A method and apparatus for continuous manufacture of viscous food products such as process cheese-type products wherein a formulation is continuously pumped through a cooker assembly comprising an elongated tube or housing having a rotor which shears the formulation as it travels longitudinally through the tube while imparting little or no axial motion to the formulation as a result of contact with the rotor. The temperature of the formulation as it proceeds through the cooker assembly may be in the range of about 150° F. to about 250° F., and the residence time of the formulation may be between about 30 seconds and about 8 minutes. The formulation may be subjected to shear of between 10 and 1,000 sec-1 with an absolute viscosity µ of between about 20 and 50 poise, while the rotor is operated at a rotational velocity of between about 10 rpm and 800 rpm.
Cette invention concerne un procédé et un appareil de fabrication en continu de produits alimentaires visqueux tels que des préparations de fromage fondu. La matière première est pompée en continu à travers un cuiseur en forme de tube ou d'enceinte allongé renfermant un rotor qui cisaille la matière à mesure qu'elle progresse dans le tube ou l'enceinte précités en exerçant une poussée axiale faible ou nulle sur celle-ci. La température de la matière première peut se situer entre environ 150 degrés Celsius et environ 250 degrés Celsius à l'intérieur du cuiseur et le temps de séjour de la matière première dans celui-ci, entre environ 30 secondes et 8 minutes. La force de cisaillement appliquée à la matière première dont la viscosité absolue .mu se situe entre environ 20 et 50 poises peut atteindre entre 10 et 1000 Pa.sec-1, le rotor tournant à un régime compris entre environ 10 et 800 tr/min.
