An installation for producing capsules by spraying

A gear pump and a centrifugal spray nozzle were used in the encapsulation unit. 0.8% and 1% sodium alginate were obtained for the encapsulated material. The capsules obtained in a concentration of 1% sodium alginate during the experiment were rounded and homogeneous, soft but stable under physical influence, and had an average diameter of 1,2×10^-3м. To get one kilogram of mk capsules, it is necessary to take V_z=1,404·10^-3 м³ from the volume filled with capsules. This corresponds to the set productivity per hour. Turbulent motion is characterized by continuous mixing of liquid particles. Basically, transverse movements of particles moving longitudinally occur along the flow, the trajectories of which are very complex. Centrifugal nozzles are widely used in modern spray devices, which is explained by the simplicity of their design, reliability and efficiency of spraying. The main difference between a centrifugal nozzle and other types of sprayers is that the liquid passing through it is twisted, that is, it acquires a moment of magnitude relative to the axis of the nozzle. The pressurized liquid is pumped through the inlet channel into the torsion chamber, where it circulates intensively. The technological scheme of the installation is based on the operator's scheme.
