Description

Technical Field

[0001] This invention relates to the field of bamboo sap water-based roasting technology, specifically to a device and method for continuously roasting fresh bamboo sap. Background Technology

[0002] In existing technologies, there are two methods for producing fresh bamboo sap. One is the dry distillation method, which uses high temperature in a closed, oxygen-deficient environment to make the fresh bamboo sap flow out from the inside of the bamboo. The other is the fire-processing method, which uses direct heating with an open flame or indirect heating with the help of a heat source to make the bamboo sap flow out from the inside of the bamboo after a long period of baking. After researching the fire-processing method, our company found that the most common method on the market is to use a chain to convey bamboo strips, replace the traditional open flame heating source with an electric heating tube, and equip the top with a smoke extraction system. The temperature of the bamboo can be controlled throughout the baking process, which improves the yield and makes the quality more uniform. Because the temperature is controllable, the bamboo will not burn, avoiding the generation of a large amount of smoke and dust.

[0003] However, when using this method, the yield of roasted bamboo strips is low, the tar content is high, the product has a poor taste and a pungent smell. This bamboo sap with a high tar content needs to be filtered multiple times in the later stage to remove the tar content, but it is difficult to remove it completely. In the process, it was clearly found that when the inner wall of the bamboo strips faces the heat source, the roasted bamboo produces more tar content, while when the outer wall of the bamboo strips faces the heat source, the tar content is significantly reduced.

[0004] Furthermore, the heating process is lengthy, requiring traditional heating machines to operate for extended periods. The conveyor belt travels at a slow speed, and workers must place bamboo strips at the beginning of the belt, waiting for each strip to move before adding more. During this process, workers must remain constantly in front of the machine. A single bamboo stalk typically takes about an hour and a half to heat at 120°C to 160°C, and there's a several-second wait between each addition, as the slow conveyor belt speed doesn't provide enough space to place a single bamboo strip. Moreover, multiple bamboo strips need to be heated on the conveyor belt each time, necessitating constant facing of the machine and continuous feeding – a significant waste of time and energy. Summary of the Invention

[0005] The purpose of this invention is to provide a device and method for continuously roasting fresh bamboo sap. In order to solve the problems in the prior art, such as slow bamboo feeding and the large amount of tar when the inner wall of the bamboo is facing the heat source during the heating process, the workers need to spend a lot of time and energy to handle the long heating and feeding process.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A device for continuously roasting fresh bamboo sap includes a conveying module comprising two sets of drive shafts, two sets of chains cooperating with the two sets of drive shafts, a first motor driving the drive shafts, and a transmission plate fixedly disposed between the two sets of chains; a heater disposed below the transmission plate to heat the transmission plate; and a feeding module comprising a feeding box, a layering assembly extending through the feeding box, and a screening assembly disposed on one side of the layering assembly. The feeding box has several sets of storage troughs inside, each including a storage area and a screening area. The feeding box also includes a partition disposed between the storage area and the screening area. The feeding box has several sets of first movable chambers near the storage area and several sets of third movable chambers near the screening area. The layering assembly includes adjusting plates fixedly installed on both sides of the feeding box, and pusher components movable at both ends on the adjusting plates. A second motor is disposed on the pusher component, which drives the pusher component to extend into the storage area and pushes bamboo strips to the extrusion screening group. The component includes a partition with a through hole connecting the storage area and the screening area. Second movable cavities are formed on the upper and lower sidewalls of the through hole. A screening component is symmetrically fixedly distributed on the end face of the second movable cavity within the through hole and extends to the outside of the second movable cavity. The screening component is elastically telescopic and includes a limiting slider. The limiting slider includes a horizontal area and an inclined area away from the end of the corresponding second movable cavity. The inclined end face of the inclined area faces the storage area. When the outer wall of the bamboo strip faces the screening component, the screening component is squeezed to contact the inclined area and squeeze the limiting slider to retract until the bamboo strip passes through. When the inner wall of the bamboo strip faces the screening component, the two ends of the bamboo strip abut against the horizontal area, and the screening component rigidly abuts against the bamboo strip. The feeding module also includes a guiding component, which includes a first guide plate and a second guide plate respectively placed at the bottom of the storage area and the screening area. Both the first and second guide plates are inclined, and their inclined surfaces contact the outer wall of the bamboo strip. The collection module includes collection guide grooves located on both sides of the chain drive direction and below the drive plate.

[0007] Preferably, the gap between the storage area and the sieving area allows the outer wall of the bamboo strip to fit against one side, and the bamboo strip cannot be turned within the storage area and the sieving area.

[0008] Preferably, the pusher component includes a drive plate, a layered plate that is slidably sleeved with the drive plate, and a first elastic member that is fixedly connected between the drive plate and the layered plate. The layered plate has an inclined end on the side near the storage area, and the inclined end of the layered plate faces the guide component.

[0009] Preferably, the drive plate and the layer plate are respectively fixedly provided with a first sliding column and a second sliding column near the two ends of the adjustment plate; The adjusting plate is provided with a limiting slide groove, and the first sliding column and the second sliding column slide within the limiting slide groove. The layered assembly also includes a baffle that slides horizontally along the third movable cavity. The baffle has third sliding columns fixedly disposed at both ends that slide within the limiting slide groove. The limiting slide groove includes a first horizontal section, a first inclined section, and a second inclined section. The first inclined section and the second inclined section are both connected to the first horizontal section, and the inclination angle of the first inclined section is smaller than that of the second inclined section. The horizontal heights of the ends of the first inclined section and the second inclined section away from the first horizontal section are the same.

[0010] Preferably, the adjustment plate is further provided with a first drive slide groove and a second drive slide groove, and the feeding module further includes a drive component, which drives the first sliding column, the second sliding column and the third sliding column to move.

[0011] Preferably, the first drive slide and the second drive slide are both arranged parallel to the first horizontal section. The drive assembly includes a lifting member that slides along the first drive slide. The lifting member includes a sliding plate and a lifting plate. The lifting plate is inclined and forms an angle with both the first inclined section and the second inclined section. The drive assembly also includes a traction plate that slides in the second drive groove and is fixedly connected to a third sliding column. The lifting member and the traction plate are fixedly connected by a connecting rod.

[0012] Preferably, the distance between the baffle and the layered plate is greater than half the length between the two ends of the bamboo strip. A second elastic element is fixedly installed on the end face of the limiting slider away from the inclined area. The other end of the second elastic element is fixedly connected to the inner wall of the second movable cavity. The elasticity of the second elastic element is less than that of the first elastic element. The maximum extension length of the driving plate and the layered plate is equal to the farthest distance between the storage area and the screening area. The push plate component and the limiting slider always keep one of the storage area and the screening area open, so that the bamboo strip is removed from the inside of the feeding box.

[0013] Preferably, the collection module further includes a guide plate disposed above the transmission plate and a condenser disposed on the end face of the guide plate away from the transmission plate. The guide plate is arc-shaped and both ends correspond to the collection guide groove.

[0014] To solve the above-mentioned technical problems, the present invention also provides the following technical solution: a roasting method, which is applied to a device for continuously roasting fresh bamboo sap; and, a batch of bamboo pieces are placed inside the feeding box, the bamboo pieces are made to fall into the storage area by a vibrating screen, the first motor drives the chain to drive the transmission plate, and the second motor is turned on to distinguish the bamboo pieces in the storage area.

[0015] Preferably, the bamboo is sliced ​​before feeding, and unequal portions are cut proportionally according to the diameter of different bamboo nodes, ensuring that the distance between the two ends of the bamboo slices after slicing is always greater than the maximum distance between the inclined areas of the two sets of screening components, and less than the maximum distance between the upper and lower ends of the through holes on the partition.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The bamboo is collected as a whole by the feeding box. After collection, the bamboo strips below to the horizontal position of the through hole are squeezed by the first elastic element between the layered plate and the drive plate. This squeezing action causes the bamboo strips to press against the screening component. During the process of the bamboo's inner and outer walls contacting the bamboo, the inner wall of the bamboo strip, through its own arc-shaped compression, can squeeze along the inclined area of ​​the limiting slider, causing the second elastic element to retract and pass through the limiting slider. When the inner wall of the bamboo contacts the limiting slider, although the two ends are affected by the size of the bamboo itself... The different sizes of bamboo result in different contact positions, but the relatively long horizontal areas of the upper and lower limit sliders can still achieve the contact effect for bamboo with large size differences. This allows the layered plate to adhere to the outer wall of the bamboo strip under the restriction of the limit slide groove, and slide in the gap between the bamboo strip being squeezed and the bamboo strip above. After the baffle retracts, the bamboo strip squeezed on the inner wall can be corrected to the corresponding first guide plate and then adhered to the outer wall of the transmission plate. This achieves the effect of automatic differentiation and downward correction, allowing the workers to feed the material without having to wait in front of the equipment. Attached Figure Description

[0019] To ensure a clear and complete description of the technical solutions in the embodiments of the present invention, and to make the features and advantages more apparent and understandable, the specific implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figures 1 to 6This invention provides a device for continuously roasting fresh bamboo sap, including a conveying module 1. This module includes two sets of drive shafts 11, the distance between which determines the length of the entire conveying line, which can be determined according to actual needs and is not specifically limited here. Two sets of chains 12 are connected to the two sets of drive shafts 11, each chain 12 being connected to one of the two sets of drive shafts 11. The length of each chain 12 is determined by the distance between the two sets of drive shafts 11. The two chains 12 are located at opposite ends of the drive shafts 11. A first motor drives the drive shafts 11, which in turn drives the chains 12. A transmission plate 14 is fixedly installed between the two sets of chains 12. The transmission plate 14 can be made of food-grade polyester PET spiral mesh / polyester dry mesh, which is suitable for high-temperature operation. To meet the requirements, heater 2, using an SRY4 type tubular electric heater, is located below the transmission plate 14, that is, in the middle of the upper and lower layers of the chain 12, to heat the transmission plate 14. Note that heater 2 can be set in layers. A small space can be reserved at the beginning of the movement direction of the chain 12 for preheating, with a specific heating temperature of 90℃~110℃. High temperature is used in the middle stage to extract bamboo sap, with a specific temperature of 160℃~180℃. At the end of the movement direction of the chain 12, the temperature is slightly reduced to 120℃~140℃ to cool and shape the tail end, reducing the production of tar. The temperatures of the front, middle and rear sections are only given as a reference and are not specifically limited. The feeding module 3 includes a feeding box 31, a layered component 32 that runs through the feeding box 31, and a screening component 33 set on one side of the layered component 32.

[0021] Furthermore, the feeding box 31 has several sets of storage troughs 311 inside. The storage trough 311 includes a storage area 3111 and a screening area 3112. The top and bottom of the 3111 are through-connected. The top of the storage area 3111 is sealed and the bottom is open. The feeding box 31 also includes a partition 312 disposed between the storage area 3111 and the screening area 3112. The partition 312 is used to limit the bamboo strips in the storage area 3111 to be inside the storage area 3111, and the two side walls at both ends abut against each other, so that the bamboo strips can always keep one of the inner and outer walls aligned with the partition 312.

[0022] Furthermore, the feeding box 31 is provided with several sets of first movable chambers 313 near the storage area 3111, and the feeding box 31 is provided with several sets of third movable chambers 315 near the screening section 3112. The layering component 32 includes adjusting plates 35 fixedly installed on both sides of the feeding box 31, and push plate components 322 that are movable on the adjusting plates 35 on both sides respectively. A second motor is provided on the push plate component 322. The second motor should be selected to drive intermittently. The second motor drives the push plate component 322 to extend to the storage area 3111. Inside, the pusher plate component 322 pushes the bamboo strips to the extrusion sieving component 33. The partition plate 312 is provided with a through hole 3121 that connects the storage area 3111 and the sieving area 3112. The upper and lower side walls of the through hole 3121 are provided with second movable cavities 314. In the through hole 3121, the sieving component 33 is symmetrically fixedly distributed on the end face of the second movable cavity 314 and extends to the outside of the second movable cavity 314. The sieving component 33 is elastically telescopic and includes a limiting slider 331. The limiting slider 331 includes a horizontal area 3311 and a side area away from the corresponding side area. The inclined area 3312 at the end of the second active cavity 314 is such that its inclined end face faces the storage area 3111. When the outer wall of the bamboo strip faces the sieving component 33, the sieving component 33 is pressed to contact the inclined area 3312 and compress the limiting slider 331 to retract until the bamboo strip passes through. When the inner wall of the bamboo strip faces the sieving component 33, the two ends of the bamboo strip abut against the horizontal area 3311. The sieving component 33 rigidly abuts against the bamboo strip. Since the bamboo strip always has an inner wall and an outer wall after being sliced, the inner wall is in horizontal contact with a flat surface. When the bamboo strip is pressed, both ends can contact the plane simultaneously. However, when the outer wall of the bamboo strip contacts a plane, only one raised arc-shaped part can contact the plane. Due to the characteristics of its own arc surface, the elastically set screening component 33 can be contracted during the pressing process. This allows the bamboo strip to be pressed against the inclined plane on both sides by its own arc-shaped protrusion. After passing through the screening component 33, the screening component 33 is reset. After the bamboo strip passes through the screening component 33, it falls through the screening section 3112.

[0023] The further feeding module 3 also includes a guiding component 34, which includes a first guide plate 341 and a second guide plate 342 respectively placed at the bottom of the storage area 3111 and the screening area 3112. Both the first guide plate 341 and the second guide plate 342 are inclined and their inclined surfaces are in contact with the outer wall of the bamboo strip. After passing through the screening component 33, the bamboo strip is guided by the second guide plate 342 and falls onto the transmission plate 14, keeping its outer wall in contact with the transmission plate 14. At the same time, when the product located in the storage area 3111 falls, it can also be ensured that it falls onto the transmission plate 14 and keeps its outer wall in contact with the transmission plate by contacting the first guide plate 341.

[0024] Furthermore, the collection module 4 includes collection guide channels 41 disposed on both sides of the chain 12 in the transmission direction and located below the transmission plate 14. The guide channels 41 can be inclined, and a guide device can be opened at the lowest point of the guide channels 41 to connect to the inside of the container for storage.

[0025] In actual use, the first motor is turned on, and the chain 12 drives the transmission plate 14 to start the conveying. First, bamboo strips are placed inside the storage area 3111. When the bamboo strips fall to the horizontal height of the through hole 3121, the second motor drives the pushing component 322 to push the corresponding bamboo strips to the contact limit slider 331. If the inner wall of the bamboo strip faces the limit slider 331, both ends of the bamboo strip will directly abut against the horizontal area 3311 of the upper and lower limit sliders 331. If the outer wall of the bamboo strip faces the limit slider 331, any point of the raised arc-shaped part in the middle of the bamboo strip abutting against the limit slider 331 will ensure contact with the inclined area 3312. This ensures that the bamboo strips can be pushed by the pushing component 322 and overcome the elastic potential energy of the screening component 33, thus allowing the bamboo strips to be conveyed. When the bamboo strip is pushed into the screening section 3112, if the inner wall of the bamboo strip faces the limiting slider 331, both ends of the bamboo strip will directly contact the horizontal section 3311 of the limiting slider 331. The horizontal section 3311 cannot be pushed because it is abutted by the side walls on both sides of the second movable cavity 314. The pushing component 322 is also set to be elastic. It is only necessary to ensure that the elasticity of the pushing component 322 is greater than the elasticity of the screening component 33. In the end, since the bamboo strip with the inner wall facing the limiting slider 331 cannot pass through the partition 312, the bamboo strip with the outer wall facing the limiting slider 331 can pass through the partition 312, thereby separating the two different bamboo strips. Finally, they fall onto the corresponding first guide plate 341 and second guide plate 342 respectively, and the outer wall can be attached to the transmission plate 14.

[0026] Example 2 Please see Figures 7 to 13This invention provides a device for continuously roasting fresh bamboo sap, including a storage area 3111 and a sieving area 3112. The gap between these areas allows the outer wall of the bamboo strips to adhere to one side, and the bamboo strips cannot turn within the storage area 3111 and the sieving area 3112. The push plate component 322 includes a drive plate 3221. The drive plate 3221 can be made of a rigid material to ensure that it does not deform after multiple collisions with the bamboo strips. It also needs to be easy to groove and process. The specific material is not limited here. The layered plate 3222, which is slidably sleeved with the drive plate 3221, and the first elastic member 3223, which is fixedly connected between the drive plate 3221 and the layered plate 3222, can adopt a spring sleeve telescopic rod structure. Multiple sets of such elastic structures can be provided, or other elastic structures are not specifically limited here. The layered plate 3222 has an inclined end on the side near the storage area 3111. The inclined end can move along... The bamboo strips are displaced and contracted along their inclined surfaces. When the layering plate 3222 comes into contact with the bamboo strips, there are two situations. One is that the inner wall faces the layering plate 3222. In this case, the layering plate 3222 can come into contact with the inside of the bamboo strip. Since the inside of the bamboo strip is curved, the layering plate 3222 will not shift to the sides. In this case, the layering plate 3222 can only move towards the screening component 33. The result is the same as in Embodiment 1, and will not be repeated here. The other situation is that the layering plate 3222 comes into contact with the outer wall of the bamboo strip. In this case, the layering plate 3222 can move to the sides along the curved surface of the outer wall of the bamboo strip. It should be noted that the inclined end of the layering plate 3222 faces the guide component 34. When the pressure is applied, the bamboo strip in contact with the outer wall can be pressed downward, causing it to leave the storage area 3111 and slide onto the transmission plate 14, thereby completing the correction. The specific details are the same as in Embodiment 1, and will not be repeated here.

[0027] The drive plate 3221 and the layering plate 3222 are respectively fixedly provided with a first sliding post 351 and a second sliding post 352 near the two ends of the adjusting plate 35. Both the first sliding post 351 and the second sliding post 352 need to maintain a certain rigidity. The material of the first sliding post 351 and the second sliding post 352 is not specifically limited here. The adjusting plate 35 is provided with a limiting groove 353. Both the first sliding post 351 and the second sliding post 352 slide within the limiting groove 353. The layering component 32 also includes a baffle 323 that slides horizontally along the third movable cavity 315. 323 is used to alternately block the bamboo strips in the storage area 3111 and the sieving area 3112. The baffle 323 has three sliding posts 354 fixed at both ends that slide within a limiting groove 353. The limiting groove 353 includes a first horizontal section a, a first inclined section b, and a second inclined section c. Both the first inclined section b and the second inclined section c are connected to the first horizontal section a, and the inclination angle of the first inclined section b is smaller than that of the second inclined section c. This ensures that the movement process when the layered plate 3222 contacts the outer wall of the bamboo strip is as follows: due to the first sliding post 351 and the second sliding post 354... Both are limited by the first horizontal segment a, so they cannot rise. The drive plate 3221 can only continue to advance towards the bamboo strip. The front end of the layered plate 3222 is abutted by the limiting slider 331, and the rear end is squeezed by the drive plate 3221. At this time, the first elastic member 3223 between the drive plate 3221 and the layered plate 3222 is squeezed and contracted. Subsequently, when the drive plate 3221 moves to the position of the first inclined segment b, the drive plate 3221 is restricted in its upward space, and the first sliding column 351 can enter the first inclined segment b. At the same time, the second sliding column 352 can enter. The second inclined segment c, and the different inclination angles of the first inclined segment b and the second inclined segment c, will cause the gap between the first sliding column 351 and the second sliding column 352 to increase. At the same time, the elasticity of the first elastic element 3223 is fully released. During this process, the end of the layered plate 3222 is always in contact with the outer wall of the bamboo strip, which can separate the bamboo strip that is abutted from the upper bamboo strip. Since the horizontal height of the first inclined segment b and the second inclined segment c away from the first horizontal segment a is the same, the layered plate 3222 and the drive plate 3221 can eventually maintain a horizontal state.

[0028] Furthermore, the adjusting plate 35 is also provided with a first driving slide 355 and a second driving slide 356. The feeding module 3 also includes a driving component 36, which drives the first sliding column 351, the second sliding column 352 and the third sliding column 354 to move, so that the first sliding column 351, the second sliding column 352 and the third sliding column 354 can move synchronously to ensure the stability of the transmission.

[0029] Furthermore, both the first drive slide 355 and the second drive slide 356 are arranged parallel to the first horizontal segment a. The drive assembly 36 includes a lifting member 361 that slides along the first drive slide 355. The lifting member 361 includes a sliding plate 3611 and a lifting plate 3612. The lifting plate 3612 is inclined and forms an angle with both the first inclined segment b and the second inclined segment c. The drive assembly 36 also includes a traction plate 3613 that slides in the second drive groove 356 and is fixedly connected to the third sliding column 354. The lifting member 361 and the traction plate 3613 are fixedly connected by a connecting rod 3614. During the horizontal displacement process, the lifting plate 3612 can more smoothly enable the first sliding column 351 located between the first horizontal segment a and the first inclined segment b to achieve the effect of tilting upward more smoothly, and avoid jamming.

[0030] Furthermore, the distance between the baffle 323 and the layered plate 3222 is greater than half the length between the two ends of the bamboo strip. This ensures that when the baffle 323 slides to its maximum extent, it alternately opens and closes the bottom of the storage area 3111 and the sieving area 3112. A second elastic element 332 is fixedly installed on the end face of the limiting slider 331 away from the inclined area 3312. The other end of the second elastic element 332 is fixedly connected to the inner wall of the second movable cavity 314. The elasticity of the second elastic element 332 is less than that of the first elastic element 3223. Note that this refers to the elasticity of the layered plate. When 3222 comes into contact with the inner wall of the bamboo strip, the first elastic element 3223, due to its own elasticity, will not cause the limiting slider 331 to contract when it is pressed against the outer wall of the bamboo strip. The maximum extension length of the drive plate 3221 and the layer plate 3222 is equal to the farthest distance between the storage area 3111 and the screening area 3112, ensuring that the layer plate 3222 can transport the bamboo strip through the limiting slider 331. The push plate component 322 and the limiting slider 331 always keep one of the storage area 3111 and the screening area 3112 open, so that the bamboo strip leaves the inside of the feeding box 31.

[0031] The collection module 4 also includes a guide plate 42 disposed above the transmission plate 14, and a condenser 43 disposed on the end face of the guide plate 42 away from the transmission plate 14. The guide plate 42 is arc-shaped, and both ends correspond to the collection guide groove 41. When the water vapor generated by heating the bamboo strips comes into contact with the guide plate 42, it can slide down along the guide plate 42 into the bottom guide groove 41 due to the action of the condenser 43. At the same time, the bamboo sap dripping from both ends of the bamboo can also be directly dropped into the guide groove 41.

[0032] It is important to note that when the outer curved surface of the bamboo strip cannot be pushed, the pushing component 322 must not be forced against it, but rather moved upwards while still attached to the bamboo strip. Therefore, during the pushing process, it should be kept against the surface of the bamboo strip and moved upwards. During this process, regardless of whether the bottom baffle 323 is open, closed, partially open, or fully open, it can avoid jamming. The pushing component 322 rises while attached to the outer wall of the bamboo strip. The connection point between a and b / c is the maximum elastic force that the spring of the pushing component 322 can withstand. At this point, the pushing component can move upwards to areas b and c. This also corresponds to the pushing component 322 rising to overcome jamming when the outer wall of the bamboo strip is blocked. When the pushing component 322 rises, regardless of whether the baffle 323 is open or not, the gap between the pushing component 322 and the baffle can still accommodate the bamboo strip. After the baffle is fully opened, the bamboo strip falls down. When the pushing component 322 is fully reset, the baffle closes, and the bamboo strip on top can fall down.

[0033] The rest of the structure is the same as in Example 2.

[0034] In practical use, there are two scenarios. First, the bamboo strip abutted by the layered plate 3222 is in contact with the outer wall. At this time, when the second motor drives the lifting plate 3612 to move and drives the first sliding column 351 to move the driving plate 3221, the layered plate 3222 is moved towards the bamboo strip through the first elastic element 3223. When it contacts the outer wall of the bamboo strip, the layered plate 3222 stops moving, while the driving plate 3221 continues to move. During this process, the first elastic element 3223 is compressed, and the first sliding column 351 moves to the first inclined section b and... At the connection point of the first horizontal segment a, the first elastic element 3223 reaches the maximum compression limit. At this time, due to the inclined surface of the lifting plate 3612, the first sliding column 351 and the second sliding column 352 can be displaced upward along the first inclined segment b and the second inclined segment c respectively. At the same time, due to the increased distance between the first inclined segment b and the second inclined segment c at the same horizontal height, the elastic potential energy of the first elastic element 3223 is released. At the same time, the layered plate 3222 can always adhere to the bamboo strip being pressed, thereby separating the bamboo strip above.

[0035] In the second scenario, the bamboo strip abuts against the layered plate 3222 at the inner wall. In this case, the second motor drives the lifting plate 3612 to move and drives the first sliding column 351 to move the drive plate 3221. At the same time, the first elastic element 3223 drives the layered plate 3222 to move towards the bamboo strip. When it contacts the inner wall of the bamboo strip, the drive plate 3221 and the layered plate 3222 continue to move, while squeezing the inclined area 3312 of the limiting slider 331 and pushing the bamboo strip through the limiting slider 331 to reach the screening area 3112. The drive plate 3221 moves to the maximum limit and stops moving. At this time, when the drive plate 3221 resets next time, the bamboo strip can fall onto the transmission plate 14.

[0036] This process leads to various scenarios, such as the bamboo strip being squeezed having its inner wall facing the layered board 3222, and the bamboo strip being squeezed also having its inner wall facing the layered board 3222.

[0037] The compressed bamboo strip has its inner wall facing the layered board 3222, and the top of the compressed bamboo strip has its outer wall facing the layered board 3222.

[0038] The compressed bamboo strip has its outer wall facing the layered board 3222, and the top of the compressed bamboo strip has its inner wall facing the layered board 3222.

[0039] The compressed bamboo strip has its outer wall facing the layered board 3222, and the top of the compressed bamboo strip also has its outer wall facing the layered board 3222. This solution can address all four of these situations.

[0040] Example 3 Please see Figures 1 to 13 This invention provides a device for continuously roasting fresh bamboo sap. Further, a batch of bamboo slices is placed inside the feeding box 31, and a vibrating screen is used to cause the bamboo slices to fall into the storage area 3111. A vibrating screen can be used to shake the bamboo slices, but it is necessary to ensure that the vibrating screen does not collide with the device to avoid damage. This avoids the need for workers to stand in front of the equipment constantly waiting for feeding and turning the bamboo slices. The device controls the first motor to drive the chain 12, which in turn drives the transmission plate 14. The second motor is activated to separate the bamboo slices in the storage area 3111, thus achieving a rapid feeding process.

[0041] Furthermore, before feeding the bamboo strips, the bamboo is sliced ​​and cut into unequal portions according to the diameter of different bamboo nodes. This ensures that the distance between the two ends of the bamboo strips after slicing is always greater than the maximum distance between the inclined areas of the two sets of screening components 33, and less than the maximum distance between the upper and lower ends of the through hole 3121 on the partition plate 312. This allows for the adaptation of more bamboo strip sizes and enables their use in this solution.

[0042] Meanwhile, during the roasting process, bamboo slices can be placed on the transmission plate 14, with the conveyor belt speed set to 0.15m / min-0.225m / min. The initial temperature is controlled at 90℃~110℃, which is conducive to the outflow of sugars and amino acids. The middle temperature is controlled at 160℃~180℃. Condensers 43 are installed at both ends of the bamboo to condense the bamboo sap and steam sprayed from the bamboo slices. The condensed part flows back to the collection guide trough 41 for collection. High temperature helps chemical reactions to occur inside the bamboo, and condensation helps retain more effective components. The final temperature is controlled at 120~140℃, with moving heating. Anti-condenser 43 is set to prevent the smoke tar and acidic substances from mixing with the fresh bamboo sap during the final bamboo roasting process, ensuring that the product pH is within the specified range, the color is natural, the smell is fresh, and there is no obvious odor. The roasting temperature control range for bamboo slices is fixed at 160℃~180℃. In this temperature range, only the effective components of the active bamboo sap containing water inside the bamboo are heated and vaporized to form water vapor. The distillation process involves the separation of tar and large-molecule acidic substances produced during roasting. These substances have boiling points significantly higher than 180°C and cannot be vaporized under these conditions. Instead, they remain as liquid heavy impurities attached to the bamboo strips and inside the front roasting chamber. They are not transported to the condenser 43 along with the bamboo sap steam. The pure bamboo sap steam released by the bamboo strips is transported into the condenser 43 through pipes. The condenser 43 is circulated with cooling water to quickly cool and liquefy the high-temperature steam. Only the bamboo sap steam, free of tar and acidic impurities, is condensed and collected as the finished fresh bamboo sap. The high-boiling-point tar and acidic substances are retained in the front roasting area and cannot mix into the condensed and collected finished product. This avoids the mixing of tar and acidic substances from the later bamboo roasting process with the fresh bamboo sap. After separation by the condenser 43, the pH value of the final collected fresh bamboo sap can be stably controlled within the specified standard range. The liquid is naturally clear and transparent, without any burnt or acidic odors, and has a fresh and pure overall smell.
