PURPOSE:To contrive to enhance the purity and recovery rate of a product, by forcibly refluxing a condensate by mounting reflux pipes to a large number of sections formed by dividing a condensing surface. CONSTITUTION:A raw liquid is supplied from a raw liquid feed pipe 19 to enter the liquid dispersing pipe 20 integrally rotated along with a rotary arm 17 and evaporated while scattered to an evaporation surface heated by a heating jacket 11. The generated steam is condensed in an uppermost stage recovery part S-1 and the condensate is collected by a receiver 21 to be taken out from a withdrawing pipe 23. The condensed liquids in the next recovery parts S-2, S-3 enter rotary receivers 26 from condensate receiving nozzles 25 and pass reflux pipes 27 by centrifugal force and refluxed to the liquid dispersing pipe 20 to be repeatedly subjected to evaporation. By this mechanism, the purity and recovery rate of a product are remarkably enhanced.
