Chifukwa cha mitundu yosiyanasiyana ya ziwiya za labotale, makamaka kapangidwe kowonda komanso kakatali ka machubu akuluakulu oyesera, zimabweretsa zovuta zina pantchito yoyeretsa. Makina oyeretsera machubu oyesera okha omwe kampani yathu idapanga amatha kuyeretsa ndikuumitsa mkati ndi kunja kwa machubu oyesera m'mbali zonse. Ndi oyenera kwambiri kuyeretsa machubu oyesera mu Kjeldahl nitrogen deteminators.
1) Kupopera kwa chitoliro choyimirira cha chitsulo chosapanga dzimbiri cha 304, kuyenda kwa madzi amphamvu komanso kuyeretsa kwa kugunda kwa mtima kwakukulu kungatsimikizire ukhondo woyeretsa.
2) Makina otenthetsera mpweya oumitsira mpweya okhala ndi mphamvu yamphamvu komanso mpweya waukulu amatha kumaliza ntchito youmitsira mofulumira, ndi kutentha kwakukulu kwa 80℃.
3) Kuonjezera madzi oyeretsera okha.
4) Thanki yamadzi yomangidwa mkati, kubwezeretsanso madzi odziyimira pawokha komanso kuyimitsa yokha.
5) Kuyeretsa kokhazikika: ① Kuthira madzi bwino → ② Kuthira thovu loyeretsera → ③ Lowetsani → ④ Kutsuka ndi madzi bwino → ⑤ Kuumitsa ndi mpweya wotentha kwambiri.
6) Kuyeretsa mozama: ① Kutsuka ndi madzi → ② Kupopera thovu loyeretsera → ③ Kulowetsedwa → ④ Kutsuka ndi madzi → ⑤ Kupopera thovu loyeretsera → ⑥ Kulowetsedwa → ⑦ Kutsuka ndi madzi → ⑧ Kuwumitsa ndi mpweya wotentha kwambiri.
