Description

Technical Field

[0001] This utility model relates to the field of food processing, and in particular to an energy-saving multi-blank noodle cooker for cooking noodles, rice noodles, wontons, dumplings, or heating other foods. Background Technology

[0002] Currently, multi-heater noodle cookers use multiple heating units at the bottom of the noodle cooking tank, and there is no isolation between the water bodies above each heating unit, which has the following disadvantages:

[0003] 1. When each heating unit heats, a portion of the heat generated by the unit is diffused laterally by convection. Part of this diffused heat heats the adjacent units, while the other part is lost through steam overflow between the frames of the adjacent units. Only a portion of the heat flows vertically upward to heat the noodles in the frame above the unit. Therefore, the heating efficiency is low.

[0004] 2. When only some of the noodle holes are being cooked, the other heating units also need to heat at high power simultaneously. If the other heating units are not heating, due to the lateral convection and diffusion of heat, less heat is actually received within that noodle hole, resulting in longer cooking time and lower quality. Even when cooking only one serving of noodles, the heating units in the other holes must heat simultaneously, leading to significant energy waste.

[0005] 3. When the noodles are first put into the water, they clump together. As some of the heat dissipates to the surroundings, the number of hot air bubbles rising vertically upwards in the water is greatly reduced, which cannot lift the clump of noodles and separate them. The temperature in the center of the dough rises slowly. Utility Model Content

[0006] To overcome the above-mentioned defects, the purpose of this utility model is to provide a new type of energy-saving multi-eye noodle cooker.

[0007] To achieve the above objectives, the present invention provides an energy-saving multi-hole noodle cooker, which includes at least a noodle cooking tank; multiple heating devices are provided at the bottom of the noodle cooking tank; and a heat-concentrating cover that can be separated from the bottom plate is provided for each heating device in the noodle cooking tank.

[0008] Furthermore, a partition is provided on one side of the noodle cooking tank, which divides the noodle cooking tank into a heating chamber and a preheating chamber;

[0009] A water inlet pipe is provided in the preheating chamber;

[0010] The heating device and heat-concentrating cover are respectively installed in the heating chamber;

[0011] The height of the partition is lower than the height of the noodle cooking tank.

[0012] Furthermore, the heat-concentrating cover is formed by two flat-topped cones or horn shapes joined together, with relatively large openings at the bottom and top.

[0013] Furthermore, the heat-concentrating cover is a flat-topped cone or a trumpet shape.

[0014] Furthermore, the upper part of the heat-concentrating cover is cylindrical or square, and the bottom is flat-topped conical or trumpet-shaped.

[0015] Furthermore, the heat-concentrating cover is cylindrical or square.

[0016] Furthermore, the heat-concentrating cover is a unit divided by partitions.

[0017] Furthermore, a temperature sensor is installed in the noodle cooking tank or on the bottom plate of the noodle cooking tank for each heat-concentrating cover.

[0018] Furthermore, the temperature sensor is a thermocouple, which is directly welded to the base plate.

[0019] Furthermore, the heating device is an electromagnetic heating coil installed under the bottom plate of the noodle cooking tank corresponding to each heat-collecting cover, and the electromagnetic heating coil is connected to a high-frequency power supply through a wire.

[0020] This invention utilizes a heat-concentrating hood to restrict the heat generated by each heating unit, allowing it to flow vertically upwards and fully heat the noodles within the noodle frame of that unit. The heat does not diffuse outwards via convection, resulting in high heating efficiency. When there are few customers, no heating unit is used for cooking noodles; only a low base water temperature is maintained (e.g., around 90 degrees Celsius in low-altitude areas), requiring very low heating power. When the heating unit is cooking noodles and the temperature rises to a higher level, it produces a large amount of steam. At this point, the heating power can be reduced to minimize steam production. Due to the heat-concentrating hood, even a lower heating power is sufficient to keep the noodles tumbling and heated within the noodle frame, saving significant energy. The temperature-sensing thermocouple is directly welded to the bottom of the noodle-cooking tank, ensuring rapid temperature response and allowing for timely adjustments to heating power, further reducing energy consumption. The electromagnetic heating provides uniform power density, preventing scorching and scaling. After removing the heat-concentrating hood, the noodle-cooking tank has no dead corners, facilitating cleaning. The heating power is stable and unaffected by voltage fluctuations. The hot water in the noodle cooking tank heats the water in the preheating chamber. When adding water, the cold water first pushes the hot water in the preheating chamber to the noodle cooking area of ​​the noodle cooking tank, which can prevent the water temperature in the noodle cooking area of ​​the noodle cooking tank from suddenly dropping significantly, resulting in better cooking of noodles or dumplings.

Detailed Implementation

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "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 utility model 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 utility model.

[0035] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] This utility model aims to provide an energy-saving multi-heater noodle cooker, which includes at least a noodle cooking tank 11; multiple heating devices 17 are provided at the bottom of the noodle cooking tank, and the heating devices can be electric heating tubes or electromagnetic heating (similar to the principle of an induction cooker); a heat-concentrating cover 12 is provided in the noodle cooking tank for each heating device; since the heat-concentrating cover is placed in the noodle cooking tank, considering issues such as edibility, corrosion resistance and temperature, it is advisable to choose a metal material, such as stainless steel; for easy cleaning, the heat-concentrating cover is mostly detachable, or placed directly in the noodle cooking tank with a limiting alignment device; multiple heat-concentrating covers can also be connected into a whole by connectors 14, which makes it easier to remove and place. When the heat-collecting cover is below the water surface, there is no need to consider the water ingress problem. However, as the water level decreases with use, the water ingress problem needs to be considered. Therefore, it is advisable to set a water ingress channel in the lower section or lower end of the heat-collecting cover. For example, set one or more notches 13 at the lower end of the heat-collecting cover to form one or more water ingress channels. These notches are usually relatively small and can be designed according to the number of them. For example, they can be multiple 5*5 mm squares or multiple semicircles with a radius of 5-10 mm.

[0038] The aforementioned heat-concentrating cover can be designed with different structural forms as needed, such as... Figures 6 to 10 As shown, it can be cylindrical or square (e.g.) Figure 8 or Figure 9 As shown), trumpet-shaped (as shown) Figure 6 As shown), the double-horn tail section is a spliced ​​shape (as shown). Figure 1 As shown), the upper part is cylindrical or square, and the lower part is trumpet-shaped (as shown). Figure 7 As a variation, it can also be like... Figure 10 As shown, the noodle cooking tank is divided into multiple chambers by partitions, and a heating device is installed in each chamber.

[0039] The material of the noodle cooking tank can be selected according to needs. For heating devices with electric heating tubes, the range of options is relatively wide, such as aluminum and stainless steel. For electromagnetic heating devices, it is necessary to select ferromagnetic materials suitable for electromagnetic heating, or composite metal materials such as three-layer composite materials, where the inner layer is a material that can directly contact food, such as 304 stainless steel, the middle layer is a material with high thermal conductivity, such as aluminum or copper, and the outer layer is a material suitable for electromagnetic heating, such as carbon steel.

[0040] Example 1

[0041] like Figure 1 As shown, multiple heating devices 17, which are electric heating tubes, are installed below the bottom of the noodle cooking tank 11. A heat-concentrating cover 12 is installed inside the noodle cooking tank corresponding to each heating device. Generally, a water inlet hole is provided near the bottom or lower end of the heat-concentrating cover to facilitate water flow. A water inlet pipe 29 is installed on one side of the noodle cooking tank; a valve 27 is installed on the water inlet pipe 29 for adding water to the noodle cooking tank. The upper end of the heat-concentrating cover is generally located near the water surface.

[0042] Example 2

[0043] like Figure 2 As shown, multiple heating devices 17 are installed at the bottom of the noodle cooking tank 11. Each heating device 17 is an electromagnetic heating coil powered by a high-frequency power supply, generating eddy current heating at the bottom of the noodle cooking tank 11. A heat-concentrating cover 12 is installed corresponding to each heating device within the noodle cooking tank. A notch 13 is provided at the bottom of the heat-concentrating cover 12 to allow communication between the inside of the heat-concentrating cover and the water in the noodle cooking tank. Adjacent heat-concentrating covers are connected as a single unit by connectors 14 for easy removal and placement. A water inlet pipe 29 is installed on one side of the noodle cooking tank; a valve 27 is installed on the water inlet pipe 29.

[0044] A partition 18 is installed on one side of the noodle cooking tank's inlet pipe, dividing the tank into two chambers: a heating chamber on the left and a preheating chamber 19 on the right. At least the bottom of the partition has a connecting hole or a small gap between it and the bottom plate to maintain water level balance between the two chambers. This allows the water entering the tank to preferentially supply the preheating chamber. After being preheated, most of the preheated water overflows into the heating chamber through the top of the partition. This effectively prevents low-temperature water from flowing directly around or inside the nearby heat-collecting hood, which could significantly affect the water temperature there. The upper part of the heat-collecting hood is generally located below the water surface, close to it; the height of the partition is approximately the same as the height of the heat-collecting hood.

[0045] To facilitate water level control, a high water level sensor 20 and a low water level sensor 24 are installed in the preheating chamber. The valve 27 is a solenoid valve, and the opening and closing of the valve 27 are controlled by the two water level sensors.

[0046] Example 3

[0047] like Figures 3 to 5 As shown, this embodiment of an energy-saving multi-eye noodle cooker includes...

[0048] The supporting frame consists of a lower longitudinal beam 2, a column 4, a crossbeam 7 supporting the noodle cooking tank, a longitudinal beam 8 supporting the noodle cooking tank, an upper crossbeam 21, and an upper longitudinal beam 22; the supporting frame is covered with a metal plate as an outer shell 3; and a footplate 1 is provided at the bottom of the supporting frame.

[0049] The support frame is divided into upper and lower layers; the noodle cooking tank 11 is installed on the left and right noodle cooking tank support beams 7 and the front and rear noodle cooking tank support longitudinal beams 8; the lower layer is the equipment layer used to install high-frequency power supply cooling fans 30, high-frequency power supplies 32, etc.

[0050] The heating device 17 is an electromagnetic heating coil and is electrically connected to the high-frequency power supply 32.

[0051] The noodle cooking tank 11 is mounted on the left and right supporting crossbeams 7 and the front and rear supporting longitudinal beams 8. An overflow ditch 10 is provided around the outer perimeter of the upper section of the noodle cooking tank 11 to prevent excessive water intake due to high water level sensor failure. An overflow pipe 35 is connected to the overflow ditch 10. A drain pipe 34 is provided at one corner of the bottom of the noodle cooking tank 11, and a drain valve 6 is installed on the drain pipe 34 to drain wastewater during cleaning. Multiple electromagnetic heating coils 17 are distributed below the bottom plate of the noodle cooking tank 11 after the bottom insulation layer 15 is installed. A temperature sensor 16 is installed near the edge of each electromagnetic heating coil 17. A fan cooling fan is installed below the electromagnetic coils via a fan baffle 5. Fan 28 is used to dissipate heat from the electromagnetic coil; multiple heat-collecting covers 12 are distributed inside the noodle cooking tank 11, positioned directly above the corresponding electromagnetic heating coils. The bottom of the heat-collecting cover 12 has a bottom notch 13. All heat-collecting covers are welded into a whole heat-collecting cover assembly using heat-collecting cover connectors 14; water inlet pipe 29 is located on one side of the noodle cooking tank 11 near the bottom, and water inlet solenoid valve 27 is installed on the water inlet pipe 29; a preheating chamber partition 18 is installed on one side of the heat-collecting cover assembly. The preheating chamber partition 18 and the side plate on the water inlet side of the noodle cooking tank 11 form a preheating chamber 19. There is a gap between the preheating chamber partition 18 and the bottom plate of the noodle cooking tank 11, or a notch or hole can be made at the bottom of the preheating chamber partition 18.

[0052] For ease of control, microcontrollers or PLCs are typically used as control devices to achieve automatic control of temperature and water intake; for example... Figure 11 As shown, the operating switch, water level sensor, and temperature sensor for each heating device are connected to the input terminal of the control device. The control device controls the various high-frequency power supplies connected to the output terminal based on the operating switch and these sensors to drive the electromagnetic heating coils connected to them, thereby controlling the heating. It also controls the water inlet valve, etc. The operating switch and control device can be housed in the control box 9 on the outside of the outer casing.

[0053] Preferably, the temperature sensor 16 is a thermocouple sensor and is directly welded to the bottom plate of the noodle cooking tank 11.

[0054] Preferably, a cover is provided at the upper end of the noodle cooking pool 11, with an opening directly opposite each heat-concentrating hood 12. The opening size is slightly larger than the size of the noodle frame to reduce heat loss.

[0055] The working principle of the energy-saving multi-eye noodle cooker of this utility model embodiment is as follows:

[0056] Close the drain valve 6 and turn on the power switch. When the water level is below the high water level, the control system opens the inlet solenoid valve 27 to add water. When the water level is below the minimum water level, heating is not activated. When the water level is above the minimum water level, all electromagnetic heating is activated. The high-frequency power supply 32 generates a high-frequency current in the electromagnetic heating coil 17. The high-frequency current generates a high-frequency magnetic field around the electromagnetic heating coil 17. The high-frequency magnetic field induces eddy currents in the bottom plate of the noodle cooking tank, causing the bottom plate to heat up. The heated bottom plate then heats the water in the noodle cooking tank 11. When the water level reaches the high water level, the control system closes the inlet solenoid valve 27, stops adding water, and continues heating. When each unit reaches the set preheating temperature, heating stops, and the unit enters standby mode. Once the temperature drops below the set preheating temperature, the heating unit is activated again, repeating this process to maintain a baseline water temperature (around 70-90 degrees Celsius) using lower heating power. Each heating unit is independently controlled. When noodles need to be cooked, the operator signals the control system, which then activates the corresponding unit (other units remain in standby mode). A noodle frame is placed in the frame, and once the set temperature is reached (displayed on the system), the operator adds noodles. The temperature then decreases. When the temperature rises again to the set cooking temperature, the heating power is reduced to minimize steam generation, and the control system starts timing. After the set time is reached, the system returns to standby mode, and the operator removes the noodle frame, repeating the process. All heating units are independently controlled, and due to the presence of the heat-concentrating hood, heat does not diffuse outwards via convection. When other units are in standby mode, it does not affect the heating of this unit.

[0057] Meanwhile, the water in the noodle-cooking zone slowly heats the water in the preheating chamber 19, causing the water temperature in the preheating chamber 19 to gradually rise. During the noodle-cooking process, the water level drops. When the water level falls below the maximum water level, the control system opens the inlet solenoid valve 27 to replenish water. After the cold water enters the preheating chamber 19, the hot water in the preheating chamber 19 overflows from the top into the noodle-cooking zone. Because the temperature of the hot water entering the noodle-cooking zone is relatively high, the water temperature drop in the noodle-cooking zone is minimal, thus having little impact on the noodle-cooking process. After the water level reaches the maximum water level, the control system closes the inlet solenoid valve 27 to stop replenishing water. The small gap between the preheating chamber partition 18 and the bottom plate of the noodle-cooking tank 11 ensures that the water levels on both sides are balanced when no water is added.

[0058] During the heating process, water can be replenished into the heat-concentrating cover 12 through the bottom notch 13.

[0059] During the cooking process, the overflowing water flows through the overflow ditch 10 to the overflow pipe 35 and is discharged into the sewer.

[0060] Water needs to be added to the noodle cooking basin 11. Open the drain valve 6.

[0061] The noodle cooking tank 11 needs to be cleaned by removing the heat-concentrating hood assembly. Since the inside of the noodle cooking tank 11 has no hard-to-reach areas, cleaning is easy.

[0062] The electromagnetic heating power is evenly distributed, preventing the soup from sticking to the pot. Scale buildup on the bottom plate will not affect the electromagnetic heating process. Therefore, frequent cleaning is not required.

[0063] Electromagnetic heating power is not affected by voltage changes, resulting in good repeatability and stability in noodle cooking, and better standardization.

[0064] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Many other changes and modifications made without departing from the concept and scope of the present invention should be considered within the protection scope of the present invention.

[0065] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
