Process equipment for cocoa & chocolate


The installation, type CAO 4000[3]-CHOC IN-LINE, is specially designed for the weighing, mixing and continuous fine grin-ding 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, three ball mills CAO 4000 and a heat exchanger. The first ball mill is pre-refining the mass and the second ball mill fine refining.

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 optimum use of the grinding efficiency.

The capacity of the line is up to 2.000 kg/h when crystal sugar is used as an ingredient. In case of using powdered sugar the capacity is considerably higher.

At the outlet of the second ball mill the mass is collected and used for further processing.

These features result in:

  • Precise management of product temperature
  • Low energy consumption
  • Low maintenance costs
  • Constant product quality
  • Good particle size distribution
  • Minimal manpower required
  • End-fineness can be up to 18 microns

The CAO 4000[3]-CHOC IN-LINE can be supplied with our automatic feeding system, such as feeding screws, lecithin dosing, etc.
