It is estimated that China's drying equipment manufacturers are about more than 500, with annual sales of more than 3 billion yuan. In terms of quantity, is the largest country in the world production of drying equipment considered. However, the majority of our production level enterprise technical drying equipment is not high, and some do not even have technology at all. In China, the application of drying equipment has been for decades. The past 20 years, the rapid development of drying equipment industry, through the efforts of the engineers and technicians, the most industrialized country models can be manufactured, basically reversing the drying equipment to rely on imports of the situation, but also the emergence of a large number of drying equipment manufacturing enterprises. It is estimated that China's drying equipment manufacturers are about more than 500, with annual sales of more than 3 billion yuan. In terms of quantity, is the largest country in the world production of drying equipment considered. However, the majority of our production level enterprise technical drying equipment is not high, and some do not even have technology at all. A number of low investment, low-tech "motley crew" with a lot of low-quality, low-cost devices crowding the market, not only affects the overall image of drying equipment, drying equipment more attracted domestic price of "infighting", making China the overall competitiveness of the drying equipment is difficult to get to play. Restricting the development of China's R & D deficiency in automation and control the degree of drying equipment, appearance quality, feature sets and combinations of terms vary considerably with foreign advanced level, the main problem is not the performance of technological innovation capability and strong regional focus in two ways. Lack of theoretical research is constraining the development of drying equipment is a major bottleneck. Physical properties of dry material is varied, several drying equipment alone can not meet the needs of production. Theoretical research is the basis for the development of new dryers, drying technology development in China, is necessary to train a group theoretical research, development workers drying technology to improve the technical content of the drying equipment. In recent years, although there are some universities or research institutes are doing work in this area, but the input of manpower, material enough. In our theoretical research there is still a gap compared with Denmark, Canada, Japan and other countries. Meanwhile, the drying equipment companies still lack a qualified laboratory processes. So far, both drying plant or theoretical research units, are not a perfect experimental base. Drying is a highly experimental technology, whether theoretical research or drying equipment manufacturing, experimental methods are essential. Through experiments, theorists can conclude that many of the laws of the drying process, equipment manufacturers through a variety of experiments to determine the process parameters. However, many units just ignore the importance of the experiment. Some do not even have an experimental plant equipment, there are a lot of blindness in device design. Currently, there are experimental means weak in these areas, lack of one equipment manufacturer to experiment understanding that dispensable. Second, the experimental device models are more huge investment, non-general business can afford. Built a sound base is a priority of the experimental study of drying technology. Third, the lack of laboratory personnel, the experimental results of the analysis capability is weak. Some companies do not have a technical staff, equipment, production process without even drawing alone machining staff estimates and experience to produce worth hundreds of thousands, hundreds of million of equipment, this phenomenon is not uncommon in the drying equipment industry . While restricting the development of the industry is another reason, though China has a large number of drying plant, but these plants are mainly concentrated in a few regions. Focus a lot of low-level enterprises have an important reason is easy to imitate. Dozens or even hundreds of companies producing the same model, resulting in you can do I can do, you can not do what I could not do. Each of brochures, exactly the same information, content strikingly similar to the patented product is rare. The result of this situation can be imagined. Innovation is the only antidote to "know only then there is definite", to solve the existing problems the industry, the whole industry from costly dilemma imitate each other and escape out of the price war, only wholeheartedly from fundamental research, starting field of automation technology, meticulous practice their capacity for independent innovation. Basic research is the basis for the development of new technologies, only the development of drying technology to promote the progress of drying equipment. China should establish a research base on a dry basis universities and research institutes. Depth study of the drying mechanism, the theoretical basis for technology development, this will make our drying equipment gradually embarked on the road of independent innovation. Low domestic drying equipment automation, control means is a common problem behind. On the current level of automation to solve the control problem of drying equipment is not difficult, but most lack the self-control technology combined with reasonable drying equipment problems. As mentioned earlier, different materials require different dryer. Similarly, the control means different material requirements are quite different. Automatic control of the dryer in the role we all know, but the question of its one-time investment is one of the most concern, sometimes even more than the investment control equipment investment dryer mechanical parts. For dryers, drying process control scheme requires reasonable certainty, to determine the appropriate means of control specific drying process, is currently in the research should be carried out.
