Dendrobium extraction device

Abstract

The invention provides a dendrobium extraction device, belongs to the technical field of extraction of natural plants and aims to solve the technical problems of low extraction efficiency and low content of effective components in the prior art. The dendrobium extraction device comprises an extraction tank, wherein the extraction tank comprises a tank body; a jacket connected with the tank body in a sealing manner is arranged at the exterior of the tank body; at least one discharging hole communicated with the jacket is arranged on the inner wall close to the top of the tank body; at least one overflowing hole is formed in the outer wall close to the top of the jacket; a cylindrical isolation barrel is arranged at the interior of the jacket; the top of the isolation barrel is connected with the top of the jacket in a sealing manner; a gap is formed between the bottom of the isolation barrel and the bottom of the jacket; the isolation barrel is used for dividing the inside of the jacket into a first discharging area and a second discharging area; the discharging holes are communicated with the first discharging area; the overflowing holes are communicated with the second discharging area. The dendrobium extraction device is high in extraction efficiency and is capable of effectively implementing solid-liquid separation, improving the content of the effective components and implementing continuous operation.

Description

technical field [0001] The invention belongs to the technical field of natural plant extraction, and relates to a dendrobium extracting device, which is suitable for extracting effective components of the dendrobium. Background technique [0002] As a kind of yin-nourishing medicine, Dendrobium is mostly used for symptoms such as yin deficiency and fever, body fluid injury, polydipsia, dark eyes and dim flowers. Since it was first recorded in "Shen Nong's Materia Medica", after more than two thousand years of development, there have been dozens of plant sources involved in Dendrobium, and according to the "Pharmacopia" (2005 edition), there are mainly three sources: Dendrobium nobile, Dendrobium candidum, Dendrobium versicolor. Dendrobium candidum is the top grade of Dendrobium, with the best ability to nourish yin and remove heat, and is an ideal raw material for developing health care products. The active ingredients in Dendrobium mainly include active polysaccharides, d...

Problems solved by technology

Since the fresh Dendrobium is in the form of strips, but the processed Dendrobium is in the form of curly large particles, if the direct extraction effect is very poor, it is necessary to grind or cut the processed dried Dendrobium for extraction, so as to increase the extraction rate of active ingredients , but also encountered a problem at the same time, although the crushed Dendrobium can increase the extraction rate, it is difficult to effectively separate the Dendrobium powdery slag from the extract, which affects the extraction speed and efficiency, and also reduces the content of active ingredients
