Description

Technical Field

[0001] This utility model relates to the field of micropeptide preparation production technology, specifically a pH detection device for nutrient solution in micropeptide preparation production. Background Technology

[0002] Micropeptide preparations, a type of small-molecule active peptide mixture synthesized by microbial fermentation, are widely used in food additives, feed fortifiers, and pharmaceutical intermediates due to their easy absorption, strong bioactivity, and high safety. In the fermentation production process of micropeptide preparations, the pH value of the nutrient solution is one of the core process parameters. Real-time, accurate, and stable monitoring of the nutrient solution pH value is a crucial step in ensuring the production efficiency and product quality of micropeptide preparations.

[0003] Currently used nutrient solution pH detection devices are mostly single-probe designs. The probe surface is prone to adhering to micropeptide residues and viscous metabolites. If not cleaned promptly, this can hinder ion exchange between the electrode and the nutrient solution, easily leading to cross-contamination and reducing detection accuracy. However, stopping the device to disassemble and clean the probe interrupts real-time pH monitoring, affecting detection efficiency. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a pH detection device for nutrient solution in the production of micropeptide preparations. This invention solves the problem mentioned in the background art that most commonly used pH detection devices for nutrient solutions are designed with a single probe. The surface of the detection probe is prone to adhering micropeptide residues and viscous metabolites. If not cleaned in time, these residues will hinder ion exchange between the electrode and the nutrient solution, easily causing cross-contamination and reducing detection accuracy.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pH detection device for nutrient solution in the production of micropeptide preparations, comprising a horizontal plate, with cleaning frames at both ends of the horizontal plate, an upper spray pipe and a lower spray pipe on the inner side of the cleaning frame, and the two upper spray pipes and two lower spray pipes in the left and right cleaning frames respectively connected to their respective delivery pipes, and a pH detection sensor fixedly connected to both ends of the horizontal plate, with the detection probe of the pH detection sensor located below the horizontal plate.

[0006] In this technical solution, two alternating pH detection sensors are installed on the surface of the horizontal plate, so that while one is detecting, the other is being rinsed and cleaned. This allows for alternating operation of the probes without stopping the machine, avoiding the problem of interrupted monitoring due to machine stoppage for cleaning in single-probe designs. It also prevents cross-contamination between the cleaning and detection processes, ensuring the continuity of detection and the accuracy of data.

[0007] Preferably, a top plate is provided directly above the horizontal plate, and an electric slide rail is installed at the bottom of the top plate. An electric push rod is fixedly connected to the slider surface of the electric slide rail, and the bottom of the electric push rod is fixedly connected to the horizontal plate.

[0008] Preferably, the inner walls of both the upper and lower spray pipes are provided with a plurality of spray pipes, the upper spray pipe being used to spray clean water and the lower spray pipe being used to spray neutralizing cleaning solution.

[0009] Preferably, the cleaning frame has two side frames at the edge of the side wall opening, one of which has a number of electric heating tubes fixedly connected to its inner side.

[0010] Preferably, the cleaning frame has a drain outlet at the lower end of its side wall, and the drain outlet communicates with the interior of the cleaning frame.

[0011] Preferably, a fan is installed on the outer surface of the side frame outside the electric heating tube, and the fan's exhaust direction is towards the electric heating tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model installs two alternating pH detection sensors on the surface of the horizontal plate, so that while one is detecting, the other is being rinsed and cleaned. This allows for alternating operation of the probes without stopping the machine, avoiding the problem of interrupted monitoring due to machine stoppage for cleaning in single-probe designs. It also prevents cross-contamination between the cleaning and detection processes, ensuring the continuity of detection and the accuracy of data.

[0013] 2. This utility model cleans the detection probe by setting a cleaning frame. The lower spray pipe sprays a neutralizing cleaning agent to neutralize the micro-peptide preparation, and the upper spray pipe sprays clean water for rinsing. Combined with the hot air flow formed by the fan and electric heating tube, it can quickly dry the moisture on the probe surface, ensuring the detection sensitivity of the probe after cleaning and extending the service life of the probe.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0017] A pH detection device for nutrient solution in the production of micropeptide preparations, see [link to device]. Figures 1 to 4 The device includes a horizontal plate 4, with cleaning frames 6 at both ends. An upper spray pipe 11 and a lower spray pipe 12 are located inside the cleaning frames 6. A pH sensor 5 is fixedly connected to both ends of the horizontal plate 4, with the detection probe 501 of the pH sensor 5 located below the horizontal plate 4. The device uses the horizontal plate 4 as its core supporting structure. The pH sensors 5 at both ends can operate alternately, ensuring the continuity of pH monitoring of the nutrient solution. When one detection probe 501 is inserted into the nutrient solution for pH detection, the other detection probe 501 can enter the corresponding cleaning frame 6 for cleaning. The upper spray pipe 11 and lower spray pipe 12 within the cleaning frame 6 form a layered cleaning structure, targeting residual micropeptides and viscous metabolites on the surface of the detection probe 501. This ensures that the probe can be quickly used for the next round of testing after cleaning, reducing the obstruction of electrode ion exchange by residual substances, minimizing the risk of cross-contamination, and improving the accuracy of the detection data.

[0018] Specifically, a top plate 1 is located directly above the horizontal plate 4, and an electric slide rail 2 is installed at the bottom of the top plate 1. An electric push rod 3 is fixedly connected to the slider surface of the electric slide rail 2, and the bottom of the electric push rod 3 is fixedly connected to the horizontal plate 4. The top plate 1 is fixed at a suitable position above the conveyor belt. The electric slide rail 2 can drive the electric push rod 3 to achieve horizontal reciprocating movement, thereby driving the horizontal plate 4 and the pH detection sensors 5 at both ends to adjust horizontally synchronously. The electric push rod 3 can control the vertical height of the horizontal plate 4 through its extension and retraction action, realizing the switching of the detection probe 501 extending into or out of the nutrient solution and entering or leaving the cleaning frame 6. It should be noted that a conveyor belt is located below the horizontal plate 4, and containers of micro-peptide preparations pass through the conveyor belt in sequence for testing.

[0019] Furthermore, such as Figure 3As shown, the two upper spray pipes 11 and two lower spray pipes 12 in the left and right cleaning frames 6 are respectively connected to their respective conveying pipes 10, which are connected to containers storing clean water and neutralizing cleaning solution, and are driven to draw water by their respective liquid pumps; the inner walls of the upper spray pipes 11 and the lower spray pipes 12 are provided with several spray pipes, the upper spray pipes 11 are used to spray clean water, and the lower spray pipes 12 are used to spray neutralizing cleaning solution. The lower end of the side wall of the cleaning frame 6 is provided with an outlet 13, which is connected to the interior of the cleaning frame 6.

[0020] In the above technical solution, the delivery pipe 10 draws the corresponding liquids from the clean water container and the neutralizing cleaning solution container respectively through a liquid pump, and delivers the clean water to the upper spray pipe 11 and the neutralizing cleaning solution to the lower spray pipe 12; the upper spray pipe 11 and the lower spray pipe 12 can form a multi-directional, full-coverage spraying effect through several spray holes on their inner walls; the lower spray pipe 12 first sprays out the neutralizing cleaning solution, which reacts with the micropeptides remaining on the probe surface to neutralize and decompose the viscous substances; then the upper spray pipe 11 sprays out clean water to rinse away the remaining neutralizing solution and impurities; the waste liquid after cleaning is discharged through the outlet 13 at the lower end of the side wall of the cleaning frame 6 to prevent the waste liquid from accumulating in the cleaning frame 6.

[0021] It is worth noting that, such as Figure 3 As shown, the cleaning frame 6 has two side frames 7 at the edge of the side wall opening. Several electric heating tubes 8 are fixedly connected to the inner side of one of the side frames 7. A fan 9 is installed on the outer surface of the side frame 7 outside the electric heating tubes 8, and the exhaust direction of the fan 9 is towards the electric heating tubes 8. After the detection probe 501 completes the spray cleaning, the electric heating tubes 8 are energized to generate heat. At the same time, the fan 9 starts and exhausts air towards the electric heating tubes 8. The air is heated by the electric heating tubes 8 to form hot air. The hot air enters the cleaning frame 6 through the side wall opening and quickly dries the damp detection probe 501. The two side frames 7 can guide the hot air to ensure that the hot air is concentrated on the probe surface.

[0022] In addition, all components designed in this utility model are general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
