The utility model relates to the technical field of desublimation crystallization equipment in chemical production, and discloses desublimation crystallization equipment for producing large-particle crystals, which comprises a body, the body comprises a body upper part for connecting a hot gas input structure and performing condensation crystallization, a body middle part for crystal growth and a body lower part for collecting discharged crystal particles; the inner diameter of the upper part of the body is smaller than that of the middle part of the body; a gas distributor matched with the hot gas input structure is arranged at the upper part of the body; a cold air input structure is arranged in the middle of the body, and a discharge structure is arranged on the lower portion of the body. By optimizing and improving the structure of the desublimation crystallization equipment, hot air enters the equipment, is desublimated by two sections of cold air environments at the upper part and the middle part of the
