The Rollomat® system, initially developed in 1989 by KAISER, covers the widest viscosity range of all rotating pastillators.
The Rollomat® rotary depositor has an operating principle similar to a gear pump. The heart of this system is an inner-geared, hollow cylinder with nozzles positioned between the teeth. Along the lower portion of the hollow cylinder a pressing roll engages with the teeth of the hollow cylinder and the product is fed at the designated rate through the plug-in lance.
From there it flows onto the rotating pressing roll and gets sandwiched between the outer cylinder and inner pressing roll. Each time the teeth of the hollow cylinder engages with the teeth of the pressing roll, product is pushed through the nozzles and drops onto the cooling belt.
The Rollomat® has a heated product scraper (refeed bar) ensuring the outer surface of the cylinder is clean upon reaching the drop-off point.
