I think that is a modern coffee or espresso machine.
Yes your right the coffee is made in Hydrogen atmosphere under ammonia ans Trimethylindium flow.
Can you show us an example please?
OK, I'll try
For the inspiration I had made my PHD studies on this reactor so it was made with blueprint

and photography.
Some example of application:
All the device made with GaAs, AlAs, InAs and alloys (not Si) are made with MOCVD system.
You must well known this devices: Yellow to Infrared diodes, laser diodes and photo-detectors. High frequencies component of your cell phone are also made by mocvd...
New devices like Blue (and UV) diodes ans laser diodes made with GaN, InN, AlN and alloys are also made with MOCVD equipment (the reactor I've modeled (AIXTRON R&D equipment) is dedicated to nitrides growth and can go up to 1200°C under corrosive atmosphere).
And now Kosmokrator is your avatar an MOCVD devices???
Sorry for my poor English
