In processes involving the use of ejectors in the more specific pharmaceutical and foodstuff fields include lyophilisation, vacuum packaging, fruit juice concentration as well as sugar and syrup production processes.
In most cases, the intaken fluid consists almost entirely of steam and the term "thermocompression" is widely employed to define the ejector performance; actually, the intaken steam undergoes to a real compression at the expenses of the motive steam.

An interesting application of thermocompression occurs in compression-type sea water desalting units, where the "booster ejector" can suitably replace the mechanical compressor.
The use of ejectors for the discharge of the incondensible substances present in steam condensers is well known; a similar function is entrusted to SCAM ejectors running in sea water desalting units for distillation purposes.
