Abstract:
A method for producing flake-like dried DOG by making DOG containing from 10 to 50% by mass of a liquid go through a continuous melt-drying step of a specified condition and then making it go through, as a next step, a vacuum-drying step of a specified condition or a ventilation-drying step of a specified condition while holding a molten state thereof, to obtain DOG in which the liquid in DOG is reduced to not more than 0.5% by mass (dried DOG), and flaking the obtained dried DOG in a flake production step.
