The raw material 10 accommodated therein through the first inlet 110 undergoes two melting steps. More specifically, the raw material 10 received through the first inlet 110 formed on the upper side of the first melting part 100 is the raw material 10 through the impurity removing part 170 in the first melting step. ) after removing the impurities 30 contained in the inside, it undergoes a process of melting and extruding by the high heat applied to the inside of the first melting part 100 . Here, the impurity removal unit 170 may include a filter, a removal plate, a collection unit, a sieving unit, and a sieve.

The raw material 10 is discharged as the first melt 20 through the first melt portion 100 . The impurities 30 that may be included in the raw material 10 are removed, and the melted and extruded primary melt 20 is discharged through the primary outlet 150 .

A cooling tank allowing a certain volume therein to cool the secondary melt,
Cooling water maintaining a certain level of height in the cooling tank;
Containing a cooling unit conveying means for cooling the secondary melt accommodated therein and at the same time conveying to the receiving unit,
The cooling tank is
Including water cutting for processing the secondary melt into processed pellets having a certain size and shape,
The secondary melt is placed in the cooling water to have the shape of a processed pellet having a certain size and shape through the water cutting before being cooled, so that cooling and processing can be made easier, thereby improving the commercial properties of the processed pellet,
The cooling tank is
and a cooling unit inlet in which the water cutting is disposed in order to inject the secondary melt therein;
Further comprising a cooling unit outlet for being transferred through the cooling unit conveying means and delivered to the conveying unit at the same time as cooling,
so that the secondary melt processed into the processed pellets can be cooled inside the cooling tank without being affected by the external environment,
The transfer unit,
A conveying roller for conveying the secondary melt discharged through the cooling unit outlet to the receiving unit, and the secondary melt that is provided at the lower end of the conveying roller and can be removed in the process of conveying through the conveying roller Includes a pedestal to contain coolant,
The conveying roller,
One side is formed at the end of the cooling tank, and the other side is formed at the entrance of the receiving unit, and set to have a certain angle so as to be inclined upward from the cooling tank to the receiving unit,
When the secondary melt processed into the processing pellets is transported on an obliquely inclined surface when transported through the transport roller, the cooling water falling off the surface of the secondary melt is contained in the pedestal, while the secondary melt Pellet manufacturing apparatus, characterized in that the surface water can be removed naturally during the transfer process.
