Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food processing equipment, in particular to a drum-type vegetable stirring and cleaning device. BACKGROUND

[0002] After being picked, vegetables have a large amount of soil, dust and a small amount of pesticide residues attached to their surfaces. Cleaning is a necessary process before vegetable processing and consumption. Drum-type cleaning devices are widely used in large-scale vegetable cleaning scenarios due to their large cleaning capacity and simple operation.

[0003] In the prior art, such as patent No. CN211960845U "Vegetable stirring and cleaning device", the core structure includes a fixed outer cavity (outer cylinder) and a rotatable drum arranged in the outer cavity. Water holes are formed in the drum wall. The drum is driven to rotate by a driving mechanism, and the vegetables in the drum are cleaned by rolling and colliding. The specific structural features of the device are as follows: the outer cavity is cylindrical and fixed on the frame, and cannot rotate, and only relies on the one-way rotation of the drum to drive the internal vegetables; although a simple stirring protrusion is provided in the drum, the stirring protrusion is integrated with the drum and rotates in the same direction as the drum, and the essence still relies on the single rotation of the drum to provide cleaning power.

[0004] However, in actual application, the above-mentioned existing device has the following problems: the outer cavity is fixed, the drum and the internal stirring structure rotate in the same direction, and the movement trajectory of the vegetables in the drum is relatively single; the outer layer of vegetables is subjected to the friction force and centrifugal force of the inner wall of the drum, and the rolling amplitude is large, and the cleaning effect is good; but the vegetables located at the center position of the drum are easily wrapped by the outer layer of vegetables, and their movement is severely restricted, the rolling amplitude is small, the contact with the cleaning water is insufficient, and it is difficult to form effective collision and friction with the inner wall of the drum and the stirring protrusion. This leads to the fact that the soil and impurities on the surface of the vegetables at the center position cannot be completely removed, the cleaning effect is poor, and some vegetables need to be cleaned twice, which not only reduces the cleaning efficiency, but also increases the consumption of water resources and processing cost; especially for root vegetables (such as carrots and potatoes) or vegetables with thick leaves (such as cabbage and lettuce), the cleaning blind area problem at the center position is more prominent, which affects the quality of vegetable processing.

DETAILED DESCRIPTION

[0021] It is easy to understand that, according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole of the present application or as the limitation or restriction of the technical scheme of the present application.

[0022] The specific embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 - Figure 4 In the present embodiment, a drum-type vegetable stirring and cleaning device is proposed, which comprises a frame 1, an outer cylinder 2 and an inner cylinder 3.

[0024] The upper end of the frame 1 is rotatably connected with the upper rods 101 and the lower rods 102 through pin shafts, and the number of the upper rods 101 and the lower rods 102 is both two, which are symmetrically distributed from top to bottom based on the upper end of the frame 1. The front end of the upper rods 101 and the lower rods 102 is rotatably connected with the swing frames 103 through pin shafts, and the front end of the swing frames 103 is stably installed with the swing covers 104 through screws, and the outer cylinder 2 is installed on the inner side of the swing covers 104 in a vertical posture through screws. The two sides of the frame 1 are rotatably connected with the electric telescopic rods 105 through pin shafts, and the telescopic part of the upper end of the electric telescopic rods 105 is rotatably connected with the middle part of the lower rods 102 through pin shafts.

[0025] The upper and lower ends of the outer cylinder 2 are welded with water inlet 201 and water outlet 202 through the swing cover 104. The outer ends of the water inlet 201 and the water outlet 202 are respectively provided with a switch valve. This design allows the vegetables to be washed by the water inlet 201 and the water outlet 202. The inner cylinder 3 is rotatably connected to the middle part of the outer cylinder 2 through the shaft, and the axis of the inner cylinder 3 coincides with the axis of the outer cylinder 2. The upper end of the inner cylinder 3 is provided with a feed inlet 301, and the upper end of the feed inlet 301 is provided with a sealing cover 302 through interference connection. The inner wall of the inner cylinder 3 is uniformly provided with a plurality of water holes 303. This design ensures that the washing water between the outer cylinder 2 and the inner cylinder 3 can flow smoothly, and the impurities can also be easily discharged. The inner wall of the inner cylinder 3 is also bonded with a plurality of convex patterns 304. These convex patterns 304 are used to stir the washing water, so that the washing water forms a flow in the inner cylinder 3. The bottom of the swing cover 104 is provided with a stirring motor 4 through a screw. The transmission shaft of the stirring motor 4 is connected to the stirring shaft 401 through a key. The stirring shaft 401 extends upward through the shaft and is rotatably connected to the central axis of the inner cylinder 3. The outer curved surface of the stirring shaft 401 is also connected to a plurality of stirring blades 402 through a key. These stirring blades can stir the vegetables in the inner cylinder 3 to make them roll and flow.

[0026] The upper end of the outer wall of the outer cylinder 2 is provided with a driving motor 5 through a bolt support. The transmission shaft of the driving motor 5 is connected to the gear 501 through a key. The inner side of the gear 501 is connected to the gear ring 502, and the gear ring 502 is installed on the upper end of the outer wall of the inner cylinder 3 through a screw. This design allows the inner cylinder 3 to rotate through the meshing of the gear 501 and the gear ring 502. In order to protect the gear ring 502, the upper end of the inner cylinder 3 and the upper end of the swing cover 104 are respectively bonded with a first cover 503 and a second cover 504 to shield the gear ring 502.

[0027] Please continue to read Figure 1 Figure 4 When using this embodiment, first open the sealing cover 302 of the feed inlet 301, and put the vegetables to be washed into the inner cylinder 3. Then, the washing water is discharged into the inner cylinder 3 through the water inlet 201. When the washing water is discharged, the stirring motor 4 is controlled to be turned on. The stirring motor 4 drives the stirring shaft 401 to rotate, and then drives the stirring blades 402 to rotate and stir in the inner cylinder 3, so that the vegetables in the inner cylinder 3 are in full contact with the washing water, realizing the washing.

[0028] ​When the stirring blade 402 rotates and stirs, the driving motor 5 is controlled to rotate. The driving motor 5 drives the gear 501 to rotate, and then drives the gear ring 502 to rotate in the opposite direction relative to the stirring blade 402. The reverse rotation of the gear ring 502 drives the inner cylinder 3 to rotate in the opposite direction, and then drives the convex strip 304 to rotate in the opposite direction, forming a bidirectional stirring power. The reverse rotation of the convex strip 304 stirs the cleaning water in the inner cylinder 3 in the opposite direction, so that the vegetables in the inner cylinder 3 are stirred, the cleaning friction of the vegetables is enhanced, and thus the soil and impurities on the surface of the vegetables are completely removed, and the cleaning efficiency is improved.

[0029] When the vegetables are cleaned, the rotation of the stirring blade 402 is stopped, and the cleaning water and impurities are discharged through the water outlet 202. During the discharging of the cleaning water and impurities, the rotating inner cylinder 3 drives the vegetables to rotate, and the residual cleaning water on the surface of the vegetables is quickly spun dry under the action of the rotating centrifugal force, so that the draining time of a single batch of vegetables is shortened, and the cleaning efficiency is further improved.

[0030] When the vegetables are spun dry, the electric telescopic rod 105 is controlled to extend. The extension of the electric telescopic rod 105 drives the lower rod 102 to swing upward, and then cooperates with the upper rod 101 to drive the swing cover 104 to swing. The swing of the swing cover 104 synchronously drives the outer cylinder 2 to swing and tilt outward, and then drives the inlet 301 at the upper end of the inner cylinder 3 to tilt. At this time, the vegetables in the inner cylinder 3 after cleaning can be taken out through the inlet 301.

[0031] Example 1: Leafy vegetable (spinach) cleaning example Preparation Equipment inspection: confirm that the parts of the device are stably connected, the upper rod 101 and the lower rod 102 of the rack 1 and the pin shaft of the swing frame 103 rotate flexibly, the extension function of the electric telescopic rod 105 is normal; check the interference connection sealing property of the sealing cover 302 and the inlet 301 of the inner cylinder 3 to ensure that there is no looseness and leakage; verify that the wiring of the stirring motor 4 and the driving motor 5 is normal, the gear 501 and the gear ring 502 are well engaged, the first cover 503 and the second cover 504 are well blocked to the gear ring 502, and there is no foreign matter interference.

[0032] Material preparation: select 20 kg of fresh spinach, remove obviously rotten and withered leaves, and remove entangled weeds for standby.

[0033] Auxiliary preparation: prepare clean tap water as cleaning water, ensure that the opening and closing of the water inlet 201 and the water outlet 202 are smooth, and place a wastewater collection container under the water outlet 202.

[0034] Cleaning operation steps Feeding process: Hold the sealing cover 302 on the upper end of the inner cylinder 3 with both hands, pull it out along the axial direction with force (use the disassembly characteristics of interference fit), and then evenly pour the pretreated 20 kg of spinach into the inner cylinder 3, ensuring that the spinach does not exceed the upper limit of the volume of the inner cylinder 3 (to avoid affecting the stirring effect); then press the sealing cover 302 against the feeding port 301 with force to achieve interference sealing, preventing water from splashing out during cleaning.

[0035] Water injection process: Open the switch valve of the water inlet 201, and inject clean tap water into the inner cylinder 3. During the water injection process, observe the water level in the inner cylinder 3. When the water level reaches 2 / 3 of the volume of the inner cylinder 3 (to ensure that the spinach can be completely immersed in water), close the switch valve of the water inlet 201 and stop water injection.

[0036] Two-way stirring and cleaning process: Turn on the power supply, set the stirring motor 4 speed to 40 r / min and the drive motor 5 speed to 30 r / min through the control panel; start the stirring motor 4 and the drive motor 5 at the same time, the stirring motor 4 drives the stirring shaft 401 and the stirring blades 402 on the surface to rotate clockwise, longitudinally stirring the spinach in the center area of the inner cylinder 3, making the spinach separate from the accumulated state; the drive motor 5 drives the gear 501 to rotate, and through the meshing transmission of the gear 501 and the gear ring 502, it drives the inner cylinder 3 to rotate counterclockwise, the inner wall of the inner cylinder 3 rotates in the opposite direction with the inner cylinder, and the convex pattern 304 on the inner wall stirs the cleaning water to form a spiral flow, which forms a two-way action with the stirring force of the stirring blades 402, making the spinach roll and rub against each other in the water flow. During the cleaning process, the dirt, residual pesticides and other impurities on the surface of the spinach enter the gap between the outer cylinder 2 and the inner cylinder 3 through the water-permeable holes 303, achieving the separation of impurities and vegetables, and the cleaning process continues for 8 minutes.

[0037] Drainage and drying process: After the cleaning time is over, keep the drive motor 5 running, open the switch valve of the water outlet 202, and the waste water containing impurities between the outer cylinder 2 and the inner cylinder 3 is discharged into the collection container through the water outlet 202; at the same time, the inner cylinder 3 continues to rotate counterclockwise, and the centrifugal force is used to quickly spin off the water remaining on the surface of the spinach, which is discharged through the water-permeable holes 303. The spin-drying time is set to 2 minutes, until no obvious water flow flows out of the water outlet 202, and the drive motor 5 and the water outlet 202 valve are closed.

[0038] Discharging process: Start the electric telescopic rod 105, control its telescopic end to extend upward, drive the lower rod 102 to swing upward around the pin shaft on the upper end of the rack 1, and the lower rod 102 and the upper rod 101 work together to drive the swing frame 103 and the swing cover 104 to swing outward, so that the outer cylinder 2 tilts to 30° with the swing cover 104, and the feeding port 301 of the inner cylinder 3 tilts downward at the same time; pull out the sealing cover 302, and the inclined inner cylinder 3 makes the spinach slide out of the feeding port 301 under the action of gravity and fall into the pre-placed storage basket, completing the discharging.

[0039] Implementation effect After cleaning, the removal rate of surface sand on spinach reached 98.5%, there was no obvious pesticide residue (in line with GB2763-2021 National Food Safety Standard), the leaf was intact without damage, the surface moisture content was less than 15%, compared with the traditional cleaning method, the draining time was shortened by 60%, and the cleaning efficiency was improved by 45%.

[0040] Example 2: Cleaning of root and stem vegetables (potatoes) Preparation Equipment inspection: focus on checking the adhesion firmness of the convex 304 on the inner wall of the inner cylinder 3 to avoid the convex 304 falling off due to collision with potatoes during cleaning; confirm the reliable key connection of the stirring blade 402 and the stirring shaft 401, and the coaxiality error of the stirring shaft 401 and the central axis of the inner cylinder 3 is ≤0.5mm; verify that the output torque of the driving motor 5 meets the requirements of the inner cylinder 3 driving the weight to rotate, and the gear 501 and the gear ring 502 have no wear and jam.

[0041] Material preparation: select 30kg of fresh potatoes, remove obvious large soil clumps on the surface, remove rotten and germinated individuals, and the weight of each potato is 100-150g.

[0042] Auxiliary preparation: configure cleaning solution containing food-grade cleaning agent (concentration 0.1%), ensure that the inlet 201 pipeline is unobstructed, and the filter screen of the outlet 202 is not blocked (to prevent potato debris from accumulating).

[0043] Cleaning operation steps Feeding process: disassemble the sealing cover 302 of the inner cylinder 3, slowly put 30kg of pretreated potatoes into the inner cylinder 3, avoid the potatoes from concentrating and hitting the inner wall of the inner cylinder 3, causing damage to the convex 304; after the feeding is completed, install the sealing cover 302 in place to ensure that the feeding port 301 is sealed well.

[0044] Water injection process: open the inlet valve 201, inject the prepared cleaning solution containing cleaning agent into the inner cylinder 3, the water injection amount is 3 / 4 of the volume of the inner cylinder 3 (to ensure that the potatoes are fully contacted with the cleaning solution during stirring), and close the inlet valve 201.

[0045] Two-way stirring cleaning process: set the stirring motor 4 speed to 50r / min and the driving motor 5 speed to 35r / min, start the two motors; the stirring blade 402 rotates counterclockwise, deeply into the potato accumulation layer, and turns the potatoes in the central area upward to avoid local accumulation; the inner cylinder 3 rotates clockwise, the convex 304 on the inner wall hits and scrapes the surface of the potatoes, and cooperates with the scouring force of the water flow to strip off the stubborn soil and skin impurities on the surface of the potatoes; the shear force formed by the two-way rotation makes the potatoes rub against each other, further improving the cleaning effect, and the cleaning is continued for 12 minutes.

[0046] Drain and spin-dry process: turn off the stirring motor 4, keep the driving motor 5 running, open the water outlet 202 valve to drain the impure cleaning liquid; then close the water outlet 202, re-open the water inlet 201 to inject clean tap water, start the stirring motor 4 (speed 30 r / min) for 2 minutes of rinsing; after rinsing, turn off the stirring motor 4, open the water outlet 202 to drain the rinsing water, and the inner cylinder 3 continues to rotate for 3 minutes to spin-dry the surface moisture of the potatoes by centrifugal force, and turn off the driving motor 5.

[0047] Discharging process: start the electric telescopic rod 105, control the outer cylinder 2 to tilt to an angle of 35°, so that the inner cylinder 3 feeding port 301 is tilted downward, pull out the sealing cover 302, and the potatoes orderly slide out under the action of gravity. Due to the guiding effect of the inner wall relief 304 of the inner cylinder 3, there is no jamming and congestion phenomenon, and the potatoes smoothly fall into the storage device.

[0048] Implementation effect The removal rate of soil on the surface of the cleaned potatoes reaches 99%, the skin is not scratched or damaged, and there is no cleaning agent residue (in line with food safety standards). The single-batch cleaning time is only 17 minutes, which is 8 times more efficient than manual cleaning. After spin-drying, the water content on the surface of the potatoes is less than 10%, so there is no need for additional airing before entering the subsequent processing link (such as peeling and cutting), effectively shortening the production process.

[0049] Example 3: Mixed vegetable (carrot + lettuce) cleaning implementation example Implementation preparation Equipment inspection: comprehensively inspect all transmission components of the device to ensure that the screw connection between the swing cover 104 and the outer cylinder 2 is fastened, the telescopic stroke of the electric telescopic rod 105 is normal (the maximum extension length meets the requirement of tilting the outer cylinder 2 by 40°), and the start-stop response speed of the stirring motor 4 and the driving motor 5 is tested to ensure that the two-way rotation is coordinated and synchronized.

[0050] Material preparation: select 15 kg of carrots (single weight 80-120 g) and 10 kg of lettuce, remove the root-like material from the carrots, and separate the leaves from the lettuce. After pretreatment, mix them together for use.

[0051] Auxiliary preparation: prepare clean tap water, and install a filter screen with a pore size of 2 mm at the water outlet 202 to prevent the lettuce leaves from blocking the drainage channel.

[0052] Cleaning operation steps Feeding process: open the inner cylinder 3 sealing cover 302, and evenly pour the mixture of 15 kg of carrots and 10 kg of lettuce into the inner cylinder 3 to avoid the carrots from pressing the lettuce leaves; install the sealing cover 302 and ensure that it is sealed in place.

[0053] Water injection process: open the water inlet 201 valve, inject clean tap water to 2 / 3 of the volume of the inner cylinder 3, and close the valve to ensure that the mixed vegetables are completely immersed.

[0054] The bidirectional stirring and cleaning process is as follows: the rotation speed of the stirring motor 4 is set to 35 r / min, the rotation speed of the driving motor 5 is set to 28 r / min, and the double motors are started; the stirring blade 402 rotates clockwise, gently stirs the lettuce leaves, avoids damage to the leaves, and drives the carrots to roll in the water flow; the inner cylinder 3 rotates counterclockwise, the convex lines 304 stir the water flow to form a vortex, so that the surface of the carrot is fully rubbed with the water flow and the inner cylinder wall, the lettuce leaves are stretched in the water flow, the surface impurities are discharged with the water flow through the water-permeable holes 303, and the cleaning process is continued for 10 minutes.

[0055] The draining and spinning process is as follows: the driving motor 5 is kept running, the water outlet 202 valve is opened to discharge waste water, the centrifugal force of the inner cylinder 3 makes the water on the surface of the carrot and the lettuce quickly spin out, the lettuce leaves are prevented from being entangled because the stirring blade 402 stops rotating, the spinning time is set to 2.5 minutes, and the driving motor 5 and the water outlet 202 valve are closed.

[0056] The discharging process is as follows: the electric telescopic rod 105 is started to make the outer cylinder 2 tilt at an angle of 32°, the sealing cover 302 is pulled out, and the mixed vegetables are orderly discharged from the feeding port 301, the carrot and the lettuce are not obviously entangled, and the subsequent sorting can be directly performed, and the cleaning process is completed.

[0057] Implementation effect After cleaning, the dirt on the surface of the carrot is completely removed, the lettuce leaves are clean, free of stains and damage, and the mixed cleaning does not cause mutual contamination or damage of the vegetables; the single-batch cleaning efficiency is 25 kg / 12.5 minutes, which saves 30% of time compared with separate cleaning, and the water resource consumption is only 50% of that of the traditional cleaning equipment, which has high efficiency and energy saving and environmental protection.
