Abstract

An apparatus is equipped with first and second rotary shaft 3, 4 and a plurality of disks 40, 50 provided upright at equal intervals on the respective rotary shaft. The disks are heated or cooled from the inside, and a raw material is heated or cooled by bringing it into contact with the disk surfaces. Scraper members 45, 45′ and 55, 55′ that enter between the surfaces of the facing adjacent disks to scrape the raw material are fixed to each of the disks 40, 50. The first and second rotary shafts 3, 4 are rotated at unequal speeds such that the scraper members approach the facing disk surfaces with trajectories drawn thereon varying, so that the raw material that has adhered to the disk surfaces can be effectively scraped off.

Claims8

Dependent claims

An apparatus for heating or cooling a raw material in which a disk mounted on a rotary shaft is heated or cooled and the raw material is brought into contact with the disk surface, comprising:

first and second rotary shafts that are disposed in a facing manner;
a plurality of disks that are provided upright at intervals on the first rotary shaft;
a plurality of disks that are provided upright on the second rotary shaft so as to be shifted a predetermined distance from the disks of the first rotary shaft, respectively;
wherein a scraper member that enters between the surfaces of the facing adjacent disks to scrape the raw material is fixed to each disk of the first and second rotary shafts;
and
the first and second rotary shafts are rotated at unequal speeds such that the scraper member approaches the facing disk surface with a trajectory drawn thereon varying.
