Abstract

PURPOSE: To easily remove and separate a contamination of the surface of a synthetic resin pellet without washing with detergent or scraping the surface, by mixing a degreasing solid deterging agent to a circulating lift conveying path of the Pachinko balls and the synthetic resin pellet, for extracting and removing the fat and oil contamination attached to the surface of the synthetic resin pellet. CONSTITUTION: A small quantity of a degreasing solid deterging agent W is charged into as transverse pipe 3 from a supplying port 13 together with a synthetic resin pellet P. The synthetic resin pellet P and the degreasing solid deterging agent W are conveyed into a lift conveying pipe 2 together with the Pachinko balls B introduced into the transverse pipe 3 from a supplying port 12. The Pachinko balls B, the synthetic resin pellet P and the degreasing solid deterging agent W conveyed into the lift conveying pipe 2, are lifted toward and upper edge opening while being stirred and mixed by the rotation of a first spiral body 4. The contamination of the Pachinko balls B is attached to the surface of the synthetic resin pellet P, and the balls B are sufficiently polished, when the balls B, the synthetic resin pellet P and the degreasing solid deterging agent W are stirred and mixed by the first spiral body 4, and the contamination attached to the surfaced of the synthetic resin pellet P is removed by the degreasing solid deterging agent W.
