Description

Technical Field

[0001] The invention relates to the technical field of plant essential oil extraction, in particular to plant essential oil extraction equipment and an extraction method for producing anti-aging cosmetics. Background Art

[0002] Essential oils are plant-specific aromatic substances extracted from flowers, leaves, roots, bark, fruits, seeds, resins, etc. of herbs by distillation and pressing. They are highly volatile, small in molecular weight, and easily absorbed. They can stimulate the secretion of the pituitary gland, enzymes, and hormones, balance the body's functions, and play a role in beauty and skin care. Essential oils are gradually becoming popular because of their pure natural extracts, which are completely taken from the essence of plants in nature and will not cause allergies. Especially functional essential oils, such as freckle essential oils, are healthier than drugs and safer than general freckle products, making them the first choice for freckle products. They can help people inhibit and delay the aging process of the skin, promote skin health, and improve the quality of life.

[0003] The method of essential oil extraction refers to the method of extracting essential oils from plants. Common essential oil extraction methods include steam distillation, freeze compression, chemical solvent extraction, oil separation, carbon dioxide extraction, and immersion. Before extraction, the plant essence needs to be extracted to form a certain concentration of extracted essential oil crude liquid, and then the essential oil pure liquid is extracted through extraction. In the process of extracting the plant essential oil crude liquid, some plants are difficult to mix with the extract (such as water), and it is difficult to precipitate the plant essential oil crude liquid. Even if the other part of the plants are mixed with the extract, the plant fiber has a tension effect on the liquid, making it difficult to separate the essential oil crude liquid around the plant. After part of the essential oil crude liquid is separated from the plant, it floats above the extract, and the essential oil crude liquid cannot be collected in time, so it will mix with the plant again and adsorb around the plant fiber, which greatly reduces the extraction of the essential oil crude liquid. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a plant essential oil extraction device, which is equipped with a movable pressing table that moves downward to squeeze out the extracting substance in the plant raw material; when the movable pressing table moves downward, part of the extracting liquid is injected into the injection channel at the bottom of the suction pressing component, so that it returns to the extraction tank again, forming the advantages of a circulating extraction effect, etc., which solves the problem that in the process of extracting the crude plant essential oil liquid, a part of the plants are difficult to mix with the extracting liquid (such as water), and thus it is difficult to precipitate the crude plant essential oil liquid; even if the other part of the plants are mixed with the extracting liquid, the crude essential oil liquid around the plants is difficult to separate due to the tension effect of the plant fibers on the liquid; and after part of the crude essential oil liquid is separated from the plants, it floats above the extracting liquid, and the crude essential oil liquid cannot be collected in time, so that it will be mixed with the plants again and adsorbed around the plant fibers, which greatly reduces the problem of extracting the crude essential oil liquid.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a plant essential oil extraction device having the following

[0019] Beneficial effects:

[0020] 1. The plant essential oil extraction equipment is driven downward by a linkage component, and the regulating cylinder moves downward so that the feed port at its bottom is merged with the twisting and kneading chamber, and the baffle is located above the twisting and kneading chamber. At this time, the twisting and kneading chamber is in a closed state, and the floating twisting and kneading component is used to twist and knead the floating plant raw materials so that the plant essential oil inside can be better extracted; at the same time, the movable pressing table drives the closed ring and the suction channel to move downward. During the downward movement of the suction channel, the plant raw materials and the extract in the inner cavity of the extraction tank flow into the suction pressing component through the suction channel together, and the movable pressing table is moved downward to squeeze out the extract in the plant raw materials; when the movable pressing table moves downward, part of the extract is injected into the injection channel at the bottom of the suction pressing component, so that it returns to the extraction tank again, forming a circulating extraction effect.

[0021] 2. The plant essential oil extraction equipment squeezes the sucked plant material by combining the passive pressing table in the suction pressing assembly with the movable pressing table, so that the extract inside is squeezed out, thereby allowing the essential oil components in the plant material to enter the extract. During the movement of the movable pressing table, due to the elastic connection between the passive pressing table and the movable pressing table, in the initial stage of the movement of the movable pressing table, the passive pressing table does not move, and when the movable pressing table moves downward, it can move relatively away from the passive pressing table to increase the space between the two, thereby being able to suck in the extract and plant material in the extraction tank.

[0022] 3. The plant essential oil extraction equipment, through the threaded grooves arranged in the through-holes, cooperates with the protrusions arranged on the sides of the twisting and kneading rods. When the downward-pressing twisting and kneading table drives the twisting and kneading rods to move, the protrusions on the twisting and kneading rods move in the threaded grooves. Since the fixed twisting and kneading table is in a fixed state, that is, the threaded grooves located in the through-holes are also in a fixed state, and then when the protrusions move in the threaded grooves, the downward-pressing twisting and kneading table can rotate at the same time, that is, the downward-pressing twisting and kneading table moves downward, and the downward-pressing twisting and kneading table moves toward the fixed twisting and kneading table. At the same time, the downward-pressing twisting and kneading table rotates relative to the fixed twisting and kneading table, and then the plant raw materials between the two can be twisted, so that the plant raw materials can be better mixed with the extract. The invention relates to a method for producing a plurality of extraction tanks, wherein when the twisting and kneading rod moves upward, the protrusion leaves the thread groove, and the downward pressing and kneading table moves upward, so that a cavity is formed between the downward pressing and kneading table and the fixed twisting and kneading table, and the plant material, extracted essential oil and extract above the extraction tank flow into the cavity, and when the downward pressing and kneading table moves downward, the protrusion can enter the thread groove along the V-shaped groove, so as to avoid the protrusion being misaligned with the thread groove after leaving the thread groove and being unable to enter the thread groove again; wherein a discharge port is provided on the side wall of the twisting and kneading cavity, above the fixed twisting and kneading table, and the discharge port is used for the plant material to be returned to the extraction tank after the downward pressing and kneading table and the fixed twisting and kneading table have twisted and kneaded the plant material.

[0023] 4. The plant essential oil extraction equipment, through the pressing chamber in the suction pressing component, when the movable pressing table moves upward, there is friction between the rubber sheet and the pressing chamber, and the rubber sheet flips down, and when the movable pressing table moves downward, there is friction between the rubber sheet and the pressing chamber, and the rubber sheet can be completely attached to the bottom of the movable pressing table, blocking the filter holes on the movable pressing table, so that a syringe structure is formed between the rubber sheet, the movable pressing table and the pressing chamber, and the extract flowing at the bottom of the pressing chamber is injected into the injection channel to form an extract circulation.

[0047] The thread groove 262 provided in the through hole 261 cooperates with the protrusion 411 provided on the side of the twisting and kneading rod 41. When the pressing twisting and kneading platform 25 drives the twisting and kneading rod 41 to move, the protrusion 411 on the twisting and kneading rod 41 moves in the thread groove 262. Since the fixed twisting and kneading platform 26 is in a fixed state, that is, the thread groove 262 located in the through hole 261 is also in a fixed state, and then when the protrusion 411 moves in the thread groove 262, the pressing twisting and kneading platform 25 can rotate while moving, that is, the pressing twisting and kneading platform 25 moves downward, and the pressing twisting and kneading platform 25 moves toward the fixed twisting and kneading platform 26. At the same time, the pressing twisting and kneading platform 25 rotates relative to the fixed twisting and kneading platform 26, so that the plant material between the two can be twisted, so that the plant material can be better mixed with the extract. When the rod 41 moves upward, after the protrusion 411 leaves the thread groove 262, the pressing and kneading platform 25 moves upward, so that a cavity is formed between the pressing and kneading platform 25 and the fixed kneading platform 26, and the plant material, extracted essential oil and extract above the extraction tank 1 flow into the cavity. When the pressing and kneading platform 25 moves downward, the protrusion 411 can enter the thread groove 262 along the V-shaped groove 263, so as to avoid the protrusion 411 from being misaligned with the thread groove 262 after leaving the thread groove 262 and being unable to enter the thread groove 262 again; wherein a discharge port 29 is provided on the side wall of the twisting and kneading cavity 24, above the fixed kneading platform 26, and the discharge port 29 is used for the pressing and kneading platform 25 and the fixed kneading platform 26 to knead the plant material, so that the plant material can return to the extraction tank 1 after the plant material is twisted and kneaded by the fixed kneading platform 26;

[0048] At the same time, driven by the linkage component 4, the movable pressing table 33 in the suction and pressing component 3 moves up following the regulating cylinder 21, and the suction channel 31 in the suction and pressing component 3 moves up synchronously driven by the closed ring 32, and the suction channel 31 is connected with the inner cavity of the extraction tank 1; the passive pressing table 34 in the suction and pressing component 3 cooperates with the movable pressing table 33 to press the sucked plant material, so that the extract inside is pressed out, so that the essential oil components in the plant material can enter the extract. In the process of the movement of the movable pressing table 33, due to the elastic connection between the passive pressing table 34 and the movable pressing table 33, in the initial stage of the movement of the movable pressing table 33, the passive pressing table 34 does not move, and when the movable pressing table 33 moves downward, it can be relatively away from the passive pressing table 34 to enlarge the space between the two, so that the extract and plant material in the extraction tank 1 can be sucked in;

[0049] Then, the linkage component 4 is driven downward to adjust the cylinder 21 to move downward, so that the feed port 22 at the bottom thereof is merged with the twisting and kneading chamber 24, and the baffle 23 is located above the twisting and kneading chamber 24. At this time, the twisting and kneading chamber 24 is in a closed state, and the floating twisting and kneading component 2 is used to twist and knead the floating plant raw materials so that the plant essential oil inside can be better extracted; at the same time, the movable pressing table 33 drives the closed ring 32 and the suction channel 31 to move downward as well. During the downward movement of the suction channel 31, the plant raw materials and the extract in the inner cavity of the extraction tank 1 flow into the suction pressing component 3 through the suction channel 31, which is beneficial to the extraction of the essential oil. The movable pressing table 33 is moved downward to squeeze out the extract in the plant raw material; the twisting and kneading rod 41 and the pressing rod 42 are connected by rotation, so that there is only an up-and-down drive between the twisting and kneading rod 41 and the pressing rod 42, and the passive pressing table 34 with the mounting groove 341 is used to make the passive pressing table 34 and the movable pressing table 33 in an elastic state; when the movable pressing table 33 moves downward, part of the extract is injected into the injection channel 5 at the bottom of the suction and pressing component 3, so that it returns to the extraction tank again, forming a circulating extraction effect;

[0050] The filter holes 331 on the movable pressing table 33 can squeeze out the extract in the plant material between the movable pressing table 33 and inject it into the injection channel 5 through the filter holes 331 when the movable pressing table 33 moves toward the passive pressing table 34. When the movable pressing table 33 moves upward, the rubber sheet 35 is separated from the movable pressing table 33, so that the filter holes 331 can squeeze out the extract in the plant material and flow downward. The pressing chamber 36 in the suction pressing assembly 3 is sucked into the pressing chamber 36 when the movable pressing table 33 moves upward. When the movable pressing table 33 moves upward, there is friction between the rubber sheet 35 and the pressing chamber 36, and the rubber sheet 35 turns downward. When the movable pressing table 33 moves downward, there is friction between the rubber sheet 35 and the pressing chamber 36. The rubber sheet 35 can completely fit on the bottom of the movable pressing table 33, blocking the filter holes 331 on the movable pressing table 33, so that an injector structure is formed between the rubber sheet 35, the movable pressing table 33 and the pressing chamber 36, and the extract flowing at the bottom of the pressing chamber 36 is injected into the injection channel 5.
