In the field of food, medicine, chemical and other fields of laboratory research, separation, purification, extraction is an essential part of the experimental process.In order to meet the needs of various industries and research applications to make up for the shortcomings of the traditional separation techniques, a new The separation technology was born, that is, the molecular distillation technology.The emergence of this technology for the separation of needs in various fields provides a new technology, a separation of a technology field star.
Molecular distillation, also known as short-range distillation, is a liquid-liquid separation technique developed with the development of vacuum technology and vacuum distillation technology.After a long period of development, the technology is rapidly changing, which well eliminates the defects of traditional distillation At present, as a high - tech liquid separation technology under high vacuum conditions, it has a wide range of applications in the separation and purification of petroleum processing, cosmetics, foodstuffs, pharmaceuticals, etc. China National Chemical instrument Network summarizes the molecular distillation equipment in the following areas of development and application.
Application of Molecular Distillation Apparatus in Sample Preparation
In recent years, due to high-precision analysis and testing equipment Development and testing techniques are increasing, and sample preparation techniques are gaining more and more attention, especially for the selective extraction of certain target compounds during the chromatographic analysis. The molecular distillation technique can be used to measure trace amounts of target compounds For extraction and separation and enrichment, the application of great potential.Especially in the analysis and testing of trace organic pollutants, a variety of organic phosphorus and carbamate, organic chlorine, pesticides and preservatives and other harmful substances Liquid samples are pretreated.
Application of Molecular Distillation Apparatus in the Field of Traditional Chinese Medicine
In recent years, the rapid development of molecular distillation technology has gradually become one of the key technologies for the separation and purification of the active ingredients of traditional Chinese medicine.According to the verification, the technology has the advantages of low distillation temperature, low system pressure, short heating time, high degree of separation, It can be used in the separation and enrichment of volatile oil and other active ingredients from the extract materials. It can be used in the separation and removal of fatty acid from fatty oil to significantly reduce the acid value. It can be used in the separation and enrichment of effective volatile Sexual ingredients and so on.
Application of Molecular Distillation Apparatus in Honey Concentration
Honey concentrates play an important role in the processing and production of honey products.At present, there are some quick-check methods for honey and propolis, such as the rapid test kit for honey moisture and the quick check kit for honey and sucrose, but most of these products are only qualitative or Semi-quantitative detection. Molecular distillation technology to overcome the high temperature conventional distillation, heating a long time and other shortcomings, as well as impure, a large number of solvent residues, impurities and other problems not clear net, can effectively improve the efficiency of honey enrichment and reduce costs, to achieve the most Good concentration effect, which has a wider range of applications in the processing and application of bee products.
All in all, as a popular international high-tech liquid-liquid separation technology, compared with the traditional vacuum distillation technology, it successfully overcomes many problems and shows the advantages of simple process, less time consumption and energy saving, and has the advantages of Great development prospects.While our country molecular distillation technology, our country in the field of research and application started relatively late, but also need to further upgrade technology and improve equipment, expand its application in all walks of life, to achieve industrial production.
