Description

Technical Field

[0001] This utility model relates to the field of microwave sterilization technology, specifically to microwave sterilization equipment. Background Technology

[0002] In many industries such as food, medicine, and cosmetics, product sterilization is crucial. Traditional sterilization methods mainly include heat sterilization and chemical sterilization. Microwave sterilization utilizes the interaction between microwaves and molecules to generate heat through molecular vibration and friction, thereby achieving rapid temperature rise and sterilization. It has advantages such as fast sterilization speed, high efficiency, and better preservation of product nutrients, flavor, and color. Moreover, it does not require chemical reagents, is energy-saving and environmentally friendly. In modern industrial production, it has gradually become a highly promising and competitive sterilization technology, widely used in the processing and manufacturing of various products to meet the needs of high-quality product production.

[0003] Traditional sterilization methods mainly include thermal sterilization and microwave sterilization. Thermal sterilization can effectively kill most microorganisms through high temperature and long time. However, for heat-resistant spores, it often requires high temperature and long time, which can easily lead to a decline in product quality, such as loss of nutrients, changes in flavor, and deterioration in texture. Microwave sterilization uses the interaction between microwaves and the molecules of matter to generate heat for sterilization. It has the characteristics of fast heating speed and high efficiency. However, when using microwave sterilization alone, the inactivation effect on heat-resistant spores is limited, and it is difficult to completely remove them. This makes it difficult to efficiently remove heat-resistant spores while ensuring product quality.

[0004] Therefore, this utility model provides a microwave sterilization device to solve the above problems. Utility Model Content

The inner side of the steam pipe has multiple air outlets for gas discharge, and a closed mesh to prevent material from falling is fixedly connected inside the air outlets, so that the material inside the steam pipe can be heated and sterilized by the steam pumps. A sterilization mechanism is provided above the steam mechanism.

[0008] The sterilization mechanism includes a sterilization chamber for sterilization, and the sterilization chamber is equipped with a microwave generator for sterilization. A discharge port two is fixedly connected to the side of the sterilization chamber so that the material is discharged from the discharge port two after sterilization.

[0009] Preferably, a support plate for supporting the extrusion tube is fixedly connected to the equipment bracket, and the end of the equipment bracket is fixedly connected to the steam mechanism through a fixing frame. The two steam pumps are respectively fixedly connected to both ends of the fixing frame.

Detailed Implementation

[0022] 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.

[0023] Example 1:

[0024] Please see Figures 1 to 4The microwave sterilization equipment includes a support frame 1, a motor 4, an extrusion tube 5 and two steam pumps 6. The extrusion tube 5 is rotatably connected to an extrusion screw 10 for conveying materials, and the extrusion screw 10 is fixedly connected to the output shaft of the motor 4 via a coupling. The end of the extrusion tube 5 is provided with a steam mechanism 8 for steam sterilization.

[0025] The steam mechanism 8 includes a steam pipe 81 fixed to the end of the extrusion pipe 5. The steam pipe 81 has an air passage 82 for gas flow inside. Two steam pumps 6 are connected to the air passage 82 through an air inlet pipe 84. The inner side of the steam pipe 81 has multiple air outlets 83 for gas discharge. The air outlets 83 are fixedly connected to a closed net to prevent material from falling, so that the material inside the steam pipe 81 can be heated and sterilized by the steam pumps 6. A sterilization mechanism 7 is provided above the steam mechanism 8.

[0026] The sterilization mechanism 7 includes a sterilization chamber 71 for sterilization, and a microwave generator for sterilization is installed inside the sterilization chamber 71. A discharge port 2 9 is fixedly connected to the side of the sterilization chamber 71 so that the material is discharged from the discharge port 2 9 after sterilization. When the material reaches the end of the extrusion tube 5 and enters the steam pipe 81, the two steam pumps 6 work synchronously. The steam pumps 6 draw water through the water inlet pipe and convert it into steam. The steam enters the air passage 82 of the steam pipe 81 through the air inlet pipe 84, and is then evenly sprayed into the steam pipe 81 from multiple air outlets 83, making full contact with the material to achieve steam sterilization. The closed mesh inside the air outlet 83 can prevent the material from falling under the steam impact.

[0027] Example 2:

[0028] Please see Figures 1 to 4This embodiment provides a technical solution based on embodiment one: a support plate 2 for supporting the extrusion tube 5 is fixedly connected to the equipment bracket 1, and the end of the equipment bracket 1 is fixedly connected to the steam mechanism 8 through the fixing frame 3. Two steam pumps 6 are respectively fixedly connected to both ends of the fixing frame 3. A water inlet pipe is connected to one side of the steam pump 6, and one end of the water inlet pipe passes through and extends into the interior of the steam pump 6. One end of the extrusion screw 10 passes through and extends into the interior of the extrusion tube 5. A collection box is provided below the discharge port 2 9 to collect the sterilized material. A support leg is fixedly connected to the bottom of the equipment bracket 1, and an anti-slip pad is fixedly connected to the bottom of the support leg. A protective cover is fixedly connected to the top of the fixing frame 3, and the motor 4 is located inside the protective cover. The sterilization mechanism 7 also includes four rotating shafts 73 fixed to both ends of the sterilization box 71. Two rotating shafts 73 are fixedly connected to rotating rods 74. Both ends of the two rotating rods 74 are fixedly connected to a flipping plate 75 for flipping the blown material, and both ends of the rotating rods 74 are fixedly connected to a drive plate for rotating the material. The fan 76, which rotates the rod 74, causes the rod 74 to rotate when the steam rises. Both sides of the sterilization chamber 71 have discharge ports 72 for discharging the blown material. A sealed bearing to prevent material leakage is installed at the connection between the rotating shaft 73 and the sterilization chamber 71. The surface of the tilting plate 75 is provided with guide grooves for material flow and tilting. The material sterilized by steam enters the sterilization chamber 71, where a microwave generator produces microwaves that interact with the polar molecules in the material, causing molecular vibration and friction. Heat further sterilizes the materials. In the sterilization chamber 71, rising steam drives the impeller 76 to rotate. The impeller 76 is fixedly connected to the rotating rod 74, thereby driving the rotating rod 74 to rotate. The flipping plates 75 at both ends of the rotating rod 74 flip the smaller materials blown up by the steam and discharge them through the discharge ports 72 on both sides of the sterilization chamber 71, avoiding excessive microwave sterilization of these smaller materials. The larger materials remain in the sterilization chamber 71 and, after sterilization under microwave action, are discharged from the discharge port 9 and fall into the collection box.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: During operation, motor 4 first starts running after being energized. Its output shaft transmits power to extrusion screw 10 through a coupling, causing extrusion screw 10 to rotate inside extrusion tube 5. Material is continuously introduced from the feed end of extrusion tube 5 and moves steadily towards the end of extrusion tube 5 under the spiral propulsion of extrusion screw 10. When the material reaches the end of extrusion tube 5 and smoothly enters steam pipe 81, two steam pumps 6 start synchronously. Steam pumps 6 draw water through water inlet pipe, and after internal heating and vaporization processes, the water is converted into high-temperature steam. This steam enters the air passage 82 inside steam pipe 81 through air inlet pipe 84, and then passes through the air passage... Multiple air outlets 83 on the steam chamber 82 evenly and continuously spray steam into the steam pipe 81. The material comes into full contact with the high-temperature steam in the steam pipe 81, and the heat carried by the steam is rapidly transferred to the material, thus achieving steam sterilization. A sealed mesh is fixedly connected inside the air outlets 83 to prevent the material from falling out under the impact of the steam. Simultaneously, the microwave generator inside the sterilization chamber 71 starts working, generating microwaves of a specific frequency. The microwaves interact with polar molecules such as water molecules in the material, causing molecular vibration and friction, thereby generating heat and rapidly raising the temperature of the material. Utilizing the high heat and penetrating power of the steam, heat-resistant buds can be destroyed. The structure and physiological function of the spores render them inactive. The microwaves generated by the microwave generator in the sterilization mechanism 7 penetrate deep into the material, interacting with the molecules within the heat-resistant spores to generate heat, further enhancing the killing effect. Inside the sterilization chamber 71, steam rises due to its own upward movement. During this process, the steam blows up some smaller, finer particles. At this point, the flipping plates 75 at both ends of the rotating rod 74 in the sterilization mechanism 7 begin to function. As the rising steam drives the impeller 76 to rotate, and the impeller 76 is fixedly connected to the rotating rod 74, the rotating rod 74 also rotates. When the rotating rod 74 rotates, the flipping plates 75 at both ends... The rotating plate 75 will flip over. The purpose of the rotating plate 75 is to guide smaller materials to the discharge ports 72 on both sides of the sterilization chamber 71 after they are blown up by steam. This prevents the smaller materials from staying in the sterilization chamber 71 for a long time and being over-sterilized due to excessive microwave radiation. The larger materials that are not blown up by steam will remain in the sterilization chamber 71 and complete the sterilization process under the continuous action of microwaves. Finally, they will be discharged from the discharge port 9 on the side of the sterilization chamber 71 and fall into the collection box that is set below the discharge port 9.
