Scaling of the device with opposite twirled streams the inert carrier for drying an agar agar

Kutsakova V. E., Namliyev Yu.V., Panina T.S., Fedorova A.M.

A drying unit with the swirl jets of inert supports is considered. It is designed for drying of agar-agar. The conditions for the scaling of internal nodes of the machine are considered. The relationship between the overall dimensions of the unit and the lower nozzles orientation angle is given. The dependence of the device diameter on the coolant flow, the height of the upper nozzles and the terminal velocity of inert particles is given.It is shown thatfor the enforcement of constant speed of the particles in the upper section of the unit height of the upper nozzle should decrease with an increase in the diameter of the unit. Moreover, for the heavier particles should be selected unit with a smaller radius at constant all other design parameters.The correlation between the calculated and experimental data is given.
