This study aims to design a melanger machine, which is an alternative machine for processing semi- finished chocolate into ready-to-consume chocolate. The chocolate processing itself is divided into 3 processes, namely the mixing process, the refining process and the conching process. The melangeur machine is an alternative machine that can be used for   all three processes. However, the price offered is quite expensive for a capacity that is not too large and it is rare to find similar products made in Indonesia. There are 2 different types of machines used for benchmarking, namely the Premier Wonder Chocolate Melanger Refiner and Elektra 11 Chocolate Melanger. The two machines will be compared in terms of specifications, advantages and disadvantages. The method used in this research is the benchmarking method, the reverse engineering method and the engineering design method. The final result of this engine modification design has increased the capacity of the chocolate by 67%, namely a total of 5 L with the same quality as the existing machines
