Chocolate Refining


  • Grinding by means of compression and shearing
  • Two-stage refining process consist of one pre refiner and one or several final refiners in sequence
  • Primary particle size reduction by means of pre refiner followed by secondary particle size reduction by means of final refiner


  • Targeted particle size with a narrow particle size distribution to generate mouth feel and simplify flow property development
  • Coat new arise sugar surfaces with cocoa and milk flavors to aromatize sugar and avoid moister absorption
  • Constant specific throughput for highest productivity


  • Use of coarse granulated sugar 0.5 – 2 mm (recommended, powder sugar possible)
  • Absorbing ingredients variation
