A continuous stream of chocolate mass is dosed with lecithin or similar emulsifiers by means of an electronically controlled dosing pump. The throughput or the weight rate of the flow of the chocolate mass is detected by a weighing device and the amount of the emulsifier to be added is adjusted to the changes of the throughput. The percentage of the emulsifier is preselected. The dosing time of each charge of the chocolate mass is determined as a first time interval from the detected weight rate of flow. During the dosing of a charge, a second time interval which is a predetermined fraction of the first time interval, is determined for the next charge during the dosing of a preceding charge. A control unit actuates a time counter for determining the first time interval whose value is stored in an intermediate storage. An operation counter determines the second time intervals and activates a control unit for the emulsifier dosing pump. |
