Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of food production safety, and in particular relates to a self-cleaning mixer used for food production safety. Background Art
[0002] In the processing of raw meat, a staple food, pre-processing requires multiple soaking and cleaning steps to remove surface blood stains, grease, and residual impurities. Traditional cleaning processes often rely on manual kneading combined with static water immersion. This method is labor-intensive and inefficient. Prolonged soaking can also lead to the loss of nutrients and cross-contamination. In recent years, while mechanical agitation and cleaning equipment has gradually replaced manual operations, the following technical bottlenecks have been identified in actual applications.
[0003] Existing mixing equipment generally uses a straight-axis paddle structure. While this can agitate the water, it lacks the ability to directionally separate floating impurities. During the mixing process, lighter impurities such as broken stratum corneum debris, blood foam, and grease tend to form a suspended layer on the water surface. Conventional drain outlets are often located at the bottom of the tank. This causes floating matter to swirl with the water during drainage and reattach to the surface of raw meat products, causing secondary contamination and seriously affecting product cleanliness.
[0004] Therefore, it is necessary to invent a self-cleaning mixer for food safety production to solve the above problems, which can carry out directional separation of floating impurities and avoid secondary contamination of food. Summary of the Invention
[0005] In view of the above problems, the present invention provides a self-cleaning mixer for food safety production to solve the problems raised in the above background technology.
[0006] To achieve the above object, the present invention provides the following technical solution: a self-cleaning mixer for food safety production, comprising a cleaning base, wherein the interior of the cleaning base is connected to a floating object removal mechanism and an air flotation separation mechanism, wherein:
[0007] The cleaning base includes a cleaning rack, the bottom end of which is connected to a support base via a support column, serving as a supporting structure for the entire device. The cleaning base includes a stable cleaning rack for accommodating cleaning liquid and raw meat food to be cleaned;
[0008] The floating object removal mechanism includes a plurality of debris removal racks and a connecting rack in contact with the inner wall of the washing rack, the tops of the plurality of debris removal racks are fixed with a positioning rack, one end of the inner wall of the plurality of debris removal racks is fixed with a positioning ring, the inner walls of the plurality of debris removal racks are clamped with a filter plate through the positioning ring, the bottom ends of the plurality of debris removal racks are fixed with a return spring, the top end of the connecting rack is fixed with a plurality of pressing blocks, and the bottom ends of the plurality of pressing blocks are respectively in contact with the top ends of the plurality of positioning racks;
[0009] A first electric telescopic rod is fixedly provided at the middle position of the support base, and a telescopic end of the first electric telescopic rod is fixedly connected to the middle position of the bottom of the connecting frame;

[0011] A plurality of the debris removal racks are provided with sliding grooves on one side, and the plurality of sides of the inner wall of the cleaning rack are in sliding contact with the inner walls of the plurality of sliding grooves respectively. A positioning groove is provided on the inner wall of the support base, and the outer wall of the connecting rack is in sliding contact with the inner wall of the positioning groove, thereby ensuring the stability of the debris removal rack during movement. In addition, the positioning groove on the inner wall of the support base is in sliding contact with the outer wall of the connecting rack, further enhancing the stability of the structure.
[0012] The floating object removal mechanism consists of multiple debris removal racks and connecting racks. The debris removal racks are in close contact with the inner wall of the cleaning rack, with a positioning rack fixed on the top. A filter plate is engaged with the inner wall through a positioning ring to intercept and collect floating impurities. A reset spring is fixed to the bottom of the debris removal rack, and a pressing block is fixed to the top of the connecting rack, which is in contact with the top of the positioning rack. Under the coordinated action of the debris removal rack reset spring and the first electric telescopic rod, the debris removal rack can perform periodic lifting and lowering movements. When the debris removal rack is pressed down, the liquid level inside it is lower than the liquid level in the main cavity of the cleaning rack, forming a directional liquid level difference. This liquid level difference drives the surface floating objects to flow into the debris removal rack cavity at an accelerated speed. The bottom end of the debris removal rack is equipped with a reset spring, which can automatically reset after completing the debris removal action.
[0013] The air flotation separation mechanism includes an air compressor and a limiting tube.

These bubbles use the hydrophobic properties of impurities to attach to the surface of suspended matter such as stratum corneum debris, blood foam and oil, forming a "bubble-pollutant" complex; because the overall density of the complex is less than that of water, it quickly floats to the liquid surface under the action of buoyancy, forming a scum layer that is easy to collect.

[0026] Technical effects and advantages of the present invention:
[0027] 1. The present invention forms a height difference between the cleaning liquid in the middle of the cleaning rack and the liquid inside the impurity removal rack, so that impurities floating on the top of the cleaning liquid are concentrated and flowed into the inside of the impurity removal rack. The reset spring fixed at the bottom of the impurity removal rack drives the impurity removal rack to reset. In this reciprocating operation, during the soaking and cleaning process, the broken keratin debris, blood foam, grease and other lighter impurities floating on the surface of the cleaning liquid are collected by the impurity removal rack and concentrated on the top of the filter plate inside the impurity removal rack, so that the scum layer quickly formed with the assistance of the air flotation separation mechanism 6 is continuously flowed and cleaned, and the scum layer on the water surface is prevented from being re-attached to the surface of raw meat food with the swirling water during drainage, thereby avoiding secondary pollution and improving the cleaning efficiency of the self-cleaning mixer for food safety production;
[0028] 2. The present invention interconnects the interiors of the rotating seat, connecting tube, connecting seat, and limiting tube, so compressed air is stably output through the air nozzle. Compressed air is injected into the water, releasing 20-100 micron micro-bubbles when the pressure drops suddenly, forming a high-density bubble cluster. The hydrophobic properties of impurities such as stratum corneum debris, blood foam, and grease facilitate the bubbles' attachment to the surface of these impurities, forming a "bubble-pollutant" complex. After the pollutants combine with the bubbles, their overall density is less than that of water, and they quickly float to the liquid surface under the action of buoyancy, forming a scum layer.
[0029] 3. The present invention mechanically couples the stirring and cleaning mechanism with the flotation separation mechanism. Without increasing electrical appliances or energy consumption, the contact synergy of the two mechanisms significantly increases the aggregation rate of the scum layer. The physical contact conduction of kinetic energy replaces the traditional electric drive, reducing equipment manufacturing costs and long-term operating energy consumption.
[0030] 4. The present invention continuously operates a circulating water pump fixed to the outer wall of the cleaning rack, so that the filtered cleaning liquid circulates into the cleaning rack. When floating impurities are continuously removed without changing water or removing sediment, the liquid level in the cleaning rack is always kept balanced, avoiding changes in the liquid level that affect the removal of floating impurities. The filtered cleaning liquid is continuously guided so that the impurity removal rack does not overflow, thereby continuously creating a liquid level difference to handle floating impurities, thereby improving the working convenience of the self-cleaning mixer for food safety production.

DETAILED DESCRIPTION
[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0055] The present invention provides Figure 1-20The self-cleaning mixer for food safety production shown in the figure comprises a cleaning base 1, the interior of which is connected to a floating object removal mechanism 3 and an air flotation separation mechanism 6, wherein:
[0056] The cleaning base 1 includes a cleaning rack 101 , the bottom end of the cleaning rack 101 is connected to an impurity guide rack 102 , and the bottom end of the cleaning rack 101 is connected to a support base 104 via a support column 103 , for containing cleaning liquid and raw meat food to be cleaned.
[0057] As a specific embodiment of the present invention, a stirring and cleaning mechanism 2 is fixedly provided on the top of the cleaning base 1. The stirring and cleaning mechanism 2 drives the raw meat food to roll and rub in the water through the rotation of the stirring shaft 209, thereby accelerating the shedding and dissolution of impurities.
[0058] The stirring and cleaning mechanism 2 includes a support frame 201 fixed to the top of the cleaning frame 101, a second electric telescopic rod 202 is fixed to the top of the support frame 201, a lifting frame 203 is slidably provided on the inner wall of the support frame 201, a fixing frame 206 is fixed to the top of the lifting frame 203, the telescopic end of the second electric telescopic rod 202 is fixedly connected to the top of the fixing frame 206, a reduction motor 207 is fixed inside the fixing frame 206, a positioning shaft 208 is connected to the output end of the reduction motor 207, a stirring shaft 209 is fixed to the bottom end of the positioning shaft 208, an auxiliary plate 210 is fixed to the outer wall of the stirring shaft 209, a limiting ring 211 is fixed to the bottom end of the lifting frame 203, a clamping ring 212 is engaged with the top end of the limiting ring 211, and a cleaning frame 213 is fixed to the middle position of the clamping ring 212;
[0059] Both ends of the top of the lifting frame 203 are fixed with balance bars 204, one end of the outer wall of the two balance bars 204 is connected to the top of the support frame 201, and the top of the two balance bars 204 is fixed with a positioning block 205;
[0060] like Figure 4-Figure 7As shown, when the self-cleaning mixer for food production needs to be used, the cleaning frame 213 containing raw meat food is positioned at the top of the limit ring 211 through the snap ring 212, and the middle position of the bottom of the cleaning frame 213 is connected with the card slot 608, just so that the bottom of the card slot 608 is higher than the top of the cleaning frame 213, and the telescopic end of the second electric telescopic rod 202 fixed to the top of the support frame 201 drives the fixed frame 206 and the lifting frame 203 to rise and fall, and the balance bar 204 fixed to the top of the lifting frame 203 is connected with the support frame 201 through the snap ring 212. The lifting frame 203 drives the cleaning frame 213 to be lifted and lowered stably through the limit ring 211, so that the raw meat food is immersed in the cleaning water in the cleaning frame 101, the positioning shaft 208 is installed and the reduction motor 207 switch is turned on, so that the raw meat food is immersed and slowly stirred and cleaned, so that the broken stratum corneum debris, blood foam and grease and other lighter impurities in the raw meat food are cleaned and separated, and a suspended layer is formed on the surface of the water body, and the heavier impurities are precipitated downward; through the setting of the stirring and cleaning mechanism 2, the raw meat food and the cleaning liquid can also be quickly separated after the cleaning is completed.
[0061] As a specific embodiment of the present invention, the high-pressure air generated by the air compressor 601 in the flotation separation mechanism 6 is transported to the limiting tube 603 through the limiting hose 602, and then stably output to the cleaning liquid through the rotating seat 604, the connecting tube 605 and the air nozzle 606. The high-pressure air is released into the water to form micro-nano bubbles, which adhere to the surface of the suspended matter to form a "bubble-pollutant" complex. The buoyancy of the bubbles rapidly floats to the liquid surface, forming a scum layer.
[0062] The air flotation separation mechanism 6 includes an air compressor 601 and a limiting tube 603. The air outlet of the air compressor 601 is connected to one end of the limiting tube 603 through a limiting hose 602. One end of the limiting tube 603 is rotatably connected to a rotating base 604 through a connecting seat 607. The outer wall of the rotating base 604 is connected to multiple connecting tubes 605. The top of each of the multiple connecting tubes 605 is provided with multiple air nozzles 606.
[0063] like Figures 15-19As shown, the air compressor 601 fixed on the top of the support frame 201 works, so that the high-pressure air is delivered to the interior of the limiting tube 603 through the limiting hose 602. Since the outer wall of the limiting hose 602 passes through the side of the support frame 201 and the lifting frame 203 in turn, the lifting and lowering of the lifting frame 203 will not affect the stable delivery of compressed air. The rotating seat 604 rotates on the outer wall of the connecting seat 607, so the rotating seat 604, the connecting tube 605, the connecting seat 607 and the limiting tube 603 are all connected to each other, so the compressed air is delivered to the interior of the limiting tube 603 through the nozzle. The air nozzle 606 outputs stably, injects compressed air into the water, and releases micro-nano bubbles of 20-100 microns when the pressure drops suddenly, forming a high-density bubble group. The bubbles are small in size, evenly distributed, and have a high specific surface area, which can significantly increase the probability of contact with pollutants. The hydrophobic properties of impurities such as stratum corneum debris, blood foam and oil are utilized to facilitate the attachment of bubbles to the surface of stratum corneum debris, blood foam and oil suspension, forming a "bubble-pollutant" complex. After the pollutants combine with the bubbles, the overall density is less than that of water. Under the action of buoyancy, they quickly float to the liquid surface to form a scum layer.
[0064] A slot 608 is fixedly provided at the top of the rotating seat 604, and a buckle 609 is fixedly provided at the middle position of the bottom of the stirring shaft 209. The slot 608 and the buckle 609 are engaged and connected;
[0065] like Figure 20 As shown, before the positioning shaft 208 and the stirring shaft 209 are connected to the output end of the reduction motor 207, the buckle 609 fixed at the bottom end of the stirring shaft 209 is engaged with the slot 608 at the top end of the rotating seat 604, and the depth of the slot 608 is large, so that the positioning shaft 208 can be adjusted during installation. When the slot 608 is engaged with the buckle 609, when the stirring shaft 209 rotates, the rotating seat 604 rotating at the top end of the connecting seat 607 drives the connecting pipe 605 and the air nozzle 606 to rotate synchronously, so that the compressed air is output upward in a rotating manner, thereby increasing the contact area between the bubbles and impurities such as stratum corneum debris, blood foam and grease, significantly expanding the bubble coverage area, and facilitating the rapid formation of a "bubble-pollutant" complex.
[0066] By mechanically coupling the stirring and cleaning mechanism 2 with the flotation separation mechanism 6, the contact synergy of the two mechanisms is utilized to significantly increase the aggregation rate of the scum layer without increasing electrical appliances or energy consumption. The kinetic energy is transmitted through physical contact instead of traditional electric drive, thereby reducing equipment manufacturing costs and long-term operating energy consumption.
[0067] As a specific embodiment of the present invention, the debris removal frame 301 of the floating object removal mechanism 3 is in close contact with the inner wall of the cleaning frame 101. A positioning frame 303 is fixed to the top, and a filter plate 305 is engaged with the inner wall through a positioning ring 304 to intercept and collect floating impurities. A return spring 306 is fixed to the bottom of the debris removal frame 301, and a pressing block 308 is fixed to the top of the connecting frame 302, which contacts the top of the positioning frame 303. The connecting frame 302 is driven to rise and fall by the first electric telescopic rod 310, which drives the debris removal frame 301 to perform periodic lifting and lowering motion, forming a directional liquid level difference, driving the surface floating matter to flow into the cavity of the debris removal frame 301.
[0068] The floating object removal mechanism 3 includes a plurality of debris removal frames 301 and a connecting frame 302 in contact with the inner wall of the cleaning frame 101. The tops of the plurality of debris removal frames 301 are fixed with positioning frames 303. One end of the inner wall of the plurality of debris removal frames 301 is fixed with a positioning ring 304. The inner walls of the plurality of debris removal frames 301 are all engaged with filter plates 305 through the positioning ring 304. The bottom ends of the plurality of debris removal frames 301 are fixed with return springs 306. The bottom ends of the plurality of return springs 306 are fixedly connected to the bottom end of the inner wall of the cleaning frame 101. The top of the connecting frame 302 is fixed with a plurality of pressing blocks 308. The bottom ends of the plurality of pressing blocks 308 are respectively in contact with the tops of the plurality of positioning frames 303.
[0069] A sliding groove 307 is formed on one side of each of the plurality of debris removal racks 301. The sides of the inner wall of the cleaning rack 101 are in sliding contact with the inner walls of the plurality of sliding grooves 307. A positioning groove 105 is formed on the inner wall of the support base 104. The outer wall of the connecting rack 302 is in sliding contact with the inner wall of the positioning groove 105.
[0070] A first electric telescopic rod 310 is fixedly provided in the middle of the support base 104, and the telescopic end of the first electric telescopic rod 310 is fixedly connected to the middle position of the bottom of the connecting frame 302;
[0071] like Figure 8 、 Figure 9 and Figure 11-14As shown, the telescopic end of the first electric telescopic rod 310 fixed at the middle position of the support base 104 drives the connecting frame 302 to be intermittently raised and lowered, so that the lifting frame 203 slides along the positioning groove 105 provided on the inner wall of the support base 104, so that the connecting frame 302 drives the pressing block 308 fixed at the top to press the positioning frame 303 downward, so that the positioning frame 303 drives the debris removal frame 301 to move downward, and the sliding positioning of the sliding groove 307 provided on one side of the debris removal frame 301 makes the debris removal frame 301 move downward. When the debris removal frame 301 is pressed, the top height of the debris removal frame 301 is lower than the cleaning liquid inside the cleaning frame 101, so that the cleaning liquid in the middle of the cleaning frame 101 and the liquid inside the debris removal frame 301 form a height difference, so that impurities floating on the top of the cleaning liquid are concentrated and flowed to the debris removal frame. Inside the frame 301, the connecting frame 302 is released by pressing for a moment, so that in a natural state, the return spring 306 fixed at the bottom end of the debris removal frame 301 drives the debris removal frame 301 to reset, so that the height of the top end of the debris removal frame 301 is higher than the cleaning liquid. In this reciprocating operation, during the soaking and cleaning process, the broken cuticle debris, blood foam, grease and other lighter impurities floating on the surface of the cleaning liquid are collected by the debris removal frame 301 and concentrated on the top end of the filter plate 305 inside the debris removal frame 301, so that the scum layer quickly formed with the assistance of the air flotation separation mechanism 6 is continuously flowed and cleaned, thereby preventing the scum layer on the water surface from being re-attached to the surface of the raw meat food with the swirling water flow during drainage, avoiding secondary pollution, and improving the cleaning efficiency of the self-cleaning mixer for food safety production;
[0072] like Figure 1-Figure 3 As shown, the debris removal rack 301 adopts a three-part layout scheme, and the standard configuration is that three units are evenly distributed along the circumference of the inner wall of the cleaning rack 101. This structural design can achieve an operation coverage of 120° phase angle, significantly improving the cleaning efficiency of the scum layer. In actual engineering applications, the configuration quantity can be expanded according to material processing requirements. Multiple debris removal racks 301 will be evenly arranged along the circumference of the inner wall of the cleaning rack 101 to form a continuous cleaning system surrounding the outer wall of the cleaning frame 213. By increasing the density of the debris removal racks, the scraping area coverage rate can be effectively improved, ensuring the integrity of the scum layer removal and the continuity of the operation, while reducing the single-point mechanical load and extending the service life of the equipment.
