Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for fractionating and crystallizing a paraffin from a crude paraffin based on a mineral oil and a synthetic crude paraffin. SOLUTION: A crude paraffin having a high oil content is crystallized in a crystallizer having a perforated metallic sheet extending in zigzags in each space between surfaces 39 of a heat exchanger, and a melt containing the paraffin is solidified to only an extent that a fraction and an oil to be discharged remain in a liquid form and the whole melt is discharged without solidification thereof. The perforated sheet is adapted so as to support layers of crystals and separate the paraffin as each belt piece 53 from the surfaces 39 of the heat exchanger during the sweating and mount the paraffin on the tilted perforated sheet. The paraffin belt piece 53 is kept in a contact state with the surfaces 39 of the heat exchanger while being guided and moved by the tilt of the perforated sheet and pushed toward the surfaces 39 of the heat exchanger along tilted surfaces 30 by its own weight.
