  • Method and apparatus for cryogenic crystallization of fats
    Patent number: 4952224
    Abstract: A method and apparatus for converting liquid fats into solid particles for blending with dry feed ingredients comprises spraying atomized liquid fat into the upper portion of the mixing chamber while directing a plurality of fine jets of liquid nitrogen against the liquid fat spray so as to produce solid fat particles which fall into the dry ingredients at the bottom of the mixing chamber. A homogeneous mix free of fat lumps is thereby readily obtained, even at the higher percentages of fat required for some animal feed.
