Sugar processing

Sugar processing

During the sugar production process, impurities coming from the soil and the beet can contribute to increased foaming.

Foaming issues during sugar processing

The foaming causes well-known undesired bottlenecks in production as:

  • higher energy costs
  • limited transportation of the sugar juice
  • decreased tank capacity
  • material loss
  • inefficient settling
  • slower evaporation and crystallization process resulting in higher energy consumption
  • extra downtime due to cleaning of equipment

Antifoaming agents and processing aids

Foaming issues limit the capacity and cause extra work for factory personal, decreasing profitability. To prevent these negative effects, LEVACO developed the following antifoaming agents and processing aids for the food industry:

Processing of sugar beets
DEFOSPUM® BIO for organic production

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.

DEFOSPUM® antifoaming agents for beet washing

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.

DEFOSPUM® antifoaming agents for higher process temperatures

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.

DEFOSPUM® pan aids for crystallization

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.

DEFOSTAB® 220 natural biostabilizer to substitute formaldehyde

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.

DEFOFLOC® for more efficient settling

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.

DEFOSCALE® against scaling

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.

Our products are approved as auxiliaries for the food industry, in line with the appropriate EU, EC, BfR and FDA regulations and are Kosher and Halal certified.
