Description

Technical Field

[0001] This invention relates to the field of food sterilization, and more particularly to a food additive sterilization device. Background Technology

[0002] Food additives are artificial or natural substances added to food to improve its quality, color, aroma, and flavor, as well as for preservation, freshness, and processing needs. They play an important role in the food industry, and their proper use can enhance food quality, safety, and the eating experience.

[0003] Vitamin C is a common water-soluble vitamin food additive, often used as an antioxidant and nutritional fortifier, and widely applied in the processing of beverages, baked goods, and meat products. In its production process, sterilization is often required after crystallization and drying to remove any remaining microorganisms. However, during the actual sterilization of vitamin C, to increase the contact area between the high-temperature air and the food additive, it is often allowed to fall in a curtain-like manner. However, this rapid descent reduces the contact time between the food additive and the high-temperature air, resulting in insufficient interaction time between the food additive and the sterilization medium. Consequently, it becomes difficult to completely kill all the target microorganisms in the food additive, severely impacting the sterilization effect. Summary of the Invention

[0007] Preferably, two auxiliary frames are symmetrically fixedly installed on the upper end of the main frame, and a material guiding ring is fixedly installed on the upper end of the two auxiliary frames.

[0008] Preferably, a disc shell is slidably mounted on the upper end of the bearing rod, and the upper end of the disc shell is fixed to the middle of the lower end of the conical disc.

[0009] Preferably, the pushing member includes a sliding sleeve slidably mounted on the lower part of the bearing rod, an extension frame extending from one side of the sliding sleeve, a pressure frame fixedly mounted on the upper end of the extension frame, the upper end of the pressure frame being fixed to the lower end of the cone disc, protruding claws extending from the sides of both top sleeves, two connecting plates symmetrically extending from the sides of the bearing rod, the connecting plates being close to the lower part of the top sleeves, and flip-top frames rotatably mounted at the ends of both connecting plates, one end of the flip-top frame abutting the lower end of the protruding claw, two bearing cavities symmetrically opened on the pressure frame, and pressure claws rotatably mounted inside both bearing cavities, the end of the lower pressure claw abutting the other end of the lower flip-top frame, and the end of the upper pressure claw being close to the upper end of the other flip-top frame.

[0010] Preferably, a limiting frame extends from the upper end of the connecting plate, the limiting frame rests on the upper end of the flip-top frame, two concave seats are symmetrically fixedly installed on the side of the pressure frame, a first connecting block is rotatably installed on the inner side of the concave seats, a guide shell extends from the end of the first connecting block, a guide post is slidably installed inside the guide shell, the guide post extends through the end of the guide shell, a second connecting block extends from the end of the guide post, the second connecting block is rotatably connected to the middle of the pressure claw, a top claw spring is wound around the outer side of the guide shell and the outer side of the guide post, one end of the top claw spring is fixed to the first connecting block, and the other end of the top claw spring is fixed to the second connecting block.

[0011] Preferably, a curved frame extends from the other side of the sliding sleeve, a drive rod is rotatably mounted at the lower front end of the sterilization box, the drive rod passes through the interior of the sterilization box, a lever extends from the end of the drive rod, a connecting frame is rotatably mounted at the end of the lever, and the end of the connecting frame is rotatably connected to the end of the curved frame.

[0012] Preferably, a servo motor is fixedly installed at the lower front end of the sterilization box, and the output end of the servo motor is fixed to the drive rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When food additives are discharged from the feed hopper and fall onto the conical disc, forming a curtain of material as they fall downwards, the curtain of material first falls onto the upper lifting ring, where it briefly pauses under the support of the upper lifting ring. Then, the upper lifting ring moves upwards to lift the food additives, causing them to continue falling downwards to form another curtain of material. At this point, the curtain of material falls onto the lower lifting ring, where it briefly pauses under the support of the lower lifting ring. Then, the lower lifting ring moves upwards to lift the food additives, causing them to fall downwards again to form another curtain of material before being discharged onto the discharge hopper. This process of allowing the food additives to pause briefly as they fall to form a curtain of material increases the contact time between the food additives and the high-temperature air, thus allowing sufficient contact time between the food additives and the sterilization medium to completely kill the target microorganisms in the food additives, thereby improving the sterilization effect.

[0015] 2. The rotating drive rod drives the lever to rotate, which in turn drives the connecting frame to move and push the sliding sleeve, allowing it to slide on the bearing rod. This causes the pressure frame to reciprocate up and down. When the pressure frame moves down, the cone disc moves down synchronously. At this time, the sealing ring slides on the feed hopper, and the lower pressure claw, driven by the pressure frame, presses the lower flip-top frame down, causing it to rotate and push the lower convex claw, thus moving the lifting ring on the lower top sleeve up. This causes the food additive on the lower lifting ring to fall down. At this time, the lower pressure claw, through the lower flip-top frame, allows the lower lifting ring to return to its original position under its own weight after being released from the pressure of the lower pressure claw. When the return to its original position is complete, the upper pressure claw, driven by the pressure frame, presses onto the upper flip-top frame. Then, the upper pressure claw presses against the upper flip-top frame to repeat the above operation, causing the food additive on the upper lifting ring to fall down and return to its original position. When the reset is complete, the sealing ring slides to the cone block, opening the gap between the feed hopper and the cone block. This allows the food additives in the feed hopper to be discharged from the gap onto the cone plate and fall down along it. Then, the pressure frame moves upward, causing the sealing ring to reset and re-seal the gap. Simultaneously, the pressure claw moves upward and resets. This cycle repeats, allowing the upper food additives to fall only after the lower ones have finished falling. This prevents the upper and lower food additives from falling simultaneously, which could prevent them from landing on the lifting ring and thus avoid a short-term pause. It also prevents the upper food additives from accumulating on top of the lower ones during simultaneous falling, preventing the lower ones from being fully discharged and causing them to be overheated, resulting in functional failure and flavor deterioration. This ensures the quality of the food additives during sterilization. Attached Figure Description

Detailed Implementation

[0027] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0028] like Figures 1-10The illustrated food additive sterilization device includes a sterilization chamber 1. A discharge hopper 2 is installed at an angle on the bottom surface of the sterilization chamber 1. Since using the high-temperature air generated by the sterilization chamber 1 to heat and sterilize food additives is existing technology and widely used, it is not described in detail here. The discharge hopper 2 extends through the side of the sterilization chamber 1, catching and discharging the falling food additives. A feed hopper 4 is fixedly installed at the upper end of the sterilization chamber 1, with its lower part extending through the interior of the sterilization chamber 1. The feed hopper 4 serves to feed the food additives. A sealing ring 9 is slidably installed on the feed hopper 4, which seals the gap between the feed hopper 4 and the cone block 13. A cone disc 10 extends coaxially from the lower end of the sealing ring 9. A cone block 13 is fixedly installed on the lower inner edge of the feed hopper 4, leaving a gap between the cone block 13 and the lower end face of the feed hopper 4. The cone block 13 guides the food additives out of the gap. The cone block 13 fits against the inner wall of the sealing ring 9, preventing the food additives from falling into the sealing ring 9. A bearing rod 5 is slidably installed coaxially at the lower end of the cone disc 10. The lower end of the bearing rod 5 is fixed to the discharge hopper 2, and the bearing rod 5 bears the load. The supporting rod 5 has two main retaining frames 32 vertically fixedly installed on its outer surface. Each main retaining frame 32 has an inner retaining ring 12 and an outer retaining ring 36 fixedly installed at its end. The main retaining frames 32 fix the inner retaining ring 12 and the outer retaining ring 36. The outer retaining ring 36 is located outside the inner retaining ring 12, with the upper end of the inner retaining ring 12 higher than the upper end of the outer retaining ring 36, allowing the food additive to fall from the outside. A lifting ring 34 is fitted between the inner retaining ring 12 and the outer retaining ring 36. The inner retaining ring 12 and the outer retaining ring 36 can block the food additive, allowing it to fall within the designated area. The lifting ring 34 has a top sleeve 21 connected to its lower end. The top sleeve 21 is slidably connected to the bearing rod 5. The top sleeve 21 serves to guide and support the lifting ring 34. The lower part of the bearing rod 5 is provided with a pusher, which is connected to the top sleeve 21 and the cone disc 10. The lifting ring 34 can receive the food additives that fall and form a curtain of material, allowing them to stay briefly. This increases the contact time between the food additives and the high-temperature air, thus allowing the food additives and the sterilization medium to have sufficient contact time, so that the target microorganisms in the food additives are completely killed, thereby improving the sterilization effect.

[0029] The upper end face of the lifting ring 34 is inclined outward. When the lifting ring 34 lifts the food additive higher than the outer retaining ring 36, the food additive will fall downward from the outside under the action of the upper inclined surface of the lifting ring 34. Three ring frames 35 are fixedly installed in a ring array at the lower end of the lifting ring 34. The ends of the ring frames 35 are fixed to the top sleeve 21. The ring frames 35 serve to fix the lifting ring 34 and the top sleeve 21 together.

[0030] Two auxiliary frames 33 are symmetrically fixedly installed on the upper end of the main frame 32. The upper ends of the two auxiliary frames 33 are fixedly installed with feeding rings 11. The auxiliary frames 33 serve to fix the feeding rings 11. The upper end of the feeding rings 11 is inclined inward, which can receive and guide the falling food additives so that they can fall accurately onto the lifting rings 34. The centers of the feeding rings 11, the inner baffle ring 12, the outer baffle ring 36, and the lifting rings 34 are coaxial with the center of the bearing rod 5.

[0031] A disc shell 14 is slidably mounted on the upper end of the support rod 5. The upper end of the disc shell 14 is fixed to the middle of the lower end of the cone disc 10. The disc shell 14 can cooperate with the support rod 5 to guide the cone disc 10.

[0032] The pushing component includes a sliding sleeve 16 slidably mounted on the lower part of the bearing rod 5. An extension frame 15 extends from one side of the sliding sleeve 16, serving as a connection. A pressure frame 8 is fixedly mounted on the upper end of the extension frame 15, driving the pressure claw 19 and the conical disc 10 to move. The upper end of the pressure frame 8 is fixed to the lower end of the conical disc 10. Both top sleeves 21 have protruding claws 22 extending from their sides. Two connecting plates 23 extend symmetrically from the side of the bearing rod 5, near the lower part of the top sleeves 21. A flip-top frame 20 is rotatably mounted on the ends of both connecting plates 23, connecting the flip-top frame 20. One end of the flip-top frame 20 abuts against the lower end of the protruding claw 22. Two bearing cavities 25 are symmetrically formed on the pressure frame 8, each containing a pressure claw 19. The lower pressure claw 19 abuts against the lower flip-top frame. At the other end of the frame 20, the upper pressure claw 19 is close to the upper end of the upper flip frame 20. The lower pressure claw 19, driven by the pressure frame 8, presses the lower flip frame 20 downward, causing it to rotate and move the lower protruding claw 22, thereby moving the lifting ring 34 on the lower top sleeve 21 upward, causing the food additive on the lower lifting ring 34 to fall. At this time, the lower pressure claw 19 passes through the lower flip frame 20, allowing the lower lifting ring 34 to return to its original position by its own weight after the pressure of the lower pressure claw 19 is removed. When the return is complete, the upper pressure claw 19, driven by the pressure frame 8, presses onto the upper flip frame 20. Then, the upper pressure claw 19 presses the upper flip frame 20 to repeat the above operation, causing the food additive on the upper lifting ring 34 to fall and return to its original position. After the lower food additive has fallen, the upper food additive begins to fall.

[0033] A limiting frame 24 extends from the upper end of the connecting plate 23. The limiting frame 24 rests on the upper end of the flip-top frame 20 and can limit the flip-top frame 20. Two concave seats 26 are symmetrically fixedly installed on the side of the pressure frame 8. A first connecting block 27 is rotatably installed on the inner side of the concave seat 26. The concave seat 26 serves to support the first connecting block 27. A guide shell 28 extends from the end of the first connecting block 27. A guide post 29 is slidably installed inside the guide shell 28. The guide shell 28 and the guide post 29 serve to prevent the top claw spring 30 from bending and to position the pressure claw 19 at its reset position. The guide post 29 extends through the end of the guide shell 28 and a second connecting block 31 extends from the end of the guide post 29. The second connecting block 31 is connected to the pressure claw 19. The middle part of the claw 19 is rotatably connected, and the outer side of the guide shell 28 and the outer side of the guide post 29 are wound with a top claw spring 30. One end of the top claw spring 30 is fixed to the first connecting block 27. The top claw spring 30 can lift the pressure claw 19 to reset. The other end of the top claw spring 30 is fixed to the second connecting block 31. When the pressure frame 8 moves upward and drives the pressure claw 19 to move upward and reset, when the upward pressure claw 19 passes the flipping frame 20, the flipping frame 20 cannot flip upward due to the effect of the limiting frame 24. Therefore, it will generate a pushing force on the pressure claw 19. At this time, the pressure claw 19 rotates and gradually rotates into the bearing cavity 25. At the same time, the guide post 29 slides in the guide shell 28 and the top claw spring 30 retracts, allowing the pressure claw 19 to rotate normally, so that the pressure claw 19 can pass smoothly through the flipping frame 20 and complete the reset.

[0034] A curved frame 17 extends from the other side of the sliding sleeve 16. A drive rod 6 is rotatably installed at the lower front end of the sterilization box 1. The drive rod 6 passes through the interior of the sterilization box 1. A lever 18 extends from the end of the drive rod 6. A connecting frame 7 is rotatably installed at the end of the lever 18. The end of the connecting frame 7 is rotatably connected to the end of the curved frame 17. The rotating drive rod 6 can drive the lever 18 to rotate, thereby driving the connecting frame 7 to move to push the sliding sleeve 16, so that the sliding sleeve 16 can slide on the bearing rod 5, thereby driving the pressure frame 8 to move up and down reciprocally.

[0035] A servo motor 3 is fixedly installed at the lower front end of the sterilization box 1. The output end of the servo motor 3 is fixed to the drive rod 6, and the servo motor 3 drives the drive rod 6 to rotate.

[0036] During sterilization, the servo motor 3 drives the lever 18 on the drive rod 6 to rotate, which in turn drives the connecting frame 7 to move and push the sliding sleeve 16, allowing the sliding sleeve 16 to slide on the bearing rod 5. This causes the pressure frame 8 to move up and down reciprocally. When the pressure frame 8 moves down, the cone disc 10 moves down synchronously. At this time, the sealing ring 9 slides on the feed hopper 4, while the lower pressure claw 19, driven by the pressure frame 8, presses the lower top frame 20 down, causing it to rotate and move the lower protruding claw 22, thereby driving the lifting material on the lower top sleeve 21. Ring 34 moves upward, causing the food additives on the lower lifting ring 34 to fall. At this time, the lower pressing claw 19, through the lower flipping frame 20, allows the lower lifting ring 34 to return to its original position under its own weight after the pressing claw 19 is removed. When the return is complete, the upper pressing claw 19, driven by the pressing frame 8, presses onto the upper flipping frame 20. Then, the upper pressing claw 19 presses against the upper flipping frame 20 to repeat the above operation, causing the food additives on the upper lifting ring 34 to fall and return to its original position. When the process is complete, the sealing ring 9 slides to the cone block 13, opening the gap between the feed hopper 4 and the cone block 13. This allows the food additive in the feed hopper 4 to be discharged from the gap onto the cone plate 10 and fall down along the cone plate 10. Then, the pressure frame 8 moves upward, causing the sealing ring 9 to reset and re-seal the gap. At the same time, the pressure claw 19 moves upward and resets. This cycle repeats so that, under the above operation, the food additive is discharged from the feed hopper 4 onto the cone plate 10 and falls down along the cone plate 10 to form a material curtain. The material curtain will fall from the top first. The food additive is briefly held on the upper lifting ring 34 under its support. Then, the upper lifting ring 34 moves upward to lift the food additive, causing it to fall downward to form a curtain of material. At this time, the curtain of material falls onto the lower lifting ring 34 and briefly holds on its support. Then, the lower lifting ring 34 moves upward to lift the food additive, causing it to fall downward again to form a curtain of material that falls onto the discharge hopper 2 for discharge. During this process, the sterilization chamber 1 generates high-temperature air to heat and sterilize the falling food additive.
