I-extrusion processing yesigaba sokuqala yayisetshenziswa kakhulu embonini yokucubungula ukudla.Kusukela ngeminyaka yeshumi nesishiyagalolunye nanhlanu, iMelika yayisiqale ukusebenzisa lobu buchwepheshe endaweni yokucubungula ukudla, ikakhulukazi ukucubungula ukudla kwezilwane ezifuywayo kanye nokwelashwa kwangaphambili kwezithako zokudla.
Kuze kube yiminyaka eyishumi nesishiyagalolunye, isiphenduke indlela esheshayo ethuthukayo yemboni yokucubungula ukudla emhlabeni, futhi isiqalile ukusetshenziswa emkhakheni ngamunye womkhakha wezokudla, esetshenziselwa kakhulu ukudla kwezilwane ezifuywayo okomile, ezinye izicelo zokuphakela imfuyo nokudla kwezinhlanzi.Ngokuthuthuka okungapheli kobuchwepheshe kanye nokukhuphuka okuqhubekayo kwezinga lokuphila kwabantu, ukukhula kwezilwane zasemanzini kufanele kulandele isimiso sokukhiqiza ukudla okuluhlaza ngaphandle kokungcoliswa, kuletha ukunakwa okuphawulekayo kanye nocwaningo oluningi olujulile ngobuchwepheshe bokukhiqiza ukudla kwe-aqua.Futhi kukhona ukuvumelana ukuthi ukwamukela inqubo yokukhipha inhlanzi ukuze kwenziwe ukudla kwezinhlanzi kuyindlela enkulu yokuqinisekisa ukukhiqiza imikhiqizo yasemanzini yekhwalithi ephezulu nephephile empilweni yabantu, okuphinde kube yinjwayelo yenqubekelaphambili yemboni yezokudla esikhathini esizayo.
Inqubo ye-commercial fish feed extrusion ibhekisela ekuphekeni ingxube yezithako zokudla ngaphansi kwamazinga okushisa aphezulu, umswakama kanye nokucindezela okuphezulu kusetshenziswa i-fish feed extruder ngesikhathi esifushane, lapho izinga lokushisa eliphezulu liwumphumela oqondile wokungqubuzana(i-dry extrusion) noma i-preconditioning kanye nomjovo we-steam. (i-extrusion emanzi).Njengokwelashwa kwezobuchwepheshe, i-extrusion ingenza kube nokwenzeka ukucubungula izithako ezihlukahlukene zokudla kwezinhlanzi, ezifana nobhontshisi wesoya, ummbila, ilayisi, uphizi nezinto zokusetshenziswa ezinokuqukethwe okuphezulu kwamanzi.Ngokusho kokuqukethwe komswakama wokwelashwa kwezinto zokusetshenziswa, inqubo ye-fish feed extrusion ingahlukaniswa ibe izinhlobo ezimbili - uhlobo olomile lwe-extrusion kanye ne-wet type extrusion.
Njengamanje, okokusebenza okuyinhloko kwe-extrusion esetshenziswa ekukhiqizeni ukudla kwasemanzini yi-single screw fish feed extruder ephinde ihlukaniswe yaba uhlobo olomile lwe-fish feed extruder kanye ne-wet type feed yezinhlanzi.umshini we-extruder.Ngamapharamitha ahlukene kanye nokwakhiwa kokuphakelayo, abalimi bezinhlanzi kanye nezitshalo eziphakelayo bangenza ukudla okuntantayo, okucwilayo nokucwilisa kancane okunekhwalithi ephezulu kanye nokudla okunomsoco ukuze kujwayelane nezimfuneko ezihlukahlukene zokungenisa izilwane ezihlukahlukene zasemanzini.Ukwamukela insimbi ye-alloy njengento ebonakalayo, i-FANWAY dry type fish feed extruder iye yasetshenziswa kabanzi epulazini lezinhlanzi ezincane nezisezingeni eliphakathi noma ezitshalweni eziphakelayo ukuze kukhiqizwe ukudla kwe-aqua kanye nokudla kwenja/ikati kwesilwane esifuywayo ngenxa yesakhiwo sayo esilula nomsindo ophansi.Ngaphandle kohlobo olomile, umshini omanzi wokuphakela izinhlanzi wohlobo olumanzi ufakwe kubhayela ongafaka umhwamuko njalo ekamelweni lapho ukhipha izithako zokudla, okwenza usetshenziswe kabanzi ukukhiqiza ama-pellets okuphakela kwezinhlanzi antantayo epulazini lezinhlanzi, i-aquaculture kanye namapulazi ezinkukhu.
