NOVELTY - An automatic treatment system comprises setting unit, controlling unit, driving unit, displaying unit, and alarming unit. A leftover treating device comprises housing, agitation tank, agitation shaft, and voltage supply unit. The body comprises a door for opening and closing an introduction opening into which leftover food is introduced. The introduction opening is engaged on the upper surface. The agitation tank is installed in the interior of the body and receives the leftover food. Microorganisms are introduced into the agitation tank.    USE - Automatic treatment system for leftover treating device (claimed).    ADVANTAGE - The system allows leftover food to be treated without bad smells by repeatedly and automatically performing heating and agitating the leftover food and decomposing the leftover food with microorganisms. The system eliminates generation of error when leftover food treating device is driven, and eliminates environmental contamination.    DETAILED DESCRIPTION - An automatic treatment system comprises setting unit, controlling unit, driving unit, displaying unit, and alarming unit. A leftover treating device comprises body (10), agitation tank (40), agitation shaft (50), and voltage supply unit. The body comprises a door (12) for opening and closing an introduction opening (11) into which leftover food is introduced. The introduction opening is engaged on the upper surface. The agitation tank is installed in the interior of the body and receives the leftover food. Microorganisms are introduced into the agitation tank. The agitation shaft is transversely engaged with a central portion of the agitation tank. The agitation shaft agitates the leftover food. The voltage supplying unit is in a control panel on one side of the body. The voltage supplying unit supplies voltages to driving sections. The setting unit receives an output voltage of the voltage supplying unit and sets control signals of the leftover food treating device. The controlling unit receives input data through the setting unit and controls the operational state of the leftover food treating device. The sensing unit is installed in the body and inputs measured data to the controlling unit. The driving unit receives the output signals of the controlling unit. The output signal is obtained by comparing and calculating the data input through the sensing unit and the data of the setting unit. The driving unit drives the leftover food treating device. The displaying unit displays the operational states of the setting unit, sensing unit, the driving unit, and controlling unit. The alarming unit displays an alarm setting value through the displaying unit and outputs a predetermined alarm sound, in the case of the alarm setting value of a program preset to the controlling unit. The setting unit comprises five switches, and test switch.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross sectional view of the leftover food treating device.
