[0002] Dendrobium is a perennial herb belonging to the genus Dendrobium in the family Orchidaceae. It has a sweet taste and slightly cold nature, and is a precious Chinese medicine with a wide range of medicinal uses. It has the effects of benefiting the stomach and promoting the production of body fluids, nourishing yin and clearing heat. It can be used to treat symptoms such as heat-related illnesses with fluid depletion, dry mouth and thirst, stomach yin deficiency, poor appetite and dry retching, persistent low fever after illness, yin deficiency and fire excess, bone steaming fever, blurred vision, and weakness of muscles and bones. In order to increase the concentration of active ingredients, a concentration extraction device is used to extract the active ingredients.

[0003] Currently, when extracting Dendrobium, the Dendrobium is crushed and piled inside the extraction tank, and then extracted by water decoction or alcohol extraction. However, both of these methods have the problem that a lot of effective components remain in the raw material after extraction, requiring staff to take out the raw material and squeeze it again for extraction, which makes the extraction process more complicated and reduces the overall concentration and extraction efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a whole-plant compound extraction and concentration device for Dendrobium to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Dendrobium whole plant compound extraction and concentration device, comprising: an extraction barrel and a barrel lid, further comprising: a squeezing plate, installed inside the extraction barrel and configured to move up and down along the height of the extraction barrel, with the whole Dendrobium plant placed on the squeezing plate; a water injection device, installed above the barrel lid, for injecting hot water into the extraction barrel through the barrel lid; a baffle, fixedly installed on the extraction barrel or barrel lid and located above the Dendrobium, so that when the squeezing plate and the Dendrobium move upward, they cooperate with the baffle to squeeze the Dendrobium; multiple through holes, formed on the squeezing plate, so that the squeezed Dendrobium effective substance liquid flows from the through holes to the bottom of the extraction barrel; and multiple shower holes, formed on the baffle, with the hot water injected by the water injection device falling evenly onto the whole Dendrobium plant through the shower holes.

[0006] Preferably, it further includes: a filter screen plate, fixedly disposed inside the extrusion plate; a plurality of locking blocks, fixedly disposed on the inner surface of the extrusion plate, the locking blocks being located at the lower edge; and a clearance groove formed on the surface of the filter screen plate. When the locking blocks and the clearance groove are aligned, the filter screen plate can enter the interior of the extrusion plate. When the locking blocks and the clearance groove are misaligned, the filter screen plate is blocked.

[0007] Preferably, it further includes: a sealing ring, which is fixedly disposed inside the extrusion plate, wherein when the filter screen is fixed to the extrusion plate, the surface of the sealing ring is in close contact with the surface of the filter screen.

During the movement, the material between the two is squeezed by the cooperation with the baffle, so that the effective components in the material are squeezed out. Then, the extruded effective components are flushed to the bottom of the extraction barrel by the water injection device for collection, thus realizing the one-time extraction of the effective components in the material and improving the extraction efficiency of the effective components. Furthermore, by moving the extrusion plate from bottom to top, the material can be transported to the top of the extraction barrel, which is convenient for the extracted material to be discharged.

[0013] (2) By setting up a filter screen, this utility model can filter the mixed solution after squeezing, thereby improving the purity of the extract.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] This utility model provides the following technical solution: Referring to 1-4, in this embodiment, a Dendrobium whole plant composite extraction and concentration device includes: an extraction barrel 1 and a barrel cover 2, and also includes: an extrusion plate 4, installed inside the extraction barrel 1, configured to move up and down along the height of the extraction barrel 1. The whole Dendrobium plant is placed on the extrusion plate 4. The extrusion plate 4 is made of a hard material, which can ensure that the extrusion plate 4 is not easily deformed during the extrusion of the whole Dendrobium plant. It can be made of high-speed steel or high-carbon steel. High-speed steel has high hardness and wear resistance, and can maintain shape stability when subjected to large extrusion pressure; high-carbon steel, after quenching treatment, can also meet the hardness requirements, and the cost is relatively low, making it suitable for mass production. Water injection device 17 is installed above the lid 2 and is used to inject hot water into the extraction bucket 1 through the lid 2. Water injection device 17 mainly consists of a ring pipe and a water injection pipe, and the water injection pipe is connected to the inside of the lid 2. Baffle 16 is fixedly installed on the extraction bucket 1 or lid 2 and is located above the Dendrobium. Baffle 16 is made of a hard material, specifically carbon steel, so that when the extrusion plate 4 and the Dendrobium move upward, they cooperate with the baffle 16 to extrude the Dendrobium. At the same time, the baffle 16 can also intercept the whole Dendrobium plant to prevent the raw material from clogging the water injection device 17 during the extrusion process. Multiple through holes 6 are provided on the extrusion plate 4 so that the liquid containing the effective substance of Dendrobium obtained by extrusion flows from the through holes 6 to the bottom of the extraction bucket 1; multiple shower holes 5 are provided on the baffle 16, and the hot water injected by the water injection device 17 falls evenly on the whole Dendrobium plant through the shower holes 5.

[0018] The material can be lifted by the extrusion plate 4 and squeezed by the baffle 16. The extrusion hole 6 allows the squeezed juice to flow with the hot water and fall into the bottom of the extraction tank 1 for storage.

[0019] It also includes: a filter screen plate 8, which is fixedly installed inside the extrusion plate 4, and the diameter of the filter holes of the filter screen plate 8 is smaller than the diameter of the through hole 6; several locking blocks 7, which are fixedly installed on the inner surface of the extrusion plate 4 and can be fixedly connected to the extrusion plate 4 by welding or plugging, and the locking blocks 7 are located at the lower edge; and a clearance groove 9, which is opened on the surface of the filter screen plate 8. The clearance groove 9 can be opened by integral molding or stamping. When the locking blocks 7 and the clearance groove 9 are aligned, the filter screen plate 8 can enter the interior of the extrusion plate 4. When the locking blocks 7 and the clearance groove 9 are misaligned, the filter screen plate 8 is blocked.

[0020] The filter screen 8 can filter the flowing mixture and remove impurities such as fibers, ensuring the quality of the concentrated solution. The locking block 7 and the clearance groove 9 can limit the position of the filter screen 8 and facilitate disassembly, making it easier to clean.

[0021] It also includes: a sealing ring 10, which is fixedly installed inside the extrusion plate 4. The sealing ring 10 is made of highly elastic rubber, which can be made of ethylene propylene diene monomer (EPDM) rubber. It has excellent weather resistance, ozone resistance and aging resistance, and can be used for a long time in outdoor or high temperature environments (-40℃~150℃). When the filter screen plate 8 is fixed to the extrusion plate 4, the surface of the sealing ring 10 is in close contact with the surface of the filter screen plate 8. In this case, the sealing ring 10 will generate a reaction force on the filter screen plate 8 due to its deformation, so that the filter screen plate 8 and the locking block 7 fit more tightly, which enhances the sealing of the connection and prevents unfiltered liquid from flowing out from the gap.

[0022] It also includes: several positioning grooves 11, which are formed on the inner surface of the extraction barrel 1; several positioning blocks 12, which are fixedly set on the outer surface of the extrusion plate 4 and can be connected and fixed by welding. The outer surface of the positioning block 12 is slidably set with the inner surface of the positioning groove 11, and the extrusion plate 4 can be positioned by matching the positioning groove 11 and the positioning block 12 to prevent it from rotating with the adjusting screw 3.

[0023] It also includes: a placement groove 15, which is opened at the top of the extraction barrel 1 and can be integrally molded onto the extraction barrel 1; the barrel cover 2 is configured such that when installed, the baffle 16 is located inside the placement groove 15; and the barrel cover 2 and the extraction barrel 1 are threaded together.

[0024] It also includes: adjusting screw 3, which is rotatably set on the bottom surface inside the extraction barrel 1, with the adjusting screw 3 located at the center position; The drive motor 13 is a forward and reverse motor, which is fixedly installed at the bottom of the extraction barrel 1. It can be fixed to the extraction barrel 1 by bolts. The output end of the drive motor 13 is connected to the bottom end of the adjusting screw 3 by a coupling. When the drive motor 13 is started, it can drive the adjusting screw 3 to rotate forward or reverse, thereby realizing the precise adjustment of the position of the extrusion plate 4, meeting different extrusion requirements, and achieving the adjustment effect of the position of the extrusion plate 4.

[0025] It also includes: a discharge pipe 18, which is connected to the extraction tank 1, and a control valve 19 is provided on the discharge pipe 18. The control valve 19 is a ball valve, which can close or open the discharge pipe 18. The flow guide seat 14 is fixedly installed on the bottom surface inside the extraction tank 1. The flow guide seat 14 is truncated cone-shaped and can push the mixture to all sides for easy discharge. The outer surface of the adjusting screw 3 is rotated with the inside of the flow guide seat 14.

[0026] This utility model provides a whole-plant compound extraction and concentration device for Dendrobium, the specific working principle of which is as follows: During the extraction and concentration of Dendrobium officinale whole plant, the staff first pours the crushed Dendrobium officinale whole plant into the extraction tank 1, allowing it to fall onto the extrusion plate 4. Then, the baffle 16 and the tank lid 2 are installed in sequence. After installation, the staff starts the drive motor 13 and injects hot water into the water injection device 17. As the hot water flows through the Dendrobium officinale whole plant, it breaks down the cell structure, allowing the effective components inside to flow into the bottom of the extraction tank 1 along with the hot water. Simultaneously, the drive motor 13 slowly rotates the adjusting screw 3, causing the extrusion plate 4 to move upwards within the extraction tank 1 under the influence of the adjusting screw 3. During this movement, the extrusion plate 4, in conjunction with the baffle 16, extrudes the Dendrobium officinale... The entire plant is squeezed, which breaks down the cells of the Dendrobium plant more quickly and also causes the absorbed liquid to be expelled. The expelled liquid is then stored at the bottom of the extraction tank 1 under the action of hot water. As the liquid flows, it passes through the filter plate 8, which isolates fibrous impurities in the liquid, improving its purity and subsequent concentration quality. When the filter plate 8 needs to be cleaned, the operator rotates it so that the clearance groove 9 aligns with the locking block 7, releasing the restriction on the filter plate 8 so that it can be removed for cleaning.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
