The RUMBO stone-on-stone grinder for the craft chocolate maker. 


The Rumbo stone mill grinder was designed for craft chocolate makers committed to traditional stone-on-stone grinding but improves the process by providing more precise control over the parameters of the chocolate-making process. 

Unlike other stone grinder systems where the base or the working bowl rotates, in the Rumbo the millstones turn operated by a direct drive motor without gears or belts, and includes forced hot air as a standard feature. This enables the solid granite base and the solid granite grinding stones to be heated before a batch is started which releases the cocoa butter from the nibs more effectively than from a cold start. Forced air is adjustable, from ambient air up to 75°C and can remain on during the complete grinding process as desired, which leads to shorter processing times.
