Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of mixing devices, and particularly relates to a raw material mixing device for a composite beverage and a production process of the composite beverage. BACKGROUND

[0002] In the field of beverage production, especially the preparation of composite beverages, uniform mixing of various liquid, slurry or particle-containing raw materials is often involved. The mixing effect is directly related to the taste, stability and quality uniformity of the final product. Traditional mixing devices often use mechanical stirring methods, such as rotating stirring paddles or stirring blades in the stirring tank, which preliminarily mix the materials through the shearing and convection effects of the paddles. However, for composite beverage raw materials with high viscosity, large differences in ingredient density or the need for gas-liquid mixing, single mechanical stirring often has problems such as insufficient mixing force, long mixing time, and easy formation of mixing dead angles, which may cause the product to separate, precipitate or have uneven taste.

[0003] To further improve the mixing efficiency and uniformity, some improved schemes have appeared in the prior art. For example, a "fruit pulp beverage raw material mixing and stirring device" is disclosed in Chinese Patent No. CN221964975U. The device mainly includes a tank body, a mixing bin arranged in the tank body, and a sieve pipe at the bottom of the mixing bin. Its working principle is: after the fruit pulp raw materials are broken and mixed by the stirring assembly in the mixing bin, the fruit pulp juice mixture is filtered and discharged through the sieve screen in the bottom sieve pipe, while the larger fruit pits are intercepted on the surface of the sieve screen. Then, the entire mixing bin is lifted upward by the lifting assembly, so that the bottom of the mixing bin is separated from the sieve screen, and the intercepted fruit pits can slide down along the inclined surface of the sieve screen, and finally be discharged through the discharge assembly on the side wall of the tank body. The main technical contribution of this device is to realize the online separation and centralized cleaning of fruit pits and fruit pulp mixture during the production of fruit pulp beverages, optimize the subsequent process, and help improve the taste of the beverage.

[0004] However, the above-mentioned prior art still has certain limitations. Its technical core focuses on the solid-liquid separation (fruit pit separation) function after mixing, rather than the intensification of the mixing process itself. For the mixing link, it still relies on the traditional top stirring assembly and does not introduce other auxiliary means that can significantly improve the mixing dynamics efficiency. SUMMARY

[0005] The present application aims to at least solve one of the technical problems of poor stirring and mixing effect in the prior art. To this end, the present application proposes a raw material mixing device for a composite beverage and a production process of the composite beverage.

[0006] To achieve the above objectives, the specific technical solution of the present invention is as follows: a raw material mixing device for compound beverages includes a mixing tank, a rotating tube that can rotate inside the mixing tank, a fixing rod that is horizontally fixed on the bottom surface of the rotating tube, and an air jet block that is fixed above the fixing rod. An air passage is opened upward in the lower part of the inner cavity of the rotating tube, and an air jet hole is penetrated into the air passage on the upper surface of the air jet block.

[0007] Preferably, a one-way valve is fixed to the inner ring wall of the ventilation channel, and an air inlet is provided on the upper part of the outer circumferential surface of the rotating tube, wherein the air inlet communicates with the interior of the ventilation channel, and a collar is also fitted on the outer circumferential surface of the air inlet, and a connecting pipe is also fixed on the outer circumferential surface of the collar.

[0008] Preferably, a motor base is fixed to the upper surface of the mixing tank, and a second motor is also fixed to the upper surface of the motor base. A rotating tube extends from the output end of the second motor into the interior of the mixing tank, and a mixing blade is fixed to the outer circumference of the rotating tube.

[0009] Preferably, a crown gear is fixed at the center of the bottom surface of the mixing tank, and a fixing block is fixed downward at the center of the bottom surface of the fixing rod. Connecting shafts are fixed on both sides of the outer surface of the fixing block, and a rotatable stirring shaft is sleeved on the outer circumference of the connecting shaft.

[0010] Preferably, stirring rods are evenly distributed and fixed on the outer circumferential surface of the stirring shaft, and the stirring shaft and the fixed rods are fixed in a cross-shaped distribution. A gear is also fixed on the outer circumferential surface of the stirring shaft, wherein the gear meshes with a crown gear.

[0011] Preferably, a dual-head motor is fixed inside the fixing block, and rotating rods are provided at the output ends on both sides of the dual-head motor, with one end of the rotating rods extending into the interior of the stirring shaft.

[0012] Preferably, the stirring shaft has a hollow internal structure, and a second circulation hole extends from the top of the stirring rod into the stirring shaft. A first circulation hole is formed on the outer periphery of the stirring shaft, and an exhaust pipe is fixed on one side of the top of the mixing tank.

[0013] Preferably, the mixing tank is placed on one side of the center bottom surface of the frame, and a first raw material tank and a second raw material tank are respectively fixed on the upper two sides of the frame, wherein the interior of the first raw material tank and the second raw material tank are hollow.

[0014] Preferably, a first discharge pipe is fixed to the bottom output end opening of the first raw material barrel, and a conveying pipe is fixed between the end of the first discharge pipe and the top. A first motor for conveying raw materials is also fixed to one end of the conveying pipe.

[0015] The raw material mixing device for compound beverages of the present invention has the following advantages: 1. The raw material mixing device and production process of the compound beverage: When the mixing process begins, a second motor drives the rotating tube and mixing blades to rotate for main stirring. Simultaneously, an external air pump starts, and clean compressed air enters the ventilation channel through the connecting pipe, collar, and air inlet. After overcoming the resistance of the one-way valve, it enters the air jet block cavity and is finally sprayed into the mixture in the form of bubbles from the air jet hole. These rising bubble groups further disturb the liquid flow field, increasing the turbulence of the liquid and the gas-liquid contact area. This is particularly beneficial for beverage mixing processes that require aeration or deodorization, significantly improving the uniformity and efficiency of mixing. Attached Figure Description

DETAILED DESCRIPTION

[0019] The application will be described in detail below in combination with the drawings and specific examples.

[0020] As Figures 1-3 shown, the raw material mixing device of the composite beverage of the application is based on a solid and stable frame 1, which is welded by high-strength metal materials, not only provides a reliable support foundation for the whole device, but also ensures that it will not be deformed or deviated due to vibration or load during continuous work. On the upper left and right sides of the frame 1, a first raw material barrel 11 and a second raw material barrel 12 are respectively fixedly installed, both of which are made of food-grade stainless steel material, hollow inside, and the volume can be customized according to actual production needs, and are respectively used for storing different types or proportions of beverage raw materials, such as juice concentrate, syrup, vitamin additives, etc. The top of the raw material barrel is usually provided with an openable sealing cover for easy feeding and cleaning, and the side is provided with a transparent liquid level observation window to facilitate the operator to master the remaining amount of raw materials in real time.

[0021] The bottom outlet of the first raw material barrel 11 is connected with a vertical downward first discharging pipe 111, which is fixed tightly with the bottom of the raw material barrel through flange, ensuring no leakage. The lower end of the first discharging pipe 111 is connected with a horizontal conveying pipe 131, which is made of corrosion-resistant food-grade hose or hard pipe, and one end of which is provided with a conveying pump driven by the first motor 13. When it is needed to put the raw material in the first raw material barrel 11 into the mixing barrel 2, the first motor 13 is started, and the conveying pump is operated to generate suction force, so that the raw material is sucked into the conveying pipe 131 through the first discharging pipe 111 and is smoothly conveyed along the pipe into the mixing barrel 2. Similarly, the bottom outlet of the second raw material barrel 12 is directly connected with the mixing barrel 2 through a second discharging pipe 121, which can be provided with a flow control valve to adjust the input rate of the raw material. Among them, the first raw material barrel 11 and the second raw material barrel 12 are erected at a higher position than the mixing barrel 2. This high differential layout ingeniously utilizes the gravitational potential energy to assist the natural flow of the raw material in the pipe, reduces the load of the conveying pump, and also makes the raw material feeding process more smooth and energy-saving.

[0022] As shown in Figures 4-9 The mixing barrel 2 is the core mixing container of the whole device, and its main body is in cylindrical structure. The barrel wall is designed in double-layer stainless steel, and the middle part can be filled with thermal insulation material to adapt to the mixing process with special temperature requirements. The upper end surface of the mixing barrel 2 is fixed with a motor seat 22 at the central position, which is firmly connected with the upper edge of the mixing barrel through bolts, and the upper part of which is provided with a second motor 221 installed on the plane. The second motor 221 is preferably a speed-adjustable reduction motor, and its output shaft extends vertically downward and is connected to a rotating pipe 222 extending into the inside of the mixing barrel 2 after penetrating through the motor seat 22. The rotating pipe 222 is in hollow shaft structure, and a plurality of groups of mixing blades 223 are uniformly welded on the outer surface thereof. The inclination angles of the mixing blades 223 are optimized through fluid mechanics, which can generate disturbance to the liquid in the barrel when rotating, so as to promote the mutual dissolution and dispersion between different raw materials.

[0023] At the bottom end of the rotating tube 222, a solid fixed rod 23 is fixed transversely, the two ends of which keep proper gaps with the inner wall of the mixing bucket 2 to avoid collision during rotation. The end part of the mixing blade 223 is fixed and connected with the upper surface of the fixed rod 23 through a support rib plate, which significantly improves the rigidity and stability of the whole stirring structure. Above the fixed rod 23, a long strip-shaped air jet block 231 is also fixed and installed, the inside of which is provided with a cavity, and the top upper surface thereof is provided with air jet holes 232 along the length direction. The air jet block 231 rotates synchronously with the rotating tube 222. At the lower part of the inner cavity of the rotating tube 222, an elongated air passage 224 is upwardly provided, which is in communication with the air jet holes 232. The inner annular wall of the air passage 224 is provided with a one-way valve 225, which only allows gas to flow from the inside of the rotating tube 222 to the air jet block 231, and effectively prevents the liquid in the mixing bucket 2 from flowing back into the air passage 224 due to pressure or siphon effect, thereby avoiding the risk of blockage and pollution.

[0024] At the upper part of the outer circumferential surface of the rotating tube 222, an annular air inlet hole 226 is provided, which is in communication with the air passage 224 inside the rotating tube. The air inlet hole 226 is externally provided with a relatively rotatable sealing sleeve ring 5, which is rotatably and sealingly connected with the rotating tube 222 through a bearing. The outer side of the sleeve ring 5 is fixedly connected with a connecting pipe 51, which can be externally connected with a high-pressure air pump or a factory compressed air pipe. When the mixing process starts, the second motor 221 drives the rotating tube 222 and the mixing blade 223 to rotate for main body stirring, and at the same time, the external air pump is started. Clean compressed air enters the air passage 224 through the connecting pipe 51, the sleeve ring 5 and the air inlet hole 226, enters the cavity of the air jet block 231 after overcoming the resistance of the one-way valve 225, and finally is sprayed into the mixing liquid in the form of bubbles from the air jet holes 232. These rising bubble groups further disturb the liquid flow field, increase the degree of turbulence of the liquid and the gas-liquid contact area, which is particularly advantageous for beverage mixing processes that need to be aerated or remove odor, and significantly improves the uniformity and efficiency of mixing.

[0025] As Figures 6-10As shown, in the center of the bottom surface of the mixing barrel 2, a crown gear 24 with an inner ring structure is fixed by welding or bolting. The tooth surface of the crown gear 24 faces upwards and is coaxial with the mixing barrel 2. In the center of the bottom surface of the fixed rod 23, a cylindrical fixed block 26 is fixed vertically downwards. The two sides of the fixed block 26 are symmetrically fixed with two horizontally outward extending connecting shafts 25. Each connecting shaft 25 is provided with a stirring shaft 3 that can rotate around it through a bearing sleeve. The two stirring shafts 3 and the upper fixed rod 23 are distributed in a cross shape in space, forming a three-dimensional stirring network in the lower part of the mixing barrel. On the outer circumferential surface of each stirring shaft 3, a plurality of stirring rods 31 are welded at equal intervals along the axial direction, which can be designed as straight rods, inclined rods or blades to generate a complex local flow field. On the outer circumferential surface of each stirring shaft 3, a small diameter gear 32 is also fixed and installed, which is in meshing state with the fixed crown gear 24 at the bottom.

[0026] When the second motor 221 drives the rotating tube 222 and the fixed rod 23 to rotate, the fixed block 26 and the two connecting shafts 25 connected thereto will revolve, thereby driving the two stirring shafts 3 to perform planetary revolution around the central axis of the mixing barrel. In this process, since the gear 32 on the stirring shaft 3 is in meshing with the stationary crown gear 24, the transmission of the gear pair will force the stirring shaft 3 to simultaneously rotate around its own connecting shaft 25 axis. This compound motion of revolution and rotation makes the motion trajectory of the stirring shaft 3 and the stirring rod 31 extremely complex, which can strongly and fully stir the bottom of the mixing barrel 2, especially the areas near the barrel wall and the center, effectively eliminating the dead zones that may exist in conventional stirring, ensuring the uniformity of the materials in the entire mixing barrel, especially suitable for high viscosity or solid-liquid mixed beverage raw materials.

[0027] As shown, Figure 10 In order to further enhance the mixing effect, a double-head motor 4 is integrated and installed in the internal cavity of the fixed block 26. The two end output shafts of the double-head motor 4 are respectively connected with a rotating rod 41, each of which extends outward and is inserted into the internal cavity of the corresponding side stirring shaft 3. The stirring shaft 3 is designed as a hollow tubular structure, and the cavity inside it leaves a flow passage with the rotating rod 41. A plurality of first circulation holes 33 are formed in the pipe wall of the stirring shaft 3, which lead to the main liquid in the mixing barrel 2. At the same time, a second circulation hole 311 is also formed in the top end of each stirring rod 31, which is in communication with the inside.

[0028] When the stirring shaft 3 is driven by the crown gear 24 to revolve and rotate, the double-head motor 4 inside the fixed block 26 can be started at the same time. The double-head motor 4 drives the rotating rods 41 at both ends to rotate at high speed, and the impeller 42 installed at the end of the rotating rod 41 rotates in the cavity of the stirring shaft 3. The impeller 42, as the impeller of a micro centrifugal pump, generates strong suction effect, forcing the liquid in the mixing bucket to be sucked into the cavity from the first circulation hole 33 on the outer wall of the stirring shaft 3, and then the liquid flows along the cavity under the action of centrifugal force and is sprayed out at high speed from the second circulation hole 311 at the top end of the stirring rod 31. This internal circulation process forms a strong jet flow and a negative pressure area in the local area of the mixing bucket 2, not only strengthening the shear and mixing at the micro level, but also re-raising the possible precipitated solid particles at the bottom and participating in the circulation, thereby realizing high-efficiency and homogeneous mixing in a short time, greatly shortening the entire production cycle of the beverage and improving the stability of product quality. The whole device works cooperatively through the above-mentioned multi-layer and multi-mode mixing mechanism, forming a high-efficiency, reliable and widely adaptable composite beverage raw material mixing system.

[0029] The production process of the composite beverage is as follows: S1. Different liquid or slurry raw materials are respectively added to the first raw material bucket 11 and the second raw material bucket 12; the first motor 13 is started to pump the raw materials in the first raw material bucket 11 into the mixing bucket 2 through the conveying pipe 131; at the same time, the control valve on the second discharge pipe 121 is opened, so that the raw materials in the second raw material bucket 12 flow into the mixing bucket 2 through the second discharge pipe 121 under the action of gravity; the supply flow and proportion of the raw materials are adjusted by controlling the rotating speed of the first motor 13 and the opening degree of the valve of the second discharge pipe 121; S2. The second motor 221 is started to drive the rotating pipe 222 and the mixing blade 223 fixed thereon to rotate at a set speed, and the multiple raw materials entering the mixing bucket 2 are preliminarily sheared and convectively mixed; at the same time, the air pump connected with the connecting pipe 51 is started to continuously pump gas into the air inlet hole 226 of the rotating pipe 222, and the gas is uniformly sprayed out from the air injection hole 232 of the air injection block 231 rotating with the rotating pipe 222 after passing through the air passage 224 and the one-way valve 225, forming a bubble flow, which further disturbs the liquid by using the rising motion and breaking effect of the gas, and enhances the macro mixing and mass transfer process; S3. Under the driving of the rotating pipe 222, the fixed rod 23 and the fixed block 26 and the connecting shaft 25 at the bottom thereof revolve around the central axis of the mixing bucket 2, thereby driving the two stirring shafts 3 to revolve; the gears 32 on the stirring shafts 3 mesh with the crown gear 24 fixed to the bottom of the mixing bucket 2, forcing the stirring shafts 3 to revolve while rotating around the respective connecting shafts 25; the stirring rods 31 fixed to the stirring shafts 3 are thereby subjected to compound planetary motion, and the materials in the lower layer of the mixing bucket 2, especially the bottom and side wall regions, are subjected to strong scraping and stirring, eliminating the mixing dead zone and ensuring uniform dispersion of the materials in the whole bucket domain; S4. Start the double-head motor 4 built in the fixed block 26 to drive the rotating shaft 41 at both ends and the impeller 42 at the end to rotate at high speed; the impeller 42 generates negative pressure in the hollow cavity of the stirring shaft 3 to suck the liquid in the mixing barrel 2 into the cavity through the first circulating hole 33 on the wall of the stirring shaft 3, and then injects the liquid back into the barrel at high speed through the second circulating hole 311 at the top end of the stirring rod 31 after pressurization; this process forms a local high shear zone and a directional jet in the mixing system, which can strongly break up liquid droplets or particle groups, significantly improving the micro-mixing uniformity and dispersion stability; S5. Real-time monitoring of the mixing uniformity, temperature or viscosity parameters of the material in the mixing barrel 2; according to the process requirements, the rotating speed of the second motor 221, the flow of the air pump, the rotating speed of the double-head motor 4 and the duration of each step are controlled; when the material reaches the preset mixing endpoint indicators, the double-head motor 4, the air pump and the second motor 221 are stopped in turn, the discharge valve at the bottom of the mixing barrel 2 is opened, and the mixed composite beverage product is discharged for subsequent filling or processing.

[0030] The raw material mixing device of the composite beverage and the production process of the composite beverage work as follows: when the mixing process starts, the second motor 221 drives the rotating pipe 222 and the mixing blade 223 to rotate for main stirring, and at the same time, the external air pump is started, clean compressed air enters the air passage 224 through the connecting pipe 51, the sleeve 5 and the air inlet hole 226, overcomes the resistance of the one-way valve 225 and enters the cavity of the air jet block 231, and finally is sprayed into the mixing liquid in the form of bubbles from the air jet hole 232. These rising bubble groups further disturb the liquid flow field, increase the degree of turbulence of the liquid and the gas-liquid contact area, which is particularly beneficial for beverage mixing processes that require aeration or odor removal, significantly improving the uniformity and efficiency of mixing; When the second motor 221 drives the rotating pipe 222 and the fixed rod 23 to rotate, the fixed block 26 and the two connecting shafts 25 connected thereto revolve, thereby driving the two stirring shafts 3 to perform planetary revolution around the central axis of the mixing barrel. In this process, since the gears 32 on the stirring shafts 3 are engaged with the stationary crown gear 24, the transmission of the gear pair will force the stirring shafts 3 to simultaneously revolve around the axis of the connecting shaft 25. This combined motion of revolution and rotation makes the motion trajectory of the stirring shafts 3 and the stirring rods 31 extremely complex, which can strongly and fully stir the bottom of the mixing barrel 2, especially the areas near the barrel wall and the center, effectively eliminating the dead zones that may exist in conventional stirring, ensuring the uniformity of the material in the entire mixing barrel, and being particularly suitable for high-viscosity or solid-liquid mixing of beverage raw materials; When the stirring shaft 3 is driven to revolve and rotate by the crown gear 24, the double-head motor 4 inside the fixed block 26 can be started at the same time. The double-head motor 4 drives the rotating rods 41 at both ends to rotate at high speed, and the impellers 42 installed at the ends of the rotating rods 41 rotate in the cavity of the stirring shaft 3. The impellers 42, as the impellers of the micro centrifugal pump, generate strong suction effect, forcing the liquid in the mixing barrel to be sucked into the cavity from the first circulation hole 33 on the outer wall of the stirring shaft 3, and then the liquid flows along the cavity under the action of centrifugal force and is sprayed out at high speed from the second circulation hole 311 at the top end of the stirring rod 31. This internal circulation process forms a strong jet flow and a negative pressure area in the local area of the mixing barrel 2, not only strengthening the shear and mixing at the micro level, but also re-raising the solid particles that may be deposited at the bottom and participating in the circulation, so as to realize high-efficiency and homogeneous mixing in a short time, greatly shortening the entire production cycle of the beverage and improving the stability of product quality. The entire device works cooperatively through the above-mentioned multi-layer and multi-mode mixing mechanism, and constitutes a high-efficiency, reliable and widely adaptable composite beverage raw material mixing system.

[0031] It should be noted that the specific model and specifications of the first motor 13, the second motor 221 and the double-head motor 4 need to be determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.
