On the screen of the display means 10, for example, as shown in FIG. 4, an input mode for inputting control parameters for controlling the processing device 1 and a current information display mode for displaying the state of the current contents in real time. Three selectable selection items 41, 42, and 43 are displayed: a history information display mode for displaying the state of the contents from the start of the content disassembly process to the present. However, it may be a display mode changeover switch.

  When the control parameter input mode is selected on the screen, various parameter setting items 44, 45, 46 and 47 are displayed as shown in FIG. In this case, by selecting and executing any one of the setting items 44, 45, 46, and 47, the screen shifts to the parameter input screen, and the control parameter can be input.

  When the display mode for displaying the current information of the content on the screen is selected, the current state of the content, that is, the weight, moisture content, temperature, pH, content of the content stored in the data memory 33, the processing tank 3 The carbon dioxide concentration, oxygen concentration, ammonia concentration, accumulated carbon dioxide generation amount, and decomposition amount of contents are displayed in real time. For example, as shown in FIG. 6, the content information is displayed in a plurality of display items 51, 52, 53, 54, 55, and 56.

  When a display mode for displaying history information of contents is selected on the screen, the screen shifts to a history information selection screen as shown in FIG. In this screen, information indicating the state of the contents from the start of the decomposition process, that is, moisture content transition, weight transition, temperature transition, pH transition, carbon dioxide concentration transition, oxygen concentration transition A plurality of selection items 61, 62, 63, 64, and 65 for selecting history information of transition of ammonia concentration, transition of accumulated carbon dioxide generation amount, and transition of decomposition amount are displayed, and one of the selection items is selected. By doing so, the screen display is switched and the history information is displayed.

  The history information displayed on the screen is represented by a graph. For example, when temperature history information is selected on the selection screen of FIG. 6, as shown in FIG. 8, the temperature transition history information stored in the data memory 33 is a graph 66a with the vertical axis representing temperature and the horizontal axis representing time. Is displayed.

FIG. 8 shows the history information of the temperature when temperature sensors are arranged at different points of the processing apparatus 1, and graphs 66b and 66c are simultaneously displayed in addition to the graph 66a. In this way, it is easy to visually grasp the same type of history information.

  When the history information on the accumulated carbon dioxide generation amount is selected on the selection screen, as shown in FIG. 9, the history information on the transition of the cumulative carbon dioxide generation amount stored in the data memory 33 has a vertical axis indicating carbon dioxide. The accumulated generation amount is displayed in a graph 67 with the horizontal axis as time. In this case, the items 68 and 69 for switching and displaying the accumulated carbon dioxide generation amount and the history information of the carbon dioxide concentration related to the cumulative carbon dioxide generation amount are displayed on the screen. By executing it, you can quickly switch screens and check other history information. That is, another history information can be displayed by quickly switching the screen.

  Note that the display form of the history information is not limited to a graph, and may be displayed with numbers or the like. Moreover, although the display means 10 is configured as a touch panel type, an operation means may be separately provided and configured from a liquid crystal panel, a CRT display, an EL display, or the like.

  Therefore, the history information of the contents from the start of the decomposition process of the organic waste in the processing apparatus 1 to the present can be easily visually confirmed by the display means. Therefore, the history information of the contents displayed on the display means 10, for example, the temperature of the contents that can be confirmed in FIG. 8, rises as the decomposition process proceeds, falls after reaching a peak, and maintains a substantially constant temperature. Since it is possible to easily confirm the temporal change of contents from simple information, it is possible to easily grasp the progress of the decomposition process.

  Furthermore, in the decomposition process, it is possible to display the estimated time of completion of the process, and it is possible to estimate the cause of the stagnation of the decomposition process, so that fermentation failure can be improved during the decomposition process. In addition, when the manufactured compost is used as a product, it is possible to display the history information until composting in addition to the general fertilizer components, etc., in the container filled with compost, which clearly shows the traceability of the product. Can increase the reliability of compost quality.

  In addition, the history information display form includes each element (water content transition, weight transition, temperature transition, pH transition, carbon dioxide concentration transition, oxygen concentration transition, ammonia concentration transition, carbon dioxide cumulative generation amount By displaying the upper and lower limits and displaying the appropriate area so that the appropriate range according to the type of compost can be seen, It is possible to easily estimate the fact that it is becoming abnormal, the occurrence of an abnormality, the missing element, and the like.
