Kukonzekera kwa kuphika kwakukulu ndi mpweya, ufa wofiira bwino umagwiritsidwa ntchito. Idzaza ndi oxygen, yopangidwa popanda mitsempha komanso yogwirizana. Pachifukwa ichi, mthunzi wa mugweti wopeta ufa ukhoza kukhala mthandizi wabwino kwa mbuye aliyense.
Mfundo yofunikira ya mug-sieve
Mfundo ya makina-sieve ya makina ndi yotsatira. Chipangizocho chili ndiwiri kapena katatu pansi. Mmenemo muli chiwindi chapadera, pamene chimangoyendetsedwa, chimangoyendayenda chimayendetsedwa, kupyola mu sieve ufa kapena mankhwala ena omwe ayenera kuponyedwa. Pa nthawi yomweyi, palibe galamu imodzi ya mankhwala yomwe imapangidwira pamwamba pa tebulo ndi kuzungulira.
Ubwino wa Mugulu wa Sieve
Mutayamba kugwiritsa ntchito mphika wa sieve, mudzawona kuti uli ndi ubwino wambiri poyerekezera ndi msomali wowoneka wozungulira, womwe ndi:
- zosavuta kugwira;
- mwayi wogwiritsira ntchito mitundu yambiri ya mankhwala: ufa, wowuma, shuga wothira, kakale, nyengo;
- chokhazikika;
- sieving poyerekeza kwambiri ndi sieve yeniyeni (kapangidwe kamakhala ndi ma sieves awiri kapena atatu);
- compact, amatengera pang'ono malo mu kabati iliyonse khitchini;
- Kugwiritsa ntchito ndalama zochuluka zogulitsa zinthu, popeza sizikutsanulira pamphepete.
Mitundu ya ma sieves a mugga
Malingana ndi zomwe anapanga, zikho za sieve zingakhale za mitundu yotsatirayi:
- sieve yopangidwa ndi chitsulo chosapanga dzimbiri;
- pulasitiki mug sieve. Mugupe wotero ukhoza kukhala ndi sieve yachitsulo.
Choncho, pogula mkaka wa sieve, mumathandiza kwambiri kupanga zokoma ndi zokoma. Kuphatikiza apo, mungathe kumasula mosavuta zinthu zomwe mukufunikira popanda kugwiritsa ntchito khama kwambiri.
