Couple ways...Dry ice being easiest.
Another way is:
(Copied+pasted.)
How to: To build the extractor tube you will need a piece of PVC or metal pipe 8-12” long and at least 1” wide and (2) end caps in the same width. For mine I used a 12” long piece of 1 ½” PVC (sch 40) and (2) 1 ½” end caps. I chose PVC because the cost is very low and you can purchase PVC in short lengths. You can also buy extractor tubes already made from several different companies, but they are so easy to make, why not just build one! You just want to make sure it’s large enough to hold approximately 1 ounce of ground up trim. In one end cap drill (1) hole dead center that is just big enough for the butane tip to fit in, and the other end cap drill several smaller holes clustered in the center for the butane to drip out of. I chose to drill 7 small holes in mine. This end cap can be glued on permanently using an epoxy for the material of your tube. The other end cap needs to be removable to fill with trim material. Add a lining of coffee filter to the inside of the bottom cap to catch any loose material before it drips down into your extracted final product. Make sure to wash and rinse all of these parts very thoroughly before use to ensure no drill shavings or dirt end up in your extract. Once they are clean then we are ready to extract!
Using a coffee grinder or chopper, grain your trim down to a uniform size and pack your tube full of trim material (without pressing too hard), then replace the end cap. You will need 2 glass dishes to put under your tube; one to collect the dripping butane extract and another bigger dish that fits your collector dish inside of it. Set this up double-boiler style, with the smaller glass dish inside the larger dish and add hot water to the bottom one to keep the butane dripping from freezing. The butane comes out of the can so cold that it will frost up the receiving dish without hot water and it also help the evaporation process along a little quicker. If you used metal or glass pipe to build your extractor tube you will need to build a stand to hold it vertically when expelling the can, the metal or glass will get too cold to hold in your hand. The stand can be built with any materials you have laying around: scrap wood pieces, 2 eye hooks, some metal wire and duct tape was what I’ve use in the past. Channel your inner MacGyver and see what you can come up with! I used plastic for honey tube so I was able to hold it in hand during the process. A place outdoors with a slight breeze is the best environmental setting to do this in, guaranteeing that the butane fumes are carried up and away but don a pair of safety goggles and leather work gloves for this next part just to err on the side of caution. To begin the extraction process, fit the tip of your butane can into the hole on the top of your tube and press down hard to expel the butane fuel. After the can is empty, step back and let your tube do its work. Within 30-45 seconds you should see the butane drip out the bottom holes and into your collector dish. A few good shakes when the dripping starts to subside will help you get every last little bit of goodness from your tube set up.
