Description

Technical Field

[0001] This application relates to the field of microwave drying and sterilization machines, and in particular to an integrated microwave drying and sterilization machine for bamboo fungus powder. Background Technology

[0002] Microwave drying and sterilization machines are industrial equipment that utilize 2450MHz microwave electromagnetic field technology to achieve efficient dehydration and sterilization. Through the dual effects of generating heat through high-speed friction of water molecules and destroying the cell structure of microorganisms, drying and sterilization can be completed quickly at low temperatures of 50-150℃. Compared with traditional methods, it saves more than 50% on energy and provides uniform processing. It is particularly suitable for processing heat-sensitive materials such as food and Chinese medicinal materials. Its core components include a magnetron, a waveguide system, and a PLC control module. Microwave drying and sterilization machines are often used for processing bamboo fungus powder. In conventional microwave drying and sterilization machines, the material to be processed is placed on top of a conveyor rack. A microwave generator and a heating furnace are fixedly connected to the top of the conveyor rack. The microwave generator converts electrical energy into microwave energy through the magnetron, which is then transmitted to the heating furnace through the waveguide. The heating furnace retains the generated heat, thereby drying and sterilizing the material.

[0003] Regarding the aforementioned technologies, the inventors believe that during the processing of conventional bamboo fungus powder, due to the varying sizes and shapes of the bamboo fungus, some areas are difficult to dry and sterilize during the drying and sterilization process, thus affecting the processing effect of the bamboo fungus.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0017] This application discloses a microwave drying and sterilization integrated machine for bamboo fungus powder, referring to... Figure 1 - Figure 2 The system includes a transmission rack 1. When processing bamboo fungus powder, the material is placed on top of the transmission rack 1. A microwave generator 2 and a heating furnace 3 are fixedly connected to the top of the transmission rack 1. The microwave generator 2 converts electrical energy into microwave energy through a magnetron and transmits it to the heating furnace 3 through a waveguide. The heating furnace 3 retains the generated heat, thereby drying and sterilizing the material. A connecting box 4 is installed between the microwave generator 2 and the heating furnace 3. An extrusion cylinder 5 is rotatably connected to the inner wall of the connecting box 4. Several shielding nets 6 are fixedly installed on the inner wall of the extrusion cylinder 5 to prevent the material from entering the extrusion cylinder 5. The extrusion cylinder 5 flattens the bamboo fungus material on top of the transmission rack 1, thereby improving the drying and sterilization effect of the microwave dryer and avoiding the problem of poor drying effect caused by the uneven shape of the bamboo fungus.

[0018] Reference Figure 2A support frame 7 is fixedly installed on the surface of the connecting box 4. A motor 8 is fixedly connected to the top of the support frame 7. The output end of the motor 8 is fixedly installed to one end of the extrusion cylinder 5. After the motor 8 is started, it controls the rotation of the extrusion cylinder 5, thereby reducing the amount of manual operation. A nylon separation brush 9 is slidably connected to the surface of the extrusion roller. The nylon material of the separation brush 9 has high heat resistance to prevent the separation brush 9 from being damaged by high temperature. The separation brush 9 is installed on the surface of the heating furnace 3 by means of the slide rail 10. The separation brush 9 removes the processing material adhering to the surface of the extrusion roller, thereby preventing the processing material from rotating with the extrusion roller. A fixing frame 11 is fixedly connected to one end of the separation brush 9. Two connecting bolts 12 are snapped into the inner wall of the fixing frame 11. The surface of the connecting bolts 12 is threaded to the inner wall of the slide rail 10. The connecting bolts 12 make it easy to connect the fixing frame 11 to the slide rail 10. After the connecting bolts 12 are removed, it is easy to separate the separation brush 9 from the slide rail 10, so that the separation brush 9 can be replaced regularly to prevent wear of the separation brush 9 from affecting the cleaning effect.

[0019] Reference Figure 3 - Figure 4 A cover 13 is installed on the top of the connecting box 4. Two handles 14 are fixedly connected to the top of the cover 13.

A support frame 7 is fixedly installed on the surface of the connecting box 4, and a motor 8 is fixedly connected to the top of the support frame 7. The output end of the motor 8 is fixedly installed to one end of the extrusion cylinder 5 so that the extrusion cylinder 5 can be controlled to rotate after the motor 8 is started, thereby reducing the need for manual labor. The working volume is such that a separation brush 9 is slidably connected to the surface of the extrusion roller. The separation brush 9 is mounted on the surface of the heating furnace 3 via a slide rail 10, so as to remove the processing material adhering to the surface of the extrusion roller with the separation brush 9, thereby preventing the processing material from rotating with the extrusion roller. One end of the separation brush 9 is fixedly connected to a fixing frame 11. Two connecting bolts 12 are snapped into the inner wall of the fixing frame 11. The surface of the connecting bolts 12 is threaded to the inner wall of the slide rail 10, so as to facilitate the connection between the fixing frame 11 and the slide rail 10 with the connecting bolts 12. After the connecting bolts 12 are removed, the separation brush 9 can be easily separated from the slide rail 10, so as to replace the separation brush 9 regularly and prevent the separation brush 9 from being worn and affecting the cleaning effect.

[0021] A cover 13 can also be installed on the top of the connecting box 4. Two handles 14 are fixedly connected to the top of the cover 13 to cover the top of the connecting box 4. The handles 14 can be used to open the cover 13 to facilitate cleaning of the extrusion cylinder 5. A fixing bolt 15 is snapped into the inside of the cover 13.
