If the OP is asking for a vaporizer that will vape dry sift, I would also love to hear that answer, as well.
I have owned about 50 vapes and I have not found anything that does dry sift well.
The dry herb vapes fail because the dry sift melts and gums everything up.
The rosin/BHO vapes fail because they leave all the ash and, again, clog everything up.
And, it depends (big time) on the quality of the dry sift.
I took some incredible dry sift from fresh frozen and put it in my Longmada Motar (a basic 510 driven quarts cup) and it instantly melted and vaped wonderfully.
However, I put some dirty dry sift with a lot of contaminants in the same Motar and it didn't vape for shit and finally combusted.
The dry sift vapes worked pretty well on the dirty dry sift. However, the good and great quality dry sift melted and fucked up most of them.
One good option I found was to use an iHeat (another 510 driven ceramic convection heater) on top of a Plenty concentrate pad and a water hammer.
Using the hammer keeps the heater upside down so nothing can drip into it. If anything drips, it goes through the pad onto the stem for reclaim. A PITA for sure but it works and give a great hit.
I am pressing dry sift today into rosin just to make it east (and cleaner) to vape.
Smoking dry sift works great but I just have not found the perfect vape for it.
The American Psychiatric Association's standard reference for psychiatry defines over 450 different mental disorders. I suffer from most of them.
Please be understanding if I act a tiny bit unusual at times. Thank you.
