Abstract
This invention relates to methods and apparatus for processing grain, such as corn, into flour and dough useful in making foodstuff products, such as tacos, tortillas, corn chips, etc. In one embodiment, atmospheric pre-heating of the grain with consequent cracking of the hull is combined with the softening effects of a lime water spray to deliver partially cooled grain in a comparatively dry state to a mill for efficient pulverization, following which it is made into a dough which is finally cooked and formed into the desired end product.
Claims6
A method of forming foodstuff materials from corn comprising the steps of
- heating corn with the hull thereon and while in the unwetted state to a hull temperature of 135.degree. C.-150.degree. C. so as to cause cracking of the corn hulls,
- quenching said heated corn with lime water to adjust the moisture content of the grain to a range of about 18% to about 27%.
- grinding said corn into particles,
- segregating out particles according to desired size,
- combining selected particles with a sufficient amount of lime water to form dough therefrom, and
- heating said dough so as to cook same.
