The development and application of spray dryer in dairy industry

In the production of dairy products in China, the proportion of milk powder production is very heavy, because the milk powder is easier to store and transport. Drying is one of the important links in the production of milk powder. Production process can determine the production of equipment and control systems, but the application of advanced equipment and control systems can also change the production process, spray dryer is a typical example.
Development of spray dryer in dairy industry
It is the first time that the spray dryer was used in the production of milk powder industry in 1901. But it was not until the end of the 1940s that our country began to use it. The structure of the earliest is belonging to the pressure box (horizontal), material for double atomization style, large amount of power consumption. By 1958, the Ministry of light industry in Heilongjiang province to promote the production of milk in small animal pressure spray drying method, Harbin Songhua River in 1955 for the first time the production of milk milk factory by centrifugal spray.
These two forms of spray dryer were flat bottom structure, the powder is intermittent, each work a shift out of the powder once.
With the development of time, in the middle of 1960s, the drying equipment industry has introduced new products. Then in the early 1970s, the first vertical multi nozzle pressure spray dryer was born, it makes the device to reduce the effective volume of nearly half, and do not have to stir the dragon, continuous powder.
Keep the good momentum of development, in 80s there was a more advanced drying equipment, it is a single nozzle vertical pressure spray dryer and its application in milk industry is a key link to promote milk industrial technology progress in China, laid the foundation for promoting the rapid development of China's milk industry.
With advanced technology and spray dryer protection, the quality of China's milk industry has been improved. The production of milk powder for uniform products, without drying, jelly, grinding process, can be directly used for packing, the production process of milk to achieve mechanization and continuous and large scale, and because the material surface temperature is not too high and improve the quality of milk products.
It can be said that the spray dryer to create a new era of milk powder industry, in the production of milk powder industry plays a crucial role.
