According to the investigation, we need to further improve the quality of the dryer equipment, the supporting components and the basic research, and the conventional drying is still the main drying form at present. Compared with developed countries, there is still a certain gap in the quality and technology level of domestic drier products. Domestic driers can be divided into boiling granulating drier, centrifugal spray dryer, vacuum freeze dryer and so on. Compared with the early days of the founding of the people's Republic of China, the development of drier in China has been developing rapidly.
Lack of theoretical research is a major bottleneck restricting the development of dryer in China. The physical properties of dried materials are varied, and only a few drying equipment can not meet the needs of production. Theoretical research is the basis of developing a new dryer. The development of drying technology in China must cultivate a batch of theoretical research and drying technology developers to improve the technical content of the drying equipment in China. In recent years, although some colleges and universities or scientific research institutions are doing this work, but the input of human and material resources is far from enough. In terms of theoretical research, there is still a big gap between China and Denmark, Canada and Japan.
All dryer enterprises still lack a qualified experimental process. Up to now, no matter the second-hand drying plant or the theoretical research unit, there is no perfect experimental base. Drying is a highly experimental technology. Whether it is theoretical research or drying equipment manufacturing, experimental means are indispensable. Through experiments, theorists can summarize many laws in the drying process, dryer equipment recovery manufacturer through experiments to determine a variety of process parameters. However, many units just ignore the importance of experiment. Some dryer plants do not even have a set of experimental devices, which are very blindness in equipment design. At present, the experimental means are weak mainly in these aspects. First, the equipment manufacturer does not know enough about the experimental process and thinks it is necessary. Two, there are many models and huge investment in the experimental device. The establishment of a perfect experimental base is a pressing matter of the moment for the study of drying technology in China. The three is the lack of laboratory personnel, and the ability to analyze experimental results is weak. Some enterprises do not have a technical personnel, and there are no drawings in the process of equipment production. It is not uncommon for the drying equipment industry to produce hundreds of thousands of equipment with millions of yuan on the basis of the estimation and experience of machined personnel.
Another reason that restricts the development of dryer industry is that although there are many dryer equipment manufacturers in China, these factories are mainly concentrated in several regions. An important reason for the concentration of a large number of low level enterprises is to facilitate imitation. Dozens or even hundreds of enterprises produce the same model, causing you to do what I can do, you can't do it, you can't do it, I can't do it either. The descriptions and publicity materials of all the houses are the same, the contents are strikingly similar, and the patent products are rare. The result of this situation is conceivable.
In order to solve the existing problems in the dryer industry, the whole dryer industry is out of the difficult position of mutual imitation and price war. The low level of automation and the backward control means of domestic drier equipment are common problems. At the present level of automation, it is not difficult to solve the problem of control in the drier equipment, but the most lack of the problem is the rational combination of the automatic control technology and the dryer. As mentioned earlier, different materials have different requirements for driers. Similarly, different materials have different requirements for control methods.
The role of automatic control in the dryer is well known, but its one-time investment is also the most concerned problem. Sometimes the investment in the control of the dryer equipment is even more than the investment in the mechanical part of the dryer. In view of the drying machine and drying process, the control scheme is determined reasonably, and the appropriate control means for the specific drying engineering is also the subject of research.
Thus, the development of China's dry equipment industry is still good, but at the same time there are some problems, which is the need to work together with the industry to improve, in order to cope with the demand of customers.
