Apparatus and process for cooling and de-steaming

The cooling of gypsum stucco has been of interest in the gypsum industry for many decades. Stucco is physically and thermodynamically unstable at high temperatures. In order to maintain its quality, the stucco should be quickly aerated and cooled below the temperature of calcination (250° F.). This is especially true when the calcined stucco is to be stored over time. Hot and
