The invention provides a method for continuously preparing glycine. The method comprises the steps that hydroxyacetonitrile is synthesized with an ammonia source and a carbon source in a tubular reactor, and an obtained solution is concentrated to obtain a concentrated solution; then the concentrated solution is fed into kettle type series reactors for a hydrolysis reaction to obtain a glycine-containing solution; and the glycine-containing solution is refined to obtain refined glycine. The method adopts a device composed of the tubular packing reactor and the kettle type series reactors to carry out hydantoin synthesis and the hydrolysis reaction, thereby achieving the purpose of continuous production; and meanwhile, a distillation device is added before the hydrolysis reaction, and the mass concentration of a hydantoin aqueous solution is increased, so that in the same glycine yield, the kettle type series reactors are reduced, the volume of the kettle type reactors is reduced, the reaction time is shortened, and the purpose of the continuous production is well achieved.
