Title: Improvements in methods of and means for refining sugar and the like
IPC: C13B30/12
Filed: 1930-10-31
Abstract: Sugar is obtained by extracting a solution of sucrose from a sugar-bearing plant, treating said solution of sucrose to obtain raw sugar therefrom, treating said raw sugar to obtain refined sugar and syrup therefrom, and returning said syrup to the process for admixture with the sucrose solution for the separation of additional raw sugar.  The process is made continuous.  The sugar cane or other sugar-bearing plant is crushed and macerated and the juices are limed, heated and separated from the scums and mud which are further treated to separate entrained juices.  The juices are then evaporated to a syrup of suitable density to form "meladura" which passes to crystallizers.  The mother liquor is passed to a centrifugal for separating raw sugar and the liquor is sent to a second and third crystallizer for the separation of more raw sugar.  The raw sugar from the third crystallizer is used for seeding purposes, while that from the first two is treated with decolourizing carbon and filtered to obtain white sugar.  The residual run-offs are returned to the first raw sugar crystallizer or to the first evaporators.  Details of crushing, liming, defecting, settling, evaporating and filtering are described.
