So glad I stumbled onto this forum.
I've experimented in the past with airbrushing cocoa butter into chocolate molds in the past with unpredictable results - sometimes they came out great sometimes not. I figured it was probably the fact that I had cheap equipment (I had been experimenting with the badger bottom-feed gun hooked up to a can of compressed air).
I recently bought a small compressor on Amazon (gets up to 60 PSI) and a 0.5mm top-feed airbrush gun. I thought this would take me into the big leagues! But...I'm having so much trouble getting the cocoa butter to spray out of the airbrush gun. It's tempered I've made sure that the gun is warm - there are no clogs. I started with a 0.3mm gun and decided I needed a larger aperture; and thus upgraded to the 0.5mm.
Any tips? I've heard some say that you need more pressure (maybe > 60 PSI?) and then I've seen videos where they recommend 30-35PSI.
When I press the button on the airbrush gun, air comes out, but very very little cocoa butter. If I "pump" the trigger, it comes out in little bursts, but not consistently.
