Description

Technical Field

[0001] This utility model relates to a heating device, specifically a heating device for rice noodle processing, and a rice noodle microwave heating and cooking device and a rice noodle machine having the device. Background Technology

[0002] Rice noodles are a type of rice product made from rice through processes such as soaking, steaming, and pressing. Rice noodle machines use a heating and cooking device to cook the moist rice flour and extrude it into strips or strands.

[0003] The existing structure used in rice noodle machines for the cooking process usually involves setting a heating component on the outer wall of the extrusion cylinder of the extrusion part in the heating and cooking device. Through heat conduction, the powdery material inside the extrusion cylinder is heated "from the outside in" to achieve the heating and cooking of the moist powdery material.

[0004] The extrusion cylinder in the heating and cooking device of a rice noodle machine commonly uses heat conduction heating, and its structure mainly includes three types:

[0005] The first type is electric heating: the electric heating component is set on the outer wall of the extrusion cylinder. The heat energy generated by the electric heating resistance wire or electric heating tube of the electric heating component is first transferred to the extrusion cylinder, and then the heat energy is transferred from the extrusion cylinder to the material inside the extrusion cylinder. The temperature of this heating method is easy to control, but it dissipates heat quickly, is inefficient, and consumes a lot of energy.

[0006] The second method is heat transfer oil heating: A heat transfer oil heating assembly is installed on the outer wall of the extrusion cylinder of the extrusion unit. Heat transfer oil is used as the heat carrier, and heat is transferred to the extrusion cylinder through the circulation of electrically heated heat transfer oil. Its advantages are uniform temperature and stable heating; however, the structure of the heat transfer oil heating assembly is relatively complex, and it requires maintaining the quality of the heat transfer oil and the normal operation of the circulation system.

[0007] The third method is steam heating: a steam heating component is installed on the outer wall of the extrusion cylinder of the extrusion unit, using the heat energy of steam to heat the extrusion cylinder. This method can transfer heat energy evenly, but the equipment installation is complex, requiring the installation of a steam generator and connection to steam supply pipelines, etc.

[0008] These heating methods all involve heating the extrusion cylinder of the extrusion component, and heating and cooking the material inside the cylinder through heat conduction. These heating methods result in the outer wall of the extrusion cylinder being hot while the temperature inside the cylinder is low, leading to uneven heating and temperature lag. This results in low heating efficiency, high energy consumption, and uneven heating of the material, thus affecting the quality of the rice noodles. Utility Model Content

[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a microwave heating and cooking device for rice noodles and a rice noodle machine equipped with the device.

[0024] The forming head is located on the side wall of the rice noodle extrusion end of the extrusion cylinder and communicates with the inner cavity of the inner cylinder.

[0026] The splined shaft is used to connect the extrusion screw and the power mechanism, and one end of the splined shaft is fixedly connected to one end of the hollow shaft.

[0027] Furthermore, it includes a motor, a flange, and a bearing housing. The flange is used to connect the extrusion cylinder and the bearing housing. One end face of the flange is fixedly connected to the feed end face of the extrusion cylinder, and the other end face of the flange is connected to the bearing housing.

[0030] The main control module is a PLC, which is powered by a power supply module.

[0031] A rice noodle machine with a microwave heating device includes the above-mentioned rice noodle microwave heating and cooking device.

[0032] During the process of material being pushed between the inner cylinder and extrusion blades of the extrusion component by the extrusion screw, when the temperature sensor detects that the temperature of the extrusion cylinder is lower than the minimum set value, the main control module controls the power controller to perform microwave heating through the magnetron of the microwave heating component, so that the internal temperature of the extrusion cylinder can be rapidly raised to the set value; when the temperature sensor detects that the internal temperature of the extrusion cylinder exceeds the maximum set value, the main control module controls the cooling component to perform cooling, so that the internal temperature of the extrusion end and the forming head of the extrusion cylinder drops to the set value; thus, the temperature inside the extrusion cylinder and the forming head can be effectively controlled, accelerating the cooking of rice noodles and the forming of rice noodle strips.

[0052] The present invention will be further described below with reference to the embodiments and accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention. Example

[0053] like Figures 1-5 As shown, a microwave heating and cooking device for rice noodles includes an extrusion component 1, which includes an extrusion cylinder 2-2, and a microwave heating component 4, which is disposed on the outer wall of the extrusion cylinder 2-2.

[0054] The microwave heating assembly 4 includes a magnetron 4-1, which is used to generate microwaves;

[0055] The extrusion component 1 includes a barrel assembly 2 and an extrusion screw 3. The barrel assembly 2 includes an inner cylinder 2-3 and an extrusion cylinder 2-2.

[0056] The inner cylinder 2-3 is used to isolate materials and prevent material leakage; the inner cylinder 2-3 is made of a material that does not absorb microwaves; the inner cylinder 2-3 is in the shape of a round tube, and the side wall of the feeding end of the inner cylinder 2-3 is provided with a feeding port 2-3-1;

[0057] The extrusion cylinder 2-2 is made of metal. The feed end sidewall of the extrusion cylinder 2-2 is provided with a feed pipe 2-4 that communicates with the inner cavity of the extrusion cylinder 2-2. The sidewall of the extrusion cylinder 2-2 is provided with multiple microwave inlets 2-2-1.

[0058] The extrusion screw 3 is used to push materials. The extrusion screw 3 includes a hollow shaft 3-2 and an extrusion blade 3-3. The extrusion blade 3-3 is in the shape of a straight cylindrical spiral. The hollow shaft 3-2 passes through and is embedded in the inner cavity of the hollow extrusion blade 3-3 and is fixedly connected to the extrusion blade 3-3.

[0059] The inner cylinder 2-3 is disposed inside the extrusion cylinder 2-2. The outer side wall of the inner cylinder 2-3 is attached to the inner side wall of the extrusion cylinder 2-2. The two ends of the inner cylinder 2-3 are flush with the two ends of the extrusion cylinder 2-2. The feed port 2-3-1 of the inner cylinder 2-3 is connected to the feed pipe 2-4. The extrusion screw 3 is disposed in the inner cavity of the inner cylinder 2-3. Each inlet 2-2-1 on the extrusion cylinder 2-2 is equipped with a microwave heating component. The inlet 2-2-1 is fixedly connected to the magnetron 4-1, and the magnetron 4-1 is fixed to the outer wall of the extrusion cylinder 2-2.

[0060] Furthermore, the microwave heating assembly 4 also includes a waveguide 4-2, which is used to transmit microwaves generated by the magnetron 4-1; the transmitting end of the magnetron 4-1 is connected to the input port of the waveguide 4-2; the inlet port 2-2-1 is connected to the output port of the waveguide 4-2; and the magnetron 4-1 is fixed on the extrusion cylinder 2-2 through the waveguide 4-2.

[0061] A waveguide flange 2-5 is provided on the inlet 2-2-1. The waveguide 4-2 is connected to the waveguide flange 2-5 to fix the magnetron 4-1 on the outer wall of the extrusion cylinder 2-2.

[0063] Furthermore, the magnetrons 4-1 are arranged radially and staggered on the extrusion cylinder 2-2. This avoids the formation of standing waves or interference effects from microwaves emitted by adjacent magnetrons within the cylinder, reducing localized overheating or weak field areas caused by energy superposition. This allows microwave energy to penetrate the material more evenly, achieving synchronous heating both inside and outside, eliminating the "external burning and internal rawness" phenomenon common in traditional heating methods. During the rotation of the extrusion screw 3, which pushes the material, the staggered magnetrons can heat different parts of the material from multiple angles, reducing heating blind spots caused by material flow and ensuring uniform curing during continuous production.

[0064] Furthermore, it includes a heat insulation layer 2-8, which covers the outer wall of the extrusion cylinder 2-2 to reduce temperature fluctuations inside the extrusion cylinder 2-2.

[0065] Furthermore, a temperature sensor 2-9 is included, which is disposed on the outer wall of the extrusion cylinder 2-2 for detecting the temperature of the extrusion cylinder 2-2.

[0066] Preferably, the inner cylinder 2-3 is made of polytetrafluoroethylene (PTFE), which can be used for extended periods at temperatures ranging from -180°C to 260°C, and its melting temperature ranges from 327°C to 342°C. When heated in microwaves, it maintains a stable chemical structure and will not produce harmful substances or deform due to microwave radiation.

[0067] The hollow shaft 3-2 is made of metal, and the extrusion blade 3-3 is made of polytetrafluoroethylene.

[0068] Furthermore, a cooling component 5 is included, which is disposed on the outer wall of the extrusion cylinder 2-2, located at the rice flour extrusion end of the extrusion cylinder 2-2. The cooling component 5 adopts an existing circulating water cooling device.

[0069] Furthermore, it includes a rotating shaft 3-4, a forming head 2-7, a locking disc 2-6, and a splined shaft 3-1;

[0070] The forming head 2-7 is located on the side wall of the rice flour extrusion end of the extrusion cylinder 2-2 and communicates with the inner cavity of the inner cylinder 2-3;

[0071] The locking disc 2-6 is fixed on the port of the rice noodle extrusion end of the extrusion cylinder 2-2 to seal the extrusion end port of the extrusion cylinder 2-2; the rear section of the rotating shaft 3-4 is fixedly connected to the hollow shaft 3-2 of the rice noodle extrusion end, and the front section of the rotating shaft 3-4 is rotatably connected to the locking disc 2-6 to support the rotational movement of the extrusion screw 3.

[0072] The splined shaft 3-1 is used to connect the extrusion screw 3 and the power mechanism, and one end of the splined shaft 3-1 is fixedly connected to one end of the hollow shaft 3-2.

[0073] Furthermore, it includes a motor 7, a flange 2-1, and a bearing seat 6. The flange 2-1 is used to connect the extrusion cylinder 2-2 and the bearing seat 6. One end face of the flange 2-1 is fixedly connected to the feed end face of the extrusion cylinder 2-2, and the other end face of the flange 2-1 is connected to the bearing seat 6. The rotating shaft of the motor 7 is connected to the other end of the spline shaft 3-1 through the bearing seat 6 to drive the extrusion screw 3 to rotate.

[0074] like Figure 6 As shown, the system includes a controller, which comprises a main control module and an input module and an output module electrically connected thereto; the temperature sensors 2-9 are electrically connected to the input module; the motor driver, power controller, and refrigeration component 5 are electrically connected to the output module.

[0076] The main control module is a PLC, which is powered by the power supply module.

[0077] A rice noodle machine with a microwave heating device includes the aforementioned microwave heating and cooking device for rice noodles. When installed with an existing rice noodle machine, the extrusion and heating devices of the existing rice noodle machine are removed and replaced with this microwave heating and cooking device. The discharge pipe of the existing rice noodle machine is connected to the inlet pipe 2-4 of this device, allowing the rice slurry to enter the inner cylinder 2-3 and the extrusion blades 3-3 through the inlet 2-3-1. The motor 7 drives the extrusion screw 3 to rotate, pushing the rice slurry from the inlet end to the rice noodle extrusion end within the inner cylinder 2-3, and extruding it from the forming head 2-7 to form strips or strands of rice noodles. During this process, when the temperature sensor 2-9 detects that the temperature of the extrusion cylinder 2-2 is lower than the set minimum value, the main control module controls the power controller to activate the magnetic... Microwave heating is performed by control tube 4-1 to rapidly raise the internal temperature of extrusion cylinder 2-2 to the set value. When temperature sensor 2-9 detects that the internal temperature of extrusion cylinder 2-2 exceeds the maximum set value, the main control module controls the cooling component 5 to perform cooling and simultaneously controls the magnetron to stop microwave heating, cooling the extrusion end of extrusion cylinder 2-2, so that the internal temperature of extrusion end of extrusion cylinder 2-2 and forming head 2-7 drops to the set value. This effectively controls the internal temperature of extrusion cylinder 2-2 and forming head 2-7, and the coordinated control realizes the fully automated management of the entire process from emergency cooling to steady-state maintenance, accelerating the cooking of rice noodles and the forming of rice noodle strips.

[0078] Alternatively, the bearing housing of the existing rice noodle machine can be fixedly connected via flange 2-1, and the motor of the existing rice noodle machine can still be used. The motor can be connected to the power connection end of the spline shaft 3-1 via a gearbox, which makes it easy to adjust the speed of the extrusion screw 3.

[0079] This device has a compact overall structure and is easy to install. It can be easily installed without complicated tools.

[0080] This microwave heating and cooking device for rice noodles can easily replace the extrusion cooking component of existing rice noodle machines, forming a rice noodle machine with a microwave heating device. This achieves the technical effect of heating the powder material inside and out simultaneously in a shorter time, with short heating time and fast speed.

[0081] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
