Heinkel USA has released an inverting filter with a filter cloth that is axially moveable. This allows the filter cloth to be inverted while under rotation which completely discharges the solids, leaving the filter cloth free of residual heel while maintaining a totally-enclosed gastight system.
Heinkel USA offers the HF&F model centrifuges, which incorporate inverting filter technology, thin-cake filtering and PAC direct-contact drying of the material in one machine for separation/filtration. With these combinations of technologies, it is possible to dry product inside of the gas-tight centrifuge, reducing overall drying cycle time or eliminating downstream drying equipment.
Other potential advantages include the elimination of residual heel on the filter cloth, repeatable batch quality and full flexible process recipe management.
