Drying technology is applied to almost all industries and it is a key factor affecting product quality and industrial efficiency. At present, the drying methods of wood mainly include conventional drying, high-temperature drying, dehumidifying drying, solar energy drying, microwave drying, heat pump dehumidification and solar energy combined drying.
According to the forecast of China General Machinery Drying Equipment Industry Association, the demand for drying equipment in China will be large in the next few years, and the chemical industry will be about 3000 (sets) of drying equipment; the annual demand for pharmaceutical drying equipment will reach around 3,000 (sets); agriculture, forestry For industries such as food, light industry and other industries, such as drying equipment, the annual demand is expected to reach around 5,000 (sets). At present, the market share of drying equipment in the domestic market has reached more than 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 quality of equipment, 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.
The future development direction of boiling granulation drying machine, commonly known as the domestic one-step granulator, was based on the introduction of foreign products of the same type in the 1980s and was designed after digestion, absorption and improvement. Due to its simple operation, superior performance and excellent manufacturing, the equipment can meet the requirements of GMP regulations for 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 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.
