Ngophuhliso oluqhubekayo loshishino lwezondlo kwihlabathi, iimfuno zezalathi ze-pellet yokutya zisanda phezulu, ayisiyiyo kuphela iimfuno zangaphakathi zomgangatho kufuneka zibe zilungile (ezifana nokusebenza kwesondlo, ukuthintela izifo, ukukhuselwa kokusingqongileyo kwimizi-mveliso, njl. , kodwa kunye neemfuno zomgangatho wangaphandle zinyuka kakhulu (ezifana nombala, iphunga, ubungakanani kunye nomlinganiselo wobude beepelisi zokutya, izinga lokulahleka emanzini, njl.).Ngenxa yobume bendawo ephilayo yezilwanyana zasemanzini, ukutya okuhambelanayo kufuna uzinzo oluhle lwamanzi ukuthintela ukusasazeka okukhawulezayo, ukonakala kunye nelahleko.Ngoko ke, ukuzinza kwamanzi okutya kwamanzi kuyisalathisi esibalulekileyo sokuqinisekisa umgangatho walo.Izinto ezichaphazela uzinzo lokutya kwamanzi emanzini zezi zilandelayo:
Okokuqala, ubukhulu bepellet yemathiriyeli ekrwada
Ubungakanani bepellet yezinto eziluhlaza bumisela indawo ephezulu yokwakheka kwesondlo.Okukhona ubungakanani bepellet bucolekile, kokukhona umkhulu indawo yomphezulu, kokukhona ukomelela amandla okufunxa ukufuma kumphunga phambi kokuba igranulating, nto leyo enceda ubushushu kunye nokwenza iipellet, ukuze ukutya kwepellet kube nokuzinza okuhle emanzini, kwaye nako kunokwandisa ixesha lokuhlala. kwimfuyo yasemanzini, ukuphucula umphumo wokufunxa, kunye nokunciphisa ukungcoliseka kwamanzi.Isondlo sentlanzi ngokubanzi kufuneka sidlule kwisihluzo esiqhelekileyo esijoliswe kuma-40 emva kokusila, umxholo we-sieve ojoliswe kuyo ongama-60 ≤20%, kunye nempahla ekrwada ye-shrimp inokudlula i-60 ye-sieve ekujoliswe kuyo.
Okwesibini, ilitye lokusila liyafa
Umlinganiselo wokunyanzeliswa komngundo wendandatho (ubunzulu obusebenzayo bomngxuma / ubungakanani bomngxuma) nawo unempembelelo ethile kuzinzo lokutya kwamanzi emanzini.Iipelisi zokutya eziveliswe ngokucinezela i-mold mold kunye ne-compression ratio enkulu iya kuba nobunzima obuphezulu, isakhiwo esiqinileyo kunye nexesha elide lokumelana namanzi.Umlinganiselo wokunyanzeliswa oqhelekileyo wokufa kwendandatho yamanzi ngu-10-25, kwaye i-shrimp feed yi-20-35.
Okwesithathu, kuhluthwe kwaye kunomsindo
Injongo yokufudumala kukuba: 1. Ngokudibanisa i-steam ukuthambisa izinto eziphathekayo, iplastiki eninzi, iququzelele ukubunjwa kwe-extrusion, ukwenzela ukuba kuphuculwe umthamo we-pelleting yomatshini wokugaya;2. Ngokusebenzisa i-hydrothermal action, isitashi kwi-feed inokuthi ifakwe i-gelatinized ngokupheleleyo, iprotheyini inokuthi ifakwe i-denatured, kwaye isitashi sinokuguqulwa sibe yi-carbohydrates e-soluble ukuze kuphuculwe ukugaya kunye nokusetyenziswa kwe-bait;3. Ukuphucula ubuninzi beepellets, ukubonakala okugudileyo, akulula ukuchithwa ngamanzi, ukwandisa ukuzinza emanzini;4. Ukushisa okuphezulu kwefuthe lenkqubo yokufudumala kunokubulala iibhaktheriya ezinobungozi ezifana ne-Escherichia coli kunye ne-Salmonella kwisondlo, ukuphucula ukusebenza kokugcina kwaye kuhambelana nempilo yemfuyo yasemanzini.
Isine, incamathelisa
I-Adhesives izongezo ezikhethekileyo ezidlala indima yokudibanisa kunye nokwenza kwisondlo sasemanzini, esinokuthi sahlulwe ngokufanelekileyo kwizinto zendalo kunye nezinto ezenziwe ngemichiza.I-yangaphambili inokwahlulwa ibe yiswekile (isitashi, ingqolowa, ingqolowa yokutya, njl.) kunye neglue yezilwanyana (i-bone glue, iglue yesikhumba, i-pulp yentlanzi, njl.);Izinto ezenziwe ngemichiza yi-carboxymethyl cellulose, i-sodium polyacrylate, njl.
