    摘要: In case of thickening a feed resin without pre-drying, it is intended to enhance the thickening effect. In an apparatus for mixing a polyester resin continuously, comprising a chamber 4 having a material feed port 2 and a material discharge port 3, a mixing rotor inserted into the chamber 4 rotatably, vacuum pumps 8 and 9 for dehydrating the interior of the chamber 4 under reduced pressure, a material feed means 6 connected to the material feed port 3, and a chemical agent feed means 10 connected to the chamber 4 for adding into the chamber a chemical agent having a thickening function for the feed resin, a portion located upstream of the chemical agent feed means 10 in the chamber 4 is used as a drying section 14 in which the feed resin before the addition of the chemical agent thereto is subjected to mixing while being dehydrated under reduced pressure, and a portion located downstream of the chemical agent feed means 10 is used as a thickening section 15 in which the feed resin after the addition of the chemical agent thereto is subjected to mixing while being deaerated under reduced pressure.
