DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the invention, there is provided an underwater cut pellet transport method, in which pellets cut formed by an underwater cutting device are delivered to a cooling water dehydrating device and a drying device by means of the head pressure of a cooling water circulating pump and are dehydrated and dried there, the thus dried pellets are then delivered to a plurality of pellet silos by means of the head pressure of an air feed blower provided in a pneumatic feed facility, wherein the cooling water dehydrating device and drying device are respectively disposed above the pellet silos to thereby eliminate the need for provision of the pneumatic feed facility. Also, according to the present invention, the dry pellets from the drying device are supplied to the pellet silos in such a manner that they are allowed to fall down into said pellet silos naturally, that is, due to their own weights. Further, according to the present invention, the head pressure of the cooling water circulating pump is set in the range of 3-15 kg/cm. sup. 2. According to the invention, there is provided underwater cut pellet transport apparatus, in which pellets cut formed by an underwater cutting device are delivered to a cooling water dehydrating device and a drying device by means of the head pressure of a cooling water circulating pump and are dehydrated and dried there, the thus dried pellets are then delivered to a plurality of pellet silos by means of the head pressure of an air feed blower provided in a pneumatic feed facility, wherein the cooling water dehydrating device and drying device are respectively disposed above the pellet silos to thereby eliminate the need for provision of the pneumatic feed facility, and also in that the dry pellets from the drying device are supplied through a chute pipe to the pellet silos in such a manner that they are allowed to fall down into the pellet silos naturally, that is, due to their own weights. Embodiment Now, description will be given below of an embodiment of underwater cut pellet transport apparatus according to the invention with reference to the accompanying drawing
