Description

Technical Field

[0001] This utility model relates to the field of colloid mill equipment technology, specifically to a colloid mill device for calcium beverage production with integrated defoaming function. Background Technology

[0002] A colloid mill is a device used for fine grinding and dispersion of materials. In the production of calcium beverages, it can grind solid materials such as calcium sources into extremely fine particles, allowing them to be evenly dispersed in a liquid medium, thereby improving the solubility and absorption rate of calcium, while also improving the taste and stability of the beverage.

[0003] During the production of calcium-rich beverages, a large amount of foam is easily generated due to the stirring, conveying, and contact with air of the materials. For example, when grinding materials using a colloid mill, the high-speed rotation causes air to mix into the materials, thus triggering foam formation. In addition, some components in calcium-rich beverages, such as proteins and surfactants, can also increase the stability of the foam.

[0004] Traditional colloid mills primarily focus on grinding and dispersing materials, lacking effective defoaming methods. This necessitates the installation of separate defoaming equipment in subsequent production processes, increasing the complexity of the production process and equipment investment costs. Utility Model Content

[0005] The purpose of this invention is to design a colloid mill device for producing calcium beverages with integrated defoaming function, in order to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a colloid mill device for producing calcium beverages with integrated defoaming function, comprising a base, a defoaming module, a grinding body fixed to the base, and a hopper fixed to the top of the grinding body. The grinding body includes a first motor, a stator, and a rotor fixed to the output end of the first motor. The cavity between the rotor and the stator forms a grinding chamber, which is connected to the hopper. The defoaming module includes a defoaming chamber, which is connected to the grinding chamber through a first discharge pipe.

[0007] Furthermore, the defoaming module also includes a vacuum pump, which is connected to the defoaming chamber.

[0013] Furthermore, the inner wall of the stator is coated with a hydrophobic coating.

[0014] Furthermore, the bottom of the grinding chamber is inclined.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Example: Please refer to Figure 1-3A colloid mill device for producing calcium beverages with integrated defoaming function includes a base 1, a defoaming module 3, a grinding body 2 fixed to the base 1, and a hopper 4 fixed to the top of the grinding body 2. The hopper 4 facilitates the addition of raw materials. The grinding body 2 includes a first motor 21, a stator 22, and a rotor 23 fixed to the output end of the first motor 21. The cavity between the rotor 23 and the stator 22 forms a grinding chamber 5, which is connected to the hopper 4. The defoaming module 3 includes a defoaming chamber 31, which is connected to the grinding chamber 5 through a first discharge pipe 6. This invention uses food-grade stainless steel for the grinding body 2 in the calcium beverage production process to ensure that no harmful substances are released during grinding, thus preventing contamination of the calcium beverage. The surfaces of the rotor 23 and stator 22 that come into contact with the calcium beverage are coated with special coatings or materials, such as epoxy resin coatings or polytetrafluoroethylene coatings, to effectively prevent corrosion from highly acidic calcium beverages. The first discharge pipe 6 is equipped with a second control valve 7. After the rotor 23 fully grinds the calcium beverage raw materials in the grinding chamber 5, the second control valve 7 is opened, allowing the material to be conveyed from the grinding chamber 5 to the defoaming chamber 31, where it is fully defoamed. Both ends of the first discharge pipe 6 are sealed to the outlet of the grinding chamber 5 and the inlet of the defoaming chamber 31 via flanges, forming a continuous processing channel. This achieves seamless connection between the grinding chamber 5 and the defoaming chamber 31, eliminating the need for a separate defoaming device, simplifying the production process, and reducing equipment investment costs.

[0022] In an optional embodiment, the defoaming module 3 further includes a vacuum pump, which uses vacuum negative pressure to break up bubbles. After the vacuum pump is connected to the defoaming chamber 31, the air pressure in the defoaming chamber 31 is typically -0.08 to -0.1 MPa. The material stays in the defoaming chamber 31 for 5-10 seconds before being discharged, which can reduce the foam volume by 85% and increase production efficiency by 2 times.

[0023] In an optional embodiment, the defoaming module 3 further includes a driving component and a rotating component fixed to the output end of the driving component. The rotating component is disposed within the defoaming chamber 31, and an exhaust port is provided at the top of the defoaming chamber 31. The centrifugal force generated by the rotation of the rotating component causes gas-liquid separation. The driving component is preferably a second motor, and the rotating component is preferably a stirring shaft fixed to the output end of the second motor and spiral blades fixed to the stirring shaft. The stirring shaft is driven to rotate by the second motor, with a rotation speed of 1500-2000 rpm. The spiral blades stir and defoam the material, and the bubbles are discharged through the top exhaust port. The defoaming rate of this embodiment can reach 92%, and the energy consumption is reduced by 35% compared with traditional homogenizers.

[0024] In an optional embodiment, the defoaming module 3 further includes an ultrasonic vibration component, which comprises a high-power ultrasonic transducer and an amplitude transformer. The transmitting head of the ultrasonic vibration component is connected to the interior of the defoaming chamber 31. The ultrasonic transducer converts electrical energy into mechanical energy, i.e., ultrasonic waves, and performs longitudinal telescopic motion; the amplitude transformer amplifies the amplitude, isolates the reaction solution from the transducer, and fixes the entire system; the tool head emits ultrasonic energy into the liquid. Defoaming using the ultrasonic vibration component can rapidly destroy foam in a short time. By utilizing high-frequency vibration and cavitation effects, it generates high local shear force and pressure waves, resulting in rapid defoaming. Furthermore, ultrasonic defoaming can be performed simultaneously with vacuum defoaming or centrifugal defoaming in the above embodiments, which can further improve the defoaming efficiency.

[0025] In an optional embodiment, a cooling water tank 8 is also included. The cooling water tank 8 is disposed on the outer wall of the grinding chamber 5. The water pump of the cooling water tank 8 circulates the water. The water in the cooling water tank 8 directly contacts the outer wall of the grinding chamber 5, which can effectively control the temperature inside the grinding chamber 5, thereby reducing the generation of foam.

[0026] In an optional embodiment, an intelligent control system (not shown in the figure) is also included. This system includes a sensor for detecting the amount of foam and is capable of regulating the operation of the device, for example, automatically adjusting the speed of the second motor or the negative pressure intensity of the vacuum pump. Specifically, the intelligent control system is prior art and will not be described in detail here.

[0027] In the above embodiment, the defoaming chamber 31 is connected to a second discharge pipe 9, and a first control valve 10 is installed on the second discharge pipe 9. The first control valve 10 is connected to a return pipe 11, and the output end of the return pipe 11 is connected to the hopper 4. If the sensor detects that there is too much foam in the material, the first control valve 10 controls the flow direction of the material, so that the material is transported from the return pipe 11 to the hopper 4, and then the material is transported from the grinding chamber 5 to the defoaming chamber 31 for repeated defoaming.

[0028] In an optional embodiment, the inner wall of the stator 22 is coated with a hydrophobic coating to reduce bubble adhesion.

[0029] In an optional embodiment, the bottom of the grinding chamber 5 is inclined to reduce the residue of air bubbles.

[0030] The working principle of this invention is as follows: When producing calcium beverages, the first motor 21 is started, and the calcium beverage raw materials are added to the hopper 4. After the materials flow into the grinding chamber 5, the rotor 23 grinds the calcium beverage raw materials in the grinding chamber 5 to generate the corresponding material. After sufficient grinding, the second control valve 7 is opened, and the material is transported along the first discharge pipe 6 to the defoaming chamber 31, where the material is fully defoamed. The grinding body 2 and the defoaming chamber 31 are connected as a whole through the first discharge pipe 6. Grinding and defoaming are a continuous production process, eliminating the need for a separate defoaming device, simplifying the production process, and reducing equipment investment costs.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
