Description

Technical Field

[0001] The invention relates to the technical field of fermentation equipment, in particular to a wine fermentation tank. Background Art

[0002] The brewing process of liquor generally includes crushing, steaming, adding koji, fermentation, distillation, picking, blending, etc. The traditional liquor fermentation process is to ferment in a fermentation cellar, which is usually a pit dug in the ground as a fermentation cellar, which is highly dependent on the land.

[0003] With the development of winemaking technology, some production companies will use fermentation tanks as fermentation containers to ferment grains, which greatly reduces the dependence on land. Most of the existing fermentation tanks are made of stainless steel. There is a feed port on the top of the fermentation tank and a discharge port on the bottom. A stirring rod is installed in the fermentation tank. The stirring rod is driven by a motor to stir and mix the grains so that the grains can be evenly mixed and fermented. The fermentation tank is also equipped with a temperature control module to adjust the fermentation temperature. The fermentation tank is durable, has little pollution to grains, and is low in cost, and is generally welcomed by production companies.

[0004] However, the existing fermentation tanks also have some inconveniences in actual use. For example, the feed port of the fermentation tank is too small, which makes it inconvenient to clean the fermented material remaining on the inner wall of the fermentation tank, and it takes a certain amount of time to clean it up so as not to affect the next fermentation; the support rod of the fermentation tank's stirring rod does not stir evenly in the horizontal plane (because the grains are solid particles, it is difficult to stir the grains evenly when stirring with the support rod, and it is often necessary to extend the stirring time to improve the stirring uniformity, which is not conducive to reducing costs); the fermentation temperature distribution in the fermentation tank is uneven, resulting in uneven fermentation, and other problems. These problems have a certain impact on the winemaking efficiency and fermentation quality of the grains.

[0005] Based on this, the present application improves the existing fermentation tank to optimize the fermentation tank and make it more suitable for use by producers. Summary of the invention

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figures 1 to 8 The present invention provides a wine fermentation tank, comprising:

[0046] The tank body 1 has a truncated cone-shaped bottom, four legs are evenly and fixedly installed on the bottom of the tank body 1, a feed inlet 11 is arranged on the top of the tank body 1, a tank cover is installed on the feed inlet 11, a stirring rod 2 for stirring the material is arranged inside the tank body 1; a discharge port 12 is arranged in the middle of the bottom of the tank body 1;

[0047] A servo motor 3 is fixedly installed in the middle of the top of the tank body 1, and the output end of the servo motor 3 passes through the tank body 1 and is fixedly connected to the stirring rod 2;

[0048] A cleaning brush assembly is provided inside the tank body 1 for cleaning residual residues inside, and the servo motor 3 drives the cleaning brush assembly to move along the inner wall of the tank body 1;

[0049] The materials required for brewing are placed in the tank body 1 for fermentation. After fermentation, the required fermented product can be obtained, and the liquid of the fermented product in the tank body 1 is discharged through the discharge port 12. After opening the tank cover and taking out the fermented product, part of the fermented product will adhere to the inner wall of the tank body 1. These fermented products adhered to the inner wall of the tank body 1 are not easy to clean and need to be cleaned manually, which is not only time-consuming and labor-intensive, but also has only one opening on the top, which is very inconvenient to clean. If it is not cleaned thoroughly, it will affect the next fermentation. Therefore, the present invention provides a cleaning component, which only needs to be taken out manually. The fermented product adhered to the inner wall of the tank body 1 is driven by the servo motor 3 to operate the cleaning component, and the fermented product adhered to the inner wall of the tank body 1 is cleaned and discharged from the discharge port 12 through clean water, thereby avoiding the residual fermented product of the previous time on the inner wall of the tank body 1 before the next fermentation, which affects the fermented product of the next fermentation and fails to meet the standard, so as to ensure the stability of the quality of the fermented product.

[0050] The cleaning brush assembly includes a gear ring 4 installed on the upper end of the inner wall of the tank body 1, a connecting plate 5 is fixedly connected to the output end of the servo motor 3, a gear 6 is rotatably installed on the end of the connecting plate 5 away from the servo motor 3, the gear 6 is meshed with the gear ring 4, and a hollow shaft 61 extending outward along the axial direction is integrally provided at the center of the gear 6, the hollow shaft 61 is rotatably installed on the connecting plate 5, and a slot 62 is radially opened on the hollow shaft 61, and the slot 62 penetrates the hollow shaft 61 upward from the lower surface of the hollow shaft 61; a brush rod 7 The top of the brush rod 7 is inserted into the hollow shaft 61, and a protrusion 73 cooperating with the slot 62 is provided on the top of the brush rod 7, and the protrusion 73 is engaged in the slot 62. When the gear 6 is meshed with the gear ring 4 and rotates around the central axis of the tank body 1, the gear 6 rotates with the hollow shaft 61. Through the cooperation of the slot 62 and the protrusion 73, the hollow shaft 61 can rotate with the brush rod 7, and the bristles 75 fixed on the brush rod 7 clean the inner wall of the tank body 1 to remove the fermented matter adhered to the inner wall of the tank body 1;

[0051] The brush rod 7 includes a first rod body 71 and a second rod body 72, wherein the first rod body 71 corresponds to the straight tube portion 13 of the tank body 1, and the second rod body 72 corresponds to the truncated cone portion 14 of the tank body 1;

[0052] The transition section between the straight cylindrical part 13 and the truncated cone part 14 of the tank body 1 is provided with a slide rail 8, and the slide rail 8 is arranged along the circumference of the tank body 1; a slider 9 is slidably installed on the slide rail 8, and the slider 9 is rotatably installed at the bottom of the No. 1 rod body 71. When the No. 1 rod body 71 revolves around the inner wall of the tank body 1, the slider 9 can limit the bottom of the No. 1 rod body 71, so that the No. 1 rod body 71 remains stable during its revolution; the No. 2 rod body 72 is arranged parallel to the generatrix direction of the truncated cone part 14 of the tank body 1, and the top of the No. 2 rod body 72 is rotatably installed on the slider 9, and the top of the No. 2 rod body 72 is connected to the bottom end of the No. 1 rod body 71 through a flexible coupling 74. When the No. 1 rod body 71 rotates, the No. 2 rod body 72 can be driven to rotate through the flexible coupling 74. The sliding of the slider 9 can drive the No. 2 rod body 72 to revolve along the truncated cone part 14 of the tank body 1 to clean the truncated cone part 14.

[0053] During disassembly, first lift the brush rod 7 upward until the slider 9 is separated from the slide rail 8, then tilt the brush rod 7 toward the inner wall of the tank body 1, and then pull the brush rod 7 downward to allow the top of the brush rod 7 to separate from the hollow shaft 61, and the disassembly of the brush rod 7 is completed; when the brush rod 7 needs to be installed, the above disassembly process can be performed in the opposite direction.

[0054] As an embodiment of the present invention, a slideway 81 with a deep gap is provided on the top of the slide rail 8, and the slider 9 is provided with a U-shaped structure, and the side of the slider 9 is inserted into the slideway 81 and slides along the slideway 81; the slider 9 is an arc-shaped structure placed along the slide rail 8, and the slider 9 slides along the slide rail 8 by inserting the side into the slideway 81 of the slide rail 8, and the slider 9 is an arc-shaped structure with a certain length, so that when the brush rod 7 encounters the fermented material adhered to the inner wall of the tank body 1 and bends due to excessive resistance, the brush rod 7 gives the slider 9 a tendency to twist forward, and the slider 9 has a certain length along the sliding direction, which can offset the twisting of the slider 9 brought by the brush rod 7, and promote the sliding of the slider 9 under the drive of the brush rod 7, so that the brush rod 7 maintains a basically straight state, thereby improving the stability when cleaning the inner wall of the tank body 1;

[0055] A mounting seat 91 is provided on the side of the slider 9, and an opening for rotatably mounting the bottom of the No. 1 rod body 71 is provided on the top of the mounting seat 91, and the opening extends obliquely downward, and the direction in which the opening extends obliquely downward is parallel to the generatrix direction of the truncated cone portion 14 of the tank body 1, and the obliquely downward portion of the opening is an oblique opening, and a No. 2 rod body 72 parallel to the generatrix direction of the truncated cone portion 14 is rotatably mounted on the oblique opening, and a flexible coupling 74 is installed between the No. 2 rod body 72 and the No. 1 rod body 71, and the flexible coupling 74 is located in the opening; the power connection between the No. 1 rod body 71 and the No. 2 rod body 72 is achieved in the above manner;

[0056] The top of the inner ring side of the slide rail 8 is provided with an inclined surface 82, and the inclined surface 82 forms a contact line 83 with the inner ring side of the slide rail 8, and the contact line 83 contacts the groove bottom 92 of the U-shaped groove of the slider 9, and the side of the slider 9 does not contact the bottom of the slideway 81. This design method can reduce the contact area between the slide rail 8 and the slider 9 in the vertical direction, thereby reducing the contact area between the two, and then reducing the friction, so that the slider 9 slides more smoothly on the slide rail 8, and at the same time reduces the resistance of the No. 1 rod body 71, thereby reducing the bending deformation of the No. 1 rod body 71, and allowing the No. 1 rod body 71 to rotate more smoothly; the inclined surface 82 can form the contact line 83 on the one hand, and on the other hand can guide the slider 9 to enter the slideway 81, which is convenient for the installation of the brush rod 7;

[0057] The bottom of the slide 81 is provided with a discharge port 84 for discharging the fermented material falling into the slide 81 to avoid the fermented material from remaining in the tank body 1 .

[0058] A scraper 85 is provided below the slide rail 8, and the scraper 85 is used to clean the position below the slide rail 8 that cannot be cleaned by the bristles 75; the free end of the No. 2 rod body 72 is provided with a flange 721 extending radially outward, and the flange 721 is attached to the inner surface of the truncated cone portion 14 of the tank body 1, so that both ends of the No. 2 rod body 72 are supported to prevent the No. 2 rod body 72 from bending and sinking, and at the same time, the pressure at the connection between the No. 2 rod body 72 and the slider 9 is also reduced.

[0059] As an embodiment of the present invention, the gear 6 is connected to the connecting plate 5 through a joint bearing 51, and the lower surface of the gear ring 4 is provided with a limiting ring 41 fixed to the inner wall of the tank body 1, and the inner edge of the limiting ring 41 is inscribed in the center hole of the hollow shaft 61 of the gear 6; the connecting plate 5 is an elastic rod; the joint bearing 51 can provide a movable space for the movement of the gear 6 when installing and disassembling the brush rod 7, which is convenient for the installation and disassembly of the brush rod 7, and the upper surface of the limiting ring 41 is in contact with the lower surface of the gear 6. On the one hand, the limiting ring 41 can lift the gear 6 to reduce the wear of the joint bearing 51, and on the other hand, the connecting plate 5 presses the gear 6 to the limiting ring 41 so that the gear 6 slides along the upper surface of the limiting ring 41 to offset the torque brought to the gear 6 by the brush rod 7, so that when the gear 6 is meshed with the gear ring 4, the meshing force of the gear 6 and the gear ring 4 can be evenly distributed, thereby extending the service life of the gear 6 and the gear ring 4. The protrusion 73 is arranged on the top of the No. 1 rod body 71, and the diameter of the circle where the protrusion 73 is located is larger than the diameter of the center hole of the hollow shaft 61. The protrusion 73 is located above the limiting ring 41, and the limiting ring 41 limits the protrusion 73 to prevent the brush rod 7 from detaching from the hollow shaft 61 when it is bent by the resistance of the fermented material adhering to the inner wall of the tank body 1, so as to ensure the stability of the cleaning component.

[0060] As an embodiment of the present invention, the gear ring 4 is a multi-stage structure. The segmented design of the gear ring 4 allows the gear ring 4 to be installed or removed section by section from the feed port 11 during the installation and removal process of the gear ring 4, which is convenient and quick; the gear ring 4 is placed on the upper surface of the limiting ring 41 to form a complete circular ring, and a damping ring 42 is filled between the gear ring 4 and the tank body 1. On the one hand, the damping ring 42 is used to fill the gap between the gear ring 4 and the tank body 1, so that the outer wall of the gear ring 4 is pressed tightly to achieve radial limitation of the gear ring 4 to maintain the integrity of the gear ring 4 during operation; on the other hand, the damping ring 42 can maintain relative mobility between the gear ring 4 and the tank body 1. When normal cleaning is required, the thrust of the gear 6 received by the ring gear 4 is within the preset damping range to keep the ring gear 4 stationary. However, in the above method, the position of the ring gear 4 is fixed, so that the motion trajectory of the gear 6 is fixed, and the gear 6 must both revolve and rotate, which will cause the cleaning position of the brush cloth 752 to be fixed, and it is easy to have a cleaning dead angle. For this reason, the thrust of the gear 6 received by the ring gear 4 can be greater than the preset damping, and the ring gear 4 will slide relative to the tank body 1 and rotate in the direction of the revolution of the gear 6, so that the position of the ring gear 4 changes, thereby changing the motion trajectory of the gear 6, and then adjusting the cleaning position of the brush cloth 752 to achieve a better cleaning effect. The method of changing the position of the ring gear 4 can be manually adjusted through the feed port 11, or by increasing the speed of the servo motor 3 to increase the acceleration of the gear 6, and the ring gear 4 is driven to rotate by the force of the gear 6 acting on the ring gear 4 during acceleration being greater than the preset damping of the damping ring 42. This method can achieve position adjustment during the working process of the ring gear 4, which is more convenient.

[0061] As an embodiment of the present invention, the bristles 75 include a brush cover 751 and a brush cloth 752. The brush cover 751 is sleeved on the outside of the No. 1 rod body 71 and the No. 2 rod body 72 and fixed together, so that the No. 1 rod body 71 and the No. 2 rod body 72 can rotate with the brush cover 751, and the brush cloth 752 is sewn at intervals on the outside of the brush cloth 752. The brush cover 751 and the brush cloth 752 are both made of flexible and wear-resistant cloth. The brush cover 751 can rotate with the brush cloth 752 when rotating. The brush cloth 752 can be lifted from a drooping state to a horizontal state under the action of increasing centrifugal force. By controlling the speed of gear 6, that is, the size of the centrifugal force of the brush cloth 752, the angle at which the brush cloth 752 is lifted upward can be adjusted, thereby adjusting the impact force and friction force of the brush cloth 752 on the inner wall of the tank body 1 to meet the cleaning needs of the inner wall of the tank body 1 in different conditions. When the brush cloth 752 is cleaning, the fermented material brought down by the brush cloth 752 can be thrown out under the action of centrifugal force to achieve the recovery of the fermented material and the self-cleaning of the brush cloth 752. Before cleaning, the brush cloth 752 can be soaked in advance to increase the weight of the brush cloth 752, thereby increasing the centrifugal force to improve the cleaning effect.

[0062] The design of the brush cloth 752 of the present invention uses centrifugal force to lift the soft brush cloth 752 to clean the inside of the tank body 1. On the one hand, compared with the use of bristles 75, it can reduce the scratches on the inner wall of the tank body 1. On the other hand, it can prevent the fermented material from transmitting resistance to the No. 1 rod body 71 through the brush cloth 752 and affecting the normal revolution and rotation of the No. 1 rod body 71. In addition, the softness of the brush cloth 752 facilitates the installation and disassembly of the brush rod 7, achieving multiple goals at one stroke.

[0063] As an embodiment of the present invention, a through hole 753 is provided on the brush cloth 752, and the through hole 753 is sealed by flame to prevent the wire of the brush cloth 752 from loosening and falling off during operation. The through hole 753 can increase the friction of the brush cloth 752 on the fermented material, and the fermented material can be scraped off the inner wall of the tank body 1 through the through hole 753, which can significantly improve the cleaning effect of the fermented material.

[0064] As an embodiment of the present invention, the stirring rod 2 includes a vertically arranged main rod 21, and the side wall of the main rod 21 is welded with a plurality of staggered side panels 22, and the side panels 22 are arranged tilted compared to the horizontal plane, so that when the side panels 22 rotate with the main rod 21, the side panels 22 can flip the fermented material upward to improve the uniformity of stirring the fermented material; the bottom edge of the side panel 22 is provided with a short side 23 in the direction opposite to the rotation direction, and an angle is formed between the short side 23 and the side panel 22, and a ceramic heating rod 24 is installed at the angle, and the ceramic heating rod 24 is electrically connected to the controller, and the ceramic heating rod 24 is used to heat the fermented material during the fermentation process. The placement position of the ceramic heating rod 24 can avoid being broken by the resistance of the fermented material when the side panel 22 rotates, so as to protect the ceramic heating rod 24.

[0065] As an embodiment of the present invention, the side panel 22 is made of aluminum, and the angled portion of the side panel 22 fits with the ceramic heating rod 24, so that the heat of the ceramic heating rod 24 is rapidly diffused through the side panel 22 to improve the heating efficiency of the fermented material during fermentation; a plurality of contact grooves 25 are provided on the upper surface of the side panel 22, which can not only increase the contact area with the fermented material and improve the heating efficiency, but also make the fermented material on the same plane displaced in the vertical direction after passing through the side panel 22 to improve the stirring effect.

[0066] As an embodiment of the present invention, the contact groove 25 is arranged on the side plate 22 to be inclined outward, so that when the side plate 22 rotates, the fermented material located on the inside is pushed outward, so as to achieve mixing and stirring of the fermented material in the radial direction of the tank body 1, so as to improve the uniformity and sufficiency of the fermentation of the fermented material; the bottom of the contact groove 25 is an arc-shaped structure, and the design of the bottom structure of the contact groove 25 can avoid the side plate 22 from bending or breaking due to the weak bottom structure of the contact groove 25, and avoid the side plate 22 from bending and deforming when rotating; on the other hand, the arc-shaped bottom of the contact groove 25 is conducive to the flow of the fermented material, and avoids the situation where the fermented material remains at the bottom of the contact groove 25 and is inconvenient to clean.

[0067] During operation, grains and yeast are added into the tank body 1 through the feed port 11, and then the servo motor 3 is started to drive the stirring rod 2 to mix the grains and yeast to form a mixed material, and at the same time, the ceramic heating rod 24 is energized to heat the mixed material. After the mixing is completed, the fermentation process can be carried out. During the fermentation process, the ceramic heating rod 24 can be used to keep the tank body 1 at a constant fermentation temperature, and the stirring rod 2 can be used to continuously stir, so as to improve the fermentation efficiency and fermentation uniformity.

[0068] When cleaning the tank body 1, assemble the brush rod 7 in advance, then put the brush rod 7 into the feed port 11, first insert the No. 1 rod body 71 into the hollow shaft 61 of the gear 6, then lift the connecting plate 5 upwards, and place the slider 9 into the slide rail 8 to install the brush rod 7.
