Description

Technical Field

[0001] This invention relates to the field of protein powder production technology, specifically to a sterilization device for protein powder production. Background Technology

[0002] The core production process of protein powder starts with the purification of raw materials, followed by separation / concentration to obtain high-purity protein, and then drying, shaping and subsequent processing to finally produce the product. This process can precisely control the purity of protein and the form of the product, which is the key to ensuring the quality of protein powder. Microwave heating sterilization is used in the production of protein powder to kill harmful microorganisms in the raw materials and ensure product safety. The core advantage of microwave heating in the production of protein powder is that it is fast and uniform. In existing technologies, to ensure that protein powder does not easily deteriorate within its shelf life, manufacturers generally use sterilization equipment to process it. During microwave sterilization, protein powder itself is mostly in the form of fine particles, and some types of protein powder have a certain degree of stickiness. Under the action of microwave heating, the forces between its particles change, making it easier to adhere to the surface of the conveyor belt in contact with it. On the other hand, during the microwave heating process, the ambient temperature around the conveyor belt and protein powder will rise rapidly, which may cause some components in the protein powder to slightly melt or soften, further increasing its adhesion to the conveyor belt. This makes it difficult for a large number of protein powder particles to enter the next stage with the normal operation of the conveyor belt, but instead they remain on the surface of the conveyor belt. This protein powder residue on the conveyor belt will re-enter the microwave heater with the circulation of the conveyor belt. When a new batch of protein powder to be sterilized enters the conveyor belt, the old protein powder residue on the conveyor belt will mix with the new protein powder, thus causing new protein powder contamination. More seriously, in the dead corners of the conveyor belt, such as the connection between the conveyor belt and the equipment, and the folds at the edge of the conveyor belt, the protein powder residue in these locations is often difficult to completely remove during conventional cleaning. Summary of the Invention

[0003] The purpose of this invention is to provide a sterilization device for protein powder production, in order to solve the problem mentioned in the background art that protein powder easily adheres to the surface of the conveyor belt when using microwave heating sterilization. When the protein powder remaining on the conveyor belt enters the microwave heater along with the conveyor belt, it easily causes new protein powder contamination when it re-enters the conveyor belt. In particular, if the protein powder is not thoroughly removed in the dead corners of the conveyor belt, these residues will repeatedly circulate with the conveyor belt, causing the growth of bacteria and mold.

[0004] The objective of this invention can be achieved through the following technical solutions: A sterilization device for protein powder production includes a fixed frame, a microwave heater, a metal protective cover, a conveyor belt, and two drive shafts. The metal protective cover is located at the upper middle of the fixed frame, and the microwave heater is located inside the middle of the metal protective cover. The two drive shafts are located at the top ends of the fixed frame, and the conveyor belt is sleeved on the outside of the two drive shafts. A powder blowing structure is provided between the two drive shafts and at the two side edges of the conveyor belt. The powder blowing structure includes a placement groove formed around the surface of the conveyor belt for conveying protein powder. A fixed plate is welded between the lower ends of the fixed frame, and a blower is installed on the surface of the fixed plate. The blowing end of the blower is connected to a connecting pipe. Fixed strips are installed on the top two sides of the fixed frame and on the two sides of the conveyor belt. An expansion air bladder is sleeved on the outside of each of the two fixed strips. The two ends of the connecting pipe are respectively connected to the two expansion air bladders. A row of first nozzles is formed on the opposite side of each of the two expansion air bladders. The first nozzles are located on the lower surface of the conveyor belt and are used to blow the protein powder adhering inside the placement groove.

[0005] As a preferred technical solution of the present invention, a row of reserved holes is opened on the side wall of both fixing strips, the two ends of the drive shaft are located inside the reserved holes, the end of the first nozzle is inclined upward, and the orientation of the first nozzle corresponds to the placement groove. The protein powder remaining inside the placement groove will rotate with the conveyor belt, and the placement groove can be cleaned by the first nozzle of the expansion air bag to avoid protein powder remaining inside the placement groove and prevent protein powder from being contaminated.

[0006] As a preferred embodiment of the present invention, a powder cleaning structure is provided between the opposing surfaces of the two fixed strips. The powder cleaning structure includes several sets of T-shaped grooves, with each set of T-shaped grooves arranged facing each other. Lifting blocks are slidably connected inside the two sets of T-shaped grooves. A fixed end is integrally provided at the bottom of each lifting block. A first fixed shaft is rotatably connected between the two fixed ends of the same set. A cleaning brush is provided outside the first fixed shaft. Each cleaning brush is in contact with the placement groove on the lower surface of the conveyor belt. The cleaning brush is used to further clean the dead corners of the protein powder in the placement groove.

[0007] As a preferred technical solution of the present invention, a reserved groove is provided at the top of the T-shaped groove, and a middle partition is embedded in the reserved groove. An adjusting bolt is provided in the middle of the middle partition, and the adjusting bolt is rotatably connected to the inside of the middle partition. The bottom end of the adjusting bolt is threadedly connected to the inside of the lifting block. The adjusting bolt and the lifting block are screwed together to ensure that the cleaning brush is always in contact with the inside of the placement groove.

[0008] As a preferred embodiment of the present invention, each adjusting bolt is provided with two limiting sleeves in the middle. The limiting sleeves are located on the upper and lower surfaces of the middle partition plate and are welded to the outside of the adjusting bolt.

[0009] As a preferred technical solution of the present invention, a baffle is integrally provided at the end of each of the first fixed shafts, and a plurality of second nozzles are provided on the opposite face of the two inflatable airbags at the ends of the first fixed shafts. The second nozzles are located on both sides of the ends of each of the first fixed shafts, and the airflow from the second nozzles is used to clean the cleaning baffles and cleaning brushes.

[0010] In a preferred embodiment of the present invention, the two fixed ends at both ends of the first fixed shaft are raised and lowered synchronously, and the second nozzle faces the cleaning brush. The cleaning brush outside the first fixed shaft cleans the lower surface of the conveyor belt and removes protein powder from the dead corners inside the placement groove. The second nozzle can also blow away the powder adhering to the cleaning brush to ensure that the protein powder is thoroughly removed from the placement groove of the conveyor belt. The adjusting bolt and the lifting block are threaded together. By screwing the lifting block into the adjusting bolt, the position of the fixed end and the first fixed shaft can be changed, thereby ensuring that the cleaning brush of the first fixed shaft is in contact with the conveyor belt and that the distance between the cleaning brush and the first fixed shaft is appropriate.

[0011] As a preferred technical solution of the present invention, a clamping structure is provided between the opposing surfaces of the two fixing strips. The clamping structure includes several sets of second fixing shafts. The two second fixing shafts in each set are located on both sides of the T-groove. The second fixing shafts are located at the inner ring of the conveyor belt. Movable sleeves are fitted on the outside of the second fixing shafts. The conveyor belt passes through the gap between the two movable sleeves and the first fixing shaft. The relative position of the first fixing shaft and the two movable sleeves is used to adjust the tension of the conveyor belt.

[0012] As a preferred embodiment of the present invention, auxiliary shafts are provided on both sides of the T-groove, the auxiliary shafts are installed inside the reserved holes, and the auxiliary shafts are in contact with the inner ring of the conveyor belt.

[0013] As a preferred technical solution of the present invention, the lifting block and the first fixed shaft move in the vertical direction, the two movable sleeves are used to guide the conveyor belt, and the second fixed shaft and the movable sleeves can guide both sides of the conveyor belt so that the conveyor belt can rotate normally; the clamping structure and the powder cleaning structure are combined, and the adjusting bolt is screwed into the lifting block to adjust the position of the first fixed shaft, which can increase the tension of the conveyor belt.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Equipped with a powder blowing structure, the protein powder remaining inside the placement tank will rotate with the conveyor belt and can be cleaned through the first nozzle of the inflatable air bladder, preventing protein powder residue from remaining inside the placement tank and thus preventing protein powder contamination. Equipped with a powder cleaning structure, the cleaning brush outside the first fixed shaft cleans the lower surface of the conveyor belt and cleans the protein powder in the dead corners inside the placement trough. The second nozzle can also blow away the powder adhering to the cleaning brush to ensure that the protein powder is completely removed from the placement trough of the conveyor belt. The adjusting bolt and the lifting block are threaded together. By screwing the lifting block into the adjusting bolt, the position of the fixed end and the first fixed shaft can be changed, thereby ensuring that the cleaning brush of the first fixed shaft is in contact with the conveyor belt and that the distance between the cleaning brush and the first fixed shaft is appropriate. Equipped with a clamping structure, the conveyor belt can be guided on both sides via a second fixed shaft and a movable sleeve, allowing the conveyor belt to rotate normally. The clamping structure is combined with a powder cleaning structure, and the position of the first fixed shaft can be adjusted by screwing the adjusting bolts into the lifting block, thereby increasing the tension of the conveyor belt.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:

[0019] Please see Figure 1 - Figure 3As shown, a sterilization device for protein powder production includes a fixed frame 1, a microwave heater 2, a metal protective cover 3, a conveyor belt 4, and two drive shafts 8. The metal protective cover 3 is located at the upper middle of the fixed frame 1, the microwave heater 2 is located inside the middle of the metal protective cover 3, and the two drive shafts 8 are located at the top ends of the fixed frame 1. The conveyor belt 4 is sleeved on the outside of the two drive shafts 8. The metal protective cover 3 is welded to the upper middle of the fixed frame 1, and the protein powder on the surface of the conveyor belt 4 can be sterilized by the microwave heater 2 in the middle of the metal protective cover 3. Sterilization is performed by adjusting the rotation speed of the conveyor belt 4 to control the time the protein powder remains inside the microwave heater 2. A powder blowing structure 5 is located between the two drive shafts 8 and at the two side edges of the conveyor belt 4. The powder blowing structure 5 includes a placement groove 58 formed around the surface of the conveyor belt 4. The placement groove 58 is used to transport the protein powder, which is then conveyed along with the conveyor belt 4. A fixing plate 53 is welded to the lower ends of the fixing frame 1. A blower 54 is mounted on the surface of the fixing plate 53. The blower 54 blows... A connecting pipe 55 is connected to the air end. A fixing plate 53 is installed at the lower end of the fixing frame 1, and a blower 54 is fixed to the surface of the fixing plate 53 by bolts. The blowing end of the blower 54 sends airflow into the connecting pipe 55. Fixing strips 51 are installed on both sides of the top of the fixing frame 1 and on both sides of the conveyor belt 4. An expansion air bag 56 is fitted on the outside of each of the two fixing strips 51. The two ends of the connecting pipe 55 are respectively connected to the two expansion air bags 56. A row of first nozzles 57 is opened on the opposite side of each of the two expansion air bags 56. The first nozzles 57 are located on the conveyor belt 4. At the lower surface of the conveyor belt 4, the first nozzle 57 is used to blow away the protein powder adhering inside the placement trough 58. The blower 54 blows air into the connecting pipe 55 and the expansion air bladder 56. When the expansion air bladder 56 is filled with gas, the gas is ejected from each of the first nozzles 57. Thus, each of the first nozzles 57 can blow away the placement trough 58 on the lower surface of the conveyor belt 4. The protein powder remaining inside the placement trough 58 can be cleaned by the airflow. The placement trough 58 then re-enters the metal protective cover 3 to prevent the residual protein powder from contaminating the new protein powder.

[0020] Please see Figure 3 As shown, a row of reserved holes 52 are opened on the side walls of the two fixing bars 51. The two ends of the drive shaft 8 are located inside the reserved holes 52. The end of the first nozzle 57 is inclined upward, and the orientation of the first nozzle 57 corresponds to the placement groove 58. The drive shaft 8 drives the conveyor belt 4 to rotate, thereby conveying the protein powder. The inclined arrangement of the first nozzle 57 can clean the protein powder inside the placement groove 58. The airflow can flow along the lower surface of the conveyor belt 4 to clean the protein powder in the placement groove 58.

[0021] It should be noted that some protein powder is put into the metal protective cover 3 from one end of the conveyor belt 4. The protein powder inside the metal protective cover 3 is sterilized by the microwave heater 2. The other end of the rotating conveyor belt 4 pours out the protein powder. Some protein powder remains inside the placement tank 58. At this time, the powder in the placement tank 58 can be cleaned by the powder blowing structure 5. Specifically, the blower 54 above the fixed plate 53 works and can vent air into the connecting pipe 55. The connecting pipe 55 and the expansion airbag 56 expand. The expansion airbag 56 is restricted by the fixed bar 51. The expansion airbag 56 blows the placement tank 58 of the conveyor belt 4 from a row of first nozzles 57. The powder in the dead corners inside the placement tank 58 is cleaned by the airflow. The protein powder remaining inside the placement tank 58 will rotate with the conveyor belt 4 and can be cleaned by the first nozzles 57 of the expansion airbag 56 to avoid protein powder remaining inside the placement tank 58.

[0022] Please see Figure 2 , Figure 4 - Figure 6 As shown, a powder cleaning structure 6 is provided between the opposing surfaces of two fixed strips 51. The powder cleaning structure 6 includes several sets of T-slots 66, with each set of T-slots 66 arranged facing each other. Lifting blocks 67 are slidably connected inside the two sets of T-slots 66. A fixed end 61 is integrally provided at the bottom end of each lifting block 67. The lifting block 67 can slide along the inside of the T-slot 66, so that the fixed end 61 and the lifting block 67 can rise and fall synchronously. A first fixed shaft 62 is rotatably connected between the two fixed ends 61 of the same set. A cleaning brush 63 is provided on the outside of the first fixed shaft 62. Each cleaning brush 63 is in contact with the placement groove 58 on the lower surface of the conveyor belt 4. The cleaning brush 63 is used to further clean the dead corner protein powder in the placement groove 58. The two ends of the first fixed shaft 62 are rotatably connected to the inside of the fixed end 61. The cleaning brush 63 on the outside of the first fixed shaft 62 can clean the lower surface of the conveyor belt 4, and the residual protein powder inside the placement groove 58 is cleaned by the cleaning brush 63.

[0023] Please see Figure 5 and Figure 6As shown, a reserved groove 610 is provided at the top of the T-shaped groove 66. A middle partition plate 68 is embedded in the reserved groove 610. The middle partition plate 68 can be inserted into the reserved groove 610 so that the threaded hole of the middle partition plate 68 is aligned with the lifting block 67. An adjusting bolt 69 is provided in the middle of the middle partition plate 68. The adjusting bolt 69 is rotatably connected to the inside of the middle partition plate 68. The bottom end of the adjusting bolt 69 is threadedly connected to the inside of the lifting block 67. The adjusting bolt 69 and the lifting block 67 are screwed together to ensure that the cleaning brush 63 is always in contact with the inside of the placement groove 58. The adjusting bolt 69 rotates relative to the middle partition plate 68, thereby adjusting the end of the adjusting bolt 69 and the lifting block 67 to change the position of the fixed end 61 and the first fixed shaft 62. The cleaning brush 63 outside the first fixed shaft 62 can clean the surface of the conveyor belt 4.

[0024] Please see Figure 6 As shown, each adjusting bolt 69 has two limiting sleeves in the middle. The limiting sleeves are located on the upper and lower surfaces of the intermediate partition 68 and are welded to the outside of the adjusting bolt 69. The adjusting bolt 69 passes through the interior of the intermediate partition 68, and the limiting sleeves are welded to the outside of the adjusting bolt 69 and on the upper and lower surfaces of the intermediate partition 68. Rotating the adjusting bolt 69 can raise and lower the lifting block 67 along the interior of the T-slot 66, thereby changing the position of each fixed end 61 and the lifting block 67.

[0025] Please see Figure 4 As shown, each of the first fixed shafts 62 has a baffle 64 integrally formed at its end. The baffle 64 and the fixed end 61 are integrally manufactured so that the fixed end 61 and the baffle 64 rotate synchronously. Each of the two inflatable airbags 56 is provided with a number of second nozzles 65 at the ends of the first fixed shafts 62. The second nozzles 65 are located on both sides of the ends of each first fixed shaft 62. The airflow from the second nozzles 65 is used to clean the cleaning baffle 64 and the cleaning brush 63. The two fixed ends 61 at both ends of the first fixed shaft 62 rise and fall synchronously. The second nozzles 65 face the cleaning brush 63. Under the action of the airflow, the second nozzles 65 will push the baffle 64 to blow, causing the first fixed shaft 62 to rotate. Alternatively, the baffle 64 can contact the conveyor belt 4 to rotate the first fixed shaft 62. The cleaning brush 63 on the outside of the first fixed shaft 62 can clean the protein powder inside the placement tank 58.

[0026] It should be noted that the first fixed shaft 62 is arranged laterally between the two fixed ends 61. The cleaning brush 63 on the outside of the first fixed shaft 62 can contact the conveyor belt 4. The second nozzle 65 faces the cleaning brush 63. Under the action of airflow, the second nozzle 65 will push the baffle 64 to blow, causing the first fixed shaft 62 to rotate. Alternatively, the baffle 64 can contact the conveyor belt 4 to rotate the first fixed shaft 62. The cleaning brush 63 on the outside of the first fixed shaft 62 can clean the protein powder inside the placement trough 58. When there is a gap between the cleaning brush 63 of the first fixed shaft 62 and the conveyor belt 4, the distance between the first fixed shaft 62 and the conveyor belt 4 can be adjusted. Specifically, the adjusting bolt 69 is adjusted so that the adjusting bolt 69 is rotatably connected relative to the middle partition 68. The end of the adjusting bolt 69 is threadedly connected to the lifting block 67, thereby lifting the block 67. Sliding along the inside of the T-slot 66, the fixed end 61 and the lifting block 67 are adjusted to rise. The first fixed shaft 62 between the two first fixed shafts 62 rises, allowing the cleaning brush 63 to contact the conveyor belt 4. Thus, the cleaning brush 63 can clean the protein powder inside the placement trough 58. The cleaning brush 63 outside the first fixed shaft 62 cleans the lower surface of the conveyor belt 4, cleaning the protein powder in the dead corners inside the placement trough 58. The second nozzle 65 can also blow away the powder adhering to the cleaning brush 63, ensuring that the protein powder is thoroughly removed from the placement trough 58 of the conveyor belt 4. The adjusting bolt 69 and the lifting block 67 are threaded together. By screwing the lifting block 67 into the adjusting bolt 69, the position of the fixed end 61 and the first fixed shaft 62 can be changed, thereby ensuring that the cleaning brush 63 of the first fixed shaft 62 is in contact with the conveyor belt 4 and that the cleaning brush 63 is in the correct position.

[0027] Please see Figure 2 , Figure 7 and Figure 8 As shown, a clamping structure 7 is provided between the opposing surfaces of the two fixing bars 51. The clamping structure 7 includes several sets of second fixing shafts 71. The two second fixing shafts 71 in each set are located on both sides of the T-slot 66. The second fixing shafts 71 are located at the inner ring of the conveyor belt 4. The second fixing shafts 71 are connected to the inner wall of the fixing bars 51 by threads. The outer side of each second fixing shaft 71 is fitted with a movable sleeve 72. The conveyor belt 4 passes through the gap between the two movable sleeves 72 and the first fixing shaft 62. The relative position of the first fixing shaft 62 and the two movable sleeves 72 is used to adjust the tension of the conveyor belt 4. By fitting the movable sleeves 72 on the outer side of the second fixing shaft 71 and the conveyor belt 4 passing through the gap between the first fixing shaft 62 and the two movable sleeves 72, the tension of the conveyor belt 4 can be pre-tightened.

[0028] Please see Figure 7 and Figure 8As shown, auxiliary shafts 73 are provided on both sides of the T-slot 66. The auxiliary shafts 73 are installed inside the reserved holes 52. The auxiliary shafts 73 are in contact with the inner ring of the conveyor belt 4. The movable sleeve 72 is in contact with the inner wall of the conveyor belt 4. The first fixed shaft 62 is in contact with the outer wall of the conveyor belt 4. Thus, the conveyor belt 4 can be limited by the first fixed shaft 62 and the movable sleeve 72. The lifting block 67 and the first fixed shaft 62 move in the vertical direction. The two movable sleeves 72 are used to guide the conveyor belt 4. When the conveyor belt 4 is relatively loose, the lifting block 67 can slide along the inside of the T-slot 66 by rotating the adjusting bolt 69. Thus, the conveyor belt 4 can be prevented from slipping after being tensioned.

[0029] It should be noted that, since the T-slot 66 is provided with second fixed shafts 71 on both sides, the conveyor belt 4 is located between the first fixed shaft 62 and the two second fixed shafts 71. Thus, the movable sleeve 72 can guide the conveyor belt 4. When the conveyor belt 4 is relatively loose during operation, it can be adjusted by the clamping structure 7. Specifically, rotating the adjusting bolt 69 causes the end of the adjusting bolt 69 to drive the lifting block 67. The lifting block 67 will slide along the inside of the T-slot 66. The first fixed shaft 62 and the fixed end 61 rise and fall synchronously with the lifting block 67. The change in position of the first fixed shaft 62 and the two second fixed shafts 71 changes the tension of the conveyor belt 4. The second fixed shafts 71 and the movable sleeve 72 can guide the two sides of the conveyor belt 4, so that the conveyor belt 4 can rotate normally. The clamping structure 7 and the powder cleaning structure 6 are combined, and the adjusting bolt 69 is screwed into the lifting block 67 to adjust the position of the first fixed shaft 62, which can increase the tension of the conveyor belt 4.

[0030] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
