Existing dryers have unstable hot air temperatures when drying compound prebiotic raw materials, resulting in unstable product quality. Furthermore, the atomized particles tend to accumulate at the top of the spiral pipe after drying, causing blockages, increasing cleaning difficulty, and affecting production efficiency.
The system employs a horizontally rotatable annular pipe assembly. The rotation of the annular pipe reduces the density of atomized particles in the same location, thereby lowering the risk of clogging. After production is completed, the particles are shaken off by rotating the annular pipe in both directions, achieving automatic cleaning.
It improves drying efficiency and product quality, reduces the risk of clogging, reduces cleaning difficulty, and ensures the continuity and stability of production.

[0017] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0018] like Figure 1-2 As shown, a drying device for compound prebiotic raw materials includes a housing 1. An atomizing nozzle 11 for atomizing the compound prebiotic raw materials is located at the top of the inner chamber of the housing 1. This atomizing nozzle 11 is existing technology and can atomize the liquid compound prebiotic raw materials into tiny particles for more uniform heating and drying, forming compound prebiotic particles. Below the atomizing nozzle 11 is a horizontally rotatable annular pipe assembly 2. The rotation of the annular pipe assembly allows hot air to be more evenly distributed inside the housing 1, drying the compound prebiotic raw materials and improving drying efficiency and quality. The annular pipe assembly 2 includes multiple coaxially arranged and sequentially arranged annular pipes 21, which are interconnected by connecting pipes. The annular tube 21 is connected to form a continuous hot air conveying channel. Several air outlets 211 for conveying hot air are provided on the top side of the annular tube 21. These air outlets 211 are evenly distributed to ensure that the hot air can evenly dry the atomized compound prebiotic raw materials. When the annular tube rotates, it can reduce the residence density of the dried atomized particles at the same point in the annular tube, thereby reducing the accumulation of dried atomized particles and reducing the risk of clogging the air outlets of the annular tube. At the same time, after the production is completed, the annular tube can be driven to rotate in both directions, thereby shaking off the atomized compound prebiotic particles accumulated on the top surface of the annular tube, minimizing the accumulation of atomized compound prebiotic particles and achieving an automatic cleaning effect.
[0019] like Figure 2 As shown, a gas supply pipe 22 for delivering external hot air into the annular pipe 21 is provided below the annular pipe assembly 2. A vent seat 23 is provided at the end of the gas supply pipe 22. The vent seat 23 serves to support and fix the gas supply pipe 22, while ensuring that the hot air can smoothly enter the annular pipe assembly 2. A fixed seat 24 is provided at the top of the vent seat 23, which can rotate relative to the vent seat 23 and is located at the center of the enclosure of the annular pipe 21. The vent seat supports the fixed seat, so that the fixed seat can rotate with the rotation of the annular pipe assembly and maintain the gas supply function.
[0020] like Figure 1-2As shown, the outer wall of the box 1 is provided with a hot air chamber 4 for producing hot air. The hot air chamber 4 is equipped with heating elements (such as electric heating wires, burners, or water heaters) to heat the air by combustion or electric heating. One end of the air supply pipe 22 is connected to the ventilation chamber 231, and the other end is connected to the hot air chamber 4 to form a stable supply of hot air. The hot air chamber 4 is provided with an air delivery pipe 41 that extends toward the top of the box 1 and is connected to the box 1. The air delivery pipe 41 serves as a flow channel for hot air and works in conjunction with the air supply pipe to allow hot air to circulate between the box and the hot air chamber during the drying process, so as to ensure the stability of the drying temperature of the compound prebiotic liquid in the box.
[0021] During operation, the compound prebiotic raw material is fed into the chamber 1 and atomized through the atomizing nozzle 11. At the same time, the hot air generated by the hot air chamber 4 enters the annular pipeline group 2 through the air supply pipe 22 and dries the atomized compound prebiotic raw material evenly through the air outlet 211. The annular pipeline group rotates synchronously. As the annular pipeline group 2 rotates continuously, the uniformity of the hot air in the chamber is maintained, so that the atomized compound prebiotic raw material can be heated and dried more fully. Finally, the dried compound prebiotic raw material particles accumulate at the bottom of the chamber and can be discharged from the bottom of the chamber 1, completing the entire drying process.
[0022] like Figure 2 As shown, a ventilation chamber 231 is formed by the interconnection between the ventilation seat 23 and the fixed seat 24. The fixed seat 24 is sleeved on the upper part of the ventilation seat 23. The fixed seat 24 and the ventilation seat 23 are connected by an oil-impregnated bearing 241. The top of the fixed seat 24 is provided with a dome 242. The dome 242 is provided with multiple exhaust holes 243 that communicate with the ventilation chamber 231. The ventilation chamber 231 is connected to each annular pipe 21 through at least one connecting pipe. Hot air enters the annular pipe group through the air supply pipe and enters each annular pipe. The oil-impregnated bearing is existing technology and will not be described in detail here. The dome on the top of the fixed seat is designed to facilitate the flow of the dried composite prebiotic particles and avoid the accumulation of composite prebiotic particles. The hot air entering the annular pipe and the hot air in the ventilation chamber are discharged upward from the air outlet and exhaust hole, respectively.
[0023] like Figure 2-3As shown, a drive ring 31 is provided around the outermost annular tube 21. A first arc-shaped gripper 32, which engages with the sidewall of the outermost annular tube 21, is located inside the drive ring 31. Above the first arc-shaped gripper 32, a second arc-shaped gripper 33 is provided, rotatably connected to and engaging with the first arc-shaped gripper 32 to clamp the annular tube 21. The first and second arc-shaped grippers cooperate to clamp and fix the outermost annular tube, allowing the drive ring to rotate synchronously with the annular tube assembly, facilitating disassembly, maintenance, and cleaning. An annular toothed assembly 311 is provided on the outer wall of the drive ring 31, and an annular track 312 is provided at the bottom of the drive ring 31. The inner wall of the housing 1 is provided with a toothed assembly 311 that engages with the drive ring. The guide groove 15 of the ring 31 and the annular track 312 are engaged. The annular gear 311 is provided with a transmission gear 34 that meshes with the annular gear 311 on the adjacent side. The side wall of the housing 1 is provided with a slot 12 for the transmission gear 34 to pass through. The outer wall of the housing 1 is provided with a drive motor 13 for driving the transmission gear 34 and a fixed housing 14 that surrounds and fixes the drive motor 13 and the transmission gear 34. The drive motor and the transmission gear are fixed in the fixed housing. The drive motor can drive the transmission gear to rotate. When the transmission gear rotates, it passes through the slot and meshes with the annular gear, thereby driving the drive ring to rotate synchronously and slowly. The drive ring is located in the guide groove and is maintained in a stable rotational motion by the guide limit of the annular track.
[0024] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
