[0002] In the fields of agricultural production and food processing, the treatment of seeds or other granular articles is a key process. Due to various influences such as weather, the surface of seeds is prone to infection and carry germs, and there are stains on the seed surface with poor color and luster, which not only affect the appearance, germination rate and survival rate of seeds, but also may spread diseases, resulting in crop yield reduction or quality decline.

[0003] Currently, in the food processing field, the water washing and disinfection method for large materials (such as vegetables) is relatively mature. For example, the raw materials are placed on a conveyor belt, moved and washed under the action of water flow, and at the same time, the raw materials are pressed into the water by a wave wheel arranged above to achieve all-round cleaning. However, this technology is not applicable to small particles such as seeds. First, the seeds are small in volume and light in weight, and will float up when moving in water, dispersing to various areas, unable to ensure the full cleaning and disinfection of seeds, and there are differences in the cleaning time, resulting in inconsistent colors of seeds and affecting the appearance of seeds. And the existing methods of manual or mechanical stirring water washing, circulating dry grinding, etc. for treating seeds will result in obvious stain-removing effect, uneven color, and unable to achieve sufficient disinfection and sterilization, and will also affect the quality of seeds. Summary of the Invention

[0007] On the basis of the above solution, the bed dryer includes a water pumping device and a drying bed body. The bed board of the drying bed body is a perforated plate, and the air extraction port of the water pumping device is located below the drying bed body.

[0008] On the basis of the above solution, the bed dryer further includes a process regulating valve for regulating the air extraction flow rate.

[0009] On the basis of the above solution, the liquid medicine and water treatment device includes a medicine preparation tank, a medicine storage tank, a filtered medicine tank, a clean water tank, and a filtered water tank. The liquid outlet of the medicine preparation tank is connected to the liquid inlet of the liquid medicine cleaning machine through a first pipeline. The medicine storage tank is connected to the medicine preparation tank and the filtered medicine tank through a second pipeline and a third pipeline respectively. The liquid inlet of the filtered medicine tank is connected to the liquid discharge port of the liquid medicine cleaning machine through a fourth pipeline. The clean water tank and the filtered water tank are connected to the water inlet and the water discharge port of the clean water cleaning machine through a fifth pipeline and a sixth pipeline respectively.

[0010] Based on the above system, the present invention also provides a disinfection and stain removal method using sodium hypochlorite solution, including the following steps:

[0011] Step S1, quantitatively add the material to be processed into the hanging basket through a belt scale;

[0012] Step S2, transport the hanging basket to the liquid medicine cleaning machine for cleaning through a driving device along a preset circular track, and drain it on the first draining table after cleaning;

[0013] Step S3, after draining is completed, transport the hanging basket to the clean water cleaning machine for cleaning along the circular track, and drain it on the second draining table after cleaning;

[0029] The invention will be further described below in conjunction with specific embodiments.

[0030] In order to improve the automation degree of seed treatment and the cleaning and drying efficiency, the present invention proposes a disinfection and stain removal system using sodium hypochlorite solution, which mainly includes:

[0031] Circular track: Supports the hanging basket to move continuously along the track;

[0032] A hanging basket, used for loading seeds, capable of moving along a track and lifting and lowering;

[0033] A driving device, used for driving the hanging basket to travel along the track and realizing the lifting and lowering of the hanging basket;

[0034] A raw material bin, storing seeds to be processed, with a belt scale for metering and conveying materials arranged below;

[0035] A liquid medicine and water treatment device, providing sodium hypochlorite solution and clean water to the liquid medicine cleaning machine and the clean water cleaning machine respectively;

[0036] A process treatment unit, including: a liquid medicine cleaning machine, using sodium hypochlorite solution to disinfect and remove stains from seeds;

[0037] A first draining table, used for initially draining the liquid medicine on the surface of the seeds;

[0038] A clean water cleaning machine, using clean water to remove the residual liquid medicine and impurities on the surface of the seeds;

[0039] A second draining table, further draining the water on the surface of the seeds;

[0040] A bed dryer, used for drying the seeds.

[0041] Among them, both the liquid medicine cleaning machine and the clean water cleaning machine are equipped with air pump devices for generating bubbles to assist in cleaning; the bed dryer accelerates the draining process of the seeds through a water pumping device, significantly shortening the drying time.

[0042] As Figure 1 and Figure 2 shown, the system includes a circular track 20, a hanging basket 3, a driving device 4 for driving the hanging basket to travel along the circular track and enabling the hanging basket to lift and lower, a liquid medicine and water treatment device, and a raw material bin 1, a liquid medicine cleaning machine 5, a first draining table 6, a clean water cleaning machine 7, a second draining table 8, and a bed dryer 9 arranged in sequence from the upstream to the downstream of the process.

[0043] A belt scale 2 is arranged below the raw material bin. The hanging basket 3 moves along the circular track 20 under the action of the driving device 4 and can move up and down. When the hanging basket moves to a suitable position, the seeds in the raw material bin 1 are conveyed into the hanging basket 3 through the belt scale 2. The hanging basket moves downward under the action of the driving device, and the seeds on the belt scale are moved into the hanging basket without the hanging basket contacting the belt scale, ensuring that the hanging basket does not have mechanical contact with other devices to generate additional friction or damage, and at the same time avoiding affecting the normal movement of the hanging basket.

[0044] Specifically, the annular track is designed as a closed loop, which can support the continuous circular movement of the hanging basket along the annular track. The system also includes an annular track truss 21, which supports the annular track and provides a stable running path for the hanging basket.

[0045] As Figure 3 shown, to prevent seed leakage, the hanging basket 3 is covered with sieve plate holes 31 around its perimeter and at the bottom door. The diameter of the sieve plate holes is smaller than the minimum size of the seed particles, while the sieve plate holes can ensure unobstructed passage of the liquid medicine and clean water during the cleaning process. The bottom of the hanging basket is provided with a fully open discharge door 32, which can reduce the impact force during discharging, play a buffering role, and avoid damaging the drying machine body. Moreover, the fully open discharge door adopts an embedded structure, and through a tight fit design, it can ensure no residue during discharging. At the same time, to prevent seeds and liquid medicine from splashing out from above the hanging basket, a movable anti-overflow cover plate is provided at the top of the hanging basket.

[0046] Preferably, the driving device is an electric hoist. According to this application, the belt scale feeds 300 - 500 kilograms of materials into each hanging basket. The hanging basket needs to move along the annular track and move up and down to complete the cleaning, draining, and drying processes. The electric hoist drives the steel wire rope or chain through a motor to achieve the vertical lifting of the hanging basket, and combines with a remote control or button to achieve precise control of the horizontal movement. This design can meet the requirement of the flexible switching of the hanging basket between the feeding unit, the cleaning unit, and the drying unit. Moreover, the electric hoist has a high load capacity (usually up to several hundred kilograms to several tons), which is fully adapted to the scenario of the hanging basket loading 300 - 500 kilograms of seeds. In addition, the structure of the electric hoist is simple and easy to maintain, reducing the cost and complexity of long-term use, and enabling the equipment to operate smoothly and still maintain reliable performance under high-frequency use.

[0047] According to this application, devices such as a pneumatic hoist, a hydraulic lift, a linear motor, a ball screw lift, or a chain conveyor can also be used to achieve the movement and lifting of the hanging basket.

[0048] Under the action of the belt scale, the driving device, and the annular track, automatic loading and transportation of seeds are realized, automated operation is achieved, manual intervention is simplified, and the entire processing process becomes more efficient and accurate.

[0049] After the feeding is completed, the hanging basket sequentially places the seeds into the liquid medicine washing machine 5 and the clean water washing machine 7 in the cleaning unit for cleaning. The sodium hypochlorite solution in the liquid medicine washing machine is used to disinfect and remove stains from the seeds, and then the sodium hypochlorite solution on the surface of the seeds is washed off in the clean water washing machine.

[0050] The air pump device includes a high-pressure air pump 51, a high-pressure main air pipe 52, and high-pressure branch air pipes 53. The high-pressure air pump is used to provide sufficient pressure and flow rate, capable of meeting the large-capacity cleaning requirements of 300 - 500 kg in the hanging basket, ensuring the cleaning efficiency and quality. The high-pressure air pump transports gas to the cleaning pool through the high-pressure main air pipe and high-pressure branch air pipes. The high-pressure main air pipe extends to the bottom of the cleaning machine. There are multiple high-pressure branch air pipes, which are respectively connected to the high-pressure main air pipe and evenly distributed at the bottom of the cleaning machine. Air outlet holes are provided on the high-pressure branch air pipes. The air outlet holes are evenly distributed at the bottom of the cleaning pool, enabling the pressure gas to form a large number of fine bubbles 57, covering all parts of the pool, thus ensuring the full cleaning of the seeds.

[0051] The liquid medicine cleaning machine and the clean water cleaning machine have the same structure but use different solutions. For example, Figure 4 and Figure 5 As shown, a suitable concentration of sodium hypochlorite solution is injected into the liquid medicine cleaning machine 5 and the liquid level is maintained at a certain height with the overflow port 54. During cleaning, the excess liquid is discharged through the overflow port to maintain the liquid level in the cleaning pool within a stable range.

[0052] Preferably, the high-pressure air pump is a high-pressure vortex air pump, which can provide a large flow rate and high-pressure air flow under low energy consumption, is suitable for large-scale seed cleaning scenarios, and has durability, capable of providing long-term continuous operation.

[0053] This application can also use devices such as roots blowers, centrifugal air pumps, reciprocating air pumps, and screw air pumps to provide high-pressure air flow.

[0054] According to one embodiment, when in use, the high-pressure branch air pipes are set to 16, each with a diameter of 40 mm. The high-pressure branch air pipes are evenly distributed at the bottom of the cleaning pool. There are 17 evenly distributed round holes on each branch air pipe to ensure that the pressure gas is evenly distributed in the pool through the air holes, thus ensuring the consistency of the seed cleaning quality.

[0055] Preferably, the aperture of the air outlet hole is designed to be gradually changed along the direction of the high-pressure branch air pipe. The aperture of the air outlet hole is small at the end close to the high-pressure main air pipe and large at the end far from the high-pressure main air pipe. Since the gas pressure decreases with the increase of distance, such a design can ensure the uniform release of gas pressure, thereby improving the uniformity of the bubble distribution in the cleaning pool and the consistency of the cleaning effect.

[0056] The working principle of the liquid medicine cleaning machine and the clean water cleaning machine mainly uses high-pressure bubbles as the power to achieve the cleaning, stain removal, and disinfection of seeds through the action of solution conduction. The specific working principle is as follows:

[0057] Put the items to be cleaned into the cleaning pool of the cleaning machine and start the cleaning machine;

[0058] The cleaning machine injects compressed air into the sodium hypochlorite solution through an air pump device, generating a large number of tiny high-pressure bubbles. These high-pressure bubbles rapidly rise in the solution, forming a bubble jet;

[0059] During the rising process, the high-pressure bubbles collide with the surface of the seeds, generating an impact force. This impact force can effectively remove dirt, impurities, and microorganisms on the surface of the seeds, playing a role in stain removal, disinfection, and sterilization;

[0060] The rising and bursting of the high-pressure bubbles will cause the agitation and swirling of the sodium hypochlorite solution flow, further enhancing the cleaning effect. The agitation of the sodium hypochlorite solution flow can make the dirt and impurities on the surface of the seeds easier to be removed;

[0061] Set an appropriate cleaning time according to the degree of contamination and cleaning requirements of the items;

[0062] During the cleaning process, the sewage overflowing from the cleaning pool is discharged through the overflow tank. The sewage contains the dirt, impurities, and microorganisms washed off;

[0063] After disinfecting and removing stains from the seeds using the liquid medicine cleaning machine, rinse the items with clean water in the clean water cleaning machine to remove the remaining dirt and liquid medicine on the seeds. The contaminated and unusable solution is discharged from the cleaning machine through the drain port 55.

[0064] When cleaning the seeds, the seeds are successively immersed in the liquid medicine cleaning machine and the clean water cleaning machine through the hanging basket. The sieve plate holes on the hanging basket ensure unobstructed passage of the compressed gas and the liquid medicine. The seeds are in a suspended state in the hanging basket, ensuring thorough cleaning of the seeds. Specifically, the bubble pressure passes through the sieve plate holes through the liquid medicine as a carrier, causing the liquid medicine to drive the seeds to tumble and wash, and the pressure is uniform everywhere in the hanging basket, ensuring consistent and gentle scouring intensity of the seeds, maximizing the protection of the seeds from damage, and ensuring the consistency of the seed decolorization, disinfection, and stain removal quality after water washing.

[0065] The first draining platform and the second draining platform are respectively arranged behind the liquid medicine cleaning machine and the clean water cleaning machine to remove the excess water on the surface after cleaning. This not only reduces the residue of the liquid medicine, ensures cleaner seed cleaning, but also reduces the burden of subsequent processes and improves the overall cleaning efficiency.

[0066] Specifically, after the cleaning and draining are completed, the hanging basket moves above the bed-type dryer, and the fully open discharge door at the bottom of the hanging basket is opened to completely discharge the materials onto the drying bed body 93. It should be noted that since the materials are piled up in the shape of a small hill on the drying bed body after unloading, it is not conducive to consistent water discharge everywhere when the pumping device conducts air extraction and water pumping. Therefore, it is advisable to level the materials on the drying bed body. If leveling by hand is time-consuming and laborious and there are safety hazards, the leveling is carried out by setting the spreading mechanism 34 using the walking of the hanging basket itself, which is highly efficient and has few hazards.

[0067] like Figure 3 and Figure 4 As shown, a material spreading mechanism 34 and a fixed part 33 are provided on the side of the hanging basket away from the movement direction. The material spreading mechanism includes a rotating shaft 341, a swing rod 342 and a material spreading part 343. The swing rod is rotatably connected to the hanging basket through the rotating shaft, the fixed part is fixedly connected to the hanging basket, and the swing rod is detachably connected to the fixed part. After unloading, the material spreading part spreads the seeds on the drying bed through the movement of the hanging basket.

[0068] After the discharge is completed, the swing rod of the material spreading mechanism is disassembled from the fixed part, so that the material spreading mechanism is in an active state, and the swing rod is rotated downward along the rotating shaft until it can no longer rotate. At this time, the material spreading mechanism is at an acute angle to the vertical direction. When the hanging basket moves along the track, the bottom end of the swing part maintains a certain height with the drying bed, and this height can be achieved by adjusting the position of the hanging basket according to demand. Through the movement of the hanging basket, the seeds can be evenly spread on the drying bed by the material spreading part.

[0069] Preferably, the dryer uses a drying burner to convert the heat energy generated by burning fuel into hot air that can be used for drying to provide heat for the seeds.

[0070] Specifically, the bed plate above the drying bed is a sieve plate. Under the action of the pumping device 92, the moisture of the seeds falls and is discharged through the sieve plate, and the flow rate is adjusted by the process regulating valve 91. The diameter of the sieve holes on the sieve plate is smaller than the minimum size of the seeds to prevent seed leakage. At the same time, the hot air generated by the dryer is evenly distributed to the entire bed through the sieve plate, making the temperature more uniform, promoting the convection circulation of the air, and further improving the drying efficiency.

[0071] Specifically, the pumping device may be a pumping fan, a vacuum pump, a gravity drain tank or the like.

[0072] like Figure 6 As shown, according to one of the embodiments, in actual use, a process regulating valve 91 is arranged under each drying bed 93. After the drying bed is covered with seeds, the valve is opened, and the water drained by the water-extracting fan is turned on to be discharged to the outside through the water-extracting fan. When there is no water discharged by the fan, the fan is stopped and the valve is closed, and the dryer is started.

[0073] Because the time required for cleaning and draining is less, but the drying time is very long, the steps of cleaning and draining often need to wait for the drying step, which results in low overall operating efficiency. Although setting multiple bed dryers can improve the efficiency to a certain extent, it will cause a significant increase in the system construction cost and operating cost. By setting a pumping device and actively pumping air, the moisture between the seeds on the drying bed quickly drains and falls, and is discharged by the pumping device. This not only greatly saves the system construction cost but also improves the system operating efficiency. It can increase the dryer efficiency by 30%, save half of the drying time, and effectively improve the overall production capacity.

[0074] As Figure 7 shown, the liquid medicine and water treatment device includes a medicine preparation tank 10, which includes a medicine storage tank 11, a filtered medicine tank 12, a clean water tank 13, and a filtered water tank 14. The liquid outlet of the medicine preparation tank is connected to the liquid inlet 56 of the liquid medicine cleaning machine through a first pipeline. The medicine storage tank is connected to the medicine preparation tank and the filtered medicine tank through a second pipeline and a third pipeline respectively. The liquid inlet of the filtered medicine tank is connected to the liquid discharge port 55 of the liquid medicine cleaning machine through a fourth pipeline. The clean water tank and the filtered water tank are connected to the water inlet and the drain outlet of the clean water cleaning machine through a fifth pipeline and a sixth pipeline respectively. The medicine preparation tank is used to prepare a 2% sodium hypochlorite solution. The contaminated solutions used in the liquid medicine cleaning machine and the clean water cleaning machine are transported to the liquid medicine and water treatment device for treatment and then reused, which can realize the reuse of liquid medicine and water and save resources.

[0075] Based on the above system, the present invention provides a disinfection and stain removal method using sodium hypochlorite solution, including the following steps:

[0076] Step S1, quantitatively add the material to be processed into the hanging basket through a belt scale;

[0077] Step S2, transport the hanging basket to the liquid medicine cleaning machine for cleaning along a preset circular track through a driving device, and drain it on the first draining platform after cleaning;

[0078] Step S3, after draining is completed, transport the hanging basket to the clean water cleaning machine for cleaning along the circular track, and drain it on the second draining platform after cleaning;

[0079] Step S4, after step S3 is completed, transport the hanging basket above the drying bed, open the bottom door of the hanging basket to unload the material, and spread out the material for drying until the moisture content reaches the standard.

[0080] In the step S1, there is a gap between the belt scale and the hanging basket during feeding, and they are arranged at an angle. The seeds have an upward acceleration, and the seeds are thrown into the hanging basket under the action of the belt scale. In steps S2 and S3, the time can be set for timed cleaning and timed water drainage in the cleaning machine and the water drainage table. When drying the seeds in step S3, first use a pumping device to suck out the moisture of the material, and then use a dryer to dry the material.

[0081] The concentration of sodium hypochlorite solution used in the liquid medicine cleaning machine is 2%. The 2% concentration can ensure that the sodium hypochlorite solution can effectively remove stubborn stains on the surface of the seeds, can effectively kill the germs carried on the surface of the seeds, and reduce the risk of seed-borne diseases. Moreover, the sodium hypochlorite solution with a concentration of 2% avoids corrosion or damage to the seeds caused by too high a concentration. At the same time, the main products after the decomposition of sodium hypochlorite are harmless salts and water, and will not cause pollution to the environment.

[0082] According to one embodiment, immerse the material hanging basket 3 in the solution of the liquid medicine cleaning machine 5 at a certain height, set the cleaning duration to 2 - 3 minutes, turn on the air pump device. After the cleaning is completed, turn the hanging basket 3 to the clean water cleaning machine 7 for rinsing. The structure of the clean water machine 7 is the same as that of the liquid medicine cleaning machine 5, and there is an air pump device at the bottom that can generate uniformly pressured bubbles. The water injected into the clean water cleaning machine 7 is clean water, set the rinsing duration to 1 - 3 minutes. After the end, immediately enter the water drainage table for 2 minutes of water drainage, and then immediately send it to the bed-type dryer. Start the pumping device and the dryer to remove the moisture of the seeds to be detected. After the water content meets the standard, discharge and package the seeds for storage in the warehouse.

[0083] According to actual verification, the seeds have a good effect after being cleaned in the liquid medicine cleaning machine for 2 - 3 minutes. Therefore, in order to improve efficiency, the time does not need to be set too long. If the seeds are seriously contaminated, the time can be extended to 5 minutes.

[0084] Through the above method, it ensures the same input and output of the treated seeds. And due to the consistency of pressure everywhere in the liquid medicine, the intensity of bubble flushing and tumbling is consistent, ensuring the consistency of the seed color and disinfection effect. Since it is liquid flushing, it ensures that the seeds are not damaged, and the liquid medicine parameters controlled for each batch of seeds are the same, and various control times are the same, thus ensuring the quality consistency of the whole batch of seeds.

[0085] According to the present application, the seeds to be processed are added into the raw material bin. There is a belt scale below the raw material bin. The belt scale quantitatively adds 300-500 kg of seeds into the hanging basket each time. Then, the hanging basket is transported to the liquid medicine cleaning machine by an electric hoist along the circular track for positioning and cleaning, and then transported to the water draining table by the electric hoist along the circular track for draining. Then, it is transported to the clean water cleaning machine by the electric hoist along the circular track for positioning and timed cleaning, and then transported to the clean water draining table by the electric hoist along the circular track for draining. Then, the hanging basket is transported to the fixed position of the bed dryer by the electric hoist along the circular track, and the four discharging doors at the bottom of the hanging basket are opened to discharge materials in sequence. After discharging, the hanging basket returns to the position of the raw material bin again, and 300-500 kg of materials are added by the belt scale to complete one cycle. One cycle takes about 10-15 minutes, and the water washing treatment capacity is 3-5 tons per hour. Compared with the existing treatment device, the production efficiency has been greatly improved.

[0086] As needed, each group of liquid medicine cleaning machines and clean water cleaning machines can be configured with 4-8 hanging baskets, and each hanging basket is configured with an electric hoist along the circular track to complete continuous cyclic use. By increasing the number of liquid medicine cleaning machines, clean water cleaning machines, and the corresponding number of hanging baskets, water draining tables and bed dryers, the processing capacity can be correspondingly increased to meet the production requirements of different scales and ensure the supply of seeds.

[0087] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.

[0088] Although the specific implementation manners of the present invention are described above, it is not a limitation to the protection scope of the present invention. Those skilled in the art should understand that based on the technical solution of the present invention, various modifications or deformations that can be made without creative efforts by those skilled in the art are still within the protection scope of the present invention.
