PROBLEM TO BE SOLVED: To provide a centrifugal filtration apparatus in which the recovery rate of crystals in a basket can be increased without making a centrifugal filtration apparatus have a complicated structure. SOLUTION: The basket 10 is supported in a casing 7 with the center axial line of the basket 10 kept in the horizontal direction. The apparatus is provided with a crystal sucking pipe 21 having a rotary part 21b rotating in the basket, and a plurality of scraping blades 22A, 22B and 23 are attached to the crystal sucking pipe. While the rotary part 21b of the sucking pipe 21 is rotated to displace its top end to the crystal side on the inner wall of the basket 10, the scraping blades 22A, 22B and 23 are made to intrude into the crystal to scrape the crystal. The direction of the blade face of each scraping blade is determined in such a manner that the scraped crystal is guided along the blade face of each blade to the final sucking position as the final reach point of the top end of the sucking pipe 21.
