ABSTRACT:
The present invention is directed to a whirlpool type high speed cooler comprising a cooling cylinder having a bottom drain hole. An upper chamber, a circular channel and a cooling chamber are provided within the cooling cylinder by plurality of plates. The circular channel is capable of forming a column of cooling water about the inner walls of the cooling chamber and has holes and guide plates adjacent to the inner wall cooling cylinder for this purpose. A convex head drum extending laterally at upper portion of the cooling chamber is provided for guiding water into the circular channel through the holes and against the guides in the circular channel thereby creating a whirlpooling column of cooling water about the inner wall of the cooling chamber. A revolving plate located in the cooling cylinder has a plurality of inclined cutter blades at its circumference. A mold is arranged in the upper chamber of the cooling chamber and abuts the revolving plate. The whirlpool high speed cooler is arranged so that plastic is fed into the mold and is cut into grains, and the grains are forced towards and mixed with the whirlpooling of columnar cooling water about the inner wall of the cooling cylinder and then washed out of the cooling cylinder through the drain hole.
