So, I'm making a lot of rice flour these days.... both white and brown. I'm wondering how long I can grind for? I like to do a kilo of each (250g at a time, speed 9, 2 minutes) so I can just fill my containers, but it creates a lot of heat in the bowl etc. Is there a limit to how much grinding/milling should be done in one session?
Also, if I finish the session with 2 trays of ice, should that keep my blades sharp?
