Description

Technical Field

[0001] This invention relates to the field of hickory processing technology, specifically to an integrated astringency removal and cleaning device for hickory from the Dabie Mountains. Background Technology

[0002] Walnuts, one of the world's four major nuts, are rich in high-quality protein, unsaturated fatty acids, various vitamins, and minerals, making them a highly nutritious and healthy food. After harvesting, walnuts are covered with mud, dust, residual sap from the green husk, and microorganisms. The sap from the green husk contains oxidases, which can easily cause browning on the walnut surface, affecting its appearance. Furthermore, the inner seed coat (thin brown skin) of the walnut kernel contains high concentrations of tannic acid and polyphenolic compounds, which are astringent substances. These substances combine with proteins in the oral mucosa, producing an astringent sensation that severely impacts the taste and product quality. Therefore, astringency removal is a core step in walnut processing and directly determines the product's market competitiveness.

[0003] An existing patent (publication number: CN108634345B) discloses a multi-stage walnut cleaning device with linkage, comprising a body, a feeding chamber, a primary cleaning chamber, and a secondary cleaning chamber. The feeding chamber is inclinedly arranged on the upper left side of the body, and an inlet is arranged on the upper left side of the feeding chamber, which communicates with the feeding chamber. The primary cleaning chamber is arranged on the upper right side of the body, and the feeding chamber is connected to the primary cleaning chamber through a connecting bend. The secondary cleaning chamber is arranged below the primary cleaning chamber. It can perform multi-stage cleaning of walnuts and can clean all surfaces of the walnuts, improving the cleaning effect. It can also realize the recycling of water, making it energy-saving, efficient, and highly practical.

[0004] Currently, some walnut deastringency cleaning equipment has limitations in actual use. Due to the deep texture, numerous folds and narrow gaps of the walnut shell, ordinary water washing and brush friction can only remove surface dust. The mud, green peel residue, and gum dirt embedded in the grooves, folds and gaps of the walnut shell cannot be automatically removed by static soaking. The water flow does not have a turbulent effect, and stubborn impurities in the gaps adhere for a long time, resulting in poor cleaning and high residue rate. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated astringency removal and cleaning device for Dabie Mountain walnuts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated astringency removal and cleaning device for Dabie Mountain walnuts, comprising a device shell, and further comprising: A mounting bracket is installed on the outer surface of the equipment housing. A partition mesh plate is bolted to the horizontal direction inside the equipment housing. A drain valve is connected to the lower surface of the equipment housing. An auxiliary mechanism for cleaning and removing astringency from walnuts is installed on one side of the fixed frame. A circulation mechanism for circulating the cleaning liquid is provided on one side of the equipment housing, and a collection mechanism for collecting walnuts is provided at one end of the equipment housing.

[0007] Preferably, the auxiliary mechanism includes an air pump installed on one side of the fixed frame, the output end of the air pump is connected to an air supply pipe, the input end of the air pump is connected to a dust filter, and one side of the air supply pipe is connected to two mounting components.

[0008] Preferably, the two mounting components are internally connected by a connecting shaft, and the end of the connecting shaft is connected to a cleaning roller brush installed inside the equipment housing.

[0009] Preferably, the outer surface of the cleaning roller brush is evenly provided with a plurality of air jet holes, and the outer surface of the connecting shaft is fitted with a sealed bearing embedded in the inner wall of the equipment housing.

[0010] Preferably, the circulation mechanism includes a filter element connected to one side of the equipment housing, a mounting base is installed vertically inside the filter element, a filter screen plate is fixed vertically inside the mounting base by screws, and a protective net is provided on one side of the filter screen plate and fixed inside the mounting base.

[0011] Preferably, two locking blocks that are fixedly connected to the filter element are inserted into both sides of the mounting base. A return pipe is connected to one side of the filter element, and a high-pressure pump fixed inside the mounting frame is connected to the end of the return pipe.

[0012] Preferably, the output end of the high-pressure pump is connected to a first delivery pipe, and the outer surface of the first delivery pipe is connected to two connectors. Each of the two connectors is equipped with a water impeller. The water impeller is rotatably connected to the cleaning roller brush via a rotating shaft. A fixed bearing embedded in the inner wall of the connector is sleeved on one side of the water impeller. The end of the first delivery pipe is connected to a water outlet component fixed inside a fixed frame.

[0013] Preferably, the collection mechanism includes a discharge component installed at one end of the equipment housing, an installation pipe fixed to one side of the discharge component, and a plurality of water spray heads connected to the outer surface of the installation pipe.

[0014] Preferably, the input end of the mounting pipe is connected to a second conveying pipe, the second conveying pipe is connected to the first conveying pipe, the side wall of the discharge component is fixed with a drive motor by bolts, the power output shaft of the drive motor is fixed with a reducer by a coupling, and the output end of the reducer is connected to a drive roller by a key.

[0015] Preferably, a conveyor belt plate is installed on the outer surface of the drive roller, both ends of the drive roller are rotatably connected to the inner wall of the discharge component through bearings, a driven roller rotatably connected to the discharge component is connected to one side of the conveyor belt plate, a plurality of through holes are equidistantly opened on the outer surface of the conveyor belt plate, and a guide plate is fixed at the front end of the discharge component.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention introduces suitable microbial tannin enzymes into the cleaning solution to target and hydrolyze galloyl compounds. By directly decomposing tannins themselves using biological enzymes, it removes astringency from the root, leaving no chemical residue and achieving a green deastringency effect. Through the vent holes on the connecting shaft, air enters the cleaning roller brush and is ejected through several air jet holes on the surface of the cleaning roller brush. The ejected air forms bubbles in the cleaning solution and floats upward from the top of the separator mesh. The bubbles continuously impact and penetrate the grooves, folds, and tiny gaps of the walnut shell, effectively removing embedded mud, green peel residue, and stubborn gum dirt. This overcomes the shortcomings of incomplete cleaning by static water washing. Furthermore, the buoyancy and turbulence generated during the bubble's ascent continuously lift, tumble, and disperse the walnut material in the tank, significantly improving the overall cleanliness and effectively reducing impurity residue. This invention uses a high-pressure pump to draw cleaning liquid from inside the equipment casing into the filter element. The cleaning liquid undergoes fine filtration through the filter screen, effectively reducing impurities in the cleaning liquid. The filtered cleaning liquid is then drawn out by the high-pressure pump through the return pipe, and then transported through the first delivery pipe to two connecting parts. When the high-pressure cleaning liquid passes through the connecting parts, it drives the water impeller to rotate, which in turn drives the cleaning roller brush to rotate, thus cleaning the walnuts inside the equipment.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Please see Figures 1-8 As shown, an integrated astringency removal and cleaning device for Dabie Mountain walnuts includes a housing 1, and also includes: A mounting bracket 2 is installed on the outer surface of the equipment housing 1. A partition mesh plate 3 is fixed horizontally inside the equipment housing 1 by bolts. A drain valve 7 is connected to the lower surface of the equipment housing 1. A control box is installed on one side of the equipment housing 1. The control box contains a programmable logic controller (PLC) for receiving signals and issuing execution instructions, a touch screen display (HMI) for human-machine interface for setting parameters, viewing status and switching modes, an air switch for overload / short circuit protection of the main power supply of the equipment, and an AC contactor for controlling the start and stop of high-power actuators (motors, pumps). An auxiliary mechanism for cleaning and de-astringing walnuts is installed on one side of the fixed frame 2. A circulation mechanism for circulating the cleaning liquid is provided on one side of the equipment housing 1. A collection mechanism for collecting walnuts is provided at one end of the equipment housing 1.

[0021] It should be noted that the fixing frame 2 is made of stainless steel, which gives it high mechanical strength. The inner surface of the equipment shell 1 is coated with an anti-corrosion coating to achieve corrosion protection. The partition mesh plate 3 is punched with a stamping machine to achieve the function of layering.

[0022] The auxiliary mechanism includes an air pump 4 installed on one side of the fixed frame 2. The output end of the air pump 4 is connected to an air supply pipe 41, and the input end of the air pump 4 is connected to a dust filter. Two mounting parts 42 are connected to one side of the air supply pipe 41. The air pump 4 can draw in external air through the dust filter and then deliver the air to the two mounting parts 42 through the air supply pipe 41.

[0023] The two mounting parts 42 are internally connected by a connecting shaft 43. The end of the connecting shaft 43 is connected to a cleaning roller brush 44 installed inside the equipment housing 1. Air is allowed to enter the cleaning roller brush 44 through the vent hole provided on the connecting shaft 43.

[0024] The outer surface of the cleaning roller brush 44 is evenly provided with several air jet holes 45, and the outer surface of the connecting shaft 43 is fitted with a sealed bearing 46 embedded in the inner wall of the equipment housing 1. Air is ejected through the several air jet holes 45 on the surface of the cleaning roller brush 44, causing the ejected air to form bubbles in the cleaning liquid and float upward from the top of the separator mesh plate 3. The bubbles continuously impact and penetrate into the grooves, folds and small gaps of the walnut shell, which can efficiently remove embedded mud, green skin residue and stubborn gum dirt, overcoming the defects of incomplete cleaning by static water washing. In addition, the buoyancy and turbulence generated during the rising of the bubbles can continuously lift, roll and disperse the walnut material in the tank, greatly improving the overall cleanliness and effectively reducing the residue of impurities.

[0025] It should be noted that the brushes on the surface of the cleaning roller brush 44 can be replaced according to the different qualities of walnuts. A one-way valve is installed at the connection between the connecting shaft 43 and the cleaning roller brush 44, so that air can only enter the cleaning roller brush 44 through the connecting shaft 43, while external cleaning liquid cannot enter the connecting shaft 43, reducing the possibility of cleaning liquid leakage. In addition, a spring-loaded anti-backflow diaphragm is installed inside the cleaning roller brush 44 and inside the air jet hole 45. The diaphragm is only opened by the airflow when the air pump 4 supplies air to achieve air jet, and automatically closes the air jet hole 45 when the air supply stops, which can further reduce the backflow of cleaning liquid. Furthermore, a gas-liquid separator (existing technology) can be installed between the air supply pipe 41 and the mounting part 42. Even if a small amount of liquid accidentally enters the air supply pipe 41, it can be quickly separated and discharged, thoroughly protecting the air pump 4 and the dust filter from damage by liquid.

[0026] The circulation mechanism includes a filter element 5 connected to one side of the equipment housing 1. A mounting base 51 is vertically installed inside the filter element 5. A filter screen plate 52 is vertically fixed inside the mounting base 51 by screws. A protective net 53 is fixed to one side of the filter screen plate 52 within the mounting base 51. An elastic positioning pin is provided on the contact surface between the inner wall of the filter element 5 and the mounting base 51. After the locking block 54 is inserted into place, the positioning pin automatically engages with the positioning hole of the mounting base 51 to prevent loosening due to vibration. During disassembly, pressing the positioning pin allows the mounting base 51 to be pulled out. This equipment utilizes biological enzymes to directly decompose tannins themselves, removing astringency from the source. With no chemical residue, it achieves a green deastringency removal effect. Furthermore, an electric heating tube and a temperature sensor are installed on the inner wall of the equipment shell 1 and below the partition mesh plate 3. The temperature sensor monitors the temperature of the cleaning solution in real time, and the electric heating tube automatically controls the temperature at the optimal activity temperature of tannin enzyme (25-35℃) to ensure a stable and consistent deastringency removal effect. At the same time, the high-pressure pump 56 is activated to draw the cleaning solution from the equipment shell 1 into the filter element 5. Through the protective net 53 set in the mounting base 51, the initial filtration can be achieved. The cleaning solution then passes through the filter mesh plate 52 for fine filtration, thereby effectively reducing impurities in the cleaning solution.

[0027] Two clips 54 are inserted and connected to the filter element 5 on both sides of the mounting base 51. A return pipe 55 is connected to one side of the filter element 5. A high-pressure pump 56 fixed inside the mounting bracket 2 is connected to the end of the return pipe 55. The filtered cleaning liquid is drawn out by the high-pressure pump 56 through the return pipe 55.

[0028] The output end of the high-pressure pump 56 is connected to a first delivery pipe 57. The outer surface of the first delivery pipe 57 is connected to two connectors 58. Water impellers 59 are installed inside the two connectors 58. The water impellers 59 are rotatably connected to the cleaning roller brush 44 through a rotating shaft. A fixed bearing 510 embedded in the inner wall of the connector 58 is sleeved on one side of the water impeller 59. The end of the first delivery pipe 57 is connected to a water outlet 511 fixed inside the fixed frame 2. When the high-pressure flowing cleaning liquid passes through the connector 58, it will drive the water impeller 59 to rotate, thereby driving the cleaning roller brush 44 to rotate, which can clean the walnuts inside the equipment. The fixed bearing 510 can ensure the stability of the water impeller 59 during rotation. The cleaning liquid after passing through the two connectors 58 will be sprayed into the equipment shell 1 through the water outlet 511, so that the cleaning liquid can be reused.

[0029] It should be noted that the high-pressure pump 56 can deliver the extracted cleaning fluid under high pressure, and the high-pressure delivery of the cleaning fluid can effectively drive the water impeller 59 to rotate, thereby ensuring that the cleaning roller brush 44 effectively cleans the walnuts. In addition, a flow regulating valve can be set between the first delivery pipe 57 and the connector 58 to manually adjust the flow rate of the cleaning fluid entering the connector 58, stabilize the speed of the water impeller 59, ensure that the cleaning roller brush 44 has a uniform brushing force, and avoid damage to the walnuts.

[0030] The collection mechanism includes a discharge component 6 installed at one end of the equipment housing 1. An installation pipe 61 is fixed to one side of the discharge component 6. Several water spray heads 62 are connected to the outer surface of the installation pipe 61. The input end of the installation pipe 61 is connected to a second conveying pipe 63. The second conveying pipe 63 is connected to the first conveying pipe 57. The cleaning liquid delivered by the high-pressure pump 56 to the first conveying pipe 57 will be partially diverted to the second conveying pipe 63 and then enter the installation pipe 61. It will be sprayed onto the conveyor belt plate 67 through the water spray heads 62 set on the installation pipe 61, which can rinse the walnuts being conveyed, further reducing impurities on the surface of the walnuts. In addition, the water spray head 62 is a universal adjustable spray head, which can be manually adjusted to adjust the rinsing angle, covering the entire surface of the walnuts, completely eliminating rinsing blind spots, and improving the cleanliness of secondary rinsing.

[0031] The side wall of the discharge part 6 is fixed with a drive motor 64 by bolts. The power output shaft of the drive motor 64 is fixed with a reducer 65 by a coupling. The output end of the reducer 65 is connected to the drive roller 66 by a key. The drive motor 64 drives the reducer 65 to run, which in turn drives the drive roller 66 to rotate. With the cooperation of the driven roller 68, it can drive the conveyor belt plate 67 to run. The lifting plate on the outer surface of the conveyor belt plate 67 can transport the walnuts upward.

[0032] A conveyor belt plate 67 is installed on the outer surface of the drive roller 66, and the conveyor belt plate 67 is provided with a flexible baffle. The flexible material prevents the walnuts from bumping and also effectively prevents the walnuts from falling from both sides of the conveyor belt. Both ends of the drive roller 66 are rotatably connected to the inner wall of the discharge part 6 through bearings. A driven roller 68 is connected to one side of the conveyor belt plate 67 and is rotatably connected to the discharge part 6. Several through holes 69 are equidistantly opened on the outer surface of the conveyor belt plate 67. A guide plate 610 is fixed at the front end of the discharge part 6. The sprayed cleaning liquid will flow into the equipment housing 1 through the through holes 69 on the surface of the conveyor belt plate 67. The cleaned walnuts are guided out and collected by the guide plate 610.

[0033] It should be noted that a flow regulating valve can be installed at the connection between the second delivery pipe 63 and the first delivery pipe 57 to regulate the flow rate of the cleaning liquid in the second delivery pipe 63. When there are no residual impurities on the surface of the walnut, a small amount of cleaning liquid can be delivered for secondary rinsing. When there are impurities on the surface of the walnut, the flow rate of the cleaning liquid can be increased.

[0034] It is worth noting that the technical features proposed in this technical solution, such as the equipment housing 1, the circulation mechanism, the high-pressure pump 56, and the drive motor 64, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in the field. This technical solution will not elaborate further.

[0035] Working Principle: Before using the Dabie Mountain walnut de-astringency and cleaning integrated equipment, first place the equipment shell 1 in a suitable position. The fixed frame 2 ensures the stability of the equipment. Power on the control box, close the main air switch, perform PLC self-test, and the touch screen displays that the equipment is ready. Then, put the walnuts to be processed into the equipment shell 1. The set separator mesh 3 can block the walnuts in the upper part of the equipment. Then, add cleaning solution into the equipment, and add appropriate microbial tannin enzymes to the cleaning solution to target and hydrolyze galloyl compounds. The biological enzymes directly decompose the tannins themselves, removing astringency from the root, leaving no chemical residue, and achieving a green de-astringency effect. The temperature sensor collects the temperature of the cleaning solution and transmits it to the temperature controller and PLC to compare with the set value (25). (-35℃) When the temperature is low, the electric heating element is activated to heat the solution. Heating automatically stops when the target temperature is reached, maintaining a constant enzyme activity temperature. Simultaneously, the high-pressure pump 56 starts, drawing the cleaning solution from the equipment casing 1 into the filter element 5. The solution undergoes initial filtration through the protective net 53 inside the mounting base 51. The cleaning solution then passes through the filter screen 52 for further filtration, effectively reducing impurities. A locking block 54 inside the filter element 5 and slots on both sides of the mounting base 51 allow the operator to pull the mounting base 51 vertically, removing it from the filter element 5 for easy cleaning and replacement of the internal filter screen 52. The filtered cleaning solution is then drawn out by the high-pressure pump 56 through the return pipe 55, and then... High-pressure cleaning fluid is delivered through the first conveying pipe 57 to the two connecting parts 58. As the high-pressure cleaning fluid passes through the connecting parts 58, it drives the impeller 59 to rotate, which in turn drives the cleaning roller brush 44 to rotate, effectively cleaning the inside of the equipment. The fixed bearing 510 ensures the stability of the impeller 59 during rotation. After passing through the two connecting parts 58, the cleaning fluid is sprayed into the equipment casing 1 through the water outlet 511, allowing for reuse. Simultaneously, the air pump 4 operates during the circulation of the cleaning fluid, drawing in external air through a dust filter and then delivering it through the air supply pipe 41 to the two mounting parts 42. The air passes through the vent holes on the connecting shaft 43. The connecting shaft 43 enters the cleaning roller brush 44 and is then ejected through several air jet holes 45 on the surface of the cleaning roller brush 44. The ejected air forms bubbles in the cleaning liquid and floats upward from the top of the separator mesh plate 3. The bubbles continuously impact and penetrate the grooves, folds, and tiny crevices of the walnut shell, effectively removing embedded mud, green peel residue, and stubborn gum dirt. This overcomes the shortcomings of incomplete cleaning by static water washing. Furthermore, the buoyancy and turbulence generated during the bubble's ascent continuously lift, tumble, and disperse the walnut material in the tank, significantly improving overall cleanliness and effectively reducing impurity residue. The sealed bearing 46 ensures that the mounting part 42 does not rotate when the cleaning roller brush 44 drives the connecting shaft 43, thus ensuring normal air delivery.After being cleaned by the cleaning roller brush 44, the walnuts enter the input end of the discharge part 6. The drive motor 64 drives the reducer 65, which in turn drives the drive roller 66 to rotate. With the cooperation of the driven roller 68, the drive roller 66 drives the conveyor belt 67. The lifting plates on the outer surface of the conveyor belt 67 can transport the walnuts upward. The cleaning liquid delivered by the high-pressure pump 56 to the first conveying pipe 57 is partially diverted to the second conveying pipe 63 and then enters the mounting pipe 61. It is sprayed onto the conveyor belt 67 through the water spray head 62 on the mounting pipe 61 to rinse the walnuts being transported, further reducing impurities on the surface of the walnuts. The sprayed cleaning liquid flows into the equipment housing 1 through the through holes 69 on the surface of the conveyor belt 67. The cleaned walnuts are discharged and collected by the guide plate 610. After the equipment is used, the drain valve 7 at the bottom of the equipment housing 1 can be opened to discharge the wastewater.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
