1,270,976. Treating proteinaceous materials. INTERNATIONAL BASIC ECONOMY CORP. 24 April, 1969, No. 21083/69. Heading A2D. A process for removing moisture from particles of heat sensitive solid proteinaceous material of about 1/4 inch particle size comprises mixing said particles with liquid oil or fat having a boiling point higher than water to form a first fluidized material, mixing this with 2-20 times its weight of a second fluidized material heated to a first temperature of not above 250‹F, said second material being a dehydrated form of the first, to form a mixture, and lowering the temperature of the dehydrated material 2-10‹F to a second temperature and after a dwell time of 3-7 secs applying a reduced pressure of 1-10 mm Hg wts to the mixture of 0-50 secs to provide a pressure differential between the normal boiling point of water at said reduced pressure and the second temperature of at least 20‹F, whereby moisture within the particles is explosively rebased to form an expanded porous dehydrated oily material. The process is applicable to such proteinaceous materials as animal tissue (including poultry and fish offal), vegetable materials, i.e. peanut and cotton seed meats and dried blood. Suitable oils are peanut oil, cottonseed oil and animal oil. |
