Two-stage digestion equipment applied to extraction of rhododendron simsii active components

Abstract

The invention relates to two-stage digestion equipment applied to extraction of rhododendron simsii active components. The two-stage digestion equipment comprises a first digestion device, a second digestion device, a first filtering device and a second filtering device, wherein the first digestion device and the second digestion device are used for extracting rhododendron simsii in sequence; the first filtering device and the second filtering device are used for respectively performing solid-liquid separation on materials obtained after extraction inside the first digestion device and the second digestion device; the liquid outlet in the first filtering device is communicated with an extract storage tank; the liquid outlet in the second filtering device is communicated with the extraction agent inlet in the first digestion device. According to the scheme, leaves / flowers of rhododendron simsii are respectively extracted inside the first digestion device and the second digestion device, as the extract obtained after the leaves / flowers of rhododendron simsii are extracted for a second time is relatively low in concentration of pigment / flavones, the filtrate obtained after filtration separation is taken as the extraction agent for extraction of a first time, then the contraction of pigment / flavones in the extract can be increased, convenience can be brought to later distillation concentration treatment, and meanwhile, due to two-stage extraction, the extraction period can be effectively shortened, the energy can be saved, and the production rate of pigment / flavones can be increased.

Description

[0001] This invention is a divisional application of the invention patent with the application date of July 18, 2015, the application number: 201510428917.6, and the invention name "Yingshanhong secondary extraction equipment". technical field [0002] The invention relates to the field of extraction of active components, in particular to a secondary extraction equipment applied to the extraction of active components of azalea. Background technique [0003] In the field of extraction of natural active components, it is often necessary to use an extraction device to extract the roots, stems, and leaves of natural plants, so that the active ingredients in the roots, stems, and leaves of herbal plants are dissolved in the extractant, so as to realize the extraction of active ingredients. extraction. Most of the existing extraction tanks have the problems of cumbersome and time-consuming feeding and unloading of materials, which seriously affects the production efficiency of nat...

Problems solved by technology

Most of the existing extraction tanks have the problems of cumbersome feeding and unloading of materials and time-consuming problems, which seriously affect the production efficiency of natural active components

In addition, for the extraction of natural active components, there is an optimal material ratio (the extraction rate and / or extraction efficiency of the active components under this material is the largest), but it is difficult to accurately control the material ratio in the feeding of traditional extraction tanks, making the extraction The yield and / or extraction efficiency cannot be optimized, seriously affecting production efficiency and causing waste of raw materials
