chiller to an average particle size of about 40 mesh the tempered air flow into the apparatus was at 57 u00b0 f and was discharged at 92 u00b0 f the beads of fat were discharged at a bulk temperature of 86 u00b0 f the discharged particulates then were admitted to a fluidized bed unit which utilized supporting cooling air admitted at about 50 u00b0 56 u00b0 f 45 relative humidity at 72 u00b0 f and discharged at about 67 u00b0 68 u00b0 f the particulates remained in the bed for an average residence time of about 15 minutes and were withdrawn from the bed at an average bulk temperature of about 77 u00b0 80 u00b0 f the product fatty particulates were fully tempered and could be packaged immediately a batch of the product fatty particulates of example 1 and a substantially identical batch of fatty particulates which were formed in the same spray chiller but not treated in the fluidized bed were packaged and their resistance to agglomeration compared each of the two batches were packaged in 200 pound drums and stored at room temperature about 72 u00b0 f and 45 relative humidity the drums also were stored upside down so that the samples taken were equivalently from the bottom of each drum the following table shows the results of the storage stability tests for the untreated control particulates and the treated particulates of.
