Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

FIG. 1 is a schematic structural diagram of a starch extraction device, and the device mainly comprises a first-stage crusher 101, a first stirring conveyor 107, a first filter press 110, a second-stage crusher 201, a second stirring conveyor 207, a second filter press 210, an ultrasonic generator 300 and a centrifugal precipitator 400; the discharge port of the first-stage pulverizer 101 is connected to the feed port of the first mixing conveyor 107, the first mixing conveyor 107 is provided with a first water inlet 102 at one end of the feed port, a rotating shaft with a spiral plate is arranged in the middle of the first mixing conveyor 107, the rotating shaft extends out of the barrel from one side of the feed port, the end part of the rotating shaft is provided with a first sealing device 103 for keeping water seal, and a first driving motor 104 is connected to the rotating shaft of the first mixing conveyor 107 through a transmission part for driving the rotating shaft to rotate. The pretreated sweet potatoes are put into a first-stage pulverizer 101 through an inlet for pulverization, the pulverized sweet potatoes are sent into a first stirring conveyor 107, meanwhile, clear water is sent into the first water inlet 102, a rotating shaft rotates to bring the pulverized sweet potatoes to be conveyed at the outlet side, and the pulverized sweet potatoes are continuously stirred and mixed with the input clear water fully under the action of a spiral piece in the conveying process; the ground sweet potato powder mixing machine is characterized in that a first filter press 110 is fed from a discharge port 108 of a first stirring conveyor 107 after sufficient mixing, input ground sweet potatoes are extruded through a first driving piston 105, mixed water containing a large amount of starch is extruded out and discharged through a liquid outlet 106 of the first filter press, in order to prevent residues from being mixed into final products, a filter screen is arranged on the liquid outlet 106 of the first filter press according to the size of the sweet potato starch, and the aperture of the filter screen is 100-150 meshes.

The residue after being extruded by the first filter press actually contains a large amount of starch, and the existing equipment is directly discarded or directly used for other applications, so that the waste is large. In order to further separate out the starch contained in the starch, the economic value is improved. The sweet potatoes after the first cleaning and extrusion are sent into a second-stage crusher through a slag discharge port 109 of a first filter press to be crushed again, the crushed sweet potatoes are sent into a second stirring conveyor 207, the middle of the second stirring conveyor 207 is provided with a rotating shaft with a spiral sheet, the rotating shaft extends out of the cylinder from one side of a material inlet, the end part of the rotating shaft is provided with a second sealing device 203 for keeping water seal, and a second driving motor 204 is connected with the rotating shaft of the second stirring conveyor 207 through a transmission part to drive the rotating shaft to rotate; clear water is fed in through the second water inlet 202, the rotating shaft rotates to bring the crushed sweet potato phase outlet side for conveying, and the crushed sweet potato phase outlet side is continuously stirred and mixed with the input clear water under the action of the spiral piece in the conveying process; after being sufficiently mixed, the mixture is sent into a second filter press 210 from a discharge port 208 of a second stirring conveyor 207; because the starch contained in the second filter press is greatly reduced compared with the starch contained in the second filter press originally, the residual starch is combined with other residues more secretly, the ultrasonic generator 300 is arranged on the bottom surface of the second filter press, the ultrasonic generator is started to generate ultrasonic waves before extrusion, the ultrasonic waves are transmitted to the mixture of the sweet potatoes and the water in the second filter press through the bottom surface of the second filter press, and the separation effect of the starch and the residues is greatly improved and the starch content in the water is improved through ultrasonic vibration.
