[0018] The following is combined with Figure 1-7 This application is described in further detail.

[0019] The present application discloses a method for preparing an eggshell membrane extract containing cosmetic ingredients and a production device.

[0020] The method for preparing the eggshell membrane extract containing the beauty ingredient comprises the following steps: S1, washing and crushing the eggshells, and soaking them in an alkaline solution with a pH of 7.5-8.5, and collecting the eggshell membranes; S2, washing and drying the eggshell membranes, and then crushing the eggshell membranes and placing them in water; S3, heat water to 40-60°C, add dissolved keratinase solution, control pH in the range of 7-8.5 and stir for 3-5h; S4, heating the water to 65-70°C for 30-60 minutes to inactivate the enzyme, and filtering the solution; S5, further performing nanofiltration treatment on the filtered solution; S6. The nanofiltered solution is subjected to low-temperature drying treatment, and then ground into powder to obtain an eggshell membrane extract.

[0021] In this way, the eggshells are washed and crushed to improve the efficiency of the contact between the alkaline solution and the eggshell, thereby promoting the separation of the eggshell membrane and the eggshell. The eggshell membrane is then collected and crushed and dried to increase the contact area of ​​the eggshell membrane enzymatic hydrolysis, thereby improving the efficiency of the enzymatic hydrolysis. During the enzymatic hydrolysis process, keratinase is selected for enzymatic hydrolysis, and the controlled pH environment is similar to the environment in which the eggshell membrane is separated from the eggshell, thereby reducing the impact on the eggshell membrane during the separation of the eggshell membrane from the eggshell, thereby increasing the content of the beauty ingredients extracted by the enzymatic hydrolysis of the eggshell membrane, and finally the eggshell membrane extraction solution is dried and ground for standby use as a raw material to achieve efficient extraction of the beauty ingredients in the eggshell membrane.

[0022] The eggshell membrane extract production equipment containing beauty ingredients is used in the eggshell membrane separation process of the crushed eggshells in step S1.

[0023] refer to Figure 1 and Figure 2 The eggshell membrane extract production equipment containing beauty ingredients includes a barrel 1, a net barrel 3, a first telescopic cylinder 4, a piston barrel 2 and a motor 14.

The top of the extension tube 21 is connected with a plurality of nozzles 211, and the nozzle of the nozzle 211 is installed with a one-way membrane for only water to flow out. The inside of the barrel 1 is filled with a weak alkaline liquid, and the pH environment is 7.5-8.5.

[0024] Combination Figure 2 and Figure 3 The circumferential inner wall of the barrel 1 is provided with a plurality of water inlet holes 22, and the circumferential inner wall of the water inlet hole 22 near the inner side of the piston tube is provided with a closed annular groove 221, and the top of the closed annular groove 221 is rotatably connected with a closing plate 2211 capable of closing the water inlet hole 22. The first telescopic cylinder 4 is mounted on the top of the barrel 1, and the piston rod is downwardly arranged and fixed with a plug plate 41 that abuts and slides against the circumferential inner wall of the piston tube 2.

[0025] The net cylinder 3 is rotatably connected inside the barrel 1, and the inner ring of the net cylinder 3 abuts against the circumferential outer wall of the piston cylinder 2, and the outer ring of the net cylinder 3 abuts against the circumferential inner wall of the barrel 1. The inner ring of the net cylinder 3 is fixedly provided with a plurality of partitions 31 fixedly connected to the outer ring, and the partitions 31 are vertically arranged to divide the net cylinder 3 into a plurality of areas. The bottom of the partition 31 is located above the extension tube 21, and is fixedly provided with a partitioning mesh plate 32, through which the broken egg shells can pass. The bottom of the outer ring of the net cylinder 3 is fixedly provided with a plurality of collecting frames 33 below the extension tube 21, which are used to temporarily collect the fallen broken egg shells. The top of the outer ring of the net cylinder 3 is an outer gear ring 34, and a motor 14 is mounted on the top of the barrel 1. The rotating shaft of the click is fixedly provided with a driving gear 141 meshed with the outer gear ring 34, which is used to drive the net cylinder 3 to rotate at intervals, and each rotation will pass through an area separated by a partition 31. The inner ring, outer ring and partition 31 of the net cylinder 3 are all net plates, through which water can pass, and can intercept broken eggshells and eggshell membranes. A connecting groove is provided at the top of the partition 31 of the net cylinder 3, and the water level in the net cylinder 3 is higher than the bottom of the connecting groove. A plurality of circulating nozzles 23 are connected to the top of the piston cylinder 2, and the circulating nozzles 23 are all inclined along the same rotation direction, and in this embodiment, they are all facing the rotation direction of the net cylinder 3. The circulating nozzle 23 is located in the connecting groove area, and the inner ring of the net cylinder 3 is partially raised at the circulating nozzle 23 and partially opened to avoid it. A top plate 25 is fixed on the top of the circumferential inner wall of the piston cylinder 2, and the top plate 25 is located above the circulating nozzle 23. The circumferential inner wall of the top plate 25 is in contact with the piston rod of the first telescopic cylinder 4. The nozzle of the circulating nozzle 23 is also provided with a one-way membrane for only liquid spraying. The piston cylinder 2 is provided with a top cover 26 above the top plate 25, and a drainage hole 24 communicating with the barrel 1 is opened between the top cover 26 and the top plate 25. When the plug plate 41 moves to the lowest and highest positions, water inlet holes 22 are distributed above and below. A scooping assembly 5 for scooping out the eggshell membrane on the water surface is arranged on the top of the barrel 1. A collecting assembly 8 for collecting the broken eggshells in the collecting frame 33 is arranged at the bottom of the barrel 1. A feeding frame for feeding the crushed eggshells into the barrel 1 is arranged at the top of the barrel 1, directly above one of the areas of the net cylinder 3.

[0026] The washed and crushed eggshells are put into the barrel 1 and enter one of the areas of the net barrel 3. The eggshells sink to the bottom under gravity, and the separating mesh plate 32 intercepts the eggshells and separates them from the eggshell membranes under the immersion of the alkaline solution. The first telescopic cylinder 4 drives the plug plate 41 to move through the piston rod. During the downward movement of the plug plate 41, the plug plate 41 sprays the liquid below upward through the extension tube 21 and the nozzle 211, impacting the eggshells on the separating mesh plate 32, accelerating the efficiency of separating the eggshells and the eggshell membranes, wherein the broken eggshells that fall off will sink into the collecting frame 33 through the separating mesh plate 32, and then the broken eggshells and the eggshell membranes with the eggshells will be partitioned. The eggshell membrane will float up after the broken eggshells are continuously separated, and finally the eggshell membranes that can be felt will float on the water surface. The setting of the collecting tank 311 can connect the eggshell membranes floating on the water surface into an annular area. During the downward movement of the plug plate 41, under the action of water flow pressure, the closing plate 2211 will press against the closed ring groove 221, thereby reducing the flow of liquid from the water inlet hole 22. The water inlet hole 22 above the plug plate 41 will open the closing plate 2211 through the water flow under the action of pressure, so that the area above the plug plate 41 is filled with liquid.

[0027] During the upward movement of the plug plate 41, the plug plate 41 pressurizes the liquid above, and the liquid is sprayed out through the circulation nozzle 23, thereby causing the water on the surface of the barrel 1 to form a circulation, causing the eggshell membrane to flow in one direction, making it convenient to collect the eggshell membrane through the scooping component 5. The liquid in this part will flow out from the gap between the top plate 25 and the piston rod to the top of the top plate 25, and the top cover 26 is used to intercept the sprayed liquid, and allow the liquid between the top cover 26 and the top plate 25 to flow into the barrel 1 through the drainage hole 24.

[0028] The motor 14 can drive the net drum 3 to rotate intermittently by rotating, and then cooperate with the collecting component 8 for collecting the eggshells to realize the continuous work of separating and collecting the eggshells and eggshell membranes.

[0029] refer to Figure 4 and Figure 5, the scooping assembly 5 includes a rotating frame 51 and a scooping plate 52. The rotating frame 51 is arranged at the top of the barrel 1, and the rotating shaft is arranged horizontally. There are multiple scooping plates 52, which are fixed on the rotating frame 51 and can be inserted into the liquid in the barrel 1 as the rotating frame 51 rotates. The scooping plate 52 is provided with multiple holes for liquid to pass through. An outer ratchet 511 is fixed on the rotating shaft of the rotating frame 51, and a first pawl 512 is rotatably connected to the top of the barrel 1. The first pawl 512 is engaged with the outer ratchet 511 through a torsion spring, so that the rotating frame 51 can only drive the lowest scooping plate 52 to rotate upward against the water flow. The rotating frame 51 at the top of the barrel 1 is provided with a first bevel tooth 13 and a second bevel tooth 512 arranged vertically, the first bevel tooth 13 and the second bevel tooth 512 are engaged with each other, and the second bevel tooth 512 is rotatably sleeved on the rotating shaft of the rotating frame 51. An inner ratchet 5121 is fixedly provided on the circumferential inner wall of the second bevel gear 512, and a plurality of second pawls 513 meshing with the inner ratchet 5121 are rotatably connected to the rotating shaft of the rotating frame 51, and the second pawls 513 are pressed against the inner ratchet 5121 through a torsion spring. The tip of the inner ratchet 5121 faces in the opposite direction to the outer ratchet 511. A rack 83142 meshing with the first bevel gear 13 is fixedly provided on the side wall of the piston rod of the first telescopic cylinder 4. A second telescopic cylinder 6 is mounted on the top of the material frame, and a scraper 61 is fixedly provided on the piston rod of the second telescopic cylinder 6. A collecting material frame 7 is mounted on one side of the rotating frame 51 of the material frame, and the second telescopic cylinder 6 can drive the scraper 61 to hang the eggshell membrane on the scooping plate 52 into the collecting material frame 7.

[0030] The eggshell membrane floating on the water surface will flow to the scooping plate 52 and adhere to the scooping plate 52. During the movement of the piston rod of the first telescopic cylinder 4, the rack 83142 will mesh with the first bevel gear 13 and drive the second bevel gear 512 to rotate. Due to the arrangement of the first pawl 512 and the outer ratchet 511, the rotating frame 51 can only rotate in one direction. During the rotation of the second bevel gear 512, if the direction is the same as that in which the rotating frame 51 can rotate, the second pawl 513 will be clamped by the inner ratchet 5121 to drive the rotating frame 51 to rotate; if the rotation direction is opposite, the second pawl 513 will abut against the inner ratchet 5121 and rotate into the tooth groove of the next inner ratchet 5121, and the rotating frame 51 will remain stationary. Then, the automatic intermittent one-way rotation of the rotating frame 51 is realized by the movement of the piston rod of the first telescopic cylinder 4, so as to facilitate the upward rotation of the scooping plate 52. After the scooping plate 52 rotates to above the barrel 1 , the second telescopic cylinder 6 drives the scraper 61 to hang the eggshell membranes on the scooping plate 52 into the collecting frame 7 , thereby realizing automatic collection of the eggshell membranes.

[0031] refer to Figure 6 and Figure 7The collecting assembly 8 includes a collecting box 81, a net bag 82 and a closed door 83. The inner bottom wall of the barrel 1 is inclined downward at the end of the rotation direction of the net barrel 3 to open a feeding channel 11 connected to the outside. The collecting box 81 is fixed at the bottom of the circumferential outer wall of the barrel 1 and is connected to the feeding channel 11. A sealing cover is arranged on the top of the collecting box 81. The barrel 1 is provided with a closed groove 12 above the feeding channel 11, and the closed door 83 is vertically slidably connected in the closed groove 12 and can close the feeding channel 11. A tooth plate is fixed on the top of the closed door 83, and an adjusting rod 121 extending to the outside is rotatably connected in the closed groove 12. The adjusting rod 121 is fixed with an adjusting gear 1211 in the closed groove 12. The adjusting gear 1211 is meshed with the tooth plate, and the adjusting rod 121 is fixed with a hand wheel 1212 on the outside. A locking plate 1213 is slidably connected to the adjusting rod 121, and a locking groove 15 for inserting the locking plate 1213 is arranged on the outer wall of the barrel 1. The net bag 82 is arranged at the bottom of the collecting box 81 and can be taken out from the collecting box 81. A plurality of feeding nozzles 111 are installed at the bottom of the feeding channel 11. The feeding nozzles 111 are also installed with a one-way membrane for only spraying liquid. The feeding nozzles 111 are connected to the bottom of the piston cylinder 2.

[0032] The broken eggshells are located above the feeding channel 11 in the collection frame 33 as the net cylinder 3 rotates one circle, and the broken eggshells in the collection frame 33 enter the collection box 81 through the feeding channel 11. The provision of the feeding nozzle 111 can speed up the efficiency of the broken eggshells entering the collection box 81. When it is necessary to clean the broken eggshells in the collection box 81, the locking plate 1213 is pulled out from the locking groove 15, and the adjusting rod 121 is rotated so that the closed door 83 moves down and closes the feeding channel 11, and then the collection box 81 is opened, the net bag 82 is taken out, and the broken eggshells inside are recovered, and then the net bag 82 is reset and the collection box 81 is closed, and then the feeding channel 11 is opened to complete the collection of the broken eggshells, thereby improving the efficiency of the collection of the broken eggshells.

[0033] The one-way membrane mentioned is a rubber membrane structure commonly used in one-way valves or pipelines, which is a prior art and is not shown in detail in the drawings of this application.

[0034] The implementation principle of the eggshell membrane extract production equipment containing beauty ingredients is: the continuous collection of eggshells and eggshell membranes is realized by the rotation of the net tube 3. In the process of the plug plate 41 moving down, the liquid is sprayed from the nozzle 211 to impact the eggshell, and the efficiency of separating the eggshell and the eggshell membrane is accelerated by the alkaline liquid, and the broken eggshells that fall off pass through the separation net plate 32 and enter the collection frame 33. The fewer the broken eggshells on the eggshell membrane, the higher the position will be, and the eggshell membrane will directly float on the water surface, realizing three-dimensional partitioning. In the process of the plug plate 41 moving up, the water on the surface will also circulate through the circulation nozzle 23, and then drive the eggshell membrane to move to the scooping plate 52, which is convenient for the automatic scooping of the eggshell membrane. With the movement of the piston rod of the first telescopic rod, the rotating frame 51 will also be driven to rotate automatically in one direction, and the movement of the scraper 61 will realize the automatic scooping and collection of the eggshell membrane. The broken eggshells will enter the feeding channel 11 during the rotation of the net drum 3, and then enter the collection box 81, so that the broken eggshells can be automatically collected. This realizes the continuous process of automatic separation and classification recovery of eggshells and eggshell membranes, and improves the collection efficiency of eggshell membranes.

[0035] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
