Description

Technical Field

[0001] This utility model relates to the field of microwave processing equipment technology, specifically a microwave processing equipment based on rice and flour food fermentation. Background Technology

[0002] Existing microwave processing equipment has several shortcomings in the microwave processing of fermented rice and flour products. Firstly, during microwave processing, the moisture in the fermented rice and flour products evaporates upon heating and condenses into droplets inside the microwave chamber. These droplets easily drip onto the food surface, affecting not only its appearance but also potentially causing uneven heating and impacting processing quality and taste. However, most existing microwave processing equipment lacks effective moisture collection and drainage structures, making it impossible to properly handle the condensed water droplets. Secondly, the installation of replaceable components (such as liquid storage boxes) in existing equipment typically employs relatively simple fixing methods. Over long-term use, these components are prone to loosening or even detachment, and installation and disassembly are not convenient, hindering equipment maintenance and repair. Furthermore, poor sealing during component installation can lead to microwave leakage and other safety hazards. Therefore, a new microwave processing equipment based on fermented rice and flour products is urgently needed to solve these problems. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] In this technical solution, a microwave processing device based on rice and flour food fermentation includes a microwave processing machine 1. The microwave processing machine 1 has a rotating platform 3 installed inside its microwave chamber, and liquid storage boxes 5 installed on the inner walls of both sides of the microwave chamber. Water receiving plates 8 are installed on the upper left and right sides of the microwave chamber, arranged in a V-shape. The outer ends of the water receiving plates 8 are located at the top opening of the liquid storage boxes 5. A flow guide plate 6 is installed at the top of the two water receiving plates 8. Mounting platforms 10 are installed on the inner walls of both sides of the microwave processing machine 1. Slide tracks 11 are opened on the side walls of the mounting platforms 10, and sliders 12 are installed on the side walls of the liquid storage boxes 5, with the sliders 12 installed within the slide tracks 11.

[0023] Microwave processing machine 1, as the core of the entire equipment, provides the basic operating environment for the microwave processing of rice and flour products. It is internally equipped with key components such as a magnetron that generates microwaves, converting electrical energy into microwave energy to heat and process the food. Typically, the rated power of this type of microwave processing machine is...

[0024] The range [X]W-[X]W is used to meet different processing needs. For example, for microwave heating of fermented rice and flour products, 800W-1200W is common, which can bring the food to the appropriate processing temperature in a short time.

[0025] Assuming the microwave processing machine 1 has a rated power of 1000W and a microwave frequency of 2450MHz, which is a frequency commonly used in household and common industrial microwave processing equipment, it can be effectively absorbed by water molecules in food to achieve efficient heating.

[0026] The microwave processing machine 1 should be equipped with a temperature control system, which can use temperature sensors such as thermistors to monitor the internal temperature of the microwave chamber in real time and adjust the output power of the magnetron through a feedback circuit to ensure precise control of the processing temperature. For example, the temperature control accuracy can be set to ±[X]℃ to meet the strict temperature requirements for rice and flour food processing. Simultaneously, a microwave leakage protection device should be installed, such as using a multi-layer metal shielding structure and sealing strips at the oven door, to ensure that the microwave leakage meets national safety standards, with the leakage per square centimeter not exceeding [specific value] μW / cm². 2 ;

[0027] The turntable 3 plays a crucial role inside the microwave chamber in supporting rice and flour products and ensuring they are heated evenly. Driven by a motor, it rotates the food placed on it 360 degrees within the microwave field, ensuring that all parts of the food receive sufficient and even microwave irradiation, preventing uneven heating in certain areas. Generally, the rotation speed of the turntable 3 can be adjusted within a certain range to accommodate the processing needs of different types and volumes of rice and flour products.

[0028] The diameter of the turntable 3 is designed to be [X] cm, which can meet the placement needs of common plates and rice and flour food containers of different sizes. The motor drives its speed range of [X]-[X] revolutions per minute. For example, for small, regularly shaped rice and flour food, the speed can be set to 10-15 revolutions per minute; for larger or irregularly shaped food, the speed can be appropriately reduced to 5-10 revolutions per minute to ensure uniform heating.

[0029] The turntable 3 should have an anti-slip design, with rubber anti-slip pads or raised textures on its surface to increase friction with food containers and prevent them from sliding or tipping over during rotation. At the same time, to accommodate food of varying weights, the load-bearing capacity of the turntable 3 needs to be clearly defined, for example, its maximum load capacity of [X] kg, to ensure the stability and safety of the equipment operation.

[0030] The liquid collection box 5 is mainly used to collect water droplets formed by condensation after food evaporation during microwave processing. It is installed on the inner walls of the left and right sides of the microwave chamber, and its position is carefully designed to effectively collect water flowing down from the drip tray 8. The liquid collection box 5 is generally made of corrosion-resistant and high-temperature-resistant materials to adapt to the working environment inside the microwave chamber.

[0031] The liquid storage box 5 is designed with a volume of [X] mL, which can be adjusted according to the amount of moisture generated during actual processing. For example, when processing rice and flour products with high moisture content on a large scale, the volume of the liquid storage box can be appropriately increased to 500 mL-1000 mL to reduce the number of cleaning times. It can be made of food-grade PP (polypropylene) plastic, which has good chemical corrosion resistance and high temperature resistance, and can be used stably for a long time in the high-temperature environment inside the microwave oven.

[0032] The liquid storage box 5 should be equipped with a liquid level detection device, such as a float-type liquid level sensor. When the water level in the liquid storage box reaches a certain height, a signal should be sent to the external control system via circuit connection to remind the operator to clean the liquid storage box in time to prevent water overflow. In addition, the bottom of the liquid storage box 5 should be designed with a drain outlet. The drain outlet can be fitted with a pipe with a sealing plug to facilitate the drainage of liquid in the box during cleaning. The diameter of the drain outlet can be set to [X] mm to ensure smooth drainage.

[0033] The "V" shape of the drip tray 8 is designed to better collect condensed water droplets and guide them to flow to both sides. It is typically made of a material with good thermal conductivity and low water accumulation, ensuring that the water droplets slide off quickly. The drip tray 8 is installed at the upper part of the microwave chamber, a high position that effectively intercepts water vapor that condenses upon rising.

[0034] The water collection plate 8 has a length of [X] cm and a width of [X] cm, adapted to the size of the microwave chamber. For example, for a common microwave chamber with an internal size of 40 cm long and 30 cm wide, the length of the water collection plate can be set to 25 cm-30 cm and the width to 10 cm-15 cm, which can cover a sufficient area to collect water droplets without affecting the internal spatial layout of the microwave chamber. Its angle with the horizontal direction is [X] degrees, generally between 30 and 45 degrees. This angle range ensures that the water droplets flow smoothly to the liquid storage box 5 under the action of gravity.

[0035] The surface of the water collection plate 8 should be specially treated, such as by using a hydrophilic coating, to further reduce the adhesion of water droplets to its surface, making the water droplets easier to slide off and reducing water accumulation. At the same time, the connection between the water collection plate 8 and the inner wall of the microwave oven should be sealed to prevent water droplets from leaking from the connection. High-temperature resistant sealant can be used for sealing.

[0036] This design ensures that the water droplets collected by the receiving plate 8 flow accurately into the storage box 5. To ensure smooth water flow, the joint between the outer end of the receiving plate 8 and the top opening of the storage box 5 should be designed to be tight and smooth to avoid water blockage or splashing.

[0037] The gap between the outer end of the water receiving plate 8 and the top opening of the liquid storage box 5 should be controlled within [X] mm, for example, 0.5 mm-1 mm, and the fitting accuracy should be ensured through precise manufacturing process. The width of the top opening of the liquid storage box 5 should be slightly larger than the width of the outer end of the water receiving plate 8, generally [X] mm wider, to facilitate installation and ensure the water collection effect, such as 5 mm-10 mm wider.

[0038] At the junction of the outer end of the water receiving plate 8 and the top opening of the liquid storage box 5, a guide groove can be set to guide water droplets to flow into the liquid storage box 5 in a more concentrated manner. The depth of the guide groove is [X] mm, for example, 3 mm-5 mm. The width of the groove is adapted according to the width of the outer end of the water receiving plate to enhance the stability and efficiency of drainage.

[0039] The drainage plate 6 is installed at the top of the microwave chamber and at the top of the two water receiving plates 8. Its function is to collect and drain water droplets condensed at the top of the microwave chamber, as well as some water droplets splashed from the water receiving plates 8 or not flowing down in time, so that the water droplets flow along the drainage plate 6 into the water receiving plates 8 and then into the liquid storage box 5. The drainage plate 6 is usually made of a similar material to the water receiving plates 8 to ensure stable performance in high-temperature environments.

[0040] The size of the drainage plate 6 is designed based on the space at the top of the microwave chamber and the position of the water collection plate 8. Its length can cover the distance between the tops of the two water collection plates 8 and exceed it by [X] cm, for example, by 5-10 cm. The width is [X] cm, generally between 15-20 cm, to ensure effective water droplet collection. Its surface can be designed with a certain slope of [X] degrees, such as 5-10 degrees, to facilitate water droplet sliding.

[0041] The connection between the drainage plate 6 and the top of the microwave chamber and the water receiving plate 8 should also be sealed to prevent water droplet leakage. At the same time, some tiny grooves or textures can be made on the surface of the drainage plate 6 to further guide the water droplets to the water receiving plate 8. The groove depth is [X] mm and the width is [X] mm. For example, the groove depth is 0.5 mm-1 mm and the width is 1 mm-2 mm, and they are distributed on the surface of the drainage plate at certain intervals.

[0042] The mounting platform 10, through the cooperation of the slide rail 11 and the slider 12, enables convenient installation and removal of the liquid storage box 5, facilitating operation during equipment maintenance or cleaning of the liquid storage box. The mounting platform 10 is fixed to the inner walls of the left and right sides of the microwave chamber, providing stable support and sliding tracks for the liquid storage box 5. The design of the slide rail 11 and the slider 12 should ensure smooth sliding and prevent shaking or falling off during equipment operation.

[0043] The length of the slide 11 is designed according to the height of the liquid storage box 5, and is generally [X] cm longer than the height of the liquid storage box 5, for example, 5cm-10cm longer, to ensure that the liquid storage box 5 can be fully inserted and removed. The width of the slide 11 is adapted to the width of the slider 12, and the gap is controlled within [X] mm, for example, 0.2mm-0.5mm, to ensure smooth and stable sliding. The material of the slider 12 can be a wear-resistant engineering plastic, such as POM (polyoxymethylene), which has good wear resistance and self-lubricating properties, can reduce friction with the slide 11, and extend service life;

[0044] To prevent the liquid storage box 5 from accidentally sliding out during equipment operation due to vibration or other reasons, a limiting device, such as a limit block, can be installed at the end of the slide rail 11. The limit block can be made of metal and fixed to the end of the slide rail 11 with screws. Its height should be sufficient to effectively prevent the slider 12 from sliding out, and the height should be [X] mm, for example, 8 mm-10 mm. At the same time, a lubricant, such as high-temperature resistant silicone oil, can be added between the slider 12 and the slide rail 11 to further reduce frictional resistance and ensure smooth sliding.

[0045] In some technical solutions, mounting screw holes are provided at both the upper and lower ends of the side wall of the mounting plate 10, and mounting screw grooves are provided on the side wall of the microwave processing machine 1 at the mounting screw holes. Bolt bodies are screwed into the mounting screw holes and mounting screw grooves.

[0046] This bolted connection method provides a reliable connection for fixing the mounting plate 10 to the microwave processing machine 1. By opening mounting screw holes and mounting screw grooves at corresponding positions on the mounting plate 10 and the microwave processing machine 1, and using bolts for screwing, the stability of the mounting plate 10 during equipment operation can be ensured, and it can withstand the forces such as the liquid storage box 5 and possible vibrations.

[0047] The diameter of the mounting screw hole and mounting screw groove is generally determined based on the overall structure of the equipment and the force required to withstand, and is commonly [X] mm, for example, 6mm-8mm. The length of the bolt body should be selected based on the sum of the thickness of the mounting plate 10 and the side wall of the microwave processing machine 1. Generally, it is necessary to ensure that the bolt has sufficient thread engagement length after being screwed in. For example, if the bolt body length is [X] mm, it should be 5mm-10mm longer than the sum of the thicknesses of the two.

[0048] To enhance the sealing of the connection and prevent bolt loosening, sealing washers and spring washers can be used at the connection between the bolt body and the mounting bolt hole or groove. Sealing washers can be made of rubber with a thickness of [X] mm, for example, 1mm-2mm, to prevent external dust, moisture, etc., from entering the equipment and affecting its performance. Spring washers provide a reverse elastic force to maintain the bolt's tightness when the bolt tends to loosen due to vibration or other reasons during equipment operation.

[0049] In some technical solutions, a circular groove 131 is provided at the bottom end of the bolt body 13, and a bolt rod 133 is installed inside the circular groove 131. The bolt rod 133 is screwed into the mounting screw hole and the mounting screw groove.

[0050] This design makes the structure of the bolt body 13 more flexible. Through the cooperation between the circular groove 131 and the bolt shank 133, it can better adapt to different installation positions and angle fine-tuning requirements during installation. The bolt shank 133, as the part that directly connects to the mounting screw hole and mounting screw groove, bears the main fastening function;

[0051] The diameter of the circular groove 131 is [X] mm, for example, 8mm-10mm, and the depth is [X] mm, for example, 5mm-8mm, to ensure that the bolt rod 133 can be stably installed therein with a certain amount of room for movement. The diameter of the bolt rod 133 is adapted to the mounting screw hole and mounting screw groove, and is generally [X] mm smaller than the diameter of the screw hole, for example, 0.5mm-1mm. The thread length is determined according to the installation requirements to ensure sufficient engagement length, such as a thread length of [X] mm, 10mm-15mm.

[0052] In some technical solutions, a retaining ring 136 is installed on the upper outer end of the bolt rod 133, and an annular pressure plate 135, a spring 137 and an annular rubber sheet 132 are fitted on the circumferential surface of the bolt rod 133.

[0053] The retaining ring 136 is used to limit the position of the annular pressure plate 135, spring 137, and annular rubber sheet 132, keeping them stable on the bolt rod 133. The annular pressure plate 135 can evenly transmit the elastic force of the spring 137 to the annular rubber sheet 132, which in turn serves to seal and dampen vibrations. The spring 137 provides continuous elastic force, ensuring that the bolted connection remains tight and prevents loosening even during equipment operation and in the event of vibrations.

[0054] The inner diameter of the retaining ring 136 is matched with the outer diameter of the bolt rod 133, with the gap controlled within [X] mm, for example, 0.1 mm-0.3 mm. The outer diameter is determined according to the overall structural design, generally [X] mm, such as 15 mm-20 mm. The thickness of the annular pressure plate 135 is [X] mm, for example, 2 mm-3 mm, and its diameter is slightly larger than the outer diameter of the spring 137, generally [X] mm larger, such as 5 mm-8 mm. The elastic coefficient of the spring 137 is selected according to the required tightening force and vibration reduction requirements of the equipment, for example, the elastic coefficient is [X] N / mm, 5 N / mm-10 N / mm. The thickness of the annular rubber sheet 132 is [X] mm, such as 3 mm-5 mm, and its diameter is similar to that of the annular pressure plate 135, ensuring effective sealing and vibration reduction.

[0055] The material of the annular rubber sheet 132 should be a high-temperature resistant, aging-resistant rubber material with good sealing performance, such as silicone rubber. Meanwhile, to further enhance the rust resistance of the spring 137, its surface can be galvanized or treated with other rust-proofing methods to extend the spring's service life and ensure a continuous and stable supply of elastic force during long-term use.

[0056] In some technical solutions, an extrusion block 134 is installed at the upper edge of the annular rubber sheet 132, and an arc surface 138 is provided on the outer wall of the bolt body 13, and the surface of the arc surface 138 is provided with anti-slip texture.

[0057] When the annular rubber sheet 132 is subjected to pressure from the spring 137, the compression block 134 can concentrate the pressure on a specific area, enhancing the sealing effect. The arc surface 138 on the outer wall of the bolt body 13 is designed for easy hand operation, while the anti-slip texture increases the friction when holding the hand, making installation and disassembly operations more convenient and safer.

[0058] The height of the extrusion block 134 is [X] mm, for example, 3mm-5mm, and the width is adapted to the edge width of the annular rubber sheet 132, generally [X] mm, such as 8mm-10mm. The radius of the arc surface 138 is [X] mm, for example, 10mm-15mm, the depth of the anti-slip texture is [X] mm, such as 0.5mm-1mm, and the width is [X] mm, 1mm-2mm, evenly distributed on the surface of the arc surface 138 at a certain interval;

[0059] The extrusion block 134 can be made of high-hardness and wear-resistant plastic or metal materials, such as aluminum alloy, to ensure that it will not deform due to extrusion during long-term use. The anti-slip texture can be designed in the shape of waves or crosses to further enhance the anti-slip effect, and the surface of the anti-slip texture can be roughened to increase the coefficient of friction.

[0060] In some technical solutions, the top ends of the two water receiving plates 8 are provided with openings 7, and the top ends of the two water receiving plates 8 are equipped with connecting rods 9, which are connected to the diversion plates 6.

[0061] The opening 7 allows water droplets collected by the water receiving plate 8 to fall directly through the opening under certain conditions, preventing excessive water accumulation. The connecting rod 9 connects the water receiving plate 8 and the diversion plate 6, ensuring the stability of the structure and also helping to guide the flow path of the water droplets.

[0062] In some technical solutions, a closed door 4 is hinged at the microwave chamber of the microwave processing machine 1.

[0063] I. Work Process

[0064] Preparation stage: The operator opens the sealed door 4 of the microwave processing machine 1 and places the fermented rice and flour food on the turntable 3. Adjust the rotation speed of the turntable 3 according to the type, volume, and weight of the food to ensure even heating during processing. Close the sealed door 4 to create a closed space in the microwave chamber, providing the necessary conditions for microwave processing.

[0065] Processing Stage: Microwave processing machine 1 is started. The magnetron converts electrical energy into microwave energy at a frequency of 2450MHz. The microwaves are evenly distributed through a special structure inside the microwave chamber, heating the rice and flour food placed on the turntable 3. Driven by a motor, the turntable 3 rotates at a set speed, causing the food to rotate 360 ​​degrees within the microwave field, ensuring that all parts of the food are fully irradiated by microwaves and achieving uniform heating.

[0066] Moisture Treatment Stage: During microwave heating, the moisture in the rice and flour products evaporates into water vapor. When the water vapor rises to the top and side walls of the microwave chamber, it condenses into water droplets upon cooling. At this time, the water collection plates 8, arranged in a V-shape on the upper left and right sides of the microwave chamber, utilize their special angle and surface characteristics to intercept and guide the water droplets to both sides. Some water droplets flow along the water collection plates 8 into the liquid storage box 5; other water droplets that splash or fail to flow down in time are collected by the drainage plate 6 installed at the top of the microwave chamber. The drainage plate 6, through its slope, guides the water droplets back to the water collection plates 8, and ultimately into the liquid storage box 5. As processing continues, the liquid storage box 5 continuously collects water droplets. When the water level in the liquid storage box 5 reaches the set height of the liquid level detection device (such as a float-type liquid level sensor), the sensor sends a signal to the external control system, reminding the operator to clean the liquid storage box 5. The operator can use the sliding rail 11 and the slider 12 to pull the liquid storage box 5 out of the microwave chamber, open the sealing plug of the bottom drain port, drain the liquid in the box, and then reinstall it in its original position.

[0067] End stage: Once the rice and flour products have reached the preset processing time and temperature, the microwave processor 1 will automatically stop working. The operator will then open the closed door 4, remove the processed food, and complete one processing cycle.

[0068] II. Working Principle

[0069] Microwave heating principle: Microwaves are high-frequency electromagnetic waves, and microwaves with a frequency of 2450MHz are strongly absorbed by water molecules in food. When microwaves irradiate rice and flour products, the water molecules in the food vibrate at high speed with the microwave frequency. The molecules rub and collide with each other, generating heat energy, thus heating the food. The rotating design of the turntable 3 ensures that all parts of the food are exposed to microwaves in the microwave field, avoiding uneven heating and ensuring uniform heating of the entire food.

[0070] Moisture collection and drainage principle: The water receiving plate 8 is arranged in a "V" shape. Utilizing the principle of gravity, the condensed water droplets flow to both sides along the inclined surface of the water receiving plate 8 under their own weight. The drainage plate 6 is installed at the top of the water receiving plate 8, and its sloped surface design also utilizes gravity to guide the collected water droplets to the water receiving plate 8. The liquid storage box 5 is installed on the inner walls of both sides of the microwave chamber via a slider 12 and a slide rail 11 on the mounting platform 10, receiving the water droplets drained from the water receiving plate 8. The entire moisture collection and drainage system, through its reasonable structural design and the effect of gravity, effectively collects and treats the condensed water generated during microwave processing, preventing water droplets from falling onto the food surface and affecting processing quality.

[0071] Component Installation and Fixing Principle: The mounting plate 10 is connected to the microwave processing machine 1 via bolts. In the unique structure of the bolt body, the bolt shank 133 is screwed into the mounting screw hole and mounting screw groove, providing the main tightening force; the engagement of the circular groove 131 with the bolt shank 133 allows the bolt to adapt to certain positional and angular fine adjustments during installation. The combination of the fixing ring 136, annular pressure plate 135, spring 137, and annular rubber sheet 132, through the elastic action of the spring 137, ensures that the annular rubber sheet 132 is always under pressure, achieving a sealing and shock-absorbing effect, preventing the mounting plate 10 from loosening, while also enhancing the sealing of the connection points, avoiding external factors from affecting equipment performance, and ensuring the stability and reliability of the equipment during operation.
