2018-05-11 01:00:41
Although China has a large number of drying equipment factories, the level of drying equipment still has a large distance compared with advanced countries. This is the consensus view of the industry. How to improve the level of drying technology in China as soon as possible. Coping with competition from all aspects after China's entry into the WTO is the most important issue for the drying industry. Combine the views of many experts on the status quo of China's drying industry put forward the following recommendations.
1. Strengthening basic research work For many years, domestic drying equipment mainly lacked its own characteristics as a generic equipment. It was less competitive in the international market. The level of drying equipment first depends on the drying technology. The current state of our country is that there are many manufacturers of drying equipment, but fewer people research and develop drying technology. However, the number of drying equipment manufacturers in foreign countries that have engaged in the development of drying technology has even surpassed the number of manufacturing personnel to win the market with high technology. If you want to have a certain degree of competitiveness at home and abroad, you must establish a development base with a high level of professionalism and complete experimental means. One of the effective ways is to establish an integrated scientific research and production organization to carry out scientific research and armed production, and to support scientific research to improve the technical level of drying companies to enhance the technological content of products and production potential. In the process of technology development, we mainly pay attention to the following:
(1) Strengthening basic theoretical research Basic theoretical research is the basis for the development of new technologies. Only basic research in the drying field can be used to develop the drying technology in order to promote the progress of drying equipment. The basic research laboratory equipment with complete control means should be established in our country's universities and research institutes to establish a basic research base for drying. In-depth study of the drying mechanism has laid a theoretical foundation for technological development, which has enabled our country's drying equipment to gradually take the road of self-innovation.
(2) Research on physical properties of materials Drying can not be separated from the characteristics of the material being dried and the requirements on the products are different in the drying process. Due to the difference in the nature of the materials, the complexity of the drying equipment and the diversification of the structure of the dryer are also formed. It is not difficult to master the drying mechanism and equipment structure of industrialized drying equipment. The difficulty is to adjust the equipment structure for specific materials to meet the requirements of the materials to be dried. The technical personnel of the drying equipment factory mainly learn about mechanical equipment. They often regard the drying equipment as a purely mechanical product. The limitations of the professional make it less equivocal to the physical properties of the material. The defects in the control of the material properties lead to unsatisfactory equipment. Therefore, a successfully designed dryer is first of all a correct understanding of the material and then a reasonable mechanical design. Therefore, the amount of drying equipment design personnel should pay attention to the study of the physical properties of materials.
(3) Research on automation control The low level of automation of domestically produced drying equipment and the backwardness of control means are common problems. It is not difficult to solve the control problem in the drying equipment at the current domestic level of automation, but the lack of a reasonable combination of self-control professional and drying equipment. It was mentioned earlier that different materials have different requirements for dryers. The same material has different requirements for control methods. The role of automatic control in dryers is well known, but its one-time investment is also a matter of most concern to people. Sometimes the investment in control equipment even exceeds the price of the mechanical part of the dryer. If the scheme is unreasonable or fails to meet the process requirements or causes investment waste, these are the concerns of investors. It is necessary to determine the proper control method for the dryer and the drying process to determine the proper control method for the drying process.
(4) Research on the drying of high value-added special materials In recent years, various new materials have been successively developed and successfully covered all aspects of national production. Many new materials have the characteristics of stable product quality, strict control of the drying process, strong processability, and high value-added materials. The emergence of new materials also presents new challenges for drying technology. Such as ultra-fine powder, liquid material made of large viscosity when the powder, nano-material drying, micro-capsule powder preparation and so are drying problems need to be solved.
(5) Study of amplification effect: The amplification process of drying equipment is not a simple geometric amplification involving fluid mechanics, mechanics, thermodynamics, heat transfer, material science, dust and corrosion protection, and electrical control. It is very likely that some problems will arise during the amplification process. Therefore, the enlargement of the drying equipment is by no means a simple geometric enlargement. In this respect, it largely depends on the experience of industrialization, the mastery of the physical properties of materials, and the understanding of drying equipment. The phenomena that may occur during the amplification process should be rational and objective predictions and can propose corresponding solutions. The so-called research amplification effect is to grasp the drying theory and drying technology while paying attention to accumulating practical experience and summing up the amplification law of the equipment to accumulate experience for the project.
2, improve the user's ability to identify the drying equipment China's drying plant so many and can occupy a place in the market. It should be said that the equipment produced in many drying equipment factories has certain differences in both technology and product quality. However, why can it survive? This has a lot to do with the ability of domestic user groups to set up. Drying equipment is different from other general-purpose equipment except for the externally visible factors such as the mechanical quality. The technical content and the use effect cannot be found by users. Due to the poor user's ability to identify the dryer, objectively, some lower-level drying equipment manufacturers are provided with room for survival. Cultivating market popularity of dry knowledge can play a positive role in purifying and integrating the market. Only in this way can the manufacturers with development potential survive and develop through the survival of the fittest. Although the drying equipment is a special product, it is not impossible to identify its advantages and disadvantages. The user should deal with the drying equipment factory as follows when selecting the drying equipment.
(1) Inspection factory First, the equipment factory shall be inspected to find out whether the laboratory has experimental equipment and whether or not there is experimental data for this material. Listen carefully to the report of the factory's experimentation. Understand whether there is a manufacturing capacity for the required model. Whether the processing method of the factory is full or not is required to listen to the factory's method of processing the model.
(2) Work performance The level of the factory depends to some extent on its work performance. In general, the more work performance, the stronger the equipment manufacturing capability. Because the technology will continue to improve through the manufacturing equipment. If it is the first time that the model is manufactured, users must be cautious about the maturity of the technology.
(3) Factory reputation Drying equipment should be maintained frequently and users sometimes have problems that are difficult to solve during use. Some consumable parts have no universality. The factory can provide users with technical advice forever. Parts supply must be considered by the user when selecting drying equipment manufacturers. The other users of the plant should be visited to understand the reputation of the company.
(4) Examining the same type of machine It was mentioned earlier that the drying equipment may also have such or that problem during the amplification process. It is necessary to examine whether the factory has the experience of the same model and the same specifications required by the manufacturer. If you accumulate experience in this area, the success rate of equipment is relatively high.
(5) Examining the drying effect of the same or similar material If further investigation is conducted, the best equipment factory can provide the drying experience of the same material. This will increase the credibility of this project even more. Despite this fact, it is very difficult to grasp mastery of non-professionals in a short period of time. If possible, it may be better to employ a drying expert in the inspection of the project to improve the reliability of the selection equipment factory.
