The typical scheme of sugar beet processing, used at
most sugar beet factories in Russia has not been
fundamentally changed for several dozens of years. As
a result, the performance indicators of domestic beetprocessing
enterprises are below the world average.
The article considers the technology of two-stage
extraction and subsequent lime-carbon dioxide raw
juice purification with the separation of the preliming
sludge and carrying out the carbonation treatment in
one step. The theoretical foundations of a two-stage
extraction of sucrose from sugar beet cossettes are
described and the main criteria for its implementation
are given. The chemistry of calcium compounds upon
activation of a suspension of saturation precipitation,
returned to a progressive preliminary defecation, is
shown. On that the increasing of sedimentationfiltration
properties of the preliming sludge is based
that allows its separation on the existing equipment in
based. The theoretical premises for carrying out
saturation in a homogeneous liquid-liquid environment
are given and practical principles for their realization
are described. The comparative evaluation of existing
and improved sugar beet processing technologies is
carried out. The improved technology makes it
possible to reduce the amount of raw juice while improving its purity, thereby reducing the
consumption of auxiliary materials, fuel and energy
resources, simplifying the technological scheme while
improving the quality of the purified juice, namely, its
higher purity, achieved by reducing the degree of
transition of high-molecular compounds in it and
increasing the effect of destruction of reducing
substances
Sulphitation of semiproducts of sugar production has a
significant influence on the course of processes in the
refining of both sugar beet and cane sugar. The
insufficient degree of adsorption of sulfurous
anhydride has a negative impact on the environment as
well as on the technical staff, if it gets into production
premises, caused not so much by contingencies, but by
shortcomings in the equipment used. In the article, we
describe the main types of constructions of sulphitation
devices used in the sugar industry, their drafts are
shown, their advantages and disadvantages are
considered
