Process, no phase transformation, energy consumption is low, and system operates at normal temperatures, overcomes destruction of the heat to active material in enzyme preparation product.
A kind of inexpensive epiphysin separation method, comprises the following steps：
Step 1: pretreatment：Obtained walnut is subjected to liquid nitrogen frozen processing；
Step 2: crush：Crushed after walnut after freezing is added into leaching agent；
Step 3: leach：Walnut after crushing is extracted to the required composition leached in walnut repeatedly, obtains leachate；
Step 4: film process：Obtained leachate is handled by film, removes the salinity and small-molecule substance of centre；
Step 5: decolorization：Leachate after film process is subjected to decolorization, is put into resin column, carries out decolorization；
Step 6: revolving：Leachate after decolorization is put into Rotary Evaporators and carries out revolving processing, by leaching therein
Agent evaporates, and can be continuing with；
Step 7: dry：Obtained epiphysin is put into drying box and is dried, removes the leaching agent not eliminated.
The step 2, the walnut after freezing is crushed by wet pulverizing.
The step 3, leaching agent is used as by petroleum ether, the walnut after crushing is carried out to be put into ultrasonic unit progress
Leaching process, when being delivered to by ultrasonic vibration in liquid, cavitation effect is excited, so as to produce substantial amounts of cavitation gas in a liquid
Bubble, with the generation of these cavitation bubbles and explosion, microjet will be produced, enter to be about to the great solid particle of liquid and smash, simultaneously
Due to the vibration of ultrasonic wave, solid-liquid is more fully mixed, make clasmatosis, the extraction of cell inclusion is more perfectly sound.
The step 4, concentrating and separating processing is carried out by reverse osmosis membrane, use cotton, timber of containing cellulose etc. as original
Material, acetic acid, Triafol T are made through over-churning and hydrolysis（CA、CTA）, it is reprocessed into reverse osmosis membrane.
The step 5, handled by the ion exchange resin in resin column, ion exchange resin with styrene and
Divinylbenzene is the cross-linking products of skeleton, is porous spongy along with corresponding function group such as sulfonic group or quaternary ammonium
The skeleton of construction, there are a large amount of permanent micropores inside, then imports cation exchange groups and be made, and has micropore and big mesh, soaks
The aperture of resin is up to 100~500nm.
The step 7, processing is dried by vacuum drier.
The inexpensive epiphysin separation method of the present invention has the following advantages that：
The inexpensive epiphysin separation method includes, pre-processed, crushing, leaching, film process, decolorization, revolving, drying.
Solve in the prior art, it is difficult to use biochemical treatment that a large amount of resins, which elute poisonous waste water, brings heavy economy to bear to enterprise
Load and environmental protection pressure.The inexpensive epiphysin separation method of the present invention is pure physical process by film process process, no phase transformation,
Energy consumption is low, and system operates at normal temperatures, overcomes destruction of the heat to active material in enzyme preparation product.Reduce active ingredient damage
Lose, reduce BOD and COD contents in waste water.Compared with traditional filtering, concentration technology method, new technology can significantly save technique
During inorganic salts, organic solvent, reduce the production cost of product.
