摘要
A process for the preparation of neem oil water emulsion coated urea prills capable of being integrated at fertilizer plants for a large scale and continuous coating process; comprising the steps of :- a) mixing neem oil & emulsifier in the ratio of 4:1 in a concentrate preparation tank by recirculating the contents with the help of a pump at 4 Kg/cm2 for 15-25 minutes to get the neem oil emulsified concentrate ; b) mixing a predetermined amount of concentrate of step (a) through ejector nozzles in a span of 30 - 40 minutes to a predetermined quantity of water in the emulsion preparation tank, which is re circulated & agitated with the help of a pump at 3- 4 Kg/cm2 pressure through 2 nos.fanjet nozzles, when the neem oil water emulsion thus formed is led through 2 nos. acoustic nozzles where micronization of the emulsion is done to obtain a stable micronized neem oil water emulsion ; and . c coating neem oil water emulsion on urea prills with the help of a gear pump at a pressure of 3- 7 Kg /cm2 when the neem oil water emulsion is drawn from the emulsion storage tank & passed through 2 nos. of fan jet nozzles and full cone nozzles to spray on the urea curtain, such that it covers a maximum area on the urea curtain to get the
