Isishwankathelo
Kwimveliso ye-aquafeed — ingakumbi kwiifomyula ze-shrimp ezixabisa kakhulu — i-pellet cooler ingaphezulu kakhulu kunesitya sokutshintshiselana ngobushushu. Ilawula ukulingana okubuthathaka: isusa umswakama owaneleyo ukuthintela ukungunda ngaphandle kokudala iqokobhe elibuthathaka, elomileyo kakhulu elibamba umswakama oseleyo ngaphakathi kwe-pellet core. Le nto, eyaziwa ngokuba yi-case hardening, itshabalalisa ngokuzolileyo uzinzo lwamanzi, ukuhanjiswa kwezondlo, kwaye ekugqibeleni udumo lophawu lokutya ecaleni kwechibi. Eli nqaku libhala ngokubandakanyeka kwintsimi kwindawo yokutya kwe-shrimp kuMzantsi-mpuma we-Asia apho i-Hongyang counterflow cooler, eyilwe kwaye yaqaliswa phantsi kwesakhelo se-GB/T 24351-2009, isombulule ingxaki eqhubekayo yokuqina kwe-case, yazisa inzuzo yomgangatho enokubalwa, kwaye yanciphisa amandla athile okupholisa ngaphezulu kwesithathu.
1. Ubunzima obufihlakeleyo bokupholisa ukutya okumanzi
Iipellets ezivela kwi-shrimp feed pellet mill zihlala zithwala amaqondo obushushu angama-75–95 °C kunye nokufuma komphezulu okungama-14–18%, okunyuswa yinkqubo yokulungisa i-starch ukuze ibambe kwaye ihlale iqinile. Umsebenzi wokupholisa uvakala ulula kakhulu - ukunciphisa amaqondo obushushu abe ngaphakathi kwama-3–5 °C ukusuka kwindawo engqongileyo kunye nokufuma ukuya kuma-8–10%. Kodwa ukutya okumanzi kwazisa iingxaki ezintathu ezingajongwa yi-logic eqhelekileyo yokupholisa ukutya kwemfuyo:
Okokuqala, iproteni ephezulu kunye nomxholo we-lipid. Iifomyula zokutya kwe-shrimp zihlala ziqulathe i-35-42% yeproteni ekrwada kunye ne-6-10% ye-lipid, ephuma kwi-fishmeal, i-squid meal, kunye ne-marine oils. Ezi zinto zinika ubume obunamathelayo, obufakwe iplastiki kumaqondo obushushu aphezulu. Ukuba umphezulu we-pellet uphola ngokukhawuleza kakhulu, ungena kwi-crust exineneyo, engakwazi ukungena ngaphakathi evala umswakama ngaphakathi - inkcazo yencwadi yokuqinisa icala.
Okwesibini, into ebalulekileyo yokuzinza kwamanzi. Ngokungafaniyo nokutya komhlaba, ukutya kwee-shrimp kufuneka kumelane nokubola xa kuntywiliselwa emanzini. I-pellet eneqokobhe langaphandle eliqinileyo kunye nombindi omanzi, ongapholiyo kakuhle iya kufunxa amanzi ngokungalinganiyo, idumbe, kwaye iqhekeke kwimizuzu embalwa edamini, ichithe izondlo kwaye ingcolise indawo engaphantsi komhlaba.
Okwesithathu, ukwahluka kobukhulu be-pellet. Ukutya kwe-shrimp kufikelela kububanzi ukusuka kwi-0.8 mm (i-post-larval crumble) ukuya kwi-2.5 mm (i-grower pellet), nganye inomlinganiselo owahlukileyo womphezulu ukuya kumthamo kwaye ngaloo ndlela iprofayili eyahlukileyo ye-cooling kinetics. I-cooler elungelelaniswayo nenye ayinakukwazi ukubonelela ngeziphumo ezifanayo kulo lonke olu luhlu.
Ezi zinto zichaza isizathu sokuba i-pellet cooler isoloko ikhankanywa, kwiincwadi zemfundo nakwimisebenzi yeshishini, njengeyona nto ingaphantsi kakhulu ekusebenzeni kweyunithi ekucutshungulweni kokutya emanzini.
2. I-Mill: Iprofayili kunye neMeko esele ikho

4.2 Ukufakelwa kunye nokuQaliswa
Ukufakelwa kwakhona kwisakhiwo semitshini esele sikhona kwafuna ucwangciso olucokisekileyo lwendawo. Injineli yendawo yaseHongyang idwebe indawo ekhoyo yaza yachonga ulwakhiwo olusebenzisa i-70% yemibhobho ekhoyo, yanciphisa umsebenzi wokwakha ukuya kwiziseko ezimbini zekhonkrithi kunye nokuphuculwa kwesixhobo esinye sombane. Ixesha elipheleleyo lokungasebenzi komgca wokusika yayiziiyure ezingama-52 - ngaphakathi kwesithuba seentsuku ezimbini i-mitshini eyayisibekele sona.
Ukuqaliswa komsebenzi kuqhubeke ngenkqubo ecwangcisiweyo:
1. Usuku 1: Ukuhlolwa koomatshini bokusebenza ngaphandle kokusebenzisa umoya (ukujikeleza kwefeni, ukuhamba kwesango lokukhupha umoya, ukulinganiswa kwenzwa). 2. Usuku 2: Sebenzisa amanzi ngezinto ezingasebenziyo ukuqinisekisa ingqiqo yolawulo lobunzulu bebhedi. 3.

Ukuncipha kwama-37% kwamandla okupholisa athile kuguqulelwe kwi-25,000 kWh ngonyaka ngokomthamo wemveliso yomatshini wokuphehla umbane. Kwirhafu yombane yemizi-mveliso yasekuhlaleni eyi-$0.09/kWh, oku kumele ukonga konyaka okumalunga ne-$2,250. Nangona kuncinci ngokwemigaqo epheleleyo, ukuncitshiswa kwamandla kukwaqinisekisile ukuba i-counterflow geometry yayisebenza ngokusebenza kwayo okunengqiqo - ubungqina bokuba inkqubo yayinobukhulu obuchanekileyo kwaye ilungisiwe.
6. Ingxoxo: Kutheni le nto eli tyala lithetha ngokubanzi
Olu nxibelelwano lubonisa indlela eyenzeka ngayo kwiindawo zokufunxa amanzi kwihlabathi liphela: i-cooler iphathwa njengempahla de ibe yingxaki. Isizathu esiyintloko asisoloko singumatshini ngokwawo - kukungafani phakathi kwe-cooling geometry (cross-flow) kunye ne-product physics (ii-pellets ezineproteni ephezulu, ezinobuthathaka kumswakama, ezinobubanzi obuguquguqukayo).
Ungenelelo lwaseHongyang aluphumelelanga kuba ukupholisa okuchaseneyo kuyinto entsha - lo mgaqo sele uqondwa amashumi eminyaka - kodwa ngenxa yokuba inkampani ijonge ukufakwa njengengxaki yobunjineli efuna:
1. Ukulinganisa ngaphambi kokufakela, hayi uqikelelo. Uphando lweentsuku ezintlanu luvelise idatha eyenza ukubalwa komthwalo wobushushu kube lula, kungabi yinto eqhelekileyo. 2. Ukucaca koyilo. Ukwabelana ngemodeli yokuhamba komoya kunye nesizathu sobunzulu bebhedi nabasebenzi bobuchwephesha bomatshini kwakha ukuthembana kwaye kwavumela izigqibo zokusebenza ezinolwazi emva kokunikezelwa. 3. Ukuqaliswa kwe-SKU ethile. Ukulungisa i-cooler kwi-pellet diameter nganye kwavuma inyani yokuba i-crumble eyi-0.8 mm kunye ne-pellet eyi-2.5 mm ziimveliso ezahlukeneyo ngokobushushu. 4. GB/T 24351-2009 njengomgangatho wokuthobela umthetho, hayi isilingi. Umgangatho wesizwe ubonelela ngemigangatho yokusebenza ephantsi; Ubunjineli bukaHongyang budlule kubo ngokulungelelanisa i-cooler kwindawo ethile ye-psychromemetric yesiza.
Kwifektri, imbuyekezo kutyalo-mali yanda ngaphaya kwemilinganiselo enokulinganiselwa. Ukususa ukwaliwa kokuzinza kwamanzi kubuyisele ukuthembeka kwezorhwebo ngomthengi ofuna izinto ezininzi. Ukwanda kwemveliso ngexesha lemvula - ngokwembali ixesha lemfuno ephezulu kunye nobunzima obuphezulu - kwavumela ifektri ukuba ifumane ingeniso eyayikade ishiywe ngabakhuphisana nayo ngaphambili.
7. Isiphelo
Ukupholisa ukutya kweShrimp yinkqubo enzima yobushushu ebonakala ngathi yiyunithi elula yokusebenza. Umahluko phakathi kweepellets eziqhekekayo xa zintywiliselwa emanzini kunye neepellets ezigcina ubuqotho bazo iiyure ezimbini phantsi kwamanzi udla ngokugqitywa kwimizuzu esi-8-12 ezichitha ngaphakathi kwifriji. Eli tyala libonisa ukuba indlela yobunjineli ecwangcisiweyo - umlinganiselo we-psychrometric, imodeli yobushushu ecacileyo, ukukhethwa kwezixhobo ezifanelekileyo zejometri, kunye nokufakwa kwe-SKU-level - inokusombulula ingxaki engapheliyo yomgangatho ebisoloko ixhathise iminyaka yohlengahlengiso oluqhubekayo. Xa umthengisi woomatshini ephatha i-pellet cooler njengenkqubo yobushushu eza kwakhiwa endaweni yebhokisi yentsimbi eza kuthengiswa, i-mill ayifumani nje umatshini kodwa ifumana i-asethi yemveliso ekhusela ixabiso letoni nganye ethunyelwayo.
