• Njira zina zolekanitsa zosakaniza

Pulogalamu ya anasefa, kuwunika kapena osewera ndi njira yolekanitsira magawo kusiyanitsa awiri zinthu zolimba amene particles ndi osiyana kukula kwake.

Kwa izi imagwiritsa ntchito sieve, sieve kapena chopondera, chomwe sichinangokhala china chokha kuposa netiweki yazinthu zina zosagwedezeka zomwe mipata kapena mabowo ake amalola kudutsa kwa nkhani yaying'ono kukula, kusunga m'malo mwake tinthu tating'ono tating'ono.

Ndi njira yosavuta komanso yogwiritsidwa ntchito kwambiri kupatukana zosakaniza zosakanikirana wa mankhwala olimba, zilizonse zomwe zili. Sieves amatha kukhala ndi mawonekedwe osiyanasiyana, makulidwe, ndi ma porosities.

Sieving Zitsanzo

1. Ndikusefa ufa. M'khitchini ufa umasefedwa kuti upikisidwe komanso homogenize izo, kuteteza kuti zisapangitse mabampu kamodzi osakanikirana ndi zinthu zina.
2. Kupatukana kwamchere kwamchere. Kusiyanitsa pakati mchere wa chiyambi cha mchere komanso zotsalira zamiyala kapena zinthu zina, timagwiritsa ntchito sefa yomwe imasunga zotsalira zambiri ndikulola mchere wabwino kwambiri kudutsa.
3. Kuchotsa miyala pansi. Ngati dothi louma limadutsa mu sefa, imasunga miyala ndi zinyalala zina, kulola kuti dothi loyera lidutse m'malo mwake.

5. Mukusefa mpunga. Chopondera nthawi zambiri chimagwiritsidwa ntchito kupeta mpunga kapena mbewu zina zomwe zangotulutsidwa mchikwama chawo, kuti tisiyanitse mbewu zamtengo wapatali pamiyala, zosafunika ndi mbewu zong'aluka, zomwe, pokhala zazing'ono, zimadutsa choponderacho, kusiya zomwe zimafunidwa mkati.
6. Kulekanitsa tirigu. Pakukonza ufa wa tirigu, imasefedwa m'migayo yosiyanasiyana kuti ilekanitsidwe ndi chimanga kapena mankhusu (mankhusu a njere).
7. Homogenization ya mchenga. Njirayi imachitika mgulu lazomangamanga, kuti muchepetse kukula kwa mchenga, womwe nthawi zambiri umatha kukulira muzinthu zazikulu. Imadutsa mu sefa ndipo motero chilichonse chimakhala chofanana.
8. Kuwaza m'matumba. Sinamoni, chokoleti kapena anzawo ena omwe amakhala nawo nthawi zambiri mu mitanda nthawi zambiri amapepetedwa kudzera pa chopukusira mukamawayala pamwamba pa mchere, kuti agawike mofanana komanso kuwaletsa kuti asasiye zotsalira zazikulu.
9. Kompositi. Njira yobwezeretsanso zinthu zachilengedwe nthawi zambiri imapindula ndi kuwunika kosavuta, kuti mutenge kuchokera kusakanikirana komwe kumabwezeretsanso panthaka pulasitiki, zachitsulo kapena tinthu tating'onoting'ono tomwe tingaipitse. Zinthu zakuthupi ndizopepuka kotero kuti zimadutsa mu sefa, pomwe zinthu zolimba zimatsalira.
10. Ogwedeza mchere ndi tsabola. Chivundikiro cha zida izi, chomwe chimapangidwira, chimagwira ngati sefa, kusunga zinthu zambiri (mchere kapena tsabola) mkati mwa chidebecho, komanso zotumphukira zomwe zidapangidwa (ena ogwedeza mchere amaikanso mpunga mkati), kapena kungochepetsa kuchepa kwake kupita pachakudya.

1. Sefa mu Migodi. Kuti mupeze golide ndi miyala ina yamtengo wapatali, mitundu ina ya sefa imagwiritsidwa ntchito kupatula mchere wamtengo wapatali pamchenga kapena nthaka, yomwe nthawi zambiri idakonzedwa kale.
2. Kupanga khofi. Pofuna kusiyanitsa tirigu ndi zotsalira za masamba, timitengo kapena zinthu zina zomwe zimatsagana ndi mabulosi a khofi pomwe akugwiritsa ntchito, amagwiritsa ntchito sefa.
3. Kukonza bokosi lazinyalala za paka. Amachita pogwiritsa ntchito sefa yoboola pakati, yomwe imalola kuti mchengawo udutse koma umasunga ndowe za nyama.
4. Kuwona simenti. Popeza ndi chinthu cha desiccant, simenti imakonda kusonkhanitsa chinyezi kuchokera m'chilengedwe, ndikupanga zotupa zazing'ono ngati miyala. Ndiye kuti imasefa musanaigwiritse ntchito pakupanga chisakanizo cha zomangamanga.
5. Kupatukana kwa mbewu. M'makampani opanga mbewu, njere nthawi zambiri zimafufuzidwa kuti zizisiyanitse ndi zosafunika zomwe zimawonjezedwa pokonza ndi nyama zomwe zimangodya.
