My first thought was using my freeze dryer as a vacuum chamber, then remembered why it's programming takes it down to temperature before kicking on the pump. And a giant evaporation tower at a soda ash plant I walked down.  They pulled a vacuum on it to reduce the energy required to boil away the water.

My mind is still running.  I bet one can bypass any special equipment (in an area with tall mountains) by prepping the tinctures in the high country using a sealed jar and then aging it in the lowlands.

I am kind of an industrial process guy and a vacuum tincture sounded intriguing, but had to do a quick search because my first bit of skepticism was how I can boil a glass of water under a vacuum right until the point it freezes all at room temperature.

I found this site that talks about the process and attached a screenshot of my bit of skepticism getting squashed and confirmed.

Douglas Alpenstock wrote:Neat idea! But how will you deal with the waste? Every refinery and chemical plant I have seen produces waste byproducts. A plastic refinery is surely not exempt. These things cannot simply be dumped down the drain. Many things are hypothetically possible, but the devil is in always in the pissy details.



Very well said! There is never a free lunch.

The 3 products would be the un-condensible gas witch would be recycled and flared off into the heating process. The liquids which are the target. And then the mysterious solids which is essentially carbon black.  In theory the heavy metals would be left in the petroleum coke from the original refinement. Wish I had my own independent lab to figure out what exactly is left over.  Can think of a ton of industrial uses which are far from back yard capable. Press briquettes?

I had a recent wash out. This was an undercut that I knocked down then rocked. Failures will happen (especially when all one has is round rocks) but that's why you keep it at one rock status and play the numbers game.  If it cuts around the side the embed is cut for the next time one wanders up the wash.  Happy accidents?

Proud to say that all the other washes were washed out by the time the water reached the bottom of mine.

I have been thinking about making a backyard refinery using plastics as the feed stock. Diesel is easier to refine and old diesel engines are the most forgiving when it comes to imperfect fuels.

(Extremely small scale mainly for the learning process just incase SHTF and I NEED to scale up)

I took the plunge and got a freeze dryer. I love it.  Though I bought the large one and the batches are larger than I anticipated so I have to aquire a hoard of goodies before I can run a batch.  I am thinking about getting a small one so I can make some ready to eat meals without an industrial kitchen.  Dry powerless storage is a plus, the oxygen absorbers and electricity is a con if SHTF.

Fermentation is probably the funnest method of preservation though.

I have this pot that I acquired somewhere, not sure if it is decorative or meant to be used.  It isn't terracotta, but it is porous.  Maybe I should play with it.

It has been a few years and the carrying capacity of my local range has increased even during drought years. I reckon the results are obvious enough that the normies might notice.

Mystery plant started growing in my lawn, smelled special so I have been mowing around it for about a decade.  I am confident it is an artemisia, but that is a big family and would like to narrow it down, learn the art of propagation, and how to use it. It is currently flowered out so the leaves have pretty much disappeared, did find a good leaf at the base.
