Kaʻina Hoʻomaʻemaʻe Aila Hiki: Hoʻoheheʻe wai

ʻO ke kaʻina hana degumming i ka mea kanu hoʻomaʻemaʻe aila ʻo ia ka wehe ʻana i nā haumia gum i loko o ka ʻaila maʻemaʻe ma ke ʻano kino a i ʻole kemika, a ʻo ia ka pae mua o ka hoʻomaʻemaʻe ʻaila / hoʻomaʻemaʻe.Ma hope o ke kaomi ʻana a me ka wehe ʻana i ka mea hoʻoheheʻe mai nā hua aila, ʻo ka ʻaila ʻaila ka nui o nā triglycerides a me ka liʻiliʻi ʻole triglyceride.ʻO ka hui non-triglyceride me ka phospholipids, nā protein, ka phlegmatic a me ke kō e hana me nā triglycerides e hana i ka colloid, ka mea i kapa ʻia ʻo nā haumia gum.

ʻAʻole pili wale nā ​​mea haumia i ka paʻa o ka ʻaila akā pili pū kekahi i ka hopena o ka hoʻomaʻemaʻe ʻaila a me ka hoʻoili hohonu.No ka laʻana, he mea maʻalahi ka aila non-degummed e hana i ka aila emulsified i loko o ke kaʻina hoʻomaʻemaʻe alkaline, pēlā e hoʻonui ai i ka paʻakikī o ka hana, ka hoʻomaʻemaʻe ʻaila pohō, a me ka hoʻohana ʻana i nā mea kōkua;i ke kaʻina hana decolorization, ka aila non-degummed e hoʻonui i ka hoʻohana ʻana i ka adsorbent a hoʻemi i ka pono discoloring.No laila, pono ka wehe ʻana i ke kāʻei ma ke ʻano he kaʻina mua o ka hoʻomaʻemaʻe ʻaila ma mua o ka deacidification aila, decolorization aila, a me ka deodorization aila.

ʻO nā ʻano kikoʻī o ka degumming ʻo ia ka hydrated degumming (water degumming), acid refining degumming, alkali refining method, adsorption method, electropolymerization and thermal polymerization method.Ma ke kaʻina hoʻomaʻemaʻe aila ʻai, ʻo ke ʻano maʻamau i hoʻohana ʻia ʻo ia ka hydrated degumming, hiki ke unuhi i nā phospholipids hydratable a me kekahi mau phospholipids non-hydrate, aʻo ke koena non-hydrate phospholipids pono e wehe ʻia e ka acid refining degumming.

1. Ka loina hana o ka hydrated degumming (water degumming)
Aia i loko o ka ʻaila ʻaila mai ke kaʻina hoʻoheheʻe ʻana i ka wai, ka mea nui i ka phospholipids, pono e hoʻoneʻe ʻia mai ka ʻaila e hiki ai i ka ua liʻiliʻi a hoʻopaʻa i ka wā o ka lawe ʻana i ka aila a me ka mālama lōʻihi.He ʻano hydrophilic ke ʻano o nā mea haumia e like me ka phospholipids.ʻO ka mea mua, hiki iā ʻoe ke hoʻoulu a hoʻohui i kahi nui o ka wai wela a i ʻole electrolyte aqueous solution e like me ka paʻakai & phosphoric acid i ka ʻaila ʻaila wela.Ma hope o kekahi manawa hoʻololi, e hoʻopili ʻia nā haumia gum, hoʻemi ʻia a wehe ʻia mai ka ʻaila.I ke kaʻina hana degumming hydrated, ʻo ka nui o ka phospholipid nā mea haumia, a me kekahi mau protein, glyceryl diglyceride, a me mucilage.ʻO ka mea hou aku, hiki ke hana ʻia nā ʻōpala i unuhi ʻia i lecithin no ka meaʻai, hānai holoholona a i ʻole no ka hoʻohana ʻenehana.

2. ʻO ke kaʻina hana o ka hoʻoheheʻe wai (wai degumming)
ʻO ke kaʻina hana hoʻoheheʻe wai e pili ana i ka hoʻohui ʻana i ka wai i ka ʻaila maʻemaʻe, ka hoʻomaʻemaʻe ʻana i nā ʻāpana hiki ke hoʻoheheʻe ʻia i ka wai, a laila wehe i ka hapa nui o lākou ma o ka hoʻokaʻawale centrifugal.ʻO ka māhele māmā ma hope o ka hoʻokaʻawale centrifugal ʻo ia ka ʻaila degummed crude, a ʻo ka māhele koʻikoʻi ma hope o ka hoʻokaʻawale centrifugal he hui pū ʻana o ka wai, nā mea hiki ke hoʻoheheʻe ʻia i ka wai a me ka aila i hoʻopili ʻia, i kapa ʻia ʻo "gums".Hoʻomaloʻo ʻia ka ʻaila degummed ma mua o ka hoʻouna ʻia ʻana i kahi waihona.Hoʻopi hou ʻia ka ʻāʻī ma luna o ka ʻai.

I loko o ka mea kanu hoʻomaʻemaʻe aila, hiki ke hoʻohana pū ʻia ka mīkini degumming hydrated me ka mīkini deacidification aila, ka mīkini decolorization, a me ka mīkini deodorizing, a ʻo kēia mau mīkini ke ʻano o ka laina hana hoʻomaʻemaʻe aila.Hoʻokaʻawale ʻia ka laina hoʻomaʻemaʻe i ke ʻano intermittent, semi-continuous type, a me ke ʻano hoʻomau piha.Hiki i ka mea kūʻai ke koho i ke ʻano e like me kā lākou mana hana e pono ai: ʻo ka hale hana me ka mana hana o 1-10t i kēlā me kēia lā he kūpono ia no ka hoʻohana ʻana i nā mea ʻano intermittent, 20-50t i kēlā me kēia lā hale hana kūpono no ka hoʻohana ʻana i nā mea hana semi-continuous type, e hana ana. ʻoi aku ka maikaʻi ma mua o 50t i kēlā me kēia lā no ka hoʻohana ʻana i nā lako ʻano hoʻomau.ʻO ke ʻano maʻamau i hoʻohana ʻia ʻo ia ka intermittent hydrated degumming production line.
