System for rapidly extracting pigments from rhododendron simsii planch flowers

Abstract

The invention relates to a system for rapidly extracting pigments from rhododendron simsii planch flowers. The system comprises a first extraction device, a second extraction device, a first filter device, a second filter device, an extracting solution storage tank, a decompressing concentration device, a freeze drying device and a heat exchanger which are sequentially arranged, wherein a heat exchange pipe is arranged in the extracting solution storage tank; an inlet of the heat exchange pipe is connected with a concentrated solution outlet of the decompressing concentration device; an outlet of the heat exchange pipe is connected with the freeze drying device; a thermal fluid inlet of the heat exchanger is connected with a gas outlet of the decompressing concentration device; a cold fluid inlet of the heat exchanger is connected with an outlet of an extracting agent storage tank and a filtrate outlet of the second filter device; a cold fluid outlet and a thermal fluid outlet of the heat exchanger are connected with extracting agent inlets of the first extraction device and the second extraction device. According to the technical scheme, thermal energy of steam in the decompressing concentration device is recycled, an extracting solution and an extracting agent are preheated, thermal preservation / preheating of the extracting solution before decompressing distillation as well as extracting agent heating are realized, so that the energy is saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of natural pigment extraction, in particular to a system for rapidly extracting pigment from azalea. Background technique [0002] 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 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 contr...

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

[0003] In addition, the currently used active component extraction equipment generally has problems such as low extraction rate, low energy utilization rate, and long extraction cycle.
