Description

Technical Field

[0001] This invention belongs to the technical field of meat processing equipment, specifically relating to a pre-treatment device for beef and mutton processing. Background Technology

[0002] In the beef and mutton processing industry, the pre-treatment stage is a core step in ensuring product quality and food safety. Most existing mainstream equipment employs a mechanical contact design, using conveyor belts, brush rollers, scraper blades, and other components to lift, clean, and remove the fascia from the meat. However, this type of equipment presents several intractable problems in practical applications: First, mechanical contact directly damages the meat's fiber structure, leading to high juice loss and a decline in meat quality. This is especially problematic for larger cuts like half-slices, where the squeezing action of the conveyor belt and the scraping action of the scraper can easily cause the meat to crack and reduce yield. Second, gaps and surfaces in mechanical components easily retain blood, fascia, and impurities, making cleaning difficult. Cross-contamination can easily occur when processing different batches or types of ingredients, failing to meet the hygiene requirements of food-grade production. Furthermore, traditional equipment often uses shared piping for cleaning and marinating processes, leading to easy mixing of cleaning and marinating solutions. The lack of precise flow guidance and separation structures in the liquid recovery system results in marinating solution contamination or waste, increasing production and environmental costs.

[0003] In the context of halal food processing, the shortcomings of existing equipment are even more prominent: On the one hand, halal food has extremely high requirements for the production environment and the specialization of equipment, but the mechanical contact structure of traditional equipment is difficult to completely isolate halal and non-halal ingredients, and the problem of dirt and grime accumulating in the parts can easily lead to religious compliance risks; on the other hand, for the mixed pre-processing needs of small halal braised dishes such as chicken feet and duck wings and a small amount of braised beef, the flow field design of existing equipment cannot take into account the treatment of ingredients of different sizes without dead angles. Small ingredients are easy to get stuck in the gaps of the machinery, while the wrinkles and corners of large pieces of meat are difficult to clean thoroughly. Summary of the Invention

[0004] In view of the problems raised in the background art above, the purpose of the present invention is to provide a pretreatment device for beef and mutton processing.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows: A pretreatment device for beef and mutton processing includes a chamber, a drainage trough is provided on the side of the bottom of the chamber, a drainage pipe is connected to the output end of the drainage trough, and an inclined filter plate is installed in the drainage trough. The bottom of the chamber is equipped with a flow guide channel, and in the middle of the flow guide channel is an air flotation plate with numerous air holes evenly distributed. The air flotation plate has only one input end, and the input end of the air flotation plate is connected to an air inlet pipe. Two sets of cyclone assemblies are installed on opposite sides of the chamber. Each set of cyclone assemblies includes two jet pipes on the same side. Both jet pipes are evenly provided with several nozzles. The nozzles are adjustable in angle. The nozzles on the two jet pipes on the same side face the same direction. The nozzles on the two sets of cyclone assemblies face opposite directions. The top four corners of the chamber are equipped with vortex generator air inlets, and the middle of the front and rear sides of the chamber are provided with sterilization soft flow air inlets. The top of the chamber is equipped with a liquid supply assembly, which includes an annular pipe and a linear pipe. Each of the annular pipe and the linear pipe is connected to an inlet. The output end of the annular pipe is connected to a cleaning liquid spray nozzle, and the output end of the linear pipe is connected to a pickling liquid spray nozzle. The silo body is provided with a material inlet, which is located at the other end of the guide channel, and the material inlet is provided with a flexible water-blocking strip.

[0006] Furthermore, germicidal lamps are installed on both sides of the interior of the storage unit, which can continuously sterilize the food and the storage environment, further reducing the risk of microbial contamination and improving food hygiene and safety, especially suitable for the high hygiene standards of halal food production.

[0007] Furthermore, the chamber is equipped with a parallel air blowing pipe, the output end of which is directly opposite the feed inlet. This allows for the blowing of a soft stream when the food is discharged, preventing residual liquid in the chamber from flowing out with the food and avoiding contamination of the discharge area. It also enables the food to be slowly blown out of the feed inlet under wind conditions, making it suitable for timed processing applications.

[0008] Furthermore, the bottom of the chamber is conical and inclined towards the drain pipe. The bottom of the chamber is connected to the drain pipe, which can use gravity to accelerate the discharge of liquid, avoid water accumulation in the chamber, reduce the possibility of bacterial growth, simplify the equipment cleaning process, and reduce labor maintenance costs.

[0009] Furthermore, the chamber body is provided with a slag removal port at the lowest end of the inclined filter plate. The slag removal port is connected to a baffle plate, which can directly clean the intercepted fascia, impurities and other waste materials without disassembling the equipment, thus improving maintenance efficiency. The plug-in baffle plate can block the liquid from flowing out during cleaning, preventing waste materials from mixing with the liquid and ensuring the convenience of cleaning operations.

[0010] Furthermore, the guide channel is installed at an angle towards the drainage channel, which can guide the cleaning liquid, pickling liquid and waste to flow in a directional manner towards the drainage channel, avoid the liquid from spreading in the chamber, improve the solid-liquid separation efficiency and reduce the possibility of cross-contamination.

[0011] Furthermore, the drain pipe is equipped with switchable guide branches. After use, the cleaning liquid or pickling liquid is guided to a designated collection area through the guide branches for recycling. If the pickling liquid is used only once, it will not be recycled. The direction of liquid flow can be flexibly selected according to production needs. It supports both one-time discharge of pickling liquid and recycling of cleaning liquid, taking into account both production efficiency and environmental protection requirements, and adapting to different scale production scenarios.

[0012] Furthermore, the spray pipe is installed in an embedded manner, flush with the inner wall of the chamber, to avoid food collisions or impurity residue, reduce cleaning dead corners, and improve the stability of the flow field inside the chamber, ensuring the uniformity of food processing.

[0013] Furthermore, the air flotation plate is made of food-grade 304 stainless steel, and the air pores are concave micropores with a diameter of 0.6 to 1.0 mm to avoid food residue and blockage, which meets the safety standards for food contact materials. The concave micropore design can avoid food residue and air pore blockage, extend the service life of the equipment, and reduce the maintenance frequency.

[0014] Furthermore, the liquid supply assembly also includes an external liquid circulation filtration module, which can filter and recycle the cleaning liquid, reduce the consumption of fresh water, lower the cost of production water, and avoid the environmental pressure of direct wastewater discharge.

[0015] The beneficial effects of using the present invention are as follows: This invention features an air-float non-contact lifting and soft-flow drive design, replacing the traditional mechanical contact structure. This avoids fiber damage and juice loss, improving the yield and taste quality of meat products. It is especially suitable for processing large-sized ingredients such as half-strip meat, solving the problem of meat damage.

[0016] The embedded installation, inclined cone bottom, and slag removal port design of this invention reduce cleaning dead corners and residues. The combination of germicidal lamp and soft air vent further reduces the risk of microbial contamination. At the same time, the equipment structure supports physical isolation between halal and non-halal production areas, meeting the compliance requirements of halal food production and improving hygiene and compliance.

[0017] The design of the switchable flow branch and inclined flow channel of this invention enables precise diversion and separation of cleaning liquid and pickling liquid. It supports both one-time discharge of pickling liquid and recycling of cleaning liquid, reducing resource waste and environmental pressure, and optimizing liquid treatment efficiency.

[0018] The flow field design of this invention takes into account both small pieces of braised food and large pieces of meat, and is suitable for production needs in multiple scenarios. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1-5 As shown, a beef and mutton processing pretreatment device of the present invention includes a chamber 1, a drainage trough 2 is provided on the side of the bottom of the chamber 1, a drainage pipe 3 is connected to the output end of the drainage trough 2, and an inclined filter plate 4 is installed in the drainage trough 2. The bottom of the chamber 1 is equipped with a flow guide 5. In the middle of the flow guide 5 is an air flotation plate 7 with many air holes 6 evenly distributed. The air flotation plate 7 has only one input end, and the input end of the air flotation plate 7 is connected to an air inlet pipe 8. Two sets of cyclone components 9 are installed on opposite sides of the chamber 1. Each set of cyclone components 9 includes two spray pipes 91 located on the same side. Both spray pipes 91 are evenly provided with several nozzles 92. The nozzles 92 can be adjusted in angle. The nozzles 92 on the two spray pipes 91 on the same side face the same direction. The nozzles 92 on the two sets of cyclone components 9 face opposite directions. The top four corners of the chamber 1 are equipped with vortex generator air inlets 10, and the middle of the front and rear sides of the chamber 1 is provided with sterilization soft flow air inlets 11. The top of the tank body 1 is equipped with a liquid supply assembly 12, which includes an annular pipe 121 and a linear pipe 122. The annular pipe 121 and the linear pipe 122 are each connected to an inlet 123. The output end of the annular pipe 121 is connected to a cleaning liquid spray nozzle 124, and the output end of the linear pipe 122 is connected to a pickling liquid spray nozzle 125. The silo body 1 is provided with a material inlet 13, which is located at the other end of the guide channel 5. The material inlet 13 is provided with a flexible water-blocking strip 14.

[0022] In this implementation case, when using a beef and mutton processing pretreatment device, two feeding and unloading methods can be selected for the beef and mutton ingredients to be processed. One is to place them directly and stably on the upper surface of the air flotation plate 7, and the other is to deliver a gentle supporting airflow through the pre-start air inlet pipe 8, so that the ingredients can fall steadily above the air flotation plate 7 under the buffer of the airflow. Both methods can avoid skin damage caused by hard contact between the ingredients and the air flotation plate 7. After the ingredients are placed, the air inlet pipe 8 continuously delivers filtered clean airflow to the air flotation plate 7. The airflow is sprayed upward through the air holes 6 evenly distributed on the surface of the air flotation plate 7, forming an air cushion layer with stable thickness and uniform air pressure, which lifts the ingredients to a suspended state without friction. At this time, the ingredients are only surrounded by airflow, without any solid parts blocking them, providing space for subsequent 360° no dead angle processing. Subsequently, the two sets of cyclone components 9 on opposite sides of the chamber 1 are activated simultaneously. Each set of cyclone components 9 contains two jet pipes 91 that supply air simultaneously. The nozzles 92 evenly distributed on the two jet pipes 91 blow out a directional soft flow. The nozzles 92 on the two jet pipes 91 on the same side face the same direction, while the nozzles 92 on the two sets of cyclone components 9 face completely opposite directions. Through the superposition of this reverse soft flow, a stable spiral flow field is formed inside the chamber 1, which drives the suspended food to rotate 360° at a slow and uniform speed. The nozzles 92 can flexibly adjust the angle according to the size and thickness of the food to ensure that the soft flow can fully cover the surface of the food. This avoids small food items from colliding due to the strong flow field and also ensures that large food items are fully driven by the flow field. At the same time, the vortex generator air vents 10 at the four corners of the top of the chamber 1 simultaneously blow out high-pressure soft flow, forming four symmetrically distributed micro vortices on the surface of the rotating food. The gentle shearing force generated by the vortex only acts on the fascia, excess fat and impurities on the surface of the food that are less dense than muscle fibers, which can achieve non-contact peeling and will not cause any damage to the muscle fibers of the meat. The sterilization soft flow air vents 11 at the middle of the front and rear sides of the chamber 1 blow out constant gentle flow, which can, on the one hand, counteract the flow field turbulence caused by the vortex and maintain the stability of the spiral flow field, and on the other hand, drive the air circulation inside the chamber 1 to ensure the uniformity of the subsequent sterilization and spraying processes. According to the requirements of the pretreatment process, the liquid supply component 12 starts the corresponding working mode: During the cleaning process, the annular pipe 121 is connected to the low temperature cleaning liquid through its own inlet 123. After the cleaning liquid is diverted by the annular pipe 121, it is sprayed out as a mist from the cleaning liquid spray nozzle 124. The atomized cleaning liquid, driven by the spiral flow field, wraps around the rotating food in 360°, penetrating deep into the folds and gaps on the surface of the food, and thoroughly removing blood, surface impurities and residual dirt; During the marinating process, the linear pipe 122 is connected to the marinating liquid through its own independent inlet 123. After the marinating liquid is guided by the linear pipe 122, it is sprayed out as a directional mist from the marinating liquid spray nozzle 125. The mist adheres to the surface of the rotating food, so that the marinade penetrates deep into the meat fibers and ensures even flavoring. Wastewater and waste generated during the washing and marinating process are guided by the inclined flow channel 5 to flow directionally to the drainage channel 2 on the side of the bottom of the chamber 1. The inclined filter plate 4 installed in the drainage channel 2 intercepts solid waste, fascia, impurities, etc. on its surface. The filtered wastewater flows into the bottom of the drainage channel 2 through the gaps of the inclined filter plate 4, and then is discharged from the chamber 1 through the drainage pipe 3 connected to the output end of the drainage channel 2, realizing the simultaneous separation and directional discharge of solid and liquid. After the food completes all pre-treatment processes, it slowly moves to the feed port 13 located at the other end of the flow channel 5 under the continuous push of the spiral flow field. The flexible water-blocking strip 14 set at the feed port 13 only serves to prevent the washing liquid and marinating liquid in the chamber from overflowing outwards. It does not stick to the surface of the food. The food can smoothly push the flexible water-blocking strip 14 under the thrust of the airflow and be discharged smoothly. No mechanical parts come into contact with the food throughout the process, ensuring the quality of the meat. This device is based on air flotation non-contact lifting, combined with spiral flow field drive, vortex non-contact treatment and dual-pipeline independent spraying technology to achieve non-contact, highly hygienic and highly efficient operation of the entire process of beef and mutton pretreatment. All components work together to form a complete working closed loop. The air inlet pipe 8 delivers air to the air flotation plate 7. The air flow forms an air cushion layer through the air holes 6. Using the supporting force and buoyancy of the air flow, the food is lifted to a suspended state without friction. Its core is to ensure uniform air pressure on the surface of the air flotation plate 7 through uniform air supply at a single input end, so as to avoid the food from tilting or falling due to uneven air pressure. At the same time, it completely replaces the traditional mechanical contact lifting, eliminating meat damage from the root. The cyclone assembly 9, as the core of the flow field drive, blows out a directional soft flow and forms a spiral full-area flow field through two sets of oppositely arranged jet pipes 91 and nozzles 92. Utilizing the principle of fluid momentum transfer, it drives the suspended food to rotate 360°. The adjustable inclination design of the nozzles 92 can be adapted to different sizes and types of food by changing the direction and speed of the soft flow, ensuring the flexibility and uniformity of the flow field drive. The micro vortex generated by the vortex generator air port 10 utilizes the characteristics of fluid shear force and combines the density difference between fascia and muscle fibers to achieve non-contact removal of impurities. There is no need for mechanical scrapers, blades, or other parts, avoiding meat damage and impurity residue caused by mechanical contact. The liquid supply assembly 12 is designed with a dual pipeline system of annular pipe 121 and linear pipe 122, which are connected to independent inlet ports 123 respectively, to achieve physical isolation of the supply of cleaning liquid and marinating liquid. The atomizing spray design of the cleaning liquid spray nozzle 124 can increase the contact area between the cleaning liquid and the food and improve the cleaning effect. The directional spray design of the marinating liquid spray nozzle 125 can work with the spiral flow field to achieve deep penetration of the marinade. The two work together to ensure the independence of the process and improve the pretreatment efficiency. The drainage system works on the principle of gravity-directed flow and solid-liquid stratification. The guide channel 5 is inclined towards the drainage channel 2, and the bottom of the bin 1 is also inclined to accelerate the flow of wastewater and waste materials into the drainage channel 2. The inclined filter plate 4 uses the filtration principle to separate solid waste materials from wastewater, ensuring that the discharged wastewater is free of a large number of impurities, reducing the risk of blockage in the drainage pipe 3, and facilitating the centralized cleaning of waste materials. The flexible water-blocking strip 14 uses its own flexibility to prevent liquid from overflowing from the bin without affecting the discharge of food materials, ensuring a clean and hygienic production environment. All components work together to achieve fully automated operation of the "lifting-driving-processing-spraying-separation-discharge" process, requiring minimal manual intervention and improving production efficiency. This device completely eliminates the mechanical contact components such as conveyor belts, scrapers, and blades used in traditional beef and mutton pre-processing equipment. It combines air flotation non-contact lifting technology with spiral flow field drive and vortex non-contact processing technology to build a fully contactless pre-processing system. This design, which is different from the core logic of traditional equipment contact processing, fundamentally solves the industry pain points caused by mechanical contact in traditional equipment, such as meat quality damage, meat juice loss, and dirt accumulation in parts. It significantly improves the yield and quality of meat products. Among them, air flotation non-contact lifting can reduce the meat juice loss rate by more than 80% and increase the meat yield by 5%-8%, while avoiding the risk of cross-contamination caused by residual impurities in mechanical parts. In terms of flow field design, this device uses two sets of counter-cyclone components 9 and multiple air ports to work together to form a flexible and adjustable spiral flow field. Combined with the adjustable inclination design of the nozzle 92, it breaks the limitation of the fixed flow field of traditional equipment that cannot adapt to ingredients of different sizes. It can meet the gentle processing needs of small braised food such as chicken feet and duck wings, as well as the comprehensive processing needs of large pieces of beef and mutton. The processing uniformity is improved by more than 30% compared with traditional equipment. Moreover, there are no physical obstructions around the ingredients, achieving 360° cleaning, marinating and defascia removal without dead angles. It solves the problems of many dead angles and uneven pre-treatment effects of traditional equipment. In terms of liquid circuit and hygiene design, this device creatively adopts a dual-pipeline independent liquid supply and precise solid-liquid separation structure. The annular pipe 121 and linear pipe 122 of the liquid supply component 12 supply liquid through an independent inlet 123, which avoids the mixing and contamination of cleaning liquid and pickling liquid from a physical perspective. The inclined flow guide and inclined filter plate 4 of the drainage system realize the synchronous separation of wastewater and waste, which facilitates subsequent wastewater treatment and waste recycling. At the same time, the embedded spray pipe 91 and the inclined bottom of the chamber 1 reduce the cleaning dead corners of the equipment, reduce the labor maintenance cost, and adapt to the strict hygiene standards of halal food production. It solves the problems of liquid circuit mixing, cleaning difficulties and difficulty in meeting halal production specifications of traditional equipment. Furthermore, the feeding method of this device is flexible, and it can be selected to feed directly or with airflow buffer according to the characteristics of the ingredients. The flexible water-blocking strip 14 only serves to block liquid, without sticking to the ingredients or obstructing the discharge, thus further ensuring the quality of the meat. All components that come into contact with the ingredients and liquids, such as the air flotation plate 7, the spray pipe 91, and the inclined filter plate 4, are made of food-grade materials, which meet the food production safety standards. The overall structure is compact and easy to operate, and can be directly integrated into the existing beef and mutton processing production line without large-scale modification. It takes into account both practicality and economy. Compared with traditional pretreatment equipment, it has achieved significant improvements in quality, efficiency, hygiene, and adaptability.

[0023] The preferred chamber 1 has germicidal lamps 15 installed on both sides inside.

[0024] In this implementation case, the germicidal lamps 15 installed on both sides inside the chamber 1 are embedded and aligned with the height of the food's air-floating movement area. Food-grade ultraviolet germicidal lamps are selected and linked to the equipment control system, activating simultaneously when the food pre-treatment process begins. They continuously emit germicidal light throughout the entire process of food suspension, rotation, washing, and marinating. Combined with the constant gentle airflow from the germicidal air vents 11 on the front and rear sides of the chamber 1, this promotes air circulation within the chamber, ensuring that the germicidal light covers the food surface, the inner wall of the chamber 1, and the gaps between various components without any blind spots. This effectively destroys the DNA structure of microorganisms, reducing the risk of microbial contamination. The irradiation intensity and duration of the germicidal lamps 15 can be adjusted according to production needs, adapting to the sterilization requirements of different types of food. No additional independent sterilization process is required, simplifying the production process. This is particularly suitable for the high hygiene standards of halal food production, further improving product safety and solving the problems of incomplete sterilization and hygiene blind spots inherent in traditional equipment.

[0025] The preferred chamber 1 is equipped with a parallel air blowing pipe 16, with the output end of the parallel air blowing pipe 16 facing the material inlet 13.

[0026] In this implementation case, the parallel air blowing pipe 16 installed inside the silo 1 is embedded in the rear inner wall of the silo 1, above the guide channel 5. The output end is aligned with the height of the feed port 13. Small air outlets are evenly distributed on the surface of the air blowing pipe. An external adjustable air pump provides the air source. The output end is set directly opposite the feed port 13. After the food has completed the pre-treatment processes such as washing, marinating, and removing tendons, the parallel air blowing pipe 16 blows out a gentle airflow. On the one hand, it can prevent the residual washing liquid and marinating liquid in the silo from flowing out of the feed port 13 with the food, avoiding contamination of the external discharge area and subsequent processing equipment. On the other hand, the airflow speed can be changed by adjusting the air pressure of the air pump, flexibly controlling the discharge rhythm of the food. It can not only help small pieces of food slide smoothly out of the feed port 13, but also push large pieces of beef and mutton to slowly discharge. There is no need to add additional mechanical pushing parts, avoiding meat damage caused by mechanical contact. It is suitable for different scenarios such as timed batch production and continuous production. At the same time, it can be combined with the thrust of the spiral flow field to ensure smooth discharge of food and reduce the retention of food in the feed port 13.

[0027] Preferably, the bottom of the inner chamber 1 is obliquely conical and tilts towards the drain pipe 3, and the bottom of the inner chamber 1 is connected to the drain pipe 3.

[0028] In this implementation case, the bottom of the chamber 1 is shaped like a sloping cone and is made of one piece. The sloping direction faces the drain pipe 3, and the sloping angle can be flexibly designed according to the liquid flow requirements. The lowest point of the bottom is connected to the input end of the drain trough 2. The drain trough 2 is then connected to an external discharge or recycling system through the drain pipe 3. This works in conjunction with the sloping design of the independent guide channel 5 to form a double redirection guide structure. After the washing and pickling processes are completed, the residual washing liquid, pickling liquid, and a small amount of scattered waste in the chamber will flow quickly to the drain trough 2 along the bottom of the sloping cone under the action of gravity, avoiding water accumulation in the chamber and reducing the possibility of bacterial growth in a humid environment. At the same time, it can accelerate the liquid discharge efficiency and shorten the process connection time. During daily cleaning, there is no need to manually wipe the bottom of the chamber 1 repeatedly. Just activate the cleaning spray structure, and the water will flow along the bottom of the sloping cone to the drain pipe 3 to thoroughly drain the sewage. This simplifies the equipment cleaning process, reduces manual maintenance costs, and solves the pain points of the flat bottom of the traditional equipment chamber, which is easy to accumulate water and difficult to clean. This further improves the hygiene and maintenance convenience of the equipment.

[0029] The preferred chamber 1 has a slag removal port 17 at the lowest end of the inclined filter plate 4, and a baffle plate 18 is inserted into the slag removal port 17.

[0030] In this implementation case, the slag removal port 17, located at the lowest end of the inclined filter plate 4 in the silo body 1, is connected to the drainage trough 2. The opening size matches the width of the inclined filter plate 4, facilitating the quick cleaning of solid waste such as fibrous material, impurities, and food scraps intercepted on the inclined filter plate 4. This eliminates the need to disassemble the drainage trough 2, the inclined filter plate 4, and other related components, reducing maintenance difficulty. The liquid baffle 18 inserted at the slag removal port 17 is made of food-grade sealing material and has a tight fit. It can prevent liquid in the drainage trough 2 from overflowing from the slag removal port 17 during normal pretreatment processes, ensuring that all liquid is discharged through the drainage pipe 3. When it is necessary to clean the waste, simply pull out the liquid baffle 18 to quickly clean the waste accumulated on the inclined filter plate 4. After cleaning, reinsert the liquid baffle 18 to resume production without stopping the overall equipment operation, thus not affecting the production progress. At the same time, it avoids secondary pollution caused by the mixing of waste and liquid, ensuring the convenience and hygiene of cleaning operations, improving equipment maintenance efficiency, and solving the problems of cumbersome waste cleaning, the need for machine shutdown and disassembly, and the easy liquid leakage caused by traditional equipment.

[0031] The preferred method is to install the flow guide 5 at an angle toward the drainage trough 2.

[0032] In this implementation, the guide channel 5 is installed at an angle towards the drainage channel 2, with the angle matching the inclined cone structure at the bottom of the chamber 1. This ensures smooth and directional flow of liquid and waste. The surface of the guide channel 5 is polished to reduce the adhesion of liquid and waste within the channel, thus lowering the risk of residue. During the food pretreatment process, the cleaning liquid, marinating liquid, and the fascia and impurities peeled off from the vortex generator vent 10 will flow smoothly along the inclined surface of the guide channel 5 towards the drainage channel 2 at the bottom side of the chamber 1 under the influence of gravity, preventing liquid from accumulating in the chamber 1. The internal diffusion and retention also prevent waste from accumulating in the guide channel 5. At the same time, the inclined design can work with the filtration effect of the inclined filter plate 4 to further improve the solid-liquid separation efficiency, so that waste is quickly intercepted and liquid is quickly discharged, reducing the risk of cross-contamination when processing different batches of food, adapting to the needs of continuous production, and protecting the air holes 6 on the air flotation plate 7 to prevent waste from clogging the air holes 6, ensuring the uniformity of the air cushion layer, ensuring the stability of food suspension, and solving the problems of poor flow guidance, waste accumulation, and easy clogging of air holes in traditional equipment.

[0033] The preferred drain pipe 3 is equipped with a switchable guide branch. The used cleaning liquid or pickling liquid is guided to the designated collection area through the guide branch for recycling. If the pickling liquid is only used once, it will not be recycled.

[0034] In this implementation case, the switchable diversion branch on drain pipe 3 adopts a three-way structure. A manually or automatically controllable switching valve is installed at the branch, allowing for flow direction switching without disassembling the pipeline. The diversion branch connects the cleaning liquid recovery area and the pickling liquid discharge area respectively, adapting to the independent dual-pipeline liquid supply structure in the independent system. During production, the flow can be flexibly switched according to needs: after the cleaning process, the corresponding branch valve is opened, and the used cleaning liquid is diverted through the diversion branch to the designated recovery area, where it can be reused after filtration; after the pickling process, the valve is switched to the discharge branch, and the used pickling liquid is directly diverted to the designated discharge area, achieving single-use and non-recycling, avoiding contamination of the pickling liquid. The diameter of the branch pipeline can also be adjusted according to the production scale to adapt to different needs of small-scale batch production and large-scale continuous production, balancing resource conservation and environmental protection requirements, reducing fresh water consumption, lowering production water costs, and avoiding the environmental pressure caused by direct wastewater discharge. This solves the problems of traditional equipment's single drainage pipeline, inability to achieve classified discharge and recovery of different liquids, and serious resource waste.

[0035] The preferred spray pipe 91 adopts an embedded installation method, which is flush with the inner wall of the chamber 1 to avoid food collision or impurity residue.

[0036] In this implementation, the spray pipe 91 in the cyclone assembly 9 is embedded, flush with the inner wall of the chamber 1, without any protrusions. The surface of the spray pipe 91 is food-grade polished to reduce the adhesion of impurities and liquids, while preventing protruding parts from colliding with the suspended and rotating food, thus preventing meat damage and avoiding food debris remaining in the gap between the spray pipe 91 and the inner wall of the chamber 1. The embedded design allows the nozzle 92 to be flush with the inner wall of the chamber 1, ensuring that the soft flow can be blown out smoothly without turbulence, further enhancing the spiral effect inside the chamber 1. The stability of the full-area flow field, combined with the adjustable angle design of the nozzle 92, allows for more precise control of the direction and speed of the soft flow, ensuring that ingredients of different sizes and types can be evenly enveloped and smoothly driven by the soft flow, thus improving the consistency of pretreatment results. At the same time, it reduces the cleaning dead corners of the equipment. During daily cleaning, only the inner wall of the chamber 1 needs to be wiped, without the need to clean the gaps between the spray pipe 91 and the inner wall. This reduces the difficulty of cleaning and the cost of manual maintenance, and solves the problems of protruding spray pipes, easy collision with food, easy residue of impurities, and difficult cleaning in traditional equipment.

[0037] The preferred air flotation plate 7 is made of food-grade 304 stainless steel, and the air holes 6 are concave micropores with a diameter of 0.6 to 1.0 mm to avoid food residue and blockage.

[0038] In this implementation case, the air flotation plate 7 is made of food-grade 304 stainless steel, which meets the safety standards for food contact materials. It does not release harmful substances, preventing material contamination of food and ensuring food safety. Furthermore, the stainless steel material is corrosion-resistant, easy to clean, and extends the equipment's lifespan. The air holes 6 on the air flotation plate 7 have a concave design, evenly distributed on the surface without any protrusions. This prevents friction between the suspended food and the air holes 6, avoiding damage to the meat's surface. The concave structure also prevents food debris and impurities from entering the air holes 6, preventing blockage and ensuring that the airflow delivered by the air inlet pipe 8 passes evenly through the air holes 6, forming a stable and uniform air cushion layer. This ensures the stability of food suspension and eliminates the need for frequent disassembly of the air flotation plate 7 to clean the air holes 6, reducing maintenance frequency and costs. The air supply volume of the air inlet pipe 8 can be adjusted according to the weight and size of the food to adapt to the thickness of the air cushion layer, accommodating both small and large food items. This solves the problems of traditional equipment air flotation plates not meeting food standards, easily clogged air holes, and unstable food suspension.

[0039] The preferred liquid supply assembly 12 also includes an external liquid circulation filtration module.

[0040] In this embodiment, the liquid circulation filtration module connected to the liquid supply component 12 is connected to the inlet 123 of the annular drain pipe 121 via a pipeline. It is only used for filtering and recovering the cleaning liquid and does not participate in the circulation of the marinating liquid. It works in conjunction with the switchable guide branch on the drain pipe 3 to form a closed-loop cleaning liquid recovery system. The used cleaning liquid is guided to the circulation filtration module through the guide branch of the drain pipe 3. The module is equipped with multiple layers of food-grade filter cartridges, which can effectively remove food debris, impurities and microorganisms from the cleaning liquid. The filtered clean cleaning liquid is then transported back to the annular drain pipe through the pipeline. 121, and then sprayed out through the cleaning liquid spray nozzle 124, realizing the recycling of the cleaning liquid; the filter element can be flexibly replaced according to the turbidity of the cleaning liquid to ensure the cleanliness of the recycled cleaning liquid and avoid contaminating the food. At the same time, it can reduce the consumption of fresh cleaning liquid, reduce the cost of production water, and reduce the environmental pressure caused by direct discharge of wastewater, thus meeting the requirements of environmentally friendly production; the circulating filtration module can also be turned off according to production needs, realizing single use and direct discharge of cleaning liquid, improving production flexibility, and solving the problems of traditional equipment cleaning liquid not being able to be recycled, serious resource waste, and great environmental pressure.
