Steam distillation aromatic essential oil equipment

Abstract

The invention discloses steam distillation aromatic essential oil equipment. The equipment comprises a distillation kettle, a complex distillation column, a goose neck pipe, a cooler and an oil-water separator, wherein a double-layer hollow steam coil pipe is horizontally and fixedly arranged at the bottom in the kettle body of the distillation kettle; the inner pipe of the double-layer hollow steam coil pipe is connected with steam outlet pipes which are distributed annularly and are communicated with the inner pipe of the double-layer hollow steam coil pipe and penetrate through the outer pipe of the double-layer hollow steam coil pipe in a liquid sealing way; the included angle between the extension lines of the steam outlet pipes and the vertical axis in the kettle body of the distillation kettle is 30 to 40 degrees. The steam distillation aromatic essential oil equipment has the benefits that the outer pipe of the hollow steam coil pipe can be prevented from being overheated, and the aromatic petals in contact with the outer pipe are prevented from being burnt, so that the aroma quality of the aromatic essential oil is improved; the steam sprayed from the steam outlet pipes drives the aromatic petals and water to move in the spraying direction of the steam and to roll downward along the inner wall of the kettle body of the distillation kettle, so that the aromatic petals are steamed and cooked uniformly, the distillation time is shortened, and the oil yield is improved.

Description

technical field [0001] The invention belongs to a fragrance distillation equipment, in particular to equipment suitable for steam distillation of rose essential oil. Background technique [0002] At present, the production of flower aromatic essential oils mainly adopts the steam distillation process. The quality of the flower aromatic essential oils produced by the steam distillation method is good. Water and aromatic flowers are added to the distillation kettle of the steam distillation equipment, and the water vapor passes through the bottom of the still body. The coil enters the interior of the still to heat the water. After boiling, the aromatic flowers are cooked to generate mixed steam. The mixed steam enters the condenser to condense into a mixed liquid, and the mixed liquid enters the oil-water separator to separate the aromatic essential oil. However, the steam coil at the bottom of the still body of the existing distillation equipment is overheated, which easily b...

AI Technical Summary

Problems solved by technology

However, the steam coil at the bottom of the still body of the existing distillation equipment is overheated, which easily burns the aromatic flowers that come into contact with, and makes the distilled aromatic essential oil have a burnt smell, which affects the aroma quality of the aromatic essential oil.

In addition, the water and aromatic flowers in the still still only rely on boiling and steam impact movement, so the distillation is uneven, especially when the amount of flowers added is more, the distillation is even more uneven, which reduces the oil yield of aromatic flowers. In order to prevent scorching, a protective net is installed in the distillation kettle to isolate the steam coil, which intensifies the unevenness of distillation and reduces the oil yield
