METHOD OF MAKING FLAT EDIBLE USING A COMPACT APPARATUS

FIELD OF INVENTION

This disclosure relates generally to a method of making flat edibles like tortilla, crepes, chapatis, rotis, pita breads etc., using a compact apparatus.

BACKGROUND OF INVENTION

Invention and use of devices to aid in food production is known to public. Currently available is a whole array of automated mixing, flattening, and cooking devices designed to simplify a production process of flat dough products such as Tortillas, Puri, Papadam and Chapati. An attempt to make a single semi-automatic device suitable for industrial use by Chandulal Patel in U.S. Pat. No. 5,630,358. However, as per Chandulal Patel disclosure users needed to add measured quantities of ingredients to the device. The device then mixes the dough, flattens it, and puts it on a conveyor belt for cooking. Adding right quantities of ingredients of right measure to the device may not have been possible by an unskilled user or a user who had little knowledge of making edibles. In addition, the device as described in Chandulal Patel did not have capacity for storing excess ingredients. Furthermore, the device did not have a corrective mechanism if the user adds ingredients in incorrect proportion. Furthermore, the device as described in Chandulal Patel was bulky with a conveyer and a carousel that was at least twice the size of the edibles being made. Furthermore, the device used pneumatics for pressurizing rendering the device expensive and bulky for home use.

SUMMARY OF INVENTION

This disclosure describes about a method and a series of steps that is fully automated using a compact and portable apparatus. The method described herein may be used to produce flatbreads, tortillas, rotis, parathas, crepes, chapatis, and numerous other dough based food products. The method with a series of steps is used for dispensing ingredients, mix the ingredients, kneading the mixture, flattening the kneaded mixture, shaping the flattened kneaded mixture and cooking the mixture into a food product based on input obtained from internal monitoring sensors and/or inputs given by the user. The apparatus may be capable of producing either a single product at a time or simultaneously processing one product while other is being cooked. The apparatus may not require continuous monitoring by the user as the apparatus is configured to generate alert for the user if intervention is required. The apparatus may include storage and dispensing unit, a mixing and kneading unit, a vertical transfer unit, a horizontal transfer unit, a pressing and heating unit, and a control unit. The control unit may include a processor which can be preprogrammed or controlled based on user input. The user may provide input through a control panel to generate an edible of desired size, thickness, at a specific cooking temperature, in a specified time, and a number of edibles to be produced. Based on the user input, the control unit configures the storage and dispensing unit to dispense appropriate quantities of ingredients for generating a first edible. A mixing and kneading unit of the apparatus may be configured to mix the ingredients and to knead the mixed ingredients into dough.

A shape of the blade of the mixing and kneading unit as described in the disclosure ensures a good consistency for the dough, and prevents sticking. A vertical transfer unit of the apparatus may be then configured to transfer the dough to a platen unit of the apparatus. The ring shaped feature (optional) in a vertical transfer unit of the apparatus may remove any dough sticking to the sides of the mixing and kneading unit. Alternatively, a hot water may be used for cleaning the mixing and kneading unit. A horizontal transfer unit of the apparatus may be configured to move the dough to a platen unit for flattening and cooking.

The platen unit may be configured to flatten and cook the dough. The platen unit may include an upper platen and a lower platen configured to move relative to each other. These platens may be pre-heated to an appropriate temperature or at temperatures input by the user. The upper platen may be moved towards the lower platen to flatten the dough into a flat edible with thickness as input by user, using a spacer or as preprogrammed. The upper platen may be moved away from the lower platen and is held at an appropriate distance that is programmed into the apparatus. The upper platen may be held at an appropriate distance for a particular period to bake/cook the product. After the edible is sufficiently cooked, the horizontal transfer unit may be configured to push the edible out of the platen unit into a receptacle (tray) designed thereof.

A method, system and an apparatus of a compact appliance for making flat edibles is disclosed. In one aspect, an apparatus includes a first dispenser comprising a liquid material, and a second dispenser comprising a grounded edible material. The method also includes a consistency module to obtain dough of optimal consistency through at least one of an automatic adjustment and manual adjustment of an admixture of the liquid material and the grounded edible material surrounding a blade of the apparatus based on an electrical property associated with a rotation of the blade.

In another aspect, a method includes making a flat edible material. The method also includes mixing a grounded edible material and a liquid material to make dough. In addition, the method includes optimizing an input of the grounded edible material and the liquid material to obtain an optimal consistency of the dough based on a change in current read as a resistance caused by mixing the grounded edible material and liquid material while forming the dough. The method also includes flattening the dough to make the flat edible with a pressure mechanism between an upper platen and a lower platen and cooking the flattened dough.

In yet another aspect, an apparatus includes a modular unit to make a flat edible. The apparatus includes a first dispenser, a second dispenser, a mixing and kneading bowl, a pressure unit, a horizontal transfer unit, an upper platen, a lower platen, and a processor.

The apparatus described herein is a single machine that can store, dispense, mix, knead, flatten and cook a flat food product, thereby eliminating the need for several pieces of equipment or for any user intervention for making flat edibles. In addition, the apparatus described herein may minimize user intervention by having a self-clean mode that invokes a cleaning operation in the apparatus to perform cleaning operation after producing a batch of edibles. Furthermore, the apparatus described herein may be designed as a compact, portable, and counter-top appliance for making flat edibles. Furthermore, the apparatus eliminates a need of user to pre-measure quantities of ingredients to be added into the apparatus for the process of making the said flat edibles. A storage and dispensing unit of the apparatus may be designed to store a large or small quantity of ingredients as desired by the user. In addition, the apparatus may be programmed to dispense programmed quantities of ingredients required for making the food product. Also, the apparatus described herein may be designed to allow storage of raw materials needed for producing flat edibles, so that the apparatus may be used as a stand-alone unit.

The apparatus described herein may be designed to process ingredients and produce cooked edible simultaneously through mixing and kneading in a mixing and kneading unit to produce a dough while, cooking a flattened dough in a pressing and heating unit. The apparatus described herein may be designed to enable the user to control a quantity of edible production, quality, cooking temperature, cooking time, consistency, thickness, size and such other parameters of the product (e.g., edible) through the control panel for providing suitable values to the apparatus. In addition, the apparatus described herein enables the user to change the values as desired through the control panel provided in the apparatus.

FIG. 13 is a process flow of generating a single flat edible at a time 1300 using the apparatus 100, according to one or more embodiments. In operation 1301, the apparatus 100 may be turned on. In operation 1303, solid (e.g., flour) and liquid (e.g., water, oil) may be added into respective dispensers. In one or more embodiments, an input may be obtained from the user such as number of flat edibles required, size of the flat edible (e.g., thickness), temperature, type and/or brand of flour etc. In one or more embodiments, quantity of ingredients may be checked by means of sensors (e.g., strain gauge, etc.) in the dispenser to determine sufficiency of ingredients to generate number of flat edibles as requested by user. If the quantity is determined to be less for the generating number of flat edible materials, then an alert may be generated and shortage may be indicated at the output unit of the control panel 128. Furthermore, in one or more embodiments, the platens may be heated to a temperature set by the user. Furthermore, the transfer base 144 may be raised (e.g., using the vertical transfer unit 114) from an initial position to form a bottom of the kneading container 122.

The amount of ingredients to generate a single flat edible may be calculated based on type and/or brand of flour (proportion of flour to water for optimal dough formation is function of composition of flour material which changes with type and/or brand of flour used) either by user input or by default values stored in processor and in operation 1305, a controlled amount of solid ingredient and the liquid ingredient may be dispensed into the mixing and kneading container 122. In one or more embodiments, the amount of ingredients may be calculated based on size and thickness of the flat edible input by the user. Mixing operation may be performed to mix the ingredients. In one or more embodiments, the motor 140 may be activated by the motor control module 908 through the processor 132 to perform mixing and kneading operation (e.g., using the segmented blade 406). Based on input obtained from the resistance measurement module 905, the speed of the segmented blade 406 may be controlled (e.g., using the blade rotation control module 919) by controlling the motor 140 based on pre-programmed time for optimal mixing and kneading of the ingredients. Alternatively, data obtained from various optional sensors like actuator current sensor, torque sensor, etc. positioned in the mixing and kneading unit 400 may be used as a feedback to control the speed of the segmented blade 406.

In operation 1306, kneading may be performed. Also, in one or more embodiments, dough may also be prepared in a preprogrammed mode. In one or more embodiments, in preprogrammed mode, the values for blade rotation power consumption/speed etc., timing and sequence of moving transfer base 144 relative to mixing and kneading unit 400 and the segmented blade 406 rotation may be obtained from a custom mode stored in the memory of the apparatus 100.

In operation 1307, consistency of the dough may be determined by measuring electrical reading (e.g., electrical reading while kneading dough of optimal consistency may be taken at testing stage of product). In operation 1309, mixing of ingredients may be adjusted (e.g., quantity to generate an optimal dough may be input into the apparatus 100) based on consistency data. In operation 1313, the kneaded dough may be transferred from transfer base 144 to lower platen 106 by the transfer sweeper 118 controlled by the horizontal transfer unit 120. In one or more embodiments, the kneaded dough may be dispensed on the transfer base 144 from the kneading container 122. In one or more embodiments, the motion of the segmented blade 406 may be stopped before, during or after the downward motion of the transfer base 144.

In operation 1306, kneading may be performed in the mixing and kneading container 122. In operation 1307, consistency of the dough may be determined by measuring electrical reading (e.g., electrical reading while kneading dough of optimal consistency may be taken at testing stage of product). In operation 1309, ingredients to be mixed may be adjusted (e.g., quantity to generate an optimal dough may be input into the apparatus 100) based on consistency data. In operation 1313, the kneaded dough may be transferred to a transfer base 144 which is lowered (e.g., by the vertical transfer unit 114) and then transferred to a lower platen 106 by a transfer sweeper 118. Once the dough is dispensed, the transfer base 144 may be moved to a pre-determined position (e.g., by the vertical transfer unit 114) to form a base of mixing and kneading container 122. Furthermore, operation 1305 may be initiated to generate dough for one serving of flat edible simultaneously while operation 1315 is being performed. In operation 1315, the dough for one serving of flat edible may be flattened. In operation 1317, the flattened dough for one serving of flat edible may be cooked as flat edible material. In operation 1319, the cooked flattened edible material may be dispensed. As soon as one cooked flat edible is dispensed on the tray 130 by operation 1319, dough which was prepared simultaneously is ready to be dispensed onto the lower platen unit by operation 1313, The process may be continued until all the solid and liquid in the dispensers are emptied or the number of flat edibles based on user input are dispensed. Once the solid and liquid are emptied, the operation 1303 may be initiated.

In one or more embodiments, phase I 1602 may be called as wet phase. In phase II 1604, the resistance of the segmented blade 406 for rotation due to formation of dough may be measured using the resistance measurement module 905 (e.g., in automatic adjustment mode). Furthermore, required power may be supplied to the segmented blade 406 through the blade rotation control module 919 to ensure sufficient torque to the segmented blade 406 to continue generation of a dough (in semi-solid state) of optimal consistency 1614. In one or more embodiments, the phase II 1604 may be called as semi-solid phase. In phase III 1608, the mixing operation is continued until crumbly dough 1612 is generated. In one or more embodiments, phase III 1608 may be called as dry stage.

Power consumption at regular intervals may be recorded through the electricity usage reading module 903. In one or more embodiments, there may be variable power consumption by the motor 140 at different stage of formation of dough (e.g., due to variable resistance in rotation of the motor 140 while kneading the dough). Based on power consumption (e.g., based on resistance offered by the rotation of motor 140) the processor 132 may control the peristaltic pump 702 or a dispenser motor 1206 of the dispenser to release calculated quantity of ingredients to compensate any shortage or to balance any additional quantity in the mixing and kneading container 122. In alternate embodiments, generation of optimal consistency of the dough may also be controlled manually (e.g., in manual adjustment mode) by the user based on preconfigured sequence related to type and/or brand of flour known to processor (e.g., customized).

FIG. 17 is a pictorial process flow 1508B illustrating continuation of FIG. 16 illustrating additional operations for generation of dough, according to one or more embodiments. Further to operations in FIG. 16, kneading process is initiated to generate a dough of optimal consistency 1602. The resistance caused while kneading may be sensed and observed by the resistance measurement module 905. The blade rotation control module 919 may invoke the motor control module 908 to supply for more power to maintain necessary torque. In addition, the power consumed by the motor 140 may be observed by the electricity usage reading module 903 and power through the motor control module 908 may be provided to ensure sufficient power supply to maintain torque. The process may be continued till dough of optimal consistency is generated.

Alternatively, in manual mode (e.g., manual adjustment), the kneading operation may be continued based on preconfigured timing and sequence configured in the custom mode based on type and/or brand of flour. The dough thus prepared may be transferred to the platen unit. FIG. 18 illustrates the flattening operation 1510 of FIG. 15, according to one or more embodiments. The dough for one serving of flat edible may be flattened through the flattening operation 1510 using the platens of the platen unit. The spacer 306 may be used in between the upper platen 108 and the lower platen 106 to generate a flat edible with desired thickness.

In one or more embodiments, the cooking process as described herein may constitute of several steps. In one or more embodiments, the upper platen 108 may be heated to a temperature higher than as compared to the temperature of the lower platen 106 to ensure sufficient cooking of the edible. The upper platen 108 may be first moved close to the lower platen 106 initially for flattening the dough for one serving of flat edible based on the input provided by the user (e.g., through the user interface) or based on pre-programmed sequence.

In a further step, the upper platen 108 after a prescribed time may be moved away from the flattened dough for a specific distance to continue cooking process through radiation of heat. Further, in next step, the upper platen 108 may be moved towards the lower platen 106 to make contact with the cooking flattened dough. The upper platen 108 may be moved one or more times towards and against the cooking flattened dough to ensure proper cooking of the flattened dough. In one or more embodiments, second contact movement as described above may emulate a puffing process (e.g., for soft edible product such as chapati, roti, tortilla, etc.) of the edible as performed in conventional cooking process (e.g., as in manual cooking). The contact movements as described above may also serve for cooking an upper layer of the edible (e.g., for both soft edible like chapati and hard edible like biscuit).

The aforementioned steps may eliminate a need of flipping process of the edible while in cooking to ensure proper cooking as compared to conventional cooking process. The upper platen 108 is heated to a temperature higher than as compared to the temperature of the lower platen 106 to ensure sufficient cooking of the edible as the upper platen 108 does not have contact with the edible all the time. Other methods for cooking the flattened dough may be used as well.

In one or more embodiments, the dispensers as described in the apparatus 100 may be replaced by attachments connecting to pipelines, enabling a continuous input of ingredients, thereby enabling a continuous production process. Also, in one or more embodiments, mixture of ingredients may be used in a dispenser instead of single ingredient. Also, in one or more embodiments, the functioning of the storage/dispensing unit and the mixing and kneading unit 400 may be intermixed with each other for production of better dough. For example, the motor 140 may be started before dispensing of the ingredients, or ingredients may be dispensed at intermediate times during the operation of the motor 140. In one or more embodiments, the aforementioned sequence may be programmed into the apparatus 100 or may be initiated through the control panel 128 based on inputs obtained from the mixing and kneading unit 400 during operation or may be reading obtained from the consistency module 922. Also, in one or more embodiments, the lower platen 106 may be replaced with a rotating carousel with multiple platens, or a single rotating disc. This feature may allow production of multiple edible products in parallel, with few edible products being pressed while another edible product is being prepared. This embodiment may require multiple instances of the horizontal transfer unit 120. Also, in one or more embodiments, the upper platen 108 and the lower platen 106 may be formed in different shapes instead of the flat surfaces as depicted in the aforementioned embodiments. For example, the platens may have circular depressions in them to form dough in a shape of a bagel or pizza crusts or other edibles which have a physical form similar to flat edibles. Alternately, the pressing mechanism including the upper platen 108, the support bars 312 and upper weight 310 may be replaced by a rolling pin system for flattening the dough. In one or more embodiments, the apparatus 100 is fully automated, compact, and portable appliance.

The apparatus 100 described herein is compact and may include all the units as described herein under the apparatus 100. Although the present embodiments have been described with reference to specific example embodiments, it will be evident that various modifications and changes may be made to these embodiments without departing from the broader spirit and scope of the various embodiments. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
