Problems solved by technology

However, it was later confirmed that this process is not suitable for some plants. Although the process of high temperature and high pressure can break the cell wall and be extracted, it will also cause the decomposition of typical substances in the cell fluid, resulting in the content of some target compounds. Very low, or even completely decomposed, for this reason, improvement is needed

Embodiment 1

[0031] The present invention prepares cell fluid through the following steps: S1) soaking at room temperature for 3 to 5 hours until the dried extract is swollen and saturated with water; 120°C~190°C, absolute pressure 130KPa~320KPa, to break the plant cell wall and vaporize the cell fluid;

[0032] S2) Separation of heavy metals and drug residues under high temperature and negative pressure: Cool the top part of the container by air cooling or water cooling to keep the internal pressure of the container at the ultimate vacuum of 40KPa~60KPa, and control the internal temperature of the container to 120°C~190°C. The liquid forms droplets on the top wall of the container and is separated from carbon-containing heavy metal impurities and drug residues, and the separated waste liquid is collected and discharged through the waste liquid tank;

[0033] S3) Extraction of high-temperature negative pressure cell fluid: start the vacuum pump to reduce the pressure of the container to th...

Embodiment 2

[0041] see figure 2 , this embodiment is further improved on the basis of Embodiment 1, specifically, the bottom wall 7 of the cover body includes a central area and an outer ring area, the outer ring area arches downward toward the central area, and the central area Then the upward arc is arched to form an arched circle structure, and the contour line connecting the outer ring area and the central area is positively projected in the container. This structure can also make the cell fluid attached to the surface of the bottom wall slide to the outside along the arc surface. The junction of the ring area and the center area, then drips into the container. The rest of the structure of this embodiment is the same as that of Embodiment 1.

Embodiment 3

[0043] see image 3 , this embodiment is further improved on the basis of Embodiment 2, specifically, the cooling fan 18 is placed outside, the air inlet and outlet of the cooling air chamber 11 are respectively opened on the side wall of the cover body, and the air inlet of the cooling air chamber passes through The external air duct 6 is connected to the air outlet of the cooling fan 18 . The rest of the structure of this embodiment is the same as that of the second embodiment.

Abstract

The invention discloses a plant cell sap extraction method and device, and the extraction method comprises the following steps: S1) taking fresh plant fragments or a to-be-extracted product saturated by water absorption, and carrying out high-temperature and high-pressure heating in a closed container at a heating temperature of 120-190 DEG C and an absolute pressure of 130-320 KPa so as to break the wall of plant cells and vaporize the cell sap; s2) high-temperature negative-pressure heavy metal and drug residue separation; s3) starting a vacuum pump to reduce the pressure of the container, and controlling the temperature in the container to be 110-180 DEG C, so that the cell sap is continuously evaporated and separated in the container, and liquid drops are formed at the top and fall into a containing cup in the container; and S4) reducing the pressure of the container to 100-1000 Pa, and controlling the internal temperature of the container to 105-175 DEG C, so that the cell sap is stably purified and forms the small molecular group cell sap. According to the method disclosed by the invention, the drug residue separation and the small molecular group extraction are completed in the negative pressure environment, and the decomposition of typical substances in the cell sap is reduced under the negative pressure condition, so that the extracting solution keeps the original character characteristics as much as possible.

Description

technical field [0001] The invention relates to the technical field of cell fluid extraction, and more specifically relates to a plant cell fluid extraction device and method. Background technique [0002] The liquid in the vacuoles of plant cells is called cell fluid, in which inorganic salts, amino acids, sugars, various pigments, etc. are dissolved. Plant cell extracts have high economic value or medicinal value. For example, selecting appropriate Chinese herbal medicine to extract its The cell liquid can avoid the process of decocting medicine. After the cell liquid is extracted, the plant residue is separated from the cell liquid with medicinal effects, which is convenient to take and has a good absorption effect. The applicant in this case submitted a Chinese invention application for a plant cell sap extraction device and process earlier, the application number is 2020100826303, which discloses the method of breaking the wall of plant cells by heating at high temperat...
