Drying equipment is widely used in many industries pharmaceutical and chemical. At the same time, with the industrial production technology and consumer requirements continue to increase, but also for drying equipment a higher technical requirements. Drying equipment used in the petrochemical business in the very common for the petrochemical business services, therefore, affected by relatively large sectors of the economy. This year, the petrochemical industry is not optimistic about the overall economic performance of the drying equipment industry is a challenge. Really be hit are small businesses, large enterprises are not affected significantly, some large companies but profit margins shrink some, output did not decline. For example, microwave vacuum dryer microwave energy technology and vacuum technology combined with a new type of microwave energy applications, it combines the microwave and vacuum drying series of advantages, to overcome the long conventional vacuum drying cycle, low efficiency shortcomings in Usually the material drying process than conventional methods to improve efficiency 4-10 times. Having a dry high yield, good quality, low processing costs, microwave vacuum drying equipment is a set of electronics, vacuum science, multidisciplinary mechanics, thermodynamics, science and other program-controlled high-tech products, it is in the drying process in-depth study on the basis of physical change material, internal and external heat and mass transfer and moisture migration process under vacuum conditions, the developed a new technology and new technology. Scientific and technological content of drying equipment previews the leading role. Since 2004, the situation continues to improve by the national chemical industry, driven by steady bullish drying equipment market situation, production companies generally get a better operating results. Currently serving the chemical industry drying equipment notable feature is the increasingly prominent role of technical content. This is the last sale of products by price competition has been very different. Among them, some of the drying equipment with high technical content, focusing on the development of new manufacturers, benefit steadily growing; on the contrary, a number of low-tech products, new products and new technology development capacity is weak companies, benefits began to decline. After more than ten years of development, at present, China's drying equipment industry has begun to enter a more mature phase, can better meet the actual needs of users in various fields, in view of the vacuum drying equipment, "green" advantages, widely used. In the food, pharmaceutical drier side, vacuum drying equipment demand for larger size will gradually increase, market prospects are very large. Experts say, to explore a new development path when drying technology, the need for energy efficiency, environmental protection and product quality into account, in order to achieve comprehensive, coordinated and sustainable development. To implement efficient and green dry development strategy, first go the path of development resources-saving, variable drying single extensive portfolio, intelligent dry. Not only from the drying process of fundamental transformation, but also to conduct a comprehensive, multi-level energy-saving technological transformation, to develop application of renewable energy and industrial waste heat drying technology. Compared with the current conventional oven drying method, spray drying method, continuous vacuum drying method has many unique advantages, to ensure product quality is much higher than other methods of drying products. Continuous vacuum drying equipment and technology because of low-temperature drying, the active ingredient less damage, loose and easy to absorb melting, drying and sterilization at the same time benefits, which can ensure the active ingredient is high, sterile indicators of high oral absorption. Insiders pointed out that domestic enterprises have accelerated research vacuum drying technology, some companies have made a breakthrough, reducing energy consumption to some extent, reduce pollution, the community has brought more benefits and value. Although some gaps in the current domestic production of drying equipment compared with developed countries still exist, but is gradually establishing advantage of domestic equipment, the basic realization of the domestic market leader. Vacuum drying equipment will become the mainstream market demand, the domestic industry must significantly enhance the technical level and increase drying efficiency, reduce energy consumption, to achieve green production to contribute their efforts.
