[0002] Astaxanthin crystals are a substance with a unique structure and properties. It is a type of carotenoid and has a bright red color. In nature, it can be synthesized in some algae, shrimp, crabs, and other organisms. It possesses strong antioxidant properties, effectively scavenging free radicals, and is widely used in the health supplement, cosmetic, food, and feed additive industries to enhance product efficacy.

[0003] In existing technologies, some devices dry astaxanthin crystals in a clump-like manner, leading to low drying efficiency and long processing time. Therefore, an astaxanthin crystal drying device is proposed. Utility Model Content

[0004] This invention proposes an astaxanthin crystal drying device, which aims to improve the problem in some existing devices that cause astaxanthin crystals to pile up, resulting in low drying efficiency and long processing time.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A drying device for astaxanthin crystals includes a drying chamber. A glass groove is formed on the inner front wall of the drying chamber. Two heating wires are fixedly connected inside the drying chamber. A fan box is fixedly connected to the outside of the drying chamber. An air transfer groove is formed on the inner wall of the drying chamber near the fan box. An exhaust fan is fixedly connected inside the fan box. A sliding groove is formed on the inner rear wall of the drying chamber. Two connecting plates are fixedly connected to the outer rear side of the drying chamber. One of the connecting plates has a reciprocating assembly providing rotational capability on its exterior. A flat plate is fixedly connected to the exterior of the reciprocating assembly.

An outer box is fixedly connected to the bottom of the multiple sliding rods. The flat plate is slidably connected to the exterior of the sliding groove.

[0007] The above technical solution features a drying oven with an integrated glass tank for easy observation, a heating wire to provide basic heat, and a fan box with an exhaust fan that uses air ducts to introduce hot air to accelerate drying. The reciprocating assembly, combined with a flat plate, ensures that astaxanthin crystals are evenly distributed, improving drying efficiency and uniformity.

[0008] As a further description of the above technical solution:

[0022] The above technical solution involves preheating with heating wire two inside the drying cylinder, stirring with a stirring assembly, and a protective net to prevent crystals from falling.

[0028] The above technical solution, with its components working closely together, forms a highly efficient and continuous drying process for astaxanthin crystals, from feeding, pre-drying, leveling, vibration-assisted drying to discharging, which greatly improves production efficiency and product quality.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, starting the motor drives the threaded rod to rotate, and the transmission block reciprocates on the threaded rod. As the threaded rod rotates, the large drive wheel drives the small drive wheel to rotate via a belt, thus rotating the threaded conveyor rod and transferring the astaxanthin crystals to the receiving box. Simultaneously, the rotation of the threaded rod, through the connecting block and connecting shaft, drives the spreading plate to slide back and forth in the chute, flattening the astaxanthin crystals in the receiving box. Heating wires in the drying chamber further heat and dry the astaxanthin crystals, and the exhaust fan in the fan box blows air into the drying chamber through the air duct. This structure achieves the effect of flattening the astaxanthin crystals when they are conveyed to the receiving box, solving the problem of astaxanthin crystals piling up in some devices, leading to low drying efficiency and long processing time.

[0031] 2. In this invention, the second motor starts, driving the first rotating shaft and the cam to rotate. The cam rotation provides irregular rotational force, causing the sliding rod connected to the outer casing to slide up and down inside the placement slot under the elastic force provided by the spring, generating vibration. The astaxanthin crystals, which are flattened in the receiving box inside the outer casing, vibrate vertically and are suspended, which helps to dry the astaxanthin crystals and ensure uniform heating. This structure achieves a small-amplitude vibration effect on the astaxanthin crystals, solving the problem of insufficient drying when astaxanthin is left to stand still in some parts of the device.

The inner wall of the drying cylinder 35 is provided with multiple placement slots 36. Two heating wires 37 are fixedly connected inside the placement slots 36. The top of the drying cylinder 35 is provided with a stirring assembly that provides rotation capability. The stirring assembly includes a motor 38, a rotating shaft 39, and two heating stirring rods 40, which are fixed outside the rotating shaft 39.

A steam outlet pipe 44 is fixedly connected to the top of drying cylinder 35. Two sets of feet 45 are fixedly connected to the bottom of drying chamber 1.

[0048] Working principle: Astaxanthin crystals enter the drying cylinder 35 through the feed pipe 43. When the power is turned on, the heating wire 37 in the inner wall of the drying cylinder 35 (placed in slot 36) is activated for initial heating and drying. Simultaneously, the motor 38 starts, driving the rotating shaft 39 and the heating stirring rod 40 to rotate, stirring the astaxanthin crystals and accelerating the drying process. The generated water vapor is discharged through the steam outlet pipe 44. Since the contact surface of the initially dried astaxanthin crystals was not fully dried during stirring, the control valve 34 is opened. The initially dried astaxanthin crystals then enter the protective shell 32 through the discharge pipe 33, and then enter the receiving box 19 inside the drying chamber 1 through the discharge pipe 42.

[0049] Motor 8 starts, driving the threaded rod 25 to rotate. The transmission block 9 reciprocates on the threaded rod 25. As the threaded rod 25 rotates, the large drive wheel 31 drives the small drive wheel 28 to rotate via the belt 29, thereby rotating the threaded material transfer rod 27. This allows the astaxanthin crystals to be transferred to the receiving box 19. Simultaneously, the rotation of the threaded rod 25, through the connecting block 10 and connecting shaft 11, drives the spreading plate 12 to slide back and forth within the slide groove 6, flattening the astaxanthin crystals in the receiving box 19. Heating wire 3 in the drying chamber 1 further heats and dries the astaxanthin crystals. The exhaust fan 5 in the fan box 4 blows air into the drying chamber 1 through the air duct, accelerating airflow and improving drying efficiency without disturbing the astaxanthin crystals. Simultaneously, the exhaust fan 5 reverses direction to expel moisture from the device.

[0050] Motor 22 starts, driving rotating shaft 23 and cam 24 to rotate. The rotation of cam 24 provides irregular rotational force, causing sliding rod 14 connected to outer box 16 to slide up and down inside placement slot 13 under the elastic force provided by spring 15, generating vibration force. The astaxanthin crystals flattened in receiving box 19 inside outer box 16 vibrate vertically and suspended, which helps the astaxanthin crystals dry and be heated evenly. After drying, by pulling handle 21, receiving box 19 is pulled out of drying box 1 with the assistance of multiple rotating wheels 18, and the dried astaxanthin crystals are taken out.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
