As a main product of our company , spraying drying set is a kind of centrifugal or pressurized , which atomizes liquid materials such as solution , suspension , emulsion or paste into timy droplet ( surface area increased ) and dry them into powder product an once ( several to dozens of seconds ) by contacying hot air 喷雾干燥机组是一种用离心式或压力式雾化器，将溶液、悬浮液，乳浊液或浆料等料液雾化成细微液滴(表面积显著增大) ，经与热风接触得以急速干燥（几秒到几十秒） ，从而直接得到粉末产品的装置。
( 3 ) the most principal factors that influence the supersonic atomization process include the flow ratio of the gas - liquid metal ( gmr ) value , the flow of atomizing of gas and the range of the inverse vortex taper . the more of the value of three factors , the more advantage they are for the atomization and the more fine the powders are .
