The effect of amino acid extraction using centrifugal extraction machine is introduced
amino acid is a kind of carboxylic acid on the carbon atoms of hydrogen atoms are replaced by amino compounds, its molecules contain amino and carboxyl functional groups, is a kind of amphoteric molecules. In the study of technology of the separation of amino acids, there are several kinds of separation methods, such as precipitation, ion exchange, membrane separation, extraction, etc. Each have advantages and disadvantages of these methods, such as precipitation is easy to operate, but the precipitant easy recycling residue, difficult; Ion exchange method, the operation is simple, but the separation process produces a large amount of wastewater effluent; Membrane separation operation condition is good, but easy to be polluted and blocked membrane; Compared with the previous methods, the advantages of solvent extraction is more outstanding, extraction solvent can be recycled, less waste liquid separation process of wastewater treatment.
zhengzhou days extraction by using solvent extraction separation of amino acids are extracted, and found that the effect is very good, high extraction rate, the solvent can be recycled and reused. The selection of extraction agent in the solvent extraction method is particularly important for the extraction of amino acid, common several extractants are: 1, organophosphorus extractants, 2, 3 organic amine extraction agent, crown ether extraction agent and calixarene type.
in view of the different solvent, in the process of extraction, need according to certain proportion of the raw material and solvent injection centrifugal extraction machine. With the aid of the rotation of the drum, through the turbine disc and the impeller to make two phase mixing and dispersing quickly, two phase solution fully mass transfer, mixing and mass transfer process. Mixture under the action of vortex disk into the rotary drum, in under the action of centrifugal force, complete separation, clarification of two phase fluid end respectively through their weir plate into the collection chamber and the tube was closed to derivation, respectively, to complete the two phase separation process. Extract the organic load of phase need to adopt the back extraction solvent extraction agent, recycling use again.
days. cwl - extraction research and development production M series centrifugal extraction machine the advantages of separation of amino acids in the extracting features:
1, simple structure, stable - — Using suspension single fulcrum structure, processing area at the bottom of the bearing and mechanical seal, no leakage risk, solved the centrifugal extraction machine failure frequently, the problem of short service life, save the costs for equipment maintenance.
2, energy saving, — Capacity bigger, more energy saving, Under the condition of same capacity, its power consumption is a traditional annular structure of centrifugal extraction machine 1/10 ~ 1/3) 。
3, corrosion resistance, — Equipment is available in using perfluorinated polymer materials, resistant to strong acid, Hydrochloric acid and mixed acid, etc. ) The corrosion.
4, mixing, separation effect is good, — A variety of hybrid structure is optional, high separation efficiency, can be applied to easily emulsifying system.
5, heavy phase weir plate easy to change - — Material system changes, the heavy phase weir plate can realize quick change, the operation is simple and convenient.
6, equipment to save small amount of liquid - — The effective volume of equipment.
7, a high degree of automation, — Can realize online real-time monitoring equipment operation data, can be selected in accordance with GMP standard online cleaning system, fully able to adapt to the intermittent and continuous operation.
