(1) Te whakatau i te matotoru: Ka whakaritea te hua maroke ki roto i tētahi otinga wai me te taumaha kukū o te 2°C, ā, ka inehia mā te mita matotoru hurihuri NDJ-1;
(2) He paura te āhua o te hua, ā, ko te hua tonu kua tāpirihia ki te "s".
Me pēhea te whakamahi i te hydroxypropyl methylcellulose
Tāpirihia tika i te wā whakaputa, ko tēnei tikanga te tikanga māmā rawa atu, ā, ko te tikanga poto rawa atu hoki, ko ngā mahi motuhake ko:
1. Tāpirihia he nui o te wai kohua ki roto i tētahi oko kua whakaohokia me te ahotea kutikuti teitei (ka wairewa ngā hua hydroxyethyl cellulose ki te wai matao, nō reira tāpirihia he wai matao);
2. Whakakāhia te whakaoho i te tere puhoi, ka tātari mārire i te hua ki roto i te ipu whakaoho;
3. Me whakaoho tonu kia mākū katoa ngā matūriki;
4. Tāpirihia he nui o te wai matao, ka whakaoho tonu kia memeha rawa ngā kai katoa (ka tino piki ake te mārama o te otinga);
5. Kātahi ka tāpirihia ētahi atu kai ki te tauira.
Te whakarite i te wai whaea mō te whakamahinga: Ko tēnei tikanga he hanga i te hua hei wai whaea he nui ake te kukū i te tuatahi, kātahi ka tāpirihia ki te hua. Ko te painga he nui ake te ngāwari, ā, ka taea te tāpiri tika ki te hua kua oti. He rite tonu ngā mahi ki ngā mahi (1-3) i roto i te tikanga tāpiri tika. Kia mākū rawa te hua, waiho kia tū kia memeha noa te whakamatao, kātahi ka whakaohokia i mua i te whakamahinga. Me mōhio me tāpiri wawe tonu te rongoā harore ki te wai whaea.
Ranunga maroke: I muri i te whakaranu maroke i te paura me ngā rauemi paura (pērā i te sima, te paura gypsum, te uku uku, me ētahi atu), tāpirihia he nui o te wai e tika ana, pokepokea, ka whakaoho kia memeha rawa te hua.
Te whakarewanga o ngā hua wairewa matao: ka taea te tāpiri tika i ngā hua wairewa matao ki te wai matao hei whakarewa. I muri i te tāpiri i te wai matao, ka tere te totohu o te hua. I muri i te mākū mō tētahi wā, tīmata te whakaoho kia memeha rawa.
Ngā whakatūpato i te wā e whakarite ana i ngā otinga
(1) Kaua ngā hua kāore he maimoatanga mata (haunga te hydroxyethyl cellulose) e whakarewa tika ki te wai matao;
(2) Me āta tātari ki roto i te ipu whakaranu, kaua e tāpirihia he nui, he hua rānei kua hanga hei poraka ki roto i te ipu whakaranu;
(3) He mārama te hononga o te pāmahana wai me te uara pH o te wai ki te memeha o te hua, nō reira me aro nui atu;
(4) Kaua e tāpirihia ētahi matū kawakore ki te ranunga i mua i te whakamākūkūtanga o te paura hua ki te wai, ā, kaua e whakanuia te uara ph i muri i te whakamākūkūtanga, ka āwhina i te memeha;
(5) Ki te taea, tāpirihia he rongoā harore i mua i te wā;
(6) Ina whakamahia ngā hua matotoru, kaua te taumaha o te wai whaea e neke ake i te 2.5-3%, ki te kore ka uaua te whakahaere i te wai whaea;
(7) Kaua ngā hua kua rewa tonutia e whakamahia ki ngā hua kai, ki ngā hua rongoā rānei.
