Description

Technical Field

[0001] This invention relates to the field of automatic cooking equipment technology, specifically to a powdered seasoning feeding structure for an automatic stir-fry machine, which is particularly suitable for automatic quantitative selection and feeding of powdered seasonings. Background Technology

[0002] With the accelerating pace of life and rising labor costs, automatic cooking machines, as intelligent kitchen equipment, are being used more and more widely. In automatic cooking machines, the automatic addition of seasonings is one of the key steps affecting the consistency of dish flavor and cooking efficiency. Powdered seasonings (such as salt, sugar, chicken essence, MSG, pepper, Sichuan peppercorn powder, chili powder, etc.) present many technical challenges in automatic quantitative feeding due to their poor flowability, tendency to clump, and tendency to generate dust.

[0003] To achieve automated quantitative feeding of powdered seasonings, several solutions have been proposed in the existing technology. For example, one solution uses a screw conveyor, where each hopper stores a different type of powdered seasoning. The seasoning moves along the spiral grooves on the screw rod towards the feeding outlet and then falls out from the outlet. Each type of seasoning is discharged through its own screw rod. Another solution uses multiple automatic feeding mechanisms, each including a container, a first drive motor, a first screw feeding rod, a second drive motor, a second screw feeding rod, and a controller. In addition, some solutions install a baffle at the discharge port of the screw conveyor, which is moved by an electric actuator to block the discharge port and prevent material leakage when changing containers.

[0004] However, all of the above-mentioned existing technical solutions have varying degrees of drawbacks:

[0005] First, the baffle mechanism is complex when multiple seasonings work together. When multiple seasonings need to be used simultaneously, the existing solution usually requires a baffle and an independent drive mechanism to be set at the discharge port of each screw conveyor, which leads to complex structure, increased cost, inconvenient control, and difficulty in synchronizing the opening and closing timing of each output port.

[0006] Secondly, the conveying method after the powdered seasoning is output is inefficient and energy-intensive. In existing solutions, after the powdered seasoning is output by the screw conveyor, it usually falls directly into the wok by gravity or is conveyed by side blowing. The gravity falling method is limited by the relative position between the seasoning outlet and the wok, making the arrangement inflexible; the side blowing method requires a large air pressure (usually more than 5 atmospheres), and because the airflow forms an arc-shaped airflow in the pipe, it can only carry away the powder at the top, making it difficult to blow away all the powder accumulated at the bottom, resulting in incomplete discharge and a large amount of residue.

[0007] Third, the material discharge from the seasoning tanks is obstructed. In existing solutions, seasoning tanks are mostly set vertically or horizontally. When powdered seasonings fall under their own weight, they tend to accumulate and arch at the bottom of the tank, leading to obstructed or even interrupted discharge. Although some solutions use a screw conveyor for forced feeding, the connection structure between the seasoning tank and the screw conveyor mechanism is not designed reasonably. Before entering the screw conveyor pipe, the powder may not be able to slide down smoothly due to an excessively large angle of accumulation.

[0008] In summary, existing powdered seasoning feeding technologies, when applied to automatic cooking machines, suffer from several technical drawbacks, including complex baffle mechanisms when multiple seasonings work together, low powder conveying efficiency and high energy consumption, and poor material discharge from the seasoning tank. Therefore, there is an urgent need in this field for a powdered seasoning feeding structure that is simple in structure, enables selective feeding of multiple seasonings, and achieves efficient and low-energy powder conveying. Summary of the Invention

[0009] The purpose of this invention is to provide a powdered seasoning feeding structure, which aims to solve the technical problems of complex baffle mechanism, low powder conveying efficiency and high energy consumption, and poor material discharge from seasoning tanks when multiple seasonings work together in the powdered seasoning feeding process of existing automatic cooking machines.

[0010] To achieve the above objectives, the present invention provides the following technical solution:

[0011] A powdered seasoning feeding structure includes a seasoning rack, a seasoning conveying mechanism, a baffle mechanism, a storage channel, and an air blowing mechanism. The seasoning rack is used to mount at least one powdered seasoning container. The seasoning conveying mechanisms are correspondingly located at the outlets of the powdered seasoning containers. Each seasoning conveying mechanism starts and stops independently to control whether the powdered seasoning in the corresponding container is output, achieving selective feeding of one or more powdered seasonings. The baffle mechanism is located downstream of the output end of each seasoning conveying mechanism, used to simultaneously block or open all the output ports of the seasoning conveying mechanisms. The storage channel is located downstream of the baffle mechanism, used to receive and temporarily store the powdered seasoning output by the seasoning conveying mechanisms. The air blowing mechanism is located at the bottom of the storage channel, used to blow air upwards from the bottom of the storage channel, blowing the powdered seasoning in the storage channel out from the outlet above the storage channel.

[0012] Preferably, the seasoning conveying mechanism includes a screw conveying assembly, which includes a conveying pipe, a screw rod disposed in the conveying pipe, and a drive motor for driving the screw rod to rotate. The outlet of the powdered seasoning tank is connected to the conveying pipe, and the screw rod pushes the powdered seasoning to the output end of the conveying pipe when it rotates.

[0013] Preferably, the seasoning rack has multiple mounting positions arranged vertically, and each of the powdered seasoning containers is respectively disposed at the corresponding mounting position; the powdered seasoning container is inclined relative to the seasoning rack, and the inclination angle is such that the powdered seasoning in the powdered seasoning container can slide down to the discharge port by gravity.

[0014] Preferably, the bottom of the powdered seasoning container is provided with a powdered base, the powdered base has a channel extending downward at an incline, the channel is connected to the conveying pipe of the screw conveyor assembly, and the inclination angle of the powdered base is the maximum limit slope angle at which the powdered seasoning can slide freely under gravity.

[0015] Preferably, the baffle mechanism includes a baffle body and a drive assembly. The baffle body extends along the arrangement direction of the output ends of each of the seasoning conveying mechanisms, and the baffle body has openings corresponding one-to-one with the output ports of each of the seasoning conveying mechanisms. The drive assembly is connected to the baffle body and is used to drive the baffle body to reciprocate, so that each opening is simultaneously aligned with or simultaneously offset from the corresponding output port. When the baffle body moves to a first position, each opening is flush with the corresponding output port, and all the output ports are opened simultaneously; when the baffle body moves to a second position, each opening is offset from the corresponding output port, and all the output ports are simultaneously blocked by the baffle body.

[0016] Preferably, the driving component is a cylinder, which is disposed on one side of the baffle body and drives the baffle body to reciprocate in the vertical direction.

[0017] Preferably, the storage channel includes a storage tank and a discharge port disposed above the storage tank. The air blowing mechanism is disposed at the bottom of the storage tank. When the air blowing mechanism blows air into the storage tank, the powdered seasoning in the storage tank moves upward under the action of the airflow and is discharged from the discharge port.

[0018] Preferably, the blowing mechanism includes an air inlet located at the bottom of the storage tank and an air pipe connected to the air inlet. External compressed gas is sprayed upward from the bottom of the storage tank through the air inlet, blowing away the powdered seasoning in the storage tank and carrying it to the discharge port.

[0019] Preferably, the top of the powdered seasoning container is provided with a visual observation window.

[0020] Preferably, there are multiple powdered seasoning tanks and seasoning conveying mechanisms, and each seasoning conveying mechanism works independently to achieve independent quantitative output and selective feeding of various powdered seasonings.

[0021] The present invention has the following beneficial effects:

[0022] First, a single baffle mechanism enables the overall shielding or opening of all output ports, resulting in a simple structure and convenient control. The baffle mechanism is a long, strip-shaped baffle body extending along the output end arrangement direction of each seasoning conveyor mechanism. The baffle body has openings corresponding to each output port. By driving the baffle body to reciprocate through a single drive component, all openings can be simultaneously aligned with or offset from their corresponding output ports, achieving synchronous opening or shielding of all output ports. Compared to existing technologies where each output port has a separate baffle, this invention significantly simplifies the structure, reduces costs considerably, and offers more convenient control.

[0023] Secondly, each seasoning conveyor can be started and stopped independently, enabling selective dispensing. Each powdered seasoning container corresponds to an independent seasoning conveyor, and each conveyor can be controlled to start and stop independently. During cooking, the seasoning conveyor corresponding to the seasoning to be added can be selectively activated according to the recipe, enabling selective dispensing and quantitative output of single or multiple powdered seasonings, flexibly meeting the seasoning needs of different dishes.

[0024] Third, the bottom-blowing method achieves efficient and low-consumption powder conveying. An air-blowing mechanism is installed at the bottom of the storage channel, blowing air upwards from the bottom to expel the powdered seasoning from the upper outlet. The bottom-blowing method can completely disperse and carry away the powder accumulated at the bottom of the storage tank, eliminating the problem of side-blowing methods only carrying away powder from the top. Experimental data shows that side-blowing methods require approximately 0.5 MPa (5 standard atmospheres) to disperse all accumulated powder, while the bottom-blowing method only requires 0.1–0.2 MPa of compressed gas to easily complete the blowing, significantly reducing energy consumption (approximately 1 / 5 to 1 / 10 of side-blowing methods), resulting in more thorough and reliable discharge.

[0025] Fourth, the seasoning cans are tilted to ensure smooth feeding. The powdered seasoning cans are tilted relative to the seasoning rack, with the tilt angle allowing the powdered seasonings to slide freely under gravity. The powder base at the bottom of the seasoning can has a downward-sloping channel, with the tilt angle being the maximum limit slope angle that allows the powdered seasonings to slide freely under gravity. This design allows the powdered seasonings to slide smoothly into the screw conveyor mechanism under gravity, avoiding problems such as powder accumulation, bridging, and obstructed feeding caused by vertical or horizontal placement of the seasoning cans.

[0026] In summary, this invention forms a complete and systematic solution, from the inclined arrangement of the seasoning tank, the independent control of the screw conveyor mechanism, the overall shielding of the baffle mechanism to the bottom air blowing of the storage channel. The various structures work together to ensure the smoothness, selectivity and efficiency of the powdered seasoning feeding process. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example 1: Overall Structure of the Device

[0043] like Figure 1 As shown, the present invention provides a powdered seasoning feeding structure, including a seasoning rack 1, a powdered seasoning tank 2, a seasoning conveying mechanism 3, a baffle mechanism 4, a storage channel 5, and an air blowing mechanism.

[0044] The spice rack 1 is used to install multiple powdered spice containers 2. The spice rack 1 has multiple mounting positions 11 arranged vertically, and each powdered spice container 2 is respectively installed in the corresponding mounting position 11. The number of powdered spice containers 2 can be set according to actual needs. For example, six, eight or more powdered spice containers 2 can be set to hold different kinds of powdered seasonings such as salt, sugar, chicken essence, monosodium glutamate, pepper powder, Sichuan pepper powder, and chili powder.

[0045] Each powdered seasoning container 2 corresponds to a seasoning conveying mechanism 3. The seasoning conveying mechanism 3 is located at the outlet of the powdered seasoning container 2 and is used to quantitatively output the powdered seasoning from the powdered seasoning container 2.

[0046] The baffle mechanism 4 is located downstream of the output end of each seasoning conveying mechanism 3, and is used to simultaneously cover or open the output ports of all seasoning conveying mechanisms 3.

[0047] The storage channel 5 is located downstream of the baffle mechanism 4 and is used to receive and temporarily store the powdered seasonings output by the seasoning conveying mechanism 3.

[0048] The air blowing mechanism is located at the bottom of the storage channel 5 and is used to blow air upward from the bottom of the storage channel 5 to blow the powdered seasoning in the storage channel 5 out from the discharge port 52 above the storage channel 5 and into the wok. Example 2: Arrangement of seasoning rack and powder seasoning container

[0049] like Figures 1-6 As shown, the condiment rack 1 has multiple mounting positions 11 arranged vertically. Each powdered condiment container 2 is respectively installed at its corresponding mounting position 11.

[0050] The powdered seasoning container 2 is tilted relative to the seasoning rack 1. The tilt angle is such that the powdered seasoning inside the container 2 can slide down to the discharge port under gravity. Specifically, if the tilt angle of the powdered seasoning container 2 is too small (too flat), the powdered seasoning cannot slide down smoothly under gravity and will accumulate at the bottom of the container; if the tilt angle is too large (close to 90°), the powdered seasoning containers 2 cannot be stacked compactly, occupying a large amount of space. Therefore, the tilt angle of the powdered seasoning container 2 needs to be minimized as much as possible while ensuring that the powder can slide down freely, in order to achieve a compact arrangement.

[0051] The bottom of the powdered seasoning container 2 is provided with a powder base 21. The powder base 21 has a channel extending downward at an incline, which is connected to the conveying pipe 31 of the seasoning conveying mechanism 3. The inclination angle of the powder base 21 is the maximum limit slope angle at which the powdered seasoning can slide freely under gravity—that is, at this angle, the powdered seasoning can just slide continuously down the channel under the action of gravity without accumulating.

[0052] In practical design, the tilt angle of the powder base 21 needs to be determined based on the angle of repose of the powdered seasoning. Different powdered seasonings have different angles of repose; for example, the angle of repose of salt is approximately 30°–35°, and that of flour is approximately 40°–45°. The tilt angle of the powder base 21 should be greater than the angle of repose of the powdered seasoning it contains to ensure that the powder can continuously slide down. Example 3: Structure of the seasoning conveying mechanism

[0053] like Figure 2 As shown, the seasoning conveying mechanism 3 includes a screw conveying assembly. The screw conveying assembly includes a conveying pipe 31, a screw rod 32 disposed within the conveying pipe 31, and a drive motor 33 for driving the screw rod 32 to rotate.

[0054] The outlet of the powdered seasoning tank 2 (i.e., the end of the channel of the powdered base 21) is connected to the conveying pipe 31. When the drive motor 33 drives the screw rod 32 to rotate, the screw blades on the screw rod 32 push the powdered seasoning that falls into the conveying pipe 31 along the conveying pipe 31 to the output end of the conveying pipe 31.

[0055] Each seasoning conveying mechanism 3 has its own independently controlled drive motor 33, which can be started and stopped independently. When a certain powdered seasoning needs to be added, the drive motor 33 corresponding to that seasoning is started, and the screw rod 32 rotates to push the powdered seasoning to the output end; when no addition is needed, the drive motor 33 stops, and the seasoning is not output. By independently starting and stopping each seasoning conveying mechanism 3, selective feeding and quantitative output of single or multiple powdered seasonings are achieved.

[0056] The drive motor 33 is preferably a stepper motor or a servo motor. By controlling the number of rotations of the motor, the feeding amount of the screw rod 32 can be precisely controlled, thereby realizing the quantitative output of powdered seasoning. Example 4: Structure of the baffle mechanism

[0057] like Figure 3 As shown, the baffle mechanism 4 includes a baffle body 41 and a drive assembly 42.

[0058] The baffle body 41 extends along the arrangement direction of the output ends of each seasoning conveying mechanism 3 and is a long strip-shaped plate. The baffle body 41 is provided with openings 411 that correspond one-to-one with the output ports of each seasoning conveying mechanism 3.

[0059] The drive assembly 42 is connected to the baffle body 41 and is used to drive the baffle body 41 to reciprocate, so that each opening 411 is simultaneously aligned with or simultaneously offset from the corresponding output port. The drive assembly 42 is preferably a cylinder, which is located below the baffle body 41 and drives the baffle body 41 to reciprocate in the vertical direction.

[0060] The baffle body 41 moves to the first position (e.g.) Figure 3 When (as shown), each opening 411 is flush with the corresponding output port, and all output ports are opened at the same time. The powdered seasonings output by each seasoning conveying mechanism 3 can fall into the downstream storage channel 5 through the output port and opening 411.

[0061] The baffle body 41 moves to the second position (e.g.) Figure 3 As shown, each opening 411 is offset from its corresponding output port, and all output ports are simultaneously blocked by the baffle body 41. Each output port is closed, so even if the seasoning conveying mechanism 3 is in working condition, the powdered seasoning cannot fall into the storage channel 5 through the output port.

[0062] The function of the baffle mechanism 4 is as follows: when no seasoning is needed, the baffle body 41 covers all outlets to prevent accidental material discharge due to malfunction of the seasoning conveying mechanism 3 or residual powder falling; when seasoning needs to be added, the baffle body 41 opens all outlets, and each seasoning conveying mechanism 3 operates independently to achieve selective material discharge. The baffle mechanism 4 only provides overall covering or opening and does not participate in the selective control of each outlet; selective control is achieved by the independent start and stop of each seasoning conveying mechanism 3. Example 5: Structure of the material storage channel and the air blowing mechanism

[0063] like Figure 4 As shown, the storage channel 5 includes a storage tank 51 and a discharge port 52 disposed above the storage tank 51. The storage tank 51 is used to receive and temporarily store the powdered seasoning output by the seasoning conveying mechanism 3.

[0064] An air blowing mechanism is located at the bottom of the storage tank 51. The air blowing mechanism includes an air inlet 61 located at the bottom of the storage tank 51 and an air pipe communicating with the air inlet 61. External compressed gas (such as compressed air) is ejected upward from the bottom of the storage tank 51 through the air pipe and the air inlet 61.

[0065] When the air blowing mechanism blows air into the storage tank 51, the powdered seasoning in the storage tank 51 is blown away and moves upward under the action of the airflow, and is discharged from the discharge port 52 above the storage tank 51 and enters the wok.

[0066] The blowing method of this invention is blowing air from the bottom upwards. Compared with the side blowing method, bottom blowing has the following significant advantages:

[0067] When the airflow is directed from the side, it forms an arc-shaped flow within the storage tank, which can only carry away the powder at the top, while the powder accumulated at the bottom cannot be carried away by the airflow. To disperse all the accumulated powder, extremely high air pressure is required (usually more than 5 atmospheres), resulting in high energy consumption and unsatisfactory performance.

[0068] During bottom blowing, the airflow is ejected upwards from the bottom of the storage tank, directly acting on the powder accumulated at the bottom, dispersing the powder and carrying it upwards. Because the airflow direction is opposite to the direction of gravity of the powder, the powder is fluidized under the action of the airflow, allowing it to be evenly dispersed and carried out. Experimental data shows that bottom blowing only requires 0.1–0.2 MPa of compressed gas to completely disperse the accumulated powder and complete the discharge, significantly reducing energy consumption (only 1 / 50th of that of side blowing), and making the discharge more thorough and reliable.

[0069] The material of the storage tank 51 is preferably nylon, which has good wear resistance and corrosion resistance, and the inner wall is smooth and does not easily adhere to powdery seasonings. Example 6: Visual Observation Window

[0070] The top of the powdered seasoning container 2 is provided with a viewing window 7. The viewing window 7 is preferably tempered glass, which has good transparency and heat resistance.

[0071] Operators can visually observe the remaining amount of powdered seasoning in the powdered seasoning tank 2 through the visual observation window 7, promptly detect any shortage of seasoning and replenish it, thus avoiding disruption to the continuous operation of the cooking machine due to the depletion of seasoning.

[0072] In addition, the visualization window 7 can also be used to observe the state of powdered seasonings in the container (such as whether they are clumped or damp), which facilitates timely maintenance and handling. Example 7: The working process of the device

[0073] The working process of the powdered seasoning feeding structure of the present invention will be described below with reference to the accompanying drawings.

[0074] Step 1: Initial State. The baffle body 41 of the baffle mechanism 4 is in the second position, with each opening 411 offset from its corresponding output port, and all output ports are blocked by the baffle body 41. The drive motors 33 of each seasoning conveying mechanism 3 are all in the stopped state.

[0075] Step 2: The baffle opens. When seasonings need to be added, the drive assembly 42 (cylinder) drives the baffle body 41 to move upward to the first position, and each opening 411 is flush with the corresponding output port, and all output ports open at the same time.

[0076] Step 3: Selective Dispensing. Based on the recipe, the drive motor 33 corresponding to the seasoning to be dispensed is activated. The drive motor 33 drives the screw rod 32 to rotate, pushing the powdered seasoning from the corresponding powdered seasoning container 2 to the output port, where it falls into the storage trough 51 of the storage channel 5 through the output port and opening 411. The drive motor 33 for seasonings that do not need to be dispensed remains stationary. By controlling the start / stop and rotation number of each drive motor 33, selective dispensing and quantitative output of single or multiple powdered seasonings can be achieved.

[0077] Step 4: Baffle closes. After the material is discharged, the drive assembly 42 drives the baffle body 41 to move downward to the second position. Each opening 411 is offset from the corresponding output port, and all output ports are blocked by the baffle body 41 to prevent residual powder from falling.

[0078] Step 5: Bottom-blowing discharge. The air-blowing mechanism blows air upwards from the bottom of the storage tank 51. External compressed gas is ejected upwards from the bottom through the air inlet 61, blowing away the powdered seasoning in the storage tank 51 and carrying it upwards. It is then discharged from the discharge port 52 above the storage tank 51 and enters the wok. Because a bottom-blowing method is used, only 0.1-0.2 MPa of compressed gas is needed to blow away all the accumulated powder and complete the discharge.

[0079] Step Six: Reset. After the air blowing is completed, the air blowing mechanism stops working, and the device returns to standby mode, waiting for the next feeding command. Example 8: Application Scenarios

[0080] The powdered seasoning feeding structure of the present invention can be applied to the automatic quantitative addition of powdered seasonings in automatic cooking machines.

[0081] In the automatic cooking machine, multiple powdered seasoning containers 2 are arranged in rows at an angle on the seasoning rack 1, containing different types of powdered seasonings such as salt, sugar, chicken essence, MSG, pepper powder, Sichuan pepper powder, and chili powder. According to the recipe program, the cooking machine controls the corresponding seasoning conveying mechanism 3's drive motor 33 to start in real time during the cooking process, quantitatively outputting the required powdered seasonings to the storage channel 5, and then delivering the seasonings into the wok via bottom air blowing.

[0082] Industrial applicability

[0083] The powdered seasoning feeding structure of this invention is rationally designed and reliably operates, effectively solving the technical problems of complex baffle mechanisms, low powder conveying efficiency, high energy consumption, and poor material discharge from the seasoning tank when multiple seasonings work together during the powdered seasoning feeding process. The various mechanisms of the device cooperate seamlessly, achieving a high degree of automation and strong adaptability, and can be widely applied to the automatic quantitative addition of powdered seasonings in various automatic cooking machines. Its overall shielding design of the single baffle mechanism simplifies the structure and reduces costs; independent control of each seasoning conveying mechanism enables selective material discharge; the bottom blowing method significantly reduces energy consumption compared to the side blowing method (requiring only 0.1–0.2 MPa compressed gas), and the discharge is more thorough and reliable; the inclined arrangement of the seasoning tank ensures smooth powder discharge. The above structural design has reasonable manufacturing costs, is easy to maintain, and has significant industrial practical value and promising prospects for promotion.
