Abstract
A low cost, high capacity method for making starch-NPN liquid feed supplements is provided wherein a substantially NPN-free slurry containing water and a starch source is treated under high temperatures and pressures to gelatinize the starch component. After gelatinization, an NPN substance such as urea is added and thoroughly mixed with the slurry to produce a final feed. The cooking step may be advantageously performed indirectly using a tube and shell heat exchanger, or alternatively in a direct steam injection jet cooker. A wide variety of NPN substances can be employed in the supplements hereof, along with a large number of starch sources such as grains or industrial wastes. In addition, the liquid supplements can be modified either before or after processing by adding energy sources such as molasses thereto.
