Abstract
Official abstract text for this publication.
The present invention relates to a method of continuously determining the shear viscosity (η) of a product paste to be delivered to a spray nozzle for spray-drying applications wherein the continuous determination of the shear viscosity (η) of the product paste is carried out in a bypass to the product paste stream to the spray nozzle.
First claim
Opening claim text (preview).
1 . Method of continuously determining the shear viscosity of a product paste in a processing line, wherein the continuous determination of the shear viscosity of the product paste is carried out in a bypass to the product paste stream, the bypass comprising a pump, a flow meter, a differential pressure tube and a pulsation damper and wherein the shear viscosity is in a range of 20 to 1000 mPa·s the shear rate is greater than 1000 s −1 and the Reynolds number is less than 2300. 2 . Method according to claim 1 , wherein the shear viscosity of the product paste is determined by the following steps: a) providing a constant feed-flow-rate of the product paste; b) determining the mass flow of the product paste; c) delivering the product paste to a pressure-drop-meter and determining the differential pressure; d) calculating the shear viscosity of the product paste on the basis of the laminar mass flow and the product density determined in step b), as well as the pressure drop determined in step c). 3 . Method according to claim 2 , wherein the calculation in step d) considers also the bypass-mass-flow-rate. 4 . Method according to claim 2 , wherein the determination of the pressure drop in step c) is carried out according to the differential pressure drop method. 5 . Method according to claim 1 , wherein the product paste is to be delivered to a spray nozzle for spray-drying applications, wherein the continuous determination of the shear viscosity (TO) of the product paste is carried out in a bypass to the product paste stream to the spray nozzle.
