NOVELTY - Device for producing green coal of agricultural use from agricultural organic materials includes a receptacle (5) to receive organic materials; an enclosure (1) containing the receptacle and delimiting an embedded blank around the receptacle; a heating system of the embedded blank; and a system of rotary mixing configured to brew organic materials placed in the receptacle, the system of rotary mixing includes multiple fixed blades (15) and multiple mobile blades (14a, 14b) in rotation compared to receptacle. The fixed blades is divided into at least two stages of fixed blades.    USE - Used as a device for producing green coal of agricultural use from agricultural organic materials.    ADVANTAGE - The device makes it possible to produce substantial quantities of coal of agricultural use in a quick manner, improves the effectiveness of mixing imposed on organic materials during the phase of carbonization, can realize water spraying at the end of manufacturing so as to cool manufactured coal of agricultural use quickly and to allow more quickly its evacuation by the pipe.    DETAILED DESCRIPTION - Device for producing green coal of agricultural use from agricultural organic materials includes a receptacle (5) to receive organic materials; an enclosure (1) containing the receptacle and delimiting an embedded blank around the receptacle; a heating system of the embedded blank; and a system of rotary mixing configured to brew organic materials placed in the receptacle, where the system of rotary mixing includes multiple fixed blades (15) compared to receptacle and multiple mobile blades (14a, 14b) in rotation compared to receptacle. The fixed blades is divided into at least two stages of fixed blades along the axis of rotation, the multiple mobile blades is divided into at least two stages of mobile blades along the axis of rotation. The fixed stages of blades and the mobile stages of blades alternate along the axis of rotation.
