Figure 3 is a perspective view of the main cutaway showing the collector 50 applied to the pellet collection device according to the present invention.

The collector 50 applied to the pellet collecting device according to the present invention is bounded by a horizontal frame 53 having a base frame 51 supported on the ground and air holes 53a as shown in FIGS. 2A to 3. Pellets passing through the upper inlet (50a) and the upper channel (52a) to guide the pellet (P) dehydrated in the dehydrator 30 to the upper channel (52a) having a furnace top (52a) and the lower channel (52b). Each of the other outlets 50b for discharging (P) is provided to communicate with the collection box 52 mounted on the base frame 51 and the air inlet 50f provided on one side of the collection box 52, and the upper inlet ( While drying the pellets (P) guided to 50a) to the other side outlet (50b) and blows dry air toward the air holes (53a) and the upper channel (52a) via the lower channel (52b) to collect at the same time It includes a main blower (54a) to let dry air escape to the outlet 50g provided on the other side of the box 52.

In addition to the pellet (P) cut from the extruder (B), although the cooling water is dehydrated while passing through the dehydrator (30), it still contains water, so that the pellet (P) dehydrated in the dehydrator (30) has an upper inlet (50a). Blowing dry air of the main blower 54a through the blower port 50f into the channel 52b through the inlet 50f in a state where it is introduced into the channel 52a from the top of the collection box 52 through air together with the channel 52b.
