Had been struggling with this myself. I finally found a way that works well. DynaVap with some hemp fiber works great for some harder hash, the soft stuff you can rosin press. You can check my profile for writeups on this if you are interested.

However I think heating it and crumbling it would achieve similar results. But the dynavap you can go a bit passed the click, like 2-4 seconds is great for hash.
