Abstract:
A method of producing oxidized starch on a continuous basis comprisinga.) feeding a slurry of starch granules into a reactor having enough capacity to hold at least 1 hour of slurry feed on a continuous basis; b.) adding an oxidation reagent containing an elevated concentration of caustic to the reactor of Step a); c.) agitating resultant of Step b.); d.) withdrawing reacted starch slurry from the reactor of Step c.) at the same rate as the said starch slurry is added; e.) feeding a portion of said withdrawn starch slurry from Step d.) into a second reactor having enough capacity to hold at least 1 hour of said withdrawn starch slurry feed on a continuous basis; f.) adding an oxidation reagent to said second reactor of Step e.); g.) agitating said second reactor of Step f.); h.) withdrawing reacted starch slurry from said second reactor of Step g.) at the same rate as the said starch slurry is added; and i.) repeating Steps e.), f.), g.) and h.) until the oxidized starch is of desired viscosity.
