Ka hoʻohana ʻana i nā lako hana ʻuala

ʻO nā lako hana ʻuala ʻuala ʻuala piha piha piha i ka ʻuala ʻuala, a ʻo ke kaʻina hana o nā lako hana ʻuala ʻuala:

ʻuala → (mea hoʻomaʻemaʻe hoʻomaʻemaʻe) → hoʻomaʻemaʻe (mea hoʻomaʻemaʻe hoʻomaʻemaʻe) → ʻokiʻoki (mea holoi a ʻōpala faila) → hoʻokaʻawale ʻana i ka pulp a me ke koena (ke kaomi curved sieve a centrifugal sieve, pulp a me ke koena separation garden sieve) → wehe i ke one (sand remover) → ka hoʻokaʻawale ʻana i ka fiber protein (mea hoʻokaʻawale disk, ʻāpana ʻino) → dehydration (centrifuge a i ʻole vacuum dehydrator).

Hiki i ke koho ʻana i nā mea hana ʻuala ʻuala ke koho i nā lako hana ʻuala me nā ʻano hoʻonohonoho like ʻole mai nā ʻano o ke ʻano o ka hana starch, ka hiki ke hana ʻana i nā mea hana, nā lako lako, ka hoʻonohonoho ʻana o ka starch i hoʻopau ʻia, a me nā mea ʻē aʻe, i hui pū me kāna pono ponoʻī. Ma ka ʻāpana ʻokiʻoki, ua hoʻolālā kūikawā nā mea ʻenekini Kaifeng Sida i kahi mea wili ʻuala kiʻekiʻe kiʻekiʻe, kahi e hoʻohana ai i ke kaʻina hana pālua o ka "cutter + crusher + grinder". ʻOi aku ka kiʻekiʻe o ka coefficient grinding material, ʻoi aku ka kiʻekiʻe o ka 95%, a ʻoi aku ka kiʻekiʻe o ka hōʻiliʻili starch.

Aia kekahi ʻano starch i kūpono i ka hapa nui o ka poʻe mahiʻai i ka starch hana ponoʻī. ʻO ka maʻamau, ʻaʻole nui ka hoʻopuka, a ʻoi aku ka maʻalahi o ke kaʻina hana. ʻO ka laina hana maʻalahi ka hoʻomaʻemaʻe-crushing-filtration-sand removal-sedimentation tank-drying.

He ʻiʻo keʻokeʻo ka ʻuala kiʻekiʻe a me ka ʻuala kiʻekiʻe, ka pākēneka kiʻekiʻe o nā ʻuala nui, a me ka nui o ka starch ma kahi o 24%-26%. Hiki i ka hua kiʻekiʻe o kēlā me kēia mea kanu ke piʻi ma mua o 50 kg. Ua hoʻohana nui ʻia nā huahana e like me ke kō, ka glucose anhydrous, oligosaccharides, sorbose a me ka ʻuala ʻuala, me nā pōmaikaʻi waiwai nui a me nā manaʻo o ka mākeke. Hōʻike nui ʻia ma nā ʻano aʻe:

1. Ka hana ʻana o ka ʻuala i hoʻomaʻemaʻe ʻia

ʻIke ʻia ka maikaʻi o ke kumukūʻai o ka ʻuala i hoʻomaʻemaʻe ʻia i ka ʻuala o koʻu ʻāina i ka hoʻokūkū honua. I kēlā me kēia makahiki, lawe mai ʻo South Korea i ka ʻuala i hoʻomaʻemaʻe ʻia mai Kina a ʻo ka vermicelli i hana ʻia me ka starch i hoʻomaʻemaʻe ʻia a hiki i ka 50,000 tons; Nui, ʻoi aku ma mua o 1 miliona mau mea e pono ai i kēlā me kēia makahiki. I kēia manawa, ʻoi aku ka nui o ka starch i hoʻomaʻemaʻe ʻia ma Kina ma mua o 300,000 tons. No laila, aia kahi mākeke kūloko nui.

2. Ka hana ʻana i ka mākiko uala i hoʻololi ʻia

ʻO ka starch hoʻololi ʻia he ʻano starch i hoʻohana nui ʻia ma o ka hoʻololi ʻana i kona ʻano starch a me nā waiwai ma o ka lāʻau kino, kemika a enzymatic paha. Hoʻohana nui ʻia i ka meaʻai, pepa, textile, petroleum a me nā ʻoihana ʻē aʻe.

3. Ka hana ʻana i ka meaʻai ʻuala a me ka mākiko olakino a me kāna mau huahana.

Ua neʻe mālie nā manaʻo meaʻai o nā kānaka mai ka meaʻai a me nā lole i ka meaʻai a me ka mālama olakino, a mai kahi hana hoʻokahi o ka meaʻai i nā ʻano hana like ʻole. No ka laʻana, hiki i ka hoʻohui ʻana i nā wai huaʻai hou a me nā wai huaʻai o nā waihoʻoluʻu like ʻole i ka mākiko ʻuala maʻamau e hiki ke hana i ka vermicelli momona momona, ka ʻili pauka meaʻai kala, a pēlā aku; Hiki ke hana ʻia nā lāʻau lapaʻau kuʻuna Kina e mālama i ke olakino e like me ka ʻuala i ʻili pauda mālama olakino me nā hana like ʻole.

4. Iecaianoaaiiuo omaomao paʻa mea, etc.

Ke hoʻohana nei i ka starch ʻuala ma ke ʻano he kumu kumu, hiki ke hana ʻia i loko o ka decomposed piha, non-toxic green packaging material a me nā kiʻiʻoniʻoni mahiʻai, me ka hoʻohana ʻana i ka ʻenehana hoʻoheheʻe starch e hana i nā waiwai ʻili hoʻopau, hiki ke hana ʻia i mea momona a hānai ʻia ma hope o ka hana hou ʻana. a hydrolyzed loa i loko o 60 mau lā ma hope o ka hoʻolei ʻia ʻana. No laila, he ʻoihana hoʻohiki kēia i kākoʻo ʻia e ka mālama ʻana i ke kaiapuni e hoʻopau i ka "pollu keʻokeʻo".
