The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Provided is a urea granulating method by which urea particles having stable quality can be obtained. The present invention relates to a urea granulating method using a urea granulation tower having: an exhaust port provided at the top thereof; a molten urea spray section; a plurality of air intake ports; and a recovery section for granulated urea particles. In the urea granulation tower, the molten urea spray section is positioned at the upper side of the urea granulation tower, the plurality of air intake ports are positioned at the lower side of the urea granulation tower, the recovery section is positioned at the bottom of the tower below the air intake ports, and the plurality of air intake ports are arranged at intervals in the circumferential direction. The urea granulating method according to the present invention comprises a step for forming urea particles by spraying molten urea inside the urea granulation tower and cooling and solidifying the molten urea by taking in, from the air intake ports, air at the ambient temperature of the urea granulation tower from the bottom to the top, wherein the inside of the urea granulation tower is heated by supplying, in addition to the air at the ambient temperature, heated air at a temperature higher than the ambient temperature."
The patent application was internationally filed on Mar. 28, 2024, under International application No.PCT/JP2024/012599.
