The invention provides a tortilla-making machine 1 with continuous metal griddles or strips heated by high-temperature air for producing nixtamalized-maize-dough tortillas, different types of totopos and fried foods, which comprises: a supply and shaping module 2 with a hopper 5 mounted on a head 6 that includes a receiving roller 9, a rolling roller 10 and a shaping or cutting roller 11 with spindles 9A, 10A and 11A, respectively, which are actuated by a motor 12, for receiving the dough from the hopper 5, rolling it and cutting it into the desired shape, and a conveyor 17 actuated by a conveyor roller for conveying the rolled, cut dough to a product-cooking module 3 that has three endless metal griddles or strips 20, 21 and 22 that have rollers 20C, 21C and 22C actuated by a motor 23, the strips or griddles 21 and 22 only having a non-stick covering on their outer surface in order to prevent the product sticking to them, and a calorific-energy supply module 4 that includes a heater 31 and a fan 31A whereby hot air is drawn through an inlet conduit 28 with three outlets, which enters into contact, by means of the air-retaining sections 30, with the inner surfaces of the strips or griddles 20, 21 and 22 in order to cook the product, the air already used by said strips or griddles 20, 21 and 22, now cooler, is recovered via the inlets of the air-extraction conduit 28A, which has, in its lower part, inside same, a conduit 28B that conveys fresh, oxygen-rich air, said fresh, oxygen-rich air being heated up by the passage of the recovered hot air and being sent to the heater 31 that has a gas inlet 32 and a fan 31A for circulating the hot air via the hot-air inlet conduit 28 towards the endless metal griddles or strips 20, 21 and 22. The recovered hot air is conveyed via a tube 28C towards the outside. In order to produce flour tortillas, use is made, instead of the supply and shaping module 2, of a supply and shaping module 2' that comprises: a wheat-flour-dough-receiving hopper 5' of inverted pyramidal configuration, with a rectangular base and cylindrical bottom, mounted with a worm-type extruder 5'' that supplies a head of injectors 6' with the required quantity of wheat-flour dough, this supply and shaping module 2' comprising, at its start, a sieve C1 that deposits a layer of wheat flour on a conveyor belt B. After the injectors 6' there is a further sieve C2 that deposits another layer of wheat flour onto the dough, extruded in the form of small pellets, ready to enter a press PR for forming the wheat-flour tortilla and which contains a working plate P with non-stick material. Also, this supply and shaping module 2' has an open-mesh strip 17' for removing the excess wheat flour from the tortilla and conveying the product formed to the cooking strips or griddles 20, 21 and 22 in order for it to be cooked. The finished product is extracted via the strip or griddle 22. |
