Problems solved by technology

[0003] In the prior art, the methods used to produce the extract of Cistanche mainly include water extraction and alcohol precipitation method, that is, first use water as a solvent to extract the effective active ingredients in Cistanche, and then add high-concentration ethanol to the extract for shaking and static filtration to obtain Remove impurities to obtain Cistanche extract, which mainly contains phenylethanol glycoside compounds, but this method has large solvent consumption, long production cycle, high production cost, and high impurity content in Cistanche extract, etc. question
[0004] The Chinese patent literature discloses an invention patent titled "raw material containing phenylethanol glycosides produced from Cistanche deserticola using membrane separation technology" (document number CN101041677), which uses a combination of water extraction, alcohol precipitation and membrane separation Carry out the production and processing of Cistanche deserticola extract. The specific steps are: first collect the extract by water extraction and alcohol precipitation, then centrifugally filter the extract, filter the supernatant obtained by filtering through a ceramic membrane and an ultrafiltration membrane, and then pass the filtrate through a nano Membrane filtration, and finally the retentate of nanofiltration is dried to obtain Cistanche extract. The preparation of Cistanche extract by this method also has the problems of long production cycle and low product purity. Not only that, the equipment cost of centrifuge and ceramic membrane Relatively high, causing economic pressure on business investment

Abstract

The invention discloses a production system for a cistanche extractive. The extractive comprises a feed tank, a first security filter, an ultrafiltration unit, an adsorbing exchange resin pillar, a second security filter and a reverse osmosis unit which are arranged in sequence, wherein the input end of the first security filter is connected with the output end of the feed tank; the output end of the first security filter is connected with the input end of the ultrafiltration unit; the input end of the adsorbing exchange resin pillar is connected with the filtrate outlet of the ultrafiltration unit; the output end of the adsorbing exchange resin pillar is connected with the input end of the second security filter; the input end of the reverse osmosis unit is connected with the output end of the second security filter; the concentrate outlet of the reverse osmosis unit is connected with a spray drying device. Through the combination of the filtration of the ultrafiltration unit, the separation of the adsorbing exchange resin pillar and the concentration technique of the reverse osmosis unit, the purity of the product can be effectively improved, and the produced cistanche extractive can meet the food grade requirements.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a production system of Cistanche deserticola extract. Background technique [0002] Cistanche is a plant of the family Danaceae, which has multiple functions such as tonifying the kidney and strengthening yang, anti-aging, enhancing memory, and improving immunity. Since the 1980s, a lot of research has been done on the chemical components of Cistanche at home and abroad. With the rapid development of detection technology, researchers have successfully isolated and extracted a variety of active substances from Cistanche deserticola, among which phenylethanol glycosides are the main active ingredients in Cistanche deserticola. [0003] In the prior art, the methods used to produce the extract of Cistanche mainly include water extraction and alcohol precipitation method, that is, first use water as a solvent to extract the effective active ingredients in Cistanche, and ...
