The invention relates to an apparatus(1) for decocting ingredients (2) in a solvent (3) said apparatus comprising: a first container (4) for containing the solvent a pipe (5) connecting an output (O1) of said first container to an input (I1) of said first container a pump (6) placed in series with said pipe for circulating the solvent from said output (O1) to said input (I1) a second container (7) for containing the ingredients said second container being placed in series with said pipe such that the solvent circulating in the pipe can circulate in between the ingredients a wave generator (8) placed next to said second container for generating a field of waves (FW) towards the ingredients. The dynamic circulation of the solvent in combination with the application of a field of waves towards the ingredients allows accelerating the extraction of the compounds in the ingredients and leads to improved extraction efficiency.
