Description

Technical Field

[0001] This utility model belongs to the field of bio-extraction technology and relates to an apple stem cell raw material processing device, particularly an apple stem cell small molecule peptide purification raw material processing device. Background Technology

[0002] Apple stem cells, rich in bioactive small molecule peptides, show broad application prospects in the fields of cosmetics, pharmaceuticals, and health products. Small molecule peptides are easily absorbed and highly active, but their purification efficiency and quality are highly dependent on the pretreatment process of the raw materials.

[0003] Currently, the raw material processing of apple stem cells includes steps such as crushing, solvent extraction, and solid-liquid separation. However, there are problems such as incomplete cell crushing, insufficient release of small molecule peptides, low purification yield, easy clogging of traditional separation methods such as plate and frame filtration, and difficulty in removing filter cake. This makes continuous operation impossible, requires frequent shutdowns for cleaning, and results in a small processing capacity.

[0004] In addition, traditional high-temperature concentration or chemical treatment methods can easily lead to denaturation or degradation of small molecule peptides, affecting the purity and bioactivity of the final product.

[0005] Therefore, we propose a raw material processing device for the purification of small molecule peptides from apple stem cells. Through a wedge-shaped inclined plane design, the material is allowed to flow by gravity and the crushing path is extended, improving the efficiency of primary crushing. An integrated design of the primary crushing mechanism, plunger pump, and homogenizing valve forms a closed high-pressure homogenization process. The triple synergistic effect efficiently breaks down cell walls, significantly improving the extraction yield. With the automated coordination of the electric stirring tank and the liquid pump, as well as the self-cleaning system of the vibrating screen and the removable filter membrane, the entire process is automated and easy to maintain, ensuring continuous and stable production. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a raw material processing device for the purification of small molecule peptides from apple stem cells. The technical problem this invention aims to solve is: how to efficiently process apple stem cell raw materials through the processing device, so that apple stem cells can safely and fully release small molecule peptides and improve the extraction yield of small molecule peptides.

[0007] The objective of this utility model can be achieved through the following technical solutions: A raw material processing device for purifying small molecule peptides from apple stem cells includes an external water tank, a stirring and hydrolysis mechanism, and a primary crushing mechanism, a multi-stage filtration mechanism, and a waste bin arranged sequentially from front to back. The primary crushing mechanism includes a support frame and a crusher. The crusher is located on the upper end of the support frame. A plunger pump is located on the inner front part of the support frame. The inlet of the plunger pump is connected to the outlet of the crusher through a pipe. The outlet of the plunger pump is connected to a homogenizing valve located inside the support frame. The stirring and hydrolysis mechanism is located below the support frame. The stirring and hydrolysis mechanism is connected to the homogenizing valve through a pipe. The stirring and hydrolysis mechanism is connected to the multi-stage filtration mechanism through a pipe. The external water tank is connected to the multi-stage filtration mechanism through a pipe.

[0008] The working principle of this utility model is as follows: Apple raw materials first enter the primary crushing mechanism, where the crusher crushes the raw materials. The crushed material is then drawn by a plunger pump through a pipeline and pumped into a homogenizing valve for fine crushing. The finely crushed material enters the stirring and hydrolysis mechanism. After crushing, the operator adds a hydrolysis solvent into the stirring and hydrolysis mechanism, which then stirs and hydrolyzes the material. The hydrolyzed material is then transported through a pipeline to a multi-stage filtration mechanism for graded filtration, removing solid residue from the hydrolyzed liquid step by step. Finally, the filtered solid residue is collected in a waste bin. After filtration, an external water tank supplies water to clean the multi-stage filtration mechanism. The filtered liquid is collected and sent to the subsequent purification process.

[0009] The upper surface of the support frame is inclined, and a discharge clearance opening is provided on the front side of the upper surface of the support frame. The crusher is installed on the upper surface of the support frame, and a discharge pipe is fixed at the lower front side of the crusher. The discharge pipe is connected to the inside of the crusher, and a collection funnel is provided at the lower end of the discharge pipe.

[0010] With the above structure, the inclined surface at the upper end of the support frame supports the crusher. The workers put the apple raw materials into the crusher from the rear side. The crusher crushes the apple raw materials. The crushed apple pulp can flow naturally to the lower front end by gravity, prolonging the residence time of the material in the crusher. The apple pulp is discharged through the discharge pipe fixed on the crusher and is finally collected and guided by the collection funnel below.

[0011] The lower end of the collecting funnel is connected to the inlet of the plunger pump via a pipe passing through the discharge clearance port, and the outlet of the plunger pump is connected to the inlet of the homogenizing valve.

[0012] Using the above structure, the apple pulp collected by the collecting funnel is conveyed through the conveying pipe passing through the discharge clearance port at its lower end to the plunger pump inlet fixed inside the front of the support frame. The plunger pump then pressurizes the apple pulp to a preset pressure and conveys it to the inlet of the homogenizing valve. The high-pressure pulp is forced through the micron-level gaps of the homogenizing valve. At the moment of passing through the gaps, the pulp undergoes extremely high shear force, high-speed impact, and violent cavitation effect in sequence. The cell walls of the apple stem cells are completely destroyed, and small molecule peptides and other substances inside the cells are fully released into the pulp, which is then conveyed to the next process.

[0013] The stirring hydrolysis mechanism includes a fixed plate, with an electric stirring tank and a liquid pump at the upper end of the fixed plate. The electric stirring tank is located behind the liquid pump, and the upper end of the electric stirring tank is provided with an injection pipe and a feeding port. The liquid outlet of the electric stirring tank is connected to the liquid inlet of the liquid pump through a pipe. The liquid outlet of the homogenizing valve is connected to the feeding port through a pipe. The liquid outlet of the liquid pump is provided with a conveying pipe.

[0014] Using the above structure, the slurry treated by the homogenizing valve enters the electric mixing tank through the injection port via a pipeline. The operator adds the hydrolysis solvent into the tank through the injection pipe. The electric mixing tank stirs the mixture to allow it to undergo a full hydrolysis reaction. After the reaction is completed, the pump extracts the material through the outlet of the electric mixing tank and finally transports the hydrolyzed slurry to the next process through the conveying pipe.

[0015] The multi-stage filtration mechanism includes a liquid collection assembly, an inclined vibrating screen, and a liquid injection funnel arranged sequentially from bottom to top. The liquid collection assembly includes a liquid collection frame, a liquid collection hopper on the inner side of the liquid collection frame, and a filter membrane detachably mounted on the upper end of the liquid collection hopper. The vibrating screen is detachably mounted on the upper end of the liquid collection frame, and the position of the vibrating screen matches that of the liquid collection hopper. The liquid injection funnel is located on the upper rear side of the vibrating screen and is connected to a conveying pipe.

[0016] Using the above structure, the pump delivers the hydrolyzed slurry through the feed pipe to the injection funnel. The hydrolyzed slurry is then transported from the injection funnel to the vibrating screen, where it performs primary solids screening. During primary solids screening, the liquid processed by the vibrating screen continues to fall and undergoes fine filtration through a detachable filter membrane located at the top of the collection hopper. Finally, the liquid that has completed multi-stage filtration is collected through the collection hopper of the collection assembly, achieving solid-liquid separation and collection of the target product. The filter membrane is replaced periodically to maintain its filtration efficiency.

[0017] The front end of the vibrating screen is equipped with a slag guide plate, which is located above the garbage bin and extends into the garbage bin. The vibrating screen is equipped with a high-pressure micro pump, and several high-pressure nozzles are provided on both the left and right sides inside the vibrating screen. The high-pressure nozzles are all connected to the high-pressure micro pump through pipes.

[0018] With the above structure, after screening, the high-pressure micro pump draws water from the external water tank and delivers it to several high-pressure nozzles on both sides. The high-pressure nozzles spray high-pressure water to clean the screen. The waste residue produced by screening is pushed to the front guide plate under the action of vibration and slides into the garbage bin along the guide plate, completing the automatic slag discharge process.

[0019] Compared with existing technologies, this raw material processing device for the purification of small molecule peptides from apple stem cells has the following advantages: 1. The inclined surface design of the upper end of the support frame allows the apple pulp formed after crushing to flow out naturally by gravity, and increases the residence time of the material in the crusher, making the primary crushing more thorough.

[0020] 2. By closely connecting the primary crushing mechanism, the plunger pump, and the homogenizing valve, a continuous and closed-loop process is achieved from coarse crushing of raw materials to fine crushing at the cell level. The homogenizing valve utilizes the high pressure generated by the plunger pump to subject the apple pulp to a triple synergistic effect of shearing, impact, and cavitation, which can destroy the apple stem cell wall and improve the release efficiency and purification yield of small molecule peptides.

[0021] 3. The combination of electric mixing tank and liquid pump enables the automation of hydrolysis reaction and material conveying. The vibrating screen is equipped with high-pressure micro pump and nozzle for automatic cleaning. The filter membrane is detachable for easy regular replacement, cleaning and maintenance. At the same time, the combination of slag guide plate and waste bin realizes automatic collection and discharge of waste residue, reducing manual intervention and ensuring the continuity and stability of production.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1-6 As shown, the raw material processing device for purifying small molecule peptides from apple stem cells includes an external water tank, a stirring and hydrolysis mechanism 4, and a primary crushing mechanism, a multi-stage filtration mechanism, and a waste bin 1 arranged sequentially from front to back. The primary crushing mechanism includes a support frame 5 and a crusher 6. The crusher 6 is located on the upper end of the support frame 5. A plunger pump 7 is located on the inner front part of the support frame 5. The inlet of the plunger pump 7 is connected to the outlet of the crusher 6 through a pipe. The outlet of the plunger pump 7 is connected to a homogenizing valve 3, which is located inside the support frame 5. The stirring and hydrolysis mechanism 4 is located below the support frame 5. The stirring and hydrolysis mechanism 4 is connected to the homogenizing valve 3 through a pipe. The stirring and hydrolysis mechanism 4 is connected to the multi-stage filtration mechanism through a pipe. The external water tank is connected to the multi-stage filtration mechanism through a pipe.

[0031] In this embodiment, the apple raw material first enters the primary crushing mechanism, where the crusher 6 crushes the raw material. The crushed material is then drawn by the plunger pump 7 through a pipeline and pumped into the homogenizing valve 3 for fine crushing. The finely crushed material enters the stirring hydrolysis mechanism 4. After crushing, the operator adds a hydrolysis solvent into the stirring hydrolysis mechanism 4, which then stirs and hydrolyzes the material. The hydrolyzed material is then transported through a pipeline to a multi-stage filtration mechanism for graded filtration, removing solid residue from the hydrolyzed liquid step by step. Finally, the filtered solid residue is collected in the waste bin 1. After filtration, water is supplied from an external water tank to clean the multi-stage filtration mechanism. The filtered liquid is collected and sent to the subsequent purification process.

[0032] The upper surface of the support frame 5 is inclined, and a discharge clearance opening is provided on the front side of the upper surface of the support frame 5. The crusher 6 is installed on the upper surface of the support frame 5. A discharge pipe 10 is fixed at the lower front side of the crusher 6. The discharge pipe 10 is connected to the inside of the crusher 6. A collection funnel 11 is provided at the lower end of the discharge pipe 10.

[0033] In this embodiment, the inclined surface at the upper end of the support frame 5 supports the crusher 6. The worker puts the apple raw material into the crusher 6 from the rear side. The crusher 6 crushes the apple raw material. The crushed apple pulp can flow naturally to the lower front end by gravity, prolonging the residence time of the material in the crusher. The apple pulp is discharged through the discharge pipe 10 fixed on the crusher 6 and is finally collected and guided by the collection funnel 11 below.

[0034] The lower end of the collecting funnel 11 is connected to the inlet of the plunger pump 7 through a pipe passing through the discharge clearance port, and the outlet of the plunger pump 7 is connected to the inlet of the homogenizing valve 3.

[0035] In this embodiment, the apple pulp collected by the collecting funnel 11 is conveyed through the conveying pipe passing through the discharge clearance port at its lower end to the inlet of the plunger pump 7 fixed inside the support frame 5. The plunger pump 7 then pressurizes the apple pulp to a preset pressure and conveys it to the inlet of the homogenizing valve 3. The high-pressure pulp is forced through the micron-level gaps of the homogenizing valve. At the moment of passing through the gaps, the pulp undergoes extremely high shear force, high-speed impact and violent cavitation effect in sequence. The cell walls of the apple stem cells are completely destroyed, and small molecule peptides and other substances inside the cells are fully released into the pulp, which is then conveyed to the next process.

[0036] The stirring hydrolysis mechanism 4 includes a fixed plate 16. An electric stirring tank 12 and a liquid pump 13 are provided on the upper end of the fixed plate 16. The electric stirring tank 12 is located behind the liquid pump 13. The upper end of the electric stirring tank 12 is provided with an injection pipe 17 and a material inlet 15. The outlet of the electric stirring tank 12 is connected to the inlet of the liquid pump 13 through a pipe. The outlet of the homogenizing valve 3 is connected to the material inlet 15 through a pipe. A conveying pipe 14 is provided on the outlet of the liquid pump 13.

[0037] In this embodiment, the slurry treated by the homogenizing valve 3 enters the electric mixing tank 12 through the injection port 15 via a pipeline. The operator adds the hydrolysis solvent into the tank through the injection pipe 17. The electric mixing tank 12 stirs the mixture to allow it to undergo a full hydrolysis reaction. After the reaction is completed, the pump 13 extracts the material through the outlet of the electric mixing tank 12 and finally transports the hydrolyzed slurry to the next process through the conveying pipe 14.

[0038] The multi-stage filtration mechanism includes a liquid collection assembly 2, an inclined vibrating screen 8, and a liquid injection funnel 9 arranged sequentially from bottom to top. The liquid collection assembly 2 includes a liquid collection frame 19, a liquid collection hopper 20 is provided on the inner side of the liquid collection frame 19, and a filter membrane 21 is detachably provided on the upper end of the liquid collection hopper 20. The vibrating screen 8 is detachably arranged on the upper end of the liquid collection frame 19, and the position of the vibrating screen 8 matches that of the liquid collection hopper 20. The liquid injection funnel 9 is located on the rear side of the upper end of the vibrating screen 8 and is connected to the feed pipe 14.

[0039] In this embodiment, the pump 13 delivers the hydrolyzed slurry to the injection funnel 9 via the feed pipe 14. The hydrolyzed slurry is then delivered from the injection funnel 9 to the vibrating screen 8. The vibrating screen 8 performs primary solid sieving on the hydrolyzed slurry. During primary solid sieving, the liquid processed by the vibrating screen 8 continues to fall and undergoes fine filtration through the filter membrane 21, which is detachably installed at the top of the collection hopper 20. Finally, the liquid that has completed multi-stage filtration is collected through the collection hopper 20 of the collection assembly 2, realizing solid-liquid separation and collection of the target product. The filter membrane is replaced periodically to maintain its filtration effect.

[0040] The front end of the vibrating screen 8 is provided with a slag guide plate 18, which is located above the garbage bin 1 and extends into the garbage bin 1. The vibrating screen 8 is equipped with a high-pressure micro pump, and several high-pressure nozzles are provided on the left and right sides inside the vibrating screen 8. The high-pressure nozzles are all connected to the high-pressure micro pump through pipes.

[0041] In this embodiment, after the vibrating screen 8 performs screening, a high-pressure micro pump draws water from the external water tank and delivers it to several high-pressure nozzles on both sides. The high-pressure nozzles spray high-pressure water to clean the screen. The waste residue generated during screening is pushed to the front guide plate 18 under the action of vibration and slides into the garbage bin 1 along the guide plate 18, completing the automatic slag discharge process.

[0042] The working principle of this utility model is as follows: Apple stem cell raw materials first enter the primary crushing mechanism and are crushed by the crusher 6. The inclined surface at the upper end of the support frame 5 supports the crusher 6, so that the crushed apple pulp can be discharged through the discharge pipe 10 by gravity and collected by the collection funnel 11. The apple pulp collected by the collection funnel 11 is transported through the conveying pipe passing through the discharge clearance port to the plunger pump 7 fixed inside the front of the support frame 5. The plunger pump 7 pressurizes the pulp and pumps it into the homogenizing valve 3. The high-pressure pulp is forced through the micron-level gaps of the homogenizing valve 3. After experiencing extremely high shear force, high-speed impact and violent cavitation effect, the cell wall of the apple stem cells is completely destroyed, and small molecule peptides and other substances in the cells are fully released. After homogenization, the slurry enters the electric mixing tank 12 through the injection port 15 via a pipeline. After the operator adds the hydrolysis solvent through the liquid injection pipe 17, the electric mixing tank 12 stirs and hydrolyzes the mixture. After the reaction is completed, the liquid pump 13 extracts the hydrolyzed slurry and transports it to the multi-stage filtration mechanism through the conveying pipe 14. The hydrolyzed slurry enters the vibrating screen 8 through the injection funnel 9. The vibrating screen 8 performs primary solids screening on the hydrolyzed slurry. During screening, the liquid falls to the filter membrane 21 at the top of the collection hopper 20 for fine filtration. The liquid that has completed multi-stage filtration is collected by the collection hopper 20. At the same time, the vibrating screen 8 starts a high-pressure micro pump after screening, drawing water from the external water tank and cleaning the screen through high-pressure nozzles. The waste residue generated during screening is pushed to the front guide plate 18 under vibration and slides into the waste bin 1 along the guide plate 18, completing automatic slag discharge. The filtered liquid is collected and sent to the subsequent purification process to achieve solid-liquid separation and efficient extraction of the target product.

[0043] In summary, the inclined surface design of the upper end of the support frame 5 allows the apple pulp formed after crushing to flow out naturally by gravity, and prolongs the residence time of the material in the crusher, making the primary crushing more thorough. By closely connecting the primary crushing mechanism, the plunger pump 7 and the homogenizing valve 3, a continuous and closed-loop process from coarse crushing of raw materials to fine crushing at the cell level is achieved. The homogenizing valve 3 utilizes the high pressure generated by the plunger pump 7 to make the apple pulp undergo a triple synergistic effect of shearing, impact and cavitation, which can destroy the apple stem cell wall and improve the release efficiency and purification yield of small molecule peptides. The combination of electric mixing tank 12 and liquid pump 13 enables the automation of hydrolysis reaction and material conveying. Vibrating screen 8 is equipped with high-pressure micro pump and nozzle for automatic cleaning. Filter membrane 21 is detachable for easy replacement, cleaning and maintenance.
