Device for extracting azalea

Abstract

The invention relates to a device for rapidly extracting an azalea pigment. The device comprises a first extraction device, a second extraction device, a first filtering device, a second filtering device, an extracting solution storage tank, a decompression and concentration device, a spraying and drying device and a heat exchanger, which are arranged in sequence, wherein the extracting solution storage tank is internally provided with a heat exchange pipe; an inlet of the heat exchange pipe is connected with a gas outlet of the decompression and concentration device; an outlet of the heat exchange pipe is connected with a hot fluid inlet of the heat exchanger; a cold fluid inlet of the heat exchanger is connected with the outlet of an extracting agent storage tank and a filtrate outlet of the second filtering device; a cold fluid outlet and a hot 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, heat energy of steam in the decompression and concentration device is recycled and is used for pre-heating an extracting solution and an extracting agent, and the preservation / pre-heating before the extracting solution is decompressed and distilled is realized and the extracting agent is heated, so that energy sources are saved and the production cost is reduced.

Description

[0001] This invention is a divisional application of the invention patent with the application date of July 18, 2015, the application number of 2015104270273, and the invention title of "Azalea Extraction Device". technical field [0002] The invention relates to the field of natural pigment extraction, in particular to a device for extracting 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 natural active components. In addition, for the extraction of natural active com...

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
