Homogeneous emulsifiers have become increasingly important in contemporary life and have penetrated into many fields. For example, auxiliaries used in the textile industry must be homogeneously emulsified before use to increase the efficiency of the auxiliaries. Another example is the fuel additive is a new breakthrough in the homogeneous fuel emulsification technology in the fuel industry, can be widely used in the automotive industry and other places where fuel is needed to improve the combustion process and improve thermal efficiency, so the study of homogeneous fuel emulsification is promising.
From an example of the most commonly used homogeneous technology application, homogenization in condensed milk, we can understand the role, mechanism and efficacy of homogenization. When condensed milk (non-sugar condensed milk) is left for a long period of time, the creamy layer of the upper layer is prone to occur, and creamy particles may be formed due to vibration, which greatly reduces the commercial value thereof. Homogeneous emulsification machine homogenizing treatment, can make the fat globules smaller, increase its surface area, thereby increasing the adsorption capacity of the protein on the surface of the fat globules, increasing its specific gravity, decreasing the floating capacity, and at the same time reducing the surface tension of the fat globules. Its tendency to regroup has weakened. In addition, homogenization can also improve the digestion and absorption properties of dairy products.
The research on homogenized emulsification technology at home and abroad has a long history and many advances have been made. Since the 30th century, foreign countries have begun to develop homogenous emulsifiers. At present, more than 10 countries, including the United States, Japan, Italy, the Netherlands, Germany, and Denmark, have produced homogenizers with considerable production volumes and varieties, and many patents have been issued at the same time. The products, of which the former Soviet Union had the most patents, were 45 in 1985 and accounted for half of the 90 homogenous machine patents worldwide. In recent years, the development of homogeneous emulsifiers has been continuously combined with new technologies.
Due to the popularization and use of high-pressure homogenizing equipment in nutrient solutions, bio-engineering, ultra-micro-crushing and nano-technology, its product coverage has rapidly expanded, and the pressure required to use it has also increased. Recently, from Shanghai East China Homogenous Machinery Factory understands that more and more customers are required to use pressures above 100MPa. However, there are not many domestic factories that can produce pressures of 100 MPa, while only 150 MPa homogenizers can produce only some leading enterprises. The equipment abroad is relatively mature, and the maximum pressure can reach 200 MPa, but it is difficult for domestic users to accept because of its high price and difficulty in providing wearing parts.
With the need for automated production of modern large-scale industries, homogenizers can be independently connected in series. Greatly improved the degree of automation of food production. In order to make the food production line can be continuously stable, hygienic and efficient work, it needs a good match between the homogenizer and the pre-processing equipment, and can automatically adjust the technical parameters remotely under the dynamic conditions, and automatically check the operation status of each department. Automatically identify faults and automatically shut down under special conditions.
In general, the overall level of China's homogenizer is behind that of developed countries by many years. In addition to the improvement in the technical level of domestic manufacturers, the localized production of foreign companies also greatly promotes the improvement of the level of homogenizer automation in China.
