[0027] EMBODIMENT

[0028] The vertical wine brewing raw material pretreatment system comprises a wetting device for wetting the wine brewing raw material and a feeding device for continuously feeding into the wetting device. The wetting device comprises a shell 5 with open ends and a central column 12 coaxially arranged in the shell 5. The shell 5 is in the shape of a circular truncated cone with the diameter of the lower end being larger than that of the upper end. The top end of the shell 5 is provided with a cylindrical extension upward. The cylindrical extension is connected with the feeding device. The central column 12 is in the shape of a cylinder and its axis is coincident with the axis of the shell 5. In this embodiment, the diameter of the central column 12 is equal to that of the top end of the shell 5 and the top end surface of the central column 12 is below the top end surface of the shell 5. The central column 12 and the inner side wall of the shell 5 form a wetting channel 502 for the wine brewing raw material to flow through. The width of the wetting channel 502 gradually increases from top to bottom along the height direction of the shell 5. The shell 5 is provided with a plurality of water inlet holes 501 for spraying water droplets into the wetting channel 502. The external water supply equipment sprays water droplets into the wetting channel 502 through the water inlet holes 501. The wine brewing raw material enters through the upper end opening of the shell 5. The wine brewing raw material after entering first collides with the upper end surface of the central column 12, splashes and falls into the wetting channel 502, and contacts and mixes with the water droplets, thereby realizing the conditioning and wetting of the wine brewing raw material. The collision of the wine brewing raw material with the central column 12 can scatter the wine brewing raw material, which facilitates the contact of the wine brewing raw material with the water droplets, improves the mixing effect of the wine brewing raw material with the water droplets, and further improves the wetting effect of the wine brewing raw material, so that the wetting is more uniform, and finally, the wine quality and the wine efficiency of the wine brewing raw material are improved.

[0029] In this embodiment, the upper end surface of the central column 12 is an arc surface convex upward, so that the wine brewing raw material splashes in different directions after falling on the upper end surface.

[0030] The water inlet holes 501 are further limited. In this embodiment, the number of the water inlet holes 501 is five and the distance between each water inlet hole 501 and the top end of the shell 5 is the same. The water inlet holes 501 are uniformly and circumferentially distributed along the shell 5. The water inlet holes 501 are located near the top of the wetting channel 502 and below the upper end surface of the central column 12, so as to ensure that the water droplets are sprayed on the splashing wine brewing raw material. The acute angle between the axis of the water inlet hole 501 and the vertical direction is 58-65°, and the included angle between the axis of the water inlet hole 501 and the tangent of the shell 5 at this position is 86-94°, so that the water droplets and the flow direction with an included angle of 25-32° with the horizontal direction enter the wetting channel 502 and impact the wine brewing raw material, and then the water droplets and the wine brewing raw material form a mixing area in the wetting channel 502. The water droplets have a velocity component in the tangent direction. After the water droplets contact and mix with the wine brewing raw material, the water droplets and the wine brewing raw material move in a spiral shape in the wetting channel 502, which enhances the turbulent degree of the water droplets and the wine brewing raw material, and further makes the wetting of the wine brewing raw material more uniform. If the water inlet holes 501 are not arranged along the radial direction, the inclined directions of the five water inlet holes should be consistent.

[0031] The bottom of the wetting channel 502 is provided with a plurality of material distributing plates 503, which are uniformly and spacedly distributed around the outer sidewall of the central column 12, and a gap for passing the brewing raw materials is formed between any two adjacent material distributing plates 503. One end of the material distributing plate 503 is fixedly connected with the outer sidewall of the central column 12, and the other end extends radially along the central column 12 to contact the inner sidewall of the shell 5. The connection between the material distributing plate 503 and the central column 12 is by welding or bolting, and in this embodiment, the connection is by welding. The number of the material distributing plates 503 can be 10-16, and in this embodiment, the number of the material distributing plates 503 is 10 and they are uniformly and spacedly distributed along the circumference of the central column 12. The acute angle formed between the material distributing plate 503 and the vertical direction is 17-27°, and any two adjacent material distributing plates 503 are oppositely arranged. Specifically, the bottom end of the middle material distributing plate 503 is inclined to the right, and the bottom ends of the material distributing plates 503 on both sides thereof are inclined to the left, that is, the gap between the material distributing plate 503 and the material distributing plate 503 on one side thereof has a width at the upper end smaller than that at the lower end, and the gap between the material distributing plate 503 and the material distributing plate 503 on the other side thereof has a width at the upper end larger than that at the lower end. The brewing raw materials flow down in the form of a hollow cylinder, fall onto the material distributing plate 503 by gravity, and then flow out after tumbling and guiding. The movement direction of the brewing raw materials is changed, the mixing effect of the brewing raw materials and water droplets is improved, and the wetting of the brewing raw materials is further more uniform. In this embodiment, the brewing raw materials contact the material distributing plate 503 and change the movement state during the falling process by gravity, and no additional power is required, that is, no additional stirring equipment is required, thereby saving the wetting cost.

[0032] A sterilization cylinder 6 is arranged below the shell 5 and communicates with the shell 5. The sterilization cylinder 6 has a cylindrical structure and is coaxial with the shell 5. The diameter of the sterilization cylinder 6 is equal to the diameter of the lower end of the shell 5, and the upper end of the sterilization cylinder 6 is fixedly connected with the lower end of the shell 5 by bolting. The bottom of the sterilization cylinder 6 is provided with a steam jacket 601 capable of introducing steam into the interior thereof. The number of the steam jackets 601 is three, and the three steam jackets 601 are distributed along the height direction of the sterilization cylinder 6. The steam jacket 601 has a hollow annular shell 5-like structure, and the inner diameter thereof is equal to the outer diameter of the sterilization cylinder 6. A plurality of gas outlet holes are formed in the inner sidewall of the steam jacket 601 and are uniformly and spacedly distributed along the circumference thereof. The bottom of the sterilization cylinder 6 is provided with a gas inlet hole 602 corresponding to the gas outlet holes. Steam is introduced into the steam jacket 601 by an external steam equipment, and then sequentially passes through the gas outlet holes and the gas inlet hole 602 to enter the sterilization cylinder 6. In this embodiment, the inner sidewall of the steam jacket 601 is in close connection with the outer sidewall of the sterilization cylinder 6 to avoid the steam flowing out from the gap between the inner sidewall of the steam jacket 601 and the outer sidewall of the sterilization cylinder 6.

[0033] As Figure 2As shown, the bottom of the inner wall of the sterilization cylinder 6 is provided with a plurality of uniform rods, the axis of the uniform rod is perpendicular to the axis of the sterilization cylinder 6, and there is a space between adjacent two uniform rods for the outflow of the brewing raw materials. In this embodiment, the bottom end of the central column 12 extends to the upper part of the sterilization cylinder 6 and is coaxially fixedly connected with a fixed rod. One end of the uniform rod is fixedly connected with the outer side wall of the fixed rod, and the other end extends radially along the fixed rod to contact the inner side wall of the sterilization cylinder 6. The number of uniform rods is three and they are uniformly and spacedly distributed along the circumference of the fixed rod. The falling brewing raw materials with water droplets collide with the uniform rods, change the movement direction of part of the brewing raw materials, cause the mutual contact and collision between the brewing raw materials, and make the moisture of the brewing raw materials more uniform. At the same time, the sterilization of the brewing raw materials is more thorough.

[0034] The bottom of the shell 5 is provided with a wetting bin 7 for the brewing raw materials after wetting. The top of the wetting bin 7 is provided with a water spraying pipe 701 capable of spraying water to the inner wall thereof. The water spraying pipe 701 is used for cleaning the wetting bin 7. Specifically, the top end of the wetting bin 7 is inwardly recessed to form a first inwardly recessed portion, and the water spraying pipe 701 is arranged in the first inwardly recessed portion. In this embodiment, the number of water spraying pipes 701 is three and they are uniformly and spacedly distributed along the circumference of the first inwardly recessed portion. When the device stops working, water is sprayed into the wetting bin 7 through the water spraying pipe 701 to flush and cool it. The water spraying pipe 701 is inclined downward toward the water inlet direction of the wetting bin 7 and has a radial angle of 1-5° with the wetting bin 7, so that the water flow has a tangential velocity component and can form a vortex in the wetting bin 7, thereby improving the cleaning effect. The bottom end of the wetting bin 7 is inwardly recessed to form a second inwardly recessed portion 702, and the bottom end of the second inwardly recessed portion 702 is connected with the downstream equipment.

[0035] In this embodiment, the wetting device further includes three parallel support legs 9, and the space between the adjacent support legs 9 forms a containing space for placing the shell 5, the sterilization cylinder 6 and the wetting bin 7. The wetting bin 7 is fixedly connected with the support legs 9.

[0036] The wetting device has strict requirements for the amount of material entering its interior. If the amount of material is not uniform, the wetting effect of the brewing raw materials will be affected, resulting in uneven wetting, part of the brewing raw materials having more water content and part of the brewing raw materials having less water content. Therefore, the upper part of the shell 5 is provided with a feeding device for continuously feeding the interior thereof. The feeding device includes an inlet cylinder 1, an intermediate cylinder 3 and an outlet cylinder 4 arranged from top to bottom along the height direction. The bottom end of the outlet cylinder 4 is communicated with the top end of the shell 5. The brewing raw materials enter the intermediate cylinder 3 from the inlet cylinder 1 and then flow into the shell 5 through the outlet cylinder 4 for wetting. A sandglass-shaped flow guide cylinder 2 is arranged between the inlet cylinder 1 and the intermediate cylinder 3. The top end of the flow guide cylinder 2 is fixedly connected with the bottom end of the inlet cylinder 1, and the bottom end of the flow guide cylinder 2 is fixedly connected with the top end of the intermediate cylinder 3. The diameters of the two ends of the flow guide cylinder 2 are the same, and the diameter of the top end of the flow guide cylinder 2 is equal to the diameter of the bottom end of the inlet cylinder 1, and the diameter of the bottom end of the flow guide cylinder 2 is equal to the diameter of the intermediate cylinder 3.

[0037] The bottom end of the feeding cylinder 1 is provided with a first baffle plate 103 capable of adjusting the feeding amount, and the middle part of the middle cylinder 3 is provided with a first weighing sensor 302 for detecting the instantaneous flow of brewing raw materials in the middle cylinder 3. Specifically, the feeding cylinder 1 is coaxially provided with an inner cylinder 102 with open ends. The inner cylinder 102 is a cylindrical structure, and the brewing raw materials enter through the upper end opening and flow out through the lower end opening. The first baffle plate 103 is located at the bottom opening of the inner cylinder 102 and is rotationally connected with the inner side wall of the feeding cylinder 1. The first baffle plate 103 can adjust the bottom end opening of the inner cylinder 102 during rotation. In this embodiment, the first baffle plate 103 is an arc-shaped plate, the bottom end face of the inner cylinder 102 is an arc-shaped end face convex downward, and the curvature radius of the arc-shaped plate and the arc-shaped end face is the same. The concave surface of the arc-shaped plate can be closely attached to the arc-shaped end face. The outer part of the feeding cylinder 1 is provided with a feeding servo motor 101 for driving the rotation of the first baffle plate 103. The feeding servo motor 101 is connected with a controller 10, i.e. the housing of the feeding servo motor 101 is fixedly connected with the outer side wall of the feeding cylinder 1. The rotating shaft of the feeding servo motor 101 extends into the feeding cylinder 1. A plurality of rotating rods 104 are fixedly connected to the first baffle plate 103. The rotating rod 104 close to the feeding servo motor 101 is fixedly connected with the rotating shaft, and the rotating rod 104 away from the feeding servo motor 101 is rotationally connected with the inner side wall of the feeding cylinder 1. The rotation of the feeding servo motor 101 drives the rotation of the first baffle plate 103. The first baffle plate 103 can adjust the bottom end opening of the inner cylinder 102 during rotation, thereby adjusting the feeding amount of the feeding cylinder 1.

[0038] The bottom end of the intermediate cylinder 3 is provided with a second baffle plate 304 capable of adjusting the discharge amount, the discharge cylinder 4 is provided with a second weighing sensor 402 for detecting the instantaneous flow of the discharge, the middle part of the intermediate cylinder 3 is fixedly connected with a guide plate around the inner wall, the second baffle plate 304 is located at the bottom end opening of the guide plate and is rotatably connected with the inner side wall of the intermediate cylinder 3, and the second baffle plate 304 can adjust the bottom end opening of the guide plate during rotation. The top end of the guide plate is connected with the inner wall of the intermediate cylinder 3, and the guide plate and the inner side wall of the intermediate cylinder 3 are connected by welding; the bottom end of the guide plate is inwardly recessed to the center of the intermediate cylinder 3, that is, the guide plate is funnel-shaped. The second baffle plate 304 is an arc-shaped plate, the bottom end of the guide plate is an arc-shaped end face convex downward, and the curvature radius of the arc-shaped plate is equal to the curvature radius of the arc-shaped end face, and the concave surface of the second baffle plate 304 can be closely fitted with the arc-shaped end face of the guide plate. The outside of the intermediate cylinder 3 is provided with a discharge servo motor 301 for driving the rotation of the second baffle plate 304, the housing 5 of the discharge servo motor 301 is fixedly connected with the outer side wall of the intermediate cylinder 3, and the connection mode of the two is bolted connection, and the discharge servo motor 301 is connected with the controller 10. The second baffle plate 304 is fixedly connected with a driving rod on both sides of the guide cylinder, the driving rod close to the discharge servo motor 301 is fixedly connected with the rotating shaft, and the driving rod away from the discharge servo motor 301 is rotatably connected with the inner side wall of the intermediate cylinder 3, the rotating shaft of the discharge servo motor 301 drives the rotation of the second baffle plate 304 during rotation, and the second baffle plate 304 can adjust the bottom end opening of the guide cylinder during rotation, thereby adjusting the discharge amount.

[0039] The first weighing sensor 302 is used for monitoring the instantaneous feeding flow of the intermediate cylinder 3, and the second weighing sensor 402 is used for monitoring the instantaneous discharging flow in the discharging cylinder 4. The instantaneous feeding flow and the instantaneous discharging flow are transmitted to the controller 10, and the controller 10 compares the two sets of data. If the difference between the instantaneous feeding flow and the instantaneous discharging flow exceeds the preset range, the controller 10 adjusts the positions of the first baffle plate 103 and the second baffle plate 304 according to the two sets of data, so as to realize the uniform and continuous feeding into the shell 5. Specifically, the position of the first baffle plate 103 is determined according to the required feeding amount of the wetting device, so as to meet the required feeding amount of the wetting device. When the instantaneous discharging flow is lower than the instantaneous feeding flow, that is, the brewing raw materials entering the shell 5 are reduced, and the water supply amount is unchanged, the moisture content of the brewing raw materials is increased. Therefore, the controller 10 controls the discharging servo motor 301 to work, so as to drive the second baffle plate 304 to rotate and increase the opening at the bottom end of the guide plate, and then the instantaneous discharging flow meets the required amount of the wetting device. When the instantaneous discharging flow is higher than the instantaneous feeding flow, that is, the brewing raw materials entering the shell 5 are increased, and the water supply amount is unchanged, the moisture content of the brewing raw materials is reduced. Therefore, the controller 10 controls the servo motor to work, so as to drive the second baffle plate 304 to rotate and reduce the opening at the bottom end of the guide plate, and then the instantaneous discharging flow meets the required amount of the wetting device. That is, the feeding device can uniformly and continuously feed into the shell 5, so that the water supply amount and the amount of brewing raw materials are always in a balanced state, and then the wetting of the brewing raw materials is more uniform. At the same time, the first weighing sensor 302 and the second weighing sensor 402 cooperate to realize the balanced feeding of the feeding device, so as to avoid the accumulation of brewing raw materials in the feeding device or the lack of materials.
