Definitions
- the rim of the drying chamber is formed as a plane surface substantially perpendicular to the axial direction, and the closing surface of the chamber roof is also designed as a plane surface.
- the seal ensures the required tightness at the interface between the chamber roof closing surface and the drying chamber rim during operation.
- the seal of the above-identified spray dryer is provided as a specially configured sealing lip of silicone positioned in a track of the rim. The sealing lip is exposed to the product processed in the spray dryer and to relatively high temperatures during operation. Although the silicone sealing lip provides for excellent tightness under normal circumstances, it must be ensured that it is safely retained in the track when opening the chamber roof.
- Fig. 1 is a front perspective view of a spray dryer in an embodiment of the invention
- Fig. 9 is a sectional view corresponding to Fig. 8;
- Fig. 10 is a partial sectional view of the detail marked X in Fig. 9, on a still larger scale;
- Fig. 13 is a partial view corresponding to Fig. 3, on a larger scale.
- the spray dryer 1 comprises a drying chamber 2 and a chamber roof 3.
