A device for moulding foodstuff masses comprises: one or more moulds (14) provided with sockets (16) which define pouring cavities； inserts (22) made of thermally conductive material associated, in a relationship of heat exchange, with the pouring cavities (16)； and thermal-conditioning units (24), such as Peltier cells, associated to the inserts made of thermally conductive material (2). <；??>；There is present a control unit (34) for generating signals for control of the thermal-conditioning units (24) so as to provide cycles of thermal treatment of the material undergoing selectively pre-determined pouring. <；??>；A preferential application is in the sector of the confectionery industry. <；IMAGE>；
