  The internal cleaning button 10e is an operation button for instructing the internal cleaning of the processing container 1 as one of the processing condition information, and includes a normal cleaning button 10e1 and a careful cleaning button 10e2 as illustrated. The normal cleaning button 10e1 is an operation button for instructing normal internal cleaning by causing the processing container 1 to run idle under a processing condition of relatively low pressure (for example, 1 atm). The careful cleaning button 10e2 is an operation button for instructing a relatively careful internal cleaning by causing the processing container 1 to run idle under a processing condition of a relatively high pressure (for example, several atmospheres).

  The control panel 11 sets processing conditions based on the processing condition information and operates the processing container 1 and includes a microcomputer 11a, a processing condition setting table 11b, drive circuits 11c to 11e, and the like. The microcomputer 11a will be described in detail later, but the microcomputer 11a has various processing condition information input from various operation buttons of the operation panel 10, the internal temperature of the processing container 1 input from the pressure gauge 5, and the thermometer 6. The drive circuits 11c to 11e are driven based on the input internal pressure of the processing container 1 and the open / close state of the open / close door input from the lock pin 2, respectively. Further, the microcomputer 11a sets a specific processing condition in the processing container 1 by searching the processing condition setting table 11b based on the various processing condition information.

  The processing condition setting table 11b is a table in which processing conditions corresponding to the various processing condition information (search conditions) are registered in a table format. FIG. 3 is an explanatory diagram showing the processing conditions registered in the processing condition setting table 11b. The processing conditions registered in the processing condition setting table 11b are data defining the time change of the internal temperature of the processing container 1 or the internal pressure of the processing container 1 as shown in FIG.

The drive circuit 11e drives the drain discharge valve 7 under the control of the microcomputer 11a.

Next, operation | movement of this organic waste processing apparatus which has such a structure is demonstrated.
First, when the operator opens the opening / closing door to store the organic waste X in the processing container 1 and further closes the opening / closing door, the lock pin 2 is activated and the processing container 1 is closed. When the microcomputer 11a detects that the processing container 1 is closed by detecting the operation of the lock pin 2, the microcomputer 11a controls the driving devices 11c and 11e to close the exhaust valve 3 and the drain discharge valve 7. To do. In this state, the processing container 1 is in a sealed state.

  Further, the operator operates the type selection button 10a, the shape selection button 10b, the processing amount selection button 10c, and the processing object use selection button 10d on the operation panel 10, respectively, so that the organic waste X stored in the processing container 1 is obtained. When the processing condition information including the type, shape, processing amount, and use and purpose of the processed material is input, the microcomputer 11a searches the processing condition setting table 11b based on the processing condition information, thereby obtaining the processing condition information. The corresponding specific processing condition is read from the processing condition setting table 11b, and the vapor decomposition process of the organic waste X according to the specific processing condition is started.

  That is, the microcomputer 11a satisfies the processing conditions shown in FIG. 3, that is, the change in the internal temperature, that is, the internal pressure (saturated water vapor pressure) of the processing container 1 from the start of the processing to the end of the processing matches the specific processing conditions. Thus, the opening of the air supply valve 8, that is, the supply of water vapor to the processing container 1 is adjusted via the drive circuit 11 d.

  Then, when the vapor decomposition of the organic waste X according to such specific processing conditions is completed, that is, the processing time defined by the specific processing conditions has elapsed from the start of the processing, and further, the processing panel 10 When the discharge instruction is input, the microcomputer 11a controls the driving devices 11c and 11e to open the exhaust valve 3 and the drain discharge valve 7.

  As a result, the liquid component generated by the vapor decomposition, that is, the extract extracted from the organic waste X is discharged to the outside through the drain discharge valve 7, while the liquid component generated by the vapor decomposition is discharged from the exhaust valve. 3 is discharged to the outside as exhaust gas. And the solid component produced | generated by steam decomposition is taken outside by opening an opening-and-closing door.

  On the other hand, when the processing container 1 is operated without containing the organic waste X in the processing container 1, the inside of the processing container 1 and the inside of the piping communicating with the processing container 1 are washed with water vapor. That is, when the operator closes the open / close door without accommodating the organic waste X in the processing container 1 and further operates the normal cleaning button 10e1 or the careful cleaning button 10e2 among the internal cleaning buttons 10e, the microcomputer 11a A specific processing condition corresponding to the internal cleaning button 10e operated by the operator is acquired from the processing condition setting table 11b, and the processing container 1 is operated (empty operation) so as to follow the specific processing condition. As a result, the inside of the processing container 1 and the piping communicating with the processing container 1 are cleaned according to the specific processing conditions.

  As described above, in this organic waste treatment apparatus, when the operator inputs the processing condition information from the operation panel 10, the microcomputer 11a searches the processing condition setting table 11b to perform a specific process corresponding to the processing condition information. Conditions are automatically set and the organic waste X is vapor-decomposed. That is, in the present organic waste treatment apparatus, it is extremely easy to set treatment conditions for various organic waste X, and even an operator with little specialized knowledge about the treatment conditions can use various organic wastes. The product X can be easily subjected to steam decomposition, and is extremely convenient. In addition, since the inside of the processing container 1 and the inside of the pipe communicating with the processing container 1 can be easily cleaned by operating the internal cleaning button 10e, the maintainability is also high.
