Abstract

The winnowing of cocoa beans is realized by the three basic mechanical operations of crushing, sieving, and sifting. At August Storck KG, different plants are used for the winnowing process. In the following paper, two plants are compared with regard to the procedural processes, and the respective advantages and disadvantages are analyzed and explained. The success of the winnowing plants is determined by two parameters: The shell content in the product stream is used to evaluate quality, and the nib content in the shell stream allows conclusions about economic efficiency.
