Abstract:
A starch wet milling process, in which a series of independent classifications and separations is carried out in the production of starch, employs a Starch Gluten Separation Station having a three-stage centrifugation treatment including passing the entire mill stream through a mill stream centrifuge thickener, followed by primary starch centrifuge separation and gluten centrifuge thickening.
Abstract:
Apparatus and method for producing gluten and starch from a dispersion of wheat, barley or rye endosperm fractions in water. The raw grain is initially milled to produce endosperm fractions suitable for carrying out the subsequent steps of the process. The steps taken in the milling process include breaking the raw grain between a series of fluted rollers, sorting the bran from various grades of semolinas, sizing coarse semolinas by the cutting action of fluted, opposed rollers, pressing and impacting coarse and fine semolinas by a series of smooth, opposed rollers and dissipaters, and finally reducing the tailing from the pressing and impacting steps in a series of smooth or fluted rollers, and dissipaters.
Abstract:
A process for recovering starch and corn oil from corn kernels. The corn kernels are dry milled to separate the hulls and germ from the endosperm fractions. At least some of the endosperm fractions are steeped in separating the starch from the gluten. The gluten is dried and the separated germ and the dried corn gluten are subjected to solvent extraction to recover corn oil.
Abstract:
HIGH QUALITY POTATO STARCH IS PRODUCED BY FINE GRINDING AND AIR CLASSIFYING CUT ABD DEHYDRATED POTATOES TO OBTAIN A STATCH-ENRICHED FRACTION AND A PROTEIN-ENRICHED FRACTION. THE STARCH-ENRICHED FRACTION IS WATER WASHED IN COUNTER CURRENT FASHION TOREMOVE PROTEIN,SUGARS, AMINO AND OTHER ORGANIC ACIDS AND OBTAIN A HIGH QUALITY POTATO STARCH CONTAINING LESS THAN 1.0% PROTEIN. THE PROTEIN-ENRICHED FRACTION FROM THE AIR CLASSIFICATION STEP IS COMBINED WITH THE WATER FROM THE COUNTER CURRENT WASHING STEP TO OBTAIN, EHEN DRIED, A PRODUCT HAVING A PROTEIN CONTENT OF ABOUT 20 TO30%. THIS RELATIVELY HIGH PROTEIN PRODUCT IS USEFUL AS A HIGH QUALITY ANIMAL FEED SUPPLEMENT.
Abstract:
A PROCESS FOR RECOVERY OF WHEAT STARCH AND GLUTEN FROM A DOUGH OF WHEAT FLOUR, AS COMPARED WITH ALL OTHER FLOUR STARCHES, BY SIMULTANEOUSLY MECHANICALLY TREATING AND SPRAY WASHING THE DOUGH WITH A STARCH ABSORBING LIQUID, THE LATTER OF WHICH IS QUICKLY CARRIED AWAY FROM THE RECOVERY REGION SO AS TO PRECLUDE AN UNDUE BUILD-UP OF WASH LIQUID, WITH THE DOUGH BEING SUBJECTED TO REPEATED SHREDDING AND CUTTING ACTIONS BY THE IMPROVED DISPOSITION AND USE OF IMPROVED SCRAPERS, SPREADING AND CUTTING MEMBERS REVOLVING WITH A ROTATABLE SHAFT EXTENDING AXIALLY WITHIN A PERFORATED SEMI-CIRCULAR TROUGH TREATMENT ZONE, WHEREBY THE GLUTEN NETWORK OF THE DOUGH MIX IS MORE EFFICIENTLY BROKEN DOWN, AND THE STARCH IS WASHED THEREFROM, AND THE REFORMED GLUTEN LUMPS RESPECTIVELY BEING RECOVERED IN DIFFERENT AREAS FOR FURTHER PREDETERMINED TREATMENT OF COMMERICAL USE.
Abstract:
A steeping tank is filled with grain and then with water. The water is then circulated continuously through the steeping tank and recirculated through a heating device and pump such that the temperature in the tank is controlled. When the temperature in the tank is uniform, and has reached a desired temperature, the water pump is closed and air is then pumped into the tank until it reaches a desired pressure. Water is then circulated downwardly through the vessel so that the grain will form a suitable globule and homogenize to become a solid substance. The water in the tank is then removed which simultaneously releases the pressure in the vessel and thereafter the grain is removed.
Abstract:
CORN AND STEEPING LIQUOR ARE CONTINUOUSLY PASSED IN OPPOSITE SENSES THROUGH A NUMBER OF REACTION VESSELS CONNECTED IN SERIES. IN EACH VESSEL, THE FLOW OF CORN AND LIQUOR IS CONCURRENT. A CORN-LIQUOR MIXTURE LEAVING EACH VESSEL IS SCREENED OUTSIDE THAT VESSEL, WHEREUPON THE SEPARATED CORN IS PASSED TO A NEXT REACTION VESSEL AND THE SEPARATED LIQUOR TO THE PRECEEDING REACTION VESSEL.
