Vegetable oil extracting device

Abstract

The invention discloses a vegetable oil extracting device and aims at providing a vegetable oil extracting device which is simple in structure and convenient to operate. The vegetable oil extracting device comprises a steam generator, a distilling still, a condenser and an oil-water separator, wherein a water draining tube and an oil removing tube are arranged at the lower end of the oil-water separator, a first valve is arranged on the water draining tube, and a second valve is arranged on the water removing tube; a first branch tube communicated with the bottom of the distilling still is arranged at the upper end of the steam generator; a hose communicated with an inlet of the condenser is arranged on the end cover of the distilling still; a second branch tube communicated with an inlet of the oil-water separator is arranged in the outlet of the condenser; and a third branch tube communicated with the upper part of the steam generator is arranged in an outlet of the water draining tube of the oil-water separator. The vegetable oil extracting device is used for heating and distilling materials in the distilling still by virtue of the steam generated in the steam generator. The vegetable oil extracting device disclosed by the invention is high in distilling speed, capable of shortening the distilling time and lowering the energy consumption. Moreover, components with a high boiling point can be steamed out of the high temperature steam, and the oil extraction rate is high.

Description

technical field [0001] The invention relates to the technical field of vegetable oil extraction, in particular to a vegetable oil extraction device. Background technique [0002] Steam distillation is the most common and widely used method for extracting vegetable oil from plants. The existing common method is to put the materials of aromatic plants into the steamer first, and then add clear water to heat directly. The raw materials in this method are always submerged in water, the water dispersion effect is good, the distillation is more uniform, and the steam short circuit will not be caused by the hardening of the raw materials. However, the ratio of solid to liquid is very large, the time required for heating and distillation is long, and the energy consumption is large. The condensate distilled from some vegetable oils is severely emulsified, and oil-water separation is difficult. Decomposition, the quality of vegetable oil is difficult to guarantee.
