Problems solved by technology

[0004] The steam distillation method has the characteristics of mature technology, low equipment cost, and stable system operation. In addition, no organic solvents are added in the distillation extraction process, and the entire extraction process is non-polluting to the human body and the environment. The extraction rate of essential oil is low, and the waste heat of vetiver oil steam condensation is not recycled, which results in high energy consumption

Abstract

The invention relates to an energy-saving vetiver oil extraction system, belonging to the technical field of pharmaceutical chemicals and energy conservation. The energy-saving vetiver grass oil extraction system disclosed by the invention comprises a distillation part and a condensation and waste heat recovery part, wherein the distillation part comprises a steam boiler, a jet compressor and a rotary drum type distillation still; and the condensation and waste heat recovery part comprises a plate type evaporator, a plate type preheater, a plate type cooler, an oil-water separator, a low-pressure steam pocket, a forced circulation pump, a flow regulating valve, a pressure reducing valve, a stop valve, a water feeding pump, a cooling tower and a circulating water pump. According to the energy-saving vetiver grass oil extraction system, a traditional essential oil steam distillation technology is optimized, improved and an energy-saving design is adopted, so an essential oil extraction rate is increased, multi-stage utilization of waste heat is achieved, and process energy consumption is reduced.

Description

technical field [0001] The invention relates to an energy-saving system for extracting vetiver oil, belonging to the technical fields of medicine, chemical industry and energy conservation. Background technique [0002] Vetiver (Vetiveria zizantoides (Linn.) Nash), also known as Vetiver and Pedigrass, belongs to the Gramineae (Poaceae) genus Vetiver, a perennial stout herb. It is widely planted from tropical Africa to India, Sri Lanka, Thailand, Myanmar, Indonesia, and Malaysia; it is introduced in Jiangsu, Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Yunnan, Hainan, and Sichuan in China. Shaanxi, Gansu, Ningxia, Xinjiang, Qinghai, Tibet, Guizhou and other provinces are currently expanding the scale of introduction. The whole body of vetiver is a treasure, and its root can emit a pleasant fragrance. The extracted essential oil is widely used in the perfume and cosmetic industry because of its fresh and pleasant taste. It is the most important natural flavoring agent and st...
