Dewaxing shatter

blow colder & suck harder

or use better input material.

here’s one opinion on how to blow colder…

@Otscc

1. Start by chilling your material columns. With open sleeved jackets a dry ice/ 99% isopropyl solution will reach -110, and with closed jackets liquid nitrogen is appropriate. Chill the solvent tank at this time as well.
2. Once you have reached and are holding desired temp while also maintaining vacuum it’s time to prime the system. We do this by pushing warm vapors from another solvent tank into the system.
3. Turn on your recovery pump and open recovery port on your cold tank, allow it to build a bit of pressure. While doing this, remove the cold solvent tank from its chilling bath, place it on your refrigerant scale, then open the liquid port and begin flushing. I do a 10:1 solvent to material.
4. Once the solvent has pushed through the material column I let the solute run through my buchner vessel (purchased from open source Steel). I put pro pak distillation packing on top and between the filters to prevent clogging. Freeze with dry ice and iso/etoh for at least one hour. I’ve had clients get good results without dewaxing.
5. After allotted time, I open the next valve and allow it to run through the filters into the collection vessel. I recover at 65° to preserve the terps.

sucking harder is left as an exercise for the reader…and might also qualify as sucking longer.
