Surface Kettle Scraper-Solvent Condenser

Roto Evaporator

Solvent recovery, and substrate concentration, is required across a wide range of industrial applications. The Deutsche Process Surface Kettle Scraper-Solvent Condenser Receiver (SKS-SCR) is an industrial style, single-stage evaporator/condenser intended for bulk solvent recovery in sanitary food, chemical, nutraceutical, and pharmaceutical applications. The SKS evaporator is designed for bulk evaporation and separation of liquid solvent from higher boiling liquid or semi-solid substrates. The SKS is paired with a solvent condenser receiver, for solvent reclamation and storage. The SCR condenses vapor from the SKS evaporator and stores the reclaimed liquid solvent until it can be drained or pumped from the solvent recovery skid. The SKS-SCR solvent recovery system can also be upgraded to operate in semi-continuous (multi-batch) operation; in this configuration feedstock solution is continuously metered into the SKS and continuously discharged from the SCR. This maintains maximum solvent recovery rates and allows the concentrate volume to build in applications where dilute feedstocks are expected, such as bio-botanical extraction.
