[0032] Seabuckthorn yellow pigment is a natural pigment extracted from seabuckthorn fruit, mainly found in the skin and pulp of seabuckthorn fruit. The rich carotenoid content of seabuckthorn fruit makes it an important raw material for extracting seabuckthorn yellow pigment. The extraction process of seabuckthorn yellow pigment directly affects its quality and stability. By optimizing the drying device, seabuckthorn yellow pigment can be effectively protected during the extraction process.
[0033] In order to further improve the drying of sea buckthorn fruit, the specific operations are as follows:
[0034] When drying, traditional drying devices stir-fry the sea buckthorn fruit to make it heat more evenly. However, the sea buckthorn fruit will be damaged during the stir-frying process. When the skin of the sea buckthorn fruit is damaged, it will first cause contamination of the fruit body and secondly cause pollutants to enter the interior of the fruit body.
[0035] The casing 11 is embedded with a tumbling assembly 4, which includes a tumbling frame 41, which is embedded in the casing 11, and a driving roller 42 is arranged directly above the tumbling frame 41. There are two sets of tumbling frames 41 and driving rollers 42, and the two sets of tumbling frames 41 and driving rollers 42 are symmetrically arranged in the casing 11. An alternative frame 43 is also installed in the casing 11, and an alternative roller 44 is installed on the upper surface of the alternative frame 43. There are also two sets of alternative frames 43 and alternative rollers 44, and the driving rollers 42 and the alternative rollers 44 are provided with spiral protrusions. The driving rollers 42 and the alternative rollers 44 are driven to rotate by a micro motor, and the alternative frames 43 and the alternative rollers 44 are arranged between the tumbling frames 41 and the driving rollers 42. Below, the rolling rack 41 and the alternative rack 43 are tiltedly arranged inside the casing 11, the rolling rack 41 and the alternative rack 43 have a higher height on one side close to the feed trough 12 and a lower height on the side away from the feed trough 12, and the sea buckthorn fruits are placed between two groups of rolling racks 41 or two groups of alternative racks 43, the rolling rack 41 and the alternative rack 43 have a side close to the feed trough 12 as a starting point, the spacing between the starting points of the two groups of rolling racks 41 is small, the rolling rack 41 and the alternative rack 43 have a side away from the feed trough 12 as a diverging point, the spacing between the diverging points of the two groups of rolling racks 41 is large, the spacing between the starting points of the two groups of rolling racks 41 is larger than the spacing between the starting points of the alternative racks 43, and the spacing between the diverging points of the rolling racks 41 is larger than the spacing between the diverging points of the alternative racks 43.
[0036] An air outlet duct 2 is embedded in the casing 11 . The air outlet duct 2 penetrates the outer wall of the casing 11 and is embedded in the casing 11 . The air outlet duct 2 is located between the tumbling frame 41 and the optional frame 43 .
[0037] The ends of the rolling frame 41 and the alternative frame 43 are connected to a back plate 45, and a driving roller 42 is connected to one side of the back plate 45. The driving roller 42 and the back plate 45 are rotationally connected, and the driving roller 42 and the alternative roller 44 pass through the interior of the back plate 45. The driving roller 42 and the alternative roller 44 are connected to a micro motor.
[0038] In order to solve this problem, a tumbling assembly 4 is provided to prevent the fruit body from being damaged during drying. The sea buckthorn fruit is placed on the feed trough 12. The feed trough 12 is tilted so that the sea buckthorn fruit can be poured into the interior of the casing 11. The sea buckthorn fruit falls between the two groups of tumbling frames 41, and the sea buckthorn fruit is supported by the tumbling frames 41. Since the tumbling frames 41 are tilted, the sea buckthorn fruit on the tumbling frames 41 will slowly roll downwards, and the rolling of the sea buckthorn fruit replaces the traditional stir-frying. The epidermis will not be damaged during the rolling stage, which will greatly protect the integrity of the sea buckthorn fruit. During the drying process, the hot air is blown downwards by the top machine chamber 13. The hot air enters the interior of the casing 11 and dries the sea buckthorn fruit at the upper end of the tumbling frame 41. As the sea buckthorn fruit rolls on the tumbling frame 41, different surfaces of the sea buckthorn fruit can come into contact with the hot air to achieve drying. When the fruit body is drying, as the internal moisture is continuously lost, the mass of the fruit body will become smaller. When the particle size of the reduced sea buckthorn fruit is smaller than the spacing between the two sets of tumbling frames 41, it cannot be supported by the tumbling frame 41. At this time, the sea buckthorn fruit will fall between the two sets of alternative frames 43, and the two sets of alternative frames 43 will continue to drive the sea buckthorn fruit to roll on its surface until it is dried and transported out of the interior of the casing 11 from the alternative frames 43.
[0039] In order to allow the sea buckthorn fruits to roll on the tumbling frame 41 or the alternative frame 43 after drying, a driving roller 42 and an alternative roller 44 are provided, and the sea buckthorn fruits are placed on the driving roller 42 and the alternative roller 44. The rotation of the driving roller 42 and the alternative roller 44 drives the rotation of the sea buckthorn fruits. When the sea buckthorn fruits are rotating, the tumbling frame 41 and the alternative frame 43 are tilted downward, so the alternative frame 43 and the alternative roller 44 drive the sea buckthorn fruits to roll.
[0040] In addition, the driving roller 42 and the optional roller 44 are also provided with spiral protrusions, which can push the sea buckthorn fruits forward when rotating until they are dried and pushed out of the housing 11.
[0041] Through such a design, first of all, the sea buckthorn fruit can be prevented from being damaged during the drying process, ensuring the integrity of the fruit after drying. This can also prevent the yellow pigment in the fruit from being contaminated. In addition, during the drying process, the fruit body is guaranteed to roll, making the drying of the fruit body more complete and improving the drying efficiency.
[0042] In addition, by setting up the rolling frame 41 and the alternative frame 43, fruit bodies of different sizes can be classified. For example, some large-grained sea buckthorn fruits whose particle size is larger than the spacing between the rolling frames 41 can be supported on the rolling frame 41. When some sea buckthorn fruits have a smaller particle size, they cannot be supported between the rolling frames 41. Such sea buckthorn fruits will be supported by the alternative frame 43, thus realizing the separation of sea buckthorn fruit particle sizes. The moisture content of sea buckthorn fruits of different particle sizes is also inconsistent. In order to better dry the sea buckthorn fruit, the temperature inside the top machine compartment 13 is higher, so the hot air blown out can also dry the fruit bodies with larger particle sizes more effectively. The fruit bodies on the alternative frame 43 are smaller and contain less moisture inside, so they can be dried at a temperature lower than that in the top machine compartment 13.
[0043] A ventilation groove is provided inside the housing 11, and a guide assembly 3 is embedded inside the ventilation groove. The guide assembly 3 includes a guide piece 31, and an anti-reverse piece 32 is connected to one side of the bottom end of the guide piece 31. The guide piece 31 and the anti-reverse piece 32 are rotatably connected. The top end of the guide piece 31 is arranged in an arc shape, and a set of cut corners are arranged at the bottom end of the guide piece 31. The bottom end width of the guide piece 31 is smaller than the top end width.
[0044] When hot air is blown into the bottom machine compartment 14, the airflow will blow up the anti-reversal sheet 32. At this time, the anti-reversal sheet 32 and the guide sheet 31 form an eight-shaped angle, which inhibits the hot air flow from continuing to rise and plays a role in blocking the hot air flow from rising.
[0045] The hot air blower inside the top machine compartment 13 transports the hot air vertically downward to the inside of the casing 11, and the hot air blower arranged inside the bottom machine compartment 14 transports the hot air vertically upward to the inside of the casing 11. The hot air entering the inside of the casing 11 is discharged through the air outlet pipe 2.
[0046] During drying, in order to improve the exchange of internal airflow, hot air is blown downward through the top machine chamber 13, and hot air is blown upward through the bottom machine chamber 14. In this way, when the two streams of hot air contact the sea buckthorn fruits on the rolling rack 41 and the optional rack 43, the two streams of air will collide. The collision of the two streams of air can produce a turbulent effect, increase the contact area and contact frequency between the airflow and the surface of the sea buckthorn fruit, thereby improving the heat transfer efficiency. This design helps to evaporate the water in the sea buckthorn fruit more quickly and evenly, shortening the drying time. In addition, the turbulence generated by the collision of airflows can break the local temperature gradient that may occur during the drying process, so that the heat received by each part of the sea buckthorn fruit is more uniform. This helps to avoid local overheating or uneven drying, and improves the quality of the dried sea buckthorn fruit.
[0047] The airflow after collision is discharged through the air outlet pipe 2 at the same height, which can form an effective moisture removal channel. As the drying process proceeds, the moisture in the seabuckthorn fruit is continuously evaporated and discharged with the airflow, maintaining a low humidity state in the dry environment, which is conducive to further evaporation of moisture.
[0048] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
