Description

Technical Field

[0001] This invention relates to the field of wheat washing technology, and more specifically to a small-scale mixed water washing wheat washing machine. Background Technology

[0002] As a major global food and feed ingredient, wheat's safety and quality are directly related to human and animal health and food safety. During harvesting, storage, and transportation, wheat is highly susceptible to contamination by various microbial toxins due to adverse conditions such as humidity and heat. Among these, aflatoxin, vomitoxin, zearalenone, and ochratoxin are the most common and pose serious risks. These toxins are highly carcinogenic, teratogenic, and immunosuppressive, and strict limits have been established in various countries. Therefore, efficient and safe detoxification treatment of raw wheat before milling has become a crucial preliminary step for the grain processing industry to ensure the safety of end products and mitigate trade risks.

[0003] Chinese patent (publication number: CN104759306B) discloses a small mixed water washing machine for wheat washing, including a frame, a washing tank, an auger tank, a dewatering cylinder, and a wastewater collector installed directly below the auger tank. The washing auger is installed in the auger tank, which is inclined at 25±2°. A screen is installed at the bottom of the auger tank for draining water, and a return water tank is provided below the screen. The bottom end of the auger tank is connected to the washing tank. A sand and gravel auger is installed at the bottom of the washing tank. A spray pipe is installed in the upper part of the auger tank, and the spray flow rate is controlled by a flow monitoring controller installed on the inlet pipe.

[0004] The core design of this patent and traditional wheat washing machines (such as destone washing machines and auger washing machines) is to remove mud, sand, stones and light impurities. Their working mechanism is inefficient at removing microbial toxins with low solubility and strong adsorption. Simple water rinsing and soaking are insufficient to remove toxins that are tightly bound to the wheat matrix. Summary of the Invention

[0005] The purpose of this invention is to provide a small-scale mixed water washing machine for wheat to solve the above problems.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A small-scale mixed water washing machine for wheat includes a bottom tank, which consists of a hydrogen peroxide tank, a first collection tank, and a second collection tank distributed from right to left. Both the first and second collection tanks are equipped with vibrators. Two outer baffles are fixedly installed on the top of the bottom tank, and an inner conveyor line is arranged between the two outer baffles. Guide rails are provided on the inner sides of both outer baffles. A first and second recessed portion are provided at the bottom of the guide rails. The first recessed portion is located directly above the hydrogen peroxide tank, and the second recessed portion is located to the left of the second collection tank. An outer conveyor belt is slidably connected to the guide rails and is sleeved on the outside of the inner conveyor line. Several fixed mesh plates are fixedly installed on the outer surface of the inner conveyor line, and several telescopic mesh plates are hinged to the inner side of the outer conveyor belt. The telescopic mesh plates are slidably connected to the corresponding fixed mesh plates.

The high-pressure flushing components are located directly above the second collection tank. A centrifugal dewatering component is installed on the left side of the bottom tank. A negative pressure conveying component is installed on the top of the centrifugal dewatering component. The negative pressure conveying component can transport the wheat located in the second sinking part to the centrifugal dewatering component and can suck out the dehydrated wheat in the centrifugal dewatering component.

[0009] Furthermore, both the first collection tank and the second collection tank are provided with a drain outlet at the bottom. The first collection tank is provided with multiple sets of vibrators, which are linearly distributed along the conveying direction of the inner conveyor line. The second collection tank is provided with one set of vibrators, which is located near the left side of the second collection tank.

[0010] Furthermore, a hydrogen peroxide controller is installed on the right side of the hydrogen peroxide pool. The hydrogen peroxide controller consists of a sensor, a PLC controller, a liquid pump, and a storage tank.

[0011] Furthermore, guide rollers are rotatably installed on both sides of the outer conveyor belt, and the guide rail has wheel grooves inside, in which the guide rollers are inserted.

[0012] Furthermore, fixed outer frame rods are provided on both sides of the fixed mesh plate, and telescopic outer frame rods are provided at both ends of the telescopic mesh plate. Both the fixed outer frame rods and the telescopic outer frame rods are tightly attached to the inner wall of the outer baffle. A sliding groove is provided on the outer side of the telescopic outer frame rod, and a sliding rod is provided on the outer side of the fixed outer frame rod. The sliding rod is slidably connected in the sliding groove.

[0013] Furthermore, the telescopic outer frame rod is connected to the inner wall of the outer conveyor belt through an elastic connecting part, and the telescopic mesh plate is made of metal mesh, with one end of the metal mesh fixedly connected to the inner wall of the outer conveyor belt.

[0014] Furthermore, the outer baffle has an upwardly angled feeding port located above the inner conveyor line and inside the outer conveyor belt, with the feeding hopper connected to the feeding port.

[0015] Furthermore, the high-pressure flushing assembly includes a water storage tank located in front of the second collection tank, a high-pressure water pump located above the water storage tank, a flushing nozzle fixedly installed on the outer side of the outer baffle, the flushing nozzle being connected to the outlet of the high-pressure water pump, the outlet of the flushing nozzle being obliquely downward and located below the inner conveyor line and inside the outer conveyor belt.

[0016] Furthermore, the centrifugal dehydration assembly includes a centrifuge located on the left side of the bottom tank, a drive motor located at the bottom of the centrifuge, a centrifugal inner cylinder rotatably mounted inside the centrifuge, the centrifugal inner cylinder being connected to the output end of the drive motor, and the bottom of the centrifugal inner cylinder having a conical design.

[0017] Furthermore, the negative pressure conveying assembly includes a negative pressure hopper fixedly installed on the top of the centrifuge. A negative pressure fan is fixedly installed in the center of the top of the negative pressure hopper. Two sets of feed pipes are provided on the top of the negative pressure hopper, with the two sets of feed pipes located on both sides of the negative pressure fan. A material port is opened on the outer side of each of the two outer baffles, located at the second sinking part. The two sets of feed pipes are connected to the two material ports respectively. Each set of feed pipes is equipped with a feed solenoid valve. A three-way solenoid valve is provided at the bottom outlet of the negative pressure hopper. One port of the three-way solenoid valve is connected to the centrifuge inlet, and the other port is equipped with a discharge pipe. A suction pipe is provided on the top of the negative pressure hopper. The lower half of the suction pipe is inserted into the centrifuge inner cylinder, and the center line of the lower half of the suction pipe coincides with the rotation axis of the centrifuge inner cylinder. A suction solenoid valve is provided on the suction pipe.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention first employs hydrogen peroxide immersion to thoroughly separate the wheat from the oxidant after the oxidation treatment achieves the desired effect (sterilization and degradation). Then, high-frequency vibration rapidly drains the large amount of oxidized liquid within 15-30 seconds. Next, high-pressure water jets are used to rinse the wheat in a continuous flow. Finally, centrifugal force (>300G) generated by high-speed rotation removes surface water within 1-3 minutes, reducing the moisture content to below 15%. Through an innovative multi-stage synergistic treatment module design, this invention achieves efficient degradation and removal of various microbial toxins in wheat while ensuring the quality of wheat processing.

[0020] This invention employs a through-process method, which can quickly connect the various steps of wheat washing, resulting in high processing efficiency and effectively preventing excessive oxidation of wheat. At the same time, by controlling the conveying speed, it can achieve precise control of soaking time and is applicable to wheat washing with different levels of contamination.

[0021] This invention employs a double-layer conveying method, with the double-layer conveyor belts connected by a fixed mesh plate and a telescopic mesh plate. This ensures stable transmission of the double-layer conveyor belts. Due to the setting of the first sinking part, after the wheat leaves the hydrogen peroxide solution, the angle between the telescopic mesh plate and the outer conveyor belt decreases, which exerts a squeezing effect on the wheat and can initially squeeze out the hydrogen peroxide solution, reducing the waste of hydrogen peroxide solution and saving costs.

[0022] This invention, through the setting of a negative pressure conveying component, can simultaneously draw wheat into the centrifugal dehydration component and discharge the dehydrated wheat from the centrifugal dehydration component. The equipment has a compact structure and small size. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1, as Figures 1-7 As shown, a small mixed water washing machine for wheat includes a bottom pool, which consists of a hydrogen peroxide pool 1, a first collection pool 2, and a second collection pool 3 distributed from right to left. Vibrators 21 are installed inside the first collection pool 2 and the second collection pool 3. Two outer baffles 4 are fixedly installed on the top of the bottom pool. An inner conveyor line 9 is arranged between the two outer baffles 4. Guide rails 41 are arranged on the inner side of the two outer baffles 4. A first sinking part 42 and a second sinking part 43 are arranged at the bottom of the guide rails 41. The first sinking part 42 is located directly above the hydrogen peroxide pool 1, and the second sinking part 43 is located to the left of the second collection pool 3. An outer conveyor belt 10 is slidably connected in the guide rails 41. The outer conveyor belt 10 is sleeved on the outside of the inner conveyor line 9. Several fixed mesh plates 11 are fixedly installed on the outer surface of the inner conveyor line 9. Several telescopic mesh plates 12 are hinged to the inner side of the outer conveyor belt 10. The telescopic mesh plates 12 are slidably connected to the corresponding fixed mesh plates 11.

[0033] A feeding hopper 5 is mounted on the top of the two outer baffles 4. A high-pressure flushing assembly 6 is installed on the inner wall of both outer baffles 4. The high-pressure flushing assembly 6 is located directly above the second collection tank 3. A centrifugal dewatering assembly 7 is installed on the left side of the bottom tank. A negative pressure conveying assembly 8 is installed on the top of the centrifugal dewatering assembly 7. The negative pressure conveying assembly 8 can convey the wheat located in the second sinking part 43 to the centrifugal dewatering assembly 7 and can suck out the dehydrated wheat in the centrifugal dewatering assembly 7.

[0034] Preferably, guide rollers 101 are rotatably installed on both sides of the outer conveyor belt 10, and the guide rail 41 has a wheel groove inside, in which the guide rollers 101 are inserted.

[0035] Preferably, the outer baffle 4 has an upwardly angled feed port located above the inner conveyor line 9 and inside the outer conveyor belt 10, and the feed hopper 5 is connected to the feed port.

[0036] Cleaning steps:

[0037] Feeding: Pour the pre-treated wheat (airflow impurity removal, with only some dust, impurities, and mold adhering to the surface of the wheat) into the feeding hopper 5. Open the outlet of the feeding hopper 5, and the wheat in the feeding hopper 5 will automatically flow into the space between the upper surface of the inner conveyor line 9 and the outer conveyor belt 10 under the action of gravity. As the inner conveyor line 9 rotates, the wheat is conveyed from left to right. When it reaches the rightmost end, the wheat falls onto the outer conveyor belt 10.

[0038] Oxidation treatment: Under the guidance of the first sinking part 42, the outer conveyor belt 10 enters the hydrogen peroxide pool 1 for soaking. The soaking time is precisely controlled by controlling the conveying speed of the inner conveyor line 9 to control the residence time of wheat in the hydrogen peroxide pool 1. The soaking time is usually 30-90 seconds. After soaking, the wheat is first separated from the hydrogen peroxide solution at an angle under the guidance of the first sinking part 42. Under the action of gravity, the wheat will accumulate downward on the telescopic mesh plate 12 and the fixed mesh plate 11. At this time, the angle between the telescopic mesh plate 12, the fixed mesh plate 11 and the outer conveyor belt 10 decreases. The telescopic mesh plate 12 and the fixed mesh plate 11 will exert a certain squeezing force on the wheat. At this point, the telescopic mesh plate 12 and the outer conveyor belt 10 form a V-shaped funnel shape, which facilitates the drainage of residual hydrogen peroxide solution in the wheat and reduces the waste of hydrogen peroxide solution.

[0039] Instant separation: The outer conveyor belt 10 transports wheat to the top of the first collection pool 2 via the telescopic mesh plate 12. The vibrator 21 causes the outer conveyor belt 10 to vibrate at high frequency. Since the telescopic mesh plate 12 can slide relative to the fixed mesh plate 11, the vibration has little impact on the inner conveyor line 9. Through high-frequency vibration screening, the residual hydrogen peroxide solution in the wheat is quickly separated, and the hydrogen peroxide solution is quickly discharged within 15-30 seconds.

[0040] High-pressure washing: The outer conveyor belt 10 transports the wheat to the top of the second collection tank 3. At this time, the wheat is basically spread out on the outer conveyor belt 10 under high-frequency vibration, ensuring that the wheat can be washed quickly and thoroughly. The high-pressure washing component 6 washes the spread wheat under high pressure, and the vibrator 21 in the second collection tank 3 causes the outer conveyor belt 10 to vibrate at high frequency, removing the dirty water containing trace amounts of oxidants and pollutants.

[0041] Centrifugal dehydration: The outer conveyor belt 10 transports the wheat to the second sinking part 43, where the wheat is piled up and concentrated by the negative pressure conveying component 8 and transported to the centrifugal dehydration component 7 for centrifugal dehydration. The centrifugal force (>300G) generated by the high-speed rotation removes the surface water within 1-3 minutes, reducing the moisture content to below 15%.

[0042] Through the above steps, wheat can be thoroughly cleaned, residual oxidants can be completely removed, and rapid separation and dehydration can be achieved, ensuring wheat quality and safety.

[0043] Points to note:

[0044] Time is life: The entire process of “oxidation → drainage → rinsing → dehydration” should be compact and continuous, with the total time controlled within 10-15 minutes, in order to minimize the potential impact of oxidants on the internal structure of wheat.

[0045] Water quality requirements: The water used for rinsing must be clean to prevent secondary pollution.

[0046] Food safety: All chemical reagents used must be food-grade and comply with relevant regulations and standards.

[0047] Material compatibility: Components that come into direct contact with oxidants (external conveyor belt 10, fixed mesh plate 11, telescopic mesh plate 12, external baffle 4, bottom pool, etc.) must be made of oxidation-resistant materials (such as 316L stainless steel, specific engineering plastics) to prevent corrosion.

[0048] Example 2: Based on the above examples, a specific structure of a first collection pool 2 and a second collection pool 3 is provided;

[0049] Both the first collection tank 2 and the second collection tank 3 are equipped with sewage outlets at the bottom. The first collection tank 2 is equipped with multiple sets of vibrators 21, which are linearly distributed along the conveying direction of the inner conveyor line 9. The second collection tank 3 is equipped with one set of vibrators 21, which is located near the left side of the second collection tank 3.

[0050] Since the separation of hydrogen peroxide solution requires strong vibration, vibrators 21 are linearly set along the moving path to ensure that the hydrogen peroxide solution is basically emptied. Finally, a set of vibrators 21 is set in the second collection tank 3 to assist in high-pressure rinsing while reducing water retention on the wheat, thus saving costs.

[0051] Example 3: Based on the above examples, a specific structure for a hydrogen peroxide tank 1 is provided;

[0052] A hydrogen peroxide controller 13 is installed on the right side of the hydrogen peroxide pool 1. The hydrogen peroxide controller 13 consists of a sensor, a PLC controller, a liquid pump and a storage tank.

[0053] The concentration and volume of hydrogen peroxide solution in hydrogen peroxide tank 1 are detected in real time by sensors. The PLC controller receives the feedback and controls the liquid pump to replenish the concentration and volume of hydrogen peroxide solution in hydrogen peroxide tank 1.

[0054] Example 4: Based on the above examples, a specific structure for fixing the mesh plate 11 and telescopic mesh plate 12 is provided.

[0055] Fixed outer frame rods 111 are provided on both sides of the fixed mesh plate 11, and telescopic outer frame rods 121 are provided at both ends of the telescopic mesh plate 12. The fixed outer frame rods 111 and the telescopic outer frame rods 121 are both in close contact with the inner wall of the outer baffle 4. A sliding groove 123 is provided on the outer side of the telescopic outer frame rod 121, and a sliding rod 112 is provided on the outer side of the fixed outer frame rod 111. The sliding rod 112 is slidably connected in the sliding groove 123.

[0056] Preferably, the telescopic outer frame rod 121 is connected to the inner wall of the outer conveyor belt 10 through the elastic connecting part 122. The telescopic mesh plate 12 is made of metal mesh, and one end of the metal mesh is fixedly connected to the inner wall of the outer conveyor belt 10. This hinged connection method can improve the sealing between the telescopic mesh plate 12 and the inner wall of the outer baffle 4.

[0057] This design ensures that when the fixed mesh plate 11 and the telescopic mesh plate 12 slide relative to each other, no wheat will pass through the fixed mesh plate 11 and the telescopic mesh plate 12, and the telescopic and transmission are stable.

[0058] Example 5: Based on the above examples, a specific high-pressure flushing assembly 6 structure is provided;

[0059] The high-pressure flushing assembly 6 includes a water storage tank 61 located in front of the second collection tank 3. A high-pressure water pump 62 is located above the water storage tank 61. A flushing nozzle 63 is fixedly installed on the outer side of the outer baffle 4. The flushing nozzle 63 is connected to the outlet of the high-pressure water pump 62. The outlet of the flushing nozzle 63 is obliquely downward and located below the inner conveyor line 9 and inside the outer conveyor belt 10.

[0060] Clean water from the water storage tank 61 is pumped into the rinsing nozzles 63 by the high-pressure water pump 62. Several rinsing nozzles 63 spray obliquely toward the wheat to rinse it. The nozzles of the rinsing nozzles 63 do not exceed the inner wall of the outer baffle 4 and will not interfere with the fixed mesh plate 11 and the telescopic mesh plate 12.

[0061] Example 5: Based on the above examples, a specific structure of centrifugal dehydration component 7 and negative pressure conveying component 8 is provided;

[0062] The centrifugal dehydration assembly 7 includes a centrifuge 71 located on the left side of the bottom tank. A drive motor 72 is located at the bottom of the centrifuge 71. A centrifugal inner cylinder 73 is rotatably installed inside the centrifuge 71. The centrifugal inner cylinder 73 is connected to the output end of the drive motor 72. The bottom of the centrifugal inner cylinder 73 is tapered.

[0063] The negative pressure conveying assembly 8 includes a negative pressure hopper 81 fixedly installed on the top of the centrifuge 71. A negative pressure fan 82 is fixedly installed in the center of the top of the negative pressure hopper 81. Two sets of feed pipes 83 are provided on the top of the negative pressure hopper 81, and the two sets of feed pipes 83 are located on both sides of the negative pressure fan 82. A material port is opened on the outer side of each of the two outer baffles 4, and the material port is located at the second recessed part 43. The two sets of feed pipes 83 are connected to the two material ports respectively, and each set of feed pipes 83 is equipped with... There is a feed solenoid valve 84, and a three-way solenoid valve 85 is installed at the bottom outlet of the negative pressure hopper 81. One port of the three-way solenoid valve 85 is connected to the inlet of the centrifuge 71, and the other port is equipped with a discharge pipe 86. A suction pipe 87 is installed at the top of the negative pressure hopper 81. The lower half of the suction pipe 87 is inserted into the centrifuge inner cylinder 73, and the center line of the lower half of the suction pipe 87 coincides with the rotation axis of the centrifuge inner cylinder 73. A suction solenoid valve 88 is installed on the suction pipe 87.

[0064] Material conveying process:

[0065] Feeding: The external conveyor belt 10 transports wheat to the second sinking section 43, causing the wheat to pile up and stay at the feed inlet for a long time. At this time, the negative pressure fan 82 starts, the suction solenoid valve 88 and the three-way solenoid valve 85 close, and the feed solenoid valve 84 opens. Negative pressure is generated in the negative pressure hopper 81 and the feed pipe 83, which sucks the wheat at the second sinking section 43 into the negative pressure hopper 81. The space in the negative pressure hopper 81 is large, and the wheat piles up in the negative pressure hopper 81 under its own gravity. After the equipment has been running for a period of time, the negative pressure fan 82 is turned off, and the three-way solenoid valve 85 is opened. The three-way solenoid valve 85 connects the negative pressure hopper 81 to the inlet of the centrifuge 71. The wheat in the negative pressure hopper 81 automatically falls into the centrifuge inner cylinder 73 under gravity, completing the feeding.

[0066] Centrifugal dehydration: The drive motor 72 drives the centrifuge inner cylinder 73 to rotate at high speed, dehydrating the wheat inside;

[0067] Discharge: After dehydration, restart the negative pressure fan 82, close the three-way solenoid valve 85, close the feed solenoid valve 84, and open the suction solenoid valve 88. Negative pressure is generated in the negative pressure hopper 81 and the suction pipe 87. The suction pipe 87 draws the dehydrated wheat from the centrifuge inner cylinder 73 into the negative pressure hopper 81. The space in the negative pressure hopper 81 is relatively large, and the wheat accumulates in the negative pressure hopper 81 under its own gravity. Because the bottom of the centrifuge inner cylinder 73 is conical, the wheat will flow into the bottom of the suction pipe 87 in a concentrated manner, and the wheat can be completely sucked out. After the suction is completed, the negative pressure fan 82 is turned off, and the three-way solenoid valve 85 is opened. The three-way solenoid valve 85 connects the negative pressure hopper 81 with the discharge pipe 86, and the wheat is discharged through the discharge pipe 86 under gravity.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
