Spray dryer for corn starch in foodstuff industry

The machine adopts full seal from. All parts are made of stainless steel. It is equipped with three grades of filter. The filtered air is one hundred thousand grades. The cooling device of wall is installed at the cylinder body. It makes the wall temperature less than 80° C. Air sweeping device is installed inside the drying tower. The product will not be burnt or deteriorated even stays on the way. The collection rate of powder is raised greatly. Moreover will not cause medicine mixed or wall stick.


Basic Principle: High-speed centrifuge atomizing for the extract of traditional Chinese medicine is an application of centrifuge atomizing technique. It is an high-speed atomizing dryer. The following problems are solved.
