Description

Technical Field

[0001] This application relates to the technical field of fruit wine production equipment, specifically an automatic mixing device for multi-component fruit wine base wine. Background Technology

[0002] In the fruit wine production industry, the flavor harmony, alcohol uniformity, and color stability of the base wine are key indicators that determine product quality. Therefore, it is often necessary to blend different types of base wine in specific proportions.

[0003] In existing technologies, the base liquor mixing process mainly relies on single-shaft stirring devices or static mixers. Single-shaft stirring generates fluid disturbance through the rotation of a single stirring paddle, using shear force and convection to promote liquid mixing; while static mixers use the guiding effect of internal fixed elements to continuously divide and recombine the fluid during the flow process to achieve mixing.

[0004] However, the aforementioned traditional technologies have limitations in the flow field distribution of single-axis mixing in practical applications. For base wines with large viscosity differences or obvious density stratification, local clusters of fluid are easily formed, causing high-concentration base wines to deposit at the bottom or top of the container, making it difficult to achieve uniform dispersion. Although static mixers have no moving parts, they are limited by the fixed flow channel structure, resulting in low mixing efficiency for high-viscosity fluids or base wines containing particulate components, and the mixing effect fluctuates significantly with the flow rate.

[0005] Therefore, this application provides an automatic mixing device for multi-component fruit wine base wine to solve the above problems. Utility Model Content

[0006] This application provides an automatic mixing device for multi-component fruit wine base liquor, which aims to solve the problems mentioned in the background art, such as insufficient uniformity of base liquor mixing and low mixing efficiency caused by overlapping flow fields of traditional stirring devices.

[0007] To achieve the above object, the present application provides the following technical solution: A multi-component fruit wine base wine automatic mixing device, including a mixing tank, a plurality of independent base wine storage tanks provided on the mixing tank, and a three-layer variable pitch stirring mechanism provided on the mixing tank. A controller is provided on the mixing tank; the three-layer variable pitch stirring mechanism includes a top-layer large-diameter propeller, a middle-layer inclined blade paddle, and a bottom-layer small-diameter propeller. A first rotating shaft connected to the large-diameter propeller is rotatably provided at the central position inside the mixing tank. The inside of the mixing tank is symmetrically arranged radially with a second rotating shaft and a third rotating shaft respectively connected to the inclined blade paddle and the small-diameter propeller. Servo motors fixedly connected to the ends of the first rotating shaft, the second rotating shaft, and the third rotating shaft are provided at the top of the mixing tank. The servo motors are electrically connected to the controller. Through the differential design of the stirring components and speed control, a composite flow field covering the upper, middle, and lower layers of the mixing tank is constructed, effectively solving the problems of uneven mixing and liquid cluster deposition in traditional single-axis stirring, improving the mixing efficiency of the base wine, and taking into account the dispersion effects of base wines with different densities and viscosities. In particular, it has the advantage of low-damage mixing for base wines containing pulp precipitation or heat-sensitive components.

[0008] Preferably, to avoid overlapping interference of the stirring areas: the first rotating shaft, the second rotating shaft, and the third rotating shaft are arranged in a "pin" shape. By arranging the three rotating shafts in a "pin" shape spatial layout with a vertex angle of °, the stirring areas of the top layer, middle layer, and bottom layer are misaligned in the horizontal plane, avoiding the energy loss and mixing blind spots caused by the superposition of the flow fields during traditional coaxial multi-paddle stirring, improving the utilization rate of the stirring area, and ensuring that there is no stirring dead angle in the tank.

[0009] Preferably, the mixing tank is a conical bottom cylindrical structure. The combined design of the conical bottom angle and the cylindrical tank body reduces the liquid flow resistance at the bottom of the mixing tank. Combined with the axial flow of the bottom-layer small-diameter propeller, it completely solves the problem of liquid deposition in traditional flat-bottom tanks and reduces the base wine residue rate of traditional devices.

[0010] Preferably, the output end of the storage tank is connected to the mixing tank through a feed pipeline. An electromagnetic metering pump and a mass flow sensor are sequentially arranged on the feed pipeline along the liquid flow direction. The electromagnetic metering pump and the mass flow sensor are both electrically connected to the controller. Through the closed-loop control dynamic metering system, the precise control of the base wine feed ratio error is achieved, improving the accuracy compared with traditional manual adjustment or volumetric metering methods, and meeting the stringent requirements of high-end fruit wines for the ratio of flavor substances.

[0011] Preferably, to facilitate the discharge of the mixed fruit wine from the mixing tank: the output end of the mixing tank is fixedly connected to a discharge pipe, and a control valve electrically connected to the controller is installed on the discharge pipe. The conical bottom structure combined with the low-position discharge design allows the mixed fruit wine to be discharged by gravity, and with the precise opening and closing of the electrically controlled valve, the discharge process is achieved without residue or leakage.

[0012] Preferably, to facilitate support of the mixing tank: three support legs are fixedly connected to the bottom of the mixing tank in a circular array, and shock-absorbing pads are fixedly connected to the bottom of the support legs. The bottom of the shock-absorbing pads is provided with anti-slip texture. The three-support-leg structure of the circular array provides stable mechanical support, and together with the dual shock-absorbing design of the shock-absorbing pads, it reduces the vibration amplitude and noise during device operation.

[0013] This application constructs a composite flow field covering the upper, middle and lower layers of the mixing tank through differentiated stirring component design and speed control. This effectively solves the problems of uneven mixing and liquid agglomeration in traditional single-shaft stirring, improves the mixing efficiency of base wine, and takes into account the dispersion effect of base wines with different densities and viscosities. It has a low-damage mixing advantage, especially for base wines containing fruit pulp sediment or heat-sensitive components.

[0014] This application achieves precise control of the base wine feeding ratio error through a closed-loop controlled dynamic metering system, improving the accuracy compared to traditional manual adjustment or volumetric metering methods, and meeting the stringent requirements of high-end fruit wines for the ratio of flavor substances.

[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0020] Embodiment 1

[0021] This embodiment provides an automatic mixing device for multi-component fruit wine base wine. As Figure 1-2 shown, the mixing device includes a mixing tank 1, a plurality of independent base wine storage tanks 2 provided on the mixing tank 1, and a three-layer variable pitch stirring mechanism 3 provided on the mixing tank 1. A controller 4 is provided on the mixing tank 1; the three-layer variable pitch stirring mechanism 3 includes a top-layer large-diameter propeller 31, a middle-layer inclined blade paddle 32, and a bottom-layer small-diameter propeller 33. A first rotating shaft 34 connected to the large-diameter propeller 31 is rotatably provided at the central position inside the mixing tank 1. Second rotating shafts 35 and third rotating shafts 36 respectively connected to the inclined blade paddle 32 and the small-diameter propeller 33 are symmetrically arranged along the radial direction inside the mixing tank 1. Servo motors 37 fixedly connected to the ends of the first rotating shaft 34, the second rotating shaft 35, and the third rotating shaft 36 are provided on the top of the mixing tank 1. The servo motors 37 are electrically connected to the controller 4. Through the differential design of the stirring components and speed control, a composite flow field covering the upper, middle, and lower layers of the mixing tank 1 is constructed, effectively solving the problems of uneven mixing and liquid cluster deposition in traditional single-axis stirring, improving the base wine mixing efficiency, and at the same time taking into account the dispersion effects of base wines with different densities and viscosities. Especially, it has the advantage of low-damage mixing for base wines containing pulp precipitation or heat-sensitive components. When the top-layer large-diameter propeller 31 rotates at a low speed, a large-range vortex flow field is formed on the liquid surface, driving the upper-layer base wine to move in the circumferential and axial directions, breaking the liquid surface stratification; the middle-layer inclined blade paddle 32 rotates at a medium speed, using the 45° inclined blades to generate radial shear force, cutting the middle-layer fluid into small liquid clusters and promoting radial mixing; the bottom-layer small-diameter propeller 33 rotates at a high speed, lifting the high-concentration base wine deposited at the bottom upward through strong axial flow, and forming a turbulent flow in cooperation with the conical bottom structure. The three are independently speed-regulated by the servo motors 37 (the speed ratio is about 1:2:3), constructing a gradient flow field of "upper vortex - middle shear - lower dispersion" in the vertical direction, and improving the mixing efficiency.

[0022] In order to avoid overlapping interference in the stirring area: the first rotating shaft 34, the second rotating shaft 35, and the third rotating shaft 36 are arranged in a "pin" shape. By arranging the three rotating shafts in a "pin" shape space layout with a vertex angle of 120°, the stirring areas of the top layer, the middle layer, and the bottom layer are misaligned in the horizontal plane, avoiding the energy loss and mixing blind spots caused by the superposition of the flow fields during traditional coaxial multi-paddle stirring, improving the utilization rate of the stirring area, and ensuring that there is no stirring dead angle in the tank.

[0023] The mixing tank 1 has a conical bottom cylindrical structure. The combination of the conical bottom angle (preferably 60°-90°) and the cylindrical tank body reduces the liquid flow resistance at the bottom of the mixing tank 1. Combined with the axial flow of the small-diameter propeller 33 at the bottom, this completely solves the liquid sedimentation problem of traditional flat-bottomed tanks and reduces the residual base liquor rate of traditional devices. The cylindrical tank body provides a stable circumferential flow field space in the middle. The conical bottom structure gradually reduces the cross-sectional area of ​​the tank bottom from πR² at the top to the discharge port area, forming a "fluid convergence effect." When the small-diameter propeller 33 at the bottom rotates at high speed, the fluid in the conical bottom region flows towards the central discharge port under the action of axial thrust. At the same time, the conical surface reflection effect continuously replenishes the liquid at the edge to the center, forming a spiraling upward flow field at the bottom. This design allows the denser base liquor to slide along the conical wall towards the center under the action of gravity and the flow field and be instantly dispersed by the bottom propeller blades, avoiding the concentration stratification caused by dead corners in flat-bottomed tanks.

[0024] To facilitate the discharge of the mixed fruit wine from the mixing tank 1, a discharge pipe 11 is fixedly connected to the output end of the mixing tank 1. A control valve 12, electrically connected to the controller 4, is installed on the discharge pipe 11. The conical bottom structure combined with the low-position discharge design allows the mixed fruit wine to be discharged by gravity. Combined with the precise opening and closing of the electrically controlled valve 12, the discharge process is residue-free and leak-free. The discharge pipe 11 is connected to the lowest point of the conical bottom of the mixing tank 1, ensuring a stable fluid flow rate. The control valve 12 is a pneumatic butterfly valve or an electric ball valve. After mixing is complete, the controller 4 sends a command to open the valve, and the uniformly mixed liquid accumulated at the bottom of the cone is discharged along the discharge pipe 11 under gravity.

[0025] To facilitate support of the mixing tank 1, three support legs 5 are fixedly connected to the bottom of the mixing tank 1 in a circular array. A shock-absorbing pad 51 is fixedly connected to the bottom of each support leg 5, and the bottom of the shock-absorbing pad 51 has anti-slip textures. The three-support-leg structure in the circular array provides stable mechanical support, and combined with the dual shock-absorbing design of the shock-absorbing pad 51, reduces the vibration amplitude and noise during operation. The three support legs 5 are evenly distributed at a 120° angle at the bottom of the mixing tank 1, forming an equilateral triangular support surface. The load-bearing capacity of a single support leg 5 is 1.5 times the full load weight of the tank, ensuring self-stability when the center of gravity shifts. The shock-absorbing pad 51 adopts a composite structure with a hard upper layer and a soft lower layer. The upper layer absorbs high-frequency vibrations, and the lower layer absorbs low-frequency vibrations. The anti-slip textures increase the coefficient of friction with the ground, effectively blocking the transmission of vibration from the stirring motor to the ground, while also preventing displacement and slippage during operation.

[0026] Example 2

[0027] Unlike Example 1, the output end of the storage tank 2 is connected to the mixing tank 1 via the feed pipe 21. An electromagnetic metering pump 211 and a mass flow sensor 212 are sequentially installed along the liquid flow direction on the feed pipe 21. Both the electromagnetic metering pump 211 and the mass flow sensor 212 are electrically connected to the controller 4. Through a closed-loop controlled dynamic metering system, precise control of the base wine feeding ratio error is achieved, improving accuracy compared to traditional manual adjustment or volumetric metering methods, and meeting the stringent requirements of high-end fruit wines for flavor compound ratios. The mass flow sensor 212 monitors the mass flow rate of the base wine in the pipe in real time and transmits the data to the controller 4. The controller 4 calculates the target flow rate of each storage tank 2 according to a preset formula (e.g., base wine A:B:C=3:2:1) and dynamically adjusts the speed of the electromagnetic metering pump 211 using a PID algorithm. When multiple feed pipes 21 operate independently, the controller 4 synchronously coordinates the flow rates of each pipe using a time-slicing algorithm, ensuring that multiple base wines are injected into the mixing tank 1 in the correct proportions.

[0028] The wiring diagram of the servo motor 37 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to the actual use. Therefore, the control method and wiring layout of the servo motor 37 will not be explained in detail.

[0029] The control method of this application is controlled by controller 4. The control circuit of controller 4 can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0030] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
