The invention discloses a contra-rotating roller type huperzine-A infusion and extraction device with a feeder and a
charcoal molding machine. A feeder is arranged on a device body, the internal of the device body is provided with three-stage contra-rotating rollers, the lower of each stage of the contra-rotating roller is respectively provided with a serrate clubmoss
herb guide groove, the last stage of the guide groove is connected with a hopper of a serrate clubmoss
herb hoist, a discharging groove of the hoist is connected with a drier through a spiral extruding dehydrator and a residue hopper, and the drier is sequentially connected with a spiral feeding
machine, a
charcoal furnace, a spiral discharging
machine, a
crusher and a rod making
machine; the hoist is provided with a liquid
inlet valve, the upper part of the device body is provided with a filter and a liquid outlet
pipe, and the liquid outlet
pipe is sequentially connected with a duplex filter, a filtrate pump and a
liquid storage tank through a pipeline; the internal of the device body is provided with a spline curve rubber plate pulse detonating device, and a mechanical
ultrasonic vibration exciter is arranged at the lower left corner of the device body. The three-stage contra-rotating spline curve rollers, the spline curve rubber plate pulse detonating device and the mechanical
ultrasonic vibration exciter provided by the invention all have distinct characteristics, which can synergistically promote the infusion and extraction of the huperzine-A, and have relatively strong practical application value.
