Detailed Description
The technical solution provided by the present application is described in more detail below with reference to fig. 1 to 4.
The embodiment of the application provides natural spice preparation equipment which comprises an extraction tank 1, a heat exchange structure and an oil-water separator 3. A first channel 4 is formed between the outlet of the oil-water separator 3 and the inlet of the extraction tank 1, and a second channel 6 is formed between the outlet of the heat exchange structure and the inlet of the extraction tank 1; wherein the first channel 4 and the second channel 6 can be alternatively conducted. When the first channel 4 is conducted, the fluid output by the extraction tank 1 can flow into the extraction tank 1 through the heat exchange structure, the oil-water separator 3 and the first channel 4. When the second channel 6 is conducted, the fluid output from the extraction tank 1 can flow into the extraction tank 1 via the heat exchange structure, the second channel 6.
The natural perfume is plant essential oil or tincture. The outlet of the extraction tank 1 of the natural perfume preparation device is communicated with the inlet of the heat exchange structure, and the outlet of the heat exchange structure is simultaneously communicated with the inlet of the oil-water separator 3 and the inlet of the extraction tank 1, so that a second channel 6 is formed between the outlet of the heat exchange structure and the inlet of the extraction tank 1, and a first channel 4 is formed between the outlet of the oil-water separator 3 and the inlet of the extraction tank 1. The whole natural perfume preparation device can form two loops: the first circuit allows the fluid to flow in the following direction: extraction tank 1, heat exchange structure, oil-water separator 3 and extraction tank 1, wherein the loop is used for extracting plant essential oil. The second circuit allows the fluid to flow in the following direction: extraction tank 1 → heat exchange structure → extraction tank 1, this circuit is used for extracting tincture.
Therefore, the natural spice preparation equipment provided by the technical scheme can realize continuous extraction of plant essential oil and tincture.
Referring to fig. 1, the heat exchange structure includes a first heat exchanger 21, a second heat exchanger 22, and a third heat exchanger 23. The outlet of the first heat exchanger 21 is in communication with the inlet of the third heat exchanger 23, and the outlet of the third heat exchanger 23 is in communication with the oil-water separator 3 and the second channel 6. The outlet of the third heat exchanger 23 is also in communication with the inlet of the second heat exchanger 22, and the outlet of the second heat exchanger 22 can be normally open. The second heat exchanger 22 is used to condense the vapor which is not completely condensed by the third heat exchanger 23, and the condensed liquid flows out through the vapor inlet primary.

The first channel 4 is present partly at the same level as the natural fragrance outlet of the oil-water separator 3. This makes it possible to equalize the pressure in the first passage 4 with the pressure at the natural perfume discharge port of the oil-water separator 3, prevent occurrence of siphoning, and realize multiple extraction of natural perfume.
When the first loop is adopted independently, plants can be added into the extraction tank 1 for multiple times, so that the extraction of plant essential oil in multiple batches is realized; when the second loop is adopted independently, plants can be added into the extraction tank 1 for a plurality of times, so that the extraction of tincture in a plurality of batches is realized. It will be appreciated that the extraction of the tincture can be carried out by means of a second circuit, after the extraction of one or more batches of plant essential oils has been carried out by means of a first circuit. Alternatively, after one or more batches of essential oil extraction is performed using the first circuit, different extractants are added in a single or multiple times using the second circuit to achieve multiple extractions of natural fragrances.
Therefore, the natural spice preparation equipment provided by the technical scheme can realize continuous extraction of the plant essential oil and the tincture, and can realize multiple extraction of the plant essential oil and the tincture.
Referring to fig. 1, some control valves may be used to control the on or off of the first channel 4, as follows: the first channel 4 is provided with a fourth control valve V4 and a fifth control valve V5, a first end of the evacuation pipe 5 is connected to a portion of the first channel 4 located between the fourth control valve V4 and the fifth control valve V5, and a second end of the evacuation pipe 5 communicates with an inlet of the second heat exchanger 22 through an eighth control valve V8, the first control valve V1.

When the natural perfume preparation device is used for extracting plant essential oil, the first channel 4 is communicated, and fluid output by the extracting tank 1 can flow into the extracting tank 1 through the heat exchange structure, the oil-water separator 3 and the first channel 4. When the natural spice preparing apparatus is used for tincture extraction operation, the second channel 6 is in communication and fluid output from the extraction tank 1 can flow into the extraction tank 1 via the heat exchange structure, the second channel 6.

The first to fourth steps are plant essential oil extraction steps.
Step five: a certain amount of extraction solvent is added to the extraction tank 1.
In the fifth step, the extraction solvent can be water, ethyl acetate, 5-95% ethanol, etc.; the quality of the plant is 3-15 times of that of natural plants.
Step six: the control valves V1, V5, V6 and V8 are opened and the control valves V2, V3, V4 and V7 are closed, thus forming the second circuit described above.
Step seven: after the steam heating device of the jacket of the extraction tank 1 is started and the set temperature is reached, the solvent condensate is condensed and flows back to the extraction tank 1 through the sixth control valve V6 and the fifth control valve V5.
In the seventh step, the opening of the steam heating valve is 0-100% according to the process parameter setting; the temperature range can be room temperature-solvent boiling point (such as solvent water, the temperature range can be room temperature-100 ℃); the condensing flow rate of the solvent condensate can be 0-80 Kg/h.

In the eighth step, the time range may be 0.5-4 hours.
The fifth to eighth steps are tincture extraction steps. The tincture extraction process is not necessarily performed after the plant essential oil extraction process, and the tincture extraction process may be performed alone.
Step nine: the natural plant residues in the extraction tank 1 are discharged and the next batch of natural plants is continuously added.
Step ten: and (3) repeating the second step and the eighth step, so that the essential oil in multiple batches can be collected once or multiple times.
According to the natural spice preparation equipment provided by the technical scheme, the valves V1-V8 are opened or closed to form two different condensate reflux processes, so that single-batch or multi-batch continuous production can be realized by switching according to the needs, and a good practical effect can be achieved in production. Meanwhile, the eighth control valve V8 is designed, so that the technical defect that essential oil cannot be collected due to the fact that the oil-water mixed liquid in the oil-water separator 3 flows back to the extraction tank 1 at the same time due to the siphon effect existing in the U-shaped design process of the oil-water separator 3 can be overcome.
Referring to fig. 2, another embodiment of the present application provides a method for preparing natural perfume, comprising the steps of:
