Description

Technical Field

[0001] This invention belongs to the field of vegetable processing technology, specifically a multi-stage cleaning and impurity removal device and its processing method for vegetable processing. Background Technology

[0002] A vegetable washing device is used to remove dirt, pesticide residues, and bacteria from the surface of vegetables. It is commonly used in food processing, the catering industry, and home kitchens. This device uses a combination of efficient water flow and mechanical force to ensure vegetables are thoroughly cleaned in a short time. Generally, a vegetable washing device consists of several parts, including a washing tank, a spray system, a conveyor belt, and a filter. Clean water is filled into the washing tank, and the spray system evenly sprays water to remove impurities and dirt from the vegetable surface.

[0003] Conventional vegetable washing equipment mainly relies on spray systems and washing tanks to achieve the vegetable washing process. In actual use, this type of washing equipment relies solely on soaking and spraying, which is insufficient to remove residual dirt from vegetables. Furthermore, after washing, the vegetables are drained only through the drain holes on the conveyor belt, leaving a large amount of water on the surface of the vegetables, which affects their quality and fails to achieve effective cleaning.

[0004] Furthermore, conventional vegetable washing devices use filters to remove wastewater and impurities. However, during prolonged use, the filter screen becomes clogged due to its pore size, which affects the actual filtration effect and necessitates improvement. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-stage cleaning and impurity removal device and method for vegetable processing, 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: a multi-stage cleaning and impurity removal device for vegetable processing, comprising a base, a transfer component installed at the center of the top of the base, a pre-washing tank, a soaking and washing component, and a dehydration component sequentially installed in a clockwise circumferential pattern on the outer side of the base, a frame movably installed at the bottom of the transfer component, an inner cleaning tank fixedly installed at the bottom of the frame, an outer cleaning tank movably sleeved on the outer side of the inner cleaning tank, the inner cleaning tank rotating relative to the outer cleaning tank, a fine-tuning component installed on one side of the outer cleaning tank, a drive shaft fixedly installed at the center of the bottom of the outer cleaning tank, an annular groove opened on the side of the outer cleaning tank near the top, an adjusting rod fixedly installed on the side of the inner cleaning tank near the top, the annular groove and the adjusting rod being movably engaged, and the filter holes opened on the outer cleaning tank and the inner cleaning tank having the same position and number.

[0007] Before washing the vegetables, place them inside the inner washing tank and ensure that there is no water inside the soaking and dehydrating components. Then, use the transfer component to raise the outer and inner washing tanks to their highest positions and place them directly above the pre-washing tank.

[0008] As a further technical solution of the present invention, the transfer component includes a cam divider, the bottom end of which is connected to the middle of the top of the base, the output end of which is fixedly equipped with a main cylinder, and the single rotation angle of the cam divider is 120 degrees.

[0009] As a further technical solution of the present invention, a transfer frame is fixedly installed at the output end of the main cylinder, the transfer frame is movably connected to the frame, and the frame rotates relative to the transfer frame.

[0010] As a further technical solution of the present invention, a water inlet pipe is embedded inside the frame, the top end of the water inlet pipe is connected to an external water pipe, and the bottom end of the water inlet pipe is fixedly connected to a nozzle.

[0011] When the outer and inner cleaning tanks, which are loaded with water to be cleaned, are moved to the top of the pre-washing tank, the main cylinder can be opened and controlled to shorten, which will drive the outer and inner cleaning tanks to move down as a whole until they are completely moved into the interior of the pre-washing tank. Then, the external water pipe can be opened to bring out external clean water through the water inlet pipe and the nozzle, and spray the top of the vegetables to clean them, thus completing the pre-washing operation.

[0012] After the pre-wash is completed, the main cylinder is extended to lift the outer and inner cleaning tanks as a whole until they are completely moved out of the pre-wash tank. Then, the cam divider is activated to rotate the outer and inner cleaning tanks 120 degrees clockwise until they are moved above the soaking wash assembly. The downward movement is repeated to completely move the outer and inner cleaning tanks into the soaking wash assembly, and the soaking wash assembly completes the soaking wash process.

[0013] After soaking and washing, repeat the above transfer operation to move the outer and inner cleaning tanks into the dehydration assembly, and complete the dehydration operation through the dehydration assembly. Repeat the above process to complete the automated continuous cleaning process.

[0014] By utilizing the coordination between the pre-wash tank and the transfer assembly, as well as the soaking and washing assembly and the dehydration assembly, the transfer assembly enables the rapid transfer of vegetables between the pre-wash tank, the soaking and washing assembly, and the dehydration assembly. This allows the vegetables to undergo the three processes of pre-washing, soaking and washing, and dehydration, and the entire process is completed continuously. This allows the vegetables to quickly complete the washing and dehydration process, significantly shortening the washing time, increasing the degree of automation, and improving the washing efficiency.

[0015] As a further technical solution of the present invention, the soaking washing assembly includes a soaking tank, and a first motor is mounted on the bottom end of the soaking tank via a mounting bracket. The output shaft of the first motor passes through the bottom end of the soaking tank and is fixedly connected to a mixing rack located inside the soaking tank.

[0016] When the outer and inner cleaning tanks are fully inside the soaking tank, clean water can continue to be output through the nozzles. At the same time, the first motor can be turned on to drive the mixing rack to rotate. The mixing rack can then turbulent the clean water inside the soaking tank and cause the vegetables inside the inner cleaning tank to tumble and roll. The tumbling of the vegetables further cleans them, while soaking removes additional impurities.

[0017] As a further technical solution of the present invention, the dehydration assembly includes a dehydration tank, and a second motor is mounted on the bottom end of the dehydration tank via a mounting bracket. The output shaft of the second motor passes through the bottom end of the dehydration tank and is fixedly connected to a transmission sleeve located inside the dehydration tank.

[0018] As a further technical solution of the present invention, when the outer cleaning tank and the inner cleaning tank are both lowered into the interior of the dehydration tank, the bottom end of the drive shaft is movably engaged with the drive sleeve.

[0019] When the outer and inner cleaning tanks, after cleaning, are fully inserted into the dehydration tank, the bottom end of the drive shaft can engage with the drive sleeve, thus completing the power transmission. At this point, the second motor can be turned on to drive the drive sleeve to rotate, and the outer and inner cleaning tanks will rotate synchronously through the drive shaft. This generates centrifugal force to throw out the clean water and impurities inside the inner cleaning tank, completing the auxiliary dehydration and drying process.

[0020] By utilizing the combined action of the transfer and dehydration components, the device can quickly dehydrate and dry vegetables after washing. The entire process is completed quickly, effectively reducing residual moisture on the surface of the vegetables, preventing them from shrinking, reducing the problem of moisture residue caused by traditional drain holes, and improving the overall washing quality.

[0021] As a further technical solution of the present invention, the fine-tuning component includes an extension frame, a third motor is mounted on the inner side of the extension frame, a drive gear is mounted on the output end of the third motor, and a driven gear frame is meshed with one side of the drive gear.

[0022] As a further technical solution of the present invention, one side of the driven gear frame is fixed to the adjusting rod. When the driving gear rotates, it drives the driven gear frame to rotate circumferentially and drives the adjusting rod to slide relative to the annular groove, thereby completing the rotation of the inner cleaning tank relative to the outer cleaning tank.

[0023] During the dehydration process of vegetables, the third motor can be turned on to drive the drive gear to rotate. When the drive gear rotates, it drives the driven gear frame to swing. At this time, the driven gear frame rotates relative to the center of the outer washing tank, and at the same time drives the adjusting rod to slide relative to the annular groove. Finally, it drives the inner washing tank to rotate relative to the outer washing tank. At this time, the overlapping filter holes on the outer and inner washing tanks change accordingly until the filter holes are completely aligned and no longer overlap. At this time, the pore diameter of the filter holes is at its maximum value. With the rapid rotation of the outer and inner washing tanks, the impurities inside and in the filter holes can be thrown out, completing the rapid dehydration and self-cleaning process.

[0024] By utilizing the coordination between the fine-tuning component and the inner and outer cleaning tanks, as well as its coordination with the dehydration component, the device can achieve water drainage and impurity removal simultaneously by changing the pore size of the filter holes during dehydration and drying. At the same time, it can achieve self-cleaning of impurities inside the filter holes. The entire process is completed automatically, which can effectively reduce clogging and improve cleaning efficiency.

[0025] A method for processing vegetables using a multi-stage cleaning and impurity removal device includes the following steps:

[0026] S1: Before washing, the vegetables are introduced into the inner washing tank, and the filter holes of the outer washing tank and the inner washing tank are kept in a staggered state. First, the outer washing tank and the inner washing tank are placed inside the pre-washing tank through the transfer component, and the external water pipe is turned on to export clean water through the nozzle and act on the vegetables inside the inner washing tank to complete the pre-spray washing.

[0027] S2: After the pre-spraying and cleaning is completed, the outer and inner cleaning tanks are transferred to the inside of the soaking and washing unit through the transfer component, and water is injected again through the nozzle. At the same time, the first motor is turned on to drive the mixing rack to rotate, which turbulents the water flow and makes the vegetables roll, thus completing the further soaking and cleaning.

[0028] S3: After cleaning, the outer and inner cleaning tanks are transferred to the dehydration unit via the transfer component. At the same time, the extension frame is activated, driving the driven gear frame to rotate circumferentially and causing the inner cleaning tank to rotate relative to the outer cleaning tank. This prevents the filter holes from overlapping and transforms them into their maximum aperture. Simultaneously, the second motor is activated, driving the outer and inner cleaning tanks to rotate synchronously via the transmission sleeve, completing the dehydration and impurity removal. Impurities inside the filter holes are also thrown out. After dehydration, the vegetables are removed, and the above process is repeated to complete the continuous automatic cleaning process.

[0029] The beneficial effects of this invention are as follows:

[0030] (1) This invention utilizes the cooperation between the pre-wash tank and the transfer component, as well as the soaking and washing component and the dehydration component. Through the function of the transfer component, vegetables are quickly transferred between the pre-wash tank, the soaking and washing component, and the dehydration component. This allows vegetables to undergo the three processes of pre-washing, soaking and washing, and dehydration, and the whole process is completed continuously. This allows vegetables to quickly complete the washing and dehydration process, significantly shortens the washing time, improves the degree of automation, and improves the washing efficiency.

[0031] (2) By utilizing the cooperation between the transfer component and the dehydration component, the present invention enables the device to quickly dehydrate and dry the vegetables after washing them. The whole process is completed quickly, which can effectively reduce the residual moisture on the surface of the vegetables, prevent the vegetables from becoming less, reduce the problem of moisture residue caused by traditional drain holes, and improve the overall cleaning quality.

[0032] (3) By utilizing the cooperation between the fine-tuning component and the inner and outer cleaning tanks, and the cooperation between the component and the dehydration component, the device can achieve the removal of impurities while draining water during dehydration and drying by changing the pore size of the filter holes. At the same time, it can achieve the self-cleaning of impurities in the filter holes. The whole process is completed automatically, which can effectively reduce clogging and improve cleaning efficiency. Attached Figure Description

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.

[0043] like Figures 1 to 8 As shown in the embodiment of the present invention, a multi-stage cleaning and impurity removal device for vegetable processing includes a base 1. A transfer component 3 is installed at the middle of the top of the base 1. A pre-wash tank 2, a soaking and washing component 4, and a dehydration component 5 are sequentially installed in a clockwise circumferential pattern on the outer side of the base 1. A frame 6 is movably installed at the bottom of the transfer component 3. An inner cleaning tank 10 is fixedly installed at the bottom of the frame 6. An outer cleaning tank 9 is movably sleeved on the outer side of the inner cleaning tank 10. The inner cleaning tank 10 rotates relative to the outer cleaning tank 9. A fine-tuning component 14 is installed on one side of the outer cleaning tank 9. A drive shaft 11 is fixedly installed at the middle of the bottom of the outer cleaning tank 9. An annular groove 12 is opened on the side of the outer cleaning tank 9 near the top. An adjusting rod 13 is fixedly installed on the side of the inner cleaning tank 10 near the top. The annular groove 12 and the adjusting rod 13 are movably engaged. The positions and numbers of filter holes opened on the outer cleaning tank 9 and the inner cleaning tank 10 are the same.

[0044] Before washing the vegetables, place them inside the inner washing tank 10 and ensure that there is no water inside the soaking washing component 4 and the dehydration component 5. Then, use the transfer component 3 to lift the outer washing tank 9 and the inner washing tank 10 to the highest position and place them directly above the pre-washing tank 2.

[0045] like Figure 1 and Figure 2 as well as Figure 5As shown, the transfer assembly 3 includes a cam divider 301. The bottom end of the cam divider 301 is connected to the middle of the top of the base 1. A main cylinder 302 is fixedly installed at the output end of the cam divider 301. The single rotation angle of the cam divider 301 is 120 degrees. A transfer frame 303 is fixedly installed at the output end of the main cylinder 302. The transfer frame 303 is movably connected to the frame 6. The frame 6 rotates relative to the transfer frame 303. A water inlet pipe 7 is embedded inside the frame 6. The top end of the water inlet pipe 7 is connected to an external water pipe. The bottom end of the water inlet pipe 7 is fixedly connected to a nozzle 8.

[0046] Example: When the outer washing tank 9 and inner washing tank 10, which are loaded with vegetables to be washed, are moved to the top of the pre-washing tank 2, the main cylinder 302 can be opened and controlled to shorten, and the outer washing tank 9 and inner washing tank 10 are moved down as a whole until they are completely moved into the interior of the pre-washing tank 2. Then, the external water pipe can be opened to bring out external clean water through the water inlet pipe 7 and the nozzle 8, and spray the top of the vegetables to clean them, thus completing the pre-washing operation.

[0047] After the pre-wash is completed, the main cylinder 302 is extended to raise the outer cleaning tank 9 and the inner cleaning tank 10 as a whole until they are completely moved out of the interior of the pre-wash tank 2. Then, the cam divider 301 is activated to rotate the outer cleaning tank 9 and the inner cleaning tank 10 clockwise by 120 degrees until they are moved above the soaking wash assembly 4. The downward movement is repeated to completely move the outer cleaning tank 9 and the inner cleaning tank 10 into the interior of the soaking wash assembly 4, and the soaking wash process is completed through the soaking wash assembly 4.

[0048] After soaking and washing, repeat the above transfer operation to move the outer cleaning tank 9 and the inner cleaning tank 10 into the interior of the dehydration component 5, and complete the dehydration operation through the dehydration component 5. Repeat the above process to complete the automated continuous cleaning process.

[0049] By utilizing the cooperation between the pre-wash tank 2 and the transfer component 3, as well as the soaking and washing component 4 and the dehydration component 5, the vegetables can be quickly transferred between the pre-wash tank 2, the soaking and washing component 4, and the dehydration component 5 through the function of the transfer component 3. This allows the vegetables to undergo the three processes of pre-washing, soaking and washing, and dehydration, and the entire process is completed continuously. This allows the vegetables to quickly complete the washing and dehydration process, significantly shortens the washing time, improves the degree of automation, and increases the washing efficiency.

[0050] like Figure 1 and Figure 3 As shown, the soaking and washing assembly 4 includes a soaking tank 401. A first motor 402 is mounted on the bottom end of the soaking tank 401 via a mounting bracket. The output shaft of the first motor 402 passes through the bottom end of the soaking tank 401 and is fixedly connected to a mixing rack 403 located inside the soaking tank 401.

[0051] When the outer cleaning tank 9 and the inner cleaning tank 10 are fully inside the soaking tank 401, clean water can continue to be output through the nozzle 8. At the same time, the first motor 402 is turned on to drive the mixing rack 403 to rotate. The mixing rack 403 can turbulent the clean water inside the soaking tank 401 and cause the vegetables inside the inner cleaning tank 10 to turn and roll. The vegetables are further cleaned by turning, and additional impurities are washed away by soaking.

[0052] like Figure 1 and Figure 4 As shown, the dehydration assembly 5 includes a dehydration tank 501. A second motor 502 is mounted on the bottom of the dehydration tank 501 via a mounting bracket. The output shaft of the second motor 502 passes through the bottom of the dehydration tank 501 and is fixedly connected to a transmission sleeve 503 located inside the dehydration tank 501. When the outer cleaning tank 9 and the inner cleaning tank 10 are both lowered into the interior of the dehydration tank 501, the bottom of the transmission shaft 11 is movably engaged with the transmission sleeve 503.

[0053] Example: When the outer cleaning tank 9 and the inner cleaning tank 10, after cleaning, are both inside the dehydration tank 501, the bottom end of the drive shaft 11 can be engaged with the drive sleeve 503, thus completing the power transmission. At this time, the second motor 502 can be turned on to drive the drive sleeve 503 to rotate, and the outer cleaning tank 9 and the inner cleaning tank 10 can be driven to rotate synchronously through the drive shaft 11. The centrifugal force generated will throw out the clean water and impurities inside the inner cleaning tank 10, thus completing the auxiliary dehydration and drying process.

[0054] By utilizing the combined action of the transfer component 3 and the dehydration component 5, the device can quickly dehydrate and dry the vegetables after washing them. The entire process is completed quickly, which can effectively reduce the residual moisture on the surface of the vegetables, prevent the vegetables from shrinking, reduce the problem of moisture residue caused by traditional drain holes, and improve the overall washing quality.

[0055] like Figure 1 and Figure 6 as well as Figure 7 As shown, the fine-tuning component 14 includes an extension frame 141. A third motor 142 is mounted on the inner side of the extension frame 141. A drive gear 143 is mounted on the output end of the third motor 142. A driven gear frame 144 is meshed with one side of the drive gear 143. One side of the driven gear frame 144 is fixed to the adjusting rod 13. When the drive gear 143 rotates, it drives the driven gear frame 144 to rotate circumferentially and drives the adjusting rod 13 to slide relative to the annular groove 12, thus completing the rotation of the inner cleaning tank 10 relative to the outer cleaning tank 9.

[0056] Example: During the dehydration of vegetables, the third motor 142 can be turned on to drive the drive gear 143 to rotate. When the drive gear 143 rotates, it can drive the driven gear frame 144 to swing. At this time, the driven gear frame 144 can rotate relative to the center of the outer washing tank 9, and at the same time drive the adjusting rod 13 to slide relative to the annular groove 12. Finally, it drives the inner washing tank 10 to rotate relative to the outer washing tank 9. At this time, the overlapping filter holes on the outer washing tank 9 and the inner washing tank 10 change accordingly until the filter holes are completely aligned and no longer overlapped. At this time, the pore diameter of the filter holes is at its maximum value. With the rapid rotation of the outer washing tank 9 and the inner washing tank 10, the impurities inside and the impurities in the filter holes can be thrown out, completing the rapid dehydration and self-cleaning process.

[0057] By utilizing the cooperation between the fine-tuning component 14 and the inner cleaning tank 10 and the outer cleaning tank 9, and by utilizing its cooperation with the dewatering component 5, the device can achieve the purpose of draining water and removing impurities at the same time by changing the pore size of the filter holes during dewatering and drying. At the same time, it can achieve self-cleaning of impurities in the filter holes. The whole process is completed automatically, which can effectively reduce clogging and improve cleaning efficiency.

[0058] A method for processing vegetables using a multi-stage cleaning and impurity removal device includes the following steps:

[0059] S1: Before washing, the vegetables are introduced into the inner washing tank 10, and the filter holes of the outer washing tank 9 and the inner washing tank 10 are kept in a misaligned state. First, the outer washing tank 9 and the inner washing tank 10 are placed inside the pre-washing tank 2 through the transfer component 3, and the external water pipe is turned on to export clean water through the nozzle 8 and act on the vegetables inside the inner washing tank 10 to complete the pre-spray washing.

[0060] S2: After the pre-spraying and cleaning is completed, the outer cleaning tank 9 and the inner cleaning tank 10 are transferred to the inside of the soaking and washing component 4 through the transfer component 3, and water is injected again through the nozzle 8. At the same time, the first motor 402 is turned on to drive the mixing rack 403 to rotate, which turbulents the water flow and makes the vegetables roll, thus completing the further soaking and cleaning.

[0061] S3: After cleaning is completed, the outer cleaning tank 9 and the inner cleaning tank 10 are transferred to the inside of the dehydration assembly 5 by the transfer component 3. At the same time, the extension frame 141 is opened, driving the driven gear frame 144 to rotate circumferentially, and causing the inner cleaning tank 10 to rotate relative to the outer cleaning tank 9, so that the filter holes no longer overlap and the filter holes are transformed into the maximum aperture. At the same time, the second motor 502 is turned on, and the outer cleaning tank 9 and the inner cleaning tank 10 are driven to rotate synchronously through the transmission sleeve 503 to complete the dehydration and removal of impurities. At the same time, the impurities in the filter holes are thrown out. After dehydration is completed, the vegetables are taken out and the above process is repeated to complete the continuous automatic cleaning process.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

S3: After cleaning, the outer cleaning tank (9) and the inner cleaning tank (10) are transferred to the inside of the dehydration unit (5) by the transfer component (3). At the same time, the extension frame (141) is opened, and the driven gear frame (144) is driven to rotate circumferentially, and the inner cleaning tank (10) is driven to rotate relative to the outer cleaning tank (9), so that the filter holes no longer overlap and the filter holes are transformed into the maximum aperture. At the same time, the second motor (502) is turned on, and the outer cleaning tank (9) and the inner cleaning tank (10) are driven to rotate synchronously through the transmission sleeve (503) to complete the dehydration and removal of impurities. At the same time, the impurities in the filter holes are thrown out. After dehydration is completed, the vegetables are taken out and the above process is repeated to complete the continuous automatic cleaning process.
