1. A method for drying plant-derived biomass, said method comprising:
(a) a step of grinding plant-derived biomass,
(b) a step of treating the ground product of biomass in oil at 120-300° C. under a pressure which is higher than the vapor
pressure of said oil at said temperature, and
(c) a step of drying the ground product of biomass at 120-200° C.,
with the sequence of steps (b) and (c) being arbitrary.
