1. A continuous hydrolyzation apparatus comprising:
a hydrolysis reaction container including a heating container including a feed portion for a hydrolytic resin composition and a feed portion for water;
a kneader configured to knead the hydrolytic resin composition with the water in the heating container;
a conveyor configured to convey the hydrolytic resin composition and the water to a downstream side in the heating container;
a pressure regulation valve provided on a downstream side of the hydrolysis reaction container and configured to have a hydrolytic resin composition product flow to the downstream side through the pressure regulation valve while setting a pressure in the hydrolysis reaction container to a prescribed pressure to promote a hydrolysis reaction; and
a seal formed at an upstream side of the feed portion for the water in a longitudinal direction of the heating container by using the hydrolytic resin composition melted under heat in the heating container, the seal being configured to seal a gap formed between the heating container and the conveyor.
