• Fokotsa ho hlaha ha mafu: Thempereichara e phahameng, mongobo o phahameng le khatello e phahameng nakong ea ho ruruha ho ka bolaea likokoana-hloko tse kotsi ka ho fetisisa, ho thusa ho boloka boleng ba metsi le ho fokotsa maemo a mabe a tikoloho aquaculture, ha ho ntse ho fokotsa ho shoa ha liphoofolo tse phelang metsing.
• Eketsa boima ba ho ikatisa: Tšebeliso ea phepelo ea motsoako oa extruded e ka fokotsa coefficient ea phepelo 'me ea fokotsa haholo palo ea masala le mantle a ntšetsoang ka metsing, e leng se etsang hore ho khonehe ho eketsa boholo ba ho ikatisa.
• Eketsa nako ea ho boloka phepelo: Ho eketsa le ho phuphura ho ntlafatsa botsitso ba thepa e tala ka ho fokotsa bongata ba baktheria le oxidation.
• Eketsa tatso le tshilo ya dijo: Phepelo e atolositsweng e fetoha sebopeho se hlephileng le se sa hlakang. Phetoho ena e fana ka sebaka se seholo sa ho kopana bakeng sa li-enzyme, tse loketseng ho kopana le liketane tsa starch, liketane tsa peptide le li-enzyme tsa tšilo ea lijo, 'me li thusa ho sila lijo. ho monya, ka hona ho ntlafatsa tšilo ea lijo.
• Ntlafatsa ho qhibiliha ha fiber: Ho ntša le ho phuphutsa ho ka fokotsa haholo fiber e se nang mafura ka har'a phepelo le ho ntlafatsa tšebeliso ea phepelo.
Mathata a extruder granulation:
• Ho senyeha ha livithamine: Ho hohlana pakeng tsa khatello, mocheso, mongobo tikolohong le lijong ho ka lebisa tahlehelong ea livithamine tse jeoang, haholo-holo vithamine A, vithamine D le folic acid.
• Thibelo ea litokisetso tsa enzyme: Lithempereichara tse phahameng nakong ea ho ruruha li ka 'na tsa lahleheloa ke butle-butle le ka ho feletseng mosebetsi oa litokisetso tsa enzyme.
• Senya li-amino acid le liprotheine: Tlas'a maemo a mocheso o phahameng, ho ikhohomosa ho tla baka maikutlo a Maillard pakeng tsa ho fokotsa tsoekere e teng lihlahisoa le li-amino acid tse sa lefelloeng, ho fokotsa tšebeliso ea liprotheine tse ling.
• Litšenyehelo tse phahameng tsa tlhahiso: Mokhoa oa ho atolosa phepelo o rarahane ho feta mokhoa o akaretsang oa phepelo ea pellet. Thepa ea ts'ebetso ea ho atolosa e theko e boima, e na le matla a phahameng a matla, 'me e na le tlhahiso e tlaase, e bakang litšenyehelo tse phahameng.
Melemo ea mochini oa granulating:
• Ts'ebetso e phahameng ea tlhahiso: Granulator e ka potlakela ho fetola lihlahisoa tse tala lihlahisoa tsa granular tsa sebopeho se hlokahalang, ho ntlafatsa katleho ea tlhahiso.
• Boholo ba likaroloana tse sa tšoaneng: Nakong ea ts'ebetso ea granulation, thepa e tlas'a matla a ho kuta le matla a extrusion, ho etsa hore ho ajoa ha likaroloana tsa likaroloana tse phethiloeng.
• Ts'ebetso e bonolo: Granulator e na le mohaho o bonolo, o bonolo ho o sebetsa, 'me o bonolo ho o laola le ho o fetola.
• Sebaka se pharaletseng sa ts'ebeliso: Granulator e ka sebelisoa bakeng sa granulating ea mefuta e fapaneng ea lisebelisoa, ho kenyelletsa le meriana ea granular, lisebelisoa tse tala tsa lik'hemik'hale, lijo, joalo-joalo.
Mathata a granulator ea granulation:
• Tšenyo e ka bang teng ea livithamine le litokisetso tsa enzyme: Mocheso o phahameng le khatello nakong ea granulation li ka senya mosebetsi oa livithamine le litokisetso tsa enzyme.
• Tšenyo e ka bang teng ho li-amino acid le liprotheine: Tlas'a maemo a mocheso o phahameng, granulation e ka baka maikutlo a Maillard pakeng tsa ho fokotseha ha tsoekere ea lihlahisoa le li-amino acid tse sa lefelloeng, ho fokotsa tšebeliso ea liprotheine tse ling.
• Thepa e nang le granulated e omme ebile e metsi: lebelo la ho kopanya le nako ea ho kopanya ea granulator kapa lebelo la ho kuta le nako ea ho kuta ea ho kuta li tlaase haholo ho qhala se tlamang kapa se kolobisang ka potlako le ka ho lekana. Ho tla ba le ho kopanya ho sa tšoaneng le granulation ea thepa.
• Likokoana-hloko li etsa li-agglomerates le agglomerate: Palo ea li-binder e kentsoeng kapa e kenyang metsi e phahame haholo 'me sekhahla sa ho eketsa se potlakile. Ho kgothaletswa ho fokotsa ka nepo palo ya se tlamella kapa ho koloba le ho laola sekgahla sa tlatsetso.
Ka kakaretso, granulation ea extruder le granulator e 'ngoe le e' ngoe e na le melemo le mathata a eona a ikhethang, 'me khetho e hloka ho khethoa ho latela litlhoko le maemo a itseng a kopo.
