Description

Technical Field

[0001] This utility model relates to the field of apple juice processing technology, and in particular to a pipeline sterilization device for apple juice processing. Background Technology

[0002] In the apple juice processing industry, the cleanliness of the conveying pipelines, as a crucial carrier for material transport, directly affects the hygiene and safety of the product. Because apple juice is rich in nutrients, residual microorganisms or impurities on the inner walls of the pipelines during transport can easily lead to bacterial growth and product contamination. Therefore, efficient sterilization of the conveying pipelines is a necessary step to ensure the quality of apple juice.

[0003] Currently, the transport pipelines in processing plants require regular sterilization. Traditional sterilization devices suffer from the following problems during use: 1. The mixing of sterilization solution and water relies on a simple stirring structure, which easily leads to concentration stratification, resulting in localized over-concentration or under-concentration of sterilization solution within the pipeline; 2. The sterilization solution relies solely on gravity to flow into the transport pipeline, easily creating flow dead zones in complex structural areas such as bends and valve connections, resulting in incomplete sterilization; 3. The sterilization mechanism and pipelines are mostly fixed connections, making it difficult to clean residual dirt after long-term use, and disassembly and maintenance are time-consuming, failing to meet the high-frequency hygiene cleaning requirements of food processing equipment. Therefore, we propose a pipeline sterilization device for apple juice processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings in the above-mentioned background technology and to propose a pipeline sterilization device for apple juice processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipeline sterilization device for apple juice processing includes a conveying pipeline and multiple control valves fixedly installed on the conveying pipeline, wherein a sterilization mechanism is provided on the outer wall of the conveying pipeline;

[0007] The sterilization mechanism includes a vertical pipe head fixedly installed on the outer wall of the conveying pipe. A connecting pipe is fixedly installed on the top of the vertical pipe head, and a sterilization tank is fixedly installed on the top of the connecting pipe. The sterilization tank has a sterilization liquid inlet and a water inlet on its top. A servo motor is fixedly installed on the top of the sterilization tank. A rotating shaft extending into the sterilization tank is fixedly installed on the output shaft of the servo motor. Multiple stirring plates are fixedly installed on the outer wall of the rotating shaft. Multiple liquid outlet pipes are fixedly installed at the bottom of the conveying pipe. Liquid outlet valves are fixedly sleeved on the outer walls of the connecting pipe and the liquid outlet pipes.

[0008] Preferably, the vertical pipe head and the connecting pipe are detachably connected by multiple bolts.

[0009] Preferably, a sterilization inlet pipe and a water inlet pipe are fixedly installed on the top of the sterilization tank, the sterilization inlet pipe and the sterilization liquid inlet are connected, and the water inlet pipe and the water inlet are connected.

[0010] Preferably, multiple stirring plates in the same layer are arranged in a ring array on the outer wall of the rotating shaft, and the sterilization tank and the rotating shaft are coaxially arranged.

[0011] Preferably, the end of the rotating shaft is provided with a liquid-turning mechanism, the liquid-turning mechanism including a rotating shaft fixedly installed at the end of the rotating shaft, and a spiral fan blade fixedly sleeved on the outer wall of the rotating shaft.

[0012] Preferably, the rotating shaft and the rotating shaft are coaxially arranged.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A pipeline sterilization device for apple juice processing includes a conveying pipeline 1 and multiple control valves 2 fixedly installed on the conveying pipeline 1. A sterilization mechanism is provided on the outer wall of the conveying pipeline 1. The sterilization mechanism includes a vertical pipe head 3 fixedly installed on the outer wall of the conveying pipeline 1. A connecting pipe 4 is fixedly installed on the top of the vertical pipe head 3. A sterilization tank 5 is fixedly installed on the top of the connecting pipe 4. The sterilization tank 5 has a sterilization liquid inlet 6 and a water inlet 7 on its top. A servo motor 8 is fixedly installed on the top of the sterilization tank 5. A rotating shaft 9 extending into the sterilization tank 5 is fixedly installed on the output shaft of the servo motor 8. Multiple stirring plates 10 are fixedly installed on the outer wall of the rotating shaft 9. Multiple liquid outlet pipes 11 are fixedly installed at the bottom of the conveying pipeline 1. Liquid outlet valves 12 are fixedly sleeved on the outer walls of the connecting pipe 4 and the liquid outlet pipes 11.

[0022] To further explain, by setting an independent sterilization mechanism on the outside of the conveying pipe 1, sterilization can be carried out simultaneously during the apple juice conveying process, avoiding the cumbersome process of traditional offline sterilization and improving processing efficiency. The servo motor 8 in the sterilization tank 5 drives the rotating shaft 9 and the stirring plate 10 to stir, which can evenly mix the sterilization liquid and water, ensuring a stable concentration of the sterilization solution and improving the sterilization effect. The liquid outlet pipe 11 is distributed at the bottom of the conveying pipe 1. With the liquid outlet valve 12, the sterilization liquid can flow evenly into the pipe and fully contact the apple juice to achieve comprehensive sterilization.

[0023] like Figure 1 As shown, the vertical pipe head 3 and the connecting pipe 4 are detachably connected by multiple bolts 13.

[0024] To further explain, the internal components of the sterilization mechanism (such as the stirring plate 10 and the sterilization tank 5) are easy to disassemble, clean, or maintain, which avoids the growth of bacteria in residual liquid, ensures the hygiene of the equipment, and the detachable design reduces the difficulty of maintenance, shortens downtime, and improves the maintainability and service life of the equipment.

[0025] like Figure 1 As shown, the sterilization tank 5 is fixedly installed with a sterilization inlet pipe 14 and a water inlet pipe 15. The sterilization inlet pipe 14 and the sterilization liquid inlet 6 are connected, and the water inlet pipe 15 and the water inlet 7 are connected.

[0026] To further explain, this design allows for the independent addition of the sterilizing solution and water, and the ratio of the two can be flexibly adjusted according to the sterilization requirements of the apple juice, improving the adaptability of the sterilization solution. The pipeline design ensures the stability of the liquid flow and avoids the problem of uneven concentration that may be caused by manual mixing.

[0027] like Figure 3 As shown, multiple stirring plates 10 in the same layer are arranged in a ring array on the outer wall of the rotating shaft 9, and the sterilization tank 5 and the rotating shaft 9 are arranged coaxially.

[0028] To further explain, the ring-shaped array of stirring plates 10 can cover the entire cross-section of the sterilization tank 5. Together with the coaxial rotating shaft 9, they form a uniform stirring vortex, ensuring that the sterilization liquid and water are quickly and thoroughly mixed. The coaxial arrangement reduces eccentric vibration during stirring, lowers equipment operating noise, and improves stability.

[0029] like Figure 1 and Figure 3 As shown, a liquid-turning mechanism is provided at the end of the rotating shaft 9. The liquid-turning mechanism includes a rotating shaft 16 fixedly installed at the end of the rotating shaft 9, and a spiral fan blade 17 is fixedly sleeved on the outer wall of the rotating shaft 16.

[0030] To further explain, when the spiral fan blade 17 rotates inside the connecting pipe 4, it can push the mixed disinfectant liquid downwards, enhance the liquid conveying power, avoid uneven flow rate or sedimentation problems caused by gravity, and the liquid turning action further stirs the liquid, preventing the disinfectant liquid from settling inside the connecting pipe 4 and ensuring that the concentration of the disinfectant liquid flowing into the conveying pipe 1 is consistent.

[0031] like Figure 1 and Figure 3 As shown, the rotating shaft 9 and the rotating shaft 16 are coaxially arranged.

[0032] To further explain, this design ensures the synchronous rotation of the spiral fan blade 17 and the rotating shaft 9, avoiding mechanical wear or uneven liquid disturbance caused by eccentric rotation, and improving the reliability and efficiency of the liquid-turning mechanism.

[0033] like Figure 1 As shown, the spiral fan blade 17 is located inside the connecting pipe 4.

[0034] To further explain, this design directly acts on the liquid inside the connecting pipe 4, shortens the power transmission path, improves the liquid pushing efficiency, ensures that the disinfectant flows into the delivery pipe 1 in a timely and stable manner, and limits the position of the spiral fan blade 17, which can precisely control the flow rate and direction of the liquid in the connecting pipe 4, and avoids backflow or stagnation of the disinfectant.

[0035] The functional principle of this utility model can be explained through the following operation methods:

[0036] I. Pipeline sterilization operation steps (including enhanced sterilization of dead corners)

[0037] 1. Preparation and mixing of disinfectant solution

[0038] Operation: Same as the original procedure, inject a measured amount of sterilization solution and clean water through sterilization inlet pipe 14 and water inlet pipe 15.

[0039] Key upgrade: Start the servo motor 8 to rotate forward, driving the stirring plate 10 and the spiral fan blade 17 to rotate forward synchronously, so that the sterilization solution is mixed quickly and the stirring time is extended to 1-2 minutes to ensure uniform concentration.

[0040] 2. Pipeline connection and sterilization solution injection

[0041] Forward rotation injection: Open the outlet valve 12 of the connecting pipe 4, keep the servo motor 8 rotating forward, and the spiral fan blade 17 pushes the sterilizing liquid through the connecting pipe 4, the vertical pipe head 3 and the outlet pipe 11 into the delivery pipe 1. Adjust the flow rate of apple juice to 5-8L / min to form a flow in the same direction as the sterilizing liquid (enhancing the mixing effect).

[0042] Injection volume control: By observing the pipeline level gauge or timing (assuming pipeline volume V, injection time t = V / flow rate), when the sterilizing solution fills 2 / 3 of the pipeline volume, close the feed valve and stop the apple juice delivery.

[0043] 3. Enhanced sterilization in hard-to-reach areas

[0044] Reverse tumbling: Switch servo motor 8 to reverse, and spiral fan blade 17 rotates in the opposite direction, causing the sterilizing liquid to form a vortex in the delivery pipe 1, so that the sterilizing liquid circulates and tumbles between sterilization tank 5 → connecting pipe 4 → delivery pipe 1 → delivery pipe 1 → connecting pipe 4 → sterilization tank 5 (circulation time 3-5 minutes).

[0045] Dead corner treatment: Focusing on areas prone to dead corners such as pipe bends and valve connections, the disinfectant is made to fully contact the inner wall through eddy current impact and pressure changes (back pressure generated by reverse reversal).

[0046] 4. Resume conveying and emptying.

[0047] Resume forward rotation: After completing the dead zone treatment, switch the servo motor to rotate forward 8 times, reopen the feed valve, and resume apple juice delivery (flow rate 10-15L / min), and discharge the enhanced sterilized liquid into the collection container.

[0048] II. Equipment Cleaning and Maintenance Procedures (including Reverse Cleaning)

[0049] 1. Initial flushing of the pipeline

[0050] Forward rinsing: Inject clean water into sterilization tank 5, start servo motor 8 to rotate forward, maintain a flow rate of 15-20L / min, rinse the pipeline for 5 minutes, and remove most of the residual sterilization liquid and impurities.

[0051] 2. Reverse circulation cleaning (a new key step)

[0052] Close the outlet valve 12: Close the outlet valve 12 on the outside of the connecting pipe 4, leaving only the return valve at the end of the pipe open.

[0053] Reverse vortex cleaning: Switch the servo motor 8 to reverse, and the spiral fan blade 17 forms an upward suction force in the connecting pipe 4, so that the clean water forms a high-speed circulation between the sterilization tank 5 → connecting pipe 4 → sterilization tank 5 for 3-5 minutes, using the vortex to peel off the deposits on the tank wall and the inner wall of the pipe.

[0054] Alternating forward and reverse rotation: The motor direction is switched every 1 minute (1 minute forward → 1 minute reverse). The cleaning effect is enhanced by changing the direction of water flow, and the back of the stirring plate 10 and the root of the spiral fan blade 17 are the areas where dirt easily accumulates.

[0055] 3. Disassembly and deep cleaning of components

[0056] Same as above: Disassemble the vertical pipe head 3, flush the connecting pipe 4 and the liquid outlet pipe 11 with a high-pressure water gun, and manually clean the inner wall of the sterilization tank 5.
