The humidity sensor 190 is installed between the transfer device 120 and the transfer device 120 to measure humidity and output it to the controller 500.

In this embodiment, the humidity sensor 190 is installed in the second crushing stir device 150, but if the humidity between the transport device 120 and the transport device 120 can be measured, its installation position is variously modified. Can be.

The controller 500 controls the first and second dry air blowing devices 170 and 180 and the humidity sensor 190, and in accordance with the humidity signal from the humidity sensor 190, the first and second dry air blowing devices 170 and 180 It controls the air volume of the hot air (dry air at high temperature and high pressure) that is sent out.

In this embodiment, when the first dry air blowing device 170 blows high-temperature dry air at high pressure into the conveying device 120, as shown in FIG. 13 (refer to the arrow direction), high-temperature high-pressure dry air After being introduced into the transfer device 120, the transfer chamber 120, and moving between the transfer device 120 and the transfer device 120 while effectively discharging the humid air inside the drying chamber 110, the drying chamber (110) Since the inside can be dried at a high temperature to improve the drying efficiency of organic waste.

In particular, the present embodiment is provided with a first dry air blowing device 170 is provided with an upper transfer plate 124 located on the upper side of the transfer device 120, and a lower transfer plate located below the transfer device 120 ( 124) to allow the humid air stagnant between to move upwards of the transfer device 120, and move the humid air and the humid air located below another transfer device 120 to the second dry air blower By allowing the 180 to move upward, as shown in FIG. 13, an air discharge rod can be formed to more quickly and effectively dry the organic waste.

At this time, the present embodiment can further improve the drying efficiency of organic waste by adjusting the air volume of the first and second dry air blowing devices 170 and 180 according to the humidity signal from the humidity sensor 190.

For example, when the air humidity between the conveying device 120 and the conveying device 120 is low, the amount of hot air blown from the second dry air blowing device 180 is reduced, and the conveying device 120 and the conveying device 120 are used. It is possible to improve the efficiency of the entire drying process by allowing the air between them to absorb moisture sufficiently before being discharged.

Meanwhile, the first and second dry air blowing devices 170 and 180 preferably blow dry air (hot air) of high temperature and high pressure compressed by a compressor.

Here, the compressor receives high-temperature dry air from a supply line that supplies high-temperature dry air into the drying chamber 110, compresses it, and supplies it to the first and second dry air blowing devices 170 and 180, or separately. The high temperature dry air may be compressed and supplied to the first and second dry air blowing devices 170 and 180.

In the present invention, as shown in FIG. 4, when the transfer device 120 is arranged in multiple stages and the first and second crushing stirring devices 140 and 150 are installed, the organic waste can be finely crushed and stirred while drying. Thereby, it is possible to achieve an efficient drying process by making the heat supply to the organic waste more efficient.

In addition, according to the present invention, as shown in FIG. 9, the first drying air blowing device 170 is installed in the hopper HP of the second crushing stirring device 150 to transfer the plate of the conveying device 120 ( 124) and when the hot air is applied between the transfer plate 124, the hot air moves between the transfer device 120 and between the transfer device 120 and the transfer device 120 so that the drying chamber 110 is dried at a high temperature. Organic waste can further improve the drying efficiency.

In addition, according to the present invention, as shown in FIG. 11, the air in the drying chamber 110 is controlled through the control structures of the first and second dry air blowing devices 170 and 180 and the humidity sensor 190 and the controller 500. It can be used efficiently to improve the overall drying process efficiency.

As described above, the present invention can improve energy efficiency and reduce drying operation costs, and thus can create a very high economic effect when used industrially.

Although the present invention has been described in detail only with respect to the specific embodiments described, it is obvious to those skilled in the art that various modifications and modifications can be made within the technical scope of the present invention, and it is natural that such modifications and modifications belong to the appended claims.
