Summary, Etc. Note: |
Abstract: A stable, free-flowing dried soluble could be included in mixed farm-animal feeds by many manufacturers who do not have the equipment to use the condensed solubles containing 50-percent solids. Dried solubles were prepared by means of a small drum dryer from 32 sampes of typical condensed menhaden solubles obtained from plants along the coasts of the Middle and South Atlantic and the Gulf of Mexico. About 3/5 of all the samples tested were readily dried and gave dry products that would be satisfactory if handled and packaged so as to prevent absorption of atmospheric moisture. |

Abstract: A number of chemical and physical properties were determined both for the condensed solubles and for the resultant dry products. Ten properties, or drying characteristics, for the solubles or the dried product were used to calculate a "Suitability Factor" that would permit estimating the value of a particular sample of condensed solubles to produce a satisfactory dry product. The correlation of certain properties of the condensed solubles to characteristics of the related dry products will be presented in a later report. |

Abstract: Improvements in certain drying characteristics were obtained with some difficult-to-dry samples of condensed solubles by the use of small amounts of additives. However, when added to amounts of 10 percent or less, none of the additives entirely prevented such features as excessive hygroscopicity, hot-plasticity, oil separation, and drum adhesion, which result in an unsatisfactory dry product. |
