DETAILED DESCRIPTION

[0021] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, in this embodiment, a high-efficiency plasma agricultural product processing device is provided, which is mainly composed of a vacuum chamber 13, a feeding device 8, a discharging device 1, a spiral conveyor belt 14 and other components. Both ends of the vacuum chamber 13 are provided with a head 5 to ensure the sealing of the vacuum chamber 13, and a double-layer tempered glass window is also provided at the head 5 to facilitate workers to observe the internal processing conditions or fault problems.

[0023] Among them, the feeding device 8 is installed at the upper end of the vacuum cavity 13, and the lower end of the feeding device 8 is connected to the vacuum cavity 13. A flow valve is also provided at the connection point, and the flow valve is provided with a flow regulating knob 7 to control the flow rate of the feed. A sealing cover 9 is installed at the top entrance of the feeding device 8. The sealing cover 9 can be opened to add agricultural products into the feeding device 8. After it is full, the sealing cover 9 is covered and sealed. After the vacuum cavity 13 is adjusted to a suitable vacuum level, the flow valve is opened to feed the material. The flow rate of the falling material can be controlled by the flow regulating knob 7. In addition, the discharging device 1 is installed at the lower end of the vacuum cavity 13, and the upper end of the discharging device 1 is connected to the vacuum cavity 13, which is used for the short-term material receiving and discharging work before discharging. A valve can be provided at the lower end of the discharging device 1 to open and close the discharging. When the agricultural products in the discharging device 1 are full, the valve can be opened to discharge the whole material, which is efficient and fast.

[0024] In order to achieve efficient sterilization and pest control, a spiral conveyor belt 14 is arranged inside the vacuum chamber 13. The starting point of the spiral conveyor belt 14 is located below the lower port of the feeding device 8, which is suitable for receiving materials, and the end point of the spiral conveyor belt 14 is located above the discharging device 1, which is suitable for unloading materials. At the same time, a plasma discharge mechanism is arranged on each circle of the spiral conveyor belt 14, and each plasma discharge mechanism specifically comprises a pair of discharge electrode plates 11 and a shielding layer 12 covering the discharge electrode plates 11. The pair of discharge electrode plates 11 are respectively arranged on the upper and lower sides of the same position of the spiral conveyor belt 14, and of course there is also a radio frequency power supply system 2. The radio frequency power supply system 2 can be arranged outside the vacuum chamber 13, which is electrically connected to the discharge electrode plates 11 and is used to power the discharge electrode plates 11 for plasma discharge, thereby effectively killing microorganisms and pests in agricultural products and improving the quality and safety of agricultural products.

[0025] Specifically, the spiral conveyor belt 14 in this embodiment can be driven by the driving motor 6, and the spiral angle and number of turns of the spiral conveyor belt 14 can be selected according to the type of agricultural products to be processed. At the same time, a rubber layer is also provided on the conveyor belt surface of the spiral conveyor belt 14 to prevent the material from slipping and falling, enhance the surface friction, and avoid damage to the material.

[0026] Through the above design, it can be seen that this embodiment uses the spiral conveyor belt 14 as a mechanism for transmitting agricultural product materials in the vacuum chamber 13, and a plasma discharge mechanism is set on each circle of the spiral conveyor belt 14 to perform sterilization and pest control, so that the agricultural products can be sterilized and pest controlled multiple times during the transmission process from the feed port to the discharge port, saving the processing time of the same amount of agricultural product materials, effectively improving the processing efficiency and quality, and meeting the needs of large-scale and efficient agricultural product processing.

[0027] In addition, in order to improve the quality of treatment, an air extraction device 3 and an exhaust device 4 for adjusting the vacuum degree are arranged outside the vacuum chamber 13 of the present embodiment. The air extraction device 3 and the exhaust device 4 can select existing equipment such as an air extraction pump and an exhaust pump. The air extraction device 3 can extract the gas in the vacuum chamber 13, and the exhaust device 4 can blow air into the vacuum chamber 13. The two can cooperate to adjust the vacuum degree in the vacuum chamber 13 to provide a suitable treatment environment and improve the sterilization and pest control quality of agricultural products. Of course, a connecting pipe 10 can be added to the side wall of the feeding device 8, which is connected to the inside of the vacuum chamber 13 through the connecting pipe 10, so that the inside of the feeding device 8 and the inside of the vacuum chamber 13 can maintain the same vacuum effect.

[0028] At the same time, on the basis of ensuring processing efficiency, this embodiment adopts a spiral conveyor belt 14 as a mechanism for transmitting agricultural product materials, which can effectively reduce the lateral space occupied by the equipment, reduce the size and floor space of the overall equipment, and reduce the manufacturing cost of the equipment; and the structural design is simple, and the agricultural product materials can be processed while being transmitted, which makes the processing more convenient and simple.
