Abstract
The present invention relates to an improved method of drying the extracted beet chips and means and equipment for carrying out the method, with emphasis especially on the reduction of the emission of organic carbon compounds during the chip drying stage and on the reduction of the primary energy consumption.
Claims16
A method of drying extracted beet chips, comprising the steps:
- combining an alkaline colloid fraction which is a non-sucrose concentrate comprising starch colloids, cellulose colloids, pectin colloids, hemicellulose colloids, lignin colloids, protein colloids and mixtures thereof, with sugar extracted beet chips, wherein the quantity of alkaline colloid fraction is 0.1 to 0.8 kg dry matter per 100 kg of the sugar extracted beet chips;
- and
- immediately drying the sugar extracted beet chips by thermal removal of residual water, wherein the energy consumption for drying of the sugar extracted beet chips is reduced relative to the energy consumption when drying the sugar extracted beet chips without employing the alkaline colloid fraction.
