Description

Technical Field

[0001] The utility model relates to the technical field of refiners, in particular to a multi-stage refiner and a cleaning device thereof. Background Art

[0002] Soy products are high in protein and low in fat, and have the effects of lowering blood pressure, blood lipids and cholesterol. They are complete in variety, with a variety of styles, unique flavor, simple production process and convenient consumption. They can be eaten raw or cooked, suitable for all ages, and are a good delicacy for health preservation and longevity. In the production process of soy products such as soy milk, grinding equipment is needed. The existing grinding equipment mainly includes knife grinding and grinding. Knife grinding uses a blade to rotate at high speed to cut the beans; while grinding is similar to traditional stone mills, and the beans are ground by the mutual movement of the upper and lower grinding discs. At present, for large-scale industrial production, most of its grinding equipment adopts grinding, that is, when the material that has been pre-treated by cleaning, soaking, etc. enters the hopper and enters the mill, it enters between the upper and lower grinding discs that move relatively under the action of centrifugal force. Due to the mutual impact and extrusion of the material and the shearing and tearing of the grinding disc, the material is ground from inside to outside and from coarse to fine along the plane of the grinding disc to achieve the purpose of grinding. Generally, there are two types: slag separation and non-separation.

[0003] Reference 1:

[0004] The utility model patent with the authorization announcement number CN206746684U and the invention name of an easy-to-clean slag slurry separation refiner discloses a refiner, which includes a support base, a refiner barrel and a refiner upper cover, wherein the refiner barrel is fixed at the top of the support base, the refiner upper cover is arranged on the refiner barrel, the refiner barrel includes a grinding liquid part and a liquid collecting part, a refiner motor is arranged inside the support base, a lower grinding plate is arranged at the top of the motor shaft, a stirring rod is connected to the top center of the lower grinding plate through a thread, the refiner upper cover includes an upper cover body, a feed funnel arranged at the top of the upper cover body, and a feed pipe arranged at the bottom of the upper cover body, and a slurry outlet and a cleaning water pipe are arranged on the side wall of the liquid collecting part of the refiner barrel. The slag slurry separation can be achieved through the ingeniously structured inclined filter screen and the slag outlet, and the upper grinding plate and the lower grinding plate are convenient for grinding high-purity and high-quality slurry through the stirring rod with a rotating thread and a crushing blade and the elastic design of the upper grinding plate.

[0005] As described in Document 1, most existing slag-slurry separation refiners adopt one-time refining, and the material is not effectively ground. There are still many nutrients in the slag after one-time refining and filtration, resulting in the discarding of slag with high nutrient content, low material grinding efficiency, and also reducing the grinding efficiency of the refiner.

[0006] In order to facilitate cleaning, a cleaning water pipe is provided in the liquid collecting part of the grinding barrel. The end of the cleaning water pipe is provided below the bottom of the lower grinding plate. The lower grinding plate is driven to rotate by the grinding motor to facilitate the cleaning of the grinding machine. Since the grinding motor is in working state during cleaning, there are many problems, such as the first one is that it is unsafe at a high speed of the motor (about 3000 revolutions per minute); the second one is that it is easy to cause water to enter the bearing, damage the bearing, and even the motor; the third one is that the cleaning is not thorough. Since the residual bean dregs are distributed on the inner wall of the conical filter screen with a certain thickness, the bottom of the conical filter screen cannot be completely cleaned during cleaning. The uncleaned bean dregs are prone to deterioration and mildew. When the machine is used next time, the harmful and toxic substances produced by the deterioration and mildew of the residual bean dregs will directly enter the soy milk and reduce the pulping rate.

[0007] In order to achieve effective grinding, Document 2: The invention patent application with publication number CN103533847A and the invention name of New Soymilk Production Method discloses a soymilk production method, wherein the soaked soybeans are ground in multiple stages and the ground liquid is filtered in multiple stages to recover the low-concentration soymilk for recycling, thereby improving the soymilk yield. This method reduces the amount of dregs produced after grinding and can improve the extraction rate of nutrients in the dregs.

[0008] To this end, Document 3: The utility model patent with authorization announcement number CN206304815U and invention name of a multi-stage soybean refiner discloses a multi-stage refiner, which includes a feed barrel, a shell and a base, a feed barrel is arranged at the upper end of the shell, the top end of the shell and the tail end of the feed barrel are connected by a feed pipe, a feeding auger is arranged horizontally inside the feed barrel, a material leveling plate is fixedly connected to the inside of the shell near the top end, a screen is fixedly connected to the lower end of the material leveling plate on the inner side wall of the shell, a cutting blade is arranged at the upper end of the screen, an upper grinding disc is arranged on the lower side of the screen, a fixed grinding disc is arranged at the lower end of the upper grinding disc, a lower grinding disc is arranged at the lower end of the fixed grinding disc, the cutting blade, the upper grinding disc and the lower grinding disc are all fixed on the rotating shaft, and the rotating shaft is connected to a second driving motor through a reducer. The utility model has a simple structure and a reasonable design, and can greatly improve the grinding quality of soybeans and the production quality of soy milk through multiple grindings, and can reduce power consumption through the reducer to further improve the grinding quality of soybeans.

[0009] Document 4: The invention patent application with publication number CN107597398A and invention name "A soybean multi-stage refining device for tofu production and processing" discloses a multi-stage refiner, which includes a bottom plate; after the soybeans enter the hopper, the rotation of the rotating plate causes the soybeans to be discharged, and then the soybeans are crushed by three crushing wheels to form smaller particles, which is convenient for improving the subsequent refining efficiency. The soybeans enter the gap between the first rotating stone mill and the first fixed stone mill through the first drop hole, and the soybeans are subjected to primary refining. Then the soybeans pass through the second drop hole and enter the gap between the second rotating stone mill and the second fixed stone mill, thereby undergoing secondary stone grinding. After two refining actions, the refining quality is obvious, and the ground soybean milk enters the inclined screen. Due to the incomplete gear, the frame moves back and forth left and right, thereby causing the inclined screen to move back and forth left and right, so that the soybean milk falls easily and the fluff residue enters the drop box.

[0010] Document 5: The utility model patent with the authorization announcement number CN210357488U and the invention name of a soybean refining device discloses a soybean refining device, which includes a first refiner and a second refiner arranged in sequence, the first refiner is a knife-grinding refiner, and its discharge end is sequentially connected to a coarse filter screen and a fine filter screen, the filter residue of the coarse filter screen is connected to the feed port of the second refiner through a return pipe, and the filter residue of the fine filter screen is connected to a filter press device, and is respectively connected to a slurry collection container and a slag collection container at the rear of the filter press device; and the second refiner is a disc refiner, and the disc refiner has a built-in solid-liquid separation device or an external solid-liquid separation device, the solid-slag discharge end of the solid-liquid separator is connected to the filter press device, and the slurry discharge end is connected to the slurry collection container. The utility model can realize continuous graded refining of soybeans, improve the utilization rate during wet grinding, and perform multi-stage slurry-slag separation, thereby ensuring the quality and fineness of the refined slurry.

[0011] The multi-stage pulping machines in Documents 3, 4, and 5 all perform slag-slurry separation after multi-stage grinding. Since the soy milk is not separated after each grinding, and the soy milk contains oil, the oily soy milk will increase the lubrication of the surface of the soybean dregs particles that have been ground once, resulting in the subsequent multiple grindings. The work efficiency and grinding effect are affected, and there are low grinding efficiency, low soybean milk efficiency, and low nutrient extraction rate in soybean dregs. At the same time, when cleaning the equipment, there are also many problems such as those described in Document 1, especially in Documents 3 and 4, due to the high height of the equipment, it is difficult to disassemble some structures for cleaning, and it is even more difficult to operate when the moving parts (such as bearings) are damaged and replaced.

[0012] In this regard, the most commonly used refining method in the industry is to use a combination of multiple slurry separation refiners for refining. This method achieves the purpose of sufficient refining through multiple grindings.

[0013] Document 6: The utility model patent with authorization announcement number CN207507616U and invention name "Triple Type Soybean Refiner" discloses a multi-stage refiner, which is provided with a hopper, a slag outlet and a liquid outlet on each cylinder body, and a bracket is provided under the three cylinder bodies.

[0015] However, Documents 6 and 7 have the problems of occupying large space, high energy consumption, high equipment cost, etc., and there are also many problems in cleaning as described in Document 1. At the same time, the operation process is relatively cumbersome, requires high proficiency of the operator, and has high labor intensity. Utility Model Content

[0062] In summary, the material and liquid conveying method in this application is carried out according to the following connection method:

[0063] The first slag outlet 209 of the first grinding device 2 is connected to the second feed port 306 of the second grinding device 3, and the second slag outlet 309 of the second grinding device 3 is connected to the third feed port 406 of the third grinding device 4;

[0064] The first liquid inlet 207 of the first grinding device 2 and the third liquid inlet 407 of the third grinding device 4 are connected to the refiner liquid supply device.

[0065] The second liquid inlet 307 of the second grinding device 3 is connected to the third liquid outlet 408 of the third grinding device 4;

[0066] The first liquid outlet 208 of the first grinding device 2 and the second liquid outlet 308 of the second grinding device 3 are respectively connected to the liquid collecting devices.

[0067] When this embodiment works:

[0068] The raw material (soaked soybeans in this embodiment) is poured into the first grinding device 2 through the feed hopper 101, and the second liquid pump 504 supplies liquid from the pulper liquid supply device (pure water in this embodiment) to the first grinding device 2 through the first liquid inlet 207. Under the action of centrifugal force, the soy milk and bean dregs ground by the first grinding device 2 are sent to the liquid collecting device through the filter on the first filter frame and the first liquid outlet 208; the bean dregs are thrown out from the first dregs outlet 209 and sent to the second grinding device 3 through the second dregs-liquid mixing chamber 312 and the second feed port 306 for further grinding.

[0069] The first liquid pump 503 supplies liquid to the second grinding device 3 from the third liquid outlet 408 through the second liquid inlet 307 and the second residue-liquid mixing chamber 312 with the soybean milk ground by the third grinding device 4. Under the action of centrifugal force, the soybean milk and soybean dregs ground by the second grinding device 3 are sent to the liquid collecting device through the filter on the second filter frame and the second liquid outlet 308; the soybean dregs are thrown out from the second residue outlet 309, and sent to the third grinding device 4 through the third residue-liquid mixing chamber 412 and the third feed inlet 406 for further grinding. The second liquid pump 504 supplies liquid to the third grinding device 4 from the pulper liquid supply device (pure water in this embodiment) through the third liquid inlet 407 and the third residue-liquid mixing chamber 412.

[0070] The soybean milk and bean dregs ground by the third grinding device 4 are sent to the second dregs-liquid mixing chamber 312 through the filter screen on the third filter screen frame and the third liquid outlet 408 by the first liquid pump 503 through the second liquid inlet 307 to supply liquid to the second grinding device 3; the bean dregs are thrown out from the third dregs outlet 409. The soybean milk sent to the liquid collecting device by the first liquid outlet 208 and the second liquid outlet 308 is a high-concentration, high-quality raw soybean milk product.

[0071] Since the dregs ground by the first grinding device 2 and the second grinding device 3 contain a certain amount of soy milk, after being thrown upward obliquely by the centrifugal force, it is difficult for the liquid supplied through the second liquid inlet 307 and the third liquid inlet 407 to be quickly and evenly mixed with the dregs and smoothly enter the grinding assembly through the second feed inlet 306 and the third feed inlet 406 to be ground.

[0072] The cleaning method of the multi-stage refiner of this embodiment is as follows:

[0073] Step a, separating the grinding devices: comprising step a1 and step a2, specifically as follows:

[0074] Step a1, from top to bottom, the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 are lifted upward one by one or simultaneously by a lifting force;

[0075] Step a2: From bottom to top, lower the third grinding barrel 410 by lifting power or using its own weight until the third grinding barrel 410 can rotate horizontally without obstruction, and rotate it horizontally away from the center of the grinder. In the same way as above, lower and horizontally rotate the second grinding barrel 310, the first grinding barrel 210 and the upper cover 1 one by one.

[0076] Step b, cleaning the grinding device;

[0077] Step c, resetting the grinding device: including step c1, step c2, and step c3, which are specifically as follows:

[0078] Step c1, from bottom to top, first rotate the third grinding barrel 410 to the center position of the grinder, and lower the third grinding barrel 410 to the working position by lifting power or using its own weight;

[0079] Step c2: In the same operation as step c1, lower the second grinding barrel 310, the first grinding barrel 210, and the upper cover 1 to the working position one by one;

[0080] Step c3: the first coupling 205, the second coupling 305, and the third coupling 405 are automatically locked, and the adjacent grinding barrel spindles and the third spindle 404 and the motor shaft 502 are quickly connected.

[0081] In this embodiment, the soybeans are ground in the first grinding device 2 at the first stage, ground in the second grinding device 3 at the second stage, and ground in the third grinding device 4 at the third stage.

[0082] During the first-stage grinding, soybeans are ground together with purified water. The soy milk after the first-stage grinding has a higher concentration and is directly transported to the liquid collecting device.

[0083] During the secondary grinding, the bean dregs after the primary grinding are mixed with the soy milk after the tertiary grinding and then subjected to the secondary grinding. Since the raw material liquid during the tertiary grinding is pure water and the dregs are the bean dregs after two grindings, the concentration of the soy milk after the tertiary grinding is relatively low. Using the soy milk with lower concentration as the raw material liquid for the secondary grinding can, on the one hand, reduce the oil content on the bean dregs after the primary grinding and improve the secondary grinding effect, and on the other hand, can also increase the original tertiary ground soy milk, thereby increasing the concentration of the soy milk after the secondary grinding.

[0084] The cleaning device is safe and efficient. Since the upper cover 1 and the grinding barrels can be separated, rotated and turned over, the bean dregs remaining in the inner walls of the conical filters in the pulping machine can be thoroughly cleaned with less water consumption, effectively preventing the deterioration and mildew caused by incomplete cleaning of the bean dregs.

[0085] Embodiment 2

[0086] Please see attached Figure 1 As shown, in order to prevent the slag and liquid from blocking the feed port due to the inability to mix quickly and evenly, the second slag and liquid mixing chamber 312 of the utility model is provided with a second auxiliary horizontal feeding auger 313, and the third slag and liquid mixing chamber 412 is provided with a third auxiliary horizontal feeding auger 413. In order to prevent the dregs from blocking the feed port, the second auxiliary horizontal feeding auger 313 of this embodiment is driven by the second auxiliary feeding motor 314, and the third auxiliary horizontal feeding auger 413 is driven by the third auxiliary feeding motor 414. For simplicity, the second auxiliary horizontal feeding auger 313 can also be driven by the first main shaft 204 after gear speed change, and the third auxiliary horizontal feeding auger 413 can also be driven by the second main shaft 304 after gear speed change.

[0087] In order to prevent the dregs from contacting the first main shaft 204 and the second main shaft 304 rotating at high speed and thus being difficult to enter the grinding assembly, the present embodiment provides a separation cylinder on the bearing seats where the first main shaft 204 and the second main shaft 304 are installed; in order to make the feeding of the dregs smoother, stirring blades are installed on each separation cylinder to make them become the second auxiliary vertical feeding augers 217 and the third auxiliary vertical feeding augers 315. At the same time, the second auxiliary vertical feeding augers 217 are driven by the first main shaft 204 after gear speed change, and the third auxiliary vertical feeding augers 315 are driven by the second main shaft 304 after gear speed change. In this way, the second auxiliary vertical feeding augers 217 and the third auxiliary vertical feeding augers 315 can smoothly feed the dregs coming from the second feeding port 306 and the third feeding port 406 into the grinding assembly for grinding, and at the same time, it also prevents the dregs from contacting the first main shaft 204 and the second main shaft 304 rotating at high speed and thus being difficult to enter the grinding assembly.

[0088] The multi-stage refiner cleaning method of this embodiment is the same as that of the first embodiment.

The upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 are respectively provided with a sleeve arm 603, each sleeve arm 603 is connected to a corresponding rotating sleeve 602 through a corresponding needle bearing 604, and each rotating sleeve 602 is correspondingly connected to a sliding sleeve 601 on the column 6 through a corresponding thrust bearing 605; a lifting rack 606 is provided on the column 6, and each sliding sleeve 601 is respectively provided with a lifting motor 607 and a lifting gear 608 meshing with the lifting rack 606, and each lifting gear 608 is respectively connected to the driving shaft of the corresponding lifting motor 607.

[0091] When in use, the lifting motor 607 drives the lifting gear 608 to rotate. Since the lifting gear 608 is meshed with the lifting rack 606, the sliding sleeve 601 connected to the lifting motor 607 is driven to move up and down along the column 6, thereby driving the corresponding upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 to move up and down along the column 6; the rotating sleeve 602 can rotate around the sliding sleeve 601 through the connection of the thrust bearing 605, thereby driving the corresponding upper cover 1 and each grinding barrel to rotate circumferentially along the column 6; the sleeve arm 603 can rotate around the rotating sleeve 602 through the connection of the needle bearing 604, thereby driving the corresponding upper cover 1 and each grinding barrel to flip upward. In summary, the auxiliary cleaning components are helpful to adjust the position and opening direction of the upper cover 1 and each grinding barrel, thereby facilitating cleaning and improving the degree of cleaning.

[0092] The cleaning method after the structure of this embodiment is integrated with that of the first embodiment and the second embodiment is as follows:

[0098] Step c, resetting the grinding device: including step c1, step c2, and step c3, which are specifically as follows:

[0099] Step c1, from bottom to top, first rotate the third grinding barrel 410 to the center position of the grinder, and then the lifting motor 607 on the third grinding barrel 410 rotates in the opposite direction to drive the corresponding lifting gear 608 to descend along the column 6 until the third grinding barrel 410 descends to the working position;

[0100] Step c2: In the same operation as step c1, the lifting motors 607 corresponding to the second grinding barrel 310, the first grinding barrel 210 and the upper cover 1 are driven to reverse one by one, and the lifting gear 608 is driven to descend along the column 6 until the second grinding barrel 310, the first grinding barrel 210 and the upper cover 1 descend to the working position;

[0101] Step c3: The first coupling 205, the second coupling 305 and the third coupling 405 are automatically locked, and the adjacent grinding barrel main shafts and the third main shaft 404 and the motor shaft 502 are quickly connected, so as to prevent the separation and damage between the transmission shafts of the grinding device.

[0102] Embodiment 4

[0103] Please refer to Appendix 1 and Appendix Figure 3 As shown, in order to improve the stability between the upper cover 1 and each grinding device and the frame 5 during grinding, this embodiment is provided with a locking device compared with the first, second and third embodiments, and the locking device is used to lock the upper cover 1, the first grinding barrel 210, the second grinding barrel 310 and the third grinding barrel 410 together.

[0104] The locking device of the utility model comprises a pull rod seat 509 arranged on the frame 5, and the frame 5, the third grinding barrel 410, the second grinding barrel 310, the first grinding barrel 210, and the upper cover 1 are respectively provided with corresponding fastening frames 505, and each fastening frame 505 is respectively provided with a tightening rod 506, and each tightening rod 506 is respectively provided with an inner rod 507 that can move up and down in the tightening rod 506, and the inner rod 507 is reset to the fixed position of the tightening rod 506 by a reset spring, and each inner rod 507 is provided with a card ball 508 at the sleeve end, and the inner side of the corresponding tightening rod 506 is provided with a groove corresponding to the card ball 508, and the tightening rod 500 corresponding to the third grinding barrel 410 is provided with a card ball 508. 6, one end of the tightening rod 506 corresponding to the frame 5, one end of the tightening rod 506 corresponding to the second grinding barrel 310 is sleeved on the other end of the tightening rod 506 corresponding to the third grinding barrel 410, one end of the tightening rod 506 corresponding to the first grinding barrel 210 is sleeved on the other end of the tightening rod 506 corresponding to the second grinding barrel 310, one end of the tightening rod 506 corresponding to the upper cover 1 is sleeved on the other end of the tightening rod 506 corresponding to the first grinding barrel 210, the other end of the tightening rod 506 corresponding to the upper cover 1 is fixed on the upper cover 1, and the other end of the inner rod 507 corresponding to the frame 5 is connected to the handle 510 on the pull rod seat 509 through a connecting rod.

[0105] When the handle 510 is operated, the inner rod 507 corresponding to the frame 5 is pushed upward by one end of the handle, and the other inner rods 507 move upward accordingly. Each locking ball 508 is pushed into the groove corresponding to each tightening rod 506, and the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 are locked together. When the handle 510 is operated in the reverse direction, each inner rod 507 is reset under the action of the reset spring, so that each locking ball 508 is reset and the locking device is unlocked.

[0106] For safety and locking effect, three sets of locking devices are installed on the frame 5 in this embodiment.

[0107] The workflow after the structure of this embodiment is integrated with that of the first embodiment, the second embodiment, and the third embodiment is as follows:

[0108] When working, first lock the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 together, as shown in the attached Figure 3 and attached Figure 4 As shown, the handles 510 on the frame 5 are operated sequentially, and the inner rod 507 corresponding to the frame 5 is pushed upward by one end of the handle 510, and the inner rod 507 corresponding to the third grinding barrel 410, the second grinding barrel 310, the first grinding barrel 210, and the upper cover 1 moves upward accordingly, and the corresponding locking balls 508 are pushed into the corresponding grooves of the tightening rods 506, thereby locking the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 and the frame 5 together. Restart the drive motor 501, and the motor shaft 502 of the drive motor 501 (the motor in this embodiment adopts a DC hub motor) drives the first movable grinding disc 203 of the first grinding device 2, the second movable grinding disc 303 of the second grinding device 3, and the third movable grinding disc 403 of the third grinding device 4 to rotate through the third coupling 405, the third main shaft 404, the second coupling 305, the second main shaft 304, the first coupling 205, and the first main shaft 204, thereby respectively putting the grinding components of the first grinding device 2, the second grinding device 3, and the third grinding device 4 into operation.

[0109] After grinding, when cleaning the refiner, first turn off the refiner power drive motor 501, and then open the locking device. Figure 4 As shown, the handles 510 on the frame 5 are operated sequentially. At this time, the inner rod 507 corresponding to the frame 5 is reset under the action of the reset spring, and the inner rods 507 corresponding to the third grinding barrel 410, the second grinding barrel 310, the first grinding barrel 210, and the upper cover 1 are also reset one by one under the action of the reset spring, and each locking ball 508 is pushed into the groove corresponding to each inner rod 507. In this way, the third grinding barrel 410, the second grinding barrel 310, the first grinding barrel 210, and the upper cover 1 are unlocked from each other and can be separated. Then, as shown in FIG. Figure 4 , Figure 5As shown, from top to bottom, the lifting power (the lifting motor 607 in this embodiment) on the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 respectively drives the corresponding lifting gear 608 to move, and the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 are lifted one by one along the lifting rack 606 on the column 6; from bottom to top, the lifting motor 607 on the third grinding barrel 410 first lowers the third grinding barrel 410 until the horizontal rotation of the third grinding barrel 410 is unobstructed, and then rotates it horizontally (that is, the third grinding barrel 410 rotates around the column 6 through the corresponding rotating sleeve 602) to leave the center position of the grinder; the same operation is performed, and then the second grinding barrel 310, the first grinding barrel 210 and the upper cover 1 are lowered and horizontally rotated one by one (that is, each grinding barrel and the upper cover 1 rotate around the column 6 through the corresponding rotating sleeves 602), and the balance of the pulping machine is maintained by changing the rotation direction and angle during rotation. In order to clean thoroughly, during cleaning, the grinding barrels and the upper cover 1 can be turned over one by one (i.e., each grinding barrel and the upper cover 1 rotate in the corresponding rotating sleeve 602 through the corresponding sleeve arm 603) and the upper cover 1, the first grinding barrel 210, the second grinding barrel 310, and the third grinding barrel 410 can be cleaned. After cleaning, from bottom to top, the third grinding barrel 410 is first rotated to the center position of the grinder, and then the lifting motor 607 on the third grinding barrel 410 lowers the third grinding barrel 410 to the working position. The same operation is performed to lower the second grinding barrel 310, the first grinding barrel 210, and the upper cover 1 to the working position one by one. When each grinding barrel is reset, since the first coupling 205, the second coupling 305, and the third coupling 405 adopt a blind connection automatic locking structure, it is convenient to realize the quick connection between the main shafts of each adjacent grinding barrel and between the third main shaft 404 and the motor shaft 502, and prevent the separation and damage between the transmission shafts of the grinding device. Then, the handles 510 on the frame 5 are operated in sequence to tighten the locking device, and the next refining work can be started.

[0110] The cleaning device is safe and efficient. Since the upper cover 1 and each grinding barrel can be separated, rotated and turned, the bean dregs remaining in the inner wall of each cone filter in the pulping machine can be cleaned thoroughly, the water consumption is less, and the deterioration and mildew caused by incomplete cleaning of the bean dregs can be effectively prevented.

[0116] Step a3, in the same operation as step a2, the grinders are lowered one by one and rotate horizontally around the column 6 through the second grinding barrel 310, the first grinding barrel 210 and the rotating sleeve 602 corresponding to the upper cover 1 to leave the center position of the grinder; during the rotation, the balance of the grinder is maintained by changing the rotation direction and angle;
