Distillation and essence extractor insert for beer brewing machine
A distillation/extraction insert may attach to a vessel containing liquid to be distilled, and may use heated water circulating through a heating coil, as well as draw a partial vacuum to induce boiling. A condensation coil may collect the vapor and condense the vapor into distillate. A controller may monitor various temperatures and vacuum level to precisely control the heated water being used to boil components in the liquid. The heated water may be created by a beer making machine, which may have a temperature controlled recirculating water system. The insert may be a self-contained unit that attaches to a vessel, where the vessel may also be used for fermenting brewer's mash for distillation. In some cases, an extraction chamber may be used for collecting essential oils from various materials.
1. A device comprising:
a heating mechanism configured to heat liquid in a liquid vessel;
a condenser connected to said liquid vessel and having a vapor collection point and a condensate exit point;
a valve connected to said condensate exit point and switchable between a collection container and a heads collection chamber;
a vacuum connection connected to said liquid vessel;
a vacuum sensor connected to said liquid vessel;
a first temperature sensor proximal to said vapor collection point; and
a controller configured to:
sense said vacuum sensor to determine that at least a partial vacuum has been achieved inside said liquid vessel and when said at least said partial vacuum has been achieved, cause said heating mechanism to begin heating said liquid in said liquid vessel;
measure a first temperature at said vapor collection point using said first temperature sensor;
control said heating mechanism to heat said liquid to match said first temperature to a target temperature; and
begin a process of distillation and determine a switchover action between heads and hearts of distillation and indicate said switchover action, said switchover action comprising actuating said valve to switch from said heads collection chamber to said collection container.

determine that an error condition exists; and
cause said vacuum connection to be vented.
3. The device of claim 2 , said error condition being an over temperature condition.
4. The device of claim 3 further comprising:
a second temperature sensor proximal to said collection container; and
said over temperature condition being an over temperature condition measured by said second temperature sensor.
