Description

Technical Field

[0001] This invention relates to the field of food additive equipment technology, and in particular to a portable device for precise calibration of the weight and ingredients of medical formula foods. Background Technology

[0002] With increasing public focus on health and nutrition, the demand for medical formula foods is growing. However, traditional methods of preparing medical formula foods are inaccurate and cumbersome due to the precise ingredient combinations and weight calibration required. To address this issue, we propose a portable device for precise weight and ingredient calibration of medical formula foods, aiming to provide users with a simple and accurate solution for ingredient calibration and weight measurement. Users can prepare medical formula foods according to their individual needs, ensuring nutritional balance and safety, which helps improve health and enhance patient recovery.

[0003] Existing food quantitative addition equipment, such as the Chinese utility model application with application number 202322110063.X, entitled "An Automatic Quantitative Addition Device for Food Additives," includes a support plate with several storage tanks mounted on it. A through hole is formed in the middle of the support plate, connecting to a weighing tank. Each storage tank is equipped with a feeding device, the output ends of which extend through the through hole into the weighing tank. A quantitative device is installed inside the weighing tank. This device ensures that additional additives are added within the time it takes to close the discharge port. By using a feeding device with a fixed feeding amount per unit time, the accuracy of quantitative addition is improved.

[0004] The existing technology has the following drawbacks: In the above-mentioned feeding device, the material-lifting device draws raw materials from the storage tank through a rotating shaft and blades. The raw materials at the bottom of the storage tank cannot be fully drawn, and the operator needs to perform manual operation to ensure that all raw materials are fully utilized, which increases the complexity and workload of the operation and reduces the efficiency of batching. The inability to effectively draw raw materials at the bottom of the storage tank also leads to waste of raw materials and increases the cost of batching. At the same time, it may also cause raw material residues to accumulate inside the equipment, increasing the difficulty of cleaning and maintaining the equipment. Therefore, there is room for improvement. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a portable medical formula food weight and ingredient precision calibration device to solve the technical problem in existing food addition equipment where raw materials cannot be fully utilized, leading to the accumulation of raw materials inside the equipment and thus waste.

[0006] This invention is achieved through the following technical solution:

[0007] A portable device for precise calibration of the weight and ingredients of medical formula foods includes a mixing tank, a first feeding mechanism, a second feeding mechanism, a stirring assembly, and a discharge port. Both the first and second feeding mechanisms are located at the top of the mixing tank. The stirring assembly is located inside the mixing tank for mixing the food. The discharge port is located at the bottom of the mixing tank. The first feeding mechanism is used for feeding liquid ingredients and includes a first feeding hopper, a first feeding trough, and a first tilting assembly. The first feeding trough is located below the first feeding hopper, and the first tilting assembly is used to tilt the first feeding trough. The second feeding mechanism is used for feeding solid ingredients and includes a second feeding hopper, a second feeding trough, and a second tilting assembly. The second feeding trough is located below the first feeding hopper, and the second tilting assembly is used to tilt the second feeding trough. Weighing sensors are installed in both the first and second feeding troughs.

[0009] Preferably, a second guide valve is provided between the second feeding hopper and the second feeding trough, a solid collection box is provided on the mixing box, a second collection pipe is provided between the solid collection box and the second feeding trough, and a pressure pump is provided on the second collection pipe.

[0010] Preferably, the inner wall of the mixing tank is further provided with an air jet assembly, which includes air holes, air pipes and an air pump. The air hole array is distributed on the inner wall of the mixing tank. The air holes are connected to the air pump through the air pipes. The air jet direction of the air holes is towards the horizontal tangential direction of the stirring assembly.

[0011] Preferably, the inner bottom surface of the mixing box is provided with a material gathering plate, the material gathering plate is inclined, the lower inclined part of the material gathering plate guides the mixed food to the discharge port, and a vibration motor is provided at the bottom of the material gathering plate.

[0012] Preferably, a coarse guide pipe and a fine guide pipe are provided between the second feeding hopper and the second feeding trough. The second guide valve includes a first discharge valve and a second discharge valve. The first discharge valve is provided on the coarse guide pipe, and the second discharge valve is provided on the fine guide pipe.

[0013] Preferably, a scraper assembly is provided on the upper end face of the material-gathering plate. The scraper assembly includes a connecting shaft and a rotating plate. The rotating plate is rotatably mounted on the connecting shaft and rotates along the material-gathering plate.

[0014] Preferably, both the first and second flipping components include a cylinder, a connecting arm, and a rotating shaft. The first and second feeding troughs are rotatably mounted on the connecting arm via the rotating shaft. The connecting arm is mounted on the telescopic end of the cylinder. A limiting groove is provided on the top of the mixing box. The upper ends of the first and second feeding troughs are engaged with the limiting groove.

[0015] Preferably, the water tank is located at the lower part of the aggregate plate, the air pipe is connected to the water tank, and a water pump is also installed on the air pipe.

[0016] Preferably, the stirring assembly includes a motor, a stirring shaft, and stirring paddles. The stirring paddles are staggered on the stirring shaft. The motor drives the stirring shaft to rotate. There are two sets of stirring shafts, located at the lower part of the first feeding trough and the second feeding trough, respectively.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. By setting up a first feeding mechanism and a second feeding mechanism, and adopting a separate channel design, the supply paths for liquid and solid ingredients are separated. Weighing sensors are installed in the first and second feeding troughs to weigh the liquid and solid ingredients respectively. During the feeding process, only the set amount of ingredients is used. The first and second flipping mechanisms flip the first and second feeding troughs to pour all the weighed ingredients into the mixing tank, reducing the waste of raw materials during the feeding process. The separate channel design also facilitates cleaning and maintenance of the equipment. Separate weighing and feeding reduce the complexity of the device, improve the portability of the feeding device, simplify the operation process, and facilitate the rapid preparation of medical food.

[0019] 2. The first feed valve controls the amount of liquid ingredients dispensed. The liquid collection tank and water tank store residual liquid ingredients and cleaning water, respectively, enabling cleaning and rinsing of the first feeding trough, reducing the impact of residual ingredients, and ensuring the quality and accuracy of subsequent ingredient dispensing. The second feed valve controls the amount of solid ingredients dispensed. Water stains in the solid collection tank ensure timely cleaning of the second feeding trough, avoiding cross-contamination between different ingredients and improving the efficiency of medical food preparation. By drawing residual solid ingredients from the second feeding trough into the solid collection pipe, raw material waste is minimized, saving costs.

[0020] 3. By setting up coarse and fine feed pipes, coarse and secondary precision calibration of solid ingredients is achieved. The material is introduced into the coarse feed pipe from the second feeding hopper, and is initially fed through the first discharge valve for coarse precision calibration. After the initial calibration through the coarse feed pipe, the material enters the fine feed pipe, and is further adjusted and calibrated through the second discharge valve for secondary precision calibration. After the secondary calibration through the fine feed pipe, the ingredients are finally fed into the second feeding trough, completing the entire calibration process and improving the feeding accuracy of medical formula foods.

[0040] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0042] Please see Figures 1-9 A portable device for precise calibration of the weight and ingredients of medical formula foods includes a mixing tank 1, a first feeding mechanism 2, a second feeding mechanism 3, a stirring assembly 4, and a discharge port. The first feeding mechanism 2 and the second feeding mechanism 3 are both located at the upper part of the mixing tank 1. The stirring assembly 4 is located inside the mixing tank 1 for mixing the food. The discharge port is located at the lower part of the mixing tank 1. The first feeding mechanism 2 is used for feeding liquid ingredients and includes a first feeding hopper 21 and a first feeding trough 22. The first tilting component 23 is used to tilt the first feeding trough 22. The first feeding trough 22 is located at the lower part of the first feeding hopper 21. The first tilting component 23 is used to tilt the first feeding trough 22. The second feeding mechanism 3 is used to feed solid ingredients. The second feeding mechanism 3 includes a second feeding hopper 31, a second feeding trough 32 and a second tilting component 33. The second feeding trough 32 is located at the lower part of the first feeding hopper 21. The second tilting component 33 is used to tilt the second feeding trough 32. Weighing sensors 5 are provided in both the first feeding trough 22 and the second feeding trough 32.

[0043] The operating principle of the precision calibration device of the present invention is as follows:

[0044] Operators feed liquid and solid ingredients separately through the first feeding mechanism 2 and the second feeding mechanism 3. Liquid ingredients enter the first feeding trough 22 via the first feeding hopper 21. Weighing sensors 5 monitor the weight of the added ingredients in real time and feed this information back to the system. When the added ingredients reach a preset value, the operator is prompted to stop feeding. At this point, the first tilting component 23 tilts the first feeding trough 22, allowing the liquid ingredients in the first feeding trough 22 to enter the mixing tank 1, completing the feeding operation of the first feeding mechanism 2. Solid ingredients enter the mixing tank 1 via the second feeding hopper 31. Inside the second feeding trough 32, the weighing sensor 5 monitors the weight of the added ingredients in real time and feeds the weight information back to the system. When the added ingredients reach the preset value, the operator is prompted not to continue feeding. At this time, the second flipping component 33 flips the second feeding trough 32, allowing the solid ingredients in the second feeding trough 32 to enter the mixing box 1, completing the feeding operation of the second feeding mechanism 3. After both liquid and solid ingredients are added, the stirring component 4 starts to work, stirring and mixing the ingredients to ensure that the ingredients are fully and evenly mixed. After the mixing is completed, the final food formula is output through the discharge port.

[0045] Since the weighing sensor 5 is installed in the first feeding trough 22 and the second feeding trough 32, only the set amount of ingredients needs to be used during the ingredient preparation process. The first and second flipping mechanisms pour all the weighed ingredients into the mixing tank 1, ensuring full utilization of the ingredients and reducing waste in the precise proportioning process. By setting the weighing sensor 5 and the flipping mechanism, it is ensured that only the set amount of ingredients is used in each ingredient preparation process, avoiding overuse or waste. The weighing sensor 5 can accurately monitor the weight of the ingredients, and together with the flipping mechanism, pour all the weighed ingredients into the mixing tank 1, ensuring that each ingredient is accurately added to the food formula in the required proportion. Although different ingredients may have different shapes, densities, and other characteristics, the consistency and stability of each ingredient preparation can be guaranteed through the cooperation of the weighing sensor 5 and the flipping mechanism.

[0046] Simultaneously, separate weighing and feeding through different channels enables precise control of solid and liquid ingredients. Weighing sensors 5, installed in each individual feeding channel, accurately monitor the amount of each ingredient, ensuring the accuracy and consistency of the formula and improving the quality and stability of food processing. The separate channel design separates the supply paths for liquid and solid ingredients, facilitating equipment cleaning and maintenance, avoiding the difficulty of cleaning when different types of ingredients are mixed together, and helping to maintain the hygiene and cleanliness of the equipment. Separate weighing and feeding allows for simultaneous dispensing of solid and liquid ingredients, improving the efficiency of medical food preparation. Separate weighing and feeding also reduces the complexity of the device, improves its portability, simplifies the operation process, and facilitates rapid medical food preparation.

[0047] Please see Figure 2 , Figure 3 and Figure 5 To reduce the impact of residual ingredients and ensure the quality and accuracy of subsequent ingredient preparation, in one embodiment, a first guide valve 24 is provided between the first feeding hopper 21 and the first feeding trough 22, a liquid collection tank 6 and a water tank 7 are provided on the mixing tank 1, a first collection pipe 25 is provided between the liquid collection tank 6 and the first feeding trough 22, a water spray pipe 26 is provided between the water tank 7 and the first feeding trough 22, and a pressure pump is provided between the first collection pipe 25 and the water spray pipe 26.

[0048] The first feed valve 24 is located between the first feeding hopper 21 and the first feeding trough 22, controlling the amount of liquid ingredients dispensed. The weight of the liquid ingredients in the first feeding trough 22 is monitored by a weighing sensor 5. The first feed valve 24 is communicatively connected to the weighing sensor 5, and its switch is adjusted as needed to prevent over-dispensing and ensure the accuracy and stability of the dispensing process. The liquid collection tank 6 and the water tank 7 are used to store the liquid ingredients and water for cleaning, respectively. When cleaning the first feeding trough 22, a pressure pump sprays water from the water tank 7 into the first feeding trough 22 through a spray pipe 26 to rinse away any remaining ingredients. The rinsed liquid and residual ingredients are introduced into the liquid collection tank 6 through the first collection pipe 25, completing the cleaning of the first feeding tank 22. The pressure pump increases the water pressure, ensuring that the water spray pipe 26 effectively rinses the residual ingredients in the first feeding tank 22 and introduces the rinsing liquid into the first feeding tank 22, ensuring the cleanliness of the first feeding tank 22. The above settings work together to effectively control the amount of liquid ingredients fed, clean and rinse the first feeding tank 22, reduce the impact of residual ingredients, and ensure the quality and accuracy of subsequent ingredients.

[0049] Please see Figure 2 and Figure 4To avoid cross-contamination between different ingredients and ensure the purity of raw materials during the preparation of medical formula foods, in one embodiment, a second feed valve 34 is provided between the second feeding hopper 31 and the second feeding trough 32. A solid collection box 8 is provided on the mixing tank 1, and a second collection pipe 35 is provided between the solid collection box 8 and the second feeding trough 32. A pressure pump is provided on the second collection pipe 35. The function of the second feed valve 34 between the second feeding trough 32 and the second feeding hopper 31 is to control the amount of solid ingredients fed. The valve is connected to the weighing sensor 5 and can be adjusted as needed to ensure that the required solid ingredients enter the second feeding trough 32 in the correct proportion, avoiding overfeeding or underfeeding. After the flipping mechanism flips the second feeding trough 32 to feed the ingredients, the second collecting pipe 35 and the pressure pump adsorb the solid raw materials remaining in the second feeding trough 32 into the solid collecting pipe, thus cleaning the second feeding trough 32. By thoroughly cleaning the second feeding trough 32, the mixing of different batches of ingredients and contamination by residual impurities can be avoided, ensuring that the quality of the prepared medical formula food meets the standards. Timely cleaning of the second feeding trough 32 can avoid cross-contamination between different ingredients, ensuring the purity of raw materials in the preparation process of medical formula food. Keeping the second feeding trough 32 clean can reduce the cleaning time when changing batches of ingredients, saving medical formula food preparation time and improving the preparation efficiency of medical formula food. By drawing the solid ingredients remaining in the second feeding trough 32 into the solid collecting pipe, raw material waste can be minimized and costs saved.

[0050] Please see Figure 2 and Figure 7 To better disperse and mix the ingredients, and effectively prevent them from clumping or sticking to the inner wall of the mixing tank 1, in one embodiment, an air jet assembly 9 is also provided on the inner wall of the mixing tank 1. The air jet assembly 9 includes air holes 91, air pipes, and an air pump. The air holes 91 are arrayed on the inner wall of the mixing tank 1, and are connected to the air pump via air pipes. The air jet direction of the air holes 91 is towards the horizontal tangential direction of the stirring assembly 4. By spraying airflow into the mixing tank 1, the air jet assembly 9 can make the raw materials in the mixing tank 1 more thoroughly mixed. The movement and action of the airflow help to better mix the raw materials, ensuring uniform mixing quality. The air jet assembly 9 can accelerate the mixing speed of the raw materials in the mixing tank 1, making the mixing process faster and more efficient. The stirring action of the airflow can improve mixing efficiency and save batching time; the action of the airflow can better disperse and mix the ingredients, thereby improving the uniformity of the mixture. This helps ensure that all components are evenly distributed in the mixture, avoiding localized uneven concentrations. The jet assembly 9 effectively prevents ingredients from clumping or sticking to the inner wall of the mixing chamber 1. The airflow separates the raw materials, preventing clumping and ensuring a smooth mixing process.

[0051] Please see Figure 2 and Figure 5 To ensure the mixed food is evenly guided to the outlet and to reduce residual substances in the mixing tank 1, in one embodiment, a material-gathering plate 10 is provided on the inner bottom surface of the mixing tank 1. The material-gathering plate 10 is inclined, and the lower inclined part of the material-gathering plate 10 guides the mixed food to the outlet. A vibration motor 11 is provided at the bottom of the material-gathering plate 10. The inclined material-gathering plate 10 at the bottom of the mixing tank 1, mainly through the angle of inclination and the vibration motor 11 at the bottom, evenly guides the mixed food to the outlet. When the mixing chamber 1 is stirring and mixing, the mixed food will gradually flow down the inclined surface of the material gathering plate 10. The vibration force generated by the vibration motor 11 can help the medical formula food move better on the material gathering plate 10, thereby promoting the uniform mixing of the mixture. Through the design of a reasonable tilt angle and the action of vibration force, the mixed food can flow smoothly to the discharge port, reducing the time that the food stays in the chamber, effectively shortening the medical food preparation cycle and improving the efficiency of medical food preparation. The tilt setting of the material gathering plate 10 and the operation of the vibration motor 11 help to control the time and speed of the mixing process. Once the food mixture reaches a certain consistency, the design of the material-gathering plate 10 and the action of the vibration motor 11 promptly guide the mixed food to the discharge port, preventing over-mixing of ingredients and ensuring the quality of the medical formula food. The material-gathering plate 10 and the vibration motor 11 effectively guide the mixed food to the discharge port, reducing residual substances in the mixing tank 1 and lowering cleaning and maintenance costs. The inclined design of the material-gathering plate 10 and the action of the vibration motor 11 promote the flow of the mixed food, ensuring that the mixture can fully contact and stir during the mixing process, improving mixing efficiency and ensuring mixing quality.

[0052] Please see Figure 2 and Figure 4To achieve multiple calibration processes and make the material flow more accurate and stable, in one embodiment, a coarse guide pipe 36 and a fine guide pipe 37 are provided between the second feeding hopper 31 and the second feeding trough 32. The second guide valve 34 includes a first discharge valve 341 and a second discharge valve 342. The first discharge valve 341 is located on the coarse guide pipe 36, and the second discharge valve 342 is located on the fine guide pipe 37. The coarse guide pipe 36 is used for coarse precision calibration. The material is guided through the coarse guide pipe 36 to the discharge port into the second feeding trough 32, realizing the initial calibration of the material and improving the overall accuracy of the material. The fine guide pipe 37 is used for secondary precision calibration. After the initial calibration through the coarse guide pipe 36, the value measured by the weighing sensor 5 is compared with the preset value, and the difference is fed back to the second discharge valve 342. The material will be guided into the fine guide pipe 37 to continue flowing into the second feeding trough 32. The finer feed tube 37 is more precisely designed, allowing for further adjustment and calibration of the feed flow rate and precision, ensuring product quality and accuracy. The first discharge valve 341 is located on the coarse feed tube 36 and is primarily used to control the flow rate and speed of material entering the coarse feed tube 36 from the second feed hopper 31. By opening and closing the first discharge valve 341, the initial material discharge can be controlled, achieving coarse precision calibration. The second discharge valve 342 is located on the fine feed tube 37 and is used to control the flow rate and speed of material entering the fine feed tube 37 from the coarse feed tube 36. The design of the second discharge valve 342 is more refined, allowing for more accurate flow adjustment and secondary precision calibration. The material is introduced from the second feeding hopper 31 into the coarse guide pipe 36, and initially discharged under the control of the first discharge valve 341 for coarse precision calibration. After the initial calibration in the coarse guide pipe 36, the material enters the fine guide pipe 37, where it is further adjusted and calibrated under the control of the second discharge valve 342 for secondary precision calibration. After the secondary calibration in the fine guide pipe 37, the material is finally introduced into the second feeding trough 32, completing the entire calibration process.

[0053] Please see Figure 2 and Figure 6To reduce stratification between ingredients and ensure thorough mixing of different ingredients, in one embodiment, a scraper assembly 12 is provided on the upper surface of the material-gathering plate 10. The scraper assembly 12 includes a connecting shaft 121 and a rotating plate 122. The rotating plate 122 is rotatably mounted on the connecting shaft 121 and rotates along the material-gathering plate 10. The scraper assembly 12 is used to clean the ingredients adhering to the material-gathering plate 10. In the preparation of medical formula foods, some ingredients are highly adhesive and easily remain on the surface of the material-gathering plate 10. If not cleaned in time, the ingredients will accumulate on the material-gathering plate 10, affecting mixing efficiency and food quality. The rotation of the rotating plate 122 can effectively clean the surface of the material-gathering plate 10, pushing the adhering ingredients to one side or scraping them off, ensuring the cleanliness and purity of the ingredient mixing; through the action of the scraper assembly 12, the accumulation of mixed ingredients on the material-gathering plate 10 can be effectively prevented. The rotation of the rotating plate 122 pushes the ingredients to one side, preventing excessive accumulation or piling up and maintaining a uniform distribution, thus reducing waste. The movement of the scraper assembly 12 helps improve the mixing uniformity of the ingredients. The rotation of the rotating plate 122 ensures even distribution of the ingredients on the material collection plate 10, reducing stratification and ensuring thorough mixing of different ingredients. This improves the quality and consistency of medical food preparation, guaranteeing that the product meets the designed ingredient ratios and quality standards. The scraper assembly 12 also improves the efficiency of the medical food preparation line. By continuously cleaning the ingredients, preventing accumulation, and improving mixing uniformity, the scraper assembly 12 ensures stable flow of ingredients during the medical food preparation process, improving food mixing efficiency.

[0054] Please see Figure 8 and Figure 9To prevent ingredients from falling directly into the mixing tank 1 and to ensure the accuracy of the weighing sensor 5, in one embodiment, both the first flipping assembly 23 and the second flipping assembly 33 include a cylinder 13, a connecting arm 14, and a rotating shaft 15. The first feeding trough 22 and the second feeding trough 32 are rotatably mounted on the connecting arm 14 via the rotating shaft 15. The connecting arm 14 is mounted on the telescopic end of the cylinder 13. A limit groove is provided on the top of the mixing tank 1, and the upper ends of the first feeding trough 22 and the second feeding trough 32 are engaged with the limit groove. During the feeding process, cylinder 13 is compressed, causing the first feeding trough 22 and the second feeding trough 32 to be engaged in the limiting groove. At this time, all the material passing through the first feeding hopper 21 and the second feeding hopper 31 falls into the first feeding trough 22 and the second feeding trough 32 respectively. After the weighing sensor 5 detects that the reading is stable, cylinder 13 is stretched, causing the first feeding trough 22 and the second feeding trough 32 to move downward and disengage from the limiting groove. The motor drives the rotating shaft 15 to rotate the first feeding trough 22 and the second feeding trough 32, thus turning them over and introducing the material in the first feeding trough 22 and the second feeding trough 32 into the mixing box 1 for subsequent mixing operations. After the rotation is completed, the motor drives the rotating shaft 15 to rotate the first feeding trough 22 and the second feeding trough 32 again. Cylinder 13 is compressed, causing the first feeding trough 22 and the second feeding trough 32 to be engaged in the limiting groove, allowing feeding operations to be performed on the first feeding mechanism 2 and the second feeding mechanism 3 again. By engaging the upper ends of the first feeding trough 22 and the second feeding trough 32 with the limiting groove, the sealing of the two troughs during the feeding process can be guaranteed, effectively preventing the ingredients from falling directly into the mixing box 1, ensuring that the ingredients flow effectively into the troughs, ensuring the accuracy of the weighing sensor 5, ensuring the effective weighing of the ingredients, and helping to improve the accuracy of the ingredients.

[0055] Please see Figure 8In one embodiment, to effectively remove residual materials and dirt from the mixing tank 1 and maintain its cleanliness, a water tank 7 is located below the material-aggregating plate 10, and an air pipe is connected to the water tank 7. A water pump is also installed on the air pipe. Air holes 91 in the jet assembly 9 are arranged on the inner wall of the mixing tank 1 and connected to the air pump via an air pipe. The jet direction is towards the horizontal tangent of the stirring assembly 4. When the air pump operates, the airflow is injected into the mixing tank 1 through the air pipe and air holes 91, creating airflow dynamics that rapidly stir, mix, and evenly distribute the raw materials within the mixing tank 1. This design effectively shortens the mixing time and improves mixing efficiency, thereby accelerating the preparation process of medical food. The water tank 7 is located below the material-aggregating plate 10, and the air pipe is connected to the water tank 7 and equipped with a water pump. After mixing, water can be supplied to the air pipe using the water pump and sprayed out through the air holes 91 to clean the inner wall of the mixing tank 1. This water spray cleaning function effectively removes residual materials and dirt from the mixing tank 1, keeping it clean and hygienic, preventing cross-contamination, and improving the cleanliness of the mixing space. The jet assembly 9 accelerates the mixing process, and the water spray cleaning function improves mixing efficiency, shortens the time spent on mixing and cleaning, and reduces waiting time for cleaning during mixing. Simultaneously, it maintains the cleanliness of the equipment and the uniformity of the raw material mixing, helping to save on maintenance and cleaning costs. The water tank 7 is located below the material collection plate 10, achieving full utilization of the space in the mixing tank 1 and improving the compactness of the mixing tank 1's spatial structure.

[0056] Please see Figure 2 and Figure 7 To ensure thorough mixing and agitation of the ingredients, and to guarantee the quality and uniformity of the mixture, in one embodiment, the mixing assembly 4 includes a motor, a mixing shaft 41, and mixing paddles 42. The mixing paddles 42 are staggered on the mixing shaft 41. The motor drives the mixing shaft 41 to rotate. Two sets of mixing shafts 41 are provided, located below the first feeding trough 22 and the second feeding trough 32, respectively. The first feeding trough 22 and the second feeding trough 32 are used to introduce the ingredients into the mixing tank 1. By providing two sets of mixing shafts 41, each located below a different feeding trough, thorough mixing and agitation of the ingredients can be ensured. When the mixing paddles 42 rotate, the ingredients are effectively stirred, pushed, and mixed, resulting in uniform mixing of different ingredients and ensuring the quality and uniformity of the mixture. By positioning the mixing shafts 41 in different feeding troughs, thorough mixing of different types of ingredients can be ensured, reducing instances of uneven mixing. The staggered distribution design of the mixing paddles 42 allows the ingredients to cover a wider area during the mixing process, ensuring uniformity and consistency of the mixture.
