Description

Technical Field

[0001] The invention relates to the technical field of anthocyanidin freeze-dried powder, in particular to an industrial production device for anthocyanidin freeze-dried powder. Background Art

[0002] Anthocyanins are water-soluble natural pigments widely found in plants, fruits, vegetables, and flowers. There are more than 20 known anthocyanins. Anthocyanins in their natural state exist in the form of glycosides, called anthocyanins. There are very few free anthocyanins. Anthocyanins are mainly used for food coloring, and can also be used in dyes, medicines, cosmetics and many other fields. Freeze-dried powder is a way to purify and dry anthocyanins in solution by freezing and water sublimation.

[0003] The existing patent (Announcement No.: CN114870961B) discloses an industrial production device for freeze-dried black wolfberry anthocyanin powder, which includes a shell, multiple transmission devices, multiple rotating devices and a partition plate; the shell is provided with a partition plate that slides with the shell, and the shell is provided with multiple vertically arranged transmission devices and rotating devices, and each transmission device passes through the partition plate, and one end of each rotating device is arranged at the lower end of the partition plate. When the raw materials are minced, the present invention pushes the materials toward the reamer through the squeezing force between the materials, thereby reducing the occurrence of incomplete mincing. After the materials are minced, the partition plate falls back to the bottom to prepare for the next mincing, and the minced raw materials can also be screened to avoid large particles affecting the quality of the finished product and save time.

The side walls of each group of gears 304 are respectively fixedly connected with a group of crushing rollers 306. The outer walls of each group of crushing rollers 306 are respectively fixedly connected with multiple groups of blades. The inner wall of the outer box body 201 is rotatably connected with multiple groups of connecting shafts 307. One end of the connecting shaft 307 is provided with a square groove. The other end of the multiple groups of connecting shafts 307 is provided with a pulley group 310. The inner wall of the outer box body 201 is fixedly connected with a second motor 311. The output end of the second motor 311 is connected to the input end of the pulley group 310. The top of the outer box body 201 is hinged with an upper cover. 207, the side wall of the outer box body 201 is connected to a discharge pipe 208, the end of the discharge pipe 208 is hinged with a sealing cover 209, the bottom end of the inner wall of the outer box body 201 is rotatably connected to an auger 210, the side wall of the outer box body 201 is fixedly connected to a first motor 211, the output end of the first motor 211 is fixedly connected to one end of the auger 210, the outer walls of the multiple groups of connecting pipes 204 on one side are respectively fixedly sleeved with toothed discs 212, the inner wall of the outer box body 201 is fixedly connected to multiple groups of racks 213, each group of racks 213 is respectively meshed with a group of toothed discs 212, and the multiple groups of connecting pipes on the other side are respectively fixedly sleeved with toothed discs 212. The outer wall of 204 is provided with a connecting frame 308, and the top of the connecting frame 308 is fixedly connected with two groups of hydraulic rods 309. The outer wall of the hydraulic rod 309 is fixedly connected to the inner wall of the outer box body 201, and then the hydraulic rod 309 contracts to drive the connecting frame 308 to reset, so that the slider 103 slides upward and resets. During this process, the toothed disc 212 contacts the rack 213 again, so that the toothed disc 212 rotates in the opposite direction, so that the screen frame 301 and the discharge trough 205 rotate in the opposite direction and reset, and the connecting shaft 307 is disconnected from the rotating shaft 302, and the connecting pipe 204 is aligned with the synchronous pipe again.

[0022] The upper cover 207 is opened, the lock is released, the screen frame 301 is turned over, and the anthocyanin solution is added into the discharge trough 205. The screen frame 301 is turned over and the lock is locked, so that the screen frame 301 and the discharge trough 205 cannot be separated. The upper cover 207 is closed, and the refrigeration equipment is connected to the outer box 201 through the vent pipe 206. The cold air enters the connecting pipe 204 through the vent pipe 206 and finally enters the discharge trough 205, so that the anthocyanin solution in the discharge trough 205 is quickly frozen. After the anthocyanin solution is completely frozen, the connecting frame 308 is pushed by the hydraulic rod 309, so that the connecting frame 308 drives the connecting pipe 204 to descend, thereby making the connecting pipe 20 4 is separated from the vent pipe 206, the connecting pipe 204 drives the discharge and the screen frame 301 to descend, and makes the guide block 203 slide downward inside the slide groove 202. During this process, the toothed disc 212 moves downward, and the toothed disc 212 rotates the connecting pipe 204 through the meshing action between the toothed disc 212 and the rack 213, so that the connecting pipe 204 drives the screen frame 301 and the discharge groove 205 to rotate 180 degrees, and as the guide block 203 continues to slide downward, the toothed disc 212 is separated from the rack 213, and then the guide block 203 continues to slide downward, so that the end of the rotating shaft 302 located outside the screen frame 301 slides into the square groove at one end of the connecting shaft 307, so that the connecting shaft 307 is rotated in the groove. During the rotation, the rotating shaft 302 is driven to rotate, and the pulley set 310 is driven by the second motor 311, so as to transmit power to the rotating shaft 302, so that the rotating shaft 302 rotates. During the rotation, the rotating shaft 302 drives the turntable 303 to rotate, and the turntable 303 drives the multiple sets of gears 304 to rotate, so that the multiple sets of crushing rollers 306 rotate. During the simultaneous revolution of the multiple sets of crushing rollers 306, due to the meshing action of the gears 304 and the gear ring 305, the multiple sets of gears 304 rotate themselves, so that the multiple sets of crushing rollers 306 rotate themselves during the revolution. In addition, since the screen frame 301 and the discharge trough 205 rotate 180 degrees, the frozen anthocyanin solution falls into the screen frame 301, so that the crushing rollers 306 rotate. 06 The frozen anthocyanin solution is broken into small pieces, thereby increasing the surface area of ​​the anthocyanin solution after being frozen. The pieces are then connected to the ventilation pipe 206 through an air pump, and the interior of the outer box 201 is evacuated. The negative pressure inside the outer box 201 makes the upper cover 207 and the sealing cover 209 fit tightly to the top of the outer box 201 and the end of the discharge port. The electric heating wire inside the sieve frame 301 is then used to generate heat, thereby sublimating the water inside the frozen anthocyanin solution. The freeze-dried powder then falls from the sieve hole into the powder sieve structure. After being sieved by the powder sieve mechanism 4, the auger 210 is driven by the first motor 211 to rotate and the freeze-dried powder is discharged from the outer box 201.

[0023] Please refer to Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 The inner wall of the outer box body 201 is slidably provided with a powder screening mechanism 4, and the powder screening mechanism 4 includes a material blocking frame 401, and the inner wall of the material blocking frame 401 is fixedly connected with multiple groups of convex strips 402, and the outer wall of the multiple groups of convex strips 402 is slidably connected with a support frame 403, and the top of the support frame 403 is fixedly connected with multiple groups of top material plates 404, and the outer wall of the support frame 403 is fixedly connected to the bottom edge of the soft filter screen 412, and the top edge of the soft filter screen 412 is fixedly connected to the bottom end of the material blocking frame 401, and the side wall of the material blocking frame 401 is hinged with multiple groups of rotating arms 409, and the bottom end of each group of rotating arms 409 is fixedly connected with A group of slapping plates 410, each group of rotating arms 409 is provided with a torsion spring at the connection with the material blocking frame 401, a group of protrusions 411 are respectively provided under each group of rotating arms 409, and multiple groups of protrusions 411 are fixedly connected to the inner wall of the outer box body 201, and multiple groups of sliding sleeves 408 are fixedly connected to the top of the material blocking frame 401. A group of sliding rods 407 are slidingly sleeved on the inner wall of each group of sliding sleeves 408, and a group of pressing rods 406 are fixedly connected to the outer wall of each group of sliding rods 407. An eccentric disk 405 is rotatably connected to the top of each group of pressing rods 406, and multiple groups of eccentric disks 405 are connected to the pulley group 310.

[0024] During the rotation of the pulley group 310, the pulley group 310 drives the eccentric disk 405 to rotate, so that the eccentric disk 405 continuously pushes and pulls the lower pressure rod 406 up and down, so that the lower pressure rod 406 drives the sliding rod 407 to move up and down, so that the lower pressure rod 406 pushes and pulls the sliding sleeve 408 up and down, thereby driving the material blocking frame 401 to continuously move up and down. During the downward movement of the material blocking frame 401, the soft filter screen 412 is relaxed, so that the freeze-dried powder on the soft filter screen 412 falls downward under the action of gravity, and the freeze-dried powder is blocked by the top plate 404, so that the freeze-dried powder at the bottom is turned to the top, and the soft filter screen 412 is tightened during the upward movement of the material blocking frame 401, so that the freeze-dried powder is Lifting upward, the freeze-dried powder is blocked by the top plate 404 again, so that the freeze-dried powder above is blocked to the bottom, which plays a role in constantly stirring the freeze-dried powder. During the up and down reciprocating motion of the blocking frame 401, the rotating arm 409 is driven to move up and down. During the upward movement of the rotating arm 409, it contacts the protrusion 411, so that the rotating arm 409 is blocked by the protrusion 411 and flipped, and the torsion spring is twisted. After the rotating arm 409 slides over the protrusion 411, the rotating arm 409 flips back and resets under the rebound of the torsion spring, so that the rotating arm 409 drives the slapping plate 410 to contact the soft filter screen 412, thereby slapping the soft filter screen 412, so that the freeze-dried powder continuously falls from the soft filter screen 412 to the bottom end of the inner wall of the outer box body 201.
