thanks for all the suggestions, I was looking into a Robo Coupe but the prices are quite high so I will inquire into the others. I suppose my budget would be $1000- 1500. I am looking to grind around 25 kg at a time, but this could increase over time- I don't currently know how much I will be needing to make in an hour- this is a new product and I haven't launched it just yet but I have decided that a continuous feed method would be preferred.
I am also curious about what folks tend to use for chopping blocks of cacao butter? I was suggested to use a rotary hammer with a chisel bit.

@Viva Cacao - what amounts do you need to process in an hour or overall in a shift, and do you have a budget? That will help everyone suggest a piece of equipment that is scaled to your needs and your finances.

Packint also makes a machine for this that I've heard great things about.

One of the things we have in our shop is a 20qt Hobart mixer with a shredder/grater attachment. As long as you are careful on feed rate to keep it from getting too hot and melting the chocolate, something like that should grind the chocolate down in a hurry.

Hi Viva - talk to the fine folks over at Urschel milling. I've used their products for decades for the very purpose you're indicating. They'll have a rotary milling head that'll work just fine.
