Nkhani ya Msika: Kufunika kwa Madzi ku Ayeyarwady Delta
Dera la Ayeyarwady Delta, lomwe lili pafupi ndi mzinda wa Pathein, ndi likulu la ulimi wa nkhanu zakuda za tiger (Penaeus monodon) ku Myanmar. Deta ya boma yofalitsidwa ndi Xinhua mu Julayi 2024 inatsimikizira kuti dziko la Myanmar likufuna kutulutsa ana aang'ono oposa 40 miliyoni mu FY 2024-25, ndipo kupanga ana aang'ono pachaka kupitirira 100 miliyoni; ndalamazo zimathandizira dziwe lamalonda losungiramo nsomba m'madera a delta, Taninthayi ndi Yangon. Kumbali yotumiza kunja, bungwe la Taninthayi Region Fisheries Federation linanena kuti matani 5,946 a nkhanu za Panamei (Pacific white) adatumizidwa kunja pofika Disembala m'chaka chachuma cha 2024-25, ndipo zidutswa zouma zotumizidwa ku Japan ndi zinthu zophikidwa ku China, ndipo dzikolo likugwira ntchito mwakhama kuti liwonjezere kupanga madzi amchere kupitirira nyengo yamvula.
Polimbana ndi kukula kumeneku, kuchuluka kwa chakudya cha m'madzi m'deralo kwachepa. Kufalikira kwa mafakitale ndi eFeedLink kumapeto kwa chaka cha 2009 kunanena kale kuti mafakitale 26 odyetsera nsomba ali ku Yangon, Pathein, Mandalay ndi mizinda ina yochepa, koma patatha zaka khumi gawo la chakudya cha nkhanu limaperekedwabe kwambiri ndi ma pellets ochokera ku Thailand ndi Vietnam. Kusiyana kumeneku kumawonekera kwambiri m'mphepete mwa dziwe: chakudya chochokera kunja chimafuna ndalama zambiri, chimafika nthawi yosagwirizana, ndipo nthawi zambiri chimagwa mu PDI ndi kukhazikika kwa madzi chidebecho chikakhala panjira kwa milungu ingapo. Kwa delta integrator yomwe yafotokozedwa pankhaniyi, kusinthasintha kumeneko kunali chifukwa chobweretsa ma pellets m'nyumba.
Kasitomala: Gulu la Famu ya Nkhwangwa Yophatikiza Patsogolo
Kasitomalayu ndi gulu la aquaculture lomwe limayang'anira mabanja omwe akhala akugwiritsa ntchito maiwe a black tiger shrimp okwana mahekitala 120 kuzungulira tawuni ya Pathein kwa zaka zoposa khumi ndi zisanu. Mwiniwake ndi mlimi wa m'badwo wachiwiri; amagulitsa zokolola zake zambiri kwa wogulitsa nsomba ku Yangon ndipo amagwira ntchito ndi alimi ena ang'onoang'ono okwana mahekitala 40 pansi pa mgwirizano wopezera chakudya ndi zokolola. Kumayambiriro kwa chaka cha 2025, pambuyo pa maulendo awiri otsatizana pomwe shrimp crumble yochokera kunja idataya zoposa 8% ya kuchuluka kwake chifukwa cha kusweka panthawi yoyenda kuchokera ku Yangon kupita ku Pathein, gululo linaganiza zokhazikitsa mzere wawo wopezera chakudya cha shrimp, womwe unkakwanira maiwe awo komanso kupereka ndalama ku minda yapafupi.
Pempho loyambirira la zofunikira, lomwe linaperekedwa kwa ogulitsa angapo aku China ndi ku Europe, linali la mzere wamadzi wa 2 T/H. Magawo a khalidwe losakambirana anali: pellet durability index (PDI, Holmen 30 s) opitilira 95% pa die ya 1.8 mm; kukhazikika kwa madzi opitilira maola atatu m'madzi ozizira pa 28 °C; ndi kuthekera koyendetsa ma shrimp, nsomba ndi nkhanu pa conditioner imodzi popanda kukonzanso kwakukulu pakati pa maphikidwe. Mtengo unali wachiwiri.
Chifukwa Chake Chowongolera Chachiwiri Chinakhala Chofunikira Kwambiri
Mafakitale ambiri ophera mapellet m'gulu la 1-5 T/H okhala ndi chowongolera chimodzi. Pa chakudya cha nkhuku ndi ziweto zambiri, chipinda chimodzi chokhala ndi masekondi 30-40 osungira ndi chokwanira. Pa chakudya cha nkhanu sichikwanira. Zolemba zamakampani zimagwirizana ndi chifukwa chomwecho: chakudya cha nkhanu chimapangidwa pa chinyezi cha 17-18% ndi kutentha kwa 85-90 °C, zonse ziwiri zimakhala zapamwamba kwambiri kuposa chakudya cha nkhuku, ndipo kugwira ntchito kogwirizana kumadalira kufalikira kwa starch ndi kuchepa kwa mapuloteni pang'ono, zomwe zimafuna chinyezi chambiri komanso kutentha kwambiri kuposa momwe chowongolera chimodzi chingaperekere.
Chokometsera cha magawo awiri chimathetsa izi pang'onopang'ono. Chipinda choyamba chimagwira ntchito ngati chokometsera: chopukutira chimalowa kutentha kozungulira, nthunzi imalowetsedwa kudzera m'mitsempha yambiri, ndipo chokometsera chopondera chimayendetsa zinthuzo patsogolo pamene kutentha kumakwera kufika pa 75-80 °C ndi chinyezi kufika pa 16-17%. Chipinda chachiwiri chimagwira ntchito ngati gawo losungira/kukhwima: palibe nthunzi yowonjezera yomwe imawonjezedwa, koma liwiro lochepekera la chokometsera ndi njira yayitali ya shaft zimapangitsa kuti zinthuzo zigwirizane ndi malo otentha komanso onyowa kwa masekondi ena 30-40, zomwe zimapangitsa kutentha kufika pa 85-90 °C ndi chinyezi kufika pa 17.5-18%. Nthawi yonse yokhalamo ili mu masekondi 80-100 - kuwirikiza kawiri kuposa makina amodzi - zomwe ndi zomwe kapangidwe ka chakudya cha nkhanu kamafunikira kuti kafike pa 95%+ PDI.
Kasitomala adapita kwa ogulitsa atatu omwe akupikisana nawo panthawi yopereka mavoti. Mmodzi adapereka makina okhala ndi gawo limodzi pamtengo wotsika kwambiri; kampani yaku Europe idapereka makina okhala ndi gawo limodzi okhala ndi chowongolera chakunja (makamaka zombo ziwiri zotsatizana zokhala ndi chitoliro chosamutsira pakati pawo). Hongyang SZLH420 yokhala ndi chowongolera chachiwiri chophatikizidwa inali kapangidwe kokha ka chidutswa chimodzi komwe kadamupatsa masekondi 90 a chowongolera mu chimango chimodzi chophatikizidwa, chokhala ndi PLC loop imodzi ndi siteshoni imodzi yoyendetsera. Kuphatikiza kumeneko - komanso mfundo yakuti chowongolera, chute yodyetsa ndi hopper zonse zimapangidwa ndi chitsulo chosapanga dzimbiri kuti zisawonongeke ndi mpweya wa m'mphepete mwa nyanja wa Pathein wolemera chloride - chinali chifukwa chachikulu.
Kapangidwe ka Zida ndi Kuyenda kwa Njira

Chokometsera cha magawo awiri chimagwiritsa ntchito malo olumikizirana achitsulo chosapanga dzimbiri, jakisoni wa nthunzi wozungulira, ndi ma paddle otulutsa mpweya mwachangu. Ma valve a nthunzi olamulidwa ndi PLC amasintha kuthamanga kwa mpweya m'malo okwana 2-4 bar; woyendetsa amangoyika kutentha komwe kukufunika pa HMI, ndipo wowongolera amadula kayendedwe ka nthunzi masekondi awiri aliwonse. Sensa ya PT100 pamalo otulukira chipinda chachiwiri ndi chizindikiro chotsekedwa.
Kutumiza ndi Zotsatira za Mwezi Woyamba
Hongyang anatumiza mainjiniya woyambitsa ntchito ku Pathein kwa masiku 12. Masiku atatu oyamba anagwiritsidwa ntchito kutsimikizira kuchuluka kwa nthunzi kuchokera ku boiler ya biomass ya kasitomala ya matani 4, kukonza masensa otenthetsera, ndikuyesa mphero popanda kanthu. Masiku asanu ndi limodzi otsatira anagwiritsidwa ntchito poyendetsa mitundu inayi - cholima 35% cha mapuloteni akuda akuda, chomaliza cha 28% cha CP vannamei, chakudya cha nkhanu cha CP cha 30%, ndi chodyetsa tilapia cha CP cha 20% - ndikukonza kuthamanga kwa nthunzi ndi liwiro la chowongolera chilichonse pa njira iliyonse. Masiku atatu omaliza anali okhudza kupereka kwa operekera, njira zotsekera, ndi gawo loyesera la Holmen PDI lomwe gulu la QC la kasitomala lidzabwereza mwezi uliwonse.
Mwezi woyamba wathunthu wa ntchito ziwiri unapereka zotsatira zotsatirazi pa chakudya cha nkhanu chokwana matani 1,500 chomalizidwa:
Kuchuluka kwa mphamvu pa ola limodzi (1.8 mm die): cholinga cha 2.0 T/H / chakwaniritsidwa 2.4 T/H
PDI, Holmen masekondi 30: cholinga >= 95.0% / chakwaniritsidwa 95.6%
Kukhazikika kwa madzi, 28 °C madzi osagwedezeka a m'nyanja: cholinga >= maola 3.0 / kukwaniritsidwa maola 3.6
Kutentha kwa mpweya, chotulutsira chachiwiri: cholinga 85-90 °C / kufika 87.4 °C
Chinyezi chikazizira: cholinga <= 12.5% / chakwaniritsidwa 12.1%
Zindapusa zomwe zili m'thumba lomalizidwa: cholinga <= 2.0% / zomwe zakwaniritsidwa 1.4%
Mphamvu yeniyeni, mphero + chowongolera: cholinga <= 45 kWh/t / chakwaniritsidwa 42.8 kWh/t
Mwiniwakeyo adanena kuti kusintha kwakukulu kwa khalidwe la dziwe kunali m'masabata awiri oyambirira: ma pellets a chakudya anakhalabe osawonongeka nthawi yonse yodyetsa maola anayi, dothi m'madziwe linachepa chifukwa ndalama zochepa zolipirira zinali kulowa m'madzi, ndipo chiŵerengero cha kusintha kwa chakudya pa 35% CP black tiger chinakwera kuchoka pa 1.55 (ndi chakudya chomwe chinatumizidwa kale) kufika pa 1.42. Komabe, phindu lalikulu linali la zinthu: kasitomala anasiya kuyika maoda adzidzidzi sabata iliyonse a magalimoto akuluakulu aku Thailand ndipo anayamba kukonza nthawi yopangira zinthu motsutsana ndi nthawi yake yaulimi, zomwe zinachotsa masiku pafupifupi 8-10 a zinthu zomwe zinali m'mabuku ake.
Utumiki, Zida Zosinthira ndi Kukhalapo Kwapafupi
Mzere wodyetsa nsomba za nkhanu womwe umasiya kugwira ntchito nthawi ya vannamei si mzere womwe umapeza ndalama zake. Kudzipereka kwa Hongyang pantchitoyi kumaphatikizapo ulendo wokonzekera wa miyezi 6 ndi mainjiniya wachigawo ku Yangon, zida zosinthira zomwe amalangiza (seti imodzi ya zipolopolo zozungulira, ma ring dies awiri, ma agitator paddles, ma bearings ndi zida zosindikizira zokhazikika) zotumizidwa ndi mzerewo ndikusungidwa m'nyumba yosungiramo katundu ya kasitomala ku Mandalay, komanso zenera loyankhira la maola 24 kuti alandire chithandizo cha kanema kuchokera ku ofesi yayikulu ya Jiangsu. Zida zovalira nthawi zonse zimasungidwa ku nyumba yosungiramo katundu ya Mandalay kuti zikafike ku Pathein mkati mwa maola 36 pamsewu.
Mapeto
Kukhazikitsa kwa Pathein kukuwonetsa njira yomwe yafala kwambiri ku Southeast Asia kuyambira 2023: woyendetsa ulimi wa nsomba wotsogola, wotopa ndi kusintha kwa chakudya chochokera kunja, amasankha kukhazikitsa mzere wocheperako, wopangidwa bwino wa aquafeed momwe gawo lokonzekera limapangidwira zenizeni za kapangidwe ka nkhanu ndi nkhanu, osati kwa pellet wamba wa ziweto. Chowongolera chazitali ziwiri chophatikizidwa mu mzere wa 2-3 T/H ring die, pamlingo uwu, ndiyo njira yotsika mtengo kwambiri yofikira 95% PDI ndi kukhazikika kwa madzi kwa maola atatu komwe famu ya nkhanu imafunikiradi. Kwa Hongyang, nkhaniyi ikutsimikizira kuti kukula kwotsatira pamsika wa aquafeed m'chigawochi sikudzapambana pa matani a pellet-mill okha, koma paukadaulo wokonza womwe umatsimikiza ngati ma pellet amenewo apulumuka ulendo wochokera ku thumba kupita ku dziwe.
