The invention discloses a spline curve roller type
huperzine A leaching device with a feeding
machine and a carbonizing
machine. The feeding
machine is arranged above a machine body, three stages of contra-rotating spline curve rollers are arranged in the machine body, a
huperzia serrata guide slot is arranged below each stage of the contra-rotating spline curve roller, the last stage of the guide slot is connected with a hopper of a
huperzia serrata lifting machine, a discharging slot of the lifting machine is connected with a
drying machine through a spiral
extrusion dehydration machine and a residue hopper, and the
drying machine is sequentially connected with a spiral feeding machine, a carbonizing furnace, a spiral discharging machine, a
pulverizer, a filtrate pump and a rod production machine; a liquid feeding valve is arranged on the lifting machine, a filter and a liquid outlet
pipe are arranged at the upper part of the machine body, and the liquid outlet
pipe is sequentially connected with a duplex filter, the filtrate pump and a
liquid storage tank through pipelines; a spline curve rubber disc pulse
aeration device is arranged in the machine body. Three stages of the contra-rotating spline curve rollers and the spline curve rubber disc pulse
aeration device have distinct characteristics, are capable of synergistically promoting the leaching and extraction of
huperzine A and have relatively strong practical application values.
