The invention relates to an enzymolysis-liquid nitrogen freezing husking method for flaxseeds and husking equipment for the flaxseeds. The equipment includes a screening unit, an enzymolysis tank, anair drying unit, a liquid nitrogen freezing chamber and a rotary impactor connected in sequence, and the screening unit, the enzymolysis tank, the air drying unit, the liquid nitrogen freezing chamberand the rotary impactor are connected to a controller. Before the flaxseeds enter the rotary impactor, the flaxseeds are subjected to enzymolysis and liquid nitrogen freezing treatment, composite cellulose is used for enzymolysis of flaxseed gum at flaxseed husks, so that part of the cellulose in the flaxseed husks is decomposed, and the husk structure is loosened, after a short period of liquidnitrogen freezing treatment, the flaxseed husks become brittle, and finally the flaxseeds enter the rotary impactor, at the time, the flaxseed husks are fragile, but flaxseed kernels are not subject to ultra-low temperature fre
