Description

Technical Field

[0002] In the current breeding environment, the high-fat and high-protein feeds fed to animals contain more oil, which is the most easily oxidized and rancid substance. In terms of price and performance, tea polyphenols are a type of natural phenolic antioxidant with high cost performance, green and safe, with excellent antioxidant effect in vivo, and better effect when combined with other antioxidants. The antioxidant capacity of tea polyphenols is 4 to 6 times that of industrial antioxidants such as ethoxyquinoline, and more than 5 times that of vitamin C and vitamin E. Current medical research has confirmed that tea polyphenols have antioxidant, fat metabolism regulation, antibacterial and antiviral, anti-tumor and anti-mutation functions; they have the ability to bind to proteins and have a certain protective effect on proteins; they have an effect on improving starch digestibility, promoting growth, and increasing daily weight gain.

[0003] When preparing tea polyphenol compound feed antioxidant, it is necessary to mix synergist, emulsifier, dispersant and other ingredients with tea polyphenol evenly and then sieve to finally make tea polyphenol compound feed antioxidant. After the various raw materials are stirred in the mixing barrel, the mixed raw materials need to be filtered. Since the raw materials in the antioxidant are basically solid powder and crystal powder, during the sieving process, the sieving action causes the powder mixture to move, which will cause part of the powder mixture to float in the air, making it difficult to pass through the sieve, and further making it difficult to sieve all the powder mixture in the sieving process, which not only prolongs the sieving time, but also easily causes residue on the sieve. Therefore, a tea polyphenol compound feed antioxidant preparation device and a preparation method thereof are proposed. Summary of the invention

[0041] Embodiment 1

[0042] Reference Figure 1-Figure 8 , which is an embodiment of the present invention, provides a tea polyphenol compound feed antioxidant preparation device, comprising: a preparation unit 100, a compression unit 200 and a screening unit 300;

[0043] The preparation unit 100 includes a processing box 101 and a servo motor 102 fixedly installed on the top of the processing box 101, a feed pipe 103 penetrating the top of the processing box 101 is fixedly connected to the top of the processing box 101, a discharge hopper 104 penetrating the bottom of the processing box 101 is fixedly connected to the bottom of the processing box 101, three fixed columns are fixedly connected to the top of the inner wall of the processing box 101, and a mixing barrel 105 whose bottom end is not sealed is commonly fixedly connected to the bottom of the three fixed columns, the bottom end of the feed pipe 103 is connected to the mixing barrel 105, and the output end of the servo motor 102 penetrates the processing box 101 and is fixedly connected to a stirring rod 106 penetrating the mixing barrel 105;

[0044] The compression unit 200 includes a reset rod 201 rotatably connected to the top of the processing box 101, the reset rod 201 penetrates the top of the processing box 101 and is fixedly connected to a driving rod 202, a rod surface of the driving rod 202 is fixedly sleeved with a flywheel 203, the driving rod 202 penetrates the mixing barrel 105 and is threadedly sleeved with a disc 204, the stirring rod 106 vertically penetrates the disc 204, and the compression unit 200 also includes a driving member 205 for driving the flywheel 203 to rotate;

[0045] The screening unit 300 includes two fixed rods 301 fixedly connected to the inner wall of the processing box 101, a first screen plate 302 is slidably sleeved between the two fixed rods 301, two first springs 303 sleeved on the two fixed rods 301 are fixedly connected to both sides of the first screen plate 302, a second screen plate 304 is slidably arranged on the top of the first screen plate 302, and the screening unit 300 also includes a trigger assembly 305 for moving the second screen plate 304.

[0046] The height of the disc 204 is higher than the height of the bottom opening of the feed pipe 103, and the disc 204 is in sealed contact with the inner wall of the mixing barrel 105. The raw materials can be transported to the mixing barrel 105 through the feed pipe 103. The first group of raw materials added to the mixing barrel 105 includes part of the carrier and the synergist, the emulsifier, and the dispersant. The carrier is silicon dioxide, the synergist is selected from citric acid and calcium dihydrogen phosphate, the emulsifier is selected from one or two of monoglyceride or diglyceride, and the dispersant is selected from sodium sulfate. The bottom end of the mixing barrel 105 is not closed, and the bottom end of the mixing barrel 105 is in contact with the second sieve plate 304. The sieve holes of the second sieve plate 304 and the first sieve plate 302 are distributed in the same manner, and the sieve holes of the second sieve plate 304 and the first sieve plate 302 are staggered so that the raw materials in the mixing barrel 105 will not pass through the second sieve plate 304 and the first sieve plate 302. The thickness of the second sieve plate 304 is relatively thin and does not exceed three millimeters to reduce the residue of the raw materials.

[0047] The bottom end of the stirring rod 106 is fixedly connected with a plurality of stirring blades distributed in an annular shape. The stirring blades are obliquely distributed on the stirring rod 106, and the stirring blades themselves are curved. The stirring blades are located at the bottom of the mixing barrel 105 and leave a gap with the second sieve plate 304. When the servo motor 102 drives the stirring rod 106 to rotate forward, the stirring rod 106 stirs and mixes the raw materials in the mixing barrel 105 through the stirring blades. The plurality of stirring blades can generate an upward airflow, so that the powdered raw materials are stirred by the air in the mixing barrel 105, thereby accelerating the mixing of various raw materials. The mixing of materials and the improvement of the mixing effect are achieved. When the servo motor 102 rotates forward, the driving member 205 will not drive the flywheel 203 to rotate. When the servo motor 102 drives the stirring rod 106 to rotate in the reverse direction, the stirring blade rotates in the reverse direction and generates a downward airflow. At this time, the driving member 205 drives the flywheel 203 to rotate, and the flywheel 203 rotates by driving the driving rod 202. One end of the driving rod 202 located in the mixing barrel 105 is provided with a thread, and the driving rod 202 can make the disc 204 descend along the inner wall of the mixing barrel 105;

[0048] At this time, the raw materials are located at the bottom of the disc 204. As the disc 204 descends, the space for mixing the raw materials in the mixing barrel 105 is reduced. During the descent process, the disc 204 drives the second sieve plate 304 to move through the trigger assembly 305, so that the sieve holes of the second sieve plate 304 are vertically aligned with the sieve holes of the first sieve plate 302. At this time, the mixed raw materials can pass through the sieve holes of the second sieve plate 304 and the first sieve plate 302 in sequence, so that the qualified powder mixture is sieved. During the continuous stirring process of the stirring rod 106, the disc 204 will continue to descend and scrape off the materials attached to the inner wall of the mixing barrel 105. The disc 204 continuously reduces the mixing space of the mixing barrel 105 to reduce the space for the powder raw materials to move, and the downward wind field generated by the stirring blade enables the raw materials to be quickly sieved.

[0049] The maximum height to which the disc 204 can descend does not exceed the height of the bottom end of the driving rod 202 to prevent the disc 204 from colliding with the stirring blade. A space is left between the disc 204 and the second sieve plate 304 to facilitate the stirring blade to generate wind force, so that the servo motor 102 can automatically complete the sieving after the mixing is completed. When the sieving is completed, the servo motor 102 is turned off and the reset rod 201 is manually rotated to make the driving rod 202 rotate in the opposite direction and drive the disc 204 to rise and reset. When the disc 204 rises and resets, the trigger component 305 automatically pushes the second sieve plate 304 to move, so that the second sieve plate 30 The sieve holes of 4 are staggered with the sieve holes of the first sieve plate 302 to facilitate the second preparation. The discharge hopper 104 is located below the first sieve plate 302. The screened raw materials will fall into the discharge hopper 104. The discharge hopper 104 is provided with a valve to facilitate discharge. When performing the second preparation, the remaining carrier and tea polyphenols need to be added to the mixing barrel 105 through the feed pipe 103. When the second group of raw materials are mixed and screened, the first group of raw materials and the second group of raw materials are added to the mixing barrel 105 again through the feed pipe 103 according to the proportion, and then mixed and screened again to finally make the tea polyphenol compound feed antioxidant.

[0050] Specifically, the driving member 205 includes a driving disk 2051 fixedly sleeved on the stirring rod 106, and a plurality of mounting grooves are provided on the outer wall of the driving disk 2051, and tooth blocks 2052 are slidably provided in some of the mounting grooves. The top of the driving disk 2051 is fixedly connected to a fixing plate 2053 by bolts.

[0051] A plurality of mounting grooves are distributed in an annular shape on the side wall of the driving disk 2051. The driving disk 2051 can slide and install different numbers of tooth blocks 2052 through the mounting grooves. The fixing plate 2053 can be fixed on the driving disk 2051 by bolts. The top of the tooth block 2052 is limited by the fixing plate 2053 to ensure that the tooth block 2052 will not fall off from the mounting groove during the rotation of the driving disk 2051. During the rotation of the driving disk 2051, the tooth block 2052 will mesh with the tooth ring on the outer side of the flywheel 203 and drive the tooth ring of the flywheel 203 to rotate. Different numbers of tooth blocks 2052 can drive the tooth ring of the flywheel 203 to rotate at different angles. When a tooth block 2052 is provided in each mounting groove, when the driving disk 2051 rotates one circle, the tooth ring of the flywheel 203 can also rotate one circle.

[0052] The number of tooth blocks 2052 is proportional to the rotation angle of the tooth ring of the flywheel 203. When there are more raw materials, the number of tooth blocks 2052 is reduced, so that the flywheel 203 drives the driving rod 202 to rotate slightly to slow down the descending speed of the disc 204, thereby providing sufficient sieving time for the raw materials. When the amount of raw materials is small, the number of tooth blocks 2052 is increased, so that the flywheel 203 drives the driving rod 202 to rotate significantly to accelerate the descending speed of the disc 204, thereby quickly compressing the mixing space and For fast screening of a small amount of raw materials, the flywheel 203 has a ratchet structure inside, so that the toothed ring and the inner core ring of the flywheel 203 can only rotate synchronously in one direction. When the servo motor 102 rotates forward, the toothed block 2052 drives the toothed ring of the flywheel 203 to rotate, while the inner core ring of the flywheel 203 does not rotate. When the servo motor 102 rotates reversely, the toothed ring drives the inner core ring to rotate synchronously. The inner core ring of the flywheel 203 is fixedly sleeved on the driving rod 202, thereby driving the driving rod 202 to rotate through the flywheel 203.

[0053] More specifically, the trigger assembly 305 includes a rectangular frame 3051 fixedly connected to the top of the second sieve plate 304, a connecting plate 3052 is slidably arranged in the rectangular frame 3051, a plurality of second springs 3053 are fixedly connected to the side wall of the connecting plate 3052, one end of the connecting plate 3052 slides through the mixing barrel 105 and is fixedly connected to a vertical plate 3054, and a vertical groove that fits the vertical plate 3054 is opened on the inner wall of the mixing barrel 105.

[0054] The vertical plate 3054 is slidably arranged in the vertical slot, and the vertical plate 3054 protrudes from the vertical slot of the mixing barrel 105. The height of the bottom end of the vertical plate 3054 is lower than the height of the bottom end of the driving rod 202. The end of the second spring 3053 away from the connecting plate 3052 contacts the inner wall of the processing box 101. The second spring 3053 limits the connecting plate 3052 so that the vertical plate 3054 will not move completely into the vertical slot of the mixing barrel 105. The vertical slot can completely accommodate the vertical plate 3054. When the disc 204 is located above the opening at the bottom end of the feeding pipe 103, The mixing space in the mixing barrel 105 reaches the maximum, so that the raw materials can be stirred by the stirring rod 106, and the mixing of the raw materials is accelerated by the fluidity of the air. When the servo motor 102 rotates in the opposite direction, the disc 204 begins to descend and compress the mixing space. When the disc 204 contacts the vertical plate 3054, the raw materials are screened. The upper and lower edges of the vertical plate 3054 close to the stirring rod 106 are both provided with smooth chamfers. When the disc 204 contacts the chamfers at the top of the vertical plate 3054, the disc 204 squeezes the vertical plate 3054 into the vertical groove.

[0055] At this time, the vertical plate 3054 pushes the connecting plate 3052 in the direction of the second spring 3053, so that the connecting plate 3052 squeezes the second spring 3052. At the same time, the bottom end of the connecting plate 3052 pulls the second sieve plate 304 in the direction of the second spring 3053 through the rectangular frame 3051, so that the sieve holes of the second sieve plate 304 and the first sieve plate 302 overlap each other, so that the raw materials can pass through the sieve holes of the second sieve plate 304 and the first sieve plate 302 and be screened. When the screening is completed, the reset rod 201 is rotated to make the disc 204 start When the disc 204 is no longer in contact with the vertical plate 3054, the multiple second springs 3053 will synchronously squeeze the connecting plate 3052 to move the connecting plate 3053 toward the direction of the stirring rod 106, so that the vertical plate 3054 protrudes from the vertical groove of the mixing barrel 105, and the bottom end of the connecting plate 3052 pushes the second sieve plate 304 to move away from the second springs 3053 through the rectangular frame 3051, so that the sieve holes of the second sieve plate 304 and the first sieve plate 302 are staggered with each other, thereby realizing automatic resetting, which is convenient for mixing and screening new raw materials.

[0056] Furthermore, a linkage plate 306 is slidably penetrated on one side of the mixing barrel 105, the top of the second sieve plate 304 is fixedly connected to a limit frame 307, the bottom end of the linkage plate 306 is slidably set in the limit frame 307, the rod surface of the stirring rod 106 is fixedly connected to a rotating plate 308 whose position corresponds to the linkage plate 306, and two fine plates 309 are fixedly connected to the inner wall of the processing box 101, and a plurality of scrapers 310 are fixedly connected between the opposite surfaces of the two fine plates 309, and the top of each scraper 310 is provided with a right-angle chamfer.

[0057] One end of each first spring 303 away from the first sieve plate 302 is in contact with the processing box 101, so that the first sieve plate 302 is located directly below the mixing barrel 105. When the second sieve plate 304 slides on the first sieve plate 302, the linkage plate 306 will move synchronously along the inner wall of the limit frame 307, and the moving direction of the second sieve plate 304 is perpendicular to the fixed rod 301, so as not to drive the first sieve plate 302 to move. The ends of the linkage plate 306 and the rotating plate 308 are both provided with chamfers with smooth transitions. When the linkage plate 306 and the rotating plate 308 are close to each other, and the lateral end of the linkage plate 306 and the rotating plate 308 gradually form a straight line, the relative distance between the linkage plate 306 and the rotating plate 308 gradually becomes less than zero, and then the chamfered end of the rotating plate 308 contacts the chamfered end of the linkage plate 306 and squeezes the linkage plate 306 away from the stirring rod 106.

[0058] At this time, the bottom end of the linkage plate 306 pushes the second sieve plate 304, and the second sieve plate 304 will synchronously drive the first sieve plate 302 to slide along the two fixed rods 301. During the sliding of the first sieve plate 302, the first sieve plate 302 squeezes the plurality of first springs 303, and the squeezed first springs 303 push the first sieve plate 302 in the opposite direction. At this time, the first sieve plate 302 moves back and forth along the two fixed rods 301 under the reaction force, and the rotating plate 308 is driven by the stirring rod 106 to repeatedly push the linkage plate 306, so that the first sieve plate 302 and the second sieve plate 304 are constantly moving. At this time, the sieve holes of the first sieve plate 302 and the second sieve plate 304 are still staggered with each other, and the raw materials are still located in the mixing barrel 105. In addition, the rectangular frame 3051 will slide synchronously with the second sieve plate 304, and the rectangular frame 3051 will not conflict with the position of the connecting plate 3052.

[0059] When screening is performed, the connecting plate 3052 pulls the second sieve plate 304 through the rectangular frame 3051, so that the sieve holes of the first sieve plate 302 and the second sieve plate 304 are staggered, and the first sieve plate 302 and the second sieve plate 304 are in motion, so that the raw materials on the second sieve plate 304 will not stay on the second sieve plate 304, and through the movement, it is difficult for the powder raw materials to be blocked in the sieve holes, while increasing the screening speed to reduce the blockage phenomenon. The two fine plates 309 are both located at the bottom of the first sieve plate 302. During the movement of the first sieve plate 302, the raw materials attached to the bottom of the first sieve plate 302 can be scraped off by the scraper 310. The top of each scraper 310 is provided with a right-angle chamfer to make it difficult for the raw materials to adhere to the top of the scraper 310. When the stirring rod 106 stops rotating, the first spring 303 is no longer squeezed by the first sieve plate 302, so that the first sieve plate 302 automatically resets to the bottom of the mixing barrel 105.

[0060] Furthermore, a discharge box 107 that passes through the processing box 101 is fixedly connected to one side of the processing box 101, and one end of the discharge box 107 that faces the mixing barrel 105 is connected to the mixing barrel 105, and an adjusting rod 108 is threadedly connected to one side of the discharge box 107. An arc panel 109 is slidably provided on the top of the inner wall of the discharge box 107, and one end of the adjusting rod 108 passes through the discharge box 107 and is rotatably connected to one side of the arc panel 109. A straight plate 110 is fixedly connected to one side of the discharge box 107, and a plurality of inclined plates 111 distributed in a ring are fixedly connected to the bottom of the side wall of the stirring rod 106.

[0061] The arc surface of the arc plate 109 fits with the inner wall surface of the mixing barrel 105 so that the arc plate 109 will not block the rotation of the stirring rod 106. After the raw materials are screened, some agglomerated raw materials may not be crushed and discharged in time. The arc plate 109 is moved away from the mixing barrel 105 by rotating the adjusting rod 108, so that the discharge box 107 is connected to the mixing barrel 105. Then, the stirring rod 106 is driven to rotate by the servo motor 102, so that the residual raw materials are driven by the stirring blade into the discharge box 107, so that the residual raw materials are discharged in time.

[0062] The inclined plate 111 is close to the second sieve plate 304. The raw materials at the bottom of the mixing barrel 105 can be scooped up through the inclined plate 111 to accelerate the mixing of the raw materials. The raw materials stuck on the sieve holes of the second sieve plate 304 can also be broken through the inclined plate 111, so that the raw materials can be sieved or discharged through the discharge box 107. After the discharge is completed, the adjusting rod 108 is rotated again to make the arc panel 109 cover the opening of the discharge box 107. The adjusting rod 108 is limited by the straight plate 110 so that the arc surface of the arc panel 109 is aligned with the inner wall of the mixing barrel 105.

[0063] Furthermore, a threaded rod 112 is threadedly connected to one side of the processing box 101, and an inspection port is provided on one side and the top of the processing box 101. An L-shaped plate 113 is rotatably connected to the inner wall of the inspection port. A threaded hole that fits the threaded rod 112 is provided on one side of the L-shaped plate 113, and one end of the threaded rod 112 passes through the processing box 101 and is threadedly connected to the threaded hole of the L-shaped plate 113.

[0064] The L-shaped plate 113 is matched with the shape of the inspection port. The threaded rod 112 is rotated so that it is no longer inserted into the threaded hole of the L-shaped plate 113. Then, the L-shaped plate 113 can be deflected and the components inside the inspection port can be inspected. At the same time, the space inside the processing box 101 can also be cleaned to ensure the cleanliness of the preparation process. The inspection port can also facilitate the user to increase the number of tooth blocks 2052, so as to adjust the descending speed of the disc 204 according to the amount of raw materials used. After the inspection is completed, the L-shaped plate 113 is rotated and reset, and the threaded rod 112 is rotated to insert it into the threaded hole of the L-shaped plate 113.

[0065] During use, a corresponding number of tooth blocks 2052 are installed on the driving disk 2051 according to the amount of raw materials used, and the tooth blocks 2052 are fixed by the fixing plates 2053. Then, the first group of raw materials are transported to the mixing barrel 105 through the feeding pipe 103, and then the servo motor 102 is started to drive the stirring rod 106 to rotate forward, and the stirring rod 106 stirs and mixes the raw materials in the mixing barrel 105 through the stirring blades. An upward airflow can be generated by a plurality of stirring blades, so that the powdered raw materials are stirred by air in the mixing barrel 105. When the mixing is completed, the servo motor 102 is started to drive the stirring rod 106 to rotate in the reverse direction. At this time, the stirring blades rotate in the reverse direction and generate a downward airflow, and the tooth blocks 2052 will mesh with the tooth ring on the outer side of the flywheel 203 and drive the flywheel 203 to rotate, and the flywheel 203 drives the driving rod 202 to make the disc 204 descend along the inner wall of the mixing barrel 105;

[0066] When the disc 204 and the vertical plate 3054 come into contact with each other, the disc 204 will squeeze the vertical plate 3054 into the vertical groove. At the same time, the bottom end of the connecting plate 3052 pulls the second sieve plate 304 to move in the direction of the second spring 3053 through the rectangular frame 3051, so that the sieve holes of the second sieve plate 304 and the first sieve plate 302 overlap with each other, so that the raw materials can pass through the sieve holes of the second sieve plate 304 and the first sieve plate 302 and be sieved. In the process of the disc 204 continuously descending, the disc 204 will continuously reduce the mixing space of the mixing barrel 105, so that the raw materials can be screened. The space for the powder raw materials to move is reduced, and the downward wind field generated by the stirring blade allows the raw materials to be screened quickly. In addition, the chamfered end of the rotating plate 308 contacts the chamfered end of the linkage plate 306, and the second screen plate 304 drives the first screen plate 302 to slide along the two fixed rods 301, so that the first screen plate 302 and the second screen plate 304 are in a moving state. Through the movement, the powder raw materials are difficult to be blocked in the sieve holes, and the screening speed is increased. The scraper 310 can scrape off the raw materials attached to the bottom of the first screen plate 302;

[0067] After the screening is completed, the arc plate 109 is moved away from the mixing barrel 105 by rotating the adjusting rod 108, so that the residual raw materials are discharged in time by the discharge box 107. After the discharge is completed, the adjusting rod 108 is rotated again to make the arc plate 109 cover the opening of the discharge box 107, and then the servo motor 102 is turned off, and the reset rod 201 is rotated to make the disc 204 start to rise, and then the first sieve plate 302 is automatically reset by the first spring 303. When the disc 204 is no longer in contact with the vertical plate 3054, the plurality of second springs 3053 will synchronously squeeze the connecting plate 3052 to make the vertical plate 3054 automatically reset, and the sieve holes of the second sieve plate 304 and the first sieve plate 302 will automatically stagger with each other and automatically reset by the first spring 303. The screened raw materials are discharged through the discharge hopper 104, and then the second group of raw materials are mixed and screened in this cycle, and then the screened first group of raw materials and the second group of raw materials are mixed and screened again, and finally the tea polyphenol compound feed antioxidant is prepared.

[0068] A method for preparing a tea polyphenol compound feed antioxidant, the preparation method is applicable to any of the above preparation equipments, and the preparation method comprises the following steps:

[0069] Step 1: Weigh tea polyphenols with a concentration of 10% to 30% by mass percentage, the content of tea polyphenols is 10% to 30%, the content of PG is 1% to 10%, the content of synergist is 1% to 10%, the content of emulsifier is 1% to 10%, the content of dispersant is 1% to 10%, the content of carrier is 30% to 60%, and the sum of the total mass percentage of each group is 100%;

[0070] Step 2: The temperature is controlled below 50°C, and part of the carrier is mixed with the synergist, emulsifier, and dispersant, and then crushed and sieved;

[0071] Step 3: Evenly mix the remaining carrier and tea polyphenols, crush and sieve them, and then evenly mix them with the sieved mixture in step 2 to prepare a tea polyphenol compound feed antioxidant.

[0072] Embodiment 2

[0073] Reference Figure 5 As shown, the difference from the first embodiment is that a plurality of circular openings are opened on the top of the disc 204, and a one-way exhaust valve 206 is fixedly connected to the inner wall of each circular opening.

[0074] When the stirring rod 106 generates an upward airflow, the air cannot pass through the one-way exhaust valve 206. When the stirring rod 106 rotates in the opposite direction to generate a downward airflow, a negative pressure is generated at the top of the mixing barrel 105, thereby generating suction. The air on the top of the disc 204 can pass through the one-way exhaust valve 206 and enter the mixing barrel 105, so that the raw materials can be quickly screened.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
