Embodiments of this invention include methods and apparatus for the continous production of acid-pressure precooked and partially debranned corn flour for arepas, tortillas, and snacks, may be produced, by a rapid pressure precooking with a sodium metabisulfite, or sodium hydrogen sulfite or sodium sulfite solution as a food processing aid so to effect a partial hydrolysis of insoluble fiber and protein along with a controlled gelatinization and denaturation, reduced kernel washing and corn solid loss into wastewater, stabilization of the moisture content to a desired optimum level for grinding, milling and drying the preconditionned kernel to produce a partial cooking, cooling and drying the dry-ground particle, separating and recovering the fine grind so produced from the coarser grind while the latter is further aspirated to partially remove a corn bran fraction for feed or integral flour, remilling the isolated coarser grind and further sieving it to obtain an instant corn flour for arepa, and admixing only a fine flour with lime to produce a limed-corn, or masa, flour for tortillas and snack foods. |
