The working principle is as follows: pouring pea protein powder into the feeding barrel 12, starting the first motor 13, driving the packing auger 14 to rotate by the first motor 13, pushing the pea protein powder to the inside of the cylindrical barrel 2 when the packing auger 14 rotates, when the pea protein powder falls from the first filter screen 15 to the inside of the cylinder 2, the fan 18 blows the pea protein powder into the connecting pipe 4, and the wind blown by the fan 18 carries the heat heated by the heating rod 19, so that the wind blown by the fan 18 has the temperature, the pea protein powder can be primarily dried, the pea protein powder with larger particles can fall into the conical filter screen 20, the auger 14 can drive the first rotating shaft 24 to rotate in the rotating process, thereby make first axis of rotation 24 drive second axis of rotation 25 and rotate, drive abrasive plate 26 when second axis of rotation 25 rotates for abrasive plate 26 grinds the pea protein powder of big granule.
Can be blown by the wind that fan 18 blown when the pea protein powder up to standard after the grinding drops downwards for pea protein powder after the grinding blows to connecting pipe 4 inside, when pea protein powder blows to connecting pipe 4 inside, air-blower 3 inhales the air-supply line 5 with the pea protein powder at 2 tops of cylinder section of thick bamboo in 4 connecting pipes, discharge in 7 to trapezoidal collecting box from going out tuber pipe 6 again, at this in-process, wind can drive pea protein powder and flow together, when wind drove pea protein powder through annular heating plate 35, annular heating plate 35 dries pea protein powder once more.
When wind drives pea protein powder to flow from the air outlet pipe 6 to the air guide pipe 11 and passes through the conical pipe 10, the wind speed is increased due to the area reduction, the increased wind speed can blow the turnover plate 31, so that the turnover plate 31 drives the third rotating shaft 30 to rotate, when wind blows from the gap 29 to the interior of the trapezoidal collection box 7, the wind speed is smaller due to the area increase, after the wind drives the pea protein powder to blow to the interior of the trapezoidal collection box 7, the pea protein powder falls to the bottom of the trapezoidal collection box 7 under the weight of gravity and is collected from the discharge bin 8, when other part of the pea protein powder is blown to the third filter screen 34 by the wind, the third filter screen 34 filters the pea protein powder, so that clean wind is discharged from the air outlet pipe 33 to the outside, and part of the pea protein powder is attached to the third filter screen 34, however, the third rotating shaft 30 drives the scraper 32 to rotate, so that scraper 32 scrapes off pea protein powder on third filter 34.
Exemplary embodiments of the proposed solution of the present disclosure have been described in detail above with reference to preferred embodiments, however, it will be understood by those skilled in the art that many variations and modifications may be made to the specific embodiments described above, and that many combinations of the various technical features and structures presented in the present disclosure may be made without departing from the concept of the present disclosure, without departing from the scope of the present disclosure, which is defined by the appended claims.
