A machine for the production of ice-cream in doses, of the type comprising a mixer (5) of the starting food preparation, a whisking machine (6) and a cooling system (17,25) of said whisking machine, a thermal bridge also being envisaged between said whisking machine (6) and said mixer (5), so as to cool the latter to a sufficiently low temperature for preventing bacterial proliferation in the food preparation residues present inside the same.With respect to traditional machines for the production of ice-cream in doses, that of the invention offers the advantage of ensuring the best conditions of genuineness of the final food product, without the risk of bacterial contamination coming from the mixing chamber.
