hey everyone.I hope you can help me, I have a small business and make chai tea. I need to coarsely grind up 5-6 kilos of cassia bark every month. Its getting tiring and long grind it in the blender. I think even the motor will eventually blow on the Kenwood blender if I dont change it soon. I've really looked into this, but I have not found any advise.. the sticks I get a very thick and long, but i break them by hand and jump them on top of the box to break it down before I get to put it in the blender... I also ground up 5-6 kilos of cardamom pods, cloves and star anise as well.. I would love to know how to grind in down these spices into small chips quickly and easily, without all the dust that flies everywhere from my method.. Im not a professional cook, I have googled but can't find the right kind of grinder.. Not sure what im even supposed to be looking for.. Do you have any suggestions that would help?
