Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for the continuous granulation of bisphenol F dispensing with a maintenance work over a long period and provide a granulating machine therefor. SOLUTION: Molten bisphenol F is cooled to obtain a semi-solid having a solidification degree of 60-98% and the semi-solid is supplied to a granulating machine and granulated in a state maintained at 50-100 deg.C. The granulating machine is provided with screws 4A, 4B each having a hollow part 41 along the central axis and insertion pipes 5A, 5B for passing heating fluid. Each of the insertion pipes has an opening 52 at the tip end and is inserted into and fixed to the hollow part interposing a definite gap 43 between the outer circumference of the pipe and the inner circumference of the hollow part. A heating fluid is passed through the hollow part 41 of the screw via the insertion pipe and the gap 43.
