Description

Technical Field

[0001] This invention relates to an extraction apparatus, and more particularly to a plant polysaccharide extraction apparatus. Background Technology

[0002] Plant polysaccharides are polymers composed of many identical or different monosaccharides linked by α- or β-glycosidic bonds, mainly including starch, cellulose, fructans, and pectin. Like proteins, polysaccharides possess complex structures as biological macromolecules and exhibit certain physiological and biological activities. Extraction requires hot water immersion, utilizing the property that polysaccharides are readily soluble in water but insoluble in high-concentration ethanol for extraction and precipitation. This method is simple to operate, low in cost, and is one of the most commonly used techniques in laboratory and industrial production.

[0003] For example, a plant polysaccharide extraction device, disclosed in Chinese Patent Publication No. CN217854894U, belongs to the field of plant polysaccharide extraction technology. It includes a housing movably connected to a base frame. A vertical plate is fixedly connected to the front and rear sides of the base frame. Semi-circular worm gears are fixedly connected to the front and rear sides of the bottom of the housing. An axle is movably connected to the two worm gears, passing through the vertical plates on both sides and fixedly connected to them. The two worm gears are respectively engaged with worms below them. A driving pulley and a driven pulley are fixedly connected to one end of each worm. The driving pulley is connected to the driven pulley via a belt. The worm on the driving pulley is connected to a motor. The two worms are driven to rotate simultaneously by a belt drive, which in turn drives the worm gears to move the housing. The worm gears rotate on the axle, causing the housing to tilt and rotate to the desired angle under the support of the axle. This invention allows the filtered liquid to be completely and smoothly discharged from the housing without residue. However, this patent has the following problems: First, the precipitation of polysaccharides from the raw material takes a certain amount of time. Since it is not equipped with any heating or ultrasonic devices, the soaking time required for the raw material is greatly increased, resulting in a slow extraction efficiency. Secondly, when the raw material is soaked and precipitates polysaccharides, it will absorb a large amount of leachate. If the raw material is discharged directly, the absorbed leachate will be discharged along with it, resulting in a waste of leachate and polysaccharides. Summary of the Invention

[0004] The purpose of this invention is to provide a plant polysaccharide extraction device to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plant polysaccharide extraction device, comprising an extractor, wherein the extractor has an extraction pool, and further comprising: The slag discharge conveyor belt is installed in the installation groove at the bottom of the extraction tank and extends to the rear end of the extractor. The stirring mechanism includes a power motor and several stirring rods. A motor bracket is fixedly connected to the inner wall of the extraction tank. The power motor is fixedly mounted on the power motor. A transmission shaft is fixedly connected to the output end of the power motor.

[0016] 2. The leached raw material is transported to the collection box by the slag discharge conveyor belt. During the conveying process, the liquid inside the conveyed raw material can be squeezed out to ensure that the leachate is not mixed with the raw material residue and discharged together.

[0017] 3. The leachate can be filtered using a filter screen to prevent raw material residue from being mixed with the leachate and discharged together. The curved scraper is attached to the bottom of the extraction tank. When the curved scraper rotates, it will scrape off the raw material residue that has accumulated and blocked the filter screen, thus preventing the filter screen from being blocked by the accumulated raw material residue.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1-5 As shown, the present invention has the following specific embodiments.

[0022] Example 1 A plant polysaccharide extraction device includes an extractor 1, an extraction tank 101 formed on the extractor 1, and further includes: The bottom of the extraction tank 101 is provided with an installation groove for the slag discharge conveyor belt 2. The slag discharge conveyor belt 2 is installed in the installation groove and extends to the rear end of the extractor 1. The stirring mechanism includes a power motor 3 and several stirring rods 302. A motor bracket 106 is fixedly connected to the inner wall of the extraction tank 101. The power motor 3 is fixedly installed on the power motor 3. A transmission shaft 301 is fixedly connected to the output end of the power motor 3. Several stirring rods 302 are arrayed and fixedly installed on the outer wall of the transmission shaft 301. The roller pressing mechanism includes a mounting frame 4 and a slag pressing roller 401. The slag pressing roller 401 is rotatably installed inside the mounting frame 4. A support frame 107 is fixedly connected to the extractor 1. The support frame 107 has symmetrical sliding holes. A connecting slide rod 403 is symmetrically fixedly connected to the mounting frame 4. The connecting slide rod 403 is slidably installed in the sliding hole. A compression spring 404 is sleeved on the connecting slide rod 403. Collection box 5 is located behind extractor 1 and below the rear end of slag discharge conveyor belt 2. Collection box 5 is used to collect waste residue.

[0023] In this embodiment, the plant material is pre-treated by washing, drying, and crushing it into small pieces to increase the contact area. Then, selective defatting is performed. The treated raw material is then placed into the extraction tank 101, followed by the addition of a certain amount of medicinal solution. The power motor 3 is started, driving the drive shaft 301 to rotate. The rotation of the drive shaft 301 drives the stirring rod 302 to rotate, ensuring thorough mixing of the raw material and the medicinal solution, thereby effectively extracting the polysaccharides from the raw material. The heater 6 is then activated to heat the medicinal solution to 60-80°C, further leaching the polysaccharides from the raw material. Inside the liquid medicine, the slag discharge conveyor belt 2 is then activated, which will drive the raw material that has settled at the bottom. The slag discharge conveyor belt 2 is used to transport the precipitated raw material to the collection box 5. The compression spring 404 can provide a certain downward thrust to the mounting frame 4. The mounting frame 4 is pushed and will drive the slag pressure roller 401 to stick to the slag discharge conveyor belt 2. Then, the slag pressure roller 401 is used to press the raw material slag conveyed on the slag discharge conveyor belt 2, squeezing out the leachate inside the raw material slag, ensuring that the leachate is not mixed with the raw material slag and discharged together. At the same time, the stirring and heating of the liquid medicine effectively improves the polysaccharide extraction efficiency inside the raw material.

[0024] Example 2 The extractor 1 has a drain port 102 at the bottom. A filter screen 103 is fixedly connected to the drain port 102 near the upper edge. A discharge connecting pipe 104 is fixedly connected to the front of the extractor 1. The discharge connecting pipe 104 communicates with the inside of the drain port 102. A valve 105 is fixedly connected to the discharge connecting pipe 104. A T-shaped slot 108 is opened at the rear of the extractor 1. A T-shaped block 501 is fixedly connected to the front of the collection box 5. The T-shaped block 501 slides in cooperation with the T-shaped slot 108. A conveyor belt scraper 201 is fixedly connected to the rear of the extractor 1. The conveyor belt scraper 201 cooperates with the slag discharge conveyor belt 2.

[0025] In this embodiment, the leachate can be discharged from the device by connecting the discharge pipe 104 to the inside of the discharge port 102. The leachate can be filtered by the filter screen 103 to prevent the raw material residue from mixing inside the leachate. The valve 105 can be used to manually close or open the discharge pipe 104. The T-shaped slot 108 and the T-shaped block 501 slide together to slide the collection box 5 behind the extractor 1. The slag discharge conveyor belt 2 and the conveyor belt scraper 201 cooperate with each other. The conveyor belt scraper 201 can scrape off the residue adhering to the surface of the slag discharge conveyor belt 2 to prevent the residue from entering the gaps inside the slag discharge conveyor belt 2.

[0026] Example 3 Several arc-shaped scrapers 303 are fixedly attached to the outer wall of the drive shaft 301 near the lower edge. The lower part of the arc-shaped scrapers 303 is attached to the bottom of the extraction tank 101. A roller scraper 402 is fixedly attached to the bottom of the mounting frame 4. The lower end of the roller scraper 402 is attached to the outer wall of the slag pressure roller 401. A limit head 405 is fixedly attached to the upper end of the connecting slide rod 403. Several heaters 6 are fixedly attached to the inner wall of the extraction tank 101. The bottom of the extraction tank 101 is sloped. The slag discharge conveyor belt 2 rises slowly with the slope.

[0027] In this embodiment, the arc-shaped scraper 303 can scrape the raw material at the bottom of the extraction tank 101 onto the slag discharge conveyor belt 2. At the same time, the lower part of the arc-shaped scraper 303 is attached to the bottom of the extraction tank 101. When the arc-shaped scraper 303 rotates, it will scrape off the raw material residue that has accumulated and blocked the filter screen 103, thus preventing the filter screen 103 from being blocked by the accumulated raw material residue. The lower end of the roller scraper 402 is attached to the surface of the slag pressure roller 401. When the slag pressure roller 401 rotates, the roller scraper 402 can scrape off the adhered raw material residue. The heater 6 can be used to heat the medicine inside the extraction tank 101. The back of the extraction tank 101 is sloped, so that as the raw material is moved upward by the slag discharge conveyor belt 2, the leachate can flow naturally into the extraction tank 101 as the height increases.

[0028] The working principle and usage process of this invention are as follows: During use, the pre-treated raw materials and medicinal liquid are added into the extraction tank 101. The stirring mechanism is activated to thoroughly mix the raw materials and medicinal liquid. The heater 6 is activated to heat the medicinal liquid to 60-80°C, causing the polysaccharides inside the raw materials to fully precipitate into the medicinal liquid. After the raw materials have precipitated and soaked for a certain period, the slag discharge conveyor belt 2 is activated to carry the raw materials that have settled at the bottom. The precipitated raw materials are then transported to the collection box 5 using the slag discharge conveyor belt 2. During the transport process, a roller pressing mechanism is used to squeeze out the medicinal liquid from the transported raw materials. Then, the discharge connection pipe 104 is manually opened, allowing the leachate to be discharged through the valve 105, thus achieving effective extraction of plant polysaccharides.

[0029] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
