[0002] Grass jelly powder is a food raw material made from jelly grass (also known as fairy grass, grass jelly) as the main raw material. Grass jelly powder is rich in nutrients such as protein, vitamins, amino acids, cellulose, minerals, etc. In the production and processing of grass jelly powder, it is necessary to first steam the grass jelly, then filter out the grass jelly concentrate, and finally make jelly or grass jelly powder. However, in the production and processing of the prior art, the inventors have found the following usage problems:

[0003] The prior art discloses a new type of air flow spray dryer (202410479230.4), comprising a shell, a hot air distribution mechanism is arranged on the top of the shell, a spray gun is arranged in the shell, the opening of the spray gun faces upward, the opening of the spray gun is located on the axis of the shell, the spray gun is located at the lower side of the hot air distribution mechanism, a fluidized bed is arranged at the bottom of the shell, an air supply mechanism is arranged on the lower side of the fluidized bed, and a discharge mechanism is arranged on the upper side of the fluidized bed.

[0019] A method for using a grass jelly powder spray drying device, comprising:

[0020] Step 1: Before work, the staff needs to connect the container storing the grass jelly concentrate to the left and right ends of the first guide tube through pipes, and then the grass jelly concentrate can be sucked into the position of the third perforation from the left and right ends of the first guide tube through two electric pumps. Due to the water pressure, the grass jelly concentrate will enter the cavity of the guide tube through the third perforation, and then enter the cavity of the second guide tube. The second perforation can guide the grass jelly concentrate and guide part of the grass jelly concentrate to the two ends of the second guide tube, so that the atomizing nozzles at the left and right ends can perform spraying operations. The first fixed plate can limit the first drive motor. The second fixing plate and the first connecting groove can seal the first fixing plate, and the two first connecting grooves can clamp and limit the guide tube. The first fixing plate fits the wall surface of the connecting plate, and the guide tube can be further limited. When the output ends of the two first driving motors rotate, the spur gears can be driven to rotate, and the rotation of the spur gears can drive the connecting plate to rotate through the gear teeth meshing therewith, and the rotation of the connecting plate can drive the guide tube to rotate, and the rotation of the guide tube can drive the second guide tube to rotate through the first perforation, thereby driving the multiple atomizing nozzles to rotate;

[0021] Step 2: According to the first step, during the rotation of the second guide tube, the heating tube can be driven to rotate, and the heating tube is heated by the heat supply tube. Therefore, during the rotation of the heating tube, the heat dissipation range is increased at the same time, and during the rotation, the concentrated grass jelly liquid is contacted to evaporate quickly;

[0022] The third step: when the output end of the second driving motor rotates, the threaded rod can be driven to rotate, and the rotation of the threaded rod can drive the lifting block threadedly connected thereto to move up and down. The lifting block cannot rotate due to the limitation of the second limiting groove. When the lifting block moves up and down, it can drive the lifting rod to move up and down, and then drive the lifting ring to move up and down through the second connecting groove. When the threaded rod rotates, the rubber ring can be driven to rotate through the connection between the connecting block and the first limiting groove. The rotation of the rubber ring can drive the lifting ring to rotate by fitting with the side wall of the lifting ring. The rotation of the lifting ring can drive the scraper to rotate, so that the scraper can rotate to scrape off the residue on the inner wall of the atomizing drying box cavity. When the threaded rod rotates, the two limiting plates can be driven to move up and down. The two limiting plates cannot rotate due to the limitation of the second limiting groove. Therefore, the up and down movement of the gear teeth and the limiting plates can drive the rubber ring to move up and down.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In summary, by arranging a spray device, a heat conducting device and a wall scraping device, the grass jelly concentrate can be sprayed and atomized through the spray device, and then the grass jelly concentrate is evaporated and dried by the heat of the heat conducting device to form a powder. The residue on the inner wall of the atomizing drying box cavity can also be scraped off by the wall scraping device. Compared with the prior art, it is easy to use and has a simple structure.

[0025] 2. In summary, by providing a first guide tube, an electric pump, a third perforation, a guide tube, a second guide tube, a second perforation and an atomizing nozzle, the grass jelly concentrate can be introduced into the cavity of the second guide tube through two electric pumps in cooperation with the first guide tube, and then sprayed out through multiple atomizing nozzles. By providing multiple atomizing nozzles, the spray volume can be increased. By introducing the grass jelly concentrate from the left and right ends of the first guide tube, its flow rate can be increased, thereby increasing work efficiency. It is easy to use and has a simple structure.

[0026] 3. In summary, by arranging a heating tube, a second guide tube, a heat supply tube, a first drive motor, a spur gear, gear teeth and a connecting plate, the rotation of the output end of the first drive motor can drive multiple atomizing nozzles to rotate, thereby increasing the spray range and preventing the mist droplets from forming droplets. The rotation of the heating tube can also increase the range of heat dissipation, and the rotation of the mist droplets can achieve the effect of rapid evaporation to form powder. It is easy to use and has a simple structure.

[0027] 4. In summary, by setting the first limit groove, threaded rod, second drive motor, limit plate, rubber ring, lifting block, lifting rod, connecting block and second limit groove, the scraper can be driven to move up and down and rotate through the rotation of the output end of the second drive motor, thereby scraping off the grass jelly concentrate or grass jelly powder on the inner wall of the atomizing drying box cavity. It is easy to use and has a simple structure.

The following embodiments are used to illustrate the present invention.

[0042] like Figure 1 and Figure 2 As shown, a grass jelly powder spray drying device, wherein:

[0043] The invention comprises an atomizing drying box 10, wherein a top plate 12 is fixedly mounted on the top wall of the atomizing drying box 10, a heating pipe 13 is arranged above the top plate 12, and the heating pipe 13 penetrates the top plate 12 and is communicated with the cavity of the atomizing drying box 10;

[0046] It includes a wall scraping device, which includes a lifting ring 20. The upper and lower side walls of the lifting ring 20 are fixedly installed with multiple scrapers 21 in a circular array. A second limiting groove 14 is opened at both the front and rear ends of the inner side wall of the atomizing drying box 10, and a threaded rod 36 is arranged in the cavity of the two second limiting grooves 14.

[0047] It is worth noting that the heating pipe 13 has been disclosed in a new type of airflow spray dryer (202410479230.4), and the heating pipe 13 supplies heat to the heating pipe 18. The heating pipe 13 is a prior art and will not be described in detail here.

[0048] During specific use, the spray device can connect the container of the grass jelly concentrate to the first guide tube 15, and then inject the grass jelly concentrate into the cavity of the second guide tube 16 through the electric pump 22. Due to the water pressure generated by the electric pump 22, the grass jelly concentrate will be sprayed out through the atomizing nozzle 17 and atomized. The heat conduction device can heat the cavity of the atomizing drying box 10 through multiple heating tubes 18, so as to achieve rapid evaporation after the grass jelly concentrate is sprayed out and atomized. During the evaporation of the grass jelly concentrate, it will adhere to the inner side wall of the cavity of the atomizing drying box 10. The lifting ring 20 can move up and down and rotate to drive multiple scrapers 21 to move up and down and rotate, thereby scraping off the grass jelly concentrate on the inner side wall of the cavity of the atomizing drying box 10.

[0049] To sum up, by setting up a spray device, a heat conducting device and a scraping device, the grass jelly concentrate can be sprayed and atomized through the spray device, and then the grass jelly concentrate is evaporated and dried by the heat of the heat conducting device to form a powder. The residue on the inner wall of the atomizing drying box 10 cavity can also be scraped off by the scraping device. Compared with the prior art, it is easy to use and has a simple structure.

[0050] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the left and right ends of the first flow guide tube 15 respectively penetrate the left and right side walls of the atomizing drying box 10, and are fixedly sealed and connected with the penetration points. A third through-hole 31 is provided on the top wall of the first flow guide tube 15, and a flow guide tube 26 is provided on the top wall of the first flow guide tube 15. The positions of the flow guide tube 26 and the third through-hole 31 correspond to each other, and the flow guide tube 26 is connected with the third through-hole 31.

[0051] A first through hole 24 is provided on the bottom wall of the second flow guide tube 16, the lower side wall of the flow guide tube 26 is fixedly connected to the side wall of the first through hole 24, a second through hole 27 is provided on the left and right side walls of the flow guide tube 26, the second through hole 27 is connected to the cavity of the second flow guide tube 16, a connecting plate 29 is fixedly installed on the side wall of the flow guide tube 26, and a plurality of gear teeth 30 are fixedly installed in an annular array on the bottom wall of the connecting plate 29. The electric pump 22 and the first drive motor 25 are both connected to the power supply and the switch by electrical signals.

[0052] During specific use, before work, the staff needs to connect the container storing the grass jelly concentrate to the left and right ends of the first guide tube 15 through pipes, and then the grass jelly concentrate can be sucked into the position of the third perforation 31 from the left and right ends of the first guide tube 15 through two electric pumps 22. Due to the water pressure, the grass jelly concentrate will enter the cavity of the guide tube 26 through the third perforation 31, and then enter the cavity of the second guide tube 16. The second perforation 27 can guide the grass jelly concentrate, and guide part of the grass jelly concentrate to the two ends of the second guide tube 16, so as to facilitate the spraying operation of the atomizing nozzles 17 at the left and right ends.

[0053] In summary, by providing the first guide tube 15, the electric pump 22, the third perforation 31, the guide tube 26, the second guide tube 16, the second perforation 27 and the atomizing nozzle 17, the grass jelly concentrate can be introduced into the cavity of the second guide tube 16 through two electric pumps 22 in cooperation with the first guide tube 15, and then sprayed out through multiple atomizing nozzles 17. By providing multiple atomizing nozzles 17, the spraying amount can be increased. By introducing the grass jelly concentrate from the left and right ends of the first guide tube 15, its flow rate can be increased, thereby increasing work efficiency, being easy to use and having a simple structure.

[0054] like Figure 5 , Figure 7 and Figure 8 As shown, two first fixing plates 23 are arranged above the first guide tube 15, and the bottom walls of the two first fixing plates 23 are hollowed out. A first connecting groove 33 is opened on the side wall of the two first fixing plates 23 close to each other, and the two first connecting grooves 33 are fixedly connected to the side wall of the guide tube 26. The top wall of the connecting plate 29 is in contact with the top wall of the cavity of the two first fixing plates 23. A first driving motor 25 is fixedly installed on the top wall of the cavity of the two first fixing plates 23 at the left and right ends of the guide tube 26, and a spur gear 28 is fixedly installed on the output end of the first driving motor 25. The two spur gears 28 are meshed with the gear teeth 30. A second fixing plate 32 is fixedly installed on the bottom walls of the front and rear ends of the two first fixing plates 23. The side walls of the two second fixing plates 32 close to each other are fixedly connected to the front and rear side walls of the first guide tube 15 respectively. An electric pump 22 is fixedly installed on the side wall of the first guide tube 15 at the left and right ends of the two first fixing plates 23.

[0055] The bottom end of the heating pipe 13 is rotatably connected to the multiple heating pipes 18 and is interconnected with the multiple heating pipes 18. The bottom ends of the corresponding two heating pipes 18 are fixedly connected to the two ends of the top wall of the second guide pipe 16 respectively.

[0056] During specific use, the first fixing plate 23 can limit the first driving motor 25, the second fixing plate 32 and the first connecting groove 33 can seal the first fixing plate 23, and the two first connecting grooves 33 can clamp and limit the guide tube 26. The first fixing plate 23 fits the wall surface of the connecting plate 29, which can further limit the guide tube 26. When the output ends of the two first driving motors 25 rotate, the spur gear 28 can be driven to rotate, and the rotation of the spur gear 28 can drive the connecting plate 29 to rotate through the gear teeth 30 meshing therewith. The rotation of the connecting plate 29 can drive the guide tube 26 to rotate, and the rotation of the guide tube 26 can drive the second guide tube 16 to rotate through the first through-hole 24, thereby driving the multiple atomizing nozzles 17 to rotate, thereby increasing the spray range and preventing liquid from combining.

[0057] During the rotation of the second guide tube 16, the heating tube 18 can be driven to rotate. The heating tube 18 is heated by the heat supply tube 13. Therefore, during the rotation of the heating tube 18, the heat dissipation range is increased at the same time. During the rotation, it comes into contact with the grass jelly concentrate to evaporate quickly. During the rotation of the heating tube 18 and the second guide tube 16, the grass jelly concentrate can also be driven to rotate. During the rotation, the droplets are deformed and the area in contact with the hot air is increased, thereby achieving the effect of rapid evaporation to form powder.

[0058] In summary, by arranging the heating tube 18, the second guide tube 16, the heat supply tube 13, the first drive motor 25, the spur gear 28, the gear teeth 30 and the connecting plate 29, the rotation of the output end of the first drive motor 25 can drive the multiple atomizing nozzles 17 to rotate, thereby increasing the spray range and preventing the mist droplets from forming droplets. The rotation of the heating tube 18 can also increase the range of heat dissipation, and the rotation of the mist droplets can achieve the effect of rapid evaporation to form powder. It is easy to use and has a simple structure.

[0059] like Figure 2 , Fig. 9 As shown in the atomizing drying box 10 , the plurality of scrapers 21 are all triangular in shape, and the side walls of the plurality of scrapers 21 close to the atomizing drying box 10 are all in contact with the inner side wall of the atomizing drying box 10 , and a second connecting groove 35 is provided on the side wall of the lifting ring 20 .

[0060] A second driving motor 37 is fixedly installed on the top wall surface of the cavity of the two second limiting grooves 14, and the two are respectively fixedly installed on the output ends of the two second driving motors 37. A lifting block 40 is threadedly connected to the side wall of the threaded rod 36. A lifting rod 41 is fixedly installed on the side wall where the two lifting blocks 40 are close to each other. The lifting rod 41 is arc-shaped and movably connected to the second connecting groove 35.

[0061] A rubber ring 39 is movably sleeved on the upper and lower ends of the lifting block 40 on the side wall of the threaded rod 36, and a limit plate 38 is threadedly connected to the end of the two rubber rings 39 away from each other on the side wall of the threaded rod 36. The limit plate 38 and the side wall of the lifting block 40 are both in contact with the inner side wall of the second limit groove 14, and the side wall surfaces of the two limit plates 38 close to each other are respectively in contact with the side wall surfaces of the two rubber rings 39 away from each other. Two first limit grooves 11 are provided on the side wall of the threaded rod 36, and two connecting blocks 42 are fixedly installed in the cavity of the rubber ring 39. The two connecting blocks 42 are respectively movably installed in the cavity of the two first limit grooves 11, and the side walls of the multiple rubber rings 39 are in contact with the side wall of the lifting ring 20. The second drive motor 37 is connected to the power supply and the switch by electrical signals.

[0062] In specific use, when the output end of the second driving motor 37 rotates, the threaded rod 36 can be driven to rotate, and the rotation of the threaded rod 36 can drive the lifting block 40 threadedly connected thereto to move up and down. The lifting block 40 cannot rotate due to the limit of the second limiting groove 14. When the lifting block 40 moves up and down, it can drive the lifting rod 41 to move up and down, and then drive the lifting ring 20 to move up and down through the second connecting groove 35. When the threaded rod 36 rotates, the rubber ring 39 can be driven to rotate through the connection between the connecting block 42 and the first limiting groove 11. The rotation of the rubber ring 39 can drive the lifting ring 20 to rotate by fitting with the side wall of the lifting ring 20, and the rotation of the lifting ring 20 can drive the scraper 21 to rotate, so that the scraper 21 can move up and down to increase the application range when it rotates to scrape off the residue on the inner wall of the atomizing drying box 10 cavity. When the threaded rod 36 rotates, it can drive the two limit plates 38 to move up and down. The two limit plates 38 cannot rotate due to the limitation of the second limit groove 14. Therefore, the up and down movement of the gear teeth 30 and the limit plates 38 can drive the rubber ring 39 to move up and down.

[0063] To sum up, by setting the first limit groove 11, threaded rod 36, second drive motor 37, limit plate 38, rubber ring 39, lifting block 40, lifting rod 41, connecting block 42 and second limit groove 14, the scraper 21 can be driven to move up and down and rotate through the rotation of the output end of the second drive motor 37, thereby scraping off the grass jelly concentrate or grass jelly powder on the inner wall of the atomizing drying box 10. It is easy to use and has a simple structure.
