The centrifugal atomizer uses a motor to drive a speed increaser to drive and adjust the rotating impeller, and atomizes the liquid to a droplet group of tens of microns by means of centrifugal force. This is how a rotary spray dryer works. The characteristics of this type of machine are: large flow rate, not easy to block, stable operation performance, less energy consumption, large production capacity of a single machine, and uniform product size. Therefore, it has become the mainstream model in the spray dryer.
With the sound and rapid development of my country's economy, and the development of new products and new technologies in food, biochemical, fine chemical, biological and other industries, people's requirements for material quality of life are getting higher and higher, especially after my country's accession to the WTO , the international market has higher requirements for my country's drying equipment industry. However, as far as my country's current drying technology progress is concerned, the overall technical level is still lagging behind, and it is difficult to meet the needs of related industries due to economic development, product optimization structure and new product development.
Due to the late start of food machinery in my country, there is still a certain gap between the spray dryers currently used in China and similar foreign equipment. Most of the foreign drying equipment adopts automatic welding technology, the welding seam is polished, and the surface of the equipment is also polished or passivated.
If we want to shorten the gap with foreign countries, we can only make improvements in terms of equipment intelligence, processing methods, and processing quality. The future development of the spray dryer will be based on the in-depth study of the drying mechanism and drying characteristics of materials, and the development and improvement of spray dryers under the condition of mastering the optimal operating conditions for different materials.
The future development of the spray dryer will be based on the in-depth study of the drying mechanism and drying characteristics of materials, and the development and improvement of spray dryers under the condition of mastering the optimal operating conditions for different materials. In addition, large-scale, high-strength, high-economy, and improved adaptability to raw materials and product quality are the basic trends in the development of spray dryers.
The industry management and technology development system of my country's spray dryer is required by various industries because of the drying industry. So its development is actually the result of the joint efforts of many industries. In today's people's almost perfect requirements for drying technology, the continuous updating and development of drying technology is constantly being promoted. For the future development of drying equipment, new technologies and reforms are needed to better serve people and play a role. to its fullest effect.
The development of spray dryers should also pay attention to energy saving and comprehensive utilization of energy, as well as the development of automatic control technology of dryers to ensure the realization of optimal operating conditions. In addition, as humans pay more attention to environmental protection, improving the environmental protection measures of spray dryers to reduce the leakage of dust and exhaust gas will also be the direction that needs in-depth research.
