Kiln-dried corn meal

Drying corn in a pan-kiln (patents by 1812, 1816; British patent 1824 at left) for corn meal was said to have been invented at the Lea owned Brandywine Mills (Wilmington, Del).  George Ellicott's daughter Elizabeth Ellicott Lea married Thomas Lea, the son of the founder.

1880
"It was in the Brandywine Mills that Kiln-dried corn meal was first invented and produced, more than half a century ago, since which time it has constituted a specialty of this house, and forms a very important item of its trade, immense quantities being annually shipped to the various West Indian ports."
Industries of Delaware: Historical and Descriptive Review.  1880

Laws were also framed in the several States prior to the adoption of the Federal Constitution regulating intercourse with foreign nations. The laws bearing upon this matter were much more stringent in Pennsylvania than in Delaware, and consequently a large shipping trade sprang up between Wilmington and the West Indies Corn-meal was in great demand in this trade and was shipped in large quantities, but it invariably spoiled before reaching destination. It was then suggested at the Brandywine Mills that the corn be dried before grinding. 

An experiment was tried by drying some in a malt-house, and being found to answer, drying-houses, similar to malt houses, were constructed alongside the mills, with brick floors and heated by flues and turned over with shovels every half-hour. In this primitive way about two hundred bushels could be dried every twenty-four hours. 

The proprietors of these mills, anxious to improve their facilities, purchased in 1812, of John R. Parry, of Montgomery County, Pennsylvania, for eighty dollars, the right to construct and use his “patent machine for kiln-drying corn, etc.” but whether it was found a success is not known. 

About 1816 one Crook, of New Hope, Pennsylvania, invented the pan-kiln, which, until lately, was used very much as originally constructed; and even now, though large quantities are manufactured in other parts of the country, the Brandywine meal is largely preferred by shippers.

1847
Messrs. Tattnal and Lea of the Brandywine mills have just informed me that they have complied with my request and sent to their agents, Messrs. Allen and Paxson, New-York, a small specimen of white kiln-dried corn meal, which is at your service to exhibit to the "Farmers' Club," or to experiment with as a Marylander so well knows how, and thus enable him to testify to its merits as an article suitable to the English market, under the favorable prospect of an increased corn trade with that country. The sample sent is by no means as good as may be manufactured when several hundred or thousand bushels are kiln-dried together, as they now do the yellow corn.

The enclosed letter from Mr. James Canby, whose experience reaches to half a century, will not be without its interest at your discussions on corn and corn meal at the “Institute." The long-standing celebrity of the Brandywine mills in the manufacture of flour has not been surpassed by their success, and, indeed, almost monopoly of the kiln-dried com meal business—for now upward of fifty years.

During the whole of this period, except to the West Indies, and principally in the shape of kiln-dried meal, but comparatively very little of this great and native grain has been exported from the United States to other countries. As a new era is, however, opening upon us, and a requisition is about to be made upon the inexhaustible supplies of Indian Corn which can be produced in our country, every fact in relation to the best kinds, and modes of manufacture adapting it for transportation, are sought after with interest.

The facts I have been enabled to collect principally through the politeness of the Brandywine millers, agreeably to your request, are cheerfully communicated. Those disposed to investigate the numerous varieties of maize grown in our country, can readily be gratified by referring to Emerson's American Encyclopaedia, Lorraine's Husbandry, and the pamphlet of Peter A. Brown, Esq. of Philadelphia, on this particular subject. The only reference to varieties necessary to be made in this communication, is to the white and yellow corn of commerce; the best of which will of course be selected to suit the market and taste of the consumer.

Early in the history of our country, you are aware that both public and private attention were directed to the vast importance of this grain—that repeated attempts to rear it in countries uncongenial to its growth have failed, and shipping it abroad in bulk has been nearly abandoned, for the reasons assigned in Mr. Canby's letter; for when it cannot be safely conveyed from New-Orleans to New-York and Boston without heating and injury, it cannot be exported to Liverpool and London, as one or more cargoes recently tried on account of the English government has fully tested.

Experience therefore teaches, so far as yet ascertained, that Corn intended for exportation must be kiln-dried if not manufactured in the country which produces it. This process, I am informed, was attempted in Connecticut at the close of the Revolution, and about the same time at the Brandywine mills—the Connecticut millers using the white corn, and producing an inferior article of meal, owing to want of skill in preparing it and defects in the construction of the kiln. The Brandywine millers perfected their kiln and adopted the yellow corn by way of distinction, more for the purpose of signalizing their brand, than any supposed superiority over the white. From greater proficiency in kiln-drying and manufacturing Meal, they soon engrossed the West India markets for their yellow meal, and thus induced our farmers to grow so extensively here the yellow corn. This fact is not generally known, and is interesting in the history of kiln-dried corn meal.

At the several mills on the Brandywine, there are annually thus dried and ground some half-million bushels of corn. It is packed into hogsheads and barrels, and is shipped principally to the West Indies—keeping for a long period perfectly good, and does not appear to be deprived of any of its nutritive properties by having been subjected to heat. Chemical analysis will test this, and can decide the question which of the two is to be preferred—white or yellow corn.

The Corn Mill is five stories in height and fifty-five feet square. It is provided with two sets of rolls and one pair of mill-stones. The “Jog” mill, seventy feet square and three stories high, has four sets of rolls. The two mills just described are used in the production of the “Brandywine Kiln-Dried Corn Meal.”

The “B” Mill, the most recently erected, five stories high, and eighty-six feet by seventy-two feet in dimensions, is devoted exclusively to the manufacture of fancy articles of white and yellow corn specialties, such as hominy, grits, granulated corn-meal, corn flour, etc., and is one of the most complete in the country. This large mill is equipped with eleven sets of rolls, and with all of the latest adjuncts for scientific milling, and the convenient and expeditious handling of grain. In addition, it has an automatic hoisting-machine which lifts the full barrels from the lower floor and delivers them into the cars.

These mills have a storage capacity of seventyfive thousand bushels of wheat, and about one hundred and twenty-five thousand bushels of corn, besides ample storage capacity for flour, meal, empty barrels and packages necessary to the business. At these mills about two thousand five hundred barrels of flour and corn meal are manufactured each day, besides the specialties mentioned above. The brands of flour made at these mills are known as “ Best,” “ Clifton Mill FFF,” “ Poutaxat,” “Kirk wood,” “Avalon,” “Occidental” and " Southern Extra,” and the corn meal “ Lea's Brandywine Kiln-dried Corn Meal.”

KILN DRIED CORN MEAL.  1831
We know not whether the manufacturing of Kiln Dried Corn Meal is attended to in this country; but, whether it is or is not, the following instructions from the Journal of Commerce, may be of some use:

Kiln dried meal must be made of the best yellow corn; while would not ‘sell. Hogsheads should be made of the best seasoned white oak stuff, 4 feet 5 ½ inches long, and be 2 feet 3 ½ inches across the head. Four iron hoops on each hhd. The rest of the hoops strong, smooth, hickory. The hhds. must be made tight, as they are sold for rum hhds. in the West Indies—the only market for them.

The corn is dried in a large sheet-iron cylinder, or in pans, (put in motion by the mill) in a heated air-chamber of brick. The meal is sifted; the cloth as open as the common middlings cloth in a sup-reel, and about 4 feet long.

The weight in each hhd. 800lbs. and the hhd. must be branded with the name of the maker and kiln dried corn meal, ‘No. 1. 80016.9. The meal must be of a bright yellow, and smell strongly of the kiln, or it will not pass inspection. Ten hhds. per day is moderate work for a good pair of burrs and a good kiln, sixteen bushels of good corn will make a hhd.—old corn less. Ten to 12.000 hhds. are in New-York yearly for the West Indies.

It would not be safe for a new hand to construct a kiln, without the presence of an experienced workman who has put them up. The sheet iron pans are better than the cylinders.

The price in New-York varies from $13 to 15 through the year, when corn is plenty. The cost of a complete kiln with pans, is $400 to 3500.

The vegetating principle must be entirely destroyed, and the point of sufficient dryness can be easily ascertained by the smell of the meal while grinding. Great pains must be taken in making the hhds. Well and of stuff lsng seasoned; or the meal will make them shrink so much that they will fall to pieces before they reach the market.
