りしてスケーリング等の原因となる。In general, in continuous processing such as crosstalk single reaction of highly viscous substances, the dead space in the equipment should be kept as small as possible.
Moreover, an operation similar to that of an extrusion flow is required. For this purpose, various designs have been devised in which a horizontally long cylindrical container is used and two stirring blades are installed in the longitudinal direction. For example,
As shown in No. 2-29019, there is a structure in which paddle blades are arranged in multiple stages to scrape the entire inner surface of the container to reduce the dead space, but if the liquid to be treated has a high temperature of several thousand poise or more, If the liquid becomes viscous, the liquid adhering to the surface of the rotating shaft may rotate together, causing problems such as scaling. Therefore, an attempt was made to eliminate this rotation axis and reduce the rotation, and
As proposed in the above issue, there is a system in which the outer periphery of a partially hollowed out disk is connected and the rotating shaft is removed. The wilt-causing liquid adhering to the surface of the disc-shaped stirring blade flows and circulates around the blade, causing scaling.

内側で液を持ち上げる方向に撹拌”J45a。When performing condensation polymerization of polyethylene terephthalate, polycarbonate, etc., the viscosity of the liquid to be treated increases from several thousand voids to tens of thousands of voids due to the polymerization reaction. Due to the stirring action, dead spaces can be almost completely eliminated, and furthermore, a good surface renewal action can be obtained, and a high-quality polymer can be obtained. Volatile matter such as ethylene glycol that is produced as a by-product at this time is discharged from the volatile matter outlet nozzle 9 via a vacuum device (not shown). In such a direct operation for removing volatile matter from a liquid, the ice bag is stirred in the direction of lifting the liquid inside the container body 1.
