Lack of basic research drying equipment development Time:2015-08-24
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, most industrialized models can be manufactured in China, basically reversing the situation of drying equipment is imported, but also large numbers of drying equipment manufacturers. It is estimated that China's drying equipment manufacturers are about 500, with annual sales exceeding 3.0 billion. In quantitative terms, our claim to be a world superpower drying equipment. However, the majority of our drying equipment manufacturer technical level is not high, and some even no technology at all. Number of low investment, low-tech "motley crew" to a large number of low-quality, low-cost equipment crowding the market, not only affects the overall image of China's drying equipment, drying equipment also caused the domestic price of the "infighting", thus making China dry and the overall competitiveness of the industry difficult to play.
Lack of constraints to development R & D
China's drying equipment in the degree of automation and control, the appearance of quality, feature sets and combinations of terms vary considerably with foreign advanced level, the main problem performance and technological innovation capability is not strong regional focus in two ways.
Lack of theory development is constrained drying equipment is a major bottleneck. Physical properties of the material being dried variety, several drying equipment alone can not meet production needs. Theory is the basis for development of new dryer, China Drying technology, it is necessary to develop a number of theoretical research, development workers drying technology to improve the technological content of China's drying equipment. In recent years, although there are a number of universities or research institutes are doing work in this area, but the input of manpower and material resources is not enough. Theoretical research in China and Denmark, Canada, Japan and other countries, there is still a gap.
At the same time, the drying equipment companies still lack a qualified laboratory procedures. So far, both theoretical drying equipment factory or research units, are not a perfect experiment. Drying is a highly experimental technology, both theoretical research or drying equipment, laboratory methods are essential. Through experiments, theorists in the drying process can be summed up many of the laws, equipment manufacturers through a variety of experiments to determine the process parameters. However, many units ignores the importance of the experiment. Some devices do not even have a factory experimental device, the device has a great design of blindness.
Currently, experimental methods are weak in these areas, one equipment manufacturer lack of knowledge of the experiment that is dispensable. The second is more experimental device models, huge investment, non-general business can afford. Built a sound experimental base is a priority of China's drying technology research. Third, the lack of laboratory personnel, the analysis of experimental results are weak. Some companies do not have a technical staff, equipment, production process or even drawings, alone machining personnel and experience to produce estimates of the value of hundreds of thousands, hundreds of million of equipment, a phenomenon not uncommon in the drying equipment industry.
While restricting development of the industry another reason is that although China has a large number of drying equipment factory, but these plants are mainly concentrated in several regions. There are a large number of low concentration of enterprises is an important reason, is easy to imitate. Dozens or even hundreds of companies producing the same type, cause you can do I can do, you can not do what I can not do. Each of the manuals, promotional materials exactly the same content strikingly similar, patented product is rare. Result of this situation can be imagined.
Independent innovation is the only antidote
"Knowing only the latter has given" to solve the existing problems the industry, so that the whole industry from costly price war with each other to imitate and to get out out of the predicament, the only dedicated research from the basic theory, the starting field of automation technology, meticulous practice their capability of independent innovation.
Basic research is to develop new technologies, and that only drying technology development to promote the progress of drying equipment. China's universities and research institutes to be established in the dry and basic research base.
Depth study of drying mechanism, laying the theoretical foundation for technology development, this will make our drying equipment gradually road of independent innovation.
Drying equipment made low level of automation, control, backward is a common problem. The current level of automation, to solve the control problem in the drying equipment is not difficult, but most lack is a reasonable self-control technology combined with the drying equipment problems. As mentioned earlier, the drying machines of different materials with different requirements. Similarly, the material requirements of the different means of control is also very different. Automatic control role in the dryer is well known, but the time investment is one of the most concern, sometimes even more than investment in control equipment dryer mechanical part of the investment. For the dryer, drying process requires reasonable control program, specific projects to determine appropriate control drying means, is currently the subject of study should be undertaken.
