Description

Technical Field

[0001] This invention relates to the field of fermented facial mask technology, specifically to a method for the aseptic separation and purification of fermented facial mask stock solution. Background Technology

[0002] Fermented masks are functional skincare products based on bio-fermentation technology. Their technology originates from traditional food fermentation processes and has been continuously optimized and upgraded in modern cosmetic processing. Fermented masks are functional masks prepared using microbial fermentation technology. The core of their processing lies in the precision separation technology of ceramic membrane filtration equipment. This technology uses inorganic materials such as alumina and zirconium oxide to sinter into ceramic membranes at high temperatures and adopts the cross-flow filtration principle: the fermentation liquid flows at high speed in the membrane tube, small molecule active ingredients pass through the membrane pores, while bacteria, large molecule impurities, etc. are intercepted. In existing technologies, when fermented facial mask stock solution is sterilely separated and purified using ceramic membrane filtration equipment, the clumps and ribbon-like foreign matter inherent in the fermented stock solution can easily enter and clog the interior of the ceramic membrane column. This clumps and ribbon-like foreign matter blockage of the membrane pores will significantly reduce the filtration flux, slow down the purification efficiency inside the ceramic membrane column, and delay the production schedule. Furthermore, the clumps and ribbon-like foreign matter blocking the interior of the ceramic membrane column will accumulate a large amount of ribbon-like foreign matter inside the ceramic membrane column over a long period of time, requiring repeated cleaning, which will wear down the membrane column and easily cause irreversible damage. Summary of the Invention

[0003] The purpose of this invention is to provide a sterile separation and purification method for fermented facial mask fermentation stock solution, so as to solve the problems mentioned in the background art.

[0004] The objective of this invention can be achieved through the following technical solutions: A method for aseptic separation and purification of fermented facial mask stock solution, comprising the following steps: S1. Pretreatment of fermented raw liquid: The fermented raw liquid of the mask is introduced into the pretreatment tank through the raw liquid inlet pipe of the ceramic membrane filter equipment, and the fermented raw liquid is refined through the various partition iron sheets to remove large particles of mycelium, residue and flocculents. S2. Clean the inside of the pretreatment tank: Use the backwash cleaning component to impact the spacer sheet in the reverse direction, and use the tapping component to clean the surface of the spacer sheet. S3. Pretreatment with ceramic membrane equipment: The fermentation broth from the pretreatment tank enters the ceramic membrane column, which is used to remove impurities and microorganisms from the fermentation broth, completing online sterilization and membrane activation. S4. Pressurized cross-flow filtration: The cross-flow filtration mode is adopted, and the raw liquid flows at high speed along the membrane surface. Small molecules pass through the ceramic membrane to become sterile filtrate, while large molecules are retained. S5. Pretreatment tank circulation concentration: The retentate is returned to the pretreatment tank for continuous circulation filtration. When the flux decreases, a small amount of sterile water is added in several batches for dialysis. S6. Aseptic Collection and Testing: The filtrate is connected to a clean collection tank through a sterile pipeline and is sealed throughout the process; samples are taken to test for microbial limits and clarity, and after passing the tests, it is transferred to the next process. S7. Membrane system cleaning and storage: After filtration, clean the membrane module and pipeline with alkaline solution and sterile water in sequence. Discharge the waste liquid from the waste liquid discharge pipe, rinse it clean, and then seal it for later use.

[0005] As a preferred technical solution of the present invention, the ceramic membrane column in S3 is made of 0.1-0.2μm sterile ceramic membrane components. The membrane channels are first rinsed with purified water, and then the interior of the ceramic membrane column is cleaned with 0.5% sodium hydroxide solution. The wastewater after cleaning is discharged from the waste liquid discharge pipe.

[0006] As a preferred technical solution of the present invention, the raw liquid inlet pipe and the waste liquid outlet pipe are respectively set at the bottom of both sides of the ceramic membrane filtration device. The pretreatment tank and the ceramic membrane column are arranged in sequence along the water flow direction of the ceramic membrane filtration device. The pretreatment tank is provided with a fixed column and several sets of backwash cleaning components inside, and the fixed column passes through the axial position of each backwash cleaning component.

[0007] As a preferred embodiment of the present invention, the backflushing cleaning assembly includes several spacer sheets, each spacer sheet being arranged at equal intervals inside the pretreatment tank. Each spacer sheet has several filter holes on its surface, which are used to filter ribbon-like foreign matter from the liquid inside the pretreatment tank. A fan blade and a backflushing ring are installed on the outside of the fixed column and above each spacer sheet. The fan blade is rotatably connected to the fixed column and rotates under the action of the liquid flow inside the pretreatment tank. The backflushing ring is fixed to the inner wall of the pretreatment tank and has a hollow center. A backflushing arc is formed on the lower surface of the backflushing ring, which performs reverse impact cleaning on the filter holes under the action of the flowing liquid.

[0008] As a preferred embodiment of the present invention, the backflush ring is welded to the inner wall of the pretreatment tank, and the plane of the spacer sheet is parallel to the plane of the backflush ring. The cross-section of the backflush ring is arc-shaped, and the edge thickness of the backflush ring is less than the middle thickness of the backflush ring. The backflush arc is used to reverse the flow of liquid in the pretreatment tank and impact the spacer sheet.

[0009] As a preferred technical solution of the present invention, a fixing ring is welded around the edge of the spacer sheet, and the fixing ring is welded to the inner wall of the pretreatment tank. The diameter of the filter holes of each spacer sheet increases from bottom to top, and the filter holes of different diameters are used to filter particles or ribbon-like foreign objects in the fermentation liquid of different particle sizes.

[0010] As a preferred embodiment of the present invention, a striking assembly is provided between the fan blade and the spacer sheet. The striking assembly includes two sets of threaded outer sleeves and threaded inner sleeves that are threaded together. A fixed frame and a rotating frame are respectively provided between the two sets of threaded outer sleeves and threaded inner sleeves that are screwed together. The two sets of threaded outer sleeves and threaded inner sleeves that are screwed together are used to define the positions of the fixed frame and the rotating frame. The lower threaded inner sleeve is fixed to the outer wall of the fixed column, and the upper threaded inner sleeve is slidably connected to the outer wall of the fixed column. Several connecting rods arranged in a circular array are provided between the rotating frame and the fan blade. Under the action of water flow inside the pretreatment tank, the rotating frame and the fan blade rotate synchronously, and the fixed frame and the rotating frame rotate relative to each other to strike the surface of the spacer sheet.

[0011] As a preferred technical solution of the present invention, a limiting sleeve is welded to the surface of the lower threaded inner sleeve. The limiting sleeve is located between the two threaded inner sleeves and is used to prevent the two threaded inner sleeves from sticking together. At least two telescopic springs are connected between the two threaded inner sleeves and are used to adjust the distance between the fixed frame and the rotating frame.

[0012] As a preferred technical solution of the present invention, the shape of the fixed frame and the shape of the rotating frame are both Y-shaped. The lower surface of the three supports of each rotating frame is provided with a reserved groove. A rotating cylinder and a cleaning brush are installed inside each reserved groove. The two ends of the rotating cylinder are rotatably connected to the two ends of the reserved groove. The cleaning brush is used to move the strip-shaped foreign objects at the filter hole or break the fermentation liquid clumps at the filter hole.

[0013] In a preferred embodiment of the present invention, when the three supports of the fixed frame and the three supports of the rotating frame overlap, the spacer sheet is located in the gap between the fixed frame and the rotating frame, and the strip-shaped foreign matter on the surface of the spacer sheet is moved by the rotating frame; or when the three supports of the fixed frame and the three supports of the rotating frame are staggered, the fermentation liquid clump at the filter hole of the spacer sheet is broken by the rotating frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Equipped with a backwash cleaning component, the fan blades rotate around the fixed column under the action of water flow. The strip-shaped foreign objects on the surface of the spacer sheet are rotated due to the influence of the fan blades. Smaller strip-shaped foreign objects are discharged from the filter holes of the spacer sheet, while larger strip-shaped foreign objects are retained on the surface of the spacer sheet, thus improving the purification efficiency. A backwash ring is provided, and the water flows along the backwash arc of the backwash ring. The backwash arc can flush the liquid back onto the surface of the spacer sheet, and the strip-shaped foreign objects on the spacer sheet are impacted by the water flow in the opposite direction, so as to prevent the strip-shaped foreign objects from clogging the filter holes of the spacer sheet. Equipped with a striking component, the fixed frame and rotating frame are used to process the strip-shaped foreign objects at the spacer sheet. When the fixed frame and rotating frame are close together, the rotating frame can move the strip-shaped foreign objects on the surface of the spacer sheet. When the fixed frame and rotating frame are staggered, the rotating frame can strike the strip-shaped foreign objects on the surface of the spacer sheet, thereby breaking up the fermentation liquid clump.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. Example

[0020] Please see Figure 1 As shown, a method for aseptic separation and purification of fermented facial mask stock solution includes the following steps: S1. Pretreatment of fermented stock solution: The fermented stock solution of the mask is fed into the pretreatment tank 4 through the stock solution inlet pipe 2 of the ceramic membrane filter equipment 1. The fermented stock solution is refined by the various spacer iron sheets 73 to remove large mycelial groups, residues and flocculants. The fermented stock solution of the mask is smoothly fed into the pretreatment tank 4 of the ceramic membrane filter equipment 1 by a sterile delivery pump. The pretreatment tank 4 is equipped with multiple layers of equidistant spacer iron sheets 73. During the flow of the stock solution, large mycelial groups, raw material residues, protein flocculants and colloidal aggregates are intercepted and removed. S2. Clean the inside of the pretreatment tank 4: Use the backwash cleaning component 7 to perform a reverse impact on the spacer sheet 73, and use the knocking component 8 to clean the surface of the spacer sheet 73. After the pretreatment is completed, use the liquid flow to drive the backwash cleaning component 7, and use sterile purified water to perform a reverse impact on the backwash ring 72 to wash away the residue and flocculent matter attached to the surface of the spacer sheet 73. S3. Pretreatment of Ceramic Membrane Equipment: The fermentation broth from pretreatment tank 4 enters ceramic membrane column 5. Ceramic membrane column 5 is used to remove impurities and microorganisms from the fermentation broth, completing online sterilization and membrane activation. The pretreated fermentation broth is then transported into the interior of ceramic membrane column 5, where it is steam-sterilized at 121℃ for 30 minutes. After cooling, it is rinsed with sterile water until neutral. Subsequently, membrane activation treatment is performed by circulating and cleaning with 0.1mol / L sodium hydroxide solution for 30 minutes. 0.1-0.2μm sterile ceramic membrane modules are selected for the interior of ceramic membrane column 5. The membrane channels are first flushed with purified water, and then the interior of ceramic membrane column 5 is cleaned with 0.5% sodium hydroxide solution. The wastewater after cleaning is discharged from waste liquid discharge pipe 3. S4. Pressurized cross-flow filtration: The cross-flow filtration mode is adopted, and the raw solution flows at high speed along the membrane surface. Small molecules pass through the ceramic membrane to become sterile filtrate, while large molecules are retained. The pressurized cross-flow filtration mode is adopted, and the operating pressure is controlled at 0.2-0.4MPa, the membrane surface flow velocity is 2-3m / s, and the raw solution flows at high speed parallel along the ceramic membrane surface. S5. Pretreatment Tank 4 Circulation Concentration: The retentate is returned to the pretreatment tank 4 for continuous circulation filtration. When the flux decreases, a small amount of sterile water is added in stages for dialysis. The retentate is located at the bottom of the pretreatment tank 4. Under the impact of sterile water at the bottom of the pretreatment tank 4, the retentate is diluted by the impact of sterile water on the retentate at the bottom of the pretreatment tank 4. Thus, the ceramic membrane retentate is kept in the pretreatment tank 4. The liquid entering the next tank is finer and more delicate. It is heated and concentrated in the next tank to increase the concentration of active ingredients. S6. Aseptic Collection and Testing: The filtrate is connected to a clean collection tank through a sterile pipeline and is sealed throughout the process. Samples are taken to test for microbial limits and clarity. If the test is qualified, the filtrate is transferred to the next process. The filtrate is directly connected to the sterile collection tank in the clean area through a fully sealed sterile pipeline. The collection process does not come into contact with the outside air to prevent secondary contamination. After collection, samples are taken and sent for testing under sterile conditions. If all indicators are qualified, the filtrate is transferred to the low-temperature sterile storage process to await the subsequent preparation of the face mask. S7. Membrane System Cleaning and Storage: After filtration, clean the membrane module and pipeline with alkaline solution and sterile water in sequence. Discharge the waste liquid from waste liquid discharge pipe 3. After rinsing, seal and store for later use. First, discharge the residual material. Then, use 1%-2% sodium hydroxide alkaline solution to circulate and clean the membrane module and pipeline for 40-60 minutes to remove organic pollutants such as proteins and polysaccharides. Next, circulate and rinse with sterile water until the discharged water has a neutral pH and no odor.

[0021] Please see Figure 2 - Figure 5 As shown, the raw liquid inlet pipe 2 and the waste liquid outlet pipe 3 are respectively set at the bottom of both sides of the ceramic membrane filter device 1. The pretreatment tank 4 and the ceramic membrane column 5 are arranged sequentially along the water flow direction of the ceramic membrane filter device 1. The pretreatment tank 4 is equipped with a fixed column 6 and several sets of backwash cleaning components 7. The fixed column 6 passes through the axis of each backwash cleaning component 7. The liquid enters from the raw liquid inlet pipe 2 of the ceramic membrane filter device 1 and enters the pretreatment tank 4. It is initially filtered by the pretreatment tank 4 to remove the ribbon-like foreign matter or fermentation liquid clumps in the fermentation raw liquid. The liquid is further processed by the ceramic membrane column 5, thereby purifying the fermentation raw liquid of the fermented face mask.

[0022] Please see Figure 4 and Figure 5As shown, the backflushing cleaning assembly 7 includes several spacer plates 73, which are evenly arranged inside the pretreatment tank 4. Each spacer plate 73 has several filter holes 75 on its surface. These filter holes 75 are used to filter ribbon-like foreign objects from the liquid inside the pretreatment tank 4. Because the filter holes 75 are arranged on the surface of the spacer plates 73, they can filter the ribbon-like foreign objects in the liquid, retaining larger objects on the lower surface of the spacer plates 73 and allowing smaller objects to pass through the filter holes 75. Furthermore, fan blades 71 and backflushing rings 72 are installed outside the fixed column 6 and above each spacer plate 73. The fan blades 71 are rotatably connected to the fixed column 6. The fan blades 71 are activated by the flow of liquid inside the pretreatment tank 4. As the liquid rotates, it flows from the lower end of the pretreatment tank 4 to the upper end. Under the action of the water flow, the fan blades 71 rotate. The fan blades 71 can carry the strip-shaped foreign objects on the surface of the spacer sheet 73, making the strip-shaped foreign objects on the surface of the spacer sheet 73 rotate. This is more conducive to carrying the strip-shaped foreign objects past the filter holes 75 of the spacer sheet 73. The backflushing ring 72 is fixed to the inner wall of the pretreatment tank 4. The backflushing ring 72 has a hollow center and a backflushing arc 76 is formed on the lower surface of the backflushing ring 72. Under the action of the flowing liquid, the backflushing arc 76 performs reverse impact cleaning on the filter holes 75. When the water flows through the backflushing arc 76 of the backflushing ring 72, some of the liquid is discharged along the tangent of the backflushing arc 76. Thus, the backflushing arc 76 reverses the impact of the strip-shaped foreign objects on the surface of the spacer sheet 73, reducing the long-term adhesion of the strip-shaped foreign objects to the spacer sheet 73 of the pretreatment tank 4.

[0023] Please see Figure 4 and Figure 5 As shown, the backflushing ring 72 is welded to the inner wall of the pretreatment tank 4. By welding the backflushing ring 72 to the inner wall of the pretreatment tank 4, the liquid flows through the middle of the backflushing ring 72. The plane of the spacer sheet 73 is parallel to the plane of the backflushing ring 72. The cross-section of the backflushing ring 72 is arc-shaped, and the edge thickness of the backflushing ring 72 is less than the middle thickness. The backflushing arc 76 is used to reverse the flow of liquid in the pretreatment tank 4 and impact the spacer sheet 73. Some liquid flows through the edge of the backflushing ring 72. Since the cross-section of the backflushing ring 72 is arc-shaped, the backflushing ring 72 is used to discharge the strip-shaped foreign matter at the filter hole 75 of the spacer sheet 73.

[0024] Please see Figure 4 and Figure 5As shown, a fixing ring 74 is welded around the edge of the spacer sheet 73. The fixing ring 74 is welded to the inner wall of the pretreatment tank 4. The diameter of the filter holes 75 of each spacer sheet 73 increases from bottom to top. The filter holes 75 of different diameters are used to filter particles or ribbon-like foreign objects in the fermentation liquid of different particle sizes. The spacer sheet 73 and the fixing ring 74 are fixed together. The fixing ring 74 is fixed to the inner wall of the pretreatment tank 4, so that the ribbon-like foreign objects can be cleaned by using the spacer sheet 73.

[0025] It should be noted that the liquid flows in from the raw liquid inlet pipe 2 of the ceramic membrane filtration device 1, and flows from the bottom to the top of the pretreatment tank 4. Under the action of the water flow, each fan blade 71 rotates. The rotation of the fan blade 71 drives the strip-shaped foreign objects on the surface of the spacer sheet 73 to rotate. After the strip-shaped foreign objects stuck on the surface of the spacer sheet 73 can rotate, smaller strip-shaped foreign objects can more easily pass through the filter holes 75 of the spacer sheet 73. At the same time, the water flows from the middle of the backwash ring 72. Due to the edge angle of the backwash ring 72, the liquid discharged from the backwash ring 72 can clean the spacer sheet 73. The strip-shaped foreign object is impacted, and some liquid flows along the backflow arc 76 of the backflow ring 72. The backflow arc 76 can reverse the liquid and impact the filter hole 75 of the spacer sheet 73. The strip-shaped foreign object at the filter hole 75 is detached from the filter hole 75. Due to the difference in flow velocity between the middle of the spacer sheet 73 and the edge of the spacer sheet 73, the strip-shaped foreign object on the lower surface of the spacer sheet 73 fluctuates, which helps to discharge the strip-shaped foreign object from the filter hole 75 of the spacer sheet 73. The fan blades 71 are rotated quickly to cut the strip-shaped foreign object. The strip-shaped foreign object can be cut finely enough by each fan blade 71.

[0026] Please see Figure 3 , Figure 6 - Figure 9As shown, a striking assembly 8 is provided between the fan blade 71 and the spacer sheet 73. The striking assembly 8 includes two sets of threaded outer sleeves 84 and threaded inner sleeves 85 that are threaded together. A fixing frame 81 and a rotating frame 82 are respectively provided between the two sets of threaded outer sleeves 84 and threaded inner sleeves 85. The two sets of threaded outer sleeves 84 and threaded inner sleeves 85 are used to define the positions of the fixing frame 81 and the rotating frame 82. The fixing frame 81 is placed between the lower threaded outer sleeve 84 and threaded inner sleeve 85, and the rotating frame 82 is placed between the threaded outer sleeve 84 and threaded inner sleeve 85, thereby defining the positions of the fixing frame 81 and the rotating frame 82. The lower threaded inner sleeve 85 is fixed to the outer wall of the fixing post 6, and the upper threaded inner sleeve 85 is slidably connected to the outer wall of the fixing post 6. The lower threaded inner sleeve 85 is welded to the fixing post 6, and the upper threaded inner sleeve 85 rotates with respect to the outside of the fixing post 6. The fan blade 71 causes the fixed frame 81 and the rotating frame 82 to rotate relative to each other. The fixed frame 81 is fixed, while the rotating frame 82 rotates relative to the fixed column 6. The upper surface of the fixed frame 81 and the lower surface of the rotating frame 82 will intermittently contact each other. Several connecting rods 83 arranged in a ring array are provided between the rotating frame 82 and the fan blade 71. Under the action of water flow inside the pretreatment tank 4, the rotating frame 82 and the fan blade 71 rotate synchronously. The relative rotation of the fixed frame 81 and the rotating frame 82 is used to strike the surface of the spacer sheet 73. The fan blade 71 rotates under the action of water flow. The fan blade 71 drives the rotating frame 82 to rotate around the fixed column 6 through the connecting rods 83. The rotating frame 82 can rotate relative to the fixed frame 81. At this time, the relative rotation of the fixed frame 81 and the rotating frame 82 can contact and strike the spacer sheet 73, thereby removing the strip-shaped foreign matter on the surface of the spacer sheet 73.

[0027] Please see Figure 6 - Figure 8 As shown, a limiting sleeve 86 is welded to the surface of the lower threaded inner sleeve 85. The limiting sleeve 86 is located between the two threaded inner sleeves 85. The limiting sleeve 86 is used to prevent the two threaded inner sleeves 85 from touching each other. The two threaded inner sleeves 85 in the same group can move closer or further away from each other. The upper rotating frame 82 and the fixed frame 81 can be moved closer or further away by using the limiting sleeve 86 between the two threaded inner sleeves 85. The limiting sleeve 86 can prevent the fixed frame 81 and the rotating frame 82 from getting too far apart. At least two telescopic springs 810 are connected between the two threaded inner sleeves 85. The telescopic springs 810 are used to adjust the distance between the fixed frame 81 and the rotating frame 82. The telescopic springs 810 are used to connect and limit the two threaded inner sleeves 85, which can prevent the two threaded inner sleeves 85 from moving too far apart.

[0028] Please see Figure 6 - Figure 9As shown, both the fixed frame 81 and the rotating frame 82 are Y-shaped. The Y-shaped fixed frame 81 and rotating frame 82 rotate relative to each other, so that the upper surface of the support of the fixed frame 81 and the lower surface of the support of the rotating frame 82 will intermittently contact each other. Each rotating frame 82 has a reserved groove 87 on the lower surface of its three supports. Each reserved groove 87 is equipped with a rotating cylinder 88 and a cleaning brush 89. The two ends of the rotating cylinder 88 are rotatably connected to the two ends of the reserved groove 87. The cleaning brush 89 is used to move the strip-shaped foreign objects at the filter hole 75 or break the fermentation liquid clumps at the filter hole 75. The cleaning brush 89 rotates around the inside of the rotating cylinder 88 of the reserved groove 87, so that the cleaning brush 89 can contact and tap the surface of the spacer sheet 73 to ensure that the strip-shaped foreign objects on the surface of the spacer sheet 73 are cleaned.

[0029] Please see Figure 8 and Figure 9 As shown, when the three supports of the fixed frame 81 and the three supports of the rotating frame 82 overlap, the spacer sheet 73 is located in the gap between the fixed frame 81 and the rotating frame 82. The strip-shaped foreign matter on the surface of the spacer sheet 73 is moved by the rotating frame 82, which can move and clean the strip-shaped foreign matter on the surface of the spacer sheet 73. Alternatively, when the three supports of the fixed frame 81 and the three supports of the rotating frame 82 are staggered, the fermentation liquid clump at the filter hole 75 of the spacer sheet 73 is broken by the rotating frame 82. When the three supports of the fixed frame 81 and the three supports of the rotating frame 82 are staggered, the rotating frame 82 is brought closer to the fixed frame 81 under the action of the extension spring 810, so that the cleaning brush 89 can tap the surface of the spacer sheet 73, causing the fermentation liquid clump on the surface of the spacer sheet 73 to be broken by the rotating frame 82.

[0030] It should be noted that the fan blade 71 rotates under the action of water flow, causing the fixed frame 81 and the rotating frame 82 to rotate relative to each other. Under the action of the telescopic spring 810, the rotating frame 82 and the fixed frame 81 move closer to each other. When the rotating frame 82 and the fixed frame 81 overlap, the strip-shaped foreign matter on the surface of the spacer sheet 73 is moved by the rotating frame 82, which can move and clean the strip-shaped foreign matter on the surface of the spacer sheet 73. When the rotating frame 82 and the fixed frame 81 are misaligned, the rotating frame 82 continues to move closer to the fixed frame 81 under the action of the telescopic spring 810, so that the cleaning brush 89 can tap the surface of the spacer sheet 73, causing the fermentation liquid clumps on the surface of the spacer sheet 73 to be broken by the rotating frame 82.
