the invention, before pressing, the seeds are detoxified with a solution of sodium hydroxide, liquid after pressing, the fraction is defended for 20 to 48 hours, and before filtration, which is carried out twice, the oil is cleaned with activated carbon, keeping at least 1.5 hours at a temperature of 25 - 40 ° С. Detoxification of tobacco seeds before pressing reduces the level of contamination of the finished product with toxic components.
Отстаивание жидкой фракции в течение 20 - 48 часов достаточно для отделения осадка. При отстаивании меньше 20 часов процесс выделения масла происходит не полностью, а отстаивание более 48 часов приводит к экстрагированию маслом из осадка токсичных компонентов, которые не были удалены в процессе детоксикации..The sedimentation of the liquid fraction for 20 to 48 hours is enough to separate the precipitate. When settling for less than 20 hours, the process of oil separation is not complete, and settling for more than 48 hours leads to the extraction of toxic components from the sediment that were not removed during the detoxification process.
Очистка масла активированным углем позволяет получить ценный продукт, не имеющий вредных для организма компонентов. При этом температура выдержки 25 - 40 ° С является оптимальной для очистки.Purification of oil with activated carbon allows you to get a valuable product that does not have components harmful to the body. Moreover, a holding temperature of 25 - 40 ° C is optimal for cleaning.
Снижение температуры менее 25 ° С замедляет процесс очистки, а повышение температуры , более 40 ° С нецелесообразно, так как предварительная детоксикация семян была проведена и оставшиеся токсичные компоненты могут быть полностью удалены при указанных условиях. А повышение температуры более 40 ° лишь увеличит энергозатраты на нагрев.Lowering the temperature less than 25 ° C slows down the cleaning process, and increasing the temperature, more than 40 ° C is impractical, since preliminary detoxification of the seeds was carried out and the remaining toxic components can be completely removed under these conditions. A temperature increase of more than 40 ° will only increase the energy consumption for heating.
