Description

Technical Field

[0001] This utility model relates to the field of Dendrobium polysaccharide pulp preparation, specifically to a high-efficiency preparation system for Dendrobium polysaccharide pulp. Background Technology

[0002] Dendrobium polysaccharides are an important functional active substance extracted from Dendrobium, which has multiple functional activities such as anti-tumor, antioxidant, and immune enhancement.

[0003] Due to the colloidal properties of Dendrobium polysaccharides, dried Dendrobium strips are typically crushed before extraction. This process maximizes the preservation of the polysaccharides. The preparation of Dendrobium polysaccharide pulp requires Dendrobium particles of suitable size as raw materials. However, Dendrobium polysaccharides are sticky, and ordinary multi-stage screening devices may experience filter blockage by small Dendrobium particles, which can delay subsequent preparation processes and reduce production efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem of filter clogging caused by crushed Dendrobium officinale particles after screening, and to provide a high-efficiency preparation system for Dendrobium officinale polysaccharide pulp. This high-efficiency preparation system for Dendrobium officinale polysaccharide pulp can solve the problem of easy clogging when filtering Dendrobium officinale particles through a sieve.

[0005] To achieve the above objectives, this utility model provides a high-efficiency preparation system for Dendrobium polysaccharide pulp, including a multi-stage screening device. The multi-stage screening device includes a base, with several elastic connectors connected to the upper surface of the base. A shell is fixedly connected above the elastic connectors, and a vibration motor is fixedly connected to the outer surface of the shell. A first sieve plate is fixedly connected to the inner wall of the shell. A second sieve plate extends in the same direction below the first sieve plate and is fixedly connected to the inner wall of the shell. The second sieve plate has a hollow structure, with a sieve layer and a fixing layer respectively at its top and bottom. Several elastic balls are disposed between the sieve layer and the fixing layer. A first smooth plate is fixedly connected to the inner wall of the shell between the second sieve plate and the first sieve plate. A second smooth plate extends in the same direction below the second sieve plate and is fixedly connected to the inner wall of the shell.

[0006] Preferably, the base is further provided with a collection component, which includes a side plate and a guide plate. The side plate is slidably connected to the base along the length direction of the base, and the guide plate is disposed on the side plate for exporting the Dendrobium particles after grading and screening.

[0007] Preferably, the bottom end of the side plate is provided with a slider, and the base is provided with a slide rail.

[0008] Preferably, the outer casing has an opening on the side near the collecting assembly, and an inlet funnel is provided at the top of the end of the outer casing away from the side plate.

[0009] Preferably, the angle between the screen surface of the first screen plate and the horizontal plane is 5 to 15°.

[0010] Preferably, the angle between the surface of the first smooth plate and the horizontal plane is 165-175°.

[0011] Preferably, the hollow portion of the second sieve plate is provided with a partition plate to form a plurality of isolation spaces between it and the sieve layer and the fixed layer.

[0012] Preferably, the fixing layer is provided with a plurality of through holes, the diameter of which is set to allow the raw material to pass through while preventing the elastic ball from passing through.

[0013] Preferably, the mesh count of the first sieve plate is smaller than the mesh count of the sieve layer.

[0014] According to another aspect of the present invention, a Dendrobium polysaccharide pulp preparation system is provided, including a grading and screening device, wherein the grading and screening device is the grading and screening device described above.

[0015] The above technical solution cleans fine Dendrobium particles from the sieve layer by setting elastic balls between the sieve layer and the fixed layer of the second sieve plate. When the vibrating motor runs, it drives the outer shell and its internal components to move up and down on the base through elastic connectors. Dendrobium particles are poured into the outer shell and first pass through the first sieve plate. Dendrobium particles that do not pass the screening will flow out of the outer shell. Dendrobium particles that pass the screening will fall onto the first smooth plate and then fall down the first smooth plate into the second sieve plate for secondary screening. Dendrobium particles that do not pass the secondary screening will also flow out of the outer shell. Dendrobium particles that pass the secondary screening will fall onto the second smooth plate and then flow out of the outer shell. While screening is being performed on the sieve layer of the second sieve plate, the vibrating motor provides a vibration source, and the elastic balls also collide with the sieve layer, causing the sieve layer to vibrate, thereby removing the Dendrobium particles adhering to the sieve layer. This effectively solves the problem of reduced production efficiency caused by Dendrobium particles adhering to the sieve mesh. Attached Figure Description

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] Due to the properties of Dendrobium polysaccharides, the current method for preparing Dendrobium polysaccharide pulp typically involves crushing dried Dendrobium strips and then treating them with high-temperature water. Several factors influence the quality of the pulp during preparation, with the particle size of the crushed Dendrobium particles significantly affecting the viscosity. Experiments show that, under the same conditions, smaller particle sizes result in higher viscosity pulp. However, excessively small particle sizes make filtration of particulate matter in the final process extremely difficult. Therefore, selecting Dendrobium particles of suitable size is crucial. Industrially, grading and screening devices are commonly used to select particles of appropriate size. However, due to the viscosity of Dendrobium polysaccharides, existing grading and screening devices often cause small Dendrobium particles to stick to the filter inlets and clog the filter layer. Therefore, a grading and screening device that prevents particle clogging is needed.

[0023] like Figure 1-3As shown, this utility model provides a high-efficiency preparation system for Dendrobium polysaccharide pulp, including a multi-stage screening device. The screening device includes a base 1, with several elastic connectors 8 connected to the upper surface of the base 1. A shell 2 is fixedly connected above the elastic connectors 8, and a vibration motor 3 is fixedly connected to the outer surface of the shell 2. A first sieve plate 4 is fixedly connected to the inner wall of the shell 2. A second sieve plate 5 extends in the same direction below the first sieve plate 4 and is fixedly connected to the inner wall of the shell 2. The second sieve plate 5 is a hollow structure. A sieve layer 51 and a fixing layer 52 are respectively provided at the top and bottom of the second sieve plate 5. Several elastic balls 53 are provided between the sieve layer 51 and the fixing layer 52. A first smooth plate 6 is fixedly connected to the inner wall of the shell 2 between the second sieve plate 5 and the first sieve plate 4. A second smooth plate 7 extends in the same direction below the second sieve plate 5 and is fixedly connected to the inner wall of the shell 2.

[0024] Furthermore, a collection assembly is also provided on the base 1. The collection assembly includes a side plate 9 and a guide plate 91. The side plate 9 is slidably connected to the base 1 along its length, and the guide plate 91 is disposed on the side plate 9 for exporting the Dendrobium particles after grading and screening. A slider 92 is provided at the bottom end of the side plate 9, and a slide rail 93 is provided on the base 1. This design, by extending the guide plate 91 into the grading and screening device, allows the processed products to be accurately classified into different positions.

[0025] In some embodiments, an opening is provided on the side of the housing 2 near the collecting assembly, and a feeding funnel 21 is provided at the top of the end of the housing 2 away from the side plate 9.

[0026] According to the technical solution provided by this utility model, the screen surface of the first screen plate 4 forms an angle of 5-15° with the horizontal plane, and the plate surface of the first smooth plate 6 forms an angle of 165-175° with the horizontal plane. Since the second screen plate 5 and the second smooth plate 7 are parallel to the first screen plate 4, the second screen plate and the second smooth plate 7 form an angle with the horizontal plane, and the angle is the same as that of the first screen plate 4. The purpose of this design is to ensure that when the entire device vibrates, the raw material will gradually move from high to low along the inclined surface of this angle until it enters the guide plate 91 or the next layer. When the raw material passes through the first screen plate 4, the raw material with a particle size smaller than the screen holes of the first screen plate 4 will not fall directly onto the second screen plate 5, but will first fall onto the first smooth plate 6 and flow along the first smooth plate 6 to the upper part of the second screen plate 5. This setting is to allow the raw material to stay on the second screen plate 5 for a longer time for screening.

[0027] like Figure 3As shown, the hollow portion of the second sieve plate 5 is provided with an isolation plate 54 to form several isolation spaces between it and the sieve layer 51 and the fixed layer 52. The fixed layer has several through holes; the aperture of the through holes is set to allow raw materials to pass through while preventing the elastic balls from passing through. This design aims to make the elastic balls 53 more evenly distributed, preventing all the elastic balls 53 from being squeezed to the bottom, thus failing to perform their anti-clogging function, and ensuring that the elastic balls 53 can stably perform their anti-clogging function, avoiding the accumulation of elastic balls 53 at the bottom which would degrade the anti-clogging function.

[0028] According to the technical solution provided by this utility model, the mesh number of the first sieve plate 4 is less than the mesh number of the sieve layer 51.

[0029] In one embodiment provided by this utility model:

[0030] The first sieve plate 4 is set to a 10-mesh sieve, and the second sieve plate 5 is set to a 20-mesh sieve. Here, "mesh" refers to the number of sieve openings per inch. To avoid ambiguity, the mesh size is converted to a standard unit of length, meaning the sieve opening diameter of the first sieve plate 4 is set to 2 mm, and the sieve opening diameter of the second sieve plate 5 is set to 850 micrometers. Raw materials are poured into the feed funnel 21, initially at the top of the first sieve plate 4. As the vibrating motor 3 continues to vibrate, Dendrobium particles larger than 2 mm cannot pass through the sieve openings and gradually fall onto the top guide plate 91 and into the corresponding collection device. Particles smaller than 2 mm... The Dendrobium particles will fall onto the first smooth plate 6 at the bottom and slide into the second sieve plate 5. The particle size here is already small, and there is a risk of clogging the sieve layer 51. The elastic balls 53 in the second sieve plate 5 will collide with the sieve layer 51 due to vibration, thereby clearing the blockage. After the raw material is processed by vibration, the second sieve plate 5 will transport Dendrobium particles with a particle size greater than 850 micrometers to the middle guide plate 91. Dendrobium particles with a particle size less than 850 micrometers will fall onto the second smooth plate 7 and finally be output at the lowest guide plate 91, thereby realizing the function of graded screening, and keeping the sieve layer 51 with smaller sieve holes from being blocked in this process.

[0031] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
