The closure plates 25 are fixed to the openings at both ends and the inside of the cylindrical rotating body 24 forming the casing 3.
Air intake ports 25 open to each closing plate 25 except for
Outside air is naturally drawn into the interior of the cylindrical rotor 24 from below through the air outlets 24a... which open onto the outer surface of the cylindrical rotor 24, and air is discharged radially (in the direction of the arrows). This air actively transports the resin pellets to the inner surface of the cylindrical filter 12, providing sufficient centrifugal force for dehydration.

脂ペレツトより水分や塵埃等を分離する。 Next, the resin pellets are supplied into the casing 11 through the supply port 14, and then the impeller 1 rotates.
It is wound up by each impeller 26 of 3, and each impeller 2
The resin pellets are flicked upward and outward by the inclined upper surfaces of the cylinders 6 and 6, flying around inside the cylindrical filter 12 at high speed, spiraling upwards, and reaching the inner circumferential surface of the cylindrical filter 12. The resin pellets are forcibly transferred to provide sufficient centrifugal force for dehydration.
Moreover, the resin pellets are violently collided with the circumferential surface of the cylindrical rotating body 24, each blade 26, and the inner circumferential surface of the cylindrical filter 12 to separate moisture, dust, etc. from the resin pellets.

Air is exhausted to the outside of the machine from the cylindrical portion 41, and the resin pellets are discharged from the opening 39a at the lower end of the outer cylindrical portion 39 to obtain dehydrated resin pellets.

る。 Since the cylindrical rotating body 24 is sealed off from the outside in this way, it is possible to reliably prevent resin pellets from remaining inside or on the outer circumferential surface of the cylindrical rotating body 24 during the dehydration process or at rest. Moreover, since the dehydrated resin pellets are reliably discharged from the discharge port 15 at the top of the casing 11, residual resin pellets are not mixed into new resin pellets when changing the color of the resin pellets or changing raw materials. There is no problem at all, and the raw material can be reliably replaced with the specified resin pellets, and the dehydration process can be performed efficiently.

When the lid 17, the support shaft 28, and the cylindrical rotating body 24 are lowered together, the lid 17 can close the upper end opening of the casing 11, and the support shaft 2
By fitting the spline portion 28a at the lower end of the support shaft 28 into the spline hole 30a on the bearing 30 side, the support shaft 28 can be supported on both sides. lid body 17,
By raising the support shaft 28 and the cylindrical rotating body 24 integrally, the cylindrical rotating body 24 can be easily taken out from inside the casing 11, which greatly reduces maintenance when changing raw materials and during periodic inspections. This has the effect of making it possible to improve the situation.
