FIELD: physics.
SUBSTANCE: present invention relates to a method for continuous determination of shear viscosity (η) paste-like product to be supplied into spraying nozzle for use in spray drying, wherein continuous determination of shear viscosity (η) paste-like product is carried out in a bypass to a paste-like product flow, supplied to the spray nozzle. In the method for continuous determination of shear viscosity (η) paste-like product in production line continuous determination of shear viscosity (η) paste-like product is carried out in a bypass to paste-like product flow, wherein the bypass comprises a pump, a flow meter, a differential pressure tube and a pulsation damper. At that, the shear viscosity lies in range of 20–1,000 MPa⋅s, shear rate higher than 1000 s-1, and the Reynolds number is below 2,300.
EFFECT: technical result is higher accuracy of continuous determination of shear viscosity (η) of the paste-like product in the production line.
