Anybody still reading this thread?
I make my own bokashi bran, using bulk wheat bran or rice hulls as the carbon source.
Works great, but I am puzzled about how to dry it. If the microbes are sensitive to heat and prefer an anaerobic environment, that seems to eliminate heat and air as drying methods, and without heat and air... how am I supposed to dry it? Yet you're not supposed to keep undried stuff for more than a couple weeks, right?
Thus far I have just been using the wet stuff in our bucket, and using way more than is necessary in order to exhaust my supply before a few weeks elapses.
Love EM-1 and Bokashi, but the fact that it's SEKRIT PROPRIETARY TECHNOLOGY makes it a PITA at times.
Get yourself a tarp maybe 8 x 8 and spread it out on a nice sunny day. A full day in the sun is plenty of dry time.
rrogEveryone dries it and it all works, so after a month of fermenting I figure the bacteria is safely inside the bran, hidden from UV.
I've been to several Bokashi sites and they all just lay it out to dry.
Isn't sunlight anti-microbial? And isn't fresh air not the optimal environment for anaerobic microbes? That was the point of my initial post, if it was unclear. I know *how* to dry things in the sun, but since both sun and air seem inhospitable to the microbial life I'm trying to cultivate on the bokashi bran, I am wondering how else to dry it.
