Does anyone know why this happened to me? The mill started to leak something black, maybe some kind of lubricant (for whatever reason they put lubricant into parts that come into direct contact with food).

I used a radiant heater in combination with a thermostat to maintain the temperature of the mixture between 40 and 45 degrees (last photo shows my setup). I don't know whether it's too high temperature that caused the problem, but then how on earth am I supposed to make chocholate in this grinder?

I don't know how I can trust any machine again, I noticed this by accident and it could have happened that I wouldn't have seen this and poisoned myself and everyone whom I gave this chocholate. Can you give me any advice 😭

Thanks a lot...
