Further, the space forming portion 31 has a recessed groove 312a formed by being embedded from the inner side.

The recessed groove 312a is formed in a shape corresponding to one end of the dividing portion 32 to provide a space into which one end of the dividing portion 32 is inserted so that the position of the dividing portion 32 in the inner space S2 .

The recessed groove 312a defines the fastening position of the space forming portion 31 of the partitioning portion 32 in the process of fastening the partitioning portion 32 and the space forming portion 31 to form the space forming portion 31 and the partition portion 32 in the assembling process.

One end of the partition 32 inserted in the recessed groove 312a is fixed to the space forming portion 31 by an additional operation by welding or the like.

The space forming part 31 includes a side part 311 connected to the curved part 11 and a placement part 312 spaced apart from the curved part 11 by a first length while being connected to the side part 311 .

Here, the first length is equal to the length of the width of the side portion 311, and the length of the partition 32 is also the first length.

The partition 32 is in contact with the curved portion 11 and the other end is brought into contact with the placement portion 312 so that the curved portion 11 and the placement portion 312 maintain a separation distance of the first length And prevents the arrangement part 312 from being detached from the curved part 11 through the curved part 11 and the arrangement part 312.

Specifically, the space forming part 31 is fixed to the screw cover part 10 by connecting the side part 311 and the curved part 11. At this time, the space forming part 31 is located in the inner space S2 of the space forming part 31 The partitioning portion 32 is simultaneously connected between the space forming portion 31 and the curved portion 11 so that the fixing force of the screw cover portion 10 of the space forming portion 31 can be improved.

If the space forming portion 31 is fixed to the screw cover portion 10 only by the connection of the side portion 311 and the curved portion 11, The connecting portion between the curved portion 11 and the space forming portion 31 may be broken or damaged. However, in order to solve such a problem, according to the present invention, the partitioning portion 32 disposed between the space forming portion 31 and the curved portion 11, Thereby reinforcing the rigidity.

The first partition 32a has the same structure as that of the partition 32 described with reference to Figs. 1 to 6 and the second partition 32b and the third partition 32c have the same structure as that of the first partition And 32a.

The first compartment 32a defines a first space V1 and the second compartment V2 and the second compartment 32b defines a second compartment V2 and a third compartment V3, The third partition 32c separates the third space V3 and the fourth space V4.

The first space V1 is a space adjacent to the vapor injection unit 33 and the fourth space V4 is a space farthest from the vapor injection unit 33. [

The steam introduced into the first space V1 has a high thermal energy due to the steam originally supplied by the steam injecting unit 33. However, the steam introduced into the second space V2, the third space V3, and the fourth space V4, The amount of heat energy is reduced, so that the temperature in the space gradually decreases from the first space V1 to the fourth space V4.

In one embodiment of the present invention, in order to lower the rate of temperature change from the first space V1 to the fourth space V4, that is, to efficiently move the vapor from the first space V1 to the fourth space V4 The size of the vapor transfer hole formed in the first compartment 32a may be larger than the size of the vapor transfer hole formed in the second compartment 32b and the size of the vapor transfer hole formed in the second compartment 32b may be larger than the size of the third compartment 32b, May be larger than the size of the vapor transfer hole formed in the portion 32c.

Specifically, the size of the passage of steam from the first space V1 to the second space V2 is made larger than the size of the passage of steam from the second space V2 to the third space V3 And the size of the passage of the steam from the second space V2 to the third space V3 is equal to the size of the steam from the third space V3 to the fourth space V4 So that the movement of the steam can be smoothly performed.

Thus, by minimizing the temperature difference in the space which is lowered from the first space V1 to the fourth space V4, it is possible to efficiently melt the frozen organic waste which is accommodated in the accommodation space S1.

In the description of the present invention, the number of the dividing sections is limited for the sake of understanding. However, as shown in the figure, the dividing sections may be formed in plural according to the installation position of the transfer apparatus and the working environment.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
