Description

Technical Field

[0001] This utility model relates to the field of anise oil extraction technology, and in particular to a vacuum star anise drying and anise oil extraction device. Background Technology

[0002] Star anise is the fruit of the star anise tree, scientifically known as Illicium verum. It is purplish-brown in color, eight-pointed in shape, resembling a star, and has a sweet taste and a strong aromatic odor, the aroma coming from the volatile anisaldehyde. The fruit and seeds of star anise can be used as a seasoning, in medicine, and industrially as raw materials for perfumes, toothpaste, soaps, and cosmetics. After harvesting, star anise fruit still contains moisture and is prone to spoilage, mold, and rot; therefore, it must be processed promptly.

[0003] In existing star anise drying and fennel oil extraction devices, star anise is pulverized during drying and then transported to an evaporator for stirring to accelerate drying. During extraction, an organic solvent is added and stirred to mix the star anise and solvent, thus improving extraction efficiency. However, existing methods typically use unidirectional stirring, which can lead to localized overheating during drying, significantly reducing the quality of the dried star anise and resulting in uneven mixing of the pulverized star anise and organic solvent, further reducing extraction efficiency. Therefore, we propose a vacuum-type star anise drying and fennel oil extraction device to address this problem. Utility Model Content

[0026] In this embodiment, during use, the star anise is fed into the pulverizing chamber 19 by removing the sealing cover 20. Then, the second motor 15 is started, which drives the pulverizing blade 18 to rotate, pulverizing the star anise. The pulverized star anise is then fed into the tank 1, where the sealing cover 20 is replaced. The vacuum pump 25 is then started, and the air inside the tank 1 is expelled through the suction pipe 26 and exhaust pipe 27, thereby lowering the boiling point of the star anise. The electric heating wire 14 is then activated to heat the star anise inside the tank 1. Simultaneously, the first motor 2 is started... The stirring shaft 3 starts to rotate, which in turn drives the first stirring plate 9, which is fixed to the stirring shaft 3, to rotate. Simultaneously, the stirring shaft 3 drives the first bevel gear 4 to rotate, which in turn drives the second bevel gear 5, which meshes with the first bevel gear 4, to rotate.

When the dried star anise... After extraction, the heating wire 14 is turned off to stop the star anise from heating. At this time, the organic solution is transported into the tank 1 through the inlet pipe 22 by removing the sealing plug 23, and then the sealing plug 23 is replaced. The vacuum pump 25 is then started again to extract the air from the tank 1. At the same time, the first motor 2 is activated, so that the first stirring plate 9 and the second stirring plate 10 can achieve bidirectional stirring, making the crushed star anise and organic solvent mix more evenly, thereby greatly improving the extraction efficiency. After extraction is completed, the first control valve 29 is activated to transport the extracted anise oil in the tank 1 to the storage tank through the discharge pipe 28. Inside the material bin 30, the fennel oil is filtered through the filter box 31 to make it cleaner. At this time, by opening the second control valve 39, the filtered fennel oil is transported out of the filter box 31 through the discharge pipe 38 for collection and storage. When it is necessary to clean the filter box 31, the pressure plate 34 is pulled to move the insertion rod 35, causing the insertion rod 35 to disengage from the inside of the filter box 31. This removes the connection between the filter box 31 and the storage bin 30, making it easier to pull the filter box 31 out of the storage bin 30 by pulling the handle 32, thus facilitating the cleaning of the filter box 31.
