摘要：
The invention relates to a method and a device for increasing the intrinsic viscosity of polyester material by means of solid phase polymerisation. According to said method, the polyester material is thermally treated in a thermal treatment tank (6), after having being introduced into a pre-heating tank (2) prior to being fed to the thermal treatment tank (6). In the pre-heating tank, the material is heated to a thermal treatment temperature that equals or exceeds that of the thermal treatment tank (6) and once at this temperature is delivered to the thermal treatment tank (6). The pre-heating tank (2) is small compared to the thermal treatment tank (6), so that the relatively small quantity of polyester material contained in the pre-heating tank can be rapidly heated to the designated temperature and only resides in the pre-heating tank for a short time. Once the designated temperature has been reached, the entire contents of the pre-heating tank can be delivered in one step to the thermal treatment tank and the pre-heating tank can be subsequently recharged with polyester material. As a result of the short residence time, the pre-heating tank is suitable for operation in discontinuous mode.
