Description

Technical Field

[0001] The utility model relates to the field of purification devices, in particular to a purification device combining a nitrogen filling system with a centrifugal dehydrator. Background Art

[0002] Many natural and synthetic fragrances are produced as solids. Crystallization is often the final step in the production process and a critical step in ensuring the quality of solid fragrance products. Therefore, the application of crystallization and purification technology in fragrance production has received widespread attention. Solution crystallization, as a method of fragrance crystallization, is widely used in fragrance production. Solution crystallization refers to the process of supersaturating a solution through cooling and solvent evaporation, thereby allowing the solute to precipitate from the solution. Currently, solution crystallization is widely used in industry for fragrance separation and purification, often using lower alcohols or ketones such as ethanol and acetone as solvents. The crude fragrance is dissolved in the solvent at high temperature in a specific proportion. The solution is then cooled and crystallized while standing or stirring. Finally, the solvent is removed by centrifugation to separate the solid, which is then dried to obtain the fine fragrance. For example, the solvent used in the crystallization and purification of heliotropin, thymol, and musk deodorant is ethanol. Two to three cycles of cooling, crystallization, centrifugation (desolvation), and airing ensure high product purity and yield. The purification of the above-mentioned crystalline spices mostly uses a centrifugal dehydrator as a solvent and impurity removal device, and after treatment, a reliable quality product can be obtained. However, for a few crystalline spices with unstable chemical properties, discoloration or oxidation is prone to occur during the centrifugation process, which in turn affects the purity and quality of the product. Therefore, a purification device that combines a nitrogen filling system with a centrifugal dehydrator is required.

[0003] The existing nitrogen filling system and the centrifugal dehydrator are used in conjunction with the purification device. When used, it is inconvenient to purify the chemically unstable crystalline spices, which causes the crystalline spices to change color during the purification process. Therefore, there is an urgent need for a nitrogen filling system and the centrifugal dehydrator are used in conjunction with the purification device. Utility Model Content
