Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a high-efficiency emulsification and mixing device for low-fat hot pot base. Background Technology

The device includes an emulsifying tank body. Two rotating columns are fixedly provided on the outer peripheral wall of the upper end of the emulsifying tank body.

A water inlet pipe is connected to the upper end of the side wall of the emulsifying tank body.

[0003] The aforementioned comparative documents and existing technologies have the following technical problems: existing hot pot bases mostly use high-fat oils and seasonings mixed and emulsified to ensure the flavor and taste of the base. However, the high fat content can easily lead to excessive oil intake, which is not good for health. Although existing low-fat hot pot bases have reduced oil content, they have problems such as long equipment mixing time, uneven emulsification and high energy consumption in terms of emulsification and mixing efficiency, which cannot meet the needs of large-scale industrial production. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient emulsification and mixing device for low-fat hot pot base.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency emulsification and mixing device for low-fat hot pot base, comprising a base, a pre-emulsification tank on the top of the base, a tank cover on the top of the pre-emulsification tank, a solid feed inlet and a liquid feed inlet on the top of the tank cover, a first filter screen at the inlet of the solid feed inlet, a second filter screen at the inlet of the liquid feed inlet, a conveying pipe on one side of the pre-emulsification tank, and a metering system at the other end of the conveying pipe.

[0006] Preferably, a motor is provided on one side of the metering system, a high-efficiency emulsifying tank is provided at the bottom of the motor, a mixing buffer tank is provided at the bottom of the high-efficiency emulsifying tank, and a support leg and a discharge pipe are provided at the bottom of the mixing buffer tank.

[0007] Preferably, the base has an embedding groove at the top, a pre-emulsification tank is provided inside the embedding groove, and a discharge port is provided on one side of the bottom of the pre-emulsification tank. The discharge port is connected to a conveying pipeline, and the conveying pipeline passes through the metering system to the high-efficiency emulsification tank.

[0008] Preferably, the pre-emulsification tank is equipped with a stirring device at its bottom, a spiral guide plate at its interior, an electrically controlled valve at the port where the pre-emulsification tank connects to the conveying pipeline, and an electrically controlled system at the interior of the base. The electrically controlled system is electrically connected to the electrically controlled valve and to the bottom of the pre-emulsification tank.

[0009] Preferably, the metering system has a feeding port at the top, a display screen on the front, a control button at the bottom of the display screen, a third filter screen at the inlet of the feeding port, the bottom of the feeding port extending to the top of the conveying pipe that runs through the metering system, and the feeding port communicating with the conveying pipe. The metering system has an electronic flow meter inside.

[0010] Preferably, the high-efficiency emulsifying tank is equipped with a high-shear emulsifier inside, and the bottom of the high-efficiency emulsifying tank is provided with a discharge port. The high-shear emulsifier adopts a biaxial staggered shear structure.

[0011] Preferably, the mixing buffer tank has a hollow shaft at its center, a spiral blade on the outside of the hollow shaft, a variable frequency motor at the bottom of the hollow shaft, the mixing buffer tank is connected to the discharge port, and the end of the spiral blade is located at the top of the discharge pipe.

[0012] Beneficial effects This invention employs a pre-emulsification tank, utilizing a spiral guide plate and stirring device designed with fluid dynamics to create a strong vortex during the initial material fall and pumping stage. This not only initially disperses solid materials but also allows water, oil, and powder to be initially and uniformly wetted, avoiding the "clumping" phenomenon in subsequent processing and laying the foundation for efficient emulsification. This premixing speed is faster than that of traditional mixing tanks and is a continuous process.

[0013] This invention employs multiple filter screens and a metering system. The solid and liquid dual inlets and the feeding port are each equipped with multi-stage filter screens. These filter screens have a detachable structure, effectively removing large particulate impurities, ensuring stable material quality, and reducing the risk of wear and blockage in subsequent equipment. The metering system is equipped with an electronic flow meter, a display screen, and control buttons to monitor and adjust the oil-water ratio in real time, reducing errors. Combined with the closed-loop control of the electric valve and the electric control system, it ensures that the formula of each batch of products is stable and consistent.

[0014] This invention employs a high-shear emulsifier with a dual-axis staggered shearing structure. The shearing gap is adaptively adjustable. The structure consists of: an inner rotor mounted on a central shaft, capable of high-speed rotation; an outer rotor fixed to the outer casing or another shaft, typically also capable of rotation, but with a different speed or direction; a shearing chamber: an annular gap formed between the inner and outer rotors, serving as the shearing area; guide grooves and shearing teeth: the rotor surface is equipped with fine shearing teeth or guide grooves to enhance local turbulence intensity; a drive assembly: typically a magnetic levitation motor system to reduce mechanical friction; a shearing gap adjustment mechanism: through sensors and an adaptive control system, the gap width is automatically adjusted according to the fluid viscosity. The working principle: when both rotate at high speed, the material in the shearing chamber experiences periodic high-intensity shear stress, shearing + friction + cavitation: the high speed causes the material to be repeatedly stretched, torn, and impacted between the grooves, simultaneously forming microbubbles to enhance the emulsification and refining effect; gap adjustment function: for formulations with different viscosities or emulsification degrees, the system can automatically adjust the gap between the rotors to control the shearing intensity; nano-emulsification capability: in conjunction with a spray valve or micro-nozzle structure, further breaking down the emulsion particles.

[0015] In this invention, a mixing buffer tank is used. The mixing buffer tank has a hollow shaft with spiral blades and a variable frequency motor for driving. The spiral blades are arranged in a spiral shape around the shaft to form a continuous pushing path. During slow rotation, the emulsion products can be pushed to flow smoothly along the axial direction, effectively preventing stratification and bubble aggregation, achieving buffering and stabilizing of the emulsion products. The material can fall freely or be smoothly pushed along the blades, eliminating bubbles and reducing the damage of turbulence to the emulsion structure, resulting in a more stable output product.

A pre-emulsification tank 2 is provided, with a discharge trough on one side of its bottom. The discharge trough is connected to a conveying pipe 6, which runs through a metering system 7 to a high-efficiency emulsification tank 9. A stirring device 201 is located at the bottom of the pre-emulsification tank 2, and a spiral guide plate 202 is also provided inside. An electrically controlled valve is located at the port where the pre-emulsification tank 2 connects to the conveying pipe 6. An electrical control system is located inside the base 1, and the electrical control system is electrically connected to the electrically controlled valve and the bottom of the pre-emulsification tank 2. A feeding port 701 is located at the top of the metering system 7, and a display screen 702 is located on the front of the metering system 7. A control button 703 is located at the bottom of the display screen 702. A third filter screen 704 is located at the inlet of the feeding port 701. The feed inlet 701 is connected to the top of the conveying pipe 6 that runs through the metering system 7. The metering system 7 is equipped with an electronic flow meter, a display screen 702, and control buttons 703. It monitors and adjusts the oil-water ratio in real time to reduce errors. Combined with the closed-loop control of the electronic control valve and the electronic control system, it ensures that the formula of each batch of products is stable and consistent. The high-efficiency emulsifying tank 9 is equipped with a high-shear emulsifier 901. The bottom of the high-efficiency emulsifying tank 9 is equipped with a discharge port 902. The high-shear emulsifier 901 adopts a dual-axis staggered shear structure. The structure consists of an inner rotor mounted on a central shaft that can rotate at high speed; and an outer rotor fixed on the outer shell or another shaft. It usually also has the ability to rotate, but the speed or direction can be different from that of the inner rotor. Shearing Chamber: An annular gap formed between the inner and outer rotors, serving as the shearing zone; Flow Guides and Shearing Teeth: The rotor surface is equipped with fine shearing teeth or flow guides to improve local turbulence intensity; Drive Component: Typically a magnetic levitation motor system to reduce mechanical friction; Shearing Gap Adjustment Mechanism: Automatically adjusts the gap width based on fluid viscosity using sensors and an adaptive control system. Working Principle: When both rotate at high speed, the material in the shearing chamber experiences periodic high-intensity shear stress. Shearing + Friction + Cavitation: High rotation speed causes the material to be repeatedly stretched, torn, and impacted between the teeth, while simultaneously forming microbubbles to enhance the emulsification and refining effect; Gap Adjustment Function: For formulations with different viscosities or emulsification levels, the system can automatically adjust the gap between the rotors to control the shearing intensity.Nano-emulsification capability: Combined with a spray valve or micro-nozzle structure, it further breaks down emulsified particles. The mixing buffer tank 10 has a hollow shaft 1001 at its center, with spiral blades 1002 on the outer side of the hollow shaft 1001. A variable frequency motor is located at the bottom of the hollow shaft 1001. The mixing buffer tank 10 is connected to the discharge port 902. The end of the spiral blades 1002 is located at the top of the discharge pipe 12. The hollow shaft 1001 of the mixing buffer tank 10, along with the spiral blades 1002 and the variable frequency motor, is driven by the variable frequency motor. The spiral blades 1002 are arranged in a spiral around the shaft, forming a continuous pushing path, which can push the emulsified products along the shaft during slow rotation. The material flows smoothly, effectively preventing stratification and bubble aggregation, thus buffering and stabilizing the emulsion. It allows the material to fall freely and be smoothly propelled along the blades, eliminating bubbles and reducing the damage of turbulence to the emulsion structure, resulting in a more stable output product. A pre-emulsification tank 2 is used, employing a hydrodynamically designed spiral guide plate 202 and a stirring device 201 to create strong vortices during the initial material fall and pumping stages. This not only initially disperses solid materials but also allows for preliminary and uniform wetting of water, oil, and powders, preventing "clumping" in subsequent processing and laying the foundation for efficient emulsification. This is faster than traditional stirred tank premixing and is a continuous process. Specific Implementation Example 2: Reference Figure 6An emulsification chamber and a refining module are added. The emulsification chamber contains a high-pressure pump that accelerates the material through a specially designed Laval nozzle. When the fluid reaches or exceeds the speed of sound, a dramatic pressure and velocity gradient is generated at the nozzle exit, creating a powerful shock wave and shear force. The high-speed fluid carries solid particles that collide with each other and with the chamber walls, pulverizing them to the micron level within milliseconds—far exceeding the efficiency of traditional mechanical grinding. The shock wave generated by the jet instantly tears apart oil droplets and water clumps, forcing them to form extremely small microdroplets, completing the initial, highly efficient emulsification. This process occurs within the chamber, resulting in highly concentrated energy with almost no heat loss or flavor escape. The high-speed jet continuously washes the inner wall, reducing the likelihood of material buildup and scaling, facilitating quick formula changes and cleaning. The emulsified material immediately flows into a ring-shaped or pipe-type... The ultrasonic reactor uses a high-powered ultrasonic transducer array focused at the center of the pipe. The ultrasound generates millions of tiny bubbles, which rapidly form, vibrate, and implode in the sound field, producing localized high temperature, high pressure, and microjets. This "cavitation effect" can "refine" the initially emulsified oil droplets, making their particle size distribution narrower and more uniform, reaching the nanoscale, forming an extremely stable emulsion system. The cavitation effect can also break down plant cell walls, allowing the flavor substances inside to be released more fully and quickly and dissolved into the system. This solves the problem of "lack of aroma" caused by insufficient oil as a flavor carrier in low-fat base ingredients. Compared with traditional heating extraction, ultrasonic extraction is a "cold extraction," which preserves the flavor while avoiding the damage of heat-sensitive substances. The entire process is completed inside the pipe, and the processing time is only a few seconds.

[0022] In summary: 1. The pre-emulsification tank 2 utilizes a spiral guide plate 202 and a stirring device 201 designed with fluid dynamics to create a strong vortex during the initial material fall and pumping. This not only initially disperses solid materials but also allows water, oil, and powder to be initially and uniformly wetted, avoiding the "clumping" phenomenon in subsequent processing and laying the foundation for efficient emulsification. This is faster than the pre-mixing speed of traditional mixing tanks and is a continuous process. 2. Multiple filters and metering system 7 are used to achieve solid and liquid dual inlet and feed port 701 with multi-stage filters. These filters adopt a detachable structure to effectively remove large particulate impurities, ensure stable material quality, and reduce the risk of wear and blockage of subsequent equipment. The metering system 7 is equipped with electronic flow meter, display screen 702 and control button 703 to monitor and adjust oil-water ratio in real time, reduce error. Combined with the closed-loop control of electric valve and electric control system, it ensures that the formula of each batch of products is stable and consistent. 3. The high-shear emulsifier 901, which adopts a dual-axis staggered shearing structure, achieves finer product particle size and improves the smoothness and stability of the taste by using the dual-axis staggered shearing machine inside the high-efficiency emulsification tank 9 under the synergistic effect of adjustable shearing gap, high-speed magnetic levitation rotor and nano-jet valve. 4. The use of the mixing buffer tank 10 enables the spiral blades 1002 to be arranged in a spiral shape around the axis to form a continuous pushing path. During slow rotation, the emulsion products can be pushed to flow smoothly along the axis, effectively preventing stratification and bubble aggregation, achieving buffering and stabilizing of the emulsion products. The material can fall freely or be smoothly pushed along the blades, eliminating bubbles and reducing the damage of turbulence to the emulsion structure, resulting in a more stable output product.
