Nā mea e pili ana i ka paʻa o ka meaʻai i loko o ka wai

Me ka hoʻomau mau ʻana o ka ʻoihana meaʻai i ka honua, ʻoi aku ka kiʻekiʻe o nā koi no nā mea hōʻailona o ka pellet hānai, ʻaʻole wale nā ​​​​pono o loko e pono e maikaʻi (e like me ka hana ʻai meaʻai, ka pale ʻana i nā maʻi, ka mālama ʻana i ka ʻenehana, etc.) , akā, ʻoi aku ka kiʻekiʻe o nā koi o waho (e like me ke kala, ka ʻala, ka nui a me ka lōʻihi o nā pellets hānai, ka nui o ka pohō i ka wai, etc.).Ma muli o ke ʻano o ka noho ʻana o nā holoholona aquatic, pono ka ʻai kūpono i ka paʻa wai maikaʻi e pale ai i ka lūlū wikiwiki, hoʻoheheʻe a me ka nalowale.No laila, ʻo ka paʻa ʻana o ka wai o ka meaʻai wai he mea kuhikuhi nui e hōʻoia i kona maikaʻi.ʻO nā kumu e pili ana i ka paʻa o ka meaʻai wai i loko o ka wai penei:

ʻO ka mea mua, ka nui o ka pellet o nā mea maka
ʻO ka nui o ka pellet o nā mea maka e hoʻoholo i ka ʻili o ka haku meaʻai.ʻO ka ʻoi aku ka maikaʻi o ka nui o ka pellet, ʻoi aku ka nui o ka ʻili, ʻoi aku ka ikaika o ka hiki ke komo i ka wai i ka mahu ma mua o ka granulating, kahi kūpono i ka hoʻoulu ʻana a me ka hoʻokumu ʻana i ka pellet, i mea e paʻa maikaʻi ai ka hānai pellet i ka wai, a hiki ke hoʻolōʻihi i ka manawa noho. i nā holoholona wai, hoʻomaikaʻi i ka hopena absorption, a hoʻemi i ka pollution wai.Pono nā mea hānai iʻa maʻamau e hele i 40 sieve maʻamau maʻamau ma hope o ka wili ʻana, 60 maʻiʻo sieve maʻamau maʻamau ≤20%, a hiki i nā meaʻai ʻōpae ke hele i 60 sieve maʻamau.

ʻO ka lua, make ka wili pellet
ʻO ka lākiō hoʻoemi o ke apo apo (ka hohonu o ka lua kūpono / ka nui o ka lua) he hopena kekahi i ka paʻa o ka meaʻai wai i ka wai.ʻO nā pellets hānai i hana ʻia e ke kaomi ʻana i ke apo me ka ratio hoʻopiʻi nui e ʻoi aku ka paʻakikī, ʻoi aku ka paʻa o ke ʻano a me ka manawa kūpaʻa wai.He 10-25 ka lākiō hoʻopiʻi maʻamau o ke apo wai, a he 20-35 ka hānai ʻōpae.

ʻO ke kolu, kinai a huhū
ʻO ke kumu o ka tempering ʻo: 1. Ma ka hoʻohui ʻana i ka mahu e hoʻomaʻamaʻa i ka mea, ʻoi aku ka plasticity, conducive to extrusion forming, i mea e hoʻomaikaʻi ai i ka mana pelleting o ka mīkini pelleting;2. Ma o ka hana hydrothermal, hiki ke ho'olala piha ka starch i loko o ka mea'ai, hiki ke ho'opau i ka protein, a hiki ke ho'ololi 'ia ka starch i mau carbohydrates hiki ke ho'onui i ka digestion a me ka ho'ohana 'ana o ka maunu;3. E hoʻomaikaʻi i ka nui o nā pellets, ʻano maʻalahi, ʻaʻole maʻalahi e hoʻopau ʻia e ka wai, hoʻonui i ka paʻa i ka wai;4. ʻO ka hopena wela kiʻekiʻe o ke kaʻina hana hoʻoheheʻe hiki ke pepehi i nā maʻi bacteria ʻino e like me Escherichia coli a me Salmonella i ka hānai, hoʻomaikaʻi i ka hana mālama a kūpono i ke olakino o nā holoholona wai.

ʻEhā, hoʻopili
ʻO nā adhesives nā mea hoʻohui kūikawā e pāʻani ana i ka hana o ka hoʻopaʻa ʻana a me ka hoʻokumu ʻana i ka meaʻai wai, hiki ke hoʻokaʻawale ʻia i nā mea kūlohelohe a me nā mea synthetic chemical.Hiki ke hoʻokaʻawale ʻia ka mea mua i ke kō (starch, wheat, corn meal, etc.) a me ke kāpili holoholona (bone glue, skin glue, fish pulp, etc.);He carboxymethyl cellulose, sodium polyacrylate, etc. I ke kaʻina hana o ka hana ʻai lawaiʻa, hoʻohui ʻia ka nui o ka mea hoʻopili e hoʻomaikaʻi i ka paʻa o ka meaʻai i ka wai.
