The invention relates to a low-temperature desolventizing process for soybean meal. The process comprises the following steps in sequence: (1)uniformly contacting wet meal with high solvent content of 30 percent at 50 DEG C with overheating solvent vapor at 150-160 DEG C to perform heat exchange in the upper layer of a flash desolventizing section to obtain meal with low solvent content of less than 15 percent; (2) allowing the meal with low solvent content to enter the lower layer of the flash desolventizing section to continue uniform contacting with the overheating solvent vapor to perform heat exchange and reduce the solvent content of the flash desolventizing meal to less than 1 percent, and rising temperature to 80-85 DEG C to obtain medium-temperature meal; (3) allowing the medium-temperature meal to downwards enter a vacuum desolventizing section which is a -2000--3000 water column, performing indirect heat exchange with a steam heating interlayer layer by layer during flowing downwards, spraying overheating steam into the lower part of the vacuum desolventizing section to perform short steam stripping and reduce the solvent concentration of the soybean meal to be less than 1000 ppm, so as to obtain desolventizing meal at 60-65 DEG C; and (4) allowing the desolventizing meal to downwards enter a drying and cooling layer, performing drying and cooling with cold air to cool the desolventizing meal to normal temperature with a moisture content of 8 percent, and finally discharging the dried meal as a finished product. The process has the advantages of high yield, high production efficiency and low energy consumption.
