I STET electrostatic ngokwahlukana inqubo yome ngokuphelele, ezidinga kungekho amanzi noma amakhemikhali. Dry izindlela ngokwahlukana electrostatic akunika ithuba ukukhiqiza imikhiqizo emisha futhi functional ngaphezulu isitshalo amaprotheni, including sunflower seed meal with increased protein content for use as a high value animal feed. This protein enriched sunflower seed meal can be used as a non-GMO replacement for soy meal, and add value to sunflower oil crushing operators and feed producers.
A sample of solvent extracted sunflower seed meal was purchased by STET for pilot testing. The sunflower meal was finely milled (ezomile) zibe osayizi bezinhlayiyana ezimbili, a coarser feed with a d50 = 70 Micron, prepared with a hammer mill and a finer feed with a d50 = 25 Micron, kulungiswe ngomshini wokugaya umoya. The dry sunflower seed meal samples were then separated using the STET tribo-electrostatic belt separator. Subsamples of the negatively charged and positively charged products were measured for protein using the DUMAS method.
Finely milled dry sunflower seed meal samples demonstrated excellent sunflower protein separation. Okwe-coarser (d50 = 70 Micron) isampula, the feed sample containing approximately 39% amaprotheni (isisekelo ezomile) was separated into a product containing 52% amaprotheni kanye nomkhiqizo one-a 29% amaprotheni, endaweni eyodwa ngokusebenzisa isihlukanisi. Okwabangcono (d50 = 25 Micron) isampula, umkhiqizo one-a 54% protein content was generated, with a by-product with 25% amaprotheni, endaweni eyodwa ngokusebenzisa isihlukanisi.
The tribo-electrostatic belt separator demonstrated the capability to process finely ground sunflower seed meal to significantly upgrade the protein content, okwenza kube esiwusizo nakakhulu kokudla kwezilwane. The STET tribo-electric belt separator offers many benefits for processing sunflower meal including continuous operation, high okuphakelayo izinga afika ku 15 amathani angu okuphakelayo, ongaphakeme energy ukusetshenziswa, kalula zokusebenzela kanye okusezingeni eliphezulu nokwethenjelwa mechanical.
