Cutting and handling doughInventor: John G. LongeneckerYear: 1980
63
In the division of a sheet of dough into blanks suitable for bak-ing, it is frequently desirable to form the dough blanks at a different time or different place than that at which the blanks are transferred to a packing container or to a tray for baking. For example, in the co-pending application of Lowell Arm-strong, Lively B. Willoughby, Rogers C. B. Morton and Har-lan How, Serial No. 143,428 filed February 10, 1950, now Pat-ent No. 2,664,- 833, dated January 5, 1954, there is disclosed a machine for forming and packing blanks of dough such as the prepared biscuits which are transported under refrigera-tion for sale in a ready-to-bake condition. In that ma chine, the sheet of dough is fed to a conveyor belt having formed there-on a plurality of upstanding, open, tubular cutters. The mov-ing conveyor passes under a roller which presses the sheet of dough down onto the cutters to form biscuit blanks within the cutters. The conveyor then carries the biscuit blanks forward into position over one or more rows of tubular cans where a group of plungers moves downwardly through the cutters to press the blanks from the cutters into the cans below. It is of course necessary in such a device to support the biscuit blanks in the cutter belt during the movement of the cutter belt from the point of contact with the roller, at which point the blanks are formed within the cutters, to the point at which the plung-ers press the blanks from the cutters into the cans.The present invention preferably utilizes a device having a plu-rality of tubular cutter elements thereon, each of said cutter el-ements having one or more discontinuities in its cutting edge so that the dough blank formed within the cutter remains con-nected to the sheet of dough by the portions of dough at the discontinuities and the blank is thereby supported pending ul-timate transfer from the device.

This machine is for the purpose of making tortillas, and its ob-ject is to produce a machine which is capable ofhandling the sticky dough known as tortilla dough for the purpose of con-tinuously producing tortillas therefrom mechanically; it will be understood by those skilled in the art that the dough from which tortillas are made is a soft colloidal mass quite sticky, and with a very slight cohesiveness. It is of a consistency some-what like that of the socalled cottage cheese.
Heretofore it has been common to produce the uncooked tortillas,- which are flat cakes 135 about 1 th of an inch in thickness and 6 to inches in width, by taking up a mass of dough and patting it out by hand, a quite laborious process. The uncooked tortilla in this condition is barely strong enough to hold together even when carefully picked up and handled.
With the present invention the tortilla dough is placed. be-tween two rollers, and means is provided to rotate the roll-ers and draw between them a layer of dough which adheres to both of them. Means is then provided to scrape the dough off one of the rollers to allow the dough strip to adhere to the oth-er roller. The individual cakes are then cut and scraped oflt, all of the excess doughbeing then returned to the dough hopper, whereby there will be discharged continuously from the ma-chine a series of well formed tortillas.
Another object of the invention is to provide means for scraping the dough of? one of the rollers first, then to scrape all of the dough oil the other roller, and finally to provide means for drawing the remaining unused quantity of dough back to the dough hopper to be used in making additional tortines.

Machine for making tortillasInventor: Ruiz Oscar F.Year: 1959

It is well-known that tortillas are thin, substantially cir-cular, ilat cakes of wheat or corn f lourrapproximately one-eighth of an inch thick and from eightl to ten inches in di-ameter. Although tortillas are a principal article of food for millions of people, the shaping oftdough into thin sheets of conventionally circular, tortilla form has largely remained va hand operation. Aside from the potentially unsanitary aspects, the hand shaping of dough into tortillas is insatis-factory because of practical and economic problems involved particularly where the production is of commercial volume. l k f At one time chunks. of dough werepatted. entirely by hand into wafers. This was very. time consuming, lfrequent-ly resulted in duced irregular shapes and jagged edges. There .have been attempts to cut out patties ,from large sheets .of dough but becauseof dough elasticity, this has not been satis-factory. This is particularly true of wheat f lour dough’which isquite elastic as compared to doughof c orn f lour. It has been more recently thepractice to pass balls of dough through rolls to obtain some pre* liminary f lattening. Then, `workers posi-tioned on opposite sides of a conveyor carryingy thelattened pieces of dough attempt to stretch each piece into desired shape. Although this somewhat reduced labor, the tortillas were little improved in shape and uniformity. For various reasons, Worker carelessness or inattention has caused con-siderable waste due to tearing, especially with wheat f lour tortillas. More significantly, hand formed tortillas are of such unusual shapes, differ# ing from theconventional circular shape, as to;cause;the tortillas to lose much of their eye ap-pea l, and salability The subject invention is believed to min-imize; the escribed problems andf to machine long sought lafter in the tortilla industry

Machines for making and baking corn tortillasInventor: Castro Flores AlbertoYear: 1961
75
This invention relates to a machine for making and baking corn tortillas or the like in a continuous sequence.
In this machine, dough” blanks formed into tortilla shape are conveyed sequentially to a first heated endless baking surface moving in a continuous path partially baking the tor-tillas at one side and then transferring them inverted onto a second heated baking surface also moving in a continuous endless path whence they are sequentially removed after the finished baking period.
A machine embodying the foregoing concept of this inven-tion comprises a baking drum presentinga cylindrical bak-ing surface rotated about a horizontal axis, upon which the shaped dough blanks are sequentially deposited at the top for baking at one side whereby they may adhere to the bak-ing surface during the further rotation of the drum. A hor-izontal circular baking pan is mounted directly underneath the horizontal baking drum for rotation about a vertical axis arranged to intersect with the horizontal axis of the baking drum. Stripping means are provided for detaching the par-tially baked tortillas from the under side of the baking drum and thereby todeposit them inverted upon the baking pan be-low in order that the tortillas may then be baked on the oppo-site side. Both the baking drum and the baking pan are driv-en and rotated at appropriate speeds in synchronism with each other so they will cooperate in producing the finished baked tortillas of the desired quality. Preferably, provision is made to have the finished tortillas discharged continuously at the margin of the pan to an end’receiving station.

Tortilla conveying system for sequentially conveying a plurality of tortillas to be warmedInventor: Ricardo GonzalezYear: 2013
79
An improved tortilla conveying system, for sequentially con-veying a plurality of tortillas to be warmed, is disclosed. The conveying system provides a stack of tortillas and automatical-ly conveys tortillas sequentially through a tortilla warmer. The tortillas are stored in a container. A dragger at least frictionally engages the top side of the top tortilla, dragging the tortilla off of the top of the container for subsequent heating by a heating element of the tortilla warmer. In some embodiments, the tor-tilla container can automatically elevate the stack of tortillas, so a top tortilla always remains exposed at the top of the con-tainer. In other embodiments, an extractor delivers the tortilla outside of the heating system once the tortilla is sufficiently warmed. The tortillas are warmed in sequence by a heating el-ement, via conduction, convection, and/or radiation. In some embodiments, various components of the conveyer are syn-chronized, via a gearbox for example.

Tortilla press apparatusInventors: Manuel J. Rubio, Alberto de la Vega, Eberhard M. LobeckYear: 1990
83
In the field of the manufacture of products such as tortillas, efforts have been increasingly directed toward reducing costs and toward increasing the speed of production. Thus, the man-ufacture of wheat tortillas has evolved over the last few years into several different means and methods of production.One such means is to die-cut the tortillas. In this means, torti-lla dough is mixed in a 300-400 pounds horizontal mixer. The dough is transferred to the feed hopper of a single or double screw extruder which extrudes a 1” thick sheet of dough onto the conveyor belt of a rolling-cutting machine. In the latter, by rolling the dough in a direction which is sideways to the direction of travel of the belt (“cross-rolling”), and lengthwise (“sheeting”), the dough ribbon is gradually reduced to an end-less sheet of dough about 30” wide. As the sheet is processed, a subtantial amount of dusting flour is used to prevent sticking of the sheet to the conveyors and the sheeter rolls.

Method and apparatus for forming and baking flat, thin discs of doughInventors: Robert M. Escamilla, Elias Escamilla, III, Elias Escamilla, Jr., Gregg E. Johnson, Rob-ert M. Arnold, Thomas TatnerYear: 1989
97
A combination pressing and initial baking system is provid-ed for converting balls of dough into thin, flat discs, such as tortillas. A box-like support structure is provided having a portion of its frontal wall open and defining a mounting for a first heated pressing plate with its dough contacting face facing downwardly and disposed at a substantial angle to the hori-zontal. A second heated pressing plate is mounted on horizon-tal pivots in the box-like support structure for pivotal move-ment between a pressing position adjacent to and parallel with the downwardly facing surface of the first pressing plate, and a feeding position where the upper ends of the pressing plates are spaced apart to permit the insertion of a ball of dough thereb-etween. Movement of the second pressing plate to its pressing position effects the pressing and initial baking of the dough in a flat disc shape. The heat input to the dough disc during press-ing determines the peripheral area and thickness of the result-ing disc. The angle of the second pressing plate relative to the horizontal is always sufficiently large to effect the gravitation-ally induced sliding of the pressed disc of dough off the second pressing plate and onto a suitable conveyor, for transport into an oven to complete the baking of the disc. The first pressing plate is pivotally mounted on the box-like support structure to permit it to be moved to a position exposing the dough con-tacting surfaces of both pressing plates for cleaning.

Machine for frying tortillasInventors: Pompa Joseph PYear: 1951
111
This invention pertains to tortillas to make edible shells for ta-cos or other similarly prepared dishes.
Hereto fore tortillas were fried by hand in deep fat and held in a position by hand as they hardened and turned crisp until they assumed the folded position desired. It is to be understood that uncooked or semi-cooked tortillas are thin, flat discs of unleavened corn or grain flour dough. In their uncooked or semi-cooked form they are soft and flexible and can be eas-ily rolled or bent. To form edible shells for tacos and other forms of similar dishes the tortillais folded diametrically un-til the two halves of each side of the fold approach each other at an acute angle. The groove and space between these halves is then stuffed with ground meat, vegetables, etc., as desired, and this product is called a taco. In order that the tortillas will maintain this folded position and to improve their taste they are fried crisp in deep fat. The tortilla then becomes an edible shell or food container, which can be used as a container for ta-cos. In order to produce these shells with a uniform shape and much faster than the hand method described, I have produced the machine hereinafter described.
The chief object of this machine is to provide mechanism for holding a number of tortillas (in the limp form) in a position so that a diametrical fold is formed with the halves on each side of this fold separated at a desired angle and immersed and fried crisp in deep fat, and thereafter drained and removed; A second object is to provide a machine for the purposes above set forth, in which the limp tortillas are held in the form de-sired between two plates, so that when they are immersed in hot fat they will not lose their shape or fioaton the surface.

Method of producing corn tortilla flourInventors: Maria Berriozabal Jose, Sollano Carlos S. F. Diez DeYear: 1955
113
This invention relates to the milling of whole corn grains and has particular reference to a process whereby a whole grain corn product, known as tortilla flour is obtained that will not turn rancid and will store perfectly over long periods of time.This application is a division of our co-pending application Se-rial Number 312,632 filed October l, 1952 and entitled Meth-od of Milling Whole Grain Kernels and Product, which latter is a continuation-in-part of our co-pending application Serial Number 172,274 filed July 6, 1950 and entitled Method of Mill-ing Whole Grain Kernels and Product.The invention is based on the discovery of a novel method of milling whole corn grains wherein the natural enzymes of the corn that cause rancidity become deadened or destroyed, re-sulting in a dry, comminuted and sterile product that is non-rancidifying in character. Corn referred to herein is Indian maize as contrasted to wheat.The word enzymes as used herein refers to the enzymes that cause rancidity including esterases such as lipase, lecithinase, etc. The enzymes are the active agents causing rancidity and when these chemical substances are ldenatured or destroyed rancid-ity is avoided. While various treatments are known to destroy enzymes, the better known processes produce undesirable ef-fects in the taste, nutrition and value of the flour. This inven-tion leaves no undesirable characteristics. The nutrition ‘of the natural oils and fats is retained as well as the vitamin content. Protein is largely unaffected, and the digestible content is ac-tually increased. The flavor of the flour and its products is not only pleasing and highly acceptable but is an improvement over flour of any type heretofore available in commerce.

Counting and stacking apparatus for torti-llas or the likeInventor: Mason Jr Cary HYear: 1968
115
This application discloses apparatus for automatically stacking tortillas or the like as delivered from a baking oven to provide even stacks of a desired number as would be packaged for con-sumer use. The apparatus counts and stacks multiple rows in-dependently of one another whereby variation in spacing of the rows as delivered from the oven is accommodate. The tortillas may be delivered from the oven to the counting and stacking mechanism by a conveyor passing through a cooling station.
Tortillas are consumed in the Southwestern region of the country much in the manner of bread, these being packaged in bags of perhaps 15 or 20 and sold in grocery stores. Tortillas are very thin, flat baked goods composed essentially of corn meal and water. After baking and while still hot, these goods are very limp and thus difficult to handle by mechanical means due to the ease of folding and wrinkling. High volume ovens have been commercially available which are able to produce many thou-sands of tortillas per hour at very low cost; but, heretofore, han-dling of the tortillas delivered from the oven on a conveyor has been entirely by hand. Labor has been needed to gather stacks of the tortillas from the conveyor output of the oven in proper numbers for packaging. Due to the high cost of labor at present, this operation has become prohibitively expensive in view of the low price for which this commodity must be sold. Accordingly, it has become necessary to mechanize this portion of the pro-duction operation.

Apparatus for making tortillas and the likeInventors: Martinez Maria NavarYear: 1975
119
This invention provides an apparatus or appliance for simul-taneously flattening and spreading flour dough patties into a set, partially or completely, cooked condition without hereto-fore required rolling of the dough. The apparatus is especially suited for home use in making of tortillas, crepes, wafers, and the like thin sheet pastries and includes a base for resting on a counter or table-top presenting an electrically heated base plate to receive the dough patty and a bar hinged to the base suspending an electrically heated lid plate to provide a lever of the second class for pressing the lid plate against the dough patty on the base plate with minimum manual effort to pro-duce a wafer sheet of the desired thinness. The manual effort is applied with a quick pressing motion on a handle which may be pivoted on the bar or may be an extension of the bar, the pressure is released to allow vapors to escape from the flat-tened patty and the lid plate may be suspended for a short time over the patty until the desired cooking is completed where-upon the handle is raised to lift the lid plate away from the base plate and the set wafer sheet is then removed to another location for cooking or cooling. The bar applies pressure to the center of the lid plate permitting this plate to slightly tilt or wobble for application of uniform pressure and the base can have a rearwardly extending foot to prevent tilting which can also be clamped to the counter or tabletop while the bar can have an overlying rearwardly extending second handle por-tion to be pressed downwardly to prevent tilting of the base.

Apparatus for pressing and baking dough discsInventor: Eugene McGuinness Year: 2011
125
A device for cooking tortilla shells evenly and to create a U-shape for tacos or bowl-shape for tostadas. For tacos, the device has one shaping member with a top, a bottom, a plu-rality of vertically disposed peaks from bottom to top, and a plurality of valleys adjacent to each of the peaks. A plurality of apertures are on each of the peaks the purpose of which is to allow full circulation of microwaves on the seated surface of a tortilla shell placed on this shaping member. A two-piece cooking device has two similarly configured rounded shap-ing members each with a flat top and a downward extending side wall. The top and side walls have a plurality of apertures. A tortilla is placed in between the two shaping members and heated in a microwave oven. Such cooking causes the tortilla shell to retain the bowl-like shape of the two shaping members.

Process of preparing grain for milling.Inventor: Joseph L WillfordYear: 1913
129
My invention consists generally in various’ steps and in the method or process hereinafter described and particularly pointed out in the claim.
The drawing, forming part of this specification, is a vertical section of certain portions of a flour mill showing an arrange-ment of machinery therein and showing an arrangement of ap-paratus for carrying out my process.
In carrymg out my invention, I take the l Patented May 13, 1913.
grain from the separator and pass it to a suitable scourer A, from which it is pased mto aheating tank B, where it is subject-ed to, a ,current of air of high temperature, and lsheld there-in until it has reached the tem- I desired which Ihave usually found 140 degfees Fahrenheit. The c ;;;a1r 1s prefera 1y sup-plied through a radiatorC, being drawn. through the casing of theradiatorby a suitable fan D. From the fan D, .the heated air is driven to the pipe E and the branch pipes E and E and it may also be driven to any additional number of The air from the-branch pipe E enters the grain heating and conditionln tank B, and, while the grain is held thereln, the heated air from this pipe, passing into the casing, thorou hly heats the grain and raises it prefer-a ly to a temperature of about 140 degrees. From the heating tank B, the grain passes into a spiral or other suit-able conveyer F, and in order that the grainmay be properly treated while in this conveyer, a branch pipe E is preferably provided in connection with the pipe E which conducts the hot air to the head of ‘the’conveyer. I also preferably provide means, such as a water tank F and a conductor F for supplying water to the head end of the conveyer .F, so that said grainis moistened or wet as it passes through the conveyer F.

Cooking vesselInventor: Benjamin F FergusonYear: 1910
131
This invention relates to a cooking vessel, and particularly to a broiler and toaster, the object in view being to provide a ves-sel which may be employed either for toasting bread or broil-ing meats without emission of odors and which when used for broiling will prevent waste of the meat juices and enable the meat to be turned to cook it thoroughly from both sides and at the same time automatically baste .the meat so as to maint-ain it in a juicy condition.A further object of the invention is to provide a device of this character which may be employed upon any kind of cook stove or open tire and which may be easily cleansed and manufac-tured and sold at a low cost.The invention consists of the features of construction, com-bination and arrangement of parts hereinafter fully described and claimed, reference being had to the accompanying draw-ing, in which Fignre 1 is a perspective view of a broiler or toast-er embodying my invention as closed for use. Fig. 2 is a vertical longitudinal section of the same with the parts arranged in po-sition to be closed or disconnected. Fig. 3 is a perspective view of one of the grates. Fig. 4 is a fragmentary front elevation of the closed device. Fig. 5 is a section on line of Fig. 4.Referring to the drawing, my improved broiler or toaster com-prises a preferably cylindrical pan or receptacle composed of two counterparts or duplicate sections 1 and 2, each having an open side. These sections are formed of cast or stamped metal` and each is provided at its rear with a handle 3. To the front of one of the sections, diamet rically opposite the handle, is fixed a keeper plate 4 having a receiving slot 5, and similarly applied to the other section is a catch plate 6 having a hooked tongue 7 to engage said slot, whereby interengaging members are pro-vided to enable the sections.
