Description

Technical Field

[0001] The present invention relates to the technical field of Indocalamus leaf processing, and more particularly to an Indocalamus leaf conveying device capable of disinfecting Indocalamus leaves. Background Art

[0002] Indocalamus leaves mainly come from the leaves of Indocalamus tessellatus or other large bamboo species. Indocalamus leaves are usually relatively broad, being oblong or lanceolate in shape. The texture of the Indocalamus leaf blade is thick and flexible, not easily broken, and is especially suitable for wrapping zongzi, capable of endowing zongzi with a unique fresh fragrance and shape. In the Indocalamus leaf processing process, disinfection is a key link to ensure food safety. In order to improve efficiency and hygiene standards, special conveying equipment is used to process Indocalamus leaves, and the conveying equipment is an indispensable part to achieve an efficient, uniform, and controllable disinfection process.

[0003] As the packaging of zongzi, Indocalamus leaves need to maximize the protection of the natural color, fresh fragrance, and flexible texture of Indocalamus leaves during the disinfection process. Therefore, currently, the method of soaking in disinfectant solution followed by rinsing is often used to disinfect and clean Indocalamus leaves. In this way, high-efficiency disinfection and thorough residue removal can be achieved on the surface of Indocalamus leaves. However, the surface of Indocalamus leaves has a villous structure, and there are also natural folds along the width direction of the leaf. When soaking in the disinfectant solution, the Indocalamus leaves are stacked on top of each other. Combining the villi and folds on the surface of the Indocalamus leaves will affect the contact effect between the Indocalamus leaves and the disinfectant solution, resulting in blind spots during the disinfection of Indocalamus leaves, and also causing cross-contamination during the subsequent conveying.

[0031] In order to better understand the technical content of the present invention, specific embodiments are given and described in conjunction with the accompanying drawings as follows.

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

[0033] Among them, multiple groups of parallel conveying channels are arranged in the width direction in the conveyor 10. In each conveying channel, a disinfection area 101, a cleaning area 102, and a drying area are sequentially arranged along the conveying direction of the bamboo leaves. The conveying direction is perpendicular to the width direction. The first conveyor 20 is arranged in the disinfection area 101, and disinfection water 100 is provided in the disinfection area 101. The second conveyor 30 is arranged in the cleaning area 102 and can wash the disinfection water 100 on the surface of the bamboo leaves. The third conveyor 40 and the fourth conveyor 50 are both arranged in the drying area 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 bracket 11 to keep the structure of the conveyor 10 stable. An isolation cover 12 is also configured above the cleaning area 102 and the drying area to reduce the splashing of water. 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 mode, avoiding the cleaning blind spots caused by the overlapping of bamboo leaves. In this way, when conveying the bamboo leaves, the disinfection and cleaning of the surface of the bamboo leaves will be more thorough, and cross-contamination caused by the un-disinfected areas existing due to the blind spots during the subsequent conveying process can be avoided.

[0035] Furthermore, the drying area includes a first drying area 103 and a second drying area 104. Partition plates 13 are also arranged between the disinfection area 101, the cleaning area 102, the first drying area 103, and the second drying area 104 arranged sequentially along the conveying direction of the bamboo leaves. Through the separation of the partition plates 13, the disinfection water 100, clean water, drained residual water, etc. in each area are separated by the partition plates 13, and independent conveyors are arranged in each area, which can avoid the mutual communication between different areas and largely avoid the situation of cross-contamination. In addition, drainage pipelines are configured below each area and can drain water independently.

[0036] As Figure 2 、 Figure 3 and Figure 5 shown, the first conveyor 20 includes a first conveyor belt 21 and a first conveyor roller set 22 with the same conveying speed for the bamboo leaves. And a part of the first conveyor belt 21 is arranged in the disinfection water 100. When the conveying speeds of the first conveyor belt 21 and the first conveyor roller set 22 for the bamboo leaves are the same, when the bamboo leaves enter the first conveyor roller set 22 from the first conveyor belt 21, there will be no pulling situation due to the speed difference, which can protect the bamboo leaves and avoid the bamboo leaves being pulled and damaged.

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

[0038] During operation, the bamboo leaves are placed on the first conveyor belt 21 from the feeding side of the first conveyor belt 21, and the length of the bamboo leaves is kept parallel to the conveying direction of the first conveyor belt 21. As the first conveyor belt 21 conveys, the bamboo leaves gradually enter below the liquid level of the disinfectant water 100, and the disinfectant water 100 is used to disinfect the bamboo leaves. However, due to the natural folds and villus structures on the surface of the bamboo leaves, it is difficult for the disinfectant water 100 to penetrate into the folds. Therefore, even if a single leaf contacts the disinfectant water 100 without overlap, there will still be disinfection blind spots. In order to disinfect this folded area, the bamboo leaves will pass through the first conveyor roller group 22 under the conveyance of the first conveyor belt 21, and the folded structure on the surface of the bamboo leaves is flattened by the first conveyor roller group 22, so as to promote the contact and disinfection of the surface of the bamboo leaves with the disinfectant water 100.

[0039] In some embodiments, the disinfectant water 100 uses a low-concentration chlorine dioxide solution. The low-concentration chlorine dioxide solution has strong bactericidal ability (especially for molds, spores, viruses), and has a fast action speed, extremely low residue, and almost no odor residue. Combined with subsequent clean water spraying, efficient disinfection and thorough residue removal can be achieved.

[0040] As Figure 2 and Figure 3 shown, the first conveyor roller group 22 includes a pair of conveyor rollers 60 that roll on both sides of the bamboo leaves. When the two conveyor rollers 60 distributed vertically contact the bamboo leaves, the bamboo leaves are flattened by the rolling of the conveyor rollers 60, and the folds on the surface of the bamboo leaves are spread out. At the same time, the conveyor rollers 60 are connected to the air supply pipe group 14, and air can be led to the surface of the bamboo leaves to form bubbles in the disinfectant water 100 on the surface of the bamboo leaves. During the process of the bubbles flowing on the surface of the bamboo leaves, continuous and gentle physical friction and scouring are generated on the surface of the bamboo leaves, which can more effectively loosen and remove impurities such as sediment and microbial biofilms attached to the folds of the leaves, the back villi and the depths of the textures. At the same time, the bubble disturbance can destroy the static boundary layer formed by the liquid on the surface of the bamboo leaves, accelerate the mass exchange between the disinfectant water 100 and the leaf surface, ensure that the disinfectant fully contacts all areas, and can protect the surface structure of the bamboo leaves compared with mechanical (brush, etc.) washing methods.

[0041] In this way, when the conveying roller 60 comes into contact with the bamboo leaves, it can not only flatten the bamboo leaves, but also introduce air bubbles to the surface of the bamboo leaves. The mechanical action generated by the scouring of the air bubbles on the surface of the bamboo leaves is gentle (compared with brushing or strong water flow impact). It can improve the cleaning effect while reducing the physical damage to the fiber structure on the surface of the bamboo leaves, and better maintain its flexibility and integrity. For the bamboo leaves used as zongzi leaves, the appearance integrity of the bamboo leaves is particularly important. At the same time, the more impurities are removed in advance by air bubbles during the disinfection process, the easier it is to completely remove the residual disinfectant and impurities in the subsequent rinsing process.

[0042] Further, as Figure 5 and Figure 6 shown, the conveying roller 60 includes a contact ring 61 and a roller body 62. The contact ring 61 is fixedly sleeved on the outer side wall of the roller body 62, and a plurality of them are arranged along the axial direction of the roller body 62. The circumferential surface of each contact ring 61 is provided with contact portions 611 and air guiding portions 612 that are distributed alternately in a cycle.

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

[0044] In this way, when the contact ring 61 rolls on the surface of the bamboo leaves, in the circumferential direction (that is, when the contact ring 61 rotates), the contact portions 611 and the air guiding portions 612 contact the surface of the bamboo leaves in a cycle, and in the axial direction (that is, the width direction of the bamboo leaves), the contact portions 611 and the air guiding portions 612 also contact the surface of the bamboo leaves in a cycle. The contact portion 611 can prevent slipping between the bamboo leaves and the contact ring 61. At the same time, when the contact ring 61 rotates, the air guiding portion 612 can always output air bubbles to the surface of the bamboo leaves, and through the scouring action of the air bubbles on the surface of the bamboo leaves, it promotes the contact and disinfection of the disinfectant with the bamboo leaves.

[0045] Further, each air guiding portion 612 is provided with an air guiding port 613, and a communication pipe 621 is provided on the roller body 62 corresponding to each air guiding port 613, and the communication pipe 621 is communicated with the air guiding port 613.

[0046] Furthermore, the conveying roller 60 further includes a wind guiding rod 63 arranged inside the roller body 62. The wind guiding rod 63 is rotatably arranged relative to the roller body 62. The end of the wind guiding rod 63 is fixed to the inner wall of the conveyor 10. The roller body 62 is driven to rotate by a driving 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 driving device can adopt a combined drive of a motor and a transmission box to control the rotation speed of the roller body 62 and cooperate with the conveying speed of the first conveyor belt 21, so that the conveying speeds of the conveying roller 60 and the first conveyor belt 21 for the bamboo leaves are kept consistent. During driving, the air guiding rod 63 remains relatively fixed with respect to the conveyor 10, and the roller body 62 together with the contact ring 61 rotates outside the air guiding rod 63, and the bamboo leaves are conveyed by contacting the bamboo leaves through the contact ring 61.

[0048] Furthermore, an air guiding channel 631 communicating with the air supply pipe group 14 is provided on the air guiding rod 63. The air guiding channel 631 faces the side of the passing path of the bamboo leaves. As the roller body 62 rotates outside the air guiding rod 63, a plurality of communicating pipes 621 distributed in the circumferential direction are cyclically communicated with the air guiding channel 631, and the air flow is guided to the surface of the bamboo leaves to form bubbles in the disinfectant water 100.

[0049] The air guiding channel 631 can be set as a channel with a sector-shaped or rectangular cross-section. As Figure 6 shown, when the contact ring 61 and the roller body 62 rotate outside the air guiding rod 63, the air guiding channel 631 always faces the surface of the bamboo leaves. When a certain communicating pipe 621 rotates to be communicated with the air guiding channel 631, the air flow passage is opened, and the air flow enters from the air supply pipe group 14 and passes through the air guiding channel 631, the communicating pipe 621 to the air guiding port 613, and the air flow (bubbles) is guided to the surface of the bamboo leaves. The air guiding port 613 can be constructed in the shape of a flared opening. In cooperation with the plane of the surface of the air guiding part 612, the air flow (bubbles) can be guided to the front and rear sides to expand the contact area between the bubbles and the bamboo leaves, so that the contact part 611 in contact with the bamboo leaves can still be washed and disinfected by the bubbles.

[0050] In a preferred embodiment, the contact ring 61 can be made of a silica gel ring. The silica gel material can ensure that when contacting the bamboo leaves, it can also avoid damaging the surface structure of the bamboo leaves as much as possible. The number of the contact parts 611 in the circumferential direction is equal to the number of the air guiding parts 612 and is equal to N, where 3≤N≤10. It should be understood that the number of the contact parts 611 and the air guiding 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 part 611 on the bamboo leaves and the effect of cooperating with the air guiding part 612 to convey bubbles to the surface of the bamboo leaves are better.

[0051] As Figure 2 and Figure 3 shown, the second conveyor 3 include a second conveyor belt 31 and a spray pipe group 32. The second conveyor belt 31 is used to convey the bamboo leaves in the cleaning area 102. The spray pipe group 32 is communicated with an external water supply device and is distributed on the upper and lower sides of the conveying path of the bamboo leaves. The spray pipe group 32 is configured to guide and spray water onto the upper and lower sides of the bamboo leaves.

[0052] After the indigo leaves are contacted with the disinfectant 100 for disinfection in the disinfection area 101, disinfectant will remain on the surface of the indigo leaves. In the subsequent transportation, in order to completely remove the residual disinfectant, the indigo leaves are sprayed with clean water on the upper and lower sides of the indigo leaves through the spray pipe group 32 in the cleaning area 102 to clean and remove the residual disinfectant.

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

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

[0055] Among them, the third conveyor 40 includes a third conveyor belt 41 and a second conveyor roller group 42 with the same conveying speed for the indigo leaves. The third conveyor belt 41 is set as 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 indigo leaves in the first drying area 103. The second conveyor roller group 42 includes a pair of conveyor rollers 60 that are pressed on both sides of the indigo leaves, and the conveyor rollers 60 are connected to the exhaust pipe group 15 so that the conveyor rollers 60 can suck the residual water on the surface of the indigo leaves.

[0056] In some embodiments, the third conveyor belt 41 is a wire mesh conveyor belt, which can not only convey the bamboo leaves, but also play a certain role in draining water. Two groups of third conveyor belts 41 are set on the front and back 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 third conveyor belt 41 on the rear side will no longer bring water to the bamboo leaves.

[0057] Further, such as Figure 7 As shown, the second conveyor roller group 42 adopts the two conveyor rollers 60 distributed above and below. Unlike the first conveyor roller group 22, the conveyor rollers 60 in the first drying area 103 are connected to the exhaust pipe group 15. When the conveyor rollers 60 are in contact with the surface of the reed leaves, negative pressure water absorption is adopted to remove the water on the surface of the reed leaves. When the conveyor rollers 60 are in contact with the reed leaves, the reed leaves are flattened, making it easier to absorb the residual water on the surface of the reed leaves, and keeping the residual water at various places on the surface of the reed leaves basically consistent, so that the degree of drying of the reed leaves can also be kept consistent during the subsequent drying process.

[0058] like Figure 3 and Figure 4As shown in the figure, the fourth conveyor 50 includes a fourth conveyor belt 51 and drying air plates 52. The fourth conveyor belt 51 is used to convey the bamboo leaves in the second drying area 104. The drying air plates 52 are communicated with an external air supply device through a drying air duct group 53. The drying air plates 52 are distributed on the upper and lower sides of the bamboo leaf conveying path, and the drying air plates 52 are configured to direct the air flow to spray onto the upper and lower sides of the bamboo leaves.

[0059] In some embodiments, the drying air plates 52 include a confluence plate 521 and diversion fins 522. The confluence plate 521 is communicated with the drying air duct group 53. The diversion fins 522 are arranged on one side of the confluence plate 521 facing the bamboo leaves. The diversion fins 522 obliquely direct the air flow in the confluence plate 521 to the surface of the bamboo leaves, and use hot air or normal temperature air to dry the surface of the bamboo leaves. Since in the first drying area 103, the conveying roller 60 sucks and discharges the water on the surface of the bamboo leaves, especially the water in the folds, and maintains the consistency of the water residue on the overall surface of the bamboo leaves, the drying speed of the air flow on the surface of the bamboo leaves in the second drying area 104 is accelerated, and the drying rate is high. In particular, the drying degree of the surface of the bamboo leaves is consistent, and there are no problems such as residual water in the folds, resulting in subsequent mildew.

[0060] Optionally, ultraviolet lamps 523 can also be arranged between the diversion fins 522. The ultraviolet lamps 523 can irradiate and disinfect the surface of the bamboo leaves, which is the last disinfection process to ensure that there is no bacterial residue on the surface of the bamboo leaves.

[0061] Combined with the above embodiments, on the path of conveying the bamboo leaves, a disinfection area 101, a cleaning area 102 and a drying area are configured. At the same time, a pair of conveying rollers 60 are arranged in both the disinfectant water 100 and the subsequent drying area. When the conveying rollers 60 in the disinfectant water 100 contact the bamboo leaves, the folds on the surface of the bamboo leaves are spread out, and at the same time, an air flow is led to the surface of the bamboo leaves to generate continuous and gentle physical friction and scouring on the bamboo leaves, improving the disinfection and rinsing effect. When the conveying rollers 60 in the drying area contact the bamboo leaves, the residual water on the surface of the bamboo leaves can be sucked out, and the consistency of the water residue on the overall surface of the bamboo leaves is maintained, promoting the drying speed and the drying degree to be consistent.

[0062] Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Those with ordinary knowledge in the technical field to which the present invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to what is defined by the claims.
