• The section where tha vapors are fed to the column is called the bubbler section.
• The vapors are fed throug the 3/4" VAPOR INLET and bubble in the liquid filling the entire section causing the ethanol concentration to DOUBLE due to the stripping effect of the liquid.

Bubbler Section: Baffle plate

• Below the lower end of the vapor inlet piping is the BAFFLE PLATE separating the bubbler and the low proof run off pipe.
• The main purpose of this plate is to prevent overflow inrush that may cause excessive low proof run off, and loss of precious beer and ethanol.
• The less evident yet the most important purpose of this baffle plate is to prevent a steam blow off through the run off water vent, in the event of a column blockage that would cause a sudden increase in the pressure of the bubbler section.
• This type of blockage may never happen, but just like the seat belt of your car, that will never be used... 
• You will be happy to have followed directions thar seemed ridiculous and futile, because the hot steam shooting out the run off water vent will hurt someone very badly.

Bubbler Section: Baffle plate sub-chamber 

• The BAFFLE PLATE SUB-CHAMBER is filled with copper brillio pads ( pure copper scrubbing pads )
• Or stainless steel brillio pads ( pure stainless steel scrubbing pads )
  • NOTE: The term BRILLIO PADS is a common name for pot scrubbers.
  • For packing the Baffle plate sub-chamber, please use only pure Copper or Stainless stell scrubbers.
• Unwrap the metal pad, and roll the mesh around the plate holder until the entire area is full of loosely packed mesh.
