HG Drum drawknife drying machine |
|
 |
|
|
HG series drum scraper drier is a cooling crystallization process, material disc melt and cooling drum contact, in the drum is formed on the surface of membrane material, membrane material and through femoral wall heat transfer between the membrane material, cooling, crystallization, crystallization of membrane material is a scraper, a sheet products.

- With steam or heat conductive oil as heat source, large heating area, uniform heating, high thermal efficiency.
- The drying rate, on the cylinder wall of wet membrane material for the heat and mass transfer process from the inside to the outside, direction, temperature gradient, so that the material film surface to maintain a high evaporation intensity
- Suitable for heat-sensitive materials, short drying time, about 10-15S.
- Simple operation, convenient repair.
