Description

Technical Field

[0001] This utility model relates to the field of food testing technology, and in particular to a liquid food stirring device for food testing. Background Technology

[0002] Food testing is a crucial technical means to ensure food safety and protect consumer health, and it is widely used in all stages of food production, distribution, and regulation. Liquid foods, as an important target in food testing, mainly include liquid or semi-liquid products such as dairy products, beverages, and condiments. Their complex composition and high fluidity necessitate strict requirements for the standardization and consistency of sample pretreatment during testing. Stirring, as a key step in the pretreatment of liquid foods for testing, directly affects the homogeneity of the sample and the accuracy of the test results.

[0003] Specifically, the existing utility model patent CN221148259U, "A Liquid Food Stirring Device for Food Testing," discloses a structure including a base, a lifting frame, an electric cylinder, a lifting seat, a stirring assembly, a defoaming assembly, a detector, and a stirring tank, and is equipped with a moving assembly for moving the liquid food. This device achieves stirring by driving the stirring assembly up and down with the electric cylinder, and reduces foam generation through the defoaming assembly, thus avoiding excessive foam affecting work efficiency. Simultaneously, the moving assembly assists in the flow of the liquid food, preventing spillage and environmental contamination during transfer and improving the accuracy of test results.

[0004] However, in practical applications, this device still has significant shortcomings. The stirring component has a single function, leading to insufficient stirring and uneven mixing, especially when dealing with high-viscosity or particulate liquid samples, where the stirring effect is even worse, severely affecting the representativeness and repeatability of the test data. Furthermore, the power system's response during stirring is limited, making it difficult to adapt to diverse stirring needs and restricting its applicability. More seriously, these problems directly lead to reduced sample pretreatment efficiency and increased operational complexity in food testing, making it difficult to meet the demands of high-precision, high-volume testing tasks. Uneven stirring can increase detection errors, thereby affecting the scientific rigor and authority of food safety assessments, and even leading to potential quality risks and regulatory loopholes. Therefore, to address the many shortcomings of existing technologies, we urgently need an innovative liquid food stirring device for food testing to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a liquid food stirring device for food testing, which solves the problem that the stirring components in the prior art have a single function, resulting in insufficient stirring and uneven mixing. In particular, when dealing with liquid samples with high viscosity or containing particulate matter, the stirring effect is even worse, which seriously affects the representativeness and repeatability of the test data.

[0006] To achieve the above objectives, this utility model provides a liquid food stirring device for food testing, including a frame and a rotating rod rotatably connected to the inner side of the frame, with fixed sleeves fitted on both ends of the rotating rod.

[0007] Several agitating rods are fixedly connected between two fixed sleeves, and an adsorption frame is sleeved on the rotating rod. A top frame is fixedly connected to the top of the frame, and a spray plate is slidably connected to the bottom of the top frame. A pump body is fixedly connected to one side of the outer wall of the frame by bolts. The outlet of the pump body is connected to one side of the spray plate. A feeding pipe is fixedly connected to one side of the outer wall of the frame, and a spiral rod is rotatably connected to the inside of the feeding pipe. The top of the feeding pipe is connected to the inlet of the pump body, and the bottom of the feeding pipe is connected to the lower part of the frame. One end of the spiral rod is connected to one end of the rotating rod by a belt winding.

[0008] Both the screw rod and the rotating rod are fitted with pulleys, and the two pulleys are connected by a belt winding around each other.

[0009] The lower side of the frame is equipped with a valve body, one end of the rotating rod is rotatably connected to the inner wall of the frame, and the other end of the rotating rod passes through the side wall of the frame through a bearing sleeve.

[0010] The pump body's outlet is connected to one side of the spray plate via a hose, and the pump body's inlet is connected to the bottom inner side of the frame via a bottom pipe.

[0011] One end of the screw rod is rotatably connected to the inner wall of the feeding pipe via a rotating shaft, and the other end of the screw rod passes through the side wall of the feeding pipe via a bearing sleeve.

[0012] An electric slider is fixedly connected to the top side of the spray plate, and the electric slider is slidably connected to the top of the top frame via a slide rail.

[0013] This invention relates to a liquid food stirring device for food testing. It utilizes a pump to drive liquid circulation, and the liquid's own kinetic energy to rotate a screw rod. A belt then drives a rotating rod and a stirring rod to achieve the stirring action. This overcomes the limitations of traditional electric stirring methods, achieving an energy-saving stirring mode without the need for an external motor. It also solves the problem that existing stirring devices, due to their single power system response, cannot adapt to the diverse stirring needs of liquid foods. Furthermore, the stirring rod is rigidly connected to the rotating rod via a fixed sleeve, creating multi-point disturbance in the liquid during rotation, enhancing the stirring intensity and coverage. This makes it particularly suitable for high-viscosity or particulate-containing liquids. For liquid foods, this design effectively improves the uniformity and stability of sample mixing, thereby ensuring the accuracy and repeatability of test results. Furthermore, the sliding connection between the spray plate and the top frame automatically adjusts the spray height according to the liquid flow rate, avoiding foam accumulation caused by liquid splashing or excessive local impact. Combined with the particle adsorption function of the adsorption frame, this further reduces residual bubbles and impurities during the stirring process, improving the overall quality of sample pretreatment. In addition, the vertical connection between the feeding pipe and the frame forms a complete liquid circulation path, which not only improves stirring efficiency but also facilitates subsequent cleaning and maintenance, reducing equipment operating costs and operational complexity.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A liquid food stirring device for food testing includes a frame 1, and a rotating rod 15 is rotatably connected to the inner side of the frame 1, with a fixing sleeve 16 sleeved on both ends of the rotating rod 15.

[0024] Several stirring rods 13 are fixedly connected between two fixed sleeves 16, and an adsorption frame 17 is sleeved on the rotating rod 15. A top frame 2 is fixedly connected to the top of the frame 1, and a spray plate 5 is slidably connected to the bottom of the top frame 2. A pump body 7 is fixedly connected to one side of the outer wall of the frame 1 by bolts. The outlet of the pump body 7 is connected to one side of the spray plate 5. A feeding pipe 8 is fixedly connected to one side of the outer wall of the frame 1, and a spiral rod 9 is rotatably connected to the inner side of the feeding pipe 8. The top side of the feeding pipe 8 is connected to the inlet of the pump body 7, and the bottom of the feeding pipe 8 is connected to the lower part of the frame 1. One end of the spiral rod 9 is connected to one end of the rotating rod 15 by a belt 11.

[0025] In actual use, the liquid food to be tested is first injected into the frame 1. Then, the pump 7 is started. The pump 7 is connected to the top of the feeding pipe 8 through its inlet end, drawing the liquid from the frame 1 into the feeding pipe 8 and pressurizing it to the spray plate 5. The spray plate 5 is slidably connected to the bottom of the top frame 2 and can be adjusted in height according to changes in liquid level to ensure that the liquid is evenly sprayed back into the frame 1. During this cycle, the liquid flows through the feeding pipe 8, driving the screw rod 9 to rotate. One end of the screw rod 9 is connected to one end of the rotating rod 15 via a belt 11. Driven by the screw rod 9, the rotating rod 15 rotates... The rotating rod 15 rotates accordingly; fixed sleeves 16 are provided at both ends of the rotating rod 15, and multiple stirring rods 13 are fixedly connected between the two fixed sleeves 16. As the rotating rod 15 rotates, the stirring rods 13 fully stir the liquid food inside the frame 1, enhancing the mixing uniformity; at the same time, an adsorption frame 17 is also sleeved on the rotating rod 15. The adsorption frame 17 can adsorb and filter suspended particles or impurities in the liquid, further improving the sample processing quality; the whole process forms a self-circulating stirring system driven by liquid flow, which can achieve efficient and continuous stirring operation without additional power source.

[0026] Furthermore, pulleys 10 are fitted onto one end of the screw rod 9 and one end of the rotating rod 15, and the two pulleys 10 are connected by a belt 11. When the liquid flows through the feeding pipe 8, it drives the screw rod 9 to rotate, thereby causing the pulley 10, which is mounted on the same axis, to rotate synchronously. The power is then transmitted to the other pulley 10 at the end of the rotating rod 15 through the belt 11, thus driving the entire stirring mechanism to operate in conjunction. This structure achieves a power transmission method that can complete the stirring function without an external motor. It achieves the effect of using the liquid's own flow to drive the stirring device, improving the energy efficiency and automation of the equipment, while simplifying the operation process and enhancing the system's adaptability.

[0027] Furthermore, a valve body 12 is installed on the lower side of the frame 1. One end of the rotating rod 15 is rotatably connected to the inner wall of the frame 1, and the other end of the rotating rod 15 passes through the side wall of the frame 1 through a bearing sleeve. The valve body 12 can be used to control the discharge or sampling of liquid food, improving the flexibility of sample processing. The rotating rod 15 passes through the side wall of the frame 1 through a bearing sleeve, which ensures good sealing and stability during rotation, preventing liquid leakage and ensuring smooth transmission. This structural design effectively improves the overall ease of operation and maintenance of the equipment. It enhances the stability of the stirring system and facilitates sampling control, making it suitable for flexible operation needs under different testing tasks.

[0028] Furthermore, the outlet of the pump body 7 is connected to one side of the spray plate 5 via a hose 6, and the inlet of the pump body 7 is connected to the inner bottom of the frame 1 via a bottom pipe 14. The pump body 7 draws liquid from the bottom of the frame 1 and delivers it to the spray plate 5 through the hose 6, forming a complete liquid circulation loop. Due to the flexible connection characteristics of the hose 6, it can adapt to the displacement changes during the sliding adjustment process of the spray plate 5, ensuring the continuity of liquid supply. This structure improves the flexibility and reliability of the liquid delivery path, achieving the functional effects of enhancing the uniformity of stirring, ensuring circulation efficiency, and adapting to the height adjustment of the spray plate 5, ensuring a stable and efficient stirring process.

[0029] Furthermore, one end of the screw rod 9 is rotatably connected to the inner wall of the feeding pipe 8 via a rotating shaft, and the other end of the screw rod 9 passes through the side wall of the feeding pipe 8 via a bearing sleeve. The screw rod 9 can rotate stably inside the feeding pipe 8 without deviation. When the liquid flows through, it can efficiently drive the screw rod 9 to rotate, thereby achieving effective extraction of power. The use of the bearing sleeve also reduces frictional resistance and extends the service life of the screw rod 9. This structure enhances the stability and durability of the power conversion system inside the feeding pipe 8, achieving the effect of improving the utilization rate of liquid kinetic energy and ensuring transmission efficiency, providing a continuous and stable power source for subsequent stirring actions.

[0030] Furthermore, an electric slider 3 is fixedly connected to the top side of the spray plate 5, and the electric slider 3 is slidably connected to the top of the top frame 2 via a slide rail 4. During the stirring process, the electric slider 3 slides along the slide rail 4, driving the spray plate 5 to automatically adjust its height position to match the current liquid level, ensuring uniform liquid spraying, reducing foam generation, and preventing liquid splashing. This structure realizes the intelligent adjustment function of the spray plate 5 height, achieving the effects of optimizing the liquid reflux path, improving stirring uniformity, and reducing bubble residue, further enhancing the quality and consistency of sample pretreatment, and meeting the requirements of high-precision detection.

[0031] In summary:

[0032] First, the liquid food to be tested is injected into the frame 1, and the pump 7 is started. The pump 7 is connected to the top of the feeding pipe 8 through its inlet end, and the liquid is drawn from the bottom of the frame 1 through the bottom pipe 14. Then, the liquid is pressurized and delivered to the spray plate 5. The spray plate 5 has a height adjustment function through the electric slider 3 and the slide rail 4, which can automatically adjust the spray position according to the liquid level change, ensuring that the liquid is sprayed evenly and flows back into the frame 1 to form a circulating flow system. During this process, when the liquid flows through the feeding pipe 8, it drives the screw rod 9 to rotate. One end of the screw rod 9 is rotatably connected to the inner wall of the feeding pipe 8 through a rotating shaft, and the other end passes through the side wall of the feeding pipe 8 through a bearing sleeve to ensure stable rotation and reduce friction loss. When the screw rod 9 rotates, it drives the pulley 10 installed on the same axis to rotate synchronously, and then the power is transmitted to the end of the rotating rod 15 through the belt 11. Another pulley 10 drives the entire stirring mechanism to operate in conjunction. Fixed sleeves 16 are provided at both ends of the rotating rod 15, and multiple stirring rods 13 are fixedly connected between the two fixed sleeves 16. When the rotating rod 15 rotates, it thoroughly stirs the liquid food, enhancing the uniformity of mixing. Simultaneously, an adsorption frame 17 is fitted onto the rotating rod 15 to adsorb suspended particles or impurities in the liquid, improving sample processing quality. Furthermore, one end of the rotating rod 15 passes through the side wall of the frame 1 via a bearing sleeve, and the other end is rotatably connected to the inner wall of the frame 1, ensuring its rotational stability and sealing. A valve body 12 is provided on one side of the lower part of the frame 1, which can be used to control liquid discharge or sampling, improving operational flexibility. The entire process forms a self-circulating stirring system driven by the liquid's own flow, achieving efficient and continuous stirring operation without the need for an additional power source.The pump body 7 drives the liquid circulation, and the liquid kinetic energy drives the screw rod 9 to rotate. The pulley 10 and belt 11 then drive the rotating rod 15 and stirring rod 13 to achieve stirring. This overcomes the limitations of traditional electric stirring methods, achieving an energy-saving stirring mode without external motor direct drive. It solves the problem that existing stirring devices, due to their single power system response, cannot adapt to the diverse stirring needs of liquid foods. Secondly, the stirring rod 13 is rigidly connected to the rotating rod 15 through the fixed sleeve 16. During rotation, it can create multi-point disturbance in the liquid, enhancing the stirring intensity and coverage. This is particularly suitable for high-viscosity or particulate-containing liquid foods, effectively improving the uniformity and stability of sample mixing, thus ensuring the accuracy and repeatability of test results. Thirdly, the spray plate 5 achieves height adjustment through the electric slider 3 and slide rail 4, intelligently adjusting the spray position according to changes in the liquid level, avoiding liquid splashing or excessive local impact causing foam accumulation. The particle adsorption function of the adsorption frame 17 further reduces residual bubbles and impurities during the stirring process, improving the overall quality of sample pretreatment. Furthermore, the vertical connection between the feed pipe 8 and the frame 1 forms a complete liquid circulation path, which not only improves stirring efficiency but also facilitates subsequent cleaning and maintenance, reducing equipment operating costs and complexity. The pump body 7 and the spray plate 5 are flexibly connected by a flexible hose 6, adapting to displacement changes during the sliding process of the spray plate 5 and ensuring continuous liquid supply and system operational stability. The screw rod 9 achieves stable rotation through a rotating shaft and bearing sleeve, extending its service life and improving transmission efficiency. The valve body 12 provides convenience for sample collection or discharge, enhancing the equipment's operational flexibility and practicality. This comprehensively improves the efficiency, accuracy, and practicality of liquid food testing pretreatment, meeting the demands of modern food testing for automated, standardized, and high-precision testing processes, and possesses significant promotional value and application prospects.
