Design of a chamber dryer for sugar cubes drying (Javid Azizov)


Thiết kế buồng sấy để sấy đường (Javid Azizov) - 63 Trang.

Using laboratory dryer and doing measurements in order to get new design of chamber dryer for sugar cubes drying. Specification of drying time according to these measurements by dewatering sugar cubes moisture content from 2% to 0,1%. Finding out the amount of heat for heating aims and fan. By using Autocad program drawing basic design of both Belt and Chamber dryers.
