CONSTITUTION: The automatic air supply and drainage system is disposed in a ventilation type compost fermenting device comprising a drainage path at the bottom of the fermenting chamber and having a blower, an air supplying duct and ventilating duct which are communicated one another. The system is characterized by comprising a fermenting chamber with a roof; a forced blower(10) for supplying air to the air supplying duct formed on the bottom of the fermenting chamber and an electronic valve(20) mounted at the end of the ventilating duct; and a central controller for opening and closing the ventilating duct before the operation of the blower(10) for supplying air to the air supplying duct or after a predetermined time. |
