DESC:FIELD OF INVENTION
[0001] The present disclosure relates to food processing devices. More particularly, the present disclosure relates to a food processing device for making flat edibles like rotis, tortilla, crepes, chapatis, etc.
BACKGROUND OF THE INVENTION
[0002] Food processing devices are widely used in a food industry for kneading and rolling dough to produce a variety of edibles, such as breads, pastries, flatbreads, etc. Typical food processing device for cooking roti involves creating a large batch of dough by mixing and kneading one or more ingredients. From the large batch of dough, a small bit of dough is removed and rolled flat with a rolling pin on a flat surface. In an example, a kneading machine is used to mix and develop gluten structures in a dough, while a rolling system or machine is used to flatten the dough. Thus, existing food processing devices contribute to additional equipment for multiple processes (kneading and rolling), manual intervention, and production downtime. As a result, the food processing devices are inefficient in terms of space utilization, operational flexibility, and overall productivity, particularly in environments that require frequent changes between different dough types and processing methods.

DETAILED DESCRIPTION
[0015] Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Generally, corresponding reference numbers may be used throughout the drawings to refer to the same or corresponding parts/portions, e.g., 1, 1`, 1```, 101a, 101b, and 101c could refer to one or more comparable components used in the same and/or different depicted embodiments.
[0016] Referring to FIG. 1, an exemplary food processing device 100 is shown and described. The food processing device 100 may be used, e.g., by one or more personnel or a human user, in households and commercial settings to process one or more food items (not shown). Term ‘process’, as used in the present disclosure, may correspond to or include a way of grinding, mixing, stirring, kneading, emulsifying, whipping, cutting, shredding, grating, or beating the one or more food items using the food processing device 100. Further, phrase ‘food’ or ‘edible material’, as used in the present disclosure, may correspond to or include, but not limited to, grains, spices, nuts, liquids, flour, and other edible materials commonly used in culinary applications. Further, phrase ‘flat edibles’, as used in the present disclosure, may correspond to rotis, tortilla, crepes, chapatis, or alike. Accordingly, the user may process the one or more food items using the food processing device 100 to create a desired food product of his/her/their choice. In an example, the user may put the one or more food items in a suitable container 110 that may be coupled with the food processing device 100 to process the food items. The food processing device 100 may include various components that may cooperate to process the one or more food items. It is to be understood that the term ‘food processing device’ is to be interpreted broadly as including not only self-contained units, but also appliances, such as blenders, mixer grinders, food processors, stand mixers, juicer mixers, wet grinders, etc. that may be integrated with other systems for the performance of other functions, etc.
[0017] Referring to FIG. 1, an exemplary exploded perspective view of a food processing device 100 is shown and described. The food processing device 100 includes several components and assemblies to various operations. In an exemplary embodiment, the food processing device 100 may be configured to process one or more ingredients including, but not limited to, an edible material and a liquid material, to perform kneading operation and/or rolling operation thereon. In some embodiments, the food processing device 100 may include a first section 104, a second section 114 adjacently position to the first section 104, and a bottom cover 106. The first section 104 may include a motor 108 for powering the kneading operation and the rolling operation. For example, the motor 108 includes an output shaft 108a configured to produce a first rotational motion at a first revolutions per minute (RPM) value. The second section 114 may include a pulley 118 configured to be driven by the motor via a belt B. For example, the motor 108 may be rotatably engaged with the pulley 118 via the belt B and configured to drive the pulley 118 with the first rotational motion at the first RPM value via the belt B. Upon receiving the first rotational motion from the motor 108, the pulley 118 may be configured to produce a second rotational motion at a second RPM value. In some embodiments, the output shaft 108a of the motor 108 defines a first diameter and the pulley 118 defines a second diameter greater than the first diameter of the output shaft 108a. Accordingly, the second RPM value of the second rotational motion produced by the pulley 118 may be different than the first RPM value of the first rotational motion produced by the motor 108. In an example, in case when the first diameter is smaller than the second diameter, the second RPM value of the second rotational motion produced by the pulley 118 may be lower than the first RPM value of the first rotational motion produced by the motor 108. In some exemplary embodiments, the motor 108 may be a direct current (DC) motor to produce the first rotational motion at the first RPM value ranging between 2000 RPM to 20000 RPM. In some embodiments, one or more gears or pulleys and combination thereof, may be used to produce the second rotational motion at the second RPM instead a single pulley 118. In some exemplary embodiments, the pulley 118 may be configures to produce the second rotational motion at the second RPM value ranging between 200 RPM to 2500 RPM.
[0018] In some embodiments, the second section 114 may include a driveshaft 122 operably coupled with the pulley 118 via a first bearing device 120. Accordingly, the driveshaft 122 may be operably coupled with the output shaft 108a of the motor 108. Thus, the motor 108 providing the first rotational motion to the pulley 118, may get converted into to the second rotational motion to drive the driveshaft 122 at a first rotational speed. In some embodiments, the first bearing device 120 may be coupled with the bottom cover 106 of the food processing device 100 via one or more first fastening means F1. In some embodiment, the second section 114 may include a platform 124 defining an opening 124a to receive the driveshaft 122. The platform 124 may be coupled with the second section 114 by extending one or more coupling means 126 to corresponding holes 126a present on the second section 114.
[0019] In some embodiments, the food processing device 100 may include a kneading assembly 128 to perform the kneading operation. In this regard, the kneading assembly 128 may be configured to mix the edible material with the liquid material (not shown). For example, the kneading assembly 128 may include a container 130 and a blade 132 provided within the container 130. The blade 132 may be couplable with the driveshaft 122 to mix the edible material with the liquid material and knead a dough for making a kneaded ingredient (not shown). In other words, upon receiving the edible material and the liquid material, the kneading assembly 128 may be configured to knead the dough for making the kneaded ingredient. In an exemplary embodiment, the edible material may be used in the kneading assembly 128 to prepare the kneaded ingredient, the edible material may include, but not limited to, flour varieties, such as wheat flour, refined flour (maida), corn flour, or millet flour, along with optional additives like salt, sugar, baking powder, or spices for flavouring. Further, the liquid materials that facilitate the kneading process may include, but not limited to, water, milk, edible oils, melted butter, or other liquid ingredients, such as yogurt or egg mixtures, depending on a desired dough consistency and texture. Said materials may combine in the kneading assembly 128 to form a homogeneous batch of dough suitable for processes including, but not limited to, baking, cooking, or further processing.
[0020] In some embodiments, the food processing device 100 may include a roller assembly 134 to perform the rolling operation of the kneaded ingredient. The roller assembly 134 may define a first coupling end 134a and a second coupling end 134b opposite to the first coupling end 134a. In some embodiments, the roller assembly 134 includes a base plate 136 defining a first surface 136a to receive the kneaded ingredient. The base plate 136 may define a second surface 136b opposite to the first surface 136a. The second surface 136b may define a coupling portion 138. The coupling portion 138 may correspond to a hole 138a having a plurality of internal teeth 138b to be engaged with the first coupling end 134a of the roller assembly 134 (as shown in FIG. 6A). In some embodiments, the roller assembly 134 may include one or more roller pins 140 movable with respect to the base plate 136 to flatten the kneaded ingredient to a flattened kneaded material. In some embodiments, the one or more roller pins 140 may include a first roller pin 140a and a second roller pin 140b. In some embodiments, the one or more roller pins 140 may be coupled with a handle assembly 144. The handle assembly 144, defining a handle H, may include one or more elongated portions pivotally coupled with the first section 104 of the food processing device 100. In some embodiments, at least two elongated portion, for example, 144a, 144b may be pivotably coupled to both sides of the first section 104 and configured to between a stowed position and a deployed position with respect to the base plate 136 (as shown in FIG. 2 and FIG. 3, discussed later in details). The one or more roller pins 140 may be provided between the elongated portions 144a, 144b. In operation, the handle assembly 144 (along with the one or more roller pins 140) may be pivotally movable with respect to the base plate 136, from its stowed position to the deployed position, to flatten the kneaded ingredient to the flattened kneaded material. In some embodiments, when in the stowed position, the elongated portions 144a, 144b may be placed on a stopper 141 to restrict movement of the elongated portions 144a, 144b to after predetermined position.
[0021] In some embodiments, the roller assembly 134 may include a torque transmission device 146 defining a first transmission end 158 and a second transmission end 160 opposite to the first transmission end 158. The torque transmission device 146 may be configured to be engageable with the coupling portion 138 of the base plate 136. In this state, the torque transmission device 146 may be configured to be coupled with the driveshaft 122 of the food processing device 100 to transfer torque from the driveshaft 122 to the base plate 136. Upon transferring torque from the driveshaft 122 to the base plate 136, the torque transmission device 146 may be configured to facilitate rotation of the base plate 136 at a second rotational speed different from the first rotational speed of the driveshaft 122. For example, the torque transmission device 146 may be configured to receive the second rotational motion of the driveshaft 122 and provide the second rotational speed. In some embodiments, the second rotational speed of the base plate 136 may be different from the first rotational speed of the driveshaft 122. For example, the second rotational speed of the base plate 136 may lower than the first rotational speed of the driveshaft 122. In some embodiments, the first rotational speed may be greater than 200 RPM value and the second rotational speed may be lower than 200 RPM value.
[0022] In some embodiments, the torque transmission device 146 may be configured to be engageable with the blade 132 of the kneading assembly 128. In this state, the torque transmission device 146 may be configured to be coupled with the driveshaft 122 of the food processing device 100 to transfer torque from the driveshaft 122 to the blade 132. Upon transferring torque from the driveshaft 122 to the blade 132, the torque transmission device 146 may be configured to facilitate rotation of the blade 132 at the second rotational speed different from the first rotational speed of the driveshaft 122.
[0023] Referring to FIG. 2 and FIG. 3, the food processing device 100 is shown to perform the kneading operation and the rolling operation upon activating a single switch, for example, a switch S. In some embodiments, the driveshaft 122 of the food processing device 100 may be coupled with the blade 132 of the kneading assembly 128 (carrying the edible material and the liquid material). The switch S may be turned on to activate the motor 108 and configure the blade 132 of the kneading assembly 128 to knead the edible material with the liquid material to knead the dough for making the kneaded ingredient. In some embodiments, during the kneading operation, the driveshaft 122 may facilitate rotation of the blade 132 of the kneading assembly 128 at the first rotational speed. In some embodiments, the kneading operation may require less rotational speed and the torque transmission device 146 may be coupled with the blade 132 of the kneading assembly 128 facilitating rotation of the blade 132 at the second rotational speed. In some embodiments, the kneading assembly 128 may be coupled with the second transmission end 160 (or a carrier 160a of the second transmission end 160, discussed later). Once the kneaded ingredient is prepared, a bit of dough may be removed from the kneaded ingredient. Simultaneously, the kneading assembly 128 is removed and the driveshaft 122 of the food processing device 100 may be coupled with the second coupling end 134b of the roller assembly 134 to roll the bit of dough of the kneaded ingredient. For example, the bit of dough or a dough portion may be placed on the first surface 136a of the base plate 136 and the one or more roller pins 140 (or the handle assembly 144) may be placed in the deployed position. In this configuration, the torque transmission device 146 may facilitate rotation of the base plate 136 at the second rotational speed different from the first rotational speed. For example, in the deployed position, the one or more roller pins 140 may rotate transversely with respect to a rotational direction of the base plate 136. In some embodiments, the first roller pin 140a of the one or more roller pins 140 may be configured to rotate in a first rotational direction when in rollable contact with the kneaded ingredient. Further, the second roller pin 140b of the one or more roller pins 140 may be configured to rotate in a second rotational direction when in rollable contact with the kneaded ingredient. In some embodiments, the first rotational direction and the second rotational direction may transverse to the rotational direction of the base plate. In some embodiments, the second rotational direction (e.g., an anticlockwise direction) is opposite to the first rotational direction (e.g., in a clockwise direction).
[0024] Referring to FIGs. 4A and 4B, the food processing device 100 may include a height adjusting mechanism 148 for adjusting a height d of the one or more roller pins 140. In some embodiments, the height adjusting mechanism 148 may be configured to adjust the height d of the one or more roller pins 140 with respect to the first surface 136a of the base plate 136. For example, the height adjusting mechanism 148 may include a height adjusting lever 150 provided in a slot 152 of the food processing device 100. The height adjusting lever 150 may be configured to being moved to at least one of a plurality of height adjusting positions to adjust the height d of the one or more roller pins 140. In other words, when in the deployed position, the elongated portions 144a, 144b, may rest on the height adjusting lever 150 to keep the one or more roller pins 140 at a particular distance from the base plate 136. In this state, the height of the one or more roller pins 140 with respect to the base plate 136 may be adjusted by keeping the height adjusting lever 150 at a particular location within the slot 152. Accordingly, when the bit of dough or the dough portion may be rotated along with the rotation of the base plate 136 and being rolled via the one or more roller pins 140, the height adjusting mechanism 148 facilitates in achieving a desired thickness of the flat edibles by adjusting the height, for example between d and d`, of the one or more roller pins 140 with respect to the base plate 136. In some embodiments, the height adjusting mechanism may facilitate in producing the flat edibles of thickness ranging between 2 to 10 millimeters (mm). It should be noted that the term ‘height’, used herein, may refer to a distance, for example, d or d` between the one or more roller pins 140 and the base plate 136.
[0025] Referring to FIG. 5 and FIGs. 6A and 6B, the roller assembly 134 is shown and described. The roller assembly 134 including the one or more pins, for example, 140a, 140b (with the handle assembly 144), the base plate 136, and the torque transmission device 146 being a single unit may be used with other different mixing units, such as wet grinders, blenders, etc. In this configuration, the one or more roller pins 140 may be pivotally coupled with the torque transmission device 146. In an example, the handle assembly 144 may be pivotally coupled with the torque transmission device 146. The handle assembly 144 may define a Y-shaped portion 144` having two ends, for example, 144c and 144d. A handle H` (similar to the handle H of FIG. 2 or FIG. 3) may be placed between the two ends 144c and 144d and the one or more roller pins may be placed at a sufficient distance from the handle H` between the two ends 144c and 144d, as shown in FIG. 5. In some embodiments, the Y-shaped portion 144` may include an engaging portion 144e pivotally engageable with the torque transmission device 146 via a lock pin P. In some embodiments, the lock pin P may be adjustable longitudinally with respect to the base plate 136 to adjust the height d of the one or more roller pins 140 with respect to the base plate 136.
[0026] Referring to FIG. 7, an exploded view of the roller assembly 134 is shown and described. In some embodiments, the roller assembly 134 may be selectively couplable with the kneading assembly 128 or the base plate 136. Accordingly, when coupling with blade 132 of the kneading assembly 128, the torque transmission device 146 may be configured to transfer torque from the driveshaft 122 to the kneading assembly 128 to facilitate rotation of the blade 132 at the second rotational speed similar to when the torque transmission device 146 being coupled with the base plate 136. In some embodiments, the torque transmission device 146 may include a housing 154 and a lid 156 to cover the housing 154. In some embodiments, the housing 154 may define a bowl section 154b having a bowl surface 154c and a plurality of inner teeth 154a annularly provided on the bowl surface 154c, as shown. In some embodiments, the first transmission end 158 of the torque transmission device 146 may be coupled with the driveshaft 122 of the food processing device 100. The second transmission end 160 of the torque transmission device 146 may be coupled with a carrier 160a defined at the second transmission end 160 to provide the second rotational speed. In some embodiments, the carrier 160a may be a part of the second transmission end 160. In some embodiments, the torque transmission device 146 may include a planetary gear assembly 162 having a at least three planet gears, for example, 162a, 162b, 162c, disposed between the carrier 160a and a bottom support via a second fastening means F2. For example, the planet gears 162a, 162b, 162c may be rotatably engageable with each other and rotatably engageable with the inner teeth 154a in same plane. The rotation of the planet gears 162a, 162b, 162c, may be configured to rotate the carrier 160a at the second rotational speed. To achieve this, the planetary gear assembly 162 may include a sun shaft 164 having a sun gear 164a rotatably engageable with all three planet gears 162a, 162b, 162c. In operation, the sun shaft may be configured to drive the planet gears 162a, 162b, 162c, which are rotatably engaged with an inner teeth 154a and the carrier 160a. In an example, when the sun shaft 164 (coupled with the driveshaft 122) may be rotated at the second rotational motion at the second RPM value, the sun shaft 164 is configured to transfer the second rotational motion to the planet gears 162a, 162b, 162c. the second rotational motion caused the planet gears 162a, 162b, 162c to revolve around their own axes while simultaneously orbiting within the housing 154. As the planet gears 162a, 162b, 162c rotate and mesh with the inner teeth 154a of the housing 154, the planet gears 162a, 162b, 162c may configure to drive the carrier 160a of the second transmission end 160. Driving the carrier 160a may produces an output rotation at the second rotational speed. Due to such gear arrangement, the rotational speed (i.e., the second rotational speed) produced by the carrier 160a may be lower than the second rotational motion of the driveshaft 122. In such configuration, the planetary gear assembly 162 of the torque transmission device 146 may facilitate a significant speed reduction while maintaining torque transmission, making the food processing device 100 effective for the rolling operations and in some cases for the kneading operation as well. In some embodiments, the first transmission end 158 may include a first coupling portion 166 rotatably engageable with the driveshaft 122 to transmit the second rotational motion to the sun shaft 164. In some embodiments, a second bearing device 168 may be provided between the sun shaft 164 and the housing 154 of the torque transmission device 146. In some embodiments, the torque transmission device 146 may include a second coupling portion 170 rotatably coupled with the carrier 160a to transmit the second rotational speed to at least one of the kneading assembly 128 or the roller assembly 134.
[0027] Referring to FIG. 8, a food processing device 200, similar to the food processing device 100, is disclosed and described. the food processing device 200 may correspond to a grinder, a wet grinder, or a blender, as shown. In some embodiments, the food processing device 200 may be operated at different speeds and that may be changed adjusted using a knob 202. For example, the food processing device 200 may include a housing 204 having a drive assembly or a motor (not shown) disposed within the housing 204. In some embodiments, the food processing device 200 may be coupled with the torque transmission device 146 to produce the second rotational speed. At least one of the kneading assembly 128 or the roller assembly 134 may be engaged with the torque transmission device 146 coupled with the food processing device 200 to perform corresponding kneading operations or rolling operations.

[0028] The present disclosure provides the food processing device 100 having the kneading assembly 128 for kneading operations and the roller assembly 134 for the rolling operations. The food processing device 100 may include the motor 108 for powering kneading and rolling operations of the food processing device 100. The food processing device 100 may include the driveshaft 122 operably coupled with the output shaft 108a of the motor 108. The kneading assembly 128 of the food processing device 100 may include the blade 132 couplable with the driveshaft 122 to mix the edible material with the liquid material and knead the dough for making the kneaded ingredient. The roller assembly 134 of the food processing device 100 may include the base plate 136 defining the first surface 136a and the second surface 136b opposite to the first surface 136a. The first surface 136a may receive the kneaded ingredient, and the second surface may define the coupling portion 138. The roller assembly 134 may include one or more roller pins 140 movable with respect to the base plate 136 to flatten the kneaded ingredient to the flattened kneaded material. The roller assembly 134 may include the torque transmission device 146 may be engageable with the coupling portion 138 of the base plate 136. The torque transmission device 146 may be configured to be coupled with the driveshaft 122 to transfer torque from the driveshaft 122 to the base plate 136. The torque transmission device 146 may be configured to facilitate rotation of the base plate 136 at the second rotational speed different from the first rotational speed of the driveshaft.
[0029] The torque transmission device 146 may enable the base plate 136 to rotate at the second rotational speed different from the first rotational speed of the driveshaft 122, effectively reducing an effective RPM at which the kneaded ingredient is flattened. Typically, conventional food processing devices may lead to inconsistencies in dough texture of the kneaded ingredient and thickness of the flattened kneaded material. The present food processing device 100 having the torque transmission device 146, may configure the rotational speed of the base plate 136 reduced to an optimal range, ensuring that the one or more roller pins 140 apply uniform pressure while flattening the kneaded ingredient. In an example, said optimal range may range between 150 to 300 RPM for the base plate 136 may cause the one or more roller pins 140 to flatten the kneaded ingredient to a flattened and round kneaded material within 40 seconds. In some embodiments, the food processing device 100 may provide a controlled reduction in rotational speed prevents excessive stress on the kneaded ingredient, mitigating overheating effects, and preserving integrity of gluten structures, which is essential for making consistent rotis, chapatis, or other flatbreads.
