Description

Technical Field

[0001] This utility model relates to the field of feed additive production technology, specifically to a high-efficiency drying equipment for feed additive production. Background Technology

[0002] Feed additives are essential raw materials used in the modern feed industry. They have significant effects on enhancing the nutritional value of basic feed, improving animal production performance, ensuring animal health, and improving the quality of livestock products. In the production process of feed additives, the drying of raw materials is a key process, especially for some heat-sensitive components and additive raw materials with small particle size (such as enzyme preparations, drug additives, vitamins, etc.).

[0003] The prior art (Chinese patent application number 202420641496.X, application date 2024-03-31) provides a circulating flow guiding mechanism for a drying device. By using an electric heating tube to heat the air, the hot air flows through a heating box, an air pump, a return pipe, a distribution pipe, a distribution ring, nozzles, an extraction pipe, a suction pipe, and a suction hood. At the same time, the hot air in the distribution ring is blown directly from multiple nozzles onto the feed additives in the container, ensuring the uniformity of drying of the feed additives and good practicality. Although the above device can effectively remove moisture from the raw materials, it often damages heat-sensitive substances during the process, affecting the activity and effect of the additives. In addition, traditional drying equipment also has certain shortcomings in terms of energy efficiency, uniformity, and environmental pollution control.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on existing equipment. Therefore, we have proposed a high-efficiency drying equipment for feed additive production that can effectively solve these problems. Utility Model Content

[0007] Preferably, both sides of the outer drying tube and the inner drying tube are connected to the end ring tube to balance the heat conduction and precisely control the temperature of each tube.

[0008] Preferably, a humidity monitor is fixedly installed on the inner right side of the drying tank, and the humidity monitor is electrically connected to the cylinder. The humidity monitor can monitor the humidity inside the drying tank in real time, thereby sensing the degree of drying of the feed additive.

[0009] Preferably, a stabilizing plate is fixedly connected to the right outer wall of the drying tank, and stabilizing vertical rods are fixedly connected between the bottom two ends of the stabilizing plate and the discharge channel. The top two ends of the sealing plate are formed with protruding plates, and the protruding plates are slidably connected to the outside of the two stabilizing vertical rods.

[0010] Preferably, the inside and right side of the drying tank are provided with an anti-residue component. The anti-residue component includes a mounting ring frame disposed on the left side inside the drying tank. A scraper is fixedly bonded to the outer side of the mounting ring frame, and the outer wall of the scraper is in contact with the inner wall of the drying tank. A threaded rod is threadedly connected to one end of the inner side of the mounting ring frame, and the right side of the threaded rod extends through to the outside of the drying tank and is fixedly connected to a gear. A rack is fixedly connected to one end of the sealing plate, and the rack meshes with the gear.

[0011] Preferably, the outer wall of the threaded rod is formed with a limiting protrusion, and the limiting protrusion is attached to the right side wall of the drying tank with the gear. The rack has an L-shaped plate structure and is attached to the right side of the gear.

[0012] Preferably, a stabilizing crossbar is fixedly connected to the inner wall of the drying tank, and one end of the mounting ring is slidably connected to the outer side of the stabilizing crossbar.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This high-efficiency drying equipment for feed additive production, by setting up external and internal drying pipes and controlling them within a low temperature range, can achieve low-temperature drying of feed additives, ensuring that the active ingredients of heat-sensitive additive raw materials are not damaged, thus guaranteeing their functionality and effectiveness. Furthermore, because the drying pipes are evenly laid on the drying tank, drive shaft, and threaded blades, the heat source generated can be concentrated and contacted with the tumbling feed additives from all directions, thereby improving heat transfer efficiency, shortening drying time, reducing energy consumption, and lowering production costs. The specific details are as follows:

[0014] (1) By combining the outer drying pipe and the inner drying pipe, and controlling the terminal system to precisely control them within a low temperature range, low-temperature drying of feed additives can be achieved, ensuring that the active ingredients of heat-sensitive additive raw materials are not destroyed, guaranteeing the functionality and effectiveness of the additives. Furthermore, since the outer drying pipe and the inner drying pipe are evenly laid on the drying tank, drive shaft, and threaded blades, the heat source generated can be concentrated and come into full contact with the tumbling feed additives, which accelerates heat exchange, improves heat conduction efficiency, shortens drying time, reduces energy consumption, and lowers production costs.

[0015] (2) By connecting both sides of the outer drying tube and the inner drying tube to the end ring tube, heat can be evenly conducted and the temperature of each tube can be precisely controlled, thereby achieving a precise and uniform low-temperature drying effect.

[0016] (3) By cooperating with the cylinder, the sealing plate and the humidity monitor, when the humidity drops to the required range, the humidity monitor sends an electrical signal to the control terminal system to control the cylinder to start operating. The cylinder drives the sealing plate to rise so that the discharge port is exposed, thereby realizing the discharge of feed additives.

[0017] (4) By setting up anti-residue components, when the cylinder drives the sealing plate to rise for material discharge, the rack rises synchronously and drives the gear to rotate, the threaded rod rotates synchronously, and drives the mounting ring and scraper to move to the right. In this way, the scraper can scrape the feed additives adhering to the inner wall of the drying tank and discharge the material through the drive shaft and threaded blades, thereby effectively reducing the residue of feed additives, helping to improve the cleanliness of the equipment and reduce the risk of cross-contamination.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figures 1-6This utility model provides the following technical solution: a high-efficiency drying equipment for feed additive production, including a drying tank 1. The bottom of the drying tank 1 is fixed by a support frame 2, and a feed hopper 3 and a discharge channel 4 are respectively provided on the left and right bottom sides of the top of the drying tank 1. A drive shaft 5 and a threaded blade 6 for entraining and conveying feed additives are installed inside the drying tank 1. The drive shaft 5 consists of a motor part fixedly installed on the left outer wall of the drying tank 1 and a shaft part rotating inside the drying tank 1. The threaded blade 6 is fixedly connected to the outer wall of the shaft of the drive shaft 5. The interior of the drying tank 1 is lined with... The system is equipped with an outer drying tube 7 that is evenly distributed around the circumference, and an inner drying tube 8 that is also evenly laid on the outer wall of the drive shaft 5 and the surface of the threaded blades 6, forming a dual low-temperature drying system. The outer drying tube 7 and the inner drying tube 8 are uniformly controlled by the control terminal system and precisely maintained within a low temperature range. Both sides of each tube of the outer drying tube 7 and the inner drying tube 8 are connected to the end ring tube for equal heat conduction and precise temperature control of each tube, thereby achieving precise and uniform low-temperature drying. This can effectively protect the active ingredients in the feed additives, thereby ensuring the effectiveness and stability of the feed additives.

[0027] The outer drying pipe 7 and the inner drying pipe 8 are precisely controlled within a low temperature range by the control terminal system, which can achieve low-temperature drying of feed additives. This ensures that the active ingredients of heat-sensitive additive raw materials (such as enzymes, vitamins, probiotics, etc.) are not destroyed, thus guaranteeing the functionality and effectiveness of the additives. When the feed additives are put into the drying tank 1, the drive shaft 5 and the threaded blades 6 rotate and continuously tumble and convey the feed additives. Since the outer drying pipe 7 and the inner drying pipe 8 are evenly laid on the drying tank 1, the drive shaft 5, and the threaded blades 6, the heat source generated can be concentrated and contacted with the tumbling feed additives from all directions, which accelerates heat exchange, improves heat conduction efficiency, shortens drying time, reduces energy consumption, and lowers production costs.

[0028] The inner drying tube 8 on the outer side of the drive shaft 5 is evenly laid around the outer wall of its shaft. The inner drying tube 8 on the surface of the threaded blade 6 has a threaded structure consistent with its torsion size and is also evenly laid from the inside to the outside on the surface of the threaded blade 6. This allows the drive shaft 5 to drive the threaded blade 6 to rotate, so that the feed additive can be fully tumbled and dispersed during the drying process and fully contact the heating surface of the inner drying tube 8. This achieves a uniform low-temperature drying effect, avoids local overheating or uneven drying, and helps maintain the quality stability and integrity of the active ingredients of the feed additive.

[0029] Example 2: Based on Example 1, the discharge port at the discharge channel 4 is sealed by a sealing plate 9. A cylinder 10 is fixedly installed on the outer right side of the drying tank 1, and the bottom output end of the cylinder 10 is fixedly connected to the sealing plate 9. A humidity monitor 19 is fixedly installed on the inner right side of the drying tank 1, and the humidity monitor 19 is electrically connected to the cylinder 10. The humidity monitor 19 monitors the humidity inside the drying tank 1 in real time, thereby sensing the degree of drying of the feed additive. When the humidity drops to the required range, the humidity monitor 19 will detect the humidity level. The power signal is sent to the control terminal system to start the operation of the control cylinder 10. The cylinder 10 drives the sealing plate 9 to rise, exposing the discharge port, thereby realizing the discharge of feed additives. In addition, a stabilizing plate 11 is fixedly connected to the right outer wall of the drying tank 1, and stabilizing vertical rods 12 are fixedly connected between the bottom two ends of the stabilizing plate 11 and the discharge channel 4. The top two ends of the sealing plate 9 are formed with protruding plates, and the protruding plates are slidably connected to the outside of the two stabilizing vertical rods 12, so as to vertically limit the sealing plate 9 when the cylinder 10 drives it to rise and fall, so as to ensure the stability of the rise and fall.

[0030] The drying tank 1 is equipped with an anti-residue component inside and on its right side. The anti-residue component includes a mounting ring 13 located on the left side inside the drying tank 1. A scraper 14 is fixedly bonded to the outer side of the mounting ring 13, and the outer wall of the scraper 14 is flush with the inner wall of the drying tank 1. A threaded rod 15 is threaded to one end of the inner side of the mounting ring 13, and the right side of the threaded rod 15 extends to the outside of the drying tank 1 and is fixedly connected to a gear 16. A rack 17 is fixedly connected to one end of the sealing plate 9, and the rack 17 and gear 16 are aligned. The meshing mechanism, through the inclusion of an anti-residue component, ensures that when the cylinder 10 drives the sealing plate 9 to rise for material discharge, the rack 17 rises synchronously, driving the gear 16 to rotate. The threaded rod 15 rotates synchronously, causing the mounting ring 13 and scraper 14 to move to the right. In this way, the scraper 14 can clean the feed additives adhering to the inner wall of the drying tank 1, and the material is discharged through the drive shaft 5 and threaded blades 6. This effectively reduces the residue of feed additives, lowers the risk of cross-contamination, and ensures the cleanliness of the feed additive production process.

[0031] In addition, the outer wall of the threaded rod 15 is formed with a limiting protrusion, and the limiting protrusion is attached to the right side wall of the drying tank 1 with the gear 16. The rack 17 has an L-shaped plate structure and is attached to the right side of the gear 16. By setting the above structure, the threaded rod 15 can be stably limited in the horizontal direction to prevent it from deviating. The inner wall of the drying tank 1 is fixedly connected with a stabilizing crossbar 18, and one end of the mounting ring frame 13 is slidably connected to the outside of the stabilizing crossbar 18, so that the threaded rod 15 can drive the mounting ring frame 13 and scraper 14 to move more stably.
