NOVELTY - Static aerobic fermentation drying tower comprises single-face hollow wall (1), double-face hollow wall (2), ventilation units (16), fermentation drying chamber (3), ventilation horizontal pipes (4), ventilation vertical pipes (5), fermentation material (8), chimney (7), reflux wind pipe (9), fan (10), reflux wind passageway (11), and temperature sensor (13).    USE - The device is useful for agricultural organic waste resource utilization and environmental protection.    ADVANTAGE - The device solves problem that bare production in the present compost technology is inclined to cause secondary pollution, low resource recycling rate and large volume of organic material inconvenient to carry. The fermentation tower and the construction of the tower body are combined, which is durable and saves investment and can be applied to routine loading machine. It has high efficiency and low production cost. The product is superior organic fertilizer and the added microbes with specific function are also organic fertilizer.    DETAILED DESCRIPTION - Static aerobic fermentation drying tower, where the fermentation tower is of cuboid multi-cell structure built at the minimal required height for running the truck; the external wall and the inner separating wall is hollow ventilation wall, where the single-face hollow wall (1) of the external wall is made by the connection in parallel and overlaying of several ventilation units (16); double-face hollow wall (2) is made by the connection in parallel and overlaying of several ventilation units (17) in the inner separating wall, the multi-cell structure is formed by several units of double-face ventilation walls (2), each cell is a fermentation drying chamber (3) further comprising several ventilation horizontal pipes (4) and ventilation vertical pipes (5), the heat elimination, ventilation and air exhaustion passageway in the fermentation material (8) is formed by the connection of ventilation horizontal pipes (4), ventilation vertical pipes (5) and the hollow wall wind passageway (6), the chimney (7); ventilation horizontal pipes (4) and ventilation vertical pipes (5) are connected with the hollow wall wind passageway (6), reflux wind pipe (9), fan (10), reflux wind passageway (11) and horizontal ventilation passageway (12) to form heat wind reflux system; and the heat reflux system and temperature sensor (13), fan controller (14), air door of the chimney (15) form the reflux control system.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the Static aerobic fermentation drying tower.
