Those links are very light on information.
After pressure cooking y ou must ferment the liquid before you can distill it.
As itis you have a lovely lot of liquid witha potential for alcohol, but no alcohol.
get a beer fermenter, and a pack of brewer's yeast and brew it up. If you want a higher yield refer to my earlier post about using the Amylase enzyme contained in malt to enhance the sugar content of your brew. It is sugar that makes alcohol, not starch.
When it is fermented out, get a pot still, and distill the wash.
You will get on the first run a liquid of about 40-50% alcohol and it will taste a bit rough.
Measure the volume, then put it back in and run it through again. It should come out at around 70% or so.
Collect the first 5% AND USE IT FOR STARTING FIRES OR CLEANING, DO NOT DRINK IT!
Omitting this step is what makes backwoods moonshine dangerous.
When the alcohol content gets low, it will start to smell and taste a bit off. Stop right there, quality is more important than quantity. You might get another little bit of Vodka but it will be rubbish stuff full of higher alcohols and fusel oils. Good if you want a hangover...
If you are really keen for the extra good stuff, cut it with water to 40% and distill a third time.
Age it for as long as possible, at least a week to take some of the fire out of it, then mix to 40% with good water, preferrably spring water or distilled or pure rainwater, then enjoy.
If you want to get technical you can use a reflux still, which will do it in one pass. Don't run it at full reflux though or it will come out at 95% alcohol and strip most of the flavour with it. Don't really want it coming out at more than 80-85% tops.
If it is a bit fiery, put a teaspoon of activated charcoal in each quart and sit for a week then strain it off through a coffee filter. Makes a bloody world of difference!
