Sugar

Utilizing sugar containing crops.

Processing of sugar crops

Intermediate products or by-products of the sugar industry are an important source of raw material for the fermentation of bioproducts. (Vogelbusch proprietary processes in orange)

Treatment of sugar based feedstocks

Clean molasses and sugar syrups can be fed straight to the fermentation unit. Treatment is required only for raw molasses containing sludge or certain quantities of inhibiting substances which would affect the fermentation.

  • Molasses preparation

    Clarifying and contamination control.

    Concepts

    Raw molasses is a by-product of refining sugarcane or sugar beets. It contains a portion of sugar that could not be crystallized into white or raw sugar as well as water, ashes and other organic compounds. For optimum yields in the fermentation process, microbial contamination and inhibiting substances contained in raw molasses have to be detected and removed.

    Applications

    Raw molasses is mixed with water and sulphuric acid and clarified by sedimentation or by separators. If pasteurization is required, the clarified molasses can be fed to a sterilisation coil where it is heated with live steam at a specific temperature and afterwards cooled down.

    RAZI YEAST & ALCOHOL Co. - Ahwaz, Iran

    The plant now operated by Razi (formerly Sugar Cane By-Products Corporation) was designed for a daily capacity of 110,000 litres of high quality pharmaceutical alcohol from cane molasses complying with EU standards. A special challenge was designing the plant for the extreme climatic conditions (0°C to 50°C) and the highest...

  • Precipitation

    Sedimenting insoluble solids from liquids.

    Concepts

    Precipitate reactions occur when different ions in aqueous solution combine to form an insoluble solid. This process can be induced by application of reagents that precipitate specific ions or by neutralizing target components. The precipitate drops to the bottom of the liquid for easy removal or is separated from the liquid by additional equipment like filters or centrifuges.

    Applications

    Vogelbusch has comprehensive experience in designing precipitation units. It is used to clarify liquids from undesired substances as well as for product isolation. Applications include raw material preparation for fermentation by removing inhibitors, the fining of raw vinegar to bind and remove dissolved substances and the isolation of citric acid from the fermented mash.
