Device of quickly extracting natural pigments from flowers of plants

Abstract

The invention relates to a device of quickly extracting natural pigments from flowers of plants. The device includes, in a successive manner, a first extraction apparatus, a second extraction apparatus, a first filter apparatus, a second filter apparatus, an extract liquid storage tank, a pressure reduced concentration apparatus, a spray drying apparatus, and a heat exchanger. A heat exchange tube is arranged in the extract liquid storage tank. The inlet of the heat exchange tube is connected to a gas outlet of the pressure reduced concentration apparatus. The outlet of the heat exchange tube is connected to a hot fluid inlet of the heat exchanger. A cold fluid inlet of the heat exchanger is connected to the outlet of an extraction agent storage tank and a filtrate outlet of the second filter apparatus. A hot fluid outlet and a cold fluid outlet of the heat exchanger are respectively connected to extraction agent inlets of the first extraction apparatus and the second extraction apparatus. By means of the technical scheme, heat energy in vapor in the pressure reduced concentration apparatus is recycled and utilized for preheating an extract liquid and an extraction agent, thereby achieving temperature maintenance and preheating of the extract liquid before pressure reduced distillation and heating of the extraction agent. The device saves energy and reduces production cost.

Description

[0001] The present invention is a divisional application for an invention patent with the application date of July 18, 2015, the application number 2015104270201, and the invention name "Equipment for Rapidly Extracting Natural Pigments from Plant Flowers". technical field [0002] The invention relates to the field of natural pigment extraction, in particular to a device for rapidly extracting natural pigments from plant flowers. 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 ...

AI Technical Summary

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

[0004] 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.
