Abstract

Conching is a well-known modern method used in making chocolate, which involves a long process of intense mixing, agitating and aerating of heated liquid chocolate. However, this conching method has not been tested yet in the dodol production. The work presented in this paper concerns the development of an experimental rig for dodol conching process. Analysis of the range of conching displacement is made based on two parameters changes. Firstly, the height of roller from the centre point of the rotational driving disc. Secondly, the distance between the attachment joint of roller arm and rotational driving disc. The speed of conching process is controlled by DC motor based on Pulse-width-modulation (PWM) technique. The results have shown the desired speed response can be controlled accordingly through the adjustment of the input signal.
