Abstract

The present invention relates to a pellet collecting apparatus. According to the present invention, even though a coolant passes through a dehydrator (30) to be dehydrated together with a cut pallet (P) from an extruder (B), moisture is still contained therein. Therefore, dry wind of a main blower (54a) is blown into a lower tunnel (52b) by passing through a wind inlet (50f) in a state of inputting the pallet (P) dehydrated in the dehydrator (30) into an upper tunnel (52a) of a collection box (52) through an upper inlet (50a), and is discharged to a wind outlet (50g) after passing through air holes (53a) and the upper tunnel (52a) as well as the lower tunnel (52b) so as to dry the moisture contained in the pellet (P) and to three-dimensionally dry even water drops falling from the pellet (P) through the dry wind passing through the lower tunnel (52b).
