Energy saving apparatus for extracting plant flavones

Abstract

The invention relates to an energy saving apparatus for extracting plant flavones. The apparatus comprises an extraction device, a filtering device, an extract liquid storage tank, a resin bed, an eluate storage tank, a reduced pressure concentration device and a freeze drying device which are sequentially arranged, a heat exchanger is arranged between the reduced pressure concentration device and the extraction device, a heat exchange tube is arranged in the eluate storage tank, the inlet of the heat exchange tube is connected with the concentrate outlet of the reduced pressure concentration device, the outlet of the heat exchange tube is connected with the freeze drying device, the fluid inlet of the heat exchanger is connected with the gas outlet of the reduced pressure concentration device, the fluid inlet of the heat exchanger is connected with the outlet of an extracting agent storage tank, and the cold fluid outlet and the hot fluid outlet of the heat exchanger are connected with the extracting agent inlet of the extraction device. In the above technical scheme, heat energy of steam in the reduced pressure concentration device is recycled to preheat an extract liquid and an extracting agent in order to realize heat insulation / preheating before reduced pressure distillation of the extract liquid and heating of the extracting agent, so the energy is saved, and the production cost is reduced.

Description

[0001] This invention is a divisional application of an invention patent with the application date of July 18, 2015, the application number 201510426871.4, and the invention title of "Energy-saving Plant Flavonoid Extraction Equipment". technical field [0002] The invention relates to the field of extraction of natural flavonoids, in particular to an energy-saving equipment for extraction of plant flavonoids. 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 compon...

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.
