  • METHOD FOR OBTAINING A VALUABLE PRODUCT, PARTICULARLY STARCH, FROM GRAIN FLOUR
    Publication number: 20100173358
    Abstract: A process for obtaining a starch and a protein or both from grain flour, the process steps comprising: providing grain flour; mixing the grain flour with processed or fresh water to form a slurry; separating the slurry into it at least two fractions, the at least two fractions including two or more of a heavy A-starch fraction, a protein and B-starch fraction, and a pentosan fraction; and generating a biogas from at least one of the fractions from the separating step, the biogas being used for generating energy.

  • Method for the fractionation of oil and polar lipid-containing native raw materials
    Patent number: 7550616
    Abstract: The present invention relates to a process for the production of polar lipid-rich materials and preferably phospholipids. Preferably the polar lipid-rich materials are separated and recovered from de-oiled native raw materials by extraction with water and alcohol and use of density separation to separate the resulting mixture. The invention also includes an improved process for de-oiling the native raw material before extraction and recovery of the polar lipids.

  • Process and apparatus for processing industrial waste water by electrolysis
    Patent number: 5549812
    Abstract: Electrolysis of water is effected while the water flow is pulsed utilizing pulse direct current in an electrolyzer having a medium flow between pairs of electrodes and a meandering flow from electrode pair to electrode pair, treating waste water and producing a flocculate which is removed in a stilling or settling tank cascade.
