vacuuming plant material for more yeild?

I know some people do multiple extractions on their material, something like a butane blast, then an iso/ethanol wash, then sometimes making butter out of what's left, in order to get the most out of the material. Would putting plant material under a vacuum before extraction help to draw out any oils to get a higher yield so that multiple extractions aren't needed? My thought are the vacuum will start to draw the oils to the surface where the can be stripped away easier. Only downside i can think of is it will probably be pulling more unwanted stuff out as well ( IE: chlorophyll), meaning a polishing might be needed.

Short answer nope it will not do anything good for you

The slightly longer answer is that the oils we seek are already on the surface in trichomes.

What i can't get my head around is how material can be processed 2, sometimes 3 , times, IE butane run, eth wash then cook it down for edibles. Are the process we are using not that efficient at stripping?

No the solvent and methods Are efficient and pulls All the oil If it is soaked for an extended period.

The multiple runs allows one to produce a Clean Heady rosin, then to a Body Buzz, to the edible... If you were to soak the whole time and Not run it through at different intervals then it would have the Clear Heads mixed with the Dark Lows, and the Common Denominator brings Everything else down with it hence it All becomes dark.
