The invention relates to a vacuum freeze drying orange membrane peeling technology. The vacuum freeze drying orange membrane peeling technology comprises the steps of orange grading, blanching peel removing, sectioning, enzymolysis membrane removing, sterilizing and lastly vacuum freeze drying. The step of vacuum freeze drying sequentially comprises the steps of single freezing, secondary disc laying, quick freezing and drying, wherein according to the single freezing, cleaned orange segments are arranged at the temperature equal to or lower than -18 EDC C for quick freezing for 1 to 1.5 hours, and the temperature of the materials is maintained between -5 DEG C to -10 DEG C; according to the secondary disc laying, disc laying is carried out on the single frozen orange segments in an operation chamber at the low temperature equal to or lower than -5 DEG C, and evenness and the consistence of the thickness of disc laying are ensured; then according to quick freezing, the condition that fast freezing is carried out for 4 hours at the temperature equal to or lower than 35 DEG C serves as the quick freezing condition; then, quick frozen oranges are arranged in a vacuum drying furnace, heating and heat preservation are carried out by steps, the temperature of the materials is equal to or lower than 60 DEG C, and the vacuum degree is equal to or lower than 60 Pa; heating is finished, cooling is carried out, and then the orange segments are sorted, detected and packed.
