Practical considerations with other units on the market vs the EVS2000
I helped my friend distill 5 liters of Rosemary in her big expensive "classic" steam distiller,
and after running 5 hours, all we got was a few drops of oil
The EVS2000 system is so efficient that it usually completes distillations within an hour and captures virtually every drop of essential oil without letting any escape. Over and over we've heard people report getting amazingly better yields with this system.
(The above instance was reported by a happy customer who reported getting almost ten times more rosemary oil in an hour from a single 2 liter run with our system than with 5 liters of it in her friends' big system over a 5 hour run !!)
Lots of water always condenses in the biomass flask™, especially before the system is fully warmed up- it's unavoidable, and as it
accumulates, it eventually covers up a lot of the plant material I'm trying
In the EVS2000, any water that condenses in the bioflask™ during warmup simply drips back down into the boiling flask to
be reused, instead of accumulating in the biomass flask™ and causing your
plant material to become flooded and no longer in contact with steam. The EVS2000 vertical design insures that the entire biomass™ stays dry and in contact with steam.
I have to constantly add water to the steam generator flask as my distillation proceeds.
Because any water condensed in the biomass flask™ is returned to the boiling
flask, the EVS2000 can go for three hours or more without having to add new
water to the boiling pot. There's a ground glass stopper in the side of the boiling flask to make water addition very easy, in case you need to.
In most cases, the EVS2000 system is so efficient that it completes distillations within an hour and uses less than 1/2 liter of water to do so
The distiller takes up the whole room, it's so big and spread out.
Our vertical design is very compact and occupies a very small area of your kitchen sink!!
Uncondensed steam occasionally comes out of the end of the condenser...isn't
this potentially loosing precious oil? (YES!!!....)
Unlike systems with vertical "up-going" or traditional 105 degree angled condensers
from which uncondensed steam can often escape, the EVS2000 has a vertical "down-going"
condenser in which the steam is forced straight down. This insures excellent agitation and complete
condensation with little chance of steam or product escaping
Some systems plop the biomass™ right into the boiling water...
Can't that heat things above
water's boiling temperature (100c) and possibly damage delicate oils? (YES!)
EVS2000 is an "opened" system, and allows only steam at atmospheric pressure
to touch the biomass™, meaning that pressure and/or temperature cannot build
up, thus eliminating any possibility of excess temperatures burning your product. The biomass™ never gets hotter than 100 degrees C under any situation.
