Spray drying is a drying process in which the raw material liquid is dispersed into droplets with an atomizer, and hot air (or other gases) is in direct contact with the droplets to obtain a powdery product. It has many advantages, but judging from the current development status, there is still a big gap between the development of my country's spray dryer industry and the world, and there are still many problems in its development. The main reasons are as follows:
1. The level of technology is low, the quality of precision spray dryers is poor, the manufacture of high-precision spray dryers is still difficult, and core technologies and key products still rely on imports. The processing allowance is large, the energy consumption and raw material consumption of the spray dryer are serious, the processing cycle is long, and the production efficiency is low, which has become a bottleneck restricting the development of the industry.
2. There are few companies with research and development capabilities in the entire industry chain, and the willingness of enterprises to research and develop is insufficient. Spray dryer is the product of mass production technology and production process accumulation. If there is no certain research and development investment, the product will stay at the low-end level and will be gradually eliminated by the tide of the times.
There is still a long way to go in the research, development and improvement of spray drying in both academia and business.
