In the next few years, China Drying Network will have a large demand for drying equipment, and the chemical industry will dry around 3,000 (sets) of equipment; the annual demand for pharmaceutical drying equipment will reach around 3,000 (sets); agriculture, forestry, food, light industry, etc. Such as drying equipment, the annual demand is expected to reach around 5000 (sets). At present, there are about more than 500 drying equipment manufacturers in China, with annual sales exceeding RMB 3 billion, and the market share of drying equipment in the domestic market has reached over 80%. The development and improvement of dryers need to grasp the optimal operating conditions for different materials; in addition, the large-scale, high-intensity, high-cost, and improve the adaptability of raw materials and product quality, is the basic trend of dryer development; Further research and development of new efficient and adaptable special requirements of the dryer, such as combination dryer, microwave dryer and far infrared dryer. The development of dryers should also pay attention to energy saving and comprehensive utilization of energy, such as adopting various joint heating methods, transplanting heat pump and heat pipe technology, developing solar dryers, etc., and developing automatic control technology of dryers to ensure optimal operating conditions. In addition, as humans attach importance to environmental protection, improving the environmental protection measures of the dryer to reduce the leakage of dust and exhaust gas will also be the direction that needs further study. As the equipment quality, supporting components and basic research still need to be further improved, conventional drying is still the main form of drying. As each kind of drying has its own advantages and application scope, combined drying will be the trend of future development. Compared with developed countries, domestic products still have a certain gap between quality and technical level. Therefore, China's drying equipment manufacturers must continue to learn from international advanced technology, combined with practical experience, explore new technologies, develop new technologies, and come up with new products to participate in international competition. Domestic drying equipment development direction The boiling granulation dryer, commonly known as the domestic one-step granulator, was designed after the introduction of foreign products of the same type in the 1980s, and was designed after digestion, absorption, and improvement. Because of its simple operation, superior performance and excellent manufacturing, the equipment can meet the GMP requirements of the pharmaceutical and food industries, and is welcomed by users in the pharmaceutical and food industries. The device is especially suitable for drying and granulating Chinese and Western medicines and foods. The obtained particles have strong disintegration degree, good fluidity and fast dissolving property, and can be directly used for tableting, filling capsules, granules and solid beverages. Centrifugal spray dryers have achieved ideal application results in dyes, dairy products and other fields. Over the years, the equipment has been widely used, and the level of technology and manufacturing quality have made great strides. In recent years, large-scale centrifugal spray dryers have also received attention in the application of flue gas desulfurization, and the development prospect cannot be ignored. Grain drying storage equipment demand. At present, the drying and warehousing of grain has been highly valued by the state and relevant departments, coupled with the requirements of environmental protection and other aspects, China has begun to change the past granary drying mainly by natural drying, granary drying and storage Equipment began to be widely promoted. Large-scale steam sterilization, vacuum freeze-dryer steam sterilization, and vacuum freeze-dryer are key equipment for ensuring the quality of bio-pharmaceuticals. With the improvement of the people’s living standards, people are increasingly demanding vacuum-treated foods, vegetables, health products, and nutritional products that have good rehydration, good color, and good nutrition. Therefore, the demand for large-scale vacuum freeze-drying equipment needed to adapt to these products will also increase. Insufficient R&D restricts development Technological innovation is the key China's drying equipment is quite different from the foreign advanced level in terms of degree of automation control, appearance quality, completeness of packages, and functional combination. The main problems are the inability of technological innovation and regional concentration. The lack of theoretical research is a major bottleneck restricting the development of drying equipment. The physical properties of the materials to be dried are varied, and only a few drying equipments cannot meet the needs of production. Theoretical research is the basis for the development of new dryers. With the development of drying technology in China, it is necessary to cultivate a group of theoretical research and drying technology development workers to improve the technical content of drying equipment in China. In recent years, although some colleges and universities or scientific research units in China are doing this work, 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, Japan and other countries. At the same time, each drying equipment company still lacks a qualified experimental procedure. So far, neither the drying plant nor the theoretical research unit has a perfect experimental base. Drying is a very experimental technique. No matter if it is theoretical research or drying equipment manufacturing, experimental methods are indispensable. Through experiments, theorists can summarize many laws in the drying process, and equipment manufacturers determine various process parameters through experiments. However, many units just ignore the importance of experimentation. Some equipment factories do not even have a set of experimental devices. They have great blindness in the design of equipment. At present, the weak experimental methods are mainly in these aspects. First, the equipment manufacturers lack understanding of the experimental process and consider it dispensable. The second is that there are many types of experimental devices, and the investment is huge. The non-general enterprises can afford it. The establishment of a sound experimental base is a top priority for China's drying technology research. The third is the lack of experimental personnel, and weak analytical ability for experimental results. Some companies do not have a technical person, and they do not even have drawings during the production process. They rely on the estimation and experience of the mechanical processing personnel to produce equipment worth hundreds of thousands and millions of dollars. This phenomenon is not uncommon in the drying equipment industry. . The other reason that restricts the development of the industry is that although there are many drying equipment factories in China, these plants are mainly concentrated in several regions. An important reason for the concentration of a large number of low-level companies is that they are easy to copy. Dozens or even nearly 100 companies produce the same model, causing you to do what I can do. You can't do it or I can't do it. The brochures and promotional materials of each company are exactly the same, the content is strikingly similar, and patented products are rare. The result of this situation can be imagined. To solve the existing problems in the industry and enable the entire industry to emerge from the costly mimicry and price war difficulties, it is only necessary to start from the basic theoretical research, automation technology and other fields, and meticulously cultivate their own independent innovation capabilities. . Basic theoretical research is the basis for the development of new technologies. Only the development of drying technology can promote the progress of drying equipment. China should set up a basic research base for drying in universities and research institutes. In-depth study of the drying mechanism will lay a theoretical foundation for technological development. Only in this way will our country's drying equipment gradually embark on the road of independent innovation. The low level of automatization of domestically produced drying equipment and the backwardness of control means are common problems. As far as the current level of automation is concerned, it is not difficult to solve the control problem in the drying equipment, but what is lacking most is the problem of the reasonable combination of the automatic control technology and the drying equipment. As mentioned earlier, different materials have different requirements for dryers. Similarly, there are major differences in the requirements for control methods for different materials. The role of automatic control in the dryer is well-known, but its one-time investment is also the issue that people are most concerned about. Sometimes the investment in control equipment even exceeds the investment in the mechanical part of the dryer. It is also the subject that research should be carried out to determine a reasonable control plan for dryers and drying process requirements and to determine appropriate control measures for specific drying projects. unscrewing injection mold design,auto unscrewing mould,unscrewing injection mould,injection mold unscrewing,Unscrewing Moulds Dongguan Hongke Plastic Precision Mould Co.,Limited , https://www.hongkemolds.com
