Title:
SPIRAL SCATTERING AND CYCLONE GRADING-BASED PEANUT SHELL ULTRAFINE POWDER GRADING AND PACKAGING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/208163
Kind Code:
A1
Abstract:
A spiral scattering and cyclone grading-based peanut shell ultrafine powder grading and packaging system and method, relating to the technical field of peanut processing. The system comprises a scattering device, a grading device, and a packaging device. The grading device comprises a grading cavity. The grading cavity comprises a cylindrical part (II-03) and a conical part (II-04) on the lower side of the cylindrical part (II-03). An air inlet feed port (II-01) and an air inlet (II-02) are symmetrically and tangentially arranged in the middle of the cylindrical part (II-03). A cylindrical screen grading cavity (II-0604) coaxial with the cylindrical part (II-03) is provided in the cylindrical part (II-03). A grading impeller (II-0701) coaxial with the cylindrical part (II-03) is provided in the screen grading cavity (II-0604). Scattered ultrafine powder is subjected to primary grading by means of swirling airflow formed by the air inlet feed port (II-01) and the air inlet (II-02), a screen (II-0601) works in conjunction with the swirling airflow to perform secondary grading on the ultrafine powder having a particle size greater than the aperture of the screen (II-0601), and the grading impeller (II-0701) works in conjunction with high-speed swirling airflow to perform tertiary grading on the ultrafine powder. The system solves the problems of difficulty in ultrafine powder grading size control, low grading precision, low packaging efficiency, and poor compaction effect, thereby greatly improving the scattering, grading and packaging efficiency of peanut shell ultrafine powder.
