A device for extracting star anise oil with negative pressure circulating water

Abstract

The invention discloses a device of using negative-pressure circulating water to extract star anise oil. A distillation tank, two condensers, two tail gas tanks, an oil collector, two clocks, three oil-water separators, a liquid collection tank, a steam pot, a vacuum device and an automatic control valve are arranged, and the distillation tank is a vertical quick-to-open distillation tank with a deslagging end socket. The device is low in investment and reasonable in structure, and hot condensed water after being heated is enabled to flow into a heating tank from the deslagging end socket through a patterned plate to heat anise to form medium continuous circulating flow, so that extracted materials are ensured to be uniformly heated, continuous circulation and negative-pressure distillation are realized, distillation temperature can be lowered, extraction efficiency and product yield are greatly improved, and product quality is guaranteed; each of a deslagging mechanism, a charging port and a steam pipe is of a quick-mounting structure, so that convenience is brought to charging, deslagging, connecting and maintaining, process operation is easy, extraction effect is good, distillation time is short, energy resources are saved, safety and reliability are realized, and the device has remarkable economic benefit and social benefit.

Description

technical field [0001] The present invention relates to an essential oil extraction device, especially a device for extracting star anise oil with negative pressure circulating water, belonging to the field of mechanical technology. Background technique [0002] At present, the extraction of effective components of star anise oil mostly follows the methods of decoction, steam distillation and organic solvent extraction. In the prior art, the decoction method and steam distillation method are difficult to feed and discharge materials, and use boiler steam to separate a lot of condensed water. The separation of oil and water requires a lot of separation equipment and occupies a large area. Atmospheric distillation, the yield of star anise oil is low, the quality is difficult to guarantee, and the heat energy of the separated condensed water is not fully utilized, the production cost is high, and it has always been difficult for large-scale industrial production. The aroma of ...
