The invention discloses a
lepidium meyenii walp temperature-varied
drying method and belongs to the technical field of preliminary
processing of agricultural products. The method mainly comprises the following steps of cleaning and washing fresh
lepidium meyenii walp, draining off water residues on the
lepidium meyenii walp, and conducting temperature-varied
drying on the
lepidium meyenii walp at the
room temperature. Compared with a traditional airing method, according to the method, hot-
air drying equipment is used, the process that the temperature is raised gradually from the low temperature to the high temperature at a variable-speed mode is adopted,
lepidium meyenii walp
moisture is prevented from being lost rapidly,
shape change is reduced, the color and lustre are maintained, under the condition that nutritional ingredients are not lost, the
lepidium meyenii walp
drying time is shortened by over 20 days, the drying efficiency is remarkably improved, and meanwhile defects that by means of a traditional solarization method, manpower is consumed, the occupied area is large, and
pollution is prone to occurring are avoided.
