Description

Technical Field

[0001] This utility model belongs to the field of daily chemical equipment, and in particular relates to a vacuum distillation device for extracting jasmine components. Background Technology

[0002] Jasmine extract is a commonly used additive, widely used in perfumes, daily chemical products, and the food industry. Existing jasmine extract extraction equipment mainly includes traditional distillation furnaces, multi-stage distillation devices, and temperature-controlled distillation kettles. While these commonly used devices can meet basic distillation extraction requirements, they generally suffer from the following problems:

[0003] General-purpose equipment is not very targeted: Jasmine contains many heat-sensitive components, which can be destroyed during long-term or high-temperature distillation.

[0004] Existing multistage distillation apparatuses are complex in structure: although multistage distillation apparatuses can solve the problem of incomplete distillation, they themselves consist of multiple distillers connected in series, thus occupying a large area and are not suitable for small factories or laboratories.

[0005] In summary, to address the problems of existing extraction devices and improve the extraction rate and application limitations of jasmine components, the applicant has designed a vacuum distillation device for jasmine component extraction. Utility Model Content

[0006] The purpose of this invention is to provide a vacuum distillation apparatus for extracting components from jasmine flowers, thereby solving the problems mentioned in the background art. To achieve this purpose, the specific technical solution is as follows:

[0007] A vacuum distillation apparatus for extracting jasmine components includes a distillation kettle, a separator, and a collection bottle. It also includes a vacuum check valve, a vacuum pump, a primary condenser assembly, and a secondary condenser assembly. The top side of the distillation kettle is connected to the inlets of the primary condenser assembly via a branch pipe connector. The vapor outlets of the primary condenser assembly are connected to the inlets of the secondary condenser assembly via branch pipe connectors. The outlets of the secondary condenser are connected to the inlet of the separator via pipes. The liquid phase outlet of the separator is connected to the collection bottle. The gas phase outlet of the separator is connected to the side of the distillation kettle via a reflux pipe. A vacuum pump is installed on the top of the distillation kettle, and the pump's suction pipe is connected to the inside of the distillation kettle. Vacuum check valves are installed at the pressure relief ports of the collection bottle and the separator, respectively.

[0008] Furthermore, the primary condenser assembly consists of multiple spiral condenser tubes.

[0009] Furthermore, the secondary condenser is a spiral condenser.

[0010] The beneficial effects of this utility model are:

[0011] (1) This utility model creates a vacuum distillation environment by adding a vacuum check valve and a vacuum pump. The vacuum environment significantly reduces the boiling point (e.g., the boiling point of jasmine essential oil can be reduced from 200℃ to below 50℃), avoiding the oxidative decomposition of heat-sensitive aromatic substances (e.g., linalool, benzyl acetate) and preserving the complete aroma molecules.

[0012] (2) This invention employs a multi-stage condensation reflux method to maximize the extraction of effective components from jasmine flowers. The first-stage condenser consists of multiple sets of spiral condenser tubes, which are simultaneously connected to steam through a branch pipe joint, thereby increasing the steam throughput, improving distillation efficiency, and increasing the extraction purity by 20%-30%.
