Industrial plant essential oil extraction technology and equipment for middle part rotation diffusion negative pressure distillation

Abstract

The invention discloses an industrial plant essential oil extraction technology for middle part rotation diffusion negative pressure distillation. The industrial plant essential oil extraction technology comprises the following steps of pretreatment of materials, material throwing, introduction of steam in a middle part rotation diffusion manner under a negative pressure environment for distillation, condensation, cooling, oil-water separation and extraction of essential oil with a collection tank. The invention also discloses industrial plant essential oil extraction equipment for middle partrotation diffusion negative pressure distillation. According to the industrial plant essential oil extraction technology and equipment, by improving the distillation extraction technology and furtherimproving the distillation extraction equipment, the quality of the extracted essential oil is improved, the oil outlet efficiency of the equipment is improved at the same time, the energy consumption and the cost are lowered, easiness in material throwing and slag discharge of the equipment is realized, and production and use of industrial plant essential oil extraction are more facilitated.

Description

technical field [0001] The invention relates to the technical field of industrial plant essential oil production, and more specifically relates to a process and equipment for extracting industrial plant essential oil by cyclone diffusion negative pressure distillation in the middle. Background technique [0002] Essential oil, also known as aromatic oil or volatile oil, is an oily substance with characteristic aroma obtained from the flowers, leaves, roots, bark, stems, branches, fruits, seeds and other parts of aromatic plants. Due to its unique smell and strong volatility, essential oils have been widely used in canned food, beverages, cigarettes, cakes, cosmetics, soaps, detergents and other fields, especially in cosmetics. [0003] Because the essential oil is extremely volatile and easily soluble in organic solvents, the extraction methods of essential oil include steam distillation, extraction and pressing, and steam distillation is more widely used in actual productio...

AI Technical Summary

Problems solved by technology

In recent years, with the continuous rise of the essential oil industry, essential oil extraction equipment has also been greatly improved, but the existing industrial plant essential oil distillation extraction process generally still has the following problems: the distillation extraction process is too traditional, the extraction The quality of essential oil needs to be improved. At the same time, the oil output efficiency of the equipment is not high, and it is difficult to feed and slag, high energy consumption, and high cost.
