Device for the working of candy dough hard and/or filled candies and a device for carrying out this proceeding

A machine for the manufacture of a candy mass comprising:

• means defining at least two circular cross section cylindrical containers, said containers being longitudinally connected along lines formed on the surface thereof between the end points of a cord defined by the intersection of the circumferences of said containers thereby limiting the area of the cross sections thereof and cooperating to form a continuous enclosed chamber sealed from the environment therearound;
• an elongated rotor provided within each container, said rotors being in axially parallel relationship;
• means for effecting rotation of said rotors about the respective longitudinal axes thereof;
• means defining an inlet passageway for said candy mass into said chamber located adjacent one end of said chamber;
• means defining an outlet passageway for said candy mass located adjacent the end of said chamber opposite said one end;
• a first screw feeder on each of said rotors on respective end portions of said rotors adjacent said one end of said chamber;
• a second screw feeder on each of said rotors located on the end portion of the respective rotors adjacent said opposite end of said chamber;
• a series of kneading blades provided on each rotor and being located on a respective rotor intermediate said first and second screw feeders;
• means defining a shell surrounding said container and being disposed radially outwardly therefrom to create an intervening volume;
• means sectionalizing said volume longitudinally to provide separate heat transfer compartments within said volume of preselected longitudinal extent;
• a fluid inlet and a fluid outlet being provided for each of said compartments;
• conduit means communicating between a candy mass additive source and said chamber and entering said chamber at a point contiguous with said series of kneading blades for introducing additives into said candy mass.
