GZG series tube bundle dryer is an indirect heating type dryer, widely applied in drying loose materials without too much viscosity like powder, particulate, and bulk solids in chemical, light industry, food, and beverages industries. It is especially an ideal for drying corn germ, corn fiber (corn residue), and protein powder. This kind of tube dryer operates with little energy consumption, obvious drying effect, and high production efficiency. Both continuous and intermittent working modes are available for option. Users can apply it in drying materials with high water content. The successful development of GZG series tube bundle dryer is an innovation in Chinese drying industry.

Weitai provides more than 20 types of tube bundle dryers, which are diversified in specification from 40㎡ to 1500㎡. Clients are welcome to choose the required one according to their scale of production.
