Apparatus for cyclic water extraction of cassia oil under reduced pressure

Abstract

The invention relates to an apparatus for cyclic water extraction of cassia oil under reduced pressure, comprising a distilling tank, two condensers, two tail gas tanks, three oil-water separators, an oil collector, a liquid collection tank, a heating pot, and a vacuum device; the distilling tank is a vertical sandwiched distilling tank, upper and lower heads are quick-opening heads, and two view clocks are provided. The apparatus is low in investment and reasonable in structure; hot condensate can be heated, steam flows through a perforated plate into a heating tank from a residue discharge head so as to heat cassia bark, a medium flows from bottom to top continuously and cyclically, it is guaranteed that all extracted materials can be evenly heated, continuous cyclic distillation under reduced pressure is achieved, extraction efficiency and production yield can be greatly increased, and product quality is guaranteed; a residue discharge mechanism, a feeding port and a steam pipe are each of quick-fitting structure, feeding, residue discharging, connecting and maintenance are facilitated; the process is easy to perform, extraction is effective, short time is taken, energy is saved, and the apparatus is good in safety and reliability and has significant economic and social benefits.

Description

technical field [0001] The invention relates to an essential oil extraction device, in particular to a device for extracting cinnamon oil with decompressed circulating water, belonging to the field of mechanical technology. Background technique [0002] At present, the extraction of effective components of cinnamon is mostly carried out by 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 cinnamon oil is low, and the quality is difficult to guarantee. In addition, the heat energy of the separated condensed water is not fully utilized, and the production cost is high, which has always been difficult for large-scale industrial production. The aroma of cinna...
