China's drying equipment in the automation control level, appearance quality, complete and functional composition and the foreign advanced level difference is quite big, the main problems of technical innovation capability is not strong and centralized in two aspects.

The lack of theoretical research is to restrict drying equipment development a big bottleneck. Dry material properties varied, only several drying equipment can not meet the need of production. Theoretical research is the development of novel dryer foundation, China drying technology development, must develop a number of theoretical study, drying technology development workers, to improve the technological content of drying equipments in our country. In recent years, although our country has some tertiary institutions and scientific research units are doing this kind of work, but the input of manpower, material resources is far from enough. In the aspect of theory of our country and Denmark, Canada, Japan and other countries compared to still have not little difference.

At the same time, the drying equipment industry is also a lack of a qualified experiment process. So far, no matter be drying equipment factory or theoretical research unit, without a sound experimental base. Drying is highly experimental technology, regardless of theoretical research or the drying equipment manufacturing, experimental methods are essential. Through the experiment, researchers can be summed up in the drying process of many rules, equipment manufacturing plant is determined by experiment of various process parameters. However, many units just ignored the importance of experimental. Some equipment factory did not even an experimental device, in equipment design has the very big blindness.

At present, the experimental means weak mainly in these aspects, one is the equipment manufacturing plant on the course of experimental knows inadequacy, think not essential. Two experimental device models more generally, huge investment, enterprises can bear. Build perfect experimental base of China's study on drying technology of a pressing matter of the moment. The three is the lack of experimental staff, on the results of the experiment ability. Some enterprises do not have a technical staff, equipment in the production process or even no drawings, only by mechanical processing staff estimation and experience to produce the value of hundreds of thousands, millions of dollars of equipment, this phenomenon is not uncommon in the drying equipment industry.

Instead of restricting the development of the industry and another reason is that, although there are a large number of drying equipment factory, but the factory mainly concentrated in several areas. A large number of low level enterprise concentrate has a main reason, is convenient for imitation. Dozens or even hundreds of enterprises in the production of the same type, cause you can do I can do it, you can't do what I can do. The brochures, promotional materials run in the same groove, content is strikingly similar, patented products are very rare. This situation results one can imagine. Drying mechanism for research, technological development and lay the theoretical foundation, this will make our drying equipment gradually embarked on the road of independent innovation.

Domestic drying equipment automation level is low, the control means is backward the problem that is widespread presence. The level of automation, solve the drying equipment in the control problem is not difficult, but the lack of the automatic control technology and drying equipment reasonable combination problem. Mentioned before, the different materials for the dryer requirements are also different. Similarly, the different materials of control requirements have bigger distinction. Automatic control in the dryer 's role as everyone knows, but its one-time investment is one of the most concern, sometimes control equipment investment even more than the drier the mechanical part of the investment. The dryer, drying process to determine a reasonable control scheme, according to the specific drying project to determine the proper means of control, is also currently should be the research subjects.

Independent innovation is the only antidote

" Known only then has set ", to solve the industry the existing problems, so that the whole industry from costly imitate each other and price war difficulties get out, just put one's heart and soul into the basic theory research, automation technology in areas such as starting, be strict in one's demands to cultivate their own independent innovation ability.
