In addition, in this embodiment, the second dry air blowing device 180 is installed on the second guider G2, but is installed between the transfer device 120 and the transfer device 120 to blow dry air of high temperature and high pressure to the right. It can be, and its installation location can be variously modified.

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

In the present embodiment, the humidity sensor 190 is installed in the second crushing and stirring device 150, but if the humidity between the transfer device 120 and the transfer device 120 can be measured, the 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 the first and second dry air blowing devices 170 and 180 according to the humidity signal from the humidity sensor 190. It controls the air volume of hot air (dry air of 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 into the conveying device 120 at high pressure, as shown in FIG. 13 (refer to the arrow direction), the high-temperature and high-pressure dry air Is introduced into the transfer device 120, and then moves between the transfer device 120 and the transfer device 120 and the transfer device 120 to effectively discharge the humid air inside the drying chamber 110 (110) It improves the drying efficiency of organic waste by allowing the interior to be dried at high temperature.

In particular, in this embodiment, the first dry air blowing device 170 is provided, the upper transfer plate 124 positioned above the transfer device 120, and the lower transfer plate positioned under the transfer device 120 ( 124) a second dry air blower to allow the humid air stagnated between the air to move upward of the transfer device 120, and to transfer the moved humid air and the humid air located under another transfer device 120 By allowing 180 to move upward, as shown in FIG. 13, by forming an air discharge rod, drying of the organic waste can be made more quickly and effectively.

In this case, according to the present embodiment, the drying efficiency of organic waste may be further improved by adjusting the air volume of the first and second dry air blowing devices 170 and 180 according to a humidity signal from the humidity sensor 190.

For example, when the air humidity between the transfer device 120 and the transfer device 120 is low, the amount of hot air blown from the second dry air blowing device 180 is reduced, and the transfer device 120 and the transfer device 120 The efficiency of the entire drying process can be improved by allowing the air in between to sufficiently absorb moisture and then discharge it.

On the other hand, it is preferable that the first and second dry air blowing devices 170 and 180 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 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 and stirring devices 140 and 150 are installed, the organic waste can be finely crushed and stirred while drying. In this way, it is possible to achieve an efficient drying process by allowing more efficient heat supply to organic waste.

In addition, the present invention, as shown in Figure 9, by installing the first dry air blowing device 170 in the hopper (HP) of the second crushing and stirring device 150, the transfer plate ( When hot air is applied between the 124 and the transfer plate 124, the hot air moves between the inside of the transfer device 120 and between the transfer device 120 and the transfer device 120 to dry the inside of the drying chamber 110 at high temperature. Organic waste can further improve drying efficiency.

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

The present invention can improve energy efficiency and reduce the cost of drying operation, thereby creating a very high economic effect when used industrially.

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