Description

Technical Field

[0001] This invention relates to the field of bamboo leaf processing technology, and more specifically to a bamboo leaf conveying device for disinfecting bamboo leaves. Background Technology

[0002] Reed leaves primarily come from the leaves of *Indocalamus* or other large bamboo species. Reed leaves are typically quite large, oblong or lanceolate in shape. They are thick, flexible, and not easily broken, making them particularly suitable for wrapping zongzi (sticky rice dumplings), imparting a unique aroma and shape to the dumplings. In the reed leaf processing, sterilization is a crucial step in ensuring food safety. To improve efficiency and hygiene standards, specialized conveying equipment is used to process the leaves. This equipment is an indispensable component in achieving an efficient, uniform, and controllable sterilization process.

[0003] When bamboo leaves are used as packaging for zongzi (sticky rice dumplings), their natural color, fragrance, and soft texture need to be preserved to the greatest extent during disinfection. Therefore, the common method is to soak the bamboo leaves in disinfectant followed by rinsing. This method can achieve efficient disinfection and thorough removal of residues from the surface of the bamboo leaves. However, the surface of bamboo leaves has a velvety structure and natural folds along the width of the leaf. When soaking in disinfectant, the bamboo leaves tend to overlap each other. Combined with the velvety surface and folds, this affects the contact effect between the bamboo leaves and the disinfectant, resulting in blind spots during disinfection and cross-contamination during subsequent transportation. Summary of the Invention

[0004] This invention proposes a bamboo leaf conveying device for disinfecting bamboo leaves, comprising:

[0005] The conveyor has multiple sets of parallel conveying channels arranged along the width direction. Each conveying channel has a disinfection zone, a cleaning zone and a drying zone arranged in sequence along the conveying direction of the bamboo leaves, and the conveying direction is perpendicular to the width direction.

[0006] A first conveyor is installed within the disinfection zone, and the disinfection zone contains disinfectant water.

[0007] The second conveyor is located in the cleaning area and can rinse the surface of the bamboo leaves with disinfectant.

[0008] The third and fourth conveyors are located in the drying zone and are capable of drying residual water on the surface of the bamboo leaves;

[0009] The two adjacent conveying channels are separated by a partition. The length direction of the bamboo leaves in each conveying channel is parallel to the conveying direction, and only a single bamboo leaf is conveyed in the width direction of each conveying channel. The first conveyor includes a first conveyor belt and a first conveyor roller group with the same conveying speed for the bamboo leaves. The first conveyor belt is partially disposed in the disinfectant water. The first conveyor roller group includes a pair of conveyor rollers that press against the two sides of the bamboo leaves. The conveyor rollers are connected to an air supply pipe group and can deliver airflow to the surface of the bamboo leaves to form bubbles in the disinfectant water on the surface of the bamboo leaves.

[0010] Preferably, the conveying roller includes a contact ring and a roller body. The contact ring is fixedly fitted onto the outer side wall of the roller body, and multiple contact rings are arranged along the axial direction of the roller body. Each contact ring has a cyclically alternating contact portion and air guide portion on its circumferential surface. The surface of the contact portion is arc-shaped, and the surface of the air guide portion is flat. The contact portion protrudes from the air guide portion. Multiple contact rings are staggered in the circumferential direction along the axial direction, and the contact portion and air guide portion on the surfaces of adjacent contact rings are alternately distributed in the axial direction.

[0011] Preferably, each of the air guides is provided with an air guide port, and the roller body is provided with a connecting pipe corresponding to each air guide port, the connecting pipe being connected to the air guide port;

[0012] The conveying roller also includes a guide rod disposed inside the roller body. The guide rod is rotatably disposed relative to the roller body. The end of the guide rod is fixed to the inner wall of the conveyor. The roller body is driven to rotate by a driving device, and the linear velocity of the contact ring is equal to the conveying speed of the first conveyor belt.

[0013] Preferably, the air guide rod is provided with an air guide channel that communicates with the air supply pipe group. The air guide channel faces one side of the path through which the bamboo leaf passes. As the roller rotates outside the air guide rod, a plurality of the connecting pipes distributed in the circumferential direction circulate and communicate with the air guide channel, guiding the airflow to the surface of the bamboo leaf to form bubbles in the disinfectant water.

[0014] Preferably, the contact ring includes a silicone ring, and the number of the contact portions in the circumferential direction is equal to the number of the air guide portions and is equal to N, wherein 3≤N≤10.

[0015] Preferably, there are two first conveyor belts, which are symmetrically distributed on both sides of the first conveyor roller group along the conveying path. The upper ends of the two first conveyor belts are located above the liquid surface of the disinfectant, and the area between the first conveyor roller groups for the bamboo leaves to pass through is located below the liquid surface of the disinfectant.

[0016] Preferably, the second conveyor includes a second conveyor belt and a spray pipe assembly. The second conveyor belt is used to convey bamboo leaves in the cleaning area. The spray pipe assembly is connected to an external water supply device and is distributed on the upper and lower sides of the bamboo leaf conveying path. The spray pipe assembly is configured to guide water flow and spray it onto the upper and lower sides of the bamboo leaves.

[0017] Preferably, the drying zone includes a first drying zone and a second drying zone. The third conveyor is disposed in the first drying zone, and the fourth conveyor is disposed in the second drying zone. The third conveyor includes a third conveyor belt and a second conveyor roller group with the same conveying speed for the bamboo leaves. The third conveyor belt is configured as two groups and distributed on both sides of the second conveyor roller group on the conveying path. The third conveyor belt is used to convey the bamboo leaves in the first drying zone. The second conveyor roller group includes a pair of conveyor rollers that roll against the two sides of the bamboo leaves, and the conveyor rollers are connected to the air extraction pipe group so that the conveyor rollers can extract residual water from the surface of the bamboo leaves.

[0018] Preferably, the fourth conveyor includes a fourth conveyor belt and a drying air plate. The fourth conveyor belt is used to convey bamboo leaves in the second drying zone. The drying air plate is connected to an external air supply device through a drying air duct assembly. The drying air plate is distributed on the upper and lower sides of the bamboo leaf conveying path. The drying air plate is configured to direct airflow onto the upper and lower sides of the bamboo leaves.

[0019] Preferably, the drying air plate includes a converging plate and guide fins. The converging plate is connected to the drying air duct assembly, and the guide fins are disposed on the side of the converging plate facing the bamboo leaves. The guide fins guide the airflow in the converging plate obliquely to the surface of the bamboo leaves.

[0020] Compared with the prior art, the advantages of the present invention are as follows:

[0021] This invention separates the conveying equipment into a disinfection zone, a cleaning zone, and a drying zone. A pair of conveying rollers are installed in both the disinfection zone and the subsequent drying zone. When the conveying rollers in the disinfection zone contact the bamboo leaves, they unfold the wrinkles on the leaf surface and simultaneously direct airflow to the leaf surface, generating continuous and gentle physical friction and rinsing, thus improving the disinfection and rinsing effect. When the conveying rollers in the drying zone contact the bamboo leaves, they absorb residual water from the leaf surface and maintain a consistent water residue across the entire leaf surface, thereby accelerating the drying process and ensuring uniform drying.

[0031] To better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the present invention provides a bamboo leaf conveying device for disinfecting bamboo leaves, which completes the disinfection process of bamboo leaves during the conveying process. The device mainly includes a conveyor 10.

[0033] The conveyor 10 has multiple sets of parallel conveying channels arranged along its width. Each conveying channel has a disinfection zone 101, a cleaning zone 102, and a drying zone arranged sequentially along the conveying direction of the bamboo leaves. The conveying direction is perpendicular to the width direction. The first conveyor 20 is located in the disinfection zone 101, which contains disinfectant water 100. The second conveyor 30 is located in the cleaning zone 102 and can rinse the surface of the bamboo leaves with disinfectant water 100. The third conveyor 40 and the fourth conveyor 50 are both located in the drying zone and can dry the residual water on the surface of the bamboo leaves.

[0034] Generally, the bottom of the conveyor 10 is equipped with a stainless steel support 11 to maintain the structural stability of the conveyor 10. An isolation cover 12 is also provided above the cleaning area 102 and the drying area to reduce water splashing. Any two adjacent conveying channels are separated by a partition 13 so that the length direction of the bamboo leaves in each conveying channel is parallel to the conveying direction, and only a single bamboo leaf is conveyed in the width direction of each conveying channel. In this case, the bamboo leaves are conveyed in a single-leaf conveying manner to avoid the cleaning blind spots caused by the overlap between bamboo leaves. In this way, the disinfection and cleaning of the bamboo leaf surface will be more thorough when conveying bamboo leaves, and cross-contamination caused by undisinfected areas in blind spots can be avoided in subsequent conveying processes.

[0035] Furthermore, the drying zone includes a first drying zone 103 and a second drying zone 104. The disinfection zone 101, the washing zone 102, the first drying zone 103, and the second drying zone 104 are also arranged sequentially along the conveying direction of the bamboo leaves. A partition 13 is also provided between them. Through the separation of the partition 13, the disinfectant water 100, clean water, and drained residual water in each zone are separated by the partition 13. Each zone is equipped with an independent conveyor, which can avoid mutual exchange between different zones and avoid cross-contamination to a large extent. In addition, each zone is also equipped with a drainage pipe for independent drainage.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, the first conveyor 20 includes a first conveyor belt 21 and a first conveyor roller group 22 with the same conveying speed for the bamboo leaves. The first conveyor belt 21 is partially disposed in the disinfectant water 100. When the first conveyor belt 21 and the first conveyor roller group 22 convey the bamboo leaves at the same speed, the bamboo leaves will not be pulled due to the speed difference when they enter the first conveyor roller group 22 from the first conveyor belt 21. This can protect the bamboo leaves and prevent them from being pulled and broken.

[0037] In a preferred embodiment, two first conveyor belts 21 are provided and are symmetrically distributed on both sides of the first conveyor roller group 22 on the conveying path. The upper ends of the two first conveyor belts 21 are both above the liquid surface of the disinfectant water 100, and the area between the first conveyor roller groups 22 for the bamboo leaves to pass through is below the liquid surface of the disinfectant water 100.

[0038] During operation, bamboo leaves are placed on the first conveyor belt 21 from the feed side, with the length of the bamboo leaves parallel to the conveying direction of the first conveyor belt 21. As the first conveyor belt 21 conveys the bamboo leaves, they gradually enter below the surface of the disinfectant 100. The disinfectant 100 is used to disinfect the bamboo leaves. However, due to the natural folds and velvety structure on the surface of the bamboo leaves, the disinfectant 100 has difficulty penetrating into the folds. Therefore, even if a single leaf comes into contact with the disinfectant 100 without overlap, there will still be a disinfection blind spot. In order to disinfect the folded area, the bamboo leaves will pass through the first conveyor roller group 22 under the conveying of the first conveyor belt 21. The first conveyor roller group 22 flattens the folded structure on the surface of the bamboo leaves, so that the surface of the bamboo leaves comes into contact with the disinfectant 100 for disinfection.

[0039] In some embodiments, the disinfectant 100 uses a low-concentration chlorine dioxide solution. The low-concentration chlorine dioxide solution has a strong bactericidal ability (especially against mold, spores, and viruses), and it works quickly, leaves very little residue, and has almost no odor residue. Combined with subsequent water spraying, it can achieve efficient disinfection and thorough removal of residue.

[0040] like Figure 2 and Figure 3 As shown, the first conveying roller group 22 includes a pair of conveying rollers 60 that press against the two sides of the bamboo leaf. When the two conveying rollers 60, which are distributed vertically, come into contact with the bamboo leaf, the bamboo leaf is flattened by the rolling action of the conveying rollers 60, and the wrinkles on the surface of the bamboo leaf are opened up. At the same time, the conveying rollers 60 are connected to the air supply pipe group 14, which can output airflow to the surface of the bamboo leaf to form bubbles in the disinfectant water 100 on the surface of the bamboo leaf. During the flow of the bubbles on the surface of the bamboo leaf, they generate continuous and gentle physical friction and scouring on the surface of the bamboo leaf, which can more effectively loosen and remove impurities such as mud, sand and microbial biofilms attached to the wrinkles, back hairs and deep textures of the leaf. At the same time, the bubble disturbance can destroy the static boundary layer formed by the liquid on the surface of the bamboo leaf, accelerate the exchange of substances between the disinfectant water 100 and the surface of the leaf, and ensure that the disinfectant fully contacts all areas. Compared with mechanical (brush, etc.) washing methods, it can protect the surface structure of the bamboo leaf.

[0041] Thus, when the conveyor roller 60 comes into contact with the bamboo leaves, it not only flattens the leaves but also releases air bubbles onto the leaf surface. The mechanical action of these air bubbles on the leaf surface is gentle (compared to brushing or strong water jets), improving cleaning effectiveness while reducing physical damage to the leaf's fiber structure, better preserving its flexibility and integrity. This is especially important for bamboo leaves used in making zongzi (sticky rice dumplings), where the appearance of the leaves is crucial. Furthermore, the more impurities removed by air bubbles during the disinfection process, the easier it is to thoroughly remove residual disinfectant and impurities during the subsequent rinsing stage.

[0042] Furthermore, such as Figure 5 and Figure 6 As shown, the conveying roller 60 includes a contact ring 61 and a roller body 62. The contact ring 61 is fixedly fitted on the outer side wall of the roller body 62, and multiple contact rings are arranged along the axial direction of the roller body 62. Each contact ring 61 has a contact portion 611 and an air guide portion 612 that are arranged alternately on its circumferential surface.

[0043] The surface of the contact portion 611 is an arc surface, the surface of the air guide portion 612 is a plane, the contact portion 611 protrudes from the air guide portion 612, and multiple contact rings 61 are staggered in the circumferential direction along the axial direction, so that the contact portions 611 and air guide portions 612 on the surfaces of two adjacent contact rings 61 are alternately distributed in the axial direction.

[0044] Thus, when the contact ring 61 rolls against the surface of the bamboo leaf, in the circumferential direction (i.e., when the contact ring 61 rotates), the contact part 611 and the air guide part 612 circumferentially contact the surface of the bamboo leaf, and in the axial direction (i.e., the width direction of the bamboo leaf), the contact part 611 and the air guide part 612 also circumferentially contact the surface of the bamboo leaf. The contact part 611 can prevent slippage between the bamboo leaf and the contact ring 61, and at the same time ensure that when the contact ring 61 rotates, the air guide part 612 can always output air bubbles to the surface of the bamboo leaf. The air bubbles wash the surface of the bamboo leaf, promoting the disinfectant to contact and disinfect the bamboo leaf.

[0045] Furthermore, each air guide section 612 is provided with an air guide port 613, and the roller body 62 is provided with a connecting pipe 621 corresponding to each air guide port 613, and the connecting pipe 621 is connected to the air guide port 613.

[0046] Furthermore, the conveying roller 60 also includes a guide rod 63 disposed inside the roller body 62. The guide rod 63 is rotatably disposed relative to the roller body 62. The end of the guide rod 63 is fixed to the inner wall of the conveyor 10. The roller body 62 is driven to rotate by a drive device, and the linear velocity of the contact ring 61 is equal to the conveying speed of the first conveyor belt 21.

[0047] In some embodiments, the drive device may be driven by a combination of motor and transmission box to control the rotational speed of the roller 62 and coordinate with the conveying speed of the first conveyor belt 21 so that the conveying speed of the conveying roller 60 and the first conveyor belt 21 on the bamboo leaves is consistent. During driving, the air guide rod 63 is kept relatively fixed with the conveyor 10, and the roller 62 together with the contact ring 61 rotates outside the air guide rod 63. The bamboo leaves are conveyed by contacting the bamboo leaves through the contact ring 61.

[0048] Furthermore, the air guide rod 63 is provided with an air guide channel 631 that is connected to the air supply pipe group 14. The air guide channel 631 faces one side of the path through which the bamboo leaf passes. As the roller 62 rotates outside the air guide rod 63, multiple connecting pipes 621 distributed in the circumferential direction are cyclically connected to the air guide channel 631, and the airflow is guided to the surface of the bamboo leaf to form bubbles in the disinfectant water 100.

[0049] The air guide channel 631 can be configured as a channel with a fan-shaped or rectangular cross-section, such as... Figure 6 As shown, when the contact ring 61 and roller 62 rotate outside the air guide rod 63, the air guide channel 631 always faces the surface of the bamboo leaf. When a certain connecting pipe 621 rotates to connect with the air guide channel 631, the airflow passage is opened, and the airflow enters from the air supply pipe group 14 and passes through the air guide channel 631 and the connecting pipe 621 to the air guide port 613, guiding the airflow (bubbles) to the surface of the bamboo leaf. The air guide port 613 can be constructed in the shape of a trumpet. On the plane of the air guide part 612, the airflow (bubbles) can be guided to the front and rear sides to expand the contact area between the bubbles and the bamboo leaf, so that the contact part 611 and the contact part of the bamboo leaf can still be rinsed and disinfected by the bubbles.

[0050] In a preferred embodiment, the contact ring 61 can be a silicone ring. The silicone material can ensure that when in contact with the bamboo leaf, it also avoids damaging the surface structure of the bamboo leaf as much as possible. The number of contact parts 611 in the circumferential direction is equal to the number of air guide parts 612 and both are equal to N, where 3≤N≤10. It should be understood that the number of contact parts 611 and air guide parts 612 is not limited to N in this example, but when N is taken from the range of 3 to 10, the conveying effect of the contact parts 611 on the bamboo leaf and the effect of cooperating with the air guide parts 612 to convey air bubbles to the surface of the bamboo leaf are better.

[0051] like Figure 2 and Figure 3 As shown, the second conveyor 30 includes a second conveyor belt 31 and a spray pipe assembly 32. The second conveyor belt 31 is used to convey bamboo leaves in the cleaning zone 102. The spray pipe assembly 32 is connected to an external water supply device and is distributed on the upper and lower sides of the bamboo leaf conveying path. The spray pipe assembly 32 is configured to guide water flow and spray it onto the upper and lower sides of the bamboo leaves.

[0052] After the bamboo leaves are disinfected by contact with disinfectant 100 in the disinfection zone 101, disinfectant residue will remain on the surface of the bamboo leaves. In order to completely remove the residual disinfectant during subsequent transportation, clean water is sprayed onto the upper and lower sides of the bamboo leaves through the spray pipe group 32 in the cleaning zone 102 to clean and remove the residual disinfectant.

[0053] In a specific embodiment, the second conveyor belt 31 is a wire mesh conveyor belt, and two or more spray pipe groups 32 are provided, one group on the upper side of the bamboo leaf and the other group on the lower side of the bamboo leaf. The spray pipe group 32 is configured to connect to external clean water and has nozzles facing the bamboo leaf, which can spray clean water onto the surface of the bamboo leaf. Generally, the spraying is done in an atomized manner to avoid damaging the bamboo leaf.

[0054] Furthermore, a third conveyor 40 is disposed in the first drying zone 103, and a fourth conveyor 50 is disposed in the second drying zone 104.

[0055] The third conveyor 40 includes a third conveyor belt 41 and a second conveyor roller group 42, which have the same conveying speed for the bamboo leaves. The third conveyor belt 41 is configured in two groups and is distributed on both sides of the second conveyor roller group 42 on the conveying path. The third conveyor belt 41 is used to convey the bamboo leaves in the first drying zone 103. The second conveyor roller group 42 includes a pair of conveyor rollers 60 that are pressed against the two sides of the bamboo leaves. The conveyor rollers 60 are connected to the air extraction pipe group 15 so that the conveyor rollers 60 can extract residual water from the surface of the bamboo leaves.

[0056] In some embodiments, the third conveyor belt 41 is a wire mesh conveyor belt, which can also play a certain role in draining water while conveying bamboo leaves. Two sets of third conveyor belts 41 are set on the front and rear sides of the second conveyor roller group 42. The two third conveyor belts 41 are set independently. After the second conveyor roller group 42 has dried the water on the surface of the bamboo leaves, the rear third conveyor belt 41 will no longer bring water onto the bamboo leaves.

[0057] Furthermore, such as Figure 7 As shown, the second conveying roller group 42 uses two conveying rollers 60 distributed at the top and bottom as described above. Unlike the first conveying roller group 22, the conveying rollers 60 in the first drying zone 103 are connected to the exhaust pipe group 15. When the conveying rollers 60 come into contact with the surface of the bamboo leaves, they use negative pressure to absorb water and remove water from the surface of the bamboo leaves. When the conveying rollers 60 come into contact with the bamboo leaves, they flatten the bamboo leaves, making it easier to absorb the residual water on the surface of the bamboo leaves and keep the residual water on the surface of the bamboo leaves basically the same, so that the degree of drying of the bamboo leaves is also consistent in the subsequent drying process.

[0058] like Figure 3 and Figure 4As shown, the fourth conveyor 50 includes a fourth conveyor belt 51 and a drying air plate 52. The fourth conveyor belt 51 is used to convey bamboo leaves in the second drying zone 104. The drying air plate 52 is connected to an external air supply device through a drying air duct assembly 53. The drying air plate 52 is distributed on the upper and lower sides of the bamboo leaf conveying path. The drying air plate 52 is configured to direct airflow towards the upper and lower sides of the bamboo leaves.

[0059] In some embodiments, the drying air plate 52 includes a confluence plate 521 and guide fins 522. The confluence plate 521 is connected to the drying air duct assembly 53. The guide fins 522 are disposed on the side of the confluence plate 521 facing the bamboo leaf. The guide fins 522 guide the airflow in the confluence plate 521 obliquely to the surface of the bamboo leaf, using hot air or normal temperature air to dry the surface of the bamboo leaf. Since the conveying roller 60 in the first drying zone 103 draws out the water on the surface of the bamboo leaf, especially the water in the folds, and maintains the consistency of water residue on the overall surface of the bamboo leaf, the airflow in the second drying zone 104 dries the surface of the bamboo leaf faster and at a higher rate. In particular, the drying degree of the bamboo leaf surface is consistent, and there are no problems such as residual water in the folds that could cause subsequent mold growth.

[0060] Optionally, an ultraviolet lamp 523 can be installed between the guide fins 522. The ultraviolet lamp 523 can irradiate and disinfect the surface of the bamboo leaves, which is the final disinfection process to ensure that there are no bacterial residues on the surface of the bamboo leaves.

[0061] In conjunction with the above embodiments, a disinfection zone 101, a washing zone 102, and a drying zone are configured along the path of conveying the bamboo leaves. A pair of conveying rollers 60 are also configured in both the disinfectant water 100 and the subsequent drying zone. When the conveying rollers 60 in the disinfectant water 100 come into contact with the bamboo leaves, they unfold the wrinkles on the surface of the bamboo leaves and simultaneously direct airflow to the surface of the bamboo leaves, generating continuous and gentle physical friction and rinsing, thus improving the disinfection and rinsing effect. When the conveying rollers 60 in the drying zone come into contact with the bamboo leaves, they can absorb the residual water on the surface of the bamboo leaves and maintain the consistency of water residue on the overall surface of the bamboo leaves, thereby accelerating the drying speed and ensuring a consistent degree of drying.

[0062] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
