A New Craft Route of Prophase Powder Drying-Granulation Grain Drying Using Microwave Energy
Xi Tianpeng Liu Chuanyi He Shian(Nanjing University of Technology, Nanjing, 210009)
This article tried to establish a new craft route of prophase powder drying-granulation- grain drying using microwave energy by discussion powder drying and the powder granulation and grain drying techniques etc. At first , the material would be traveled to be dried in the stage of constant drying speed , and the most part of humidity of the material would be removed and then it would be become material that had humidity lower than 20% (wet). The material with low humidity would be granulated under pressure. At this time , it was not only to be granulated easily but also its rate of granulation and the strength of grannles were higher. The grains with low humidity would be dried by microwave energy. The characteristics of microwave drying was to get the merchandise with requested qualified and humidity by making the wet quickly removed from granules material .The article has discussed completely the science, the advanced technology, the possibilities and the economic of the new craft route.
