Document Type and Number:

Japanese Patent JP4206837

Kind Code:

B2

Abstract:

The present invention provides an apparatus for the purpose of drying or solid phase polymerization of Polymer particles by batchwise heating the same in an atmosphere of inert gas or under reduced pressure. More particularly, it pertains to batchwise heating apparatus which is capable of efficient production by preventing an objective product from being contaminated with foreign matters accompanying wear of a sealing packing. It relates to a batchwise heating apparatus which heats Polymer particles in a rotating hermetically sealed vessel in an atmosphere of inert gas or under reduced pressure, and which comprises a vessel equipped with a temperature detection portion capable of measuring temperature even during rotating and a suction/exhaust port inside vessel capable of reducing pressure and/or replacing with inert gas even during rotating; and a suction/exhaust pipe that is inserted into vessel so as to communicate with the suction/exhaust port, wherein the rotational sealing portion of the suction/exhaust pipe is installed on the outside of the vessel.
