Drum drying was used since the 1900s for drying liquid material before the development of spray drying methods. Currently, they are being used for drying many foods and pharmaceutical products such as dairy, baby formulations, and fruit and vegetable pulps.In this method a thin layer of material is applied on the surface of rotating drum(s) which are heated …
Figure 1. Kumera Steam Dryer, 240t/h feeding capacity for copper concentrate. Other reasons to select indirect steam drying instead of direct heated drum dryers are lower specific energy need in drying and smaller off-gas cleaning plant. The heating elements The modular type steam tube arrangement (Figure 2) makes it possible to modify the heating
With the ANDRITZ Gouda drum dryer, running costs are significantly lower than with other dryers. Its high thermal efficiency translates to steam consumption of approximately 1.4 kg for each kilogram of water evaporated. Drum drying is environmentally friendly as well, with low levels of dust emission, thus avoiding the
b. Vacuum Drum Dryer: A vacuum dryer allows for drying at lower temperatures by operating under vacuum conditions. In a Vacuum drum dryer, two steam-heated drums rotate within an airtight casing under a high vacuum. The liquid is introduced between the drums from the top, dried, and then scraped off before the drums complete a full rotation.
The technology represents an innovation in sludge dewatering technology as it improves energy efficiency by consumption of low-grade steam for the drying process (Horttanainen et al., 2017).
