Description

Technical Field

[0001] This invention specifically relates to the field of persimmon pulping technology, and more specifically to a highly efficient persimmon pulp preparation device and method with color-protecting properties. Background Technology

[0002] During the planting, harvesting, and transportation of persimmons, the skin is prone to adhering to microorganisms such as bacteria, mold, and yeast from the soil. If the persimmons are not washed before pulping, these microorganisms will enter the pulp and multiply rapidly, leading to spoilage and causing gastrointestinal diseases after consumption. In addition, pesticides and fungicides may be used in persimmon cultivation, leaving residues in the waxy layer of the skin or in the crevices of the fruit. Direct pulping will allow these pesticides to enter the pulp, and long-term ingestion can harm health. Furthermore, during transportation, the persimmon skin may absorb dust, heavy metal particles, and packaging material residues. These contaminants cannot be completely removed by subsequent pulping and sterilization.

[0003] Chinese Patent Application No. 202120813463.5 discloses a persimmon brush cleaning machine, including a cabinet, a brush mechanism, and a spray nozzle. One end of the cabinet is provided with a feed inlet. The brush mechanism is located inside the cabinet and below the feed inlet. A spray bracket is installed on the top of the cabinet, and the spray nozzle is installed on the spray bracket. A discharge port is opened on the side wall of the cabinet opposite to the feed inlet. A water collection tank is provided on the cabinet at the lower end of the brush mechanism. A water outlet pipe is provided in the middle and lower part of the water collection tank. A pump body is connected to the water outlet pipe, and the water outlet pipe is connected to the spray nozzle.

[0004] The persimmon brush cleaning machine in the aforementioned patent, when cleaning persimmons with a spray nozzle and brush mechanism, can only remove visible impurities from the surface of the persimmons if the spray nozzle sprays water. It is difficult to remove invisible stains such as oily stains caused by field dust, pesticide residues, or heavy metals. If the spray nozzle sprays a fruit and vegetable cleaning agent, a large amount of cleaning agent and cleaning agent foam will remain on the surface of the persimmons after they are discharged from the outlet, requiring a second cleaning with water. Therefore, the persimmon brush cleaning machine described above cannot guarantee the cleaning effect or the efficiency of the persimmon cleaning work. Summary of the Invention

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Please see Figure 1-17 In a specific embodiment of the present invention, a high-efficiency color-protecting persimmon pulp preparation device is introduced. The device includes a bubble washing machine 10, with a front washing assembly 1 and a rear washing assembly 2 symmetrically arranged at the discharge end of the bubble washing machine 10, both of which are connected to a frame assembly 3. A cleaning agent spraying assembly 8 is located at the bottom of one end of the frame assembly 3 near the front washing assembly 1, and a clean water spraying assembly 9 is located at the bottom of the other end of the frame assembly 3. The top of the front washing assembly 1 is connected to a front transmission assembly 7, and the top of the rear washing assembly 2 is connected to a rear transmission assembly 6. Both the rear transmission assembly 6 and the front transmission assembly 7 are connected to a drive assembly 5.

[0053] As a further explanation of the above embodiments, the bubble washing machine 10 is a special washing machine for cleaning fruits and vegetables, and is widely used in the market. As it is prior art, its specific structure and working principle will not be described in detail here.

[0054] Furthermore, the pre-washing assembly 1 and the post-washing assembly 2 have the same structure; the pre-washing assembly 1 includes a plurality of brush rollers 11 evenly distributed in a ring, and each of the plurality of brush rollers 11 is coaxially fixedly connected to a drive shaft 12; one end of each of the plurality of drive shafts 12 is coaxially fixedly connected to a driven bevel gear 18, and the top of each of the plurality of driven bevel gears 18 meshes with a driving bevel gear 17; the top of the driving bevel gear 17 is coaxially fixedly connected to an inner shaft 19; the driving bevel gear 17 and the plurality of driven bevel gears 18 are all located inside a rotating shell 13, and a cylindrical shell 14 is integrally provided in the middle of the top of the rotating shell 13, the top of which is fixedly connected to an inner cylinder 15, and a flange 16 is integrally provided in the top of the inner cylinder 15; the ends of the plurality of drive shafts 12 near the driven bevel gears 18 are rotatably connected to the rotating shell 13 through bearings 110; a space is provided between the cylindrical shell 14 and the inner cylinder 15 to accommodate the inner shaft 19 and allow the inner shaft 19 to rotate normally.

[0055] Furthermore, the rear transmission assembly 6 and the front transmission assembly 7 have the same structure; the rear transmission assembly 6 includes a redirecting bevel gear 63, the top and bottom of which mesh with the upper bevel gear 62 and the lower bevel gear 61 respectively; the upper bevel gear 62 is coaxially fixedly connected to a connecting shaft 64, the bottom of which is coaxially fixedly connected to the top of the inner shaft 19; the bottom of the lower bevel gear 61 is fixedly connected to a flange 2 65, which is fixedly connected to flange 1 16.

[0056] The drive assembly 5 includes a drive sprocket 52, a driven sprocket 1 53, and a driven sprocket 2 54 arranged in a triangular pattern. The drive sprocket 52, driven sprocket 1 53, and driven sprocket 2 54 are all located inside the chain 55 and are all engaged with the chain 55. The drive sprocket 52 is coaxially and fixedly connected to the output shaft of the reducer unit 51. The driven sprocket 1 53 is coaxially and fixedly connected to the top of the connecting shaft 64 of the rear transmission assembly 6. The driven sprocket 2 54 is coaxially and fixedly connected to the top of the connecting shaft 64 of the front transmission assembly 7.

[0057] As a further explanation of the above embodiments, a tension gear can be provided between the driving sprocket 52, driven sprocket 1 53 and driven sprocket 2 54. When the tension gear is provided, the tension gear is located outside the chain 55 and meshes with the chain 55. By increasing the tension of the chain 55, it is ensured that the driving sprocket 52, driven sprocket 1 53 and driven sprocket 2 54 are always meshed with the chain 55.

[0058] The profile frame 41 is fixedly connected to a vertical frame 43 at one top end, and a mounting plate 44 is fixedly connected to the end of the vertical frame 43 away from the profile frame 41. The reducer unit 51 is fixedly connected to the mounting plate 44. The bottom ends of both ends of the profile frame 41 are fixedly connected to the bubble cleaning machine 10.

[0059] By adopting the above technical solution, persimmons can smoothly enter the subsequent cleaning process after the visible impurities are initially cleaned by the bubble cleaning machine. The drive component 5 drives the rear transmission component 6 and the front transmission component 7 to operate, which in turn drives the front washing component 1 and the rear washing component 2 to work. When the persimmons pass under the cleaning agent spraying component 8, the fruit and vegetable cleaning agent is evenly sprayed onto the surface of the persimmons. Under the drive of the drive component 5, the multiple brush rollers 11 of the front washing component 1 not only rotate rapidly on their own, but also rotate around the rotating shell 13 as the center. This compound motion mode allows the brush rollers 11 to fully and deeply contact the surface of the persimmons, which can efficiently remove invisible stains and oily stains from the surface of the persimmons.

[0060] Next, the persimmon continues to move to the area below the water spray component 9, where a large amount of water is sprayed onto the persimmon. The brush roller 11 of the rear washing component 2 also rotates in a combination of rotation and revolution, quickly removing the residual cleaning agent and cleaning agent foam from the surface of the persimmon. Throughout the entire cleaning process, the various components work closely together, and the multi-stage cleaning method not only ensures the cleaning effect of the persimmon but also greatly improves the efficiency of the cleaning work.

[0061] The simultaneous rotation and revolution of multiple brush rollers 11 in the front washing assembly 1 and the rear washing assembly 2 are achieved in the following way: when the connecting shaft 64 rotates, it drives the inner shaft 19 and the rotating active bevel gear 17. The active bevel gear 17 drives multiple driven bevel gears 18 to rotate, which in turn drives multiple brush rollers 11 to rotate. When the connecting shaft 64 rotates, it drives the upper bevel gear 62 to rotate synchronously. The upper bevel gear 62 drives the lower bevel gear 61 to rotate through the redirecting bevel gear 63. The lower bevel gear 61 drives the cylinder shell 14 to rotate, thereby causing the rotating shell 13 to rotate. The rotating shell 13 can drive multiple brush rollers 11 to rotate, realizing the revolution of multiple brush rollers 11.

[0062] Please see the appendix Figure 12-17 In this embodiment, the lower bevel gear 61 has a through hole in the middle for the connecting shaft 64 to pass through. The connecting shaft 64 passes through flange 2 65 and flange 1 16 and extends into the inner cylinder 15 and is fixedly connected to the inner shaft 19.

[0063] The upper bevel gear 62 is rotatably connected to the upper support seat 67, and the lower bevel gear 61 is rotatably connected to the lower support seat 66; the ends of the upper support seat 67 and the lower support seat 66 away from the lower bevel gear 61 are both fixedly connected to the second connecting plate 68; the redirecting bevel gear 63 is coaxially fixedly connected to a support shaft 69, and the end of the support shaft 69 away from the redirecting bevel gear 63 is rotatably connected to the second connecting plate 68.

[0064] Furthermore, a support assembly 4 is provided between the rear transmission assembly 6 and the front transmission assembly 7. The support assembly 4 includes a profile frame 41, and connecting plates 42 are fixedly connected to both sides of the profile frame 41. The connecting plates 68 of the rear transmission assembly 6 and the connecting plates 68 of the front transmission assembly 7 are respectively fixedly connected to the two connecting plates 42.

[0065] By adopting the above technical solution, the bracket assembly 4 provides a stable support structure for the rear transmission assembly 6 and the front transmission assembly 7, ensuring the stability of the transmission assembly during operation.

[0066] Meanwhile, the structural design of the connecting shaft 64 passing through flange 2 65 and flange 1 16 and extending into the inner cylinder 15 to be fixedly connected to the inner shaft 19 enables the rear transmission assembly 6 and the front transmission assembly 7 to effectively transmit power to the front washing assembly 1 and the rear washing assembly 2, ensuring that the brush roller 11 can stably rotate and revolve, further improving the effect and efficiency of persimmon cleaning.

[0067] Please see the appendix Figure 6-7In this embodiment, the frame assembly 3 includes a frame 31, with support seats 34 provided in the middle of the inner sides of both ends of the frame 31. The cylindrical shell 14 of the front washing assembly 1 and the cylindrical shell 14 of the rear washing assembly 2 are respectively rotatably connected to the two support seats 34 on the same axis. Connecting frames 33 are fixedly connected to both sides of the two support seats 34, and all four connecting frames 33 are fixedly connected to the frame 31. Support frames 32 are fixedly connected to both sides of the frame 31, and the bottom of the four support frames 32 are fixedly connected to the bubble cleaning machine 10.

[0068] The cleaning agent spraying assembly 8 includes a cleaning agent delivery pipe 81, and the cleaning agent delivery pipe 81 is fixedly connected to the bottom of the frame 31 through multiple connectors 83; multiple nozzles 82 are evenly fixedly connected to one end of the cleaning agent delivery pipe 81 near the frame 31, and the other end of the cleaning agent delivery pipe 81 away from the frame 31 is connected to a fruit and vegetable cleaning agent supply device.

[0069] The clean water spray assembly 9 includes a front clean water delivery pipe 91 and a rear clean water delivery pipe 94. The front clean water delivery pipe 91 is fixedly connected to the bottom middle of the frame 31 through multiple connectors 93, and the rear clean water delivery pipe 94 is fixedly connected to the bottom end of the frame 31 through multiple connectors 93.

[0070] Furthermore, both the pre-water supply pipe 91 and the post-water supply pipe 94 are fixedly connected to and communicate with the main pipe 95; multiple nozzles 92 are evenly fixedly connected to the pre-water supply pipe 91 and the post-water supply pipe 94; the end of the main pipe 95 near the frame 31 is fixedly connected to one of the support frames 32 through a connector 96, and the end of the main pipe 95 away from the frame 31 is connected to the water supply device.

[0071] By adopting the above technical solutions, the frame assembly 3 provides a stable support and installation structure for the front washing assembly 1 and the rear washing assembly 2, enabling the two washing assemblies to operate stably in the appropriate position; the coaxial rotational connection between the support base 34 and the cylinder shell 14 not only ensures that the rotating shell 13 and its brush roller 11 can rotate smoothly, but also supports the rotating shell 13 and restricts its direction of movement to avoid unnecessary shaking; the setting of the connecting frame 33 and the support frame 32 further enhances the stability of the frame 31, ensuring that the entire device will not be displaced or deformed due to external forces during operation.

[0072] The reasonable layout and connection of the cleaning agent spraying component 8 and the clean water spraying component 9 can ensure that the cleaning agent and clean water are accurately and evenly sprayed onto the surface of the persimmon, while ensuring the independent and continuous supply of cleaning agent and clean water throughout the cleaning process, so that the cleaning work can be carried out without interruption.

[0073] A highly efficient method for preparing color-protecting persimmon pulp, comprising the following detailed steps:

[0074] Step 1, Raw material selection: Select persimmons that are 80% ripe, have an orange-red skin, and are free from disease, pests, mold, and mechanical damage;

[0075] Step 2, Cleaning and Disinfection: In the cleaning stage, first rinse the surface dust and impurities with clean water, then use a fruit and vegetable cleaner to clean the oily stains on the surface of the persimmons, and finally rinse again with clean water.

[0076] During the disinfection stage, soak the persimmons in an aqueous solution of hypochlorous acid with an effective concentration of 100-200 ppm for 3-5 minutes for disinfection, and then rinse them with clean water.

[0077] Step 3, ripening and astringency removal treatment: After washing, the persimmons are soaked in a 0.05%~0.1% ethephon solution for 1-2 minutes, then dried and transferred to a sealed space. The temperature is controlled at 25-28℃ for 3-5 days. The persimmons are taken out when the peel turns completely red and the fruit softens.

[0078] Step 4, crushing, pulping and simultaneous color protection: After removing the stems from the softened persimmons, crush the processed persimmons with a crusher, and then put them into a pulping machine for pulping. When pulping, add 20-30% purified water according to the weight of the persimmons to reduce the viscosity of the pulp.

[0079] Add the compound color-protecting agent directly during pulping. The compound color-protecting agent is a 0.01%-0.02% sodium bisulfite aqueous solution, but the residual amount must be controlled to ≤10mg / kg.

[0080] Step 5, Filtration: Coarsely filter through a 60-mesh stainless steel sieve to remove residual fruit pulp, coarse fibers and other impurities;

[0081] Step 6, Packaging and Sterilization: The filtered persimmon pulp is placed into high-barrier flexible bags or PP bottles, sealed, and then sterilized by high static pressure of 500-600Mpa for 15-20 minutes.

[0082] Step 7, Storage: The sterilized persimmon pulp is stored in an environment at -18℃ and away from light.

[0083] The working principle of this invention is as follows: This invention allows multiple brush rollers 11 on the pre-washing assembly 1 and the post-washing assembly 2 to simultaneously rotate and revolve, in conjunction with the cleaning agent spraying assembly 8 and the clean water spraying assembly 9, to perform multi-stage cleaning of the persimmons, removing visible impurities, invisible impurities, and oily impurities from the surface of the persimmons. Specifically, when the connecting shaft 64 rotates, it drives the inner shaft 19 and the rotating active bevel gear 17. The active bevel gear 17 then drives multiple driven bevel gears 18 to rotate, thereby causing the multiple brush rollers 11 to rotate. When the connecting shaft 64 rotates, it drives the upper bevel gear 62 to rotate synchronously. The upper bevel gear 62 then drives the lower bevel gear 61 to rotate through the redirecting bevel gear 63. The lower bevel gear 61 drives the cylinder shell 14 to rotate, thus causing the rotating shell 13 to rotate. The rotating shell 13 can then drive the multiple brush rollers 11 to rotate, achieving the revolve of the multiple brush rollers 11.

A method for preparing highly efficient color-protecting persimmon pulp, characterized in that: Includes the following steps: Step 1, Raw material selection: Select persimmons that are 80% ripe, have an orange-red skin, and are free from disease, pests, mold, and mechanical damage; Step 2, Cleaning and Disinfection: In the cleaning stage, first rinse the surface dust and impurities with clean water, then use a fruit and vegetable cleaner to clean the oily stains on the surface of the persimmons, and finally rinse again with clean water. During the disinfection stage, soak the persimmons in an aqueous solution of hypochlorous acid with an effective concentration of 100-200 ppm for 3-5 minutes for disinfection, and then rinse them with clean water. Step 3, ripening and astringency removal treatment: After washing, the persimmons are soaked in a 0.05-0.1% ethephon solution for 1-2 minutes, then dried and transferred to a sealed space. The temperature is controlled at 25-28℃ for 3-5 days. The persimmons are taken out when the peel turns completely red and the fruit softens. Step 4, crushing, pulping and simultaneous color protection: After removing the stems from the softened persimmons, crush the processed persimmons with a crusher, and then put them into a pulping machine for pulping. When pulping, add 20-30% purified water according to the weight of the persimmons to reduce the viscosity of the pulp. Add the compound color-protecting agent directly during pulping. The compound color-protecting agent is a 0.01%-0.02% sodium bisulfite aqueous solution, but the residual amount must be controlled to ≤10mg / kg. Step 5, Filtration: Coarsely filter through a 60-mesh stainless steel sieve to remove residual fruit pulp, coarse fibers and other impurities; Step 6, Packaging and Sterilization: The filtered persimmon pulp is placed into high-barrier flexible bags or PP bottles, sealed, and then sterilized by high static pressure of 500-600Mpa for 15-20 minutes. Step 7, Storage: The sterilized persimmon pulp is stored in an environment at -18℃ and away from light.
