FIELD: process engineering.SUBSTANCE: invention relates to drying of aerated cotton to be used in construction. Drying process is implemented in drying chamber. Said chamber can accommodate several lots of this material. Heat carrier is fed at drying chamber outlet while gas is discharged at its inlet at drying. Drying is performed in steps. For this first lot of this material is place at chamber inlet, in first drying zone. Heat carrier is continuously fed towards heat isolation material with discharge of used gases from drying chamber inlet zone outside, into exhaust ventilation. After first step drying, dried lot is displaced in steps towards outlet. Another lot is placed to drying zone inlet to repeat the process if required.EFFECT: non-polluting process due to intensive removal of formaldehyde.3 cl, 1 dwg |
