1. Put 500 g of the material into a mixmaster-type mixer. (Be sure the material is at or above room temperature.) Mix at moderate speed. 2. Add 100 g of hot (170-180'F) 30% sol'n. of Swift's Technical Protein Colloid 3. Continue mixing until the mass starts to cool and beads or pellets begin to form. As mixing continues in the orbital beater, the pellets or beads become smaller. After about 10 min, approximately 50% are in the 40-60 mesh range. Do not over mix, as prolonged mixing will break up the formed prills or beads. 4. Screen to preselected size. Rate of water solubility may be reduced by spraying the beaded or pelleted material with formalin.
