Calcined gypsum treatment device and calcined gypsum treatment method
[Problem] To prevent with certainty generation of condensation water in an area of contact between calcined gypsum and moisture and along a conveying path of reformed calcined gypsum, for example, in a process of reforming calcined gypsum in which calcined gypsum is reformed using a water adding treatment. [Solution] Provided is a calcined gypsum treatment device that includes: a stirring-type cooling device (1) which is provided with a cooling region (D) that cools calcined gypsum (G); and a water-adding device (20) that adds water to the calcined gypsum. The water-adding device includes a wet gas supplying port (22) through which a wet gas (S) containing moisture or water vapor is directly introduced into the cooling region. The calcined gypsum is reformed by being introduced into the cooling region from a calcined gypsum introducing port (16) of the cooling device and subjected to a water adding treatment in the cooling region. The wet gas supplying port is disposed close to the calcined gypsum introducing port, and a jet or discharge flow of the wet gas contacts the calcined gypsum immediately after the calcined gypsum has been introduced to the cooling region from the calcined gypsum introducing port.
