  • Vacuum filtration process
    Patent number: 3969247
    Abstract: An improved process for dewatering sodium bicarbonate solids and similar substances formed as a cake on a rotary drum vacuum filter that is disposed for rotation in partial submergence in a slurry containing the suspended solids. The process includes the steps of pressing the filter cake against the surface of the filter drum by means of a pressure-applying roll which is driven to rotate so that its surface velocity exceeds the velocity of the drum surface by 25 to 75% and, thereafter, drawing steam through the filter cake while it is still on the surface of the filter drum.
