Extractor apparatus

An extractor apparatus, comprising:

• an autoclave defining an interior extending along a longitudinal axis between opposite media inlet and discharge ports;
• a feed assembly coupled to the inlet port to supply media during operation to the interior establishing a media bed movable about the longitudinal axis through the interior to the discharge port;
• the feed assembly including a sealing end that establishes a pressurized seal against the inlet port during operation to resist solvent flow into the feed assembly beyond the sealing end;
• the feed assembly including a reciprocating piston sized to establish the sealing end about a distal portion during operation when the piston is extended into the inlet port, and arranged to actuate to at least one of:
• supply, mix, compact, and move the movable media bed to the inlet port:
• a solvent supply coupled to the autoclave proximate the discharge port to establish during operation pressurized solvent cross flow directionally opposite the movable bed;
• an extract port coupled to the autoclave proximate the inlet port to extract cross-flowed solvent from the movable media bed during operation;
• and
• a capture assembly sealingly coupled to the discharge port and to capture, during operation, spent media, and movable to discharge the spent media.
