  • Method for continuous drying of a material and an assembly for carrying out said method
    Patent number: 5172487
    Abstract: A method for the continuous drying of a material. The temperature of the material is adjusted to below the boiling point of the material at atmospheric pressure. The material is fed into a vacuum chamber and led through the vacuum chamber without a heat supply. Then the dried material is removed through an air lock. The method can be carried out by an assembly including a mechanism for adjusting the temperature of the material, a feeding mechanism for feeding the material into a vacuum chamber, a vacuum chamber, a mechanism for transporting the material through the vacuum chamber and an air lock. The method and assembly are useful for drying materials which are sensitive and/or difficult to solidify.
