The current needs of the United Nations, the conventional drying equipment in the domestic market, and the main drying equipment of the international market are basically made in China, which indicates that the import oriented history of drying equipment in China has ended. However, there are still some problems and difficulties, according to China general machinery drying equipment industry association predicted that in the next few years, China demand, chemical industry will dry equipment 3000 (sets); annual demand of pharmaceutical drying equipment will reach 3000 (sets); agriculture, forestry, food, light industry and other industries. Such as drying equipment, the annual demand is expected to reach 5000 (sets). At present, the share of drying equipment in the domestic market has reached more than 80%.
  It is expected that in the period of "fifteen", China's drying equipment will reach 90% in the domestic market. At present, there are two methods of regional focus and technological innovation ability in performance problems. The most centralized production enterprises in China's drying equipment industry mostly produce early enterprises, relatively concentrated geographic location and serious defects of personnel structure on the basis of this industry. So far, enterprises are mainly distributed in Jiangsu, Zhejiang, Shanghai, Liaoning, and black. These enterprises account for almost 50% of the total industry. In contrast, there are some areas in China that do not exist in dry equipment manufacturers. Highly competitive industries, some companies focus on immediate results, do not need any system development, improve overall quality, slow progress, and seriously hamper the normal development of the industry. Technology development is not strong since reform and opening up. Especially in recent years, China's economic growth potential has been effectively released. The supply and demand of the shortage economy has undergone fundamental changes, and initially formed a buyer's market. Pressure buyer's market, some enterprises catch up in the market, rather than looking for and developing new market, enterprises focus on market demand in the near future, more mature products. Therefore, in the oven, the vibrated fluidized bed dryer and other products, the manufacturers are more concentrated and more competitive. The drying equipment industry is engaged in the development of small enterprises, new products, and the perfect introduction of new products is mainly to imitate each other. It is suggested that the development of advanced technology and improve the quality of products in China's drying equipment technology compared with the developed countries in the world, there is a certain gap in the same industry. At present, the products with low technical content are the main products in the market. China's accession to the WTO will bring more international competitors to enter the domestic market, and we will face great competition pressure with the increasingly serious international competition. The world's leading manufacturer of drying equipment, such as Denmark Nehru River Group Co. Ltd. of Japan set up a branch Chinese one after another, to seize the market China. With the acceleration of economic globalization, more companies will be targeted at the Chinese market. The increasingly fierce competition requires that we have to absorb advanced foreign technology, innovate and improve the quality of products through the progress of the enterprises. The idea of product development to large-scale equipment, control automation, quality, surface treatment equipment, selection of anticorrosive materials, development of multi-functional combination machine, product life cycle continue to extend. Industry associations should organize enterprises to participate in the international technology exchange and absorption of the results, the latest technology, to speed up the whole industry, to improve the technical level. The adjustment of the characteristics of enterprise, cultivate the core competitiveness of enterprises in China is drying industry enterprises do not, not strong, is not suitable, but not perfect, but the overall quality is not high, the majority of enterprise management is backward, do not meet the corresponding scale economy, through the guidance and coordination of Industry Association, change the blind development of the situation.
  Jiangsu, Zhejiang and Shanghai, with relatively concentrated 3 enterprises, can consider the use of the joint venture, and cooperate and acquire the central and western regions to migrate to find a wider space for survival and development businesses. The industry of industrial enterprises with strong and strong joint road has trained a number of technical strength, big companies with well-known brands and independent intellectual property rights, and enterprise groups. It has formed its own special products and special service. The relatively low innovation ability of drying equipment manufacturers in China, and the introduction of new technologies, new products, and a few companies with independent intellectual property rights, which is an important reason for the slow development, is developing slowly. At present, there are dozens of universities and research institutes engaged in research and development of drying technology, located in the eastern, Western and southern part of China, and most of the knowledge achievements have not been effectively converted into real productivity. The main body of technological innovation should be directly related to all kinds of combinations of these universities and research institutions. Therefore, rational resource allocation and utilization can effectively cultivate and develop innovative enterprises.
  The focus of the future competitiveness of the dry equipment industry will focus on product quality, technology, service and price. The type of equipment in dry, hot air will be dry air heating equipment, vacuum drying equipment based, and other devices, such as far-infrared drying, flash dryer, microwave drying equipment and other special fields, users will also gradually expand the number of applications. The demand for large standard equipment in food, medicine drying, vacuum freeze-drying equipment will increase, and the demand of combined functions, such as pellet drying, drying filter, will increase. The application of high automation drying equipment will be welcomed in some applications. In addition, the emergence of drying equipment will pay more and more attention to quality, corrosion resistant materials, drying equipment and reliable performance, which will pay special attention to users. At present, drying equipment industry entered a mature stage of development, to better meet the actual needs of users in various fields, the price of similar products abroad, only 1/3, the drying equipment than imported equipment in the market competition in Chinese price has obvious advantages; on the other hand, drying equipment is large, most involved in on-site installation, commissioning and customer service service, for domestic users, domestic equipment imported equipment more choice and more convenient. In the international market, China's accession to the WTO, drying equipment is more conducive to the expansion of exports. At present, the main export products are China vacuum drying equipment and drying equipment, drying equipment, vibration, small grain, agriculture, forestry, food and local products drying equipment, the annual export volume of more than 100 vehicles, mainly exported to Southeast Asia and other developing countries, and opened the door to the European and American markets. At present, China's exports account for less than 5% of the total dry equipment. The experts predict that the total share of drying equipment and drying equipment in the domestic market will exceed 10% during the fifteen period. International competition, dry equipment manufacturers in China's main competitors are Denmark, Switzerland, the UK, Germany, the United States and Japan. Compared with competitors, the advantage of China's drying equipment is very cheap, which is mainly due to the lack of automation, and the area of appearance quality, function set and combination has been further improved. Therefore, the domestic drying equipment manufacturing enterprises should make full use of China WTO opportunities, strengthen technical exchanges with foreign countries and learn from foreign advanced drying equipment, drying equipment, to accelerate improve the degree of automation and control China, appearance quality, feature set and combination, and to narrow the gap with foreign products, to improve we are in the trust of users, therefore, drying equipment in Chinese, not only in the domestic market, but also in foreign markets. In China, more and more varieties of drying equipment are produced, and the scale, level and quality of the products are increasing rapidly, and more and more market competitiveness. In particular, the Chinese government supports the export related policies, and produces dry equipment to create favorable external conditions for domestic enterprises, which indicates that China has good prospects for the development of drying equipment.
  Common knowledge of drying equipment: common pre dryer in our country is common spray dryer, air dryer, fluidized bed dryer, flash dryer, fluidized bed dryer, such as spray granulation. The spray drying of the flash dryer is one of the most advanced equipment in the drying equipment. Three kinds of atomization in traditional methods: rotating atomization, pressure atomization and airflow atomization. The swirling atomization characteristic has a large spray drying capacity (up to two hundred tons / hour), and will be responsible for easy control, operation flexibility and wider application. The characteristics of pressure atomizing spray drying is the coarse particles can be created, so that the day after the maintenance. Because the nozzle hole is very small, it is very easy to clog. It is necessary to filter the liquid strictly. The nozzle hole is easy to wear, and the wear resistant material is used. There is also a new structure of the nozzle pressure, called the pressure - flow nozzle. It is characterized by the nozzle pressure and the air gap nozzle in the surrounding environment. The atomization is divided into two stages: the first formation of the liquid film pressure nozzle, the film is the second air atomization, thus making more small water droplets. The advantages of this type of nozzle are: (1) adjusting the pressure of compressed air can adjust the droplet diameter and operate simply; (2) produce, high viscosity liquid, it can atomization droplet fines; 3, if you disable compressed air, the original pressure nozzle can be used. The atomizing airflow of the laboratory and the main plant in the Middle East, its power consumption. The first two liquids that can not atomized nozzles, use air atomized nozzles. Stickup, paste and filter cake materials with high viscosity can be used for atomization of three fluid nozzles. Dry air flow drying technology is mature, if the operation data can be directly designed.
  At present, a large number of dry equipment manufacturers can provide this type of equipment.
  A fluidized bed dryer for the fluidized bed dryer spray drying equipment. The feeding settings are divided into a part of a fluidized bed dryer and a heat transfer bed dryer. When solidarity is easy to use, fluidized bed drying or aggregation of powder material feed will cause more water to flow into the above difficult phenomena. This time, the feed mixer is set up above, eliminating the cluster problem to achieve normal flow. The latter is a combination of heat conduction and convection heat transfer. When the normal flow of hot air is not enough, the country will meet the required heat drying and use the heat exchanger set up to supply part or most of the heat, and which type of operation can save energy greatly. Take a variety of forms of heat exchanger. Vibrated fluidized bed drying is also often used for combined drying of secondary education and higher education. The general vibration fluidized bed is carried out, and the vibrated fluidized bed is used. A vibratory source with a flow can be divided into two types: one is driven by a vibrating motor, and the others vibrate through a vibrator to make a spring. When vibrate, the size of the bed and the latter are better. In the process of fluidized bed spray granulation dryer, the fluidization technology, the atomization technology and the organic combination of drying are three. It is the spray liquid into the fluidized bed of seeds, so the seed growth and dry, in order to achieve the required size, time outside of the catapult. The device is small and large in production capacity and can create large particles. The industrial application of the equipment has been increasing.
