AI Technical Summary
Existing plant fiber extraction methods have slow dissolution rates, low cellulose purity, and low extraction efficiency, mainly because cellulose is tightly bound to lignin and hemicellulose, making it difficult to separate them completely.
The ginger family herbaceous plants are pressed using a double-drum press, combined with ultrasonic treatment using dilute hydrochloric acid and silica, and then steamed with an alkaline solution under high temperature and pressure. This process breaks down the cell wall structure, improves dissolution efficiency, and increases cellulose purity.
By disrupting the cell wall structure, the extraction efficiency and purity of cellulose were improved, and the residues of lignin and hemicellulose were reduced, thus achieving highly efficient cellulose extraction.

Abstract
Description
Technical Field
[0001] The invention relates to the technical field of plant fiber extraction, in particular to a natural ginger herb fiber extraction process and production equipment thereof. Background Art
[0002] Plant fiber is a thick-walled tissue found widely in seed plants. Its cells are elongated, pointed at both ends, and have thick secondary walls that often contain simple pits. At maturity, they generally lack living protoplasts. Plant fiber is a filamentous or flocculent substance formed by the combination of cellulose and various nutrients. It supports, connects, wraps, and fills plants, and is widely found in plant stems, roots, fruits, and shells, such as those found in natural ginger plants.
[0003] Most of the plant fiber extraction methods in the prior art use slurry to directly soak and dissolve plant cell walls, that is, to dissolve lignin and hemicellulose to obtain cellulose. However, the cell walls composed of dense fibers are relatively strong, and direct dissolution with alkaline solution has a slow dissolution rate, which affects the extraction efficiency. In addition, the dissolution is insufficient, resulting in the extracted cellulose containing more lignin and hemicellulose, which reduces the purity of the extracted cellulose.

In addition, the high-pressure environment is conducive to breaking the cell wall. The high-temperature and high-pressure environment is conducive to the full dissolution of lignin and hemicellulose by the alkali solution. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A natural ginger herb fiber extraction process comprises the following steps:
[0043] S1. Cutting the ginger herb into 30-50 mm long pieces, and removing dust, some leaves, and nodes from the pieces through a dust collector to obtain the herb raw material;

[0051] Specifically, the alkaline solution is sodium hydroxide or potassium hydroxide solution, and the concentration of the sodium hydroxide or potassium hydroxide solution is 1%-3%.
[0052] Specifically, the flushing liquid is distilled water or ethanol.
[0053] Please refer to Figure 1-10 As shown: The second technical solution provided by the present invention is:
[0054] A production device for natural ginger herb fiber includes a cooking device, which includes two symmetrically arranged mounting frames 1 and a cooking kettle 2 with an opening on the top. A lifting drive member 3 is installed on the mounting frames 1 along the height direction. A steam inlet pipe 4 and a steam exhaust pipe 5 are respectively connected to the opposite side walls of the cooking kettle 2, and the steam inlet pipe 4 and the steam exhaust pipe 5 are connected to an external steam generator. The cooking kettle 2 is located between the two mounting frames 1, and the steam inlet pipe 4 and the steam exhaust pipe 5 are respectively connected to the lifting drive member 3 on the same side. A cover plate 6 is provided between the tops of the two mounting frames 1, covering the opening of the cooking kettle 2. A drain pipe 7 is connected to the bottom of the cooking kettle 2, and one end of the drain pipe 7 extends into the interior of the cooking kettle 2. A plurality of filter holes 8 are provided on the outer wall of the end of the drain pipe 7 located inside the cooking kettle 2. A stirring mechanism 9 is rotatably connected to the top of the cover plate 6. One end of the stirring mechanism 9 passes through the cover plate 6 and is located in the inner cavity of the cooking kettle 2. The end of the stirring mechanism 9 located in the inner cavity of the cooking kettle 2 is connected to a blocking rod 10 that cooperates with the drain pipe 7. A feed pipe 11 is connected to the top of the cover plate 6.
[0055] When the cooking kettle 2 is cooking, the blocking rod 10 is inserted into the inner cavity of the drain pipe 7 and blocks the filter hole 8. When the cooking kettle 2 is filtering, the lifting drive member 3 drives the cooking kettle 2 to descend and separates the blocking rod 10 from the drain pipe 7.
[0056] From the above description, it can be seen that when the cooking device of the present invention cooks the mixed liquid, the cooking kettle can be heated and cooked by an external steam generator, and the mixed liquid can be stirred by a stirring mechanism during the cooking process, thereby improving the cooking efficiency. After the cooking is completed, the cooking kettle descends under the drive of the lifting drive member, so that the sealing rod is separated from the drain pipe, so that the residual liquid after cooking can be filtered through the drain pipe, and finally the cooking and filtering operations of the plant fiber are realized, that is, no other equipment is required to filter the plant fiber, and there is no need to repeatedly operate the plant fiber, which reduces the workers' operating procedures and improves efficiency.
[0057] Specifically, the cooking kettle 2 includes a kettle body 21 and an insulation sleeve 22, and the bottom of the kettle body 21 is an arc-shaped structure. The insulation sleeve 22 is arranged on the outer wall of the kettle body 21, and a gap is provided between the inner wall of the insulation sleeve 22 and the outer wall of the kettle body 21. The steam inlet pipe 4 and the steam exhaust pipe 5 are respectively connected to the insulation sleeve 22, and a plurality of heat-conducting strips 23 are provided at equal angles on the outer wall of the kettle body 21.
[0058] From the above description, it can be seen that wrapping the outer side of the kettle body with an insulation layer and injecting heating steam into the insulation layer to heat the kettle body can improve the heating effect of the kettle body, and the provision of heat-conducting strips on the outer wall of the kettle body can improve the heat exchange performance of the kettle body and further improve the heating effect.
[0059] Specifically, the lifting drive member 3 includes a screw 31 and a limit rod 32 arranged in parallel. The mounting frame 1 is provided with a mounting groove along the height direction. The screw 31 and the limit rod 32 are installed between the top and bottom of the inner cavity of the mounting groove. A first motor 33 is installed on the top of the mounting frame 1, and the first motor 33 is connected to the screw 31. The outer wall of the screw 31 is threadedly connected to a slider 34, and the slider 34 is slidably connected to the limit rod 32.
[0060] Specifically, the stirring mechanism 9 includes a rotating rod 91 and a rotating drive member 92. The bottom of the rotating rod 91 is connected to the sealing rod 10. A connecting rod 93 is fixed to the outer wall of the rotating rod 91. The free end of the connecting rod 93 is connected to a stirring rod 94 that is adapted to the inner wall of the cooking kettle 2, and the stirring rod 94 is respectively abutted against the inner cavity side wall, bottom and outer wall of the drain pipe 7 of the cooking kettle 2. The rotating drive member 92 is installed on the top of the cover plate 4. One end of the rotating rod 91 passes through the cover plate 4 and is connected to the rotating drive member 92.
[0061] From the above description, it can be seen that the rotating rod and the stirring rod are driven to rotate by the rotating driving member, so that the residual liquid in the cooking kettle can be stirred by the stirring rod, thereby increasing the heat exchange rate between the residual liquid and the cooking kettle and improving the cooking effect, and the stirring rod is in contact with the inner cavity side wall, bottom and outer wall of the discharge pipe of the cooking kettle, so that the bottom of the cooking kettle can be cleaned during stirring to avoid residue accumulation at the bottom of the cooking kettle, and the side wall of the discharge pipe can also be cleaned at the same time, so that the filter hole can be cleaned during filtration to avoid clogging.
[0062] Specifically, the inner cavity of the free end of the connecting rod 93 is provided with a sliding cavity, and the inner cavity of the sliding cavity is slidably connected to a sliding block 95. A spring 96 is provided between the sliding block 95 and the end of the inner cavity of the sliding cavity. A mounting rod 97 is fixedly connected to the side of the sliding block 95 away from the spring 96, and the mounting rod 97 is connected to the stirring rod 94.
[0063] From the above description, it can be seen that the stirring rod and the connecting rod are connected by a spring and a mounting rod, so that when the cooking kettle is lowered to a certain height for filtering, the stirring rod can always remain in contact with the inner wall of the cooking kettle under the action of the spring restoring force, so that the stirring rod can always stir the bottom of the cooking kettle.
[0064] Specifically, the interiors of the rotating rod 91 and the connecting rod 93 are both hollow structures, and a block is provided between the hollow part of the connecting rod 93 and the sliding cavity. The connecting rod 93 and the rotating rod 91 are connected to each other. An opening is provided at the top of the rotating rod 91. The top of the rotating rod 91 is sealed with an end cover 12 through a rotating flange. The end cover 12 is respectively connected to the liquid inlet pipe 13 and the drying pipe 14. A number of air injection holes 15 are provided at the bottom of the connecting rod 93.
[0065] From the above description, it can be seen that after the filtration is completed, the rinsing liquid for rinsing the filter residue and the drying gas for drying the filter residue can be injected into the cooking kettle through the liquid inlet pipe respectively, so that the plant fiber can be formed in one cooking kettle without the need for using multiple sets of equipment for processing. In addition, during the rinsing and drying process, the rinsing liquid / drying gas can be sprayed toward the filter residue through the air jet hole at the bottom of the connecting rod, achieving the effect of rinsing / drying while rotating, thereby improving efficiency.
[0066] Specifically, the steam inlet pipe 4 and the steam exhaust pipe 5 are rotatably connected to the lifting drive member 3, and the steam inlet pipe 4 and the steam exhaust pipe 5 are rotatably connected to the external steam generator. The outer walls of the steam inlet pipe 4 and the steam exhaust pipe 5 are fixed with a rotating gear 16, and the side wall of the mounting frame 1 is provided with a rack 17 that cooperates with the rotating gear 16. When the cooking kettle 2 descends, the rotating gear 16 meshes with the rack 17 and drives the cooking kettle 2 to flip 180 degrees.
[0067] From the above description, it can be seen that after the cooking is completed, the cooking kettle can be lowered by the lifting drive member, and after it is lowered to a certain height, the cooking kettle is turned 180 degrees by rotating the gear and the rack, so that the opening of the cooking kettle is turned downward, thereby facilitating the discharge of the cooked plant fiber.

[0089] Then, the external steam generator is started and the generated steam is input into the gap between the insulation jacket 22 and the kettle body 21 through the steam inlet pipe 4, thereby heating the outer wall of the kettle body 21 through the steam, thereby achieving the cooking of the internal mixed liquid B. In addition, the heat conductive strips 23 on the outer side of the kettle body 21 can improve the thermal conductivity of the kettle body 21. During the cooking process, an end cap with a vent hole is provided at the opening of the liquid inlet pipe 13, so that the cooking gas generated during the cooking process can be discharged through the liquid inlet pipe 13 without causing heat loss in the kettle body 21.
[0090] During the cooking process, the second motor 921 of the rotary drive member 92 is started, and the second motor 921 drives the incomplete active bevel gear 922 to rotate. The incomplete active bevel gear 922 first meshes with the driven bevel gear 923 located above, thereby driving the rotating rod 91 and the stirring rod 93 to rotate forward, stirring the mixed liquid in the kettle body 21, so that the mixed liquid can be evenly heated and the cooking effect is improved. The incomplete active bevel gear 922 continues to rotate, meshing with the driven bevel gear 923 located below, thereby driving the rotating rod 91 to rotate in the opposite direction, and so on and so forth to achieve the stirring rod 94 to stir the mixed liquid in a forward and reverse reciprocating manner, thereby avoiding the inertia of the internal mixed liquid caused by a single stirring direction;
[0091] After the steaming is completed, the first motors 33 on both sides are started (the first motors 33 on both sides are synchronous, bidirectional motors). The rotation of the first motors 33 drives the screw 31 to rotate, thereby driving the slider 34, the steam inlet pipe 4 and the steam outlet pipe 5 to slide downward (one end of the steam inlet pipe 4 and the steam outlet pipe 5 is a retractable hose structure), thereby driving the kettle body 21 to slide downward, so that the kettle body 21 and the cover plate 6 slide relative to each other, so that the drain pipe 7 slides out from the blocking rod 10, and then the filter hole 8 of the drain pipe 7 is opened, so that the second residual liquid after cooking is filtered and discharged. During the filtering, the bottom of the blocking rod 10 is located above the drain pipe 7 and blocks the opening to prevent the residual liquid from flowing out of the opening;
[0092] When the kettle body 21 descends to the filtering position, the mounting rod 97 at the end of the connecting rod 93 always drives the stirring rod 94 to abut against the inner wall of the kettle body 21 under the action of the restoring force of the spring 96. During the filtering process, the second motor 921 continues to work to stir the second residual liquid and clean the outer wall of the drain pipe 7 to prevent the filter hole 8 from being blocked.
[0093] After filtration is completed, the flushing liquid inlet pipe 13 is opened, and the flushing liquid 13 is injected into the rotating rod 91 and flows into the connecting rod 93, and then sprayed out from the air jet hole 15, thereby flushing the filtered residue and discharging it through the drain pipe 7. Similarly, during the flushing process, the stirring rod 94 is always rotating to stir the residue;
[0094] After the rinsing is completed, the liquid inlet pipe 13 is closed and the drying pipe 14 is opened to inject the drying gas into the rotating rod 91 and spray it out from the air jet hole 15 to jet-dry the residue, and then discharge it from the liquid discharge pipe 7. Similarly, during the drying process, the stirring rod 94 always rotates to stir the residue.
[0095] After the drying is completed, the two groups of first motors 33 are started again, and the first motor 33 drives the kettle body 21 to continue to descend, so that the stirring rod 94 and the blocking rod 10 are separated from the kettle body 21. At this time, since the height of the drain pipe 7 extends inside the kettle body 21, that is, the height of the drain pipe 7 is higher than the height of the bottom of the inner cavity of the kettle body 21, the plant fiber can be prevented from falling out of the drain pipe 7; the kettle body 21 continues to descend so that the rotating gear 16 is engaged with the rack 17, thereby driving the rotating gear 16 and the steam inlet pipe 4 and the steam outlet pipe 5 to rotate, so that the kettle body 21 is flipped 180 degrees and the opening is set downward, so as to facilitate the staff to discharge the plant fiber in the kettle body 21, thereby realizing rapid discharging. After the discharging is completed, the first motor 33 is rotated in the opposite direction to raise the kettle body 21 to the steaming position again.
