ABSTRACT:
The material to be evaporated is continuously fed into a stationary vertical cylinder where it is heated to a boiling condition through the cylinder wall while scraping material from said wall and while rotating the material about a vertical axis to maintain an upwardly opening cavity therein. Vapors drawn from the cavity to concentrate the material are passed through a first path; and concentrated material is displaced through a second path along part of the cylindrical surface while in a cooled condition to arrest the boiling and while maintaining the two paths separated. The discharge pressure of the concentrated material is increased by imposing a substantial resistance to its rotation in the second path; and to permit control of the evaporation, a sensing device is inserted in the second path to indicate changes in the temperature of the discharging concentrated material, which is substantially free of vapor.
