Attention should be paid to the development of China's drying equipment industry

at present, China can basically manufacture the conventional drying equipment required by the domestic market and the main drying equipment required by the international market, which shows that the history of China's mainly imported drying equipment has ended. But there are still some problems and hidden worries

existing problems

according to the prediction of China General Mechanical Drying Equipment Industry Association, the demand for drying equipment in China's chemical industry will reach about 3000 sets in the next few years; The annual demand for pharmaceutical drying equipment will reach about 3000 sets; The annual demand for drying equipment for agriculture, forestry, grain, light industry and other industries is expected to reach about 5000 sets. At present, the constituent equipment of impact testing machine has occupied more than 80% of the domestic market. It is estimated that during the Tenth Five Year Plan period, the domestic drying equipment will occupy more than 90% of the domestic market. At present, the existing problems are mainly manifested in regional concentration and weak technological innovation ability

centralized distribution of enterprises

most of the manufacturing enterprises in China's drying equipment industry are gradually derived from the early enterprises in the industry, with relatively concentrated geographical location and serious defects in personnel structure. So far, the enterprises are mainly distributed in Jiangsu, Zhejiang, Shanghai, Liaoning and Heilongjiang. The enterprises in these regions account for almost 50% of the total number of the whole industry. In sharp contrast, there are no drying equipment manufacturers in some regions of China. There is fierce competition in the industry. Some enterprises pay attention to immediate interests, lack systematic development ideas, and the overall quality is slowly improved, which seriously hinders the normal development of the industry

After the reform and opening up, especially in recent years, China's economic growth potential has been effectively released, the supply-demand relationship formed by the shortage economy has undergone a fundamental change, and the buyer's market has initially taken shape. Under the pressure of the buyer's market, some enterprises are catching up with the market rather than looking for and developing the market. Enterprises focus on the mature products with more market demand in the near future. Therefore, the manufacturers of ovens, vibrating fluidized beds, spray dryers and other products are concentrated, and the competition is extremely fierce. There are few enterprises engaged in the development of drying equipment in the industry. The improvement of new products and the introduction of new products mainly rely on mutual imitation

at present, China's drying equipment market is dominated by medium and low-tech products. The increasingly fierce competition requires our enterprises to improve product quality through technological progress, absorbing foreign advanced technology and independent innovation in order to meet production needs. From the development direction of drying equipment at home and abroad in recent years, there are mainly the following trends:

1. The comprehensive application of several heat transfer forms enables it to give full play to the advantages of various heat transfer forms at different stages of drying and make the equipment more reasonable in energy use

2. Large scale development of equipment. Any production has the best economic scale, and the scale-up technology of drying equipment can ensure large-scale production. Therefore, the large-scale research of equipment is one of the development directions in the future

3. Specialization of drying equipment. It is well known that the drying equipment is non-standard equipment. The reason why it is non-standard equipment is that there are great differences in the physical properties of materials and product requirements. Therefore, a truly designed drying equipment can better play its role, which is of certain significance from technology to economy

4. Development of multi-stage and combined drying system. Different types of drying equipment can be applied to different materials or different drying stages of materials. Combined drying can optimize the drying process to the greatest extent and make the drying system more reasonable

5. Multifunction of equipment. Nowadays, the drying equipment is not only limited to drying operation, but also integrates crushing, grading and even heating reaction into one machine, greatly shortening the production process and making the equipment multifunctional

development suggestions

adopt advanced technology to improve product quality

there is still a certain gap between China's drying equipment technology and its counterparts in developed countries in the world. At present, medium and low-tech products occupy a leading position in the market. After China's entry into WTO, more international peers will enter the domestic market. With the increasing international competition, we will face great competitive pressure. World famous drying equipment manufacturers, such as Nero group of Denmark and ohigawa Corporation of Japan, have set up branches in China one after another to seize the Chinese market

with the acceleration of economic globalization, more and more multinational companies will shift their targets to the Chinese market. The increasingly fierce competition requires our enterprises to improve product quality through technological progress, absorbing foreign advanced technology and independent innovation. The idea of product development should focus on the large-scale equipment, the degree of automation of control, the quality of equipment surface treatment, the selection of corrosion-resistant materials, and the development of multi-functional combination machines to promote the continuous extension of product life cycle. Trade associations should organize more enterprises to participate in international technical exchanges, absorb the latest technological achievements, and accelerate the improvement of the technical level of the whole industry

adjust the enterprise structure and cultivate the core competitiveness of enterprises

the characteristics of China's drying industry are that the enterprise is small, not strong, not specialized and not precise. There are a large number of non vulcanized sheet tensile control experiments and the overall quality is not high; The safety and reliability of the equipment with more hydraulic skills are good. The management of several enterprises is backward, and they have not reached the appropriate economies of scale. They should be guided and coordinated by the industry associations to change the situation of blind development. Enterprises in Jiangsu, Zhejiang and Shanghai, which are relatively concentrated, can consider using joint ventures, cooperation and acquisitions to migrate to the central and western regions, looking for a broader space for enterprise survival and development. Enterprises in the industry should take the road of strong alliance, and cultivate some large companies and enterprise groups with strong technical strength, famous brands and independent intellectual property rights in the industry. Form their own characteristic products and services

the innovation ability of drying equipment manufacturers in China is low, and few enterprises can launch new technologies and products with independent intellectual property rights, which is an important reason for the slow development of drying technology in China. At present, there are dozens of universities and scientific research institutions engaged in the development and research of drying technology, which are distributed in the East, West, North and south of China, but most of the knowledge achievements have not been effectively transformed into practical productivity. To become the main body of technological innovation, enterprises should directly cooperate with these universities and scientific research institutions in various forms, so that resources can be reasonably allocated and utilized, and the innovation ability of enterprises can be effectively cultivated and developed
