Description

Technical Field

[0001] This utility model relates to the field of food production technology and is a three-section flipping naan baking machine. Background Technology

[0002] Naan is a representative food of Xinjiang. Making this food is inseparable from the naan oven. Due to environmental protection requirements, coal-fired naan ovens have been basically replaced by electric naan ovens, which are called electric naan ovens or naan ovens.

[0003] This type of electric tandoor oven (used in stores) is cube-shaped, consisting of an inner and outer shell. The space between the outer and inner shells is filled with insulation material. The inner shell is urn-shaped, with a heating plate at the bottom center containing multiple heating tubes. The tandoor oven has a circular opening with a diameter of 40 to 50 centimeters. When baking naan, the dough is placed on the tandoor pillow, enters through the opening, and then the dough is firmly pressed against the side wall of the inner shell for baking.

[0004] During baking, the color of the naan bread needs to be constantly observed. When the surface of the naan bread turns slightly yellow, it should be hooked down, turned 180 degrees, and placed upright on the bottom wall of the inner pot to continue baking. This is because the naan bread attached to the inner pot wall receives different temperatures from top to bottom; the side closer to the heating plate gets a higher heat and a darker color, while the other side is lighter. Therefore, when it is almost done, it should be removed, turned upside down, and baked until the color is basically uniform before it can be sold. This type of tandoor oven has the following drawbacks:

[0005] First, there is a serious waste of energy. Because constant observation is required during the baking process, the opening at the top of the oven is almost always open. This results in a significant loss of heat from the oven, with more than half of the heat being lost, leading to half of the electricity consumed being wasted.

[0006] Secondly, the operation procedure is complex and difficult to control manually. When baking naan, the operator has to constantly observe the color of the naan, remove the naan that is almost cooked, turn it around, and bake it again until the color is even before removing it. This increases the workload of the operator, and at the same time, it is easy to overcook the naan if you are not careful, causing the naan to burn and affecting sales.

[0007] Third, the working conditions are harsh and have a significant impact on the environment. Because a large amount of heat comes out from the top of the oven when baking naan bread, it constantly scorches the workers, making their work very painful, especially in the summer. In addition, due to the large amount of heat released, shops usually place the naan oven outside the shop or open the storefront wide to increase heat dissipation in order to work normally.

[0008] Fourth, it frequently burns operators. Because the tandoor oven opening and the inner liner are one piece, heat is conducted to the opening, where the temperature is generally around 200 degrees Celsius. When operators place the naan dough into the inner liner, they often touch the rounded edge of the opening and get burned, which poses a great threat to their health.

[0009] Fifth, it cannot bake softer naan bread. Due to the shape of the tandoor oven, which is wider at the bottom than at the top, the angle between the inner wall and the bottom is less than 90 degrees. When a softer dough is placed on it, the dough, due to its low viscosity, will flow off due to gravity. Therefore, traditional electric tandoor ovens cannot bake very soft naan bread. However, with the improvement of living standards, soft Western baked goods are very popular. Naan is actually a type of baking, and soft naan breads such as bread naan have become very popular in recent years. However, traditional tandoor ovens cannot bake softer bread naan breads, thus limiting the compatibility of naan products with modern dietary styles. Summary of the Invention

[0010] This invention provides a three-section rotating naan oven that overcomes the shortcomings of the prior art. It can effectively solve the problems of low efficiency, complicated operation procedures, and inability to bake softer naan bread in existing electric naan ovens.

[0011] The technical solution of this utility model is achieved through the following measures: a three-section flipping naan oven, including a box, a rotating shaft, baking plates, heating tubes and a drive mechanism. The box is provided with an oven cavity, and the upper side of the box is provided with an inlet communicating with the upper part of the oven cavity. A top cover is hinged to the upper side of the box corresponding to the inlet position. A rotating shaft with one end located on the outside of the box is rotatably installed in the oven cavity. Three baking plates located in the oven cavity are evenly distributed along the circumference of the rotating shaft. Two heating tubes are arranged at intervals in the lower part of the oven cavity. A drive mechanism capable of driving the rotating shaft to rotate intermittently is provided on the outside of the box.

[0012] The following are further optimizations and / or improvements to the above-mentioned utility model technical solution:

[0013] Support plates that are fixed together with each baking plate can be fixedly installed on the left and right sides of the aforementioned rotating shaft.

[0014] The aforementioned support plate is a triangular support plate, with upright plates on the left and right sides of each baking plate. The support plate and the upright plates are fixed together, and the three baking plates are fixed together to form a hollow regular triangular prism structure baking plate rack.

[0015] Each of the baking plates can be equipped with baffles on both the front and back sides.

[0016] The upper inner side of the furnace cavity is fixedly installed with a front joint patching plate and a rear joint patching plate at intervals. The left inner side and the right inner side of the furnace cavity are respectively fixed with a left joint patching plate and a right joint patching plate that are spaced apart from the support plate.

[0017] The lower part of the furnace cavity can be recessed to form a heating cavity. The cross-section of the heating cavity is trapezoidal with a larger top and a smaller bottom. Heating tubes are fixedly installed on the front and rear inner walls of the heating cavity. A storage groove with an opening facing forward is provided on the lower front side of the box corresponding to the position below the heating cavity. A through hole communicating with the lower part of the furnace cavity is provided on the upper inner wall of the storage groove. A storage box is slidably installed in the storage groove.

[0018] Both the aforementioned box body and top cover are equipped with insulation layers.

[0019] The aforementioned drive mechanism may include a geared motor, an inductive switch, a controller, and a switch arm. A switch arm is fixedly installed on the outer right side of the rotating shaft corresponding to the right side of the housing. The switch arm has arm heads corresponding to the three baking plates respectively. An inductive switch is fixedly installed on the lower right side of the housing corresponding to the position below the rotating shaft. A geared motor is fixedly installed on the lower right side of the housing corresponding to the position below the inductive switch. The right end of the output shaft of the geared motor is connected to the right end of the rotating shaft. Both the geared motor and the inductive switch are connected to the controller.

[0020] This invention features a reasonable and compact structure. Three baking plates are evenly distributed around the circumference of the rotating shaft within the oven cavity. This design incorporates a triangular prism-shaped combination baking plate, composed of three identical steel plates. Each baking plate can hold dough for baking. The drive mechanism intermittently rotates the rotating shaft, allowing the dough on the baking plate to rotate sequentially within the oven cavity. The dough is baked twice by the heating elements. After a set time, the baking plate rotates to the top and reaches a horizontal position, allowing the baked naan to be removed. This design ensures even heating of the dough, resulting in a consistent color and preventing uneven coloring or burning caused by untimely or unskilled operation.

[0021] This utility model has the following advantages: 1. The outer side of the box and the upper side of the top cover are both fixed with heat insulation layer and the normally closed top cover has the characteristics of energy saving; 2. A joint filling plate is set between the side wall of the box and the combined baking plate to fill the installation gap and prevent the heat loss of the lower oven cavity; 3. The combined baking plate is controlled by the switch arm, the induction switch and the controller to rotate in stages and timed to achieve a three-stage baking mode. Attached Figure Description

Detailed Implementation

[0031] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0032] In this utility model, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as the positional relationships of front, back, top, bottom, left, and right, which are based on the instructions attached. Figure 1 The orientation of the layout is determined by the direction of the map.

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0034] Example 1: As shown in the attached document Figures 1 to 6 As shown, the three-section flipping naan oven includes a housing 1, a rotating shaft 2, baking plates 3, heating tubes 4, and a drive mechanism. The housing 1 has an oven cavity 5. The upper side of the housing 1 has an inlet 6 that communicates with the upper part of the oven cavity 5. A cover 7 is hinged to the upper side of the housing 1 corresponding to the position of the inlet 6. A rotating shaft 2 with one end located outside the housing 1 is rotatably installed inside the oven cavity 5. Three baking plates 3 located inside the oven cavity 5 are evenly distributed along the circumference outside the rotating shaft 2. Two heating tubes 4 are spaced apart at the front and back of the lower part of the oven cavity 5. A drive mechanism capable of driving the rotating shaft 2 to rotate intermittently is provided on the outside of the housing 1.

[0035] According to the requirements, the upper cover 7 is matched with the inlet 6. The upper cover 7 can seal the inlet 6. When heating the dough, the upper cover 7 is in the closed state to prevent the heat in the oven cavity 5 from being lost to the outside, thus achieving the effect of saving energy. The rotating shaft 2 is a hollow shaft. During use, three baking plates 3 are evenly distributed around the outer circumference of the rotating shaft 2 within the oven cavity 5. The baking plates 3 are used to hold the dough. A triangular prism-shaped combination baking plate can be set inside the naan baker. The triangular prism combination baking plate is composed of three identical steel plates. Dough can be pasted onto the surface of each baking plate 3 for baking. The drive mechanism can drive the rotating shaft 2 to rotate intermittently, so that the dough on the baking plate 3 can rotate intermittently in sequence within the oven cavity 5. The dough is baked twice by the heating tube 4 within the oven cavity 5. After the set time is reached, the baking plate 3 will rotate to the top and be in a horizontal position, and the baked naan can be removed. This setting ensures that the dough is heated evenly, and the baked naan has a uniform color. It prevents uneven coloring or burning of naan caused by untimely or unskilled operation. When operating, the top cover 7 is opened, and the working surface is exposed, making it easy to attach the dough to the baking plate 3. This can prevent the operator from being burned by the inlet 6 of the naan baker.

[0036] The above three-section rotating naan bread machine can be further optimized and / or improved according to actual needs:

[0037] Example 2: As an optimization of the above examples, as shown in the appendix. Figures 3 to 6 As shown, support plates 8 are fixedly installed on the left and right sides of the rotating shaft 2, and are fixed together with each baking plate. The support plates 8 are triangular. The three baking plates 3 are fixedly installed together to form a hollow regular triangular prism structure combined baking plate. The left and right sides of the combined baking plate are fixedly installed together with the support plates 8 at the corresponding positions.

[0038] According to requirements, two triangular support plates 8 are fixedly installed on the outer side of the rotating shaft 2 at intervals on the left and right. The left side of the combined baking plate is fixedly installed together with the right side of the left support plate 8, and the right side of the combined baking plate is fixedly installed together with the left side of the right support plate 8. During use, by setting the support plates 8, the baking plate 3 can be reliably fixed together with the rotating shaft 2. When the naan baker is working, the rotation of the combined baking plate is intermittent. After the first stop, the top cover 7 is opened, and one of the three baking plates 3 pauses in a state parallel to the bottom surface of the box 1 (horizontal state). At this time, multiple dough pieces are spread evenly on the surface of the baking plate 3. Then the top cover 7 is closed, and after the heating tube 4 works for a certain period of time, the dough pieces on the surface of the baking plate 3 in the state parallel to the bottom surface of the box 1 harden and set.

[0039] Then, the combined baking plate is rotated 120 degrees by the drive mechanism, and the baking plate 3 with multiple dough pieces is rotated to above the rear heating tube 4. The rear heating tube 4 bakes the lower half of the dough pieces. At this time, another baking plate 3 is rotated to a state parallel to the bottom surface of the box body 1, the top cover 7 is opened, and multiple dough pieces are spread on its surface again. Then the top cover 7 is closed. When the heating tube 4 is working, the dough pieces on the surface of the baking plate 3 that is parallel to the bottom surface of the box body 1 harden and set.

[0040] The combined baking plate is rotated 120 degrees again by the drive mechanism. The baking plate 3, which spreads out multiple dough pieces, rotates to the front heating tube 4. The front heating tube 4 bakes the lower half of the dough pieces, and the rear heating tube 4 bakes the lower half of the dough pieces. At this time, the last baking plate 3 rotates to a state parallel to the bottom surface of the box body 1. The top cover 7 is opened, and multiple dough pieces are spread out on its surface again. Then the top cover 7 is closed. When the heating tube 4 is working, the dough pieces on the surface of the baking plate 3, which is parallel to the bottom surface of the box body 1, harden and set.

[0041] Finally, the combined baking plate is rotated 120 degrees again by the drive mechanism, and the baking plate 3 in the initial position is rotated to a horizontal state. At this time, the dough on its surface has been baked. The top cover 7 can be opened to remove the baked naan bread, and then a new dough can be placed on the surface of the baking plate 3.

[0042] Repeat the above steps to continuously make naan bread. When baking naan bread in the naan baking machine, the baking plate 3 can be divided into two stages at symmetrical angles to bake the bread, so that the dough is heated evenly and the baked naan bread has a consistent color. This prevents uneven coloring or burning of naan bread caused by untimely or unskilled operation.

[0043] Example 3: As an optimization of the above examples, as shown in the appendix. Figures 3 to 6 As shown, each baking plate 3 has upright plates 19 on its left and right sides, and a support plate 8 is fixed to the upright plates 19. Each baking plate 3 also has baffles 9 on its front and rear sides, with adjacent baffles 9 and upright plates 19 fixed together. The upright plates 19 are designed to facilitate connection with the support plate 8 via bolts or other components. The raised ring formed by the baffles 9 and upright plates 19 prevents water from flowing onto the heating pipes at the bottom of the oven during cleaning, thus avoiding damage to the heating pipes. It also catches small amounts of water when making naan bread that requires a small amount of water for baking. During use, this design reduces the gap between the baking plate 3 and the oven cavity 5 wall, allowing the heat from the heating pipes 4 to concentrate in the lower part of the oven cavity 5, thereby shortening the heating time of the dough on the other two baking plates 3 when one baking plate 3 is in a horizontal position.

[0044] Example 4: As an optimization of the above examples, as shown in the appendix. Figure 4 , 5As shown in Figures 6 and 7, a front patching plate 10 and a rear patching plate 11 are fixedly installed at intervals on the upper inner side of the oven cavity 5. The width of the front patching plate 10 and the rear patching plate 11 is equivalent to the distance between the edge of the combined baking plate and the inner wall of the box 1. According to the requirements, a left patching plate 20 and a right patching plate 21 are fixed on the inner left and right sides of the oven cavity 5, respectively. There is a gap between the right side of the left patching plate 20 and the left side of the left support plate 8, and there is a gap between the left side of the right patching plate 21 and the right side of the right support plate 8. This can prevent heat loss and also prevent the left patching plate 20 and the right patching plate 21 from rubbing against the support plate 8. The width of the front patching plate 10 and the rear patching plate 11 is equivalent to the distance between the edge of the combined baking plate and the inner wall of the box 1. That is, the front patching plate 10 and the rear patching plate 11 are located at the horizontal corresponding positions on the triangular prism combined baking plate. The width of the front patching plate 10 and the rear patching plate 11 is equivalent to the distance between the edge of the triangular prism combined baking plate and the inner wall of the box 1.

[0045] In use, when one of the baking plates 3 is in a horizontal state, the distance between the upper side of the baffle 9 on the front side of the horizontal baking plate 3 and the lower side of the front patching plate 10 is minimized. Simultaneously, the distance between the upper side of the baffle 9 on the rear side of the horizontal baking plate 3 and the lower side of the rear patching plate 11 is minimized. This prevents the baffle 9 from rubbing against the front patching plate 10 and the rear patching plate 11 when rotating with the rotating shaft 2. It also divides the oven cavity 5 into upper and lower working chambers. The upper working chamber is the shaping chamber, meaning the oven cavity 5 above the horizontal baking plate 3 is the shaping chamber. The lower part of the oven cavity 5 is the baking chamber, that is, the oven cavity 5 below the horizontal baking plate 3 is the baking chamber. This makes it convenient to place the dough after removing the baked naan from the baking plate 3 in the shaping chamber when heating the dough on the surface of the baking plate 3 inside the baking chamber. At the same time, since the oven cavity 5 is sealed during the baking process, not much heat escapes when the naan machine is working, so it has little impact on the ambient temperature. In addition, since the triangular baking plate 3 blocks most of the radiation from the heating tube 4 and the opening operation time is short, it will not cause high-temperature baking, making the working environment much more friendly.

[0046] Example 5: As an optimization of the above examples, as shown in the appendix. Figure 3 , 4 As shown, the lower part of the furnace cavity 5 is recessed to form a heating cavity 12. The cross-section of the heating cavity 12 is a trapezoid with a larger top and a smaller bottom. Heating tubes 4 are fixedly installed on the front and rear inner walls of the heating cavity 12. A storage groove with an opening facing forward is provided on the lower front side of the box 1 below the heating cavity 12. A through hole communicating with the lower part of the furnace cavity 5 is provided on the upper inner wall of the storage groove. A storage box 18 is slidably installed in the storage groove.

[0047] According to the requirements, the front inner wall and the rear inner wall of the heating cavity 12 are equipped with existing known pipe support frames. The heating pipe 4 is an existing known electric heating pipe. The heating pipe is installed on the two inclined surfaces of the heating cavity 12 through the pipe support frame as required. The angle between the heating pipe 4 and the horizontal plane is 30 to 60 degrees. In this way, when one of the baking plates 3 is in a horizontal state, the dough on the other two baking plates 3 is opposite to the heating pipe 4 on the front inner wall and the rear inner wall of the heating cavity 12. After the heating pipe 4 is powered on, it heats up and bakes the dough on the baking plate 3 from the lower angle. This is more conducive to baking the dough evenly, with higher thermal efficiency and more uniform heating. The storage box 18 can collect the naan crumbs and oil stains during the baking process.

[0048] Example 6: As an optimization of the above examples, as shown in the appendix Figure 3 , 4 As shown in Figures 1 and 5, both the box body 1 and the top cover 7 are provided with an insulation layer 13.

[0049] Depending on the requirements, both the housing 1 and the top cover 7 can be rectangular. Both the housing 1 and the top cover 7 are double-layered structures formed by an inner shell and an outer shell fixed together. The insulation layer 13 is formed by insulation material filled between the outer and inner shells. The insulation material is a known technology, such as rock wool. The insulation layer 13 can prevent internal heat from being conducted to the outside, thus saving energy. When baking naan, the top cover 7 is closed. The baking time is set according to requirements, and the top cover 7 is only opened to remove the naan when the set time is up. Therefore, the oven cavity 5 of the naan baker is closed most of the time during baking, preventing heat loss and saving a significant amount of heat energy and electricity, reducing the production cost of naan. This also reduces the mutual influence between the environment and the baking process and avoids scorching the workers.

[0050] Example 7: As an optimization of the above examples, as shown in the appendix. Figure 1 , 2 As shown in Figures 3, 5 to 8, the drive mechanism includes a geared motor 14, an inductive switch 15, a controller, and a switch arm. A switch arm is fixedly installed on the outer right side of the rotating shaft 2 corresponding to the right side of the housing 1. The switch arm has arm heads 16 corresponding to the three baking plates 3 respectively. An inductive switch 15 is fixedly installed on the lower right side of the housing 1 corresponding to the position below the rotating shaft 2. A geared motor 14 is fixedly installed on the lower right side of the housing 1 corresponding to the position below the inductive switch 15. The right end of the output shaft of the geared motor 14 is connected to the right end of the rotating shaft 2. Both the geared motor 14 and the inductive switch 15 are connected to the controller. Several moving wheels 17 are distributed circumferentially on the lower side of the housing 1.

[0051] According to the requirements, the inductive switch 15 is a known technology, such as a YBLXW limit switch, and the controller is a known technology, such as a PLC programmable controller. When the arm head 16 of the triangular switch arm (which can be formed by fixing three switch plates with the same structure together, with the included angle between the three switch plates being 120 degrees and the side of the three switch plates away from the center being arc-shaped) respectively contacts the contact of the inductive switch 15, the drive motors all stop working. At this time, one baking plate 3 is in a horizontal state. The moving wheel 17 is a known technology, such as a universal caster with a brake, which facilitates the movement of the naan baker. The right end of the output shaft of the geared motor 14 is connected to the right end of the rotating shaft 2 through a known transmission technology, such as a chain drive, a pulley drive, or a gear drive.

[0052] When baking naan with a naan machine, operation is only required while the naan is baked. The operator can complete other auxiliary tasks during the baking process, which saves a lot of operating time and labor costs. It can bake softer naan. When baking naan with a naan machine, the dough is placed on baking plate 3 horizontally with the side of baking plate 3 facing upwards. This allows the dough to adhere stably to baking plate 3. The naan machine is set to a three-stage baking process. The first stage is when the dough is placed on the baking plate, during which there is a resting time of 3 to 10 minutes to allow the dough to rise. At the same time, the high temperature hardens the surface of the dough, and the entire dough is initially shaped. The side of the dough in contact with baking plate 3 quickly adheres to baking plate 3 under the action of high temperature. Then, it rotates to the second stage (rotating shaft 2 rotates 120 degrees) and the third stage (rotating shaft 2 rotates 120 degrees again) for baking. Therefore, even softer dough will not detach from baking plate 3 when flipped downwards.

[0053] The present invention has the following advantages: 1. Both the box body 1 and the top cover 7 are equipped with a heat insulation layer 13 and the normally closed top cover 7 has the characteristic of energy saving; 2. A joint filling plate is provided between the side wall of the box body 1 and the combined baking plate to fill the installation gap and prevent the heat loss of the lower oven cavity 5; 3. The combined baking plate is controlled by the arm head 16 of the switch arm, the induction switch 15 and the controller to rotate in stages and timed to achieve a three-stage baking mode.

[0054] The above technical features constitute various embodiments of this utility model, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.

[0055] The process of using this utility model:

[0056] When using, first connect the power supply, as shown in the attached document. Figure 8As shown, the control box has two circuits, controlling the operation of the heating element 4 and the baking plate 3 respectively. The heating element 4 is controlled by a combination of a temperature sensor and a temperature controller, and the power supply to the heating element 4 is controlled by an AC contactor 1. The baking plate circuit is controlled by a combination of an inductive switch 15 and a controller (preferably a time relay), and the geared motor 14 is controlled by an AC contactor 2 to rotate or stop the baking plate 3. After the temperature controller and the heating element 4 are powered on, the heating element 4 heats the oven cavity 5 to the required operating temperature. The above control process can also use existing technologies and solutions, which can be selected according to the actual situation.

[0057] Open the top cover 7, stick the dough to the surface of the upward-facing baking plate 3, close the top cover 7, and the controller will start the timer baking mode. At this time, the dough that was just put in will be placed in the shaping chamber. When the resting time is over, the reduction motor 14 will drive the rotating shaft 2 to rotate 120 degrees, and the dough will enter the baking chamber.

[0058] The baking chamber consists of two symmetrical parts. The dough first enters the rear part of the baking chamber and is baked there for a period of time. Then, the geared motor 14 drives the rotating shaft 2 to rotate 120 degrees and enter the front part of the baking chamber. At this time, the dough in the front part of the baking chamber is symmetrical with the dough in the rear part of the baking chamber, so that the heating parts of the dough are switched, which makes the surface color of the naan bread more even.

[0059] After a period of static baking, once the set time is reached, the geared motor 14 continues to drive the rotating shaft 2 to rotate 120 degrees, and the naan bread is turned to the horizontal plane. At this point, the three-stage baking process has been completed. The baked naan bread is removed, and a new dough is pasted on and baked again.
