The Rotary Cone Vacuum Dryer (RCVD) is ideal for drying materials that cannot withstand high temperatures, are easily oxidised, volatile and must be recovered, and are heavy irritants and poisonous in nature. RCVD integrates during service under vacuum, thanks to advanced technology. Complete solvent recovery allows for improved drying performance, low-temperature operations, and process economy with the RCVD. It facilitates GMP-compliant work by ensuring optimal dust management while also providing benefits such as effective material charging and discharging. Large lumps are first broken and then powdered in the drying machine, which is fitted with lump breakers (in a single cone). The dryer’s rotary action, combined with the breakers’ mechanical action, reduces drying time and results in a lump-free product. Bharat Process Equipment (BPE) provides a wide range of capacities in all material grades, ranging from 5 litres to 20000 litres.
A rotary vacuum dryer is a cylindrical, horizontal, rotating hollow-motioned shell. A batch, vacuum drying, heating through the jacket. A batch operation. The drier provides a simple but effective way to dry wet cakes and slurries sometimes. Thanks to vacuum and agitation, heat-sensitive materials can be dried.
