Msika woumitsira mpunga udzawonanso zochitika zatsopano

Chidule:

Kapangidwe ka zida zochepetsera tirigu wonyowa kwambiri kufika pa miyezo yachitetezo nthawi imodzi kumafuna kuchepetsa ndi 10%. Pachifukwa ichi, pali njira ziwiri: imodzi ndikugwiritsa ntchito njira yowumitsa yolumikizirana, kutanthauza, njira zoposa ziwiri zowumitsa zosakanikirana mu njira yatsopano yowumitsa, monga chowumitsa cha rapid fluidization chotentha kwambiri kuti chipange chotenthetsera tirigu wonyowa, kenako chowumitsa chozungulira pa kutentha kochepa kuti chiwume. Kuchokera pakukula kwa ukadaulo wowumitsa mpunga padziko lonse lapansi…

Anthu ambiri ku China amakonda kudya mpunga, ndipo mpunga umathandizanso kwambiri ulimi wa tirigu ku China. Ndi kusintha kwa zida zaulimi, zinthu zambiri zokhudza ulimi wa mpunga zasinthidwa kukhala makina. Chifukwa cha mvula ndi malo okhala ndi mitambo komanso chinyezi, chowumitsira mpunga chamtsogolo chidzakhalanso ndi gawo lofunika kwambiri pakukolola mpunga, ndipo msika wa chowumitsira mpunga udzawonekeranso zatsopano.

Kuumitsa mpunga ndi gawo lofunika kwambiri pakukolola tirigu. Chifukwa kukolola kuti kuchepetse kutayika kwa munda ndikofunika kulabadira kukolola kwa nthawi yake, komanso kukolola tirigu pa nthawi yake, chinyezi chake chimakhala chachikulu, monga kuumitsa kwa nthawi yake kudzayambitsa nkhungu ndi kuwonongeka kwa tirigu. Kuumitsa mpunga kooneka ndi vuto lomwe silinganyalanyazidwe.

Pa zida zoumitsira tirigu ku China, pamodzi ndi zomwe anthu ambiri akumidzi akufuna, chitukuko cha zida zoumitsira tirigu m'nyumba chidzawonetsa izi:
(1) mphamvu yopangira makina owumitsa mpunga iyenera kukhala yayikulu, mtsogolomo pakufunika kukulitsa mphamvu yopangira matani 20-30 pa ola limodzi la zida.
(2) Kupanga zida zochepetsera tirigu wonyowa kwambiri kufika pamlingo wotetezeka nthawi imodzi kumafuna kuchepetsa ndi 10%. Pachifukwa ichi, pali njira ziwiri: imodzi ndikugwiritsa ntchito njira yowumitsira yolumikizirana, kutanthauza njira zoposa ziwiri zowumitsira zosakanikirana kukhala njira yatsopano yowumitsira, monga chowumitsira chachangu cha kutentha kwambiri kuti chipange tirigu wonyowa, kenako chowumitsira chozungulira pa kutentha kochepa kuti chiwumitse. Kuchokera pakukula kwa ukadaulo wowumitsira mpunga padziko lonse lapansi, iyi ndi njira yodziwika bwino. Yachiwiri ndi kapangidwe ka chowumitsira mpunga chogwira ntchito bwino kwambiri.
(3) Kugwiritsa ntchito ukadaulo woyezera ndi kuwongolera kuti njira yowumitsa igwire ntchito yokha kapena njira yodziyimira yokha.
(4) Chidebe chotenthetsera kwambiri komanso chokonzedwa mwachangu cha mpunga wambiri wonyowa kwambiri.
(5) Kafukufuku wokhudza malasha ngati gwero la mphamvu, chowumitsira mpunga chosagwiritsa ntchito mphamvu mwachindunji ndiye njira yayikulu, komanso ayenera kufufuza chowumitsira mpunga chatsopano, monga mphamvu ya microwave, mphamvu ya dzuwa ndi zina zotero.
(6) Choumitsira mpunga chakumidzi chiyenera kukhala chaching'ono, chogwira ntchito zosiyanasiyana, chofunikira kuti chizisunthika mosavuta, chizigwiritsidwa ntchito mosavuta, ndalama zochepa ndipo chingatsimikizire ubwino wa kuumitsa mpunga.
