Multifunctional volatile oil distilling and extracting tank

Abstract

The invention discloses a multifunctional volatile oil distilling and extracting tank, and belongs to the field of traditional Chinese medicine extracting equipment. The multifunctional volatile oil distilling and extracting tank comprises a tank body, a tank cap, a tank bottom and a steam supply system, and the tank cap is connected with an oil outlet pipe. The multifunctional volatile oil distilling and extracting tank is characterized in that the tank body is in the shape of a big-end-up cone, the tank body and the tank bottom adopt interlayers, steam is pumped into the interlayers, multiple layers of detachable separation plates are arranged in the tank body, and through holes are formed in the separation plates. The multifunctional volatile oil distilling and extracting tank can be used for extracting general medicinal oil and essential oil according to the routine and normal pressure, extracting high-boiling-point medicinal oil and essential oil containing aldehydes and alcohols at high temperature and high pressure, extracting medicinal oil and essential oil which are prone to volatilizing andloseand contain more alkenes in a vacuum decompression mode and extracting extracts, one tank has multiple purposes, distilling can be completed for one time, the equipment cost is saved, and the yield of the materials, especially volatile oil, is improved.

Description

technical field [0001] The invention relates to a device for extracting Chinese herbal medicines, in particular to a multifunctional volatile oil distillation extraction tank. Background technique [0002] Volatile oil is one of the main components of Chinese herbal medicines. The functional component of some medicinal materials is volatile oil, so it is necessary to use equipment to extract the volatile oil. At present, there are many methods for extracting volatile oil, mainly steam distillation, solvent reflux, microwave, CO 2 Supercritical fluid extraction, in which steam distillation, CO 2 Supercritical extraction is the most commonly used method, CO 2 Supercritical extraction of volatile oils from plants can prevent the destruction of easily pyrolyzed components in the volatile oils compared with steam distillation, improve product quality, and increase yield at the same time, but the equipment is expensive and the cost is high; After treatment, directly heat distil...

Problems solved by technology

At present, most of the existing distillation equipment is conventional atmospheric pressure distillation equipment, such as Chinese invention patent 2011204817691 volatile oil extraction tank, the distillation tank can not be operated at normal temperature and pressure, high temperature and high pressure or low temperature and low pressure according to the characteristics of medicinal materials, which has a negative impact on the quality of some volatile oils certain impact, and the volatile oil yield is low; there is also a prominent defect that, due to the shape design and internal structure design of the tank, most of the existing tanks are cylindrical tanks with the same diameter up and down, so that the medicine passes through After a period of distillation, the material shrinks, and there is a side seam between the inner wall of the tank and the material, and the steam slips away along the side seam without resistance, and the material cannot be effectively distilled, such as the invention patent 2014205784788 multifunctional extraction tank , it is necessary to add the extraction solution to the tank through the top return pipe for circulation extraction, and the extraction efficiency is low
