Technical field
The invention belongs to a kind of process for extracting tea polyphenol, more particularly to a kind of Tea Polyphenols extraction equipment.
Background technology
Although there is a variety of extraction towers on present society, the extraction of Tea Polyphenols is all impractical in, because different products
The extraction tower of different structure is needed with different process routes.Tea Polyphenols needs to add ethyl acetate as extract when producing,
As the boiling point of ethyl acetate is relatively low, volatile after heating, with Tea Polyphenols good separating effect.But as ethyl acetate is to people's
Eye, N＆T have stimulation, and belong to inflammable explosive article, need to recycle which in closed environment, a side
Face recycling is cost-effective, on the other hand can reduce its harm.Conventional retracting device is to adopt cold-trap, in prior art
Cold-trap organic efficiency low, be not suitable for ethyl acetate trapping reclaim.And due to using the tealeaves that crushes when Tea Polyphenols is produced
Used as being entrained with more impurity in raw material, its gas for volatilizing, cold-trap of the prior art is very difficult to the removal of impurity, affects back
Ethyl acetate after receipts.

Through hole, is provided with screen pack below distributing disc, the tank wall above the screen pack is provided with slag notch.
Further, turbulent flow barrier plate is provided with the uppermost one piece of sieve plate upper surface of described piece of sieve plate.
Further, lower turbulent flow barrier plate is provided with nethermost one piece of sieve plate lower surface.
Further, middle turbulent flow barrier plate is provided with by extracting tower shell between each piece of block sieve plate.
Beneficial effects of the present invention：Using this extraction equipment, the extractant as extraction phase is from extractant import under tower
Portion passes into sieve plates at different levels and goes out from tower top, passes at different levels sieve plates from stoste outflow from tower top as liquid is extracted
Discharge from bottom, two-phase counter-current extraction is caused, be conducive to improving extraction rate.The lower turbulent flow barrier plate of upper, neutralization, can make turbulent flow
Liquid is static as early as possible to get off, so as to accelerate layering.Spacing between the size of sieve aperture and sieve aperture can control the flow of turbulent flow and flow velocity.
