  • Patent number: 5657687
    Abstract: A conche for producing chocolate compound consists of a conche container (10) with a main chamber (12) and subsidiary chambers (13, 14). Mixing vanes (22, 23 and 30, 31) are disposed therein on central shafts (19, 20, 21) in order to intimately mix the components fed in from above. In order to improve the mixing effect, additional mixing tools in the form of mixing worms (37, 38) are disposed in the lower part of the conche container (10), in particular in the main chamber (12). Stripping means (24, 25) moved along a cylindrical container wall (15) are supported solely in the region of a central transverse plane on a main shaft (19) in the main chamber (12). The main shaft (19) is provided with a clear cross-sectional thickening (28) which at the same time fills a dead space in the conche container (10).

  • Patent number: 5320427
    Abstract: In the continuous conching of chocolate mass in a conche (10) it is important to ensure essentially constant contents of the conche (10). For this purpose, the infeed of starting material and/or the discharge of the conched chocolate mass is monitored, namely measured, especially by means of weighing. In response to the measurement results, the infeed or the discharge is controlled, especially by means of altering the conveying capacity of a compulsory conveyor (screw conveyor 21) for discharging the conched mass. The conched chocolate mass is dry, i.e. it contains neither lecithin nor cocoa butter. Lecithin is added in the region of the screw conveyor (21) which is followed by a mixing device (22).
