do you know if the refining process could be made with a colloid mill?
We are in Venezuela at the Caracas historial centre. We have a chocolaterie and we are working to build a small factory to produce (milk & bitter) chocolate tablets and "bombones". This factory will be seen for the visitors of the Caracas historical centre.
They can be used to grind nibs into liquor quite effectively. I've not tried grinding sugar/milk with the nibs, but it's technically feasible. Heat build up is going to be your enemy, so you'll need to find a way to take it out. Also, your paste is going to have to be fluid enough to flow through the grinding chamber, which could very well prove to be your limiting factor.
We are going to refine cocoa liquor with sugar/milk. Previosly we had mix this products.
The first trial is going to be in a month. I am going to try to upload some photos and a report.
Omar - does the grinding apparatus of your machine - is it a conical shaped piece that has the texture of rough sandpaper at the center of your unit with a cap that sits over it, or does the center of the unit have a pair of 'blades' that throw the material towards the outside walls, where the metal is a series of very roughly serrated edges?
well ... I really dont know. Its not ready yet and its been made in Maracaibo. I live in Caracas, 700 km far away.
I am going to post the answer when I have it
