Problems solved by technology

However, in the existing vacuum distillation method, since the vacuum pump has been pumping air during the distillation process to maintain the necessary vacuum degree, part of the essential oil cannot be effectively recovered after being pumped out by the vacuum pump, resulting in a greatly reduced yield of essential oil, which is also in actual production. One of the reasons why it is less used

Embodiment 1

[0027] As shown in the figure, the plant essential oil extraction device of the present invention includes a vacuum cycle extraction system composed of indirect heating vacuum evaporation unit I, condensation unit II and vacuum unit III connected in sequence. in:

[0028]An extraction structure 1 is provided in the indirect heating vacuum evaporation unit I. The extraction structure 1 has a sealable cavity space 4 with a venting structure 11, and a layered steam heating pipe with an external heating steam source 7, or a heating structure 6 in the form of a PTC connected to an external power supply ( Shown in the figure is a steam heating pipeline), which is matched with a tray-type material carrying structure 5 with a through-hole or grid ventilation structure. Wherein, a digital or pointer temperature display structure 2 and a vacuum degree display structure 3 are respectively provided in the airtight cavity space 4 . The gas outlet provided in the sealable cavity space 4 i...

Embodiment 2

[0032] use figure 1 The plant essential oil extraction device shown extracts rose flower essential oil.

[0033] The basic process of vacuum circulation extraction is to place 50kg of rose flowers in a vacuum circulation extraction system composed of sequentially connected indirect heating vacuum evaporation unit I, condensation unit II and vacuum unit III capable of internal / external circulation conversion. In the tray-type material carrying structure 5 with grid through holes between the layered heating structures 6 in the indirect heating vacuum evaporation unit, the vacuum degree of the extraction system is formed by the external circulation of the water ring vacuum pump in the vacuum unit. After the vacuum environment of 0.075MPa, switch to heating to 40-50°C under the condition of maintaining the vacuum degree of the extraction system and isolating the gas in the extraction system from the external environment, and circulating in the extraction system for 4 hours. Durin...

Embodiment 3

[0035] use figure 1 The plant essential oil extracting device shown, according to the operation process and the mode of embodiment 2, respectively take 50kg of sweet-scented osmanthus flowers as raw materials to extract the corresponding sweet-scented osmanthus essential oil. The basic process is basically the same as the above extraction of rose essential oil. The difference is that the cyclic extraction vacuum degree of the extraction system is -0.09MPa, and the cyclic extraction is carried out under the heating condition of 35-45°C for 5 hours. The liquid after the collected gas-liquid separation was left to stand for 4 hours to carry out oil-water separation, and the yield of the obtained sweet-scented osmanthus essential oil product was 0.03%.

Abstract

The invention discloses a plant essential oil extraction device and method. The plant essential oil extraction device is a vacuum circulation extraction system composed of an indirect heating vacuum evaporation unit, a condensing unit and a vacuum unit sequentially connected. The indirect heating vacuum evaporation unit has a closable chamber space respectively connected to an indirect heating source, a gas inlet and a gas outlet. The gas outlet is connected to the condensing unit. The gas inlet is connected to a vacuum pump of which a gas conveying path can be changed by a switching control structure. The gas conveying path changed by the switching control structure is arranged in an external environment direction or is communicated with the extraction structure closable chamber space. A vacuum gas pumping port of the vacuum pump is connected to a buffer structure in the condensing unit. The extraction device can realize circulation extraction of an essential oil-containing plant raw material under the condition of vacuum heating, effectively reduce an extraction heating temperature, effectively reduce or prevent the essential oil loss in the extraction process and improve plant essential oil product quality and an extraction yield.

Description

technical field [0001] The invention relates to a plant essential oil extraction device and a plant essential oil extraction method. Background technique [0002] Plant essential oils often have many benefits to the physical and mental health of the human body, and can be widely used to treat some sub-health diseases. At present, the main extraction method of plant essential oil is steam distillation. Steam distillation is a method invented by the Arab doctor Avicenna (AD 980-AD 1037) in the early eleventh century AD. Steam distillation has a history of nearly a thousand years since it was first invented. During this period, people have also made many improvements to related equipment and methods from multiple angles, such as equipment from the original wooden barrels, pottery equipment, to glass equipment, to stainless steel equipment, etc.; Pressure distillation, to pressure distillation, from water distillation to water distillation, etc., and microwave technology, ult...
