Hot air penetrates the belt from top to bottom or from bottom to top, and this will complete the heat and mass transfer process. Moving speed of belt is adjustable. The top and bottom circulation units can be freely equipped according to customer's requirement.
Being adapted the heating way of jacket and inner stirring at the same time, its heat conducting area is large and its heat efficiency is high.
