Ultrasonic homogenizer for preparing active peptide nanoemulsion in oil tea seed

Abstract

This invention relates to the field of camellia seed processing, specifically to an ultrasonic homogenizer for preparing bioactive peptide nanoemulsions from camellia seeds. The homogenizer includes a homogenizing container and an ultrasonic generator, with the ultrasonic generator mounted on a second mounting plate. A base plate is located below the homogenizing container. This ultrasonic homogenizer for preparing bioactive peptide nanoemulsions from camellia seeds, through transmission, causes two push plates to accelerate the flow of material inside the homogenizing container. Simultaneously, condensate transported within the operating chamber further cools the material during the flow process. This facilitates cooling of material at different locations within the homogenizing container during the homogenization process, ensuring effective cooling at all points and preventing high-temperature denaturation of the internal bioactive peptides under high-temperature homogenization. This improves the effectiveness of the ultrasonic homogenizer in preparing bioactive peptides from camellia seeds.

Description

Technical Field

[0001] This invention relates to the field of camellia seed processing, specifically to an ultrasonic homogenizer for preparing active peptide nanoemulsions from camellia seeds. Background Technology

[0002] Camellia seeds are the fruit of the camellia tree, a major woody oilseed tree in my country, known as the "Oriental Tree." Camellia seeds are mainly composed of water, crude fat, starch, crude protein, tea seed polysaccharides, polyphenols, flavonoids, saponins, crude fiber, and a small amount of tannins. Among them, tea polyphenols, camellia glycosides, and squalene are its characteristic bioactive substances, which have the effects of lowering cholesterol, anti-aging, and preventing tumors.

[0003] Nanopeptides are proteins and also belong to health products. They can enhance capillary strength, continuously clear blood clots, lower cholesterol and triglycerides, promote metabolic decomposition, and remove LDL, thus safeguarding cardiovascular health. When used properly, they can be directly absorbed by the body, reaching the site of cell damage to rapidly repair cell defects and restore cellular physiological functions. Active peptides are a general term for oligopeptides and polypeptides that can regulate the life activities of organisms or possess certain physiological activities. Natural cells can synthesize polypeptide substances, and their organ and cellular functions are also regulated by polypeptides. Their main mechanism of action is to regulate related enzymes in the body, ensuring the smooth flow of metabolic pathways, or to influence protein synthesis by controlling transcription and translation, ultimately achieving specific physiological effects or exerting their pharmacological effects. Activated peptides are present in almost all life activities, mainly used to regulate metabolism, hormone secretion, neural activity, cell growth, and reproduction.

[0004] The process of preparing active peptide nanoemulsion from camellia seeds using an ultrasonic homogenizer utilizes the principle that sound waves and ultrasound rapidly and alternately compress and expand when they encounter an object. Under the action of ultrasound, when the material is in the expansion half-cycle, the liquid is stretched and expands as bubbles; when it is in the compression half-cycle, the bubbles contract. When the pressure change is large and the pressure is lower than the low pressure, the compressed bubbles will collapse rapidly, resulting in "cavitation" in the liquid. This phenomenon disappears with pressure changes and external pressure imbalances. At the moment the "cavitation" disappears, the surrounding liquid experiences a very large increase in pressure and temperature, resulting in a very complex and powerful mechanical stirring effect to achieve homogenization. However, during the ultrasonic homogenization process, since the active peptide nanoemulsion is a biochemical substance between amino acids and proteins, in order to avoid high-temperature denaturation of the internal active peptide nanoemulsion under high-temperature homogenization, the exterior of the ultrasonic homogenizer needs to be cooled. However, the existing ultrasonic homogenizer cooling methods can only cool the exterior of the ultrasonic homogenizer. During the homogenization process, the active peptide nanoemulsion inside the ultrasonic homogenizer is difficult to be effectively cooled and partially denatured, reducing the effectiveness of the ultrasonic homogenizer in preparing active peptide nanoemulsion from camellia seeds.

[0032] like Figure 1-8 The present invention discloses an ultrasonic homogenizer for preparing active peptide nanoemulsion from camellia seeds, comprising a homogenizing container 1 and an ultrasonic generator 2. The ultrasonic generator 2 is mounted on a second mounting plate 3. A base plate 5 is provided below the homogenizing container 1. A first lifting assembly for raising and lowering the second mounting plate 3 is provided on the base plate 5. Two nozzles 7 for cleaning after ultrasonic homogenization by the ultrasonic generator 2 are mounted on the second mounting plate 3. A conveying assembly for guiding and conveying cleaning fluid during the cleaning process is provided on the base plate 5. A support rod 6 is fixed on the homogenizing container 1. One end of the support rod 6 is rotatably connected to the base plate 5. A rotating assembly for rotating the homogenizing container 1 is provided on the base plate 5. Two symmetrically arranged sliding grooves 11 are provided on the homogenizing container 1. An operating box 12 is slidably connected to the two sliding grooves 11. A second lifting assembly for raising and lowering the two operating boxes 12 is provided on the base plate 5. A first cooling assembly and a second cooling assembly for cooling during the homogenization process are provided inside the two operating boxes 12.

[0033] The first cooling component includes two square slots 1501 formed on the operation box 12. Push plates 1502 are slidably connected to the two square slots 1501. Rectangular plates 1503 are fixed to opposite ends of the two push plates 1502. The operation box 12 is equipped with a pushing component for pushing the two rectangular plates 1503 and a guiding component for guiding the pushing process. The pushing component includes a first mounting plate 1601 fixed inside the operation box 12. A first disk 1602 is rotatably connected to the lower end of the first mounting plate 1601. A first motor 1603 for driving the first disk 1602 is mounted on the upper end of the first mounting plate 1601. A plurality of first protrusions 1604 for pushing the rectangular plates 1503 are arranged in a circular array on the first disk 1602. The guiding component includes a plurality of slide rods 1702 and sleeves 1701 respectively fixed on the two rectangular plates 1503. Each slide rod 1702 is slidably connected to the sleeve 1701. The first disc 1602 is internally equipped with a return spring for resetting the slide bar 1702. The first disc 1602 is driven to rotate by the first motor 1603. During the rotation of the first disc 1602, the two rectangular plates 1503 are pushed and squeezed by the first protrusions 1604, guided by the slide bar 1702 and sleeve 1701, and reset by the return spring. This causes the two rectangular plates 1503 to reciprocate by moving closer to each other or further away from each other as the first disc 1602 rotates. During the movement of the two rectangular plates 1503, the push plates 1502 on the two rectangular plates 1503 squeeze and push the material being homogenized in the two homogenizing chambers of the homogenizer 1, causing the material to flow during the homogenization process in the homogenizer 1. The flow of the material inside the homogenizing chamber facilitates the dissipation of heat generated on the material during the homogenization process.

[0034] Specifically, the second cooling component includes a fixed box 1801 located inside the operating box 12. The fixed box 1801 contains condensate. Two rectangular plates 1503 each contain an operating chamber. A delivery pipe 1802 and a return pipe 1803 connect the interior of the fixed box 1801 to the operating chambers of the rectangular plates 1503. The delivery pipe 1802 is equipped with a liquid extraction component. This component draws the coolant from inside the fixed box 1801 between the two one-way valves 1901 on the delivery pipe 1802 and then compresses it to the operating chamber of the push plate 1502. After cooling and use, the coolant delivered to the operating chamber is returned through the return pipe. 1803 flows back to the interior of the fixed box 1801, allowing the coolant to circulate between the fixed box 1801 and the pusher plate 1502. During the circulation process, the two pusher plates 1502 push and accelerate the flow of the material inside the homogenizer 1, while the condensate transported inside the operating chamber further cools and lowers the temperature of the material during the flow process. This facilitates the cooling treatment of the material at different locations during the homogenization process inside the homogenizer 1, ensuring the cooling effect of the material at each location inside the homogenizer 1. This prevents the internal nano-active peptides from undergoing high-temperature denaturation under high-temperature homogenization, thus improving the effect of the ultrasonic homogenizer in preparing nano-active peptides from camellia seeds.

[0035] Specifically, the liquid extraction assembly includes two one-way valves 1901 installed on the delivery pipe 1802. The conduction direction of the two one-way valves 1901 is from the inside of the fixed box 1801 to the inside of the operating chamber. A connecting pipe 1902 is connected to the delivery pipe 1802 and is located between the two one-way valves 1901. A piston rod 1903 is slidably connected to the connecting pipe 1902. A T-shaped plate 1904 is fixed to one end of the piston rod 1903. A squeezing assembly for intermittent squeezing of the T-shaped plate 1904 is provided on the first disc 1602. The delivery pipe 180... 2 is equipped with a reset assembly for resetting the T-shaped plate 1904 after compression. Through the compression assembly and the reset assembly, the T-shaped plate 1904 and the piston rod 1903 reciprocate on the connecting pipe 1902 as the transmission rod 2101 rotates. Since the conduction direction of the two one-way valves 1901 is from the inside of the fixed box 1801 to the inside of the operating chamber, through the reciprocating motion of the piston rod 1903, the coolant inside the fixed box 1801 is drawn into the two one-way valves 1901 of the conveying pipe 1802 and conveyed to the operating chamber of the push plate 1502 through compression.

[0036] Specifically, the extrusion assembly includes a transmission rod 2101 fixed to the lower end of the first disc 1602, one end of which is fixed to the second disc 2102. Multiple second protrusions 2103 for extruding the T-shaped plate 1904 are arrayed on the side wall of the second disc 2102. The resetting assembly includes multiple T-shaped rods 2001 slidably connected to the T-shaped plate 1904. One end of each T-shaped rod 2001 is fixed to the conveying pipe 1802. A first spring 2002 is sleeved on the side wall of each T-shaped rod 2001. During the rotation of the second disc 2102, the extrusion action of the second protrusions 2103 on the second disc 2102 on the T-shaped plate 1904 and the guiding action of the first springs 2002 on each T-shaped rod 2001 on the stressed T-shaped plate 1904 cause the T-shaped plate 1904 and piston rod 1903 to reciprocate on the connecting pipe 1902 as the transmission rod 2101 rotates.

[0037] Specifically, the second lifting assembly includes an L-shaped plate 1401 fixed to the upper end of the base plate 5, a lead screw 1403 rotatably connected to the L-shaped plate 1401, a second motor 1402 for driving the lead screw 1403 mounted on the upper end of the L-shaped plate 1401, a strip plate 1404 threadedly connected to the lead screw 1403, a first guide rod 1405 slidably connected to the strip plate 1404, the first guide rod 1405 being fixed between the L-shaped plate 1401 and the base plate 5, an annular plate 1406 sleeved on the side wall of the support rod 6, the annular plate 1406 rotatably connected to the upper end of the strip plate 1404, and two operating boxes. 12 is fixed to the upper end of the annular plate 1406. After the two operating boxes 12 are driven to rise, they abut against the support rod 6 and the inner wall of the homogenizer 1 on both sides respectively. The homogenizer 1 is divided into two homogenizing chambers by the two operating boxes 12. Two discharge pipes 13 are installed on the homogenizer 1. The two discharge pipes 13 are respectively connected to the two homogenizing chambers. The second motor 1402 drives the lead screw 1403 to rotate. During the rotation of the lead screw 1403, the strip plate 1404 is subjected to force and moves up and down through the mutual meshing transmission between the lead screw 1403 and the strip plate 1404 and the guiding action of the first guide rod 1405.

[0038] Specifically, the rotating assembly includes an L-shaped frame 1001 fixed to the upper end of the base plate 5, one end of the support rod 6 is rotatably connected to the L-shaped frame 1001, and a third motor 1002 for driving the support rod 6 is installed on the L-shaped frame 1001. The third motor 1002 facilitates the rotation of the support rod 6 and the homogenizer 1, and facilitates the switching of different homogenizers to move below the ultrasonic generator 2.

[0039] Specifically, the first lifting assembly includes a U-shaped frame 401 fixed to the upper end of the base plate 5. A threaded rod 402 is rotatably connected to the U-shaped frame 401. The second mounting plate 3 is meshed with the threaded rod 402. A second guide rod 404 is slidably connected to the second mounting plate 3. A fourth motor 403 for driving the threaded rod 402 is installed on the U-shaped frame 401. The threaded rod 402 is driven to rotate by the fourth motor 403. During the rotation of the threaded rod 402, the second mounting plate 3 is lifted and lowered by force through the meshing transmission between the threaded rod 402 and the second mounting plate 3 and the guiding effect of the second guide rod 404.

[0040] Specifically, the conveying assembly includes a fixed plate 801 fixed to the upper end of the base plate 5. A connecting plate 802 is connected to the fixed plate 801 via a connecting assembly. An inclined drainage plate 803 is fixed to the upper end of the connecting plate 802. When the connecting plate 802 is pushed, the drainage plate 803 is positioned below the ultrasonic generator 2. At this time, the cleaning fluid falling during the cleaning process is guided outward through the inclined drainage plate 803, preventing the cleaning fluid from falling into the homogenizer 1 and causing contamination.

[0041] Specifically, the connecting assembly includes connecting rods 901 that are slidably connected to the fixed plate 801. One end of each connecting rod 901 is fixed to the connecting plate 802. A second spring 902 is sleeved on the side wall of each connecting rod 901. The connecting rods 901 guide the movement of the connecting plate 802 after being subjected to force, and the second springs 902 facilitate the reset movement of the connecting plate 802.

[0042] Working Principle: When the ultrasonic homogenizer prepares and processes active peptide nanoemulsion from camellia seeds, the material to be homogenized is placed in the homogenizer container 1. After placement, the second mounting plate 3 moves towards the homogenizer container 1 via the first lifting component. During the movement of the second mounting plate 3, the ultrasonic generator 2 is pushed into the homogenizer container 1. The ultrasonic generator 2 homogenizes the material placed inside the homogenizer container 1. During the homogenization process, the strip plate 1404 is forced to move towards the homogenizer container 1 via the second lifting component. During the movement of the strip plate 1404, the two operating components are connected by the annular plate 1406. Box 12 is pushed into the interior of homogenizer 1 from sliding groove 11. The two symmetrical operating boxes 12 abut against the support rod 6 and the inner wall of homogenizer 1 respectively, dividing the interior of homogenizer 1 into two homogenization cavities. Through the rotation of the support rod 6 and homogenizer 1 by the two homogenization cavities on homogenizer 1 and the rotating component, the homogenization cavities on homogenizer 1 can be rotated to the ultrasonic generator 2 for homogenization. During the homogenization process, the two homogenization cavities can be homogenized on one side and loaded or unloaded on the other side, which facilitates the efficient preparation of active peptide nanoemulsion from camellia seeds by ultrasonic homogenizer.

[0043] During the homogenization process of dividing the homogenizing container 1 into two operating boxes 12, the first motor 1603 drives the first disc 1602 to rotate. During the rotation of the first disc 1602, the pushing and squeezing action of each first protrusion 1604 against the two rectangular plates 1503, the guiding action of each sliding rod 1702 and sleeve 1701 on the two rectangular plates 1503 after being subjected to force, and the reset action of the return spring on the rectangular plates 1503 after being subjected to force, cause the two rectangular plates 1503 to reciprocate, moving closer or further apart as the first disc 1602 rotates. During the movement of the two rectangular plates 1503... During the process, the push plates 1502 on the two rectangular plates 1503 squeeze and push the material being homogenized inside the two homogenizing chambers of the homogenizer 1, causing the material to flow during the homogenization process in the homogenizer 1. This flow facilitates the dissipation of heat generated within the homogenizing chambers. Furthermore, as the first disc 1602 rotates, the transmission rod 2101 drives the second disc 2102 to rotate. During the rotation of the second disc 2102, the second protrusions 2103 on the second disc 2102 sequentially squeeze the T-shaped plate 1904 and the T-shaped rods 2001. The first spring 2002 guides the T-shaped plate 1904 under force, causing the T-shaped plate 1904 and piston rod 1903 to reciprocate on the connecting pipe 1902 along with the rotation of the transmission rod 2101. Since the conduction direction of the two one-way valves 1901 is from the inside of the fixed box 1801 to the inside of the operating chamber, the reciprocating motion of the piston rod 1903 draws the coolant inside the fixed box 1801 into the space between the two one-way valves 1901 in the delivery pipe 1802 and delivers it to the operating chamber of the push plate 1502 through compression. After cooling and use, the coolant delivered to the operating chamber flows back to the fixed box 1801 through the return pipe 1803. Inside 801, coolant circulates between the fixed box 1801 and the pusher plate 1502. During the circulation, the two pusher plates 1502 push and accelerate the flow of material inside the homogenizer 1, while the condensate transported inside the operating chamber further cools and lowers the temperature of the material during the flow. This facilitates the cooling treatment of material at different locations during the homogenization process inside the homogenizer 1, ensuring the cooling effect of material at various locations inside the homogenizer 1. It also prevents the internal nano-active peptides from undergoing high-temperature denaturation under high-temperature homogenization, thus improving the effect of the ultrasonic homogenizer in preparing nano-active peptides from camellia seeds.

[0044] After homogenization of the active peptide nanoemulsion in camellia seeds, the homogenized material is discharged through the discharge pipe 13. Then, the ultrasonic generator 2 on the second mounting plate 3 is driven to reset through the first lifting component. After the reset, the material adhering to the surface of the ultrasonic generator 2 during the homogenization process is cleaned by water sprayed from the nozzle 7. During the cleaning process, the connecting plate 802 is pushed so that the diversion plate 803 is located below the ultrasonic generator 2. At this time, the cleaning liquid falling during the cleaning process is diverted to the outside through the inclined diversion plate 803, so as to prevent the cleaning liquid from falling into the homogenizing container 1 and causing contamination.
