Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a device for precisely adding color-protecting agents in the sulfur-free color-protecting process of chopped chili peppers. Background Technology

[0002] The sulfur-free color-preserving process for chopped chili peppers refers to a production technology that completely avoids the use of any sulfur-containing chemical additives during the production of chopped chili peppers. Instead, it utilizes physical, biological, and natural chemical methods to maximize the preservation of the chili peppers' natural bright red color and prevent them from turning yellow or brown during processing and storage. The precise color-preserving agent addition device used in this process is an automated metering and addition device specifically designed for food processing. It can inject liquid or dissolved sulfur-free color-preserving agent solution into the stirred chili pepper pieces in a real-time, continuous, and precise manner according to preset process parameters.

[0003] However, existing addition devices typically consist of a storage tank and a conveying unit. The storage tank is usually a single tank. When a new solution needs to be added to the single tank, the peristaltic pump must be stopped to mix the solution and wait for it to dissolve before pumping can be restarted. This causes the production line to stop and affects production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a device for precisely adding color-protecting agents in the sulfur-free color-protecting process of chopped chili peppers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for precisely adding color-protecting agent in the sulfur-free color-protecting process of chopped chili peppers, comprising a support frame and a base. The base is fixedly connected to one side of the bottom end of the support frame. A premixing tank is installed inside the top end of the support frame. A storage and supply tank is installed at the top end of the base. A feeding hopper is connected to the outer side of the top end of the premixing tank, and an inlet pipe is connected to the side of the top end of the premixing tank near the feeding hopper. A conveying pipe is installed at the bottom output end of the premixing tank, and the bottom of the conveying pipe is connected to the storage and supply tank. An outlet pipe is installed on one side of the bottom end of the storage and supply tank, and a peristaltic pump is connected to the output end of the outlet pipe. The bottom end of the peristaltic pump is fixedly connected to the base. A pressure pump is installed on the side of the top end of the base near the peristaltic pump.

[0006] The premixing tank is used to mix the color-protecting agent powder and solvent. The pipes and valves at the bottom of the premixing tank are used to transfer the mother liquor to the storage supply tank. When the liquid level in the storage supply tank drops to a low level, the newly mixed mother liquor from the premixing tank will be transferred to the storage supply tank.

[0007] By operating in parallel with mixing and supply, the premixing tank can prepare the next batch of material while the storage supply tank is supplying the color-protecting agent solution, achieving near-continuous supply and greatly improving production efficiency.

[0008] Preferably, a servo motor is installed at the top center of the premixing tank, and the servo motor is fixedly connected to a rotating column, and a stirring rod is sleeved on the outer wall of the rotating column.

[0009] Preferably, the bottom end of the rotating column is rotatably connected to a limiting seat, and the bottom end of the limiting seat is fixedly connected to the bottom end of the inner wall of the premixing tank, and the stirring rods are evenly distributed.

[0010] The servo motor is started to drive the rotating column to rotate at high speed. At this time, the limit seat guides the rotating column to rotate smoothly. Then, the rotation of the rotating column will drive the stirring rod to rotate at high speed, thereby carrying out thorough and vigorous stirring.

[0011] Preferably, a first reflux pipe is installed in the middle of the outer wall of the premixing tank, and the top of the first reflux pipe is connected to the top of the premixing tank, and the bottom is connected to the bottom of the premixing tank.

[0012] The solution at the bottom of the premixing tank is introduced to the top through the No. 1 reflux pipe.

[0013] Preferably, a second reflux pipe is installed in the middle of the outer wall of the storage supply tank, and the top of the second reflux pipe is connected to the top of the storage supply tank, and the bottom is connected to the bottom of the storage supply tank. A low-speed stirrer is installed inside the storage supply tank.

[0014] By activating the low-speed stirrer inside the storage supply tank, trace amounts of sediment that may form during settling are prevented. At this time, the solution at the bottom of the storage supply tank is directed to the top through the No. 2 reflux pipe.

[0015] Preferably, a cleaning port is embedded on one side of the top of the premixing tank, and a No. 1 cover plate is connected to the top of the cleaning port. Bolts with equal included angles are threaded inside the No. 1 cover plate, and a ladder is welded to the outer side of the top of the support frame.

[0016] Climb up the ladder to the outside of the premixing tank, then turn the bolts to release the fixation of the No. 1 cover plate. After that, open the No. 1 cover plate to expose the cleaning port on the top of the premixing tank. At this time, insert the water gun into the cleaning port to rinse the inside of the premixing tank. The rinsing water flows out of the premixing tank through the drainage channel.

[0017] Preferably, a cleaning trough is embedded on one side of the top of the storage supply tank, and a second cover plate is connected to the top of the cleaning trough. The second cover plate is internally threaded with screws of equal angle, and a drain pipe is installed on the bottom of the storage supply tank near the outlet pipe.

[0018] By turning the screw, the restriction on the second cover is released. Then, the second cover is opened and the water gun is inserted into the storage supply tank for rinsing. The rinsing water is discharged from the storage supply tank through the drain pipe.

[0019] As can be seen from the above, the color-protecting agent precise addition device for the sulfur-free color-protecting process of chopped chili provided by this utility model has the following beneficial effects.

[0020] 1. High-intensity, undisturbed premixing via a mixing tank ensures complete dissolution of the color-protecting agent, preventing clumping and sedimentation. This enables parallel mixing and supply operations. While the storage and supply tank is supplying the color-protecting agent solution, the premixing tank can prepare the next batch, achieving near-continuous supply. This greatly improves production efficiency and ensures that the concentration of the color-protecting agent delivered to every part of the production line is consistent, guaranteeing the accuracy of addition. There is no need to pump while stirring, as the liquid level and stirring state are constantly changing, which can easily lead to concentration fluctuations.

[0021] 2. Open the No. 1 cover and insert the water gun into the cleaning port to rinse the inside of the premixing tank; open the No. 2 cover and insert the water gun into the storage and supply tank to rinse, thus facilitating the cleaning of the inside of the premixing tank and the storage and supply tank by the staff.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-7 This utility model provides a technical solution: a device for precisely adding color-protecting agent in the sulfur-free color-protecting process of chopped chili peppers, including a support frame 1 and a base 2. The base 2 is fixedly connected to one side of the bottom end of the support frame 1. A premixing tank 3 is installed inside the top end of the support frame 1. A storage and supply tank 4 is installed at the top end of the base 2. A feeding hopper 5 is connected to the outer side of the top end of the premixing tank 3. A liquid inlet pipe 6 is connected to the side of the top end of the premixing tank 3 near the feeding hopper 5. A conveying pipe 7 is installed at the bottom output end of the premixing tank 3. The bottom of the conveying pipe 7 is connected to the storage and supply tank 4. An outlet pipe 8 is installed on one side of the bottom end of the storage and supply tank 4. A peristaltic pump 9 is connected to the output end of the outlet pipe 8. The bottom end of the peristaltic pump 9 is fixedly connected to the base 2. A pressure pump 10 is installed on the side of the top end of the base 2 near the peristaltic pump 9.

[0032] The operator adds a measured amount of color-protecting agent powder and solvent into the premixing tank 3 to form a mother liquor with uniform concentration. The mother liquor is then transferred to the storage and supply tank 4 through pipes and valves at the bottom of the premixing tank 3, thus providing a continuous and stable liquid source for the metering pump. The premixing tank 3 performs high-intensity and undisturbed premixing. When the liquid level in the storage and supply tank 4 drops to a low level, a new batch of mixed mother liquor is transferred from the premixing tank 3 to the storage and supply tank 4, forming a semi-continuous production process.

[0033] A servo motor 11 is installed at the top center of the premix tank 3, and a rotating column 12 is fixedly connected to the servo motor 11. A stirring rod 13 is sleeved on the outer wall of the rotating column 12. A limiting seat 14 is rotatably connected to the bottom of the rotating column 12, and the bottom of the limiting seat 14 is fixedly connected to the bottom of the inner wall of the premix tank 3. The stirring rods 13 are evenly distributed. A first reflux pipe 15 is installed in the middle of the outer wall of the premix tank 3, and the top of the first reflux pipe 15 is connected to the top of the premix tank 3, and the bottom is connected to the bottom of the premix tank 3. A second reflux pipe 16 is installed in the middle of the outer wall of the storage and supply tank 4, and the top of the second reflux pipe 16 is connected to the top of the storage and supply tank 4, and the bottom is connected to the bottom of the storage and supply tank 4. A low-speed stirrer is installed inside the storage and supply tank 4.

[0034] In practice, when adding a sulfur-free color-protecting agent solution during the process of making chopped chili peppers, the color-protecting agent powder is first introduced into the premixing tank 3 through the feed hopper 5. Since the output end of the pressure pump 10 is connected to the liquid inlet pipe 6 through the delivery conduit, the pressure pump 10 is then started to guide the water flow to the liquid inlet pipe 6, and then the water flow is introduced into the premixing tank 3 through the liquid inlet pipe 6. After that, the servo motor 11 is started to drive the rotating column 12 to rotate at high speed. At this time, the bottom of the rotating column 12 will rotate along the limit seat 14, and then the limit seat 14 guides the rotating column 12 to rotate smoothly.

[0035] Next, the rotation of the rotating column 12 will drive the stirring rod 13 to rotate at high speed, thereby carrying out thorough and vigorous stirring to ensure that the color-protecting agent powder, such as vitamin C and citric acid, is completely dissolved to form a mother liquor with uniform concentration. This process can fully defoam and ensure complete hydration to avoid clumping. At this time, the solution at the bottom of the premixing tank 3 is introduced to the top through the No. 1 return pipe 15. This process is batch-based and can be unaffected by the production line rhythm, with sufficient time to ensure the mixing quality.

[0036] After thorough mixing, the mother liquor is transferred to the storage supply tank 4 via the delivery pipe 7 and valve. At this time, the storage supply tank 4 acts as a stable buffer and supply source, providing a continuous and stable liquid source for the metering pump. The low-speed stirrer inside the storage supply tank 4 can be activated to prevent trace sedimentation during the settling period. Then, the solution at the bottom of the storage supply tank 4 is guided to the top through the second return pipe 16. After that, the peristaltic pump 9 is activated, so that the solution inside the storage supply tank 4 is discharged through the outlet pipe 8, thereby accurately delivering the color-protecting agent to the chili chopping mixer. The addition ratio of the color-protecting agent is 0.5% of the weight of the chili.

[0037] When the liquid level in storage supply tank 4 drops to a low level, a new batch of mixed mother liquor is transferred from premix tank 3 to storage supply tank 4. At the same time, premix tank 3 can start preparing the next batch of mother liquor, thus forming a semi-continuous production process that will not interrupt the operation of the main production line due to the preparation of color-protecting agents.

[0038] The high-intensity, undisturbed premixing in premixing tank 3 ensures complete dissolution of the color-protecting agent, preventing clumping and sedimentation. This guarantees a consistent concentration of the color-protecting agent delivered to every point on the production line, ensuring accurate addition and eliminating the need for simultaneous stirring and pumping, which can lead to concentration fluctuations due to constant changes in liquid level and stirring conditions. Furthermore, it enables parallel mixing and supply operations. While the storage and supply tank 4 is supplying the color-protecting agent solution, the premixing tank 3 can prepare the next batch, achieving near-continuous supply and significantly improving production efficiency.

[0039] See Figure 1 , Figure 3 , Figure 6 and Figure 7 A cleaning port is embedded on one side of the top of the premix tank 3. The top of the cleaning port is connected to a No. 1 cover plate 17. The No. 1 cover plate 17 is internally threaded with bolts 18 of equal angle. A ladder 19 is welded to the outside of the top of the support frame 1. A cleaning trough is embedded on one side of the top of the storage and supply tank 4. The top of the cleaning trough is connected to a No. 2 cover plate 20. The No. 2 cover plate 20 is internally threaded with screws 21 of equal angle. A drain pipe 22 is installed on the bottom of the storage and supply tank 4 near the outlet pipe 8.

[0040] In practice, the staff first climbs up to the outside of the premixing tank 3 via the ladder 19 on the outer wall of the support frame 1, then rotates and removes the bolt 18 inside the No. 1 cover plate 17, thereby canceling the fixation of the No. 1 cover plate 17. After that, the No. 1 cover plate 17 is opened to expose the cleaning pipe at the top of the premixing tank 3. At this time, the water gun is inserted into the cleaning pipe to rinse the inside of the premixing tank 3. The rinsing water is discharged from the premixing tank 3 through the drainage channel.

[0041] After the staff approaches the base 2, they turn the screw 21 to release the restriction on the second cover 20. Then, they open the second cover 20 and insert the water gun into the storage supply tank 4 to rinse it. The rinsing water flows out of the storage supply tank 4 through the drain pipe 22, which makes it convenient for the staff to clean the premix tank 3 and the storage supply tank 4.

[0042] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
