Sage acid is rosemary rosemary plants belong to the inside of a component. Carnosic acid has wide application and can be used for grease and fat food, biological medicine, chemical industry, cosmetics and feed and so on, besides can prevent or delay the oxidation of oil or oily food, to enhance the stability of food and extend the storage time of storage, and as a seasoning meat and fish, it also has good physiological and pharmacological activities.
days use. cwl - extraction M type centrifugal extraction method of organic solvent purification carnosic acid process: the rosemary smoked bean curd leaf broken into. cwl - in an ethanol M type centrifugal extraction machine reverse extraction in the extraction, separation of carnosic acid are obtained. . cwl - M type centrifugal extraction machine by solvent extraction principle
some of which were extracted from liquid mixture operation known as liquid/liquid extraction. Centrifugal extraction machine extraction is the use of components selected in the solution of the differences in the solubility of solvent, the solute of liquid-liquid mass transfer, in order to achieve the separation of homogeneous liquid mixture operation. Centrifugal extraction machine extraction operation process can include:
1. Raw material liquid mixed with the extracting agent fully contact, complete the solute mass transfer process;
weight according to certain proportion respectively from two two phase solution and feeding tube into the drum shell ring gap formed between the mixed zone, 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. Complete mixing and mass transfer process.
2。 Extraction and extraction residual phase separation process;
mixture under the action of vortex disk into the rotary drum, in the plate to form the bulkhead area, mixture quickly with synchronous rotary drum, in under the action of centrifugal force, the heavier than major phase fluid in the process of upward mobility and gradually away from the drum center on the drum wall; Small proportion of liquid phase gradually away from the drum wall and on to the center, after 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 two phase separation process.
3。 From the extraction phase and extraction phase extractant recycling process.
usually use the method of distillation recycling extracting agent. Removal after extraction of proportion as the extractant extract; After removal from the extraction agent over extraction of proportion of extraction liquid.
2. CWL - The characteristics of M type centrifugal extraction machine:
(1) to adapt to the strong performance - — Compared with the traditional van and extraction tower equipment, under the effect of centrifugal force, the remaining time is short, split phase quickly, to adapt to the wide range of flow ratio, and processing power; By changing the weir plate and frequency control of motor speed can meet the different density and viscosity of liquid materials;
2 material stock of small - — Two-phase material stock in the equipment is small, short contact time, more suitable for processing because of long time volatile activity and variability of materials such as antibiotics, etc. , of course, individual system needs two phase together contact time long also can operate separately.
(3) high extraction efficiency - — Phase equilibrium set up fast, easy to implement series single stage or multistage counter-current or wrong washing and extraction, high mass transfer efficiency and grade efficiency approaching 100%, stop not to undermine the established after concentration distribution at different levels, can at any time at all levels of sampling, facilitate testing.
(4) to take up the space is little, — Motor direct drive, no transmission attachments, compact structure, save area and operating space, less auxiliary equipment.
5] adaptable - — Not because of the change of the material influence extraction effect, can deal with small difference in density between the viscosity of the system, and has a strong ability of demulsification.
[6] operating performance is good, — Automatic operation, the operation flow ratio range is very wide. Can continuous uninterrupted operation, also can use small batch more varieties; Can be intermittent operation, can be a single run, also may need many sets of series operation according to the craft, unlimited number, installation, operation and maintenance is simple, you need less workers, can significantly reduce the labor intensity of workers and improve working environment, and a parking is convenient, easy to implement online analysis and automatic control, etc. Power can be run. Without the traditional process of high tower transporting fluid.
once continuous counter-current reliability - — Current implementation is imposed by the mixing chamber of the suction force per level, does not need the other set interstage pump. No force during conventional process equipment capacity, prone to flooding, multistage series connection must be set when the interstage pump.
being supplied equipment easy to enlarge - — Practices prove that small equipment in lab scale and mass production with large equipment effect is exactly the same, unnecessary to consider the amplification effect.
'levies investment costs low - — Content of small machine, extraction solvent, solvent or detergent consumption minimum
⑽ sealed performance is good, — Meet the explosion-proof, and the application of the poisonous and harmful and volatile medium environment and the requirements of GMP.
