The ring dryers are equipped with a centrifugal classifier for sifting dried products and semi-dried products. The dried product leaves the dryer where the semi-dried product is internally recirculated for extended drying.
The dryers incorporate our in-house designed equipment such as fans, screw conveyors, cyclones, and/or filters. This equipment has proven itself over many decades as part of our dryers and conveying systems as well as loose supply items for various processes.
SiccaDania ring dryers are suitable for drying difficult products and can handle the sticky feed as long as it is pumpable. The ring dryers can be fitted with in-line disintegrators for milling and mixing.
The process stability is ensured over the full operating range including swift and bumpless startup to full operation and turndown. If it is necessary, the equipment can be equipped with our proven control systems which can include:
- Condition monitoring
- Process control
- Safeguarding
Key features of SiccaDania ring dryers:
- Removal of surface moisture and bound moisture.
- Extended residence time due to internal recycling of heavier wetter particles.
- For heat-sensitive products or products less sensitive to heat.
- Internal recycling of product to a specific temperature section of the dryer for optimum product quality.
- Possibility of internal coating of the wet feed with external recycle material.
- Fit for the purpose by using our own Siccadania equipment such as fans, cyclones, filters, and screw conveyors.
