1. multiaxis spiral machine that is used for the polymer melt devolatilization comprises:

  • -housing (2;

    2a;

    2b), described housing has a plurality of housing section (3~

    9;

    3~

    5,6a, 7,8a,

         9) and in described housing, form at least two housing bores (12,13), described at least two housing bores are parallel to each other and penetrate each other;

    -at least two axles (16,17), described at least two axles are arranged in the described housing bore (12,13) with one heart and can be driven with rotary way around relevant pivot center (19,20);

    -be used to handle a plurality of treatment elements (33~

    37) of polymer melt, described a plurality of treatment elements along the direction of corresponding pivot center (19,20) to be arranged in described at least two axles (16,17) before and after the nonrotational mode and to go up and tight engagement each other;

    And-at least one is used for removing the devolatilizer (38,39 of the contained volatile component of polymer melt;

    38a, 39a, 38b, 39b),It is characterized in that-described at least one devolatilizer (38,39;

    38a, 39a, 38b 39b) has devolatilization unit (40,41;

    40a, 41a;

    40b, 41b),--described devolatilization unit is from described housing (2;

    2a;

    2b) in described housing bore (12,13), extend to described axle (16,17),--described devolatilization unit is designed to, and makes the surface area of polymer melt in described devolatilization unit (40,41;

    40a, 41a;

    40b 41b) goes up increase.
