Panning
The panning process begins by preheating the drum and adding the centers to be coated. The centers are then coated with a thin layer of chocolate or sugar coating, which is allowed to dry before adding additional layers. This process is repeated multiple times until the desired thickness is achieved. The drum is rotated at a controlled speed to ...
