The invention relates to a super-high-efficiency lipid hydrolysis reactor which comprises a raw material lipid storage tank, a water storage tank, a steam inlet tube, a gas-liquid ejection mixer, an inner cylinder, an outer cylinder, a glycerinum flash tank, a fatty acid flash tank, a scraper evaporator, a glycerinum rectifying column and a fatty acid rectifying tower. A high-temperature high-pressure steam power source is adopted, and a gas-liquid ejection mixer is taken as a compulsive material mixing, mass transfer and reaction key component. The invention further provides a reaction process of the reactor. By adopting the reactor, the phase boundary of lipid and water is greatly increased, so that the reaction time of hydrolysis is greatly shortened, on the basis, the reaction temperature and the pressure can be appropriately reduced, so that the energy consumption and the operation cost are reduced, and meanwhile the security coefficient of equipment is increased; the reactor can be used in the hydrolysis process of lipid consisting of different fatty acids, the different fatty acids and glycerinum water can be efficiently separated after the hydrolysis is completed, and a corresponding fatty acid product and a glycerinum product are obtained.
