[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , An embodiment provided by the present invention: A selenium-rich barley composite green juice powder production device, including a grinding cylinder 1, a feed hopper 2 is installed at the top of the grinding cylinder 1, a screening box 9 is installed at the bottom of the grinding cylinder 1, a through groove 11 is opened on the front of the screening box 9, a connection and fixing module is installed inside the screening box 9, and a screening component is installed on the screening box 9 through the connection and fixing module. The screening component is used for screening the ground composite green juice powder; The connection and fixing module includes a connection component and a fixing component. The connection component is used to install the screening component inside the screening box 9, and the fixing component is used to fix the screening component. The connection component includes a slide rail 12 and a slide bar 13. Slide rails 12 are symmetrically installed on the inner side walls of the screening box 9, and the installation height of the slide rails 12 is between the upper and lower edge heights of the through groove 11. A slide bar 13 is slidably installed inside the slide rail 12, and the side profile of the slide bar 13 is T-shaped. The screening component includes an installation frame 14. The screening box 9 installs an installation frame 14 through the slide rail 12 and the slide bar 13, and the outer walls on both sides of the installation frame 14 are connected to the slide bar 13. A baffle 15 is installed on the front of the installation frame 14, and the size of the baffle 15 matches that of the through groove 11. The fixing component includes a threaded groove 16, a screw 17, a stop block 18 and a rubber pad 19. Threaded grooves 16 are symmetrically opened on the inner top wall and bottom wall of the through groove 11. A screw 17 is movably installed inside the threaded groove 16. A stop block 18 is installed at the top of the screw 17, and a rubber pad 19 is installed on the back of the stop block 18, and the rubber pad 19 abuts against the front of the baffle 15.

[0026] Further, the selenium-rich barley composite green juice freeze-dried blocks are put into the interior of the grinding cylinder 1 through the feed hopper 2 and ground inside the grinding cylinder 1. The powder after grinding completes the screening process inside the screening box 9. When it is necessary to take out or replace the screen, the staff can realize the taking out, installation and fixing of the screen through the connection and fixing module; when it is necessary to take out the screen, the staff can rotate the screw rod 17 to completely withdraw the screw rod 17 from the interior of the thread groove 16. At this time, the stopper 18 has separated from the screw rod 17 and no longer restricts the baffle 15. Drag the baffle 15 through the handle to make the baffle 15 drive the screen powder assembly to withdraw from the through groove 11 of the screening box 9; when the screen powder assembly is fixedly installed inside the screening box 9, the slide bars 13 on both sides of the installation frame 14 are correspondingly clamped into the tracks of the slide rails 12, and then push the handle inward to drive the baffle 15 to slide inward from the through groove 11 until the slide bars 13 on both sides of the installation frame 14 slide into the deepest part of the slide rails 12. At this time, the staff rotates the screw rod 17 and inserts it into the interior of the thread groove 16 at an appropriate position, and then rotates the screw rod 17 until the stopper 18 and the rubber pad 19 exert a pressing force on the baffle 15 to fix the baffle 15, thereby realizing the fixing of the screen powder assembly; through the connection and fixing module, it is convenient for the staff to take out and fixedly install the screen powder assembly, thereby facilitating the treatment of the particles remaining on the screen and the replacement of the screen.

[0027] Please refer to Figure 1 and Figure 3 As shown in and, an embodiment provided by the present invention: A selenium-rich barley composite green juice powder production device, the screen powder assembly further includes guide rods 20, guide blocks 22, a screen frame 23 and a sieve mesh 25. Guide rods 20 are symmetrically installed on the top of the installation frame 14. Guide blocks 22 are slidably installed on the outer sides of the guide rods 20. A screen frame 23 is installed on the inner sides of the symmetrical guide blocks 22. A sieve mesh 25 is installed at the inner bottom end of the screen frame 23. The screen powder assembly further includes support springs 21 and vibration motors 24. Support springs 21 are symmetrically installed on the top of the installation frame 14, and the support springs 21 are located on the outer sides of the guide rods 20. The bottom of the guide block 22 is connected to the top of the support spring 21. A vibration motor 24 is installed inside the frame of the screen frame 23.

[0028] Further, the powder falling from the grinding cylinder 1 slides along the first diversion hopper 10 and lands on the sieve mesh 25. The vibration action formed by the mutual cooperation of the vibration motor 24 and the support spring 21 can make the guide block 22 and the screen frame 23 vibrate up and down along the guide rods 20. The up and down vibration of the screen frame 23 drives the materials on the sieve mesh 25 to jump up and down, avoiding the accumulation of materials on the sieve mesh 25 from affecting the screening effect, and at the same time can also accelerate the screening rate.

[0029] Please refer to Figure 1, an embodiment provided by the present invention: a production device for selenium-rich barley composite green juice powder. A grinding and pulverizing assembly is installed inside the grinding cylinder 1, and the grinding and pulverizing assembly is used for pulverizing and grinding materials. The grinding and pulverizing assembly includes a chopping knife 6, an annular grinding block 5, and a grinding frustum 7. A driving motor 3 is installed at the center of the top of the grinding cylinder 1, and the output end of the driving motor 3 penetrates the inner top wall of the grinding cylinder 1. The output end of the driving motor 3 is installed with a rotating shaft 4. The outer circumferential surface of the rotating shaft 4 is installed with a chopping knife 6. The inner wall of the grinding cylinder 1 is installed with an annular grinding block 5, and the annular grinding block 5 is located below the chopping knife 6. The outer circumferential surface of the rotating shaft 4 is installed with a grinding frustum 7, and the grinding frustum 7 is located below the chopping knife 6. The opposite surfaces of the grinding frustum 7 and the annular grinding block 5 are evenly installed with grinding protrusions. The bottom plate of the grinding cylinder 1 is a filter plate 8, and a first diversion hopper 10 is installed at the bottom of the filter plate 8 of the grinding cylinder 1, and the first diversion hopper 10 is located inside the screening box 9.

[0030] Furthermore, when the production device for selenium-rich barley composite green juice powder works, the driving motor 3 drives the rotating shaft 4 to rotate, so that the chopping knife 6 and the grinding frustum 7 installed on the rotating shaft 4 rotate. After the selenium-rich barley composite green juice freeze-dried blocks are put into the inside of the grinding cylinder 1 from the feed hopper 2, the rotating chopping knife 6 first cuts the relatively large freeze-dried solids, and makes them become relatively small freeze-dried solids under the shearing action of the chopping knife 6. The relatively small freeze-dried solids fall between the grinding frustum 7 and the annular grinding block 5, and the freeze-dried solids are ground through the extrusion, sliding and rolling movements of the grinding protrusions on the rotating grinding frustum 7 and the annular grinding block 5 until the ground material particles are smaller than the pore diameter on the filter plate 8 and fall through the pore diameter on the filter plate 8; in addition, the pore diameter of the sieve mesh 25 is smaller than the pore diameter of the filter plate 8; by first preliminarily pulverizing the freeze-dried solid blocks with the chopping knife 6, the materials can be better ground into fine powder, and at the same time, the grinding rate can be accelerated.

[0031] Please refer to Figure 1 and Figure 5An embodiment of the present invention is a production device for selenium-enriched barley composite green juice powder, wherein a second guide hopper 26 is installed on the inner wall of the screening box 9, and the second guide hopper 26 is located below the slide rail 12, and the second guide hopper 26 passes through the bottom center of the screening box 9, and the bottom edge of the screening box 9 is symmetrically installed with support legs 40, and the bottom of the second guide hopper 26 is connected to a first discharge pipe 27, and the inner wall of the first discharge pipe 27 is symmetrically provided with limiting grooves 28, and a second discharge pipe 30 is movably installed inside the first discharge pipe 27, and an adjustment component is arranged inside the first discharge pipe 27, and the adjustment component is used to adjust the length of the second discharge pipe 30 extending out of the first discharge pipe 27, and the second discharge pipe 27 is provided with a plurality of adjustment components. The outer surface of the tube 30 is symmetrically installed with limit strips 29, and the limit strips 29 are slidably connected with the limit grooves 28. The adjustment component includes a combined rack 31 and a toggle gear 33. The outer surface of one group of limit strips 29 of the second discharge tube 30 is installed with a combined rack 31 on one side surface. The outer surface of the first discharge tube 27 is provided with a surface groove 32, and the surface groove 32 is connected with one group of limit grooves 28. The inner wall of the surface groove 32 is movably installed with a toggle gear 33, and the toggle gear 33 is meshed with the convex teeth of the combined rack 31. The outer surfaces of the second discharge tube 30 and the limit strips 29 are installed with dust covers 34, and the bottom end height of the dust cover 34 is higher than the bottom end height of the second discharge tube 30.

[0032] Furthermore, the powder screened by the powder screening assembly enters the discharge pipe under the drainage action of the second guide bucket 26, and finally falls from the discharge pipe; when the green juice powder after grinding and screening is loaded into the packaging bag or packaging bottle through the discharge pipe, the staff can use their fingers to move the toggle gear 33 in the surface groove 32, so that the combined rack 31 drives the second discharge pipe 30 to extend or retract from the inside of the first discharge pipe 27 under the meshing transmission action of the toggle gear 33, so that the overall length of the discharge pipe can adapt to the packaging bottle or packaging bag, until the dust cover 34 covers the opening part of the packaging bottle or packaging bag, so as to avoid the flying of powder of selenium-rich barley composite green juice powder during the discharging and packaging process; in addition, the mutual cooperation of the limit groove 28 and the limit bar 29 can limit the moving trajectory of the second discharge pipe 30, ensuring that the meshing transmission can be completed between the toggle gear 33 and the combined rack 31.

[0033] See also Figure 1 and Figure 6 An embodiment of the present invention is a production device for selenium-enriched barley composite green juice powder, wherein a heating box 35 is installed on the outer wall of a grinding cylinder 1, three sets of electric heating networks 36 are arranged inside the heating box 35, an air inlet pipe 37 is connected to the top of the heating box 35, an induced draft fan 38 is installed on the top of the grinding cylinder 1, an input end of the induced draft fan 38 is connected to the air inlet pipe 37, a porous plate 39 is inlaid on the inner top wall of the grinding cylinder 1, and the porous plate 39 is connected to the output end of the induced draft fan 38 through a pipeline.

[0034] Further, during the process of crushing and grinding the freeze-dried blocks in the grinding cylinder 1, if some of the freeze-dried blocks put into the interior of the grinding cylinder 1 are damp, the crushed powder may agglomerate. The electric heating grid 36 inside the heating box 35 emits heat, and the induced draft fan 38 sucks the heat inside the heating box 35 through the air inlet pipe 37 and sends the hot air into the interior of the grinding cylinder 1 through the pipe via the perforated plate 39. After the hot air enters the perforated plate 39, it accelerates and contacts the materials inside the grinding cylinder 1 more quickly. By maintaining the hot air introduced by the induced draft fan 38, the high temperature inside the grinding cylinder 1 can be maintained, which has a certain drying effect on the internal materials and avoids the situation where the damp materials inside the grinding cylinder 1 agglomerate after being crushed.

[0035] Further, a method for using a production device for selenium-rich barley composite green juice powder is as follows: S1. Put the selenium-rich barley composite green juice freeze-dried blocks into the interior of the grinding cylinder 1 through the feed hopper 2, and the grinding and crushing assembly crushes and grinds the materials inside the grinding cylinder 1; S2. After the crushed and ground materials fall from the grinding cylinder 1, they are processed by the powder screening assembly, and the powder screening assembly obtains powder particles with higher precision through the screen mesh; S3. The staff can adjust the length of the second discharge pipe 30 extending out of the first discharge pipe 27 through the adjustment assembly, thereby adjusting the length of the overall discharge pipe, so that the dust-proof cover 34 can block the opening of the packaged item, thereby reducing the powder flying situation during the powder collection process.

[0036] In S1, the following steps are further included: S11. During the grinding of the materials, the induced draft fan 38 sends the heat of the heating box 35 into the interior of the grinding cylinder 1, so that the interior of the grinding cylinder 1 maintains a high temperature, which has a certain drying effect on the materials inside the grinding cylinder 1 and avoids the situation where the damp materials inside the grinding cylinder 1 agglomerate after being crushed; In S2, the following steps are further included: S21. Through the connection and fixing module, it is convenient for the staff to disassemble the powder screening assembly from the screening box 9, and at the same time, it is also convenient for the installation of the powder screening assembly, thereby facilitating the staff to handle the particles remaining on the screen mesh and replace the screen mesh.

[0037] Working principle: Put the selenium-rich barley composite green juice freeze-dried blocks into the interior of the grinding cylinder 1 through the feed hopper 2 and grind them inside the grinding cylinder 1. The driving motor 3 drives the chopping knife 6 and the grinding table 7 to rotate, so that the materials complete grinding through the sliding and rolling movements of the chopping knife 6 for preliminary crushing and then through the grinding table 7 and the annular grinding block 5. Through the preliminary crushing of the freeze-dried solid by the chopping knife 6, the grinding efficiency can be increased while improving the precision of the grinding particles; In the process of crushing and grinding the material, the electric heating network 36 inside the heating box 35 emits heat, the induced draft fan 38 absorbs the heat in the heating box 35 through the air inlet pipe 37, and sends the hot air through the pipeline through the porous plate 39 into the interior of the grinding cylinder 1. By maintaining the hot air introduced by the induced draft fan 38, the high temperature inside the grinding cylinder 1 can be maintained, which has a certain drying effect on the internal material, and avoids the situation that the damp material inside the grinding cylinder 1 is agglomerated after being crushed; The ground material falls from the filter plate 8 and falls onto the screen 25 along the first guide bucket 10. The screen frame 23 drives the material on the screen 25 to jump up and down under the action of the vibration motor 24 and the support spring 21, so as to avoid the accumulation of material on the screen 25 affecting the screening effect and speed up the powder screening rate. If the particles with larger particle sizes left on the sieve 25 need to be ground again, or if the sieve 25 in the powder screening assembly needs to be replaced, the powder screening assembly needs to be taken out of the screening box 9, and the screw 17 is rotated to make it withdraw from the thread groove 16, and then the baffle 15 is pulled outward by the handle to drive the powder screening assembly to withdraw from the screening box 9; when installing the powder screening assembly, the slide bar 13 is aligned with the slide rail 12, and the baffle 15 is pushed inward until the installation frame 14 reaches the deepest part of the screening box 9. At this time, the screw 17 is rotated and inserted into the interior of the thread groove 16, so that the block 18 and the rubber pad 19 generate abutting pressure on the baffle 15, thereby fixing the powder screening assembly; The powder sieved by the powder sieving assembly enters the discharge pipe under the drainage action of the second guide bucket 26.
