The production of graft crystals for use in seeding sugar boiling brines is achieved by means of adding milled sugar of a grain size of 5-20 micrometer to a sugar solution with a supersaturation number of 1.12-1.20 and a volume of 1.8-2.2% of the final volume, homogenization of the mixture by means of a circulation pump and control of the crystallization by maintaining the pressure in the crystallization unit such that the liquid evaporates and the temperature decreasing maintaining the supersaturation number in the range of 1.12-1.20.
