SPHERIC GRANULE PRODUCTION TECHNIQUE Russian patent published in 1995 - IPC

FIELD: chemistry, agriculture. SUBSTANCE: granules are obtained by dispersing the jet of melt as a result of its regular disturbance. For this purpose a laminar jet is formed. Excitation system 3 is used for disturbing the jet and making it turn into equal size drops. The optimal temperature for cooling in heat exchange chamber 5 is set up by temperature regulator 6. Granules obtained are gathered in separator container 7. After reaching the steady state of generation, the jet speed and the cooling medium temperature are stabilized. The length of trajectory of granules is calculated by the following formula: l > w(τ₁+τ₂), where w - speed of granules, τ₁ crystallization time, τ₂ time taken by granules to be cooled to crystallization temperature 0.5 T. EFFECT: higher efficiency and reliability. 3 dwg, 1 tbl
