Sugar processing

Customers are looking for bio and organic products, and sugar factories are trying to keep up with the demand by increasing organic sugar production. To support them, LEVACO developed antifoaming agents suitable for the strict requirements of organic production process.

At the beet washing, surface-active substances like saponins, sugar and degradation products are dissolved in the transport water, generating undesired foam. A so-called outside antifoaming agent is used to handle foaming in this cold process.

At the diffusion, extraction, carbonation and evaporation processes the process temperatures are much higher than during the beet washing process. Therefore, this process requires a different antifoaming agent: inside defoamers used here should have low surface tension, good dispersion character and fast foam breaking effects.

At the crystallization centrifuges, a special antifoaming agent called pan aid is used to reduce the viscosity of the syrup, improving the rate of crystallization, thus decreasing energy consumption and increasing productivity.

To fight bacteria and control lactic acid development, sugar factories used formaldehyde in the past, which is a hazardous chemical causing occupational health and handling issues. To offer a safe alternative to formaldehyde, LEVACO supplies a unique and sustainable natural biostabilizer produced from raw materials of native origin, listed as a processing auxiliary for conventional and organic sugar production. The DEFOSTAB^® 220 biostabilizer can aid or replace formaldehyde to control lactic acid levels in various stages of sugar production, subsequently reducing sugar losses, enhancing occupational safety and easier handling, not being a hazardous chemical.

To enhance the performance of settling tanks in carbonation, water treatment and other processes, flocculating agents are used. We offer a wide range of anionic and cationic flocculants of different molecular weights.

Scale prevents effective heat transfer in the evaporator stages, leading to increased energy costs and production losses. DEFOSCALE^® VZK scaling inhibitor prevents the scale formation in evaporators caused by the presence of hardness components in the sugar juice.
