Description
Technical Field
[0001] This utility model relates to the technical field of low-temperature drying equipment, specifically to a low-temperature drying equipment for chia seed powder production. Background Technology
[0002] Chia seed powder is highly regarded for its rich nutritional content, and the drying process plays a crucial role in product quality. Traditional chia seed powder drying techniques often employ methods such as hot air drying and vacuum drying. However, these methods have many drawbacks. During hot air drying, the high temperature environment can easily damage heat-sensitive nutrients in chia seed powder, such as unsaturated fatty acids and vitamins, leading to a reduction in the product's nutritional value. In recent years, to address the shortcomings of traditional drying methods, low-temperature drying technology has gradually been applied to chia seed powder production.
[0003] Most existing low-temperature drying devices achieve low-temperature drying by simply circulating air or static drying, which results in uneven drying. Due to the agglomeration of chia seed powder particles, the internal powder cannot fully contact the drying medium during static drying, leading to prolonged drying time and inconsistent product quality. Utility Model Content
[0004] Therefore, this utility model provides a low-temperature drying device for chia seed powder production. Through the low-temperature drying component, it solves the problem that most low-temperature drying devices achieve the purpose of low-temperature drying by simply circulating air or static drying, which results in uneven drying.

[0008] Preferably, the rotating disk is embedded in one side wall of the low-temperature drying oven and connected to the low-temperature drying oven via a bearing.
[0009] Preferably, the motor is fixedly connected to one side wall of the left connecting frame, the output end of the motor is fixedly connected to one end of the transmission shaft, and the transmission shaft passes through the two rotating disks and is fixedly connected to the two rotating disks.
[0010] Preferably, the drying and stirring component includes two fixed toothed rings, which are respectively fixedly connected to the outer two side walls of the low-temperature drying chamber, and the two fixed toothed rings are provided with two powder stirring components and two low-temperature jetting components inside.

[0013] Preferably, the pipe connection component includes a connection box, on one side of which two rotary pipe joints are fixedly connected. The two rotary pipe joints extend into the interior of two jet pipes and are connected to the two jet pipes respectively. On one side of the connection box, a rotary pipe joint is fixedly provided. One end of the rotary pipe joint extends into the interior of the air intake pipe and is connected to the air intake pipe. The air intake pipe passes through adjacent support plates and is fixedly connected to the two support plates.
[0014] The present invention has the following advantages:
[0015] The combined effect of the rotating jet pipe and the rotating stirring blades causes the chia seed powder to tumble inside the box, effectively breaking up powder agglomeration and ensuring that every part of the powder can fully contact the low-temperature dry air.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0027] See attached document Figure 1 - Appendix Figure 6 This utility model provides a low-temperature drying device for chia seed powder production, including a base 1, two support plates 2 fixedly mounted on the top of the base 1, a low-temperature drying component 3 between the two support plates 2, a right connecting frame 4 and a left connecting frame 6 fixedly connected to the two sides of the low-temperature drying component 3 respectively, a material pouring drive component 5 on one side of one of the support plates 2, a box cover 7 fixedly connected to the top of the low-temperature drying component 3, an exhaust filter body 8 fixedly mounted on the top of the box cover 7, the low-temperature drying component 3 includes a low-temperature drying box 31, rotating disks 32 are provided inside the two side walls of the low-temperature drying box 31, a motor 33 is provided on one side of one of the rotating disks 32, a drive shaft 34 is inserted between the two rotating disks 32, a drying and stirring component 35 is connected between the two rotating disks 32, a pipe connection component 36 is provided on one side of the drying and stirring component 35, and an air inlet pipe 37 is provided on one side of the pipe connection component 36.
[0028] In this embodiment, to achieve stirring and blowing low-temperature air into the chia seed powder during low-temperature drying, the low-temperature drying chamber 31 serves as the core working cavity. Its two side walls are connected to the transmission shaft 34 via a rotating disk 32, driven by a motor 33 to rotate the disk 32, providing a motion basis for the internal drying and stirring component 35. The fixed gear ring 351 in the drying and stirring component 35 is fixed to the external two side walls of the low-temperature drying chamber 31, forming an internal meshing transmission structure with gear one 352 and gear two 355. When the rotating disk 32 rotates, gear one 352 and gear two 355 rotate along the fixed gear ring 351, simultaneously rotating under meshing action. The air jet pipe 353 inserted inside gear one 352 rotates with gear one 352. The device rotates on its own axis, and the jet nozzles 354 evenly distributed on its outer wall spray low-temperature dry air onto the chia seed powder. The connecting box 361 of the pipe connecting component 36 is connected to the air inlet pipe 37 through the rotating pipe joint 363, so that the low-temperature dry air output from the cold air supply device is introduced into the connecting box 361, and then delivered to the two jet pipes 353 through the two rotating pipe joints 362 respectively. The stirring rod 356 inserted inside the gear 2 355 rotates synchronously, driving the externally fixed stirring blade 357 to continuously tumble and stir the chia seed powder. Under the multiple effects of jetting from the jet pipe 353 and stirring from the stirring blade 357, it is ensured that the chia seed powder in the box can fully contact the low-temperature dry air, thereby achieving a highly efficient and uniform low-temperature drying effect.
[0029] To achieve the purpose of unloading the chia seed powder after low-temperature drying, the device adopts the following technical solution: one side of the right connecting frame 4 and the left connecting frame 6 are fixedly connected to the low-temperature drying chamber 31, and the other end of the right connecting frame 4 and the left connecting frame 6 are respectively connected to the side wall of the two support plates 2 through bearings. The unloading drive component 5 includes a self-locking motor 51, which is fixedly connected to the adjacent support plate 2. The output end of the self-locking motor 51 is fixedly provided with a rotating shaft 52, which passes through the adjacent support plate 2 and is connected to the adjacent support plate 2 through bearings. One end of the rotating shaft 52 passes through the left connecting frame 6 and is fixedly connected to the left connecting frame 6. When the drying process is completed, the chamber cover 7 is opened, and the self-locking motor 51 is started again to control the low-temperature drying chamber 31 to tilt to the unloading angle. Under the action of gravity, the dried chia seed powder slides quickly down through the chamber opening to the collection container, completing the entire drying production process.
[0030] To achieve the purpose of low-temperature drying of chia seed powder inside the low-temperature drying chamber 31 by the operation of the drying and stirring component 35, the device adopts the following technical solution: A rotating disk 32 is embedded in one side wall of the low-temperature drying chamber 31 and connected to the chamber via a bearing; a motor 33 is fixedly connected to one side wall of the left connecting frame 6; the output end of the motor 33 is fixedly connected to one end of a transmission shaft 34; the transmission shaft 34 passes through two rotating disks 32 and is fixedly connected to both rotating disks 32; the drying and stirring component 35 includes two fixed gear rings 351, which are respectively fixedly connected to the outer two side walls of the low-temperature drying chamber 31; the two fixed gear rings 351 are equipped with two powder stirring components and two low-temperature air jet components; the powder stirring components include two gears 35... 2. Two gears 352 are located inside and mesh with two fixed gear rings 351. A jet pipe 353 is fixedly inserted inside each gear 352. Multiple jet heads 354 are fixedly installed outside the jet pipe 353. The jet pipe 353 passes through two rotating disks 32 and is connected to them via bearings. The cryogenic jetting component includes two gears 355. These gears 355 are located inside and mesh with two fixed gear rings 351. A stirring rod 356 is fixedly inserted inside each gear 355. Multiple stirring blades 357 are fixedly sleeved on the outside of the stirring rod 356. The stirring blades 357 pass through two rotating disks 32 and are connected to them via bearings. A pipe connection component 36 is also included. The system includes a connecting box 361. Two rotating pipe joints 362 are fixedly connected to one side of the connecting box 361. Each rotating pipe joint 362 extends into and connects to one of the two jet pipes 353. A second rotating pipe joint 363 is fixedly installed on one side of the connecting box 361. One end of the second rotating pipe joint 363 extends into and connects to the air inlet pipe 37. The air inlet pipe 37 passes through adjacent support plates 2 and is fixedly connected to both support plates 2. When the low-temperature drying operation starts, the self-locking motor 51 is activated first. Its output shaft 52 drives the left connecting frame 6, causing the low-temperature drying assembly 3 to rotate around the bearing fulcrum on the support plate 2. After precisely adjusting to the vertical working angle, the self-locking motor 51 automatically locks, ensuring the drying process is completed. During the stable operation of the equipment, the main drive motor 33 is then started. The output shaft of the motor 33 drives the transmission shaft 34 to rotate, which in turn drives the rotating disks 32 on both sides to rotate. The rotation of the rotating disks 32 drives the drying and stirring component 35 to operate. In this process, the drying and stirring component 35 achieves a dual stirring and drying function. The fixed gear ring 351, which is fixed to the outer wall of the low-temperature drying chamber 31, forms an internal meshing transmission structure with gear one 352 and gear two 355. When the drying and stirring component 35 rotates, gear one 352 rotates along the fixed gear ring 351 inside the fixed gear ring 351 and rotates through the meshing teeth, thereby driving the jet pipe 353 inserted inside the gear one 352 to rotate synchronously. The jet nozzles 354 evenly distributed on the outer wall of the jet pipe 353 rotate accordingly.Low-temperature dry air, input through air inlet pipe 37, is evenly sprayed into the chia seed powder pile. Simultaneously, gear two 355, under the same transmission mechanism, drives the stirring rod 356 to rotate. The stirring blades 357, distributed in a staggered pattern on the rod, tumble the powder, effectively breaking up material agglomeration and allowing the low-temperature dry air to penetrate into every gap in the powder, achieving all-round, dead-angle-free low-temperature drying.
[0031] The usage process of this utility model is as follows: When using this utility model, connect the external power supply to ensure a stable connection between the air inlet pipe 37 and the matching cold air supply device. The lid 7 is connected to the low-temperature drying oven 31 via a detachable structure. When drying chia seed powder, the lid 7 is separated from the low-temperature drying oven 31 via the detachable structure. The chia seed powder to be dried is poured into the low-temperature drying oven 31 through the top opening. After filling, the lid 7 is reset and sealed. When the low-temperature drying operation starts, the self-locking motor 51 is activated first. The rotating shaft 52 at its output end drives the left connecting frame 6, causing the low-temperature drying assembly 3 to rotate around the bearing fulcrum on the support plate 2. After precisely adjusting to the vertical working angle, the self-locking motor 51 automatically locks, ensuring the stable operation of the equipment during the drying process. The main drive motor 33 is started, and the output shaft of the motor 33 drives the transmission shaft 34 to rotate. The transmission shaft 34 drives the two rotating disks 32 to rotate. The rotation of the rotating disks 32 drives the drying and stirring component 35 to work. During this process, the drying and stirring component 35 realizes a dual stirring and drying function. The fixed gear ring 351 fixed to the outer wall of the low temperature drying chamber 31 forms an internal meshing transmission structure with gear one 352 and gear two 355. When the drying and stirring component 35 rotates, gear one 352 rotates along the fixed gear ring 351 inside the fixed gear ring 351 and rotates through the meshing teeth, thereby driving the jet pipe 353 inserted inside the gear one 352 to rotate synchronously. The jet heads 354 evenly distributed on the outer wall of the jet pipe 353 rotate accordingly, and the low temperature dry air input by the air inlet pipe 37 is rotated. The mixture is evenly sprayed into the chia seed powder pile. Simultaneously, gear 355, under the same transmission mechanism, drives the stirring rod 356 to rotate. The staggered stirring blades 357 on the rod agitate the powder, effectively breaking up material agglomeration and allowing low-temperature dry air to penetrate every gap in the powder, achieving all-round, no-dead-angle low-temperature drying. The pipe connection component 36 adopts a rotary sealing connection design, ensuring compatibility between gas delivery and equipment rotation (a rotary joint refers to a pipe connection device where the connected pipes can rotate relative to each other and can be used to convey various media such as gas, liquid, and oil). Its compact design and flange connection allow for effective integration into customer equipment; a rotary joint is a 360° rotating, sealed rotary connector for conveying media. The connection box 361 serves as a gas distribution... The equipment is equipped with a hub, where two rotating pipe joints 362, fixed to its side wall, connect to the jet pipe 353. This ensures airtightness while allowing the jet pipe 353 to rotate freely. Another rotating pipe joint 363 connects to the air inlet pipe 37, facilitating the stable introduction of low-temperature dry air generated by the cold air supply device into the connecting box 361. After being diverted by the internal guide cavity, the air is delivered to the two jet pipes 353 and finally ejected from the jet head 354. Throughout the entire conveying process, the multi-layered sealing rings and wear-resistant ceramic coating of the rotating pipe joints effectively prevent gas leakage and mechanical wear, ensuring long-term stable operation of the equipment. Moisture and exhaust gas carrying fine powder generated during the drying process are discharged through the exhaust filter body 8 at the top of the box cover 7, while simultaneously recovering the retained chia seed powder, reducing material loss.After the drying process is complete, open the lid 7 and restart the self-locking motor 51 to tilt the low-temperature drying chamber 31 to the unloading angle. The dried chia seed powder, under gravity, quickly slides down through the opening into the collection container, completing the entire drying process.
