The
. cwl - M type centrifugal extraction machine because of its small stock of two phase materials in the equipment, contact time is short, 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 great capacity, hence. cwl - M type centrifugal extraction of traditional Chinese medicine (TCM) garlic oil extraction machine has high reingistic. This article mainly from the overview of the characteristics of garlic oil, traditional Chinese medicine (TCM), as well as. cwl - performance M type centrifugal separation principle of extraction machine, the use. cwl - is determined M type centrifugal extraction machine extraction process conditions of garlic oil.
steam distillation extraction of garlic oil
the principle is to water vapor flux into insoluble or poorly soluble in water but have certain volatile organic matter ( Garlic oil has a certain volatile) , so that the organic matter under the temperature below 100 ℃ with steam distillation, then through further separated to obtain relatively pure substance. The provisions of the general process for: garlic peeling to wash, add water mash to enzyme solution to water vapour distillation, oil-water separation, garlic oil.
water vapor distillation method has simple equipment, low cost, good stability, etc. , is one of the most commonly used method. But because of relatively high temperature fermentation and distillation, garlic neuraminidase activity decline, garlic, known as loss, make the yield efficiency is low. And the garlic oil had a familiar smell, not fresh enough.

solvent extraction to extract garlic oil, garlic oil, slightly soluble in water, soluble in ethanol, benzene, ether and other organic solvent, can take advantage of this nature garlic oil with organic solvent extraction. Solvent extraction method to extract garlic oil equipment for. cwl - elected M type centrifugal extraction machine, solvent extraction method of extraction of garlic oil with steam extraction of garlic oil had no obvious difference. The choice of the organic solvent is the key to the good solvent solubility of garlic oil, leaching after the easy separation, significant difference was found in the boiling point, excluding other bad smell and solvent residue. Solvent method, the general process for: garlic peeling - wash - pounded to digestion, the solvent extraction - distillation separation - recovered solvents and garlic oil.
CWL - 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. 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. 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. Refs
