I have just done a very simple mod that has improved condensing.
I have a squirrel and a quad condenser but I get vapour after the condenser. The condensate drum is sealed.
I just added a length of tube so that instead of dripping into the drum the liquid and vapour is introduced under the cool condensate. Result - no vapour drawn back into the processor.
Now tell me "we all do that, didn't you know"!

Be warned, there are drawbacks doing it just that.
It's possible to collapse the reactor due to a vacuum forming on cooling once you've emptied it.
You MUST make sure the reactor has as many valves open to atmosphere as possible once drained.
Oh ye' did it years ago as have a few others.
Nothing new in the bio world.
