DEVICE FOR TREATING PIECES OF A SUBSTRATE AT HIGH PRESSURE WITH A SUPERCRITICAL OR NEAR-CRITICAL TREATMENT MEDIUM, PIECE BY PIECE OR IN BATCHES

摘要

supercritical or near- critical state of processing by high pressure in the medium to short listed one by one or in batches to be processed in the apparatus , the first pressure chamber ( 2); A treatment medium under high pressure the pressure chamber ( 2) supplied and from the piping system for discharging (5 ); And the first pressure chamber under high pressure or in a housing that is fixed in the second pressure chamber coupled to the first pressure chamber , and an electric motor for driving an actuator for performing a mechanical action in the treatment medium . In this case , the electric motors are open with respect to the treatment medium , and the medium during the treatment process of the base material is to flow through the electric motor and on its perimeter to enable access to the processing arrangement and design medium .
