Mbewu zosungidwa zikatha kukolola, kaya zosungidwa m’nkhokwe ya dziko kapena m’nyumba za alimi, ngati sizinasungidwe bwino, zidzakhudzidwa ndi tizirombo tosungidwa. Alimi ena awonongeka kwambiri chifukwa cha kuwononga tizilombo tosungidwa, tizilombo towononga pafupifupi 300 pa kilogalamu imodzi ya tirigu ndi kuchepa kwa 10% kapena kuposerapo.

Biology ya tizirombo tosungira ndikukwawa nthawi zonse mu mulu wa tirigu. Kodi pali njira yothanirana ndi tizilombo tosungidwa m'zakudya popanda kugwiritsa ntchito mankhwala opha tizilombo omwe amakhudza chilengedwe komanso thanzi la anthu? Inde, ndi diatomite, mankhwala achilengedwe omwe amagwiritsidwa ntchito posungira tizilombo towononga mbewu. Diatomite ndi gawo la geological lopangidwa kuchokera ku mafupa opangidwa kuchokera ku mafupa ambiri a m'madzi ndi m'madzi opanda mchere, makamaka ma diatoms ndi algae. Ma depositi awa ali ndi zaka zosachepera 2 miliyoni. Ufa wa Diatomite wamtundu wabwino ukhoza kupezeka mwa kukumba, kuphwanya ndi kugaya. Monga mankhwala ophera tizilombo, ufa wa diatomite umatha kuyamwa bwino ndipo umakhala ndi chiyembekezo chogwiritsa ntchito pothana ndi tizirombo tosungidwa. Diatomite ili ndi zinthu zambiri zachilengedwe, zopanda poizoni, zopanda fungo komanso zosavuta kugwiritsa ntchito. Choncho, akulimbikitsidwa kuti azigwiritsidwa ntchito kumidzi kuti apange njira yatsopano yowonongera tizilombo tosungidwa m'madera akumidzi. Kuphatikiza pa mayamwidwe abwino, kukula kwa tinthu, kufanana, mawonekedwe, pH mtengo, mawonekedwe a mlingo ndi chiyero cha diatomite ndizofunikira zomwe zimakhudza mphamvu yake yowononga tizilombo. Diatomite ndi zotsatira zabwino tizilombo ayenera koyera amorphous pakachitsulo ndi tinthu awiri <. 10μm(micron),pH <8.5, ili ndi dongo laling'ono komanso losakwana 1% crystalline silicon.

Zinthu zosiyanasiyana zomwe zimakhudza ufa wa diatomite kuti zithetse tizirombo ta tirigu zosungidwa zinaphunziridwa ku United States: mawonekedwe a mlingo, mlingo, mitundu yoyesera tizilombo, njira yolumikizirana pakati pa tizirombo ndi diatomite, nthawi yolumikizana, mitundu yosiyanasiyana ya tirigu, boma la tirigu (mbewu yonse, tirigu wosweka, ufa), kutentha ndi madzi a tirigu, etc.

Chifukwa chiyani diatomite imatha kupha tizirombo tosungidwa?

Izi ndichifukwa choti ufa wa diatomite uli ndi mphamvu zotha kuyamwa ma esters. Thupi la njere - kusunga tizirombo lili ndi malo okhwima komanso ma bristles ambiri. Ufa wa diatomite umapaka pathupi la tizilombo tosungidwa pamene tikukwawa m'njere zomwe zakonzedwa. Mbali yakunja ya khoma la thupi la tizilombo imatchedwa epidermis. Mu epidermis pali phula woonda kwambiri, ndipo kunja kwa phula pali sera woonda wokhala ndi esters. Ngakhale kuti phula ndi phula loteteza ndi lopyapyala kwambiri, zimagwira ntchito yofunika kwambiri posunga madzi mkati mwa thupi la tizilombo, lomwe ndi "chotchinga madzi" cha tizilombo. Mwa kuyankhula kwina, "chotchinga madzi" chikhoza kulepheretsa madzi omwe ali mkati mwa tizilombo toyambitsa matenda kuti asasunthike ndikuwapangitsa kukhala ndi moyo. Diatomite ufa ukhoza kuyamwa mwamphamvu esters ndi sera, kuwononga "chotchinga madzi" cha tizirombo, kuwapangitsa kutaya madzi, kuchepa thupi ndipo pamapeto pake kufa.
