What controls the reflux in distillation?

Reflux in beverage distillation By controlling the temperature of the condenser, often called a dephlegmator, a reflux still may be used to ensure that higher boiling point components are returned to the flask while lighter elements are passed out to a secondary condenser.

What is a bubble plate still?

Bubble Plates and Bubble Caps for Distilling. Bubble plates are used to create more reflux in the column, ultimately to create multiple distillation cycles during one run. In review, a distillation column is phase change occurring over and over until it reaches the final the final condenser.

What is a Boka still?

The Bokakob (Boka or Bok for short) is the common name for a Dual Slant-Plate Single Column In-line Reflux Still designed by Alex Bokakob in 2001. The still was originally designed with a fairly small reflux column to sit atop a stove-top boiler, and has seen significant modifications and improvements over the years.

How do I distill my own water?

The process of distilling is simple: Heat tap water to the point that it turns to vapor. When the vapor condenses back to water, it leaves behind any mineral residue. The resulting condensed liquid is distilled water.

How do you get distillate out of a reflux still?

These plates will collect distillate from the condenser and allow it to exit the reflux still via the needle valve. Using the template we printed off earlier trace out the slot on the column. Use a hack saw or Dremel with a cutting wheel to cut the slot in the column.

How to build a reflux pipe still?

In this step we will cut the pipes connecting the column and condenser, along with the reflux pipes. Start by cutting a 70mm section of 15mm piping. This will connect the condenser and column of the still. Next, cut two 150mm sections of 15mm pipe. These will act as reflux points, and provide water to the condenser. Cut a 70mm section of 28mm pipe.

How to build a reflux column?

To build the Reflux column we need to assemble a few things first. 1 ½” tee, a 3″ long piece of 2″ copper pipe, a thermometer and a 2″ cap. See illustration below for further details.

What is a homemade reflux still?

In this tutorial I’m going to teach you how to make a homemade Reflux Still which is also known as a column still. This homemade still is comparable in quality to most professionally designed stills like this 8 Gallon stainless steel Reflux still but will cost you less to build. What are the benefits of a Reflux still over a Pot Still?
