The box side panel 28 and the receiving plate 7 are simultaneously opened, and the bottom belt driving wheel 29 drives the bottom belt 30 in the storage and conveying box 5 to start rotating clockwise, and the material stirring roller 27 simultaneously acts to stir the materials to the belt in the discharging conveyor 11. After the material discharging is finished, the material stirring roller 27 stops, the box side panel 28 and the receiving plate 7 are closed, the motion control system controls the lifting motor 15 to rotate forward, the empty box after the material discharging is lifted to the feeding box position, and controls the transverse moving motor 20 to rotate forward, and the next storage conveying box 5 to be discharged is transversely moved to the discharging box position.
The control valve 10 is adjusted to a position for closing the feeding and discharging belt 13, the discharging conveyor 11 conveys tobacco materials to the inlet of the climbing conveyor 12, and the climbing conveyor 13 conveys the materials to the feeder 2 for returning circulation. When the total fermentation time of the materials reaches 72 hours, the control valve 10 is adjusted to the fully open position, the discharging conveyor 11 conveys the tobacco materials to the feeding and discharging belt 13, and the next procedure is carried out.
The warm and humid air enters from four air inlets 8 on the side surface of the fermentation chamber 1, flows out from two air return inlets 9 on the top of the fermentation chamber 1, and is continuously recycled through an air inlet pipeline, the fermentation chamber 1 and an air return pipeline after treatment. The temperature and humidity wind should meet the requirements of temperature, humidity and oxygen content of tobacco fermentation.
It should be noted that, the left, right, upper, lower, etc. azimuth or positional relationships defined in the present invention are based on the azimuth or positional relationships shown in the drawings, and are merely for convenience of description of the present device and simplification of description, and are not indicative or implying that the device or element to be referred must have a specific azimuth, be configured and operated in a specific azimuth, and thus should not be construed as limiting the present invention.
