Abstract: A device for working candy dough subsequent to delivery from a baking oven and prior to discharge for molding and cutting comprising effecting continuous travel of said mass under a pressure of between 500 and 700 mm Hg. and in an environment substantially free of air, steam, or gas, while continuously kneading and cooling the mass with concurrent intermixing of additives and optional introduction of filler. The invention also comprehends a machine having parallel rotors within intersecting cylindrical containers, there being heat transfer means surrounding said containers with an inlet at one end for the mass to be worked and an outlet at the other end for the mass subsequent to working. An intermediate feed duct is provided for introducing additives into the mass and a discharge head is provided at the outlet end with a filler device being optionally mounted within said discharge head. The discharge head may have more than one nozzle so as to accommodate a plurality of production lines simultaneously.
