摘要：
A method of controlling the spray droplet size of a spray nozzle apparatus, in particular for the manufacturing of food powders, delivered to the spray nozzle comprises the following steps: a) providing a paste of a product to be sprayed by a spray nozzle； b) continuously determining the shear viscosity (η) of the product paste delivered to the spray nozzle； c) determining the mass flow rate (Qrn) of the product paste delivered to the spray nozzle； d) determining the static pressure (P) of the product paste delivered to the spray nozzle； e) determining the density (p) of the product paste delivered to the spray nozzle； f) delivering the data obtained in steps b) to e) to a control device comprising a computer and a memory； g) calculating control data for adjusting the spray nozzle on the basis of the data obtained in steps b) to e) and on nozzle geometry parameters stored in the memory； h) sending the control data as control signals to a control means of the spray nozzle and adjusting the spray nozzle accordingly.
