Description

Technical Field

[0001] The present invention relates to the technical field of wine mashing, and specifically relates to a mashing device for wine production, and also relates to a mashing method for a mashing device for wine production. Background Art

[0002] In the process of wine production, the mashing of grapes is a crucial step, which directly affects the extraction efficiency of juice, the quality of juice, and the taste and flavor of the final wine during the subsequent fermentation process. After the grapes are mashed, it is necessary to separate the pulp and juice, but the pulp will block the discharge port of the separated mixture, affecting the mashing efficiency of the device for grapes.

[0003] The grape mashing device disclosed in the patent with the publication number CN222574603U screens the mashed pulp through a filtering rod, and performs a further picking operation on the pulp screened by the filtering rod through a picking rod, and then discharges the pulp out of the interior of the mashing bin through a discharge door. The juice produced by mashing is collected through a collection tank, thereby avoiding the blockage of the device caused by the mashed pulp, and thus improving the mashing efficiency of the device for grapes and improving the practicality.

[0004] Although the above solution realizes the treatment of the pulp in the gaps between adjacent filtering rods, for the pulp on the filtering rod that does not exceed the range of the filtering rod, the picking rod cannot pick out this part of the pulp. When the filtering rod rotates to the vertical downward position, the pulp may still fall into the juice, and some pulp may adhere to the filtering rod for a long time, resulting in the pollution of the filtering rod. When the juice passes through the contaminated filtering rod again, the juice will also be polluted. Summary of the Invention

By setting a main shaft, an outer housing, a filter screen, a flipping connection structure, a separation pipe, a first cleaning structure, a second cleaning structure, and a sterilization structure, the efficient cleaning of the pulp attached to the surface of the filter screen is realized, and the pollution of the juice by the pulp attached to the filter screen is avoided.

[0006] In order to solve the problems of the prior art, the present invention provides a crushing device for wine production, comprising a crushing mechanism and a separation mechanism arranged at the lower end of the crushing mechanism, the separation mechanism comprising a vertically arranged main shaft and a separation unit arranged on the main shaft, the separation unit comprising an outer cover body covered outside the main shaft, a filter screen and a flip connection structure; the interior of the outer cover body is provided with four stations of separation, first cleaning, second cleaning and sterilization in sequence around the main shaft, and the four stations are respectively provided with a separation pipeline, a first cleaning structure, a second cleaning structure and a sterilization structure; the filter screen is located inside the separation pipeline at the level of the separation station; the flip connection structure connects the main shaft with the filter screen, and the flip connection structure changes the state of the filter screen following the rotation of the main shaft, so that the posture of the filter screen at each station is different.

[0007] Preferably, there are at least four separation units, and the filter screens in the four separation units are located in four different working positions.

[0008] Preferably, the flip connection structure includes a rotating shaft and a flip structure; one end of the rotating shaft passes through the main shaft vertically, and the axis of the rotating shaft intersects with the axis of the main shaft, and the other end of the main shaft is connected to the filter screen; the flip structure is arranged on one side of the rotating shaft, and the flip structure is used to drive the rotating shaft to rotate around its own axis.

[0009] Preferably, the flipping structure includes a horizontally arranged active intermittent gear and a vertically arranged driven intermittent gear; the active intermittent gear is coaxial with the main shaft and fixedly connected; the driven intermittent gear is coaxial with the rotating shaft and fixedly connected, and the driven intermittent gear is intermittently meshed with the active intermittent gear.

[0010] Preferably, the flipping structure also includes a toggle assembly, which includes a baffle rod parallel to the rotating shaft and a toggle plate connected to the active intermittent gear; one end of the baffle rod is connected to the driven intermittent gear, and the other end of the baffle rod extends toward the middle of the active intermittent gear; the toggle plate rotates around the axis of the main shaft following the active intermittent gear.

[0011] Preferably, the toggle assembly also includes a connecting seat and a reset rod; the connecting seat is connected to the active intermittent gear; one end of the reset rod is axially connected to the toggle plate, the other end of the reset rod passes through the connecting seat, the other end of the reset rod is sleeved with a first reset spring, and the two ends of the first reset spring are respectively abutted against the end of the connecting seat and the reset rod.

[0012] Preferably, the flip connection structure further includes a horizontal stabilizing structure, which includes a rectangular docking assembly arranged at one end of the rotating shaft and a horizontally arranged stabilizing plate.

[0013] Preferably, the rectangular docking assembly includes a mounting plate and at least four rollers; the mounting plate is connected to the end of the rotating shaft; the four rollers are all arranged parallel to the rotating shaft, and the four rollers are installed on the mounting plate in a matrix shape.

[0014] Preferably, the horizontal stability structure further includes an adaptive downward pressure assisting component, which is connected to the stabilizing plate and is used to apply a downward force along the main shaft to the stabilizing plate.

[0015] A mashing method for a wine production mashing device, which is applied to a wine production mashing device, includes the following steps: S1. After the grape is mashed by the mashing mechanism, the pulp and juice fall into the separation mechanism; S2. Inside the separation mechanism, the pulp and juice fall along the separation pipeline onto the filter screen. The pulp remains on the filter screen, and the juice continues to flow downward; S3. When the pulp carried by the filter screen affects filtration, the main shaft rotates. The main shaft drives the filter screen to rotate synchronously around the axis of the main shaft through the flipping connection structure.

The combination of the separation pipeline and the filter screen realizes the separation of the pulp and the juice, ensuring the purity of the juice. The flipping connection structure enables the filter screen to automatically adjust its posture according to the rotation of the main shaft. The conversion of the filter screen from horizontal to vertical and then to horizontal not only avoids the obstruction of the movement of the pulp during the cleaning process of the filter screen, but also makes the side with attached pulp face downward by changing the direction of the filter screen, greatly improving the working efficiency and quality of the second cleaning structure. After the cleaning is completed, the filter screen is rotated to the sterilization station, and the sterilization structure performs a comprehensive sterilization treatment on both surfaces of the filter screen, effectively eliminating possible microbial contamination and ensuring the hygiene standard of subsequent separation operations. By controlling the filter screen to switch postures in different stations through the flipping connection structure, the filter screen can contact the first cleaning structure and the second cleaning structure in a posture that is more convenient for cleaning the pulp, thereby realizing the efficient cleaning of the pulp attached to the surface of the filter screen and avoiding the contamination of the juice by the pulp attached to the filter screen.

[0017] 2. The present invention is provided with at least four separation units, and ensures that the filter screens of the four separation units are respectively in different working states. During the rotation of the main shaft, at least one filter screen is always in the separation position, thereby realizing continuous separation of the mixture and avoiding efficiency loss caused by waiting for the filter screen to return to the separation position.

[0018] 3. The cooperation of the rotating shaft and the flipping structure of the present invention realizes the flipping of the filter during the rotation process, so that the filter can enter the first cleaning station and the second cleaning station respectively in a posture adapted to the first cleaning structure and the second cleaning structure, thereby realizing the flipping cleaning of the filter and significantly improving the cleaning efficiency and cleanliness.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figures 1 to 10 As shown: A crushing device for wine production, including a crushing mechanism and a separation mechanism arranged at the lower end of the crushing mechanism, the separation mechanism includes a vertically arranged main shaft 1 and a separation unit arranged on the main shaft 1, the separation unit includes an outer cover body 2 covered outside the main shaft 1, a filter screen 3 and a flip connection structure 4; the interior of the outer cover body 2 is sequentially provided with four stations of separation, first cleaning, second cleaning and sterilization around the main shaft 1, and the four stations are respectively provided with a separation pipe 5, a first cleaning structure 6, a second cleaning structure 7 and a sterilization structure 8; the filter screen 3 is located inside the separation pipe 5 at the level of the separation station; the flip connection structure 4 connects the main shaft 1 with the filter screen 3, and the flip connection structure 4 changes the state of the filter screen 3 following the rotation of the main shaft 1, so that the posture of the filter screen 3 at each station is different.

[0032] The separation pipe 5, the first cleaning structure 6, the second cleaning structure 7 and the sterilization structure 8 are all prior arts. After the grape smashing mechanism smashes the grapes, the pulp and juice fall into the separation mechanism under the action of gravity. Inside the separation mechanism, the pulp and juice fall along the separation pipe 5 onto the filter screen 3. The pulp is blocked by the filter screen 3 and remains on the horizontal filter screen 3, while the juice passes through the filter screen 3 and continues to flow downward, achieving the separation of the pulp and the juice. When the filter screen 3 bears more pulp, the main shaft 1 starts to rotate. The main shaft 1 drives the filter screen 3 to rotate synchronously around the axis of the main shaft 1 through the flipping connection structure 4. At the same time, during the process of the filter screen 3 rotating to the first cleaning station, the flipping connection structure 4 gradually changes the filter screen 3 from a horizontal state to a vertical state. At this time, the filter screen 3 does not hinder the movement of the pulp, and the pulp falls from the filter screen 3 under the action of gravity, achieving the preliminary cleaning of the filter screen 3. Then the main shaft 1 continues to rotate, and the filter screen 3 rotates to the second cleaning station. At this time, the flipping connection structure 4 gradually changes the filter screen 3 from a vertical state to a horizontal state, and the two rotation directions of the filter screen 3 are the same, making the side of the filter screen 3 that originally carried the pulp face downward, facilitating the second cleaning structure 7 to deeply clean the pulp attached to the filter screen 3. The main shaft 1 rotates again, and the main shaft 1 drives the filter screen 3 to rotate horizontally to the sterilization station, and the sterilization structure 8 sterilizes the two surfaces of the filter screen 3. Finally, the main shaft 1 drives the filter screen 3 to rotate back to the separation station to prepare for a new round of separation operation, thereby achieving the efficient cleaning of the pulp attached to the surface of the filter screen 3 and preventing the pulp from attaching to the filter screen 3 and contaminating the juice.

[0033] Refer to Figure 2 and Figure 3 shown in the figure: There are at least four separation units, and the filter screens 3 in the four separation units are in four different stations.

[0034] If the number of separation units is set to be less than four, it will lead to an increase in the waiting time of the filtering process. Specifically, when there is only one separation unit in the separation mechanism, the separation pipe 5 needs to wait for the filter net 3 to go through three different working positions before the filter net 3 can return to the separation pipe 5. If the number of separation units is two, the separation pipe 5 needs to wait for the filter net 3 to go through two working positions to make the filter net 3 return to the separation pipe 5. When the number of separation units is three, the separation pipe 5 needs to wait for the filter net 3 to go through one working position to make the filter net 3 return to the separation pipe 5. In the case where there is no blockage of the filter net 3 in the separation pipe 5, the mashed pulp and juice mixture will fall directly. To ensure that the mixture can be continuously blocked by the filter net 3, the separation mechanism needs to be configured with at least four separation units, and the filter nets 3 of these four separation units are in different working states respectively. As the main shaft 1 rotates, these four filter nets 3 will rotate synchronously with the main shaft 1, realizing the synchronous transformation of the states of the four filter nets 3. By configuring at least four separation units, it is ensured that during the rotation of the main shaft 1, at least one filter net 3 is always in the separation station, thus realizing the continuous separation of the mixture and avoiding the efficiency loss caused by waiting for the filter net 3 to return to the separation station.

[0035] Refer to Figure 3 and Figure 5 shown in: The flipping connection structure 4 includes a rotating shaft 41 and a flipping structure 42; one end of the rotating shaft 41 vertically passes through the main shaft 1, and the axis of the rotating shaft 41 intersects with the axis of the main shaft 1, and the other end of the main shaft 1 is connected to the filter net 3; the flipping structure 42 is arranged on one side of the rotating shaft 41, and the flipping structure 42 is used to drive the rotating shaft 41 to rotate around its own axis.

[0036] If the filter screen 3 only rotates around the axis of the main shaft 1 following the main shaft 1, the side of the filter screen 3 for carrying the pulp always faces a certain direction. When cleaning the side of the filter screen 3 for carrying the pulp, the surface of the filter screen 3 will always impede the movement of the pulp, making it inconvenient to clean the filter screen 3 thoroughly. Therefore, a rotating shaft 41 and a flipping structure 42 are provided. When the main shaft 1 rotates, the flipping structure 42 drives the rotating shaft 41 to rotate, and the flipping structure 42 controls the rotation speed of the rotating shaft 41. When the main shaft 1 rotates 90 degrees, the filter screen 3 moves to the first cleaning station. At this time, the flipping structure 42 drives the rotating shaft 41 to rotate 90 degrees, and the rotating shaft 41 drives the filter screen 3 to flip 90 degrees, so that the filter screen 3 changes from a horizontal state to a vertical state. Then the main shaft 1 rotates 90 degrees for the second time, and the filter screen 3 moves to the second cleaning station. At this time, the flipping structure 42 drives the rotating shaft 41 to continue rotating 90 degrees, and the rotating shaft 41 drives the filter screen 3 to change from a vertical state to a horizontal state. At this time, the surface of the side of the filter screen 3 that originally carried the pulp faces downward. Then the main shaft 1 rotates 90 degrees for the third time, and the flipping structure 42 stops driving the rotating shaft 41 to rotate, so that the filter screen 3 moves to the sterilization structure 8 in a horizontal posture. After sterilization, the main shaft 1 rotates 90 degrees for the fourth time. At this time, the flipping structure 42 drives the rotating shaft 41 to rotate 180 degrees, flipping the side of the filter screen 3 for carrying the pulp upward, so that the filter screen 3 re-enters the separation pipe 5, thus realizing the flipping and cleaning of the filter screen 3, significantly improving the cleaning efficiency and cleanliness.

[0037] Refer to Figure 5 and Figure 6 As shown: The flipping structure 42 includes a horizontally arranged active intermittent gear 421 and a vertically arranged driven intermittent gear 422; the active intermittent gear 421 is coaxially and fixedly connected with the main shaft 1; the driven intermittent gear 422 is coaxially and fixedly connected with the rotating shaft 41, and the driven intermittent gear 422 is intermittently engaged with the active intermittent gear 421.

[0038] When the main shaft 1 rotates, the main shaft 1 drives the active intermittent gear 421 to rotate, the active intermittent gear 421 drives the driven intermittent gear 422 to rotate, and the driven intermittent gear 422 drives the rotating shaft 41 to rotate. When the main shaft 1 rotates 90 degrees for the first time, the active intermittent gear 421 meshes with the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the second time, the active intermittent gear 421 meshes with the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the third time, the active intermittent gear 421 is separated from the driven intermittent gear 422. When the main shaft 1 rotates 90 degrees for the fourth time, the active intermittent gear 421 meshes with the driven intermittent gear 422. When rotating 90 degrees three times, the active intermittent gear 421 and the driven intermittent gear 422 are moved so that the rotating shaft 41 does not rotate during this process, so that the filter screen 3 can enter the sterilization structure 8 horizontally, effectively avoiding the problem of large vertical space occupation caused by the filter screen 3 vertically entering the sterilization structure 8, and also eliminating the need for the sterilization structure 8 to use an additional drive to move and cover the filter screen 3. Through the cooperation of the active intermittent gear 421 and the driven intermittent gear 422, the rotational movement of the main shaft 1 is linked with the rotational movement of the rotating shaft 41, without the need to configure an additional drive device to drive the rotating shaft 41 separately, thereby realizing the linkage mechanism between the main shaft 1 and the rotating shaft 41.

[0039] Reference Figure 6 and Figure 7 As shown: the flip structure 42 also includes a toggle assembly 423, which includes a baffle 4231 parallel to the rotating shaft 41 and a toggle plate 4232 connected to the active intermittent gear 421; one end of the baffle 4231 is connected to the driven intermittent gear 422, and the other end of the baffle 4231 extends to the middle of the active intermittent gear 421; the toggle plate 4232 rotates around the axis of the main shaft 1 following the active intermittent gear 421.

[0040] In the process of the main shaft 1 driving the active intermittent gear 421 to rotate, the active intermittent gear 421 needs to drive the driven intermittent gear 422 to complete two 90-degree rotations, a 0-degree stop and a 180-degree rotation in a specific order. In particular, in the stage of driving the driven intermittent gear 422 to rotate 180 degrees, the active intermittent gear 421 itself only rotates 90 degrees, which is not enough to directly complete the action. Therefore, it is necessary to use the toggle assembly 423 to achieve supplementary drive. When the filter screen 3 is horizontally placed inside the sterilization structure 8, the toggle plate 4232 rotates with the active intermittent gear 421. When the main shaft 1 completes the third 90-degree rotation and is ready for the fourth rotation, the toggle plate 423 2 gradually approaches the stopper 4231. When the main shaft 1 starts to rotate 90 degrees for the fourth time, the toggle plate 4232 contacts the stopper 4231 and applies a driving force along its tangential direction to the driven intermittent gear 422 through the stopper 4231. This driving force prompts the driven intermittent gear 422 to rotate 90 degrees independently first. At this time, the active intermittent gear 421 re-engages with the driven intermittent gear 422 that has rotated 90 degrees. Subsequently, the active intermittent gear 421 continues to rotate the remaining 90 degrees, driving the driven intermittent gear 422 to complete the remaining 90 degrees. Therefore, in the whole process of the main shaft 1 rotating 90 degrees for the fourth time, the driven intermittent gear 422 is rotated 180 degrees in total.

[0041] Reference Figure 6 and Figure 7 As shown: the toggle assembly 423 also includes a connecting seat 4233 and a reset rod 4234; the connecting seat 4233 is connected to the active intermittent gear 421, and the toggle plate 4232 is hinged to the connecting seat 4233; one end of the reset rod 4234 is axially connected to the toggle plate 4232, and the other end of the reset rod 4234 passes through the connecting seat 4233, and the other end of the reset rod 4234 is sleeved with a first reset spring 4235, and the two ends of the first reset spring 4235 are respectively abutted against the end of the connecting seat 4233 and the reset rod 4234.

[0042] When the toggle plate 4232 pushes the shift lever 4231 to move, the shift lever 4231 not only moves in the tangential direction of rotation towards the toggle plate 4232, but also moves along the toggle plate 4232 away from the driving intermittent gear 421. If the toggle plate 4232 is fixedly connected to the driving intermittent gear 421, the movement of the toggle plate 4232 and the shift lever 4231 may interfere with each other, affecting the movement of the shift lever 4231. By providing a connecting seat 4233 and a reset lever 4234, and sleeving a first reset spring 4235 on the reset lever 4234, the reaction force exerted by the shift lever 4231 on the toggle plate 4232 will cause the toggle plate 4232 to rotate around its hinge joint with the connecting seat 4233, reducing the interference of the toggle plate 4232 on the shift lever 4231. At the same time, when the toggle plate 4232 rotates, it drives the relative movement between the reset lever 4234 and the connecting seat 4233. The connecting seat 4233 compresses the first reset spring 4235, and the first reset spring 4235 stores elastic potential energy. When the toggle plate 4232 and the shift lever 4231 are disengaged from contact, the first reset spring 4235 releases the elastic potential energy, and the elastic potential energy acts on the reset lever 4234 to pull the toggle plate 4232 back to its original position. Through the movement of the toggle plate 4232, the interference of the toggle plate 4232 on the movement of the shift lever 4231 is effectively reduced, ensuring that the shift lever 4231 and the driven intermittent gear 422 connected thereto can achieve smoother and more stable rotation.

[0043] Refer to Figure 3 and Figure 8 As shown: The flipping connection structure 4 further includes a horizontal stabilizing structure 43. The horizontal stabilizing structure 43 includes a rectangular docking component 431 provided at one end of the rotating shaft 41 and a horizontally arranged stabilizing plate 432.

[0044] When the main shaft 1 makes the third 90-degree rotation, the driving intermittent gear 421 and the driven intermittent gear 422 are not engaged. Since the vibration generated by the rotation of the main shaft 1 is transmitted to the rotating shaft 41, the rotating shaft 41 may still rotate. Therefore, a rectangular docking component 431 and a horizontal stabilizing plate 432 are provided. The rectangular docking component 431 has four consecutive surfaces. When the rotating shaft 41 rotates, the rotating shaft 41 drives the rectangular docking component 431 to rotate, and the four consecutive surfaces on the rectangular docking component 431 are sequentially rotated to face horizontally upward. The horizontally arranged stabilizing plate 432 contacts the surface of the rectangular docking component 431. Since there is a large overlapping area between the surface of the rectangular docking component 431 and the stabilizing plate 432, the vibration force acting on the rotating shaft 41 is restricted by the contact between the stabilizing plate 432 and the rectangular docking component 431, ensuring that the filter net 3 can maintain a stable posture during the horizontal displacement process and avoiding the occurrence of deflection phenomena.

[0045] Refer to Figure 8 and Figure 9As shown: The rectangular docking component 431 includes a mounting plate 4311 and at least four rollers 4312; the mounting plate 4311 is connected to the end of the rotating shaft 41; the four rollers 4312 are all arranged parallel to the rotating shaft 41, and the four rollers 4312 are mounted on the mounting plate 4311 in a matrix.

[0046] If the rectangular docking component 431 is a quadrangular prism, then when the rectangular docking component 431 rotates following the rotating shaft 41, the edges of the rectangular docking component 431 will come into contact with the stabilizing plate 432, and sliding friction will occur between the two. Moreover, the contact area between the two is small, resulting in a large frictional force between the two. During the long-term rotation of the rectangular docking component 431, both the rectangular docking component 431 and the stabilizing plate 432 will be worn. Therefore, at least four rollers 4312 are provided, and the four rollers 4312 are mounted on the mounting plate 4311 in a matrix. When the stabilizing plate 432 comes into contact with one of the rollers 4312, the force exerted by the stabilizing plate 432 on this roller 4312 will be transmitted to the rotating shaft 41 through the mounting plate 4311, causing the rotating shaft 41 to rotate. At the same time, another roller 4312 on the mounting plate 4311 will move towards the stabilizing plate 432 and finally come into contact with the stabilizing plate 432. At this time, two rollers 4312 are in contact with the stabilizing plate 432 simultaneously, such that both sides of the rotating shaft 41 are subjected to forces that are equal in magnitude and the same in direction. Therefore, the rotating shaft 41 will not rotate. When the main shaft 1 drives the rotating shaft 41 to rotate, rolling friction occurs between the roller 4312 and the stabilizing plate 432. The coefficient of rolling friction is small, and the contact area between the roller 4312 and the stabilizing plate 432 is large, making the frictional force between the roller 4312 and the stabilizing plate 432 small, thereby avoiding wear of the rectangular docking component 431 and the stabilizing plate 432.

[0047] Refer to Figure 8 and Figure 10 As shown: The horizontal stabilizing structure 43 further includes an adaptive downward pressure assisting component 433. The adaptive downward pressure assisting component 433 is connected to the stabilizing plate 432, and the adaptive downward pressure assisting component 433 is used to apply a downward force along the main shaft 1 to the stabilizing plate 432.

[0048] Specifically, the adaptive downward pressure assisting component 433 includes a connecting plate 4331 and at least two connecting rods 4332. The connecting plate 4331 is fixedly connected to the main shaft 1, and the connecting plate 4331 is parallel to the stabilizing plate 432. The two connecting rods 4332 are both slidably connected perpendicular to the connecting plate 4331, and one end of the connecting rod 4332 is connected to the stabilizing plate 432. A second return spring 4333 is sleeved on both of the connecting rods 4332, and the two ends of the second return spring 4333 are respectively connected to the connecting plate 4331 and the stabilizing plate 432.

[0049] When the stabilizing plate 432 contacts the two rollers 4312, the distance between the stabilizing plate 432 and the axis of the rotating shaft 41 is the shortest. When the rotating shaft 41 drives the rectangular docking assembly 431 to rotate, the roller 4312 will apply an upward acting force along the axis direction of the main shaft 1 to the stabilizing plate 432, causing the stabilizing plate 432 to move away from the rotating shaft 41. At this time, the stabilizing plate 432 pushes the connecting rod 4332 to slide relative to the connecting plate 4331, and the second return spring 4333 is compressed. When the line connecting the rotating shaft 41 and the roller 4312 is perpendicular to the stabilizing plate 432, the distance between the stabilizing plate 432 and the rotating shaft 41 is the largest. Then the roller 4312 continues to rotate around the axis of the rotating shaft 41. At this time, the stabilizing plate 432 moves towards the rotating shaft 41 under the pushing action of the second return spring 4333 until the stabilizing plate 432 contacts the two rollers 4312 again. And the second return spring 4333 continuously applies a downward acting force along the axis direction of the main shaft 1 to the stabilizing plate 432. Therefore, after the rotating shaft 41 rotates 90 degrees, the stabilizing plate 432 can timely prevent the rotating shaft 41 from continuing to rotate, so that the filter plate can accurately stay at each working position in the corresponding posture.

[0050] A mashing method for a mashing device used in wine production, which is applied to a mashing device used in wine production, includes the following steps: S1. After the mashing mechanism mashes the grapes, the pulp and juice drop into the separation mechanism; S2. Inside the separation mechanism, the pulp and juice flow along the separation pipeline 5 onto the filter screen 3. The pulp remains on the filter screen 3, and the juice continues to flow downward; S3. When the filter screen 3 bears a large amount of pulp (when the pulp affects filtration), the main shaft 1 rotates. The main shaft 1 drives the filter screen 3 to rotate synchronously around the axis of the main shaft 1 through the flipping connection structure 4. At the same time, when the filter screen 3 rotates to the first cleaning position, the flipping connection structure 4 flips the filter screen 3 by 90 degrees for preliminary cleaning at the first cleaning position; S4. Then the main shaft 1 continues to rotate, and the filter screen 3 rotates to the second cleaning position. At this time, the flipping connection structure 4 flips the filter screen 3 by 90 degrees again for secondary cleaning at the second cleaning position; S5. The main shaft 1 rotates again, and the filter screen 3 rotates to the sterilization position to sterilize the filter screen 3. Finally, the filter screen 3 rotates back to the separation position.
