Process equipment for cocoa & chocolate


The installation, type CAO B3000-CHOC DUO, is specially designed for the weighing, mixing and batch wise fine grinding of chocolate, coatings, compounds and bread spreads.

The line consists of a weighing vessel, specially designed to provide automatic (PLC controlled) weighing and mixing of basic ingredients, a jacketed buffer tank and two ball mills CAO C3000, which are circulating over the mixer.

The ball mills are low speed agitated types, developed for heat and wear sensitive masses. It’s a unique configuration between grinding shaft, grinding tank and grinding media. This leads to an optimal use of the grinding efficiency.

  • Minimal manpower required
