He mīhini tukatuka tēnei e whakamahia whānuitia ana mō te hanga i ngā matū totoka i roto i te umanga rongoā. Ko āna mahi ko te whakaranu, te whakapūkara, me ētahi atu. Kua whakamahia whānuitia i roto i ngā umanga pēnei i te rongoā, te kai, te matū, me ētahi atu.

He mea hanga ki te maitai kore waikura austenitic kounga teitei, he pewa te whakawhiti o ngā kokonga katoa, kāore he pito mate, kāore he toenga, kāore he mata kōpiko me te mata pūkohu, ā, he tīwiri kitea.
He tino oro te mata o roto, o waho hoki. Ka eke te taratara o roto ki te Ra≤0.2μm. Ka pania te mata o waho ki te paninga matte, ā, ka eke te taratara ki te Ra≤0.4μm, he ngāwari ki te horoi.
Mā te pūnaha whakahaere PLC, ka taea te whakaoti aunoa i te mahi kia rite ki ngā hiahia o te kaiwhakamahi mā te whakatakoto i ngā tawhā tukanga. Ka taea te tā aunoa i ngā tawhā tukanga katoa, ā, he pono, he pono hoki ngā tuhinga taketake.

Whakatutuki i ngā whakaritenga GMP mō te hanga rongoā.
