Tea polyphenols production equipment preferred shenzhen long source
water treatment specializing in the production of tea polyphenols
extraction equipment ， the first-class technology, equipment,
stable performance, perfect after-sale service and equipment
installation experience, is your first choice!
Tea polyphenols (tea polyphenols) is not only a new natural
antioxidant, its antioxidant activity is higher than general non
phenol or single phenol by the base class antioxidant, but also has
to fat to reduce weight, reduce blood sugar, blood fat and
cholesterol, prevent cardiovascular disease, inhibiting tumor cell
and pharmacological function, in food processing, medicine, daily
chemical and other fields have a wide range of application. In
recent years, through the use of low-grade tea or tea processing
scraps extraction production high value-added fine fine chemicals -
tea polyphenols, more and more attracted people's attention.
The traditional tea polyphenols extraction technology are: solvent
extraction, ion precipitation and column separation preparation
method. Solvent extraction method is to use polar solvent from tea
leaching, and then put the leaching liquid to liquid liquid
extraction and separation, and finally get the goods enrichment.
The method USES a variety of organic solvents, the production cost
is high, some poisonous substances in the organic solvent products
and operations are safe, and easy to cause environmental pollution,
solvent extraction method is not suitable for industrial
production. Ion precipitation is the use of heavy metals to
precipitation of tea polyphenols, caffeine and with the separation,
such as copper salt, lead salt or aluminium trichloride. The method
USES the human toxic heavy metal as precipitation, and its products
for food and pharmaceutical industry cannot be accepted.
Has been reported column separation preparation method have gel
column, adsorption column and ion exchange column. The column
separation equipment method tea polyphenol yield between 4% and 8%,
the purity can reach *8.1%, if use gel column separation can be
highly to take off the caffeine, its residual amount is only 0.1%.
But column filling material such as adsorption type resin, close
fat gel and very expensive, separation easy pollution caused by
congestion, washed out when using a variety of, a lot of organic
solvent, the single column chromatography to industrial im tea
polyphenol is not appropriate.
With the development of membrane separation technology, membrane
separation technology in combination with low temperature
extraction and separation technology can avoid the active
ingredients of oxidation loss and improve the yield.
Ultrafiltration membrane purification refining extract,
nanofiltration and reverse osmosis membrane cryogenic concentration
refined liquid, can prolong resin use cycle and reduce the elution
agent usage, improve the adsorption efficiency, and to facilitate
the recovery of tea polysaccharide. If use secondary resin
adsorption and chromatography separation, but also can get
by-product caffeine, before and after the process of organic whole,
can produce three products, raw material utilization ratio is high,
the attached value greatly improved.
Long source company give full play to their advantages of membrane
separation technology, membrane technology developed integrated
extraction, column chromatography technology of tea polyphenols
extraction optimization of process, make the process become simple,
easy to control, and yield increase, the product quality is stable
and reliable.
Membrane extraction of tea polyphenols technology advantages:
· a high degree of automation, simple operation, easy to clean
· membrane element imported components, long service life, no
change often
· separation effect is good, concentrated uniform, low energy
consumption and high efficiency, operation cost is low (is the
traditional process of 1/**1/5)
· extraction solvent consumption significantly reduced, the product
quality improved obviously, greatly reduced the loss of active
ingredients
· to enhance product purity and quality, the product yield has also
greatly improved
· low temperature membrane method processing, the production of the
product color, fragrance, taste with better
· in extracting tea polyphenols, still can extract tea
polysaccharides and caffeine, improve the utilization rate and
economic benefit
· membrane process no pollutant discharge, reduce the waste water
discharge pressure, reduce the waste water treatment of
investment
