Poormans Short Path Distillation:
At some point in your concentrate making career you will have the need to ramp up your distillation capacity. I've built several Poormans distillers over the years but my latest configuration, pictured here, works the best, so figured I'd share it.
Distillation, as you know, is the process of separating a solution into its component parts, called fractions, based on heat. The idea being the lighter weight molecules will rise and leave the solution as steam at a lower temperature than the heavier molecules.
The basic components consist is a vessel to hold the charge solution to be heated and separated, the heating device called a mantel, the cooling tube and the collection vessel. More elaborate systems will have a chiller casing around the cooling tube to keep it cold and, perhaps, a vacuum ability. For our needs, these can be eliminated.
The system here consists of a simple rice cooker to act as the heating mantel, a Pyrex heat resistant
coffee carafe for the heating vessel, a rubber stopper fitted to the carafe opening and a section of 1/4" copper tubing as the cooling tube. I used a liquor bottle as the collection vessel. Both the rice cooker and the carafe I sourced from Goodwill for around $16. The stopper I found on Ebay for $5. The cooper tubing from the hardware store.
I fill the rice cooker with glycerol to act as a heat transfer agent between the cooker and the carafe. The heat can be regulated using an autotransformer, not shown.
Right now, using this in my garage, the ambient temperature is so low it is not necessary to cool the collection vessel. If the temperature is above, say, 50 degrees F where you are distilling it is advisable to set the collection vessel in a bowl of ice water. This will act as a catalyst to "draw" the heated vapors over from the charge vessel that much faster.
