Posungirako bwino, chinyezi (MC) mu chimanga chomwe chimakololedwa nthawi zambiri chimakhala chapamwamba kuposa 12% mpaka 14% wet basis (wb).Pofuna kuchepetsa MC kumalo osungirako otetezeka, m'pofunika kuumitsa chimanga.Pali njira zingapo zowumitsa chimanga.Kuyanika kwachilengedwe mu thanki kumachitika pamalo owuma kuchokera ku 1 mpaka 2 mapazi wokhuthala komwe kumayenda pang'onopang'ono kudzera mu nkhokwe.
Nthawi zina kuyanika kwa mpweya wachilengedwe, nthawi yofunikira kuti chimanga chiwume kwathunthu chingayambitse nkhungu munjere, zomwe zimapangitsa kupanga mycotoxins.Pofuna kupewa malire a makina owumitsa mpweya pang'onopang'ono, otsika kutentha, mapurosesa ena amagwiritsa ntchito zowumitsira kutentha kwambiri.Komabe, kusinthasintha kwa mphamvu komwe kumayenderana ndi zowumitsira kutentha kwakukulu kumafuna kuti maso a chimanga awonetsedwe ndi kutentha kwakukulu kwa nthawi yayitali kuyanika kwathunthu kusanathe.Ngakhale mpweya wotentha ukhoza pafupifupi kuumitsa chimanga kuti chisungidwe mu MC yotetezeka, kutentha kwa kutentha komwe kumayenderana ndi njirayi sikukwanira kuti athetse tizilombo toyambitsa matenda, tizilombo toyambitsa matenda monga Aspergillus flavus ndi Fusarium oxysporum.Kutentha kwapamwamba kungayambitsenso pores kung'ambika ndikuyandikira pafupi, zomwe zimapangitsa kuti kutumphuka kupangidwe kapena "kuuma pamwamba", zomwe nthawi zambiri zimakhala zosafunika.M'zochita, maulendo angapo angafunike kuti achepetse kutaya kutentha.Komabe, nthawi zambiri kuyanika kumachitika, mphamvu yowonjezera imafunikanso.
Kwa iwo ndi mavuto ena ODEMADE Infrared Drum IRD imapangidwa.Pokhala ndi nthawi yocheperako, kusinthasintha kwakukulu, komanso kugwiritsa ntchito mphamvu zochepa poyerekeza ndi machitidwe ochiritsira a mpweya wouma, teknoloji yathu ya infrared imapereka njira ina yeniyeni.
Kutentha kwa infrared (IR) kwa chimanga, kumatha kuwumitsa chimanga mwachangu ndikuchiyeretsa popanda kuwononga mtundu wonse.Kuchulukitsa kupanga ndikuchepetsa mphamvu zowumitsa popanda kuwononga chimanga chonse.Chimanga chongokololedwa kumene chokhala ndi chinyezi choyambirira (IMC) cha 20%, 24% ndi 28% chonyowa (wb) chinawumitsidwa pogwiritsa ntchito chowumitsira chowumitsira cha laboratory infrared batch dryer pa pass imodzi ndi ma pass awiri.Zitsanzo zouma zimatenthedwa pa 50 ° C, 70 ° C ndi 90 ° C kwa maola 2, 4 ndi 6.Zotsatira zimasonyeza kuti pamene kutentha kwa kutentha ndi nthawi yotentha kumawonjezeka, kuchotsedwa kwa chinyezi kumawonjezeka, ndipo madzi opangidwa ndi chiphaso chimodzi ndi apamwamba kuposa kawiri;Mchitidwe wofananawo umawonedwa pochepetsa kuchuluka kwa nkhungu.Pamitundu yosiyanasiyana yophunzirira, kutsika kwa nkhungu imodzi yodutsamo kumachokera ku 1 mpaka 3.8 log CFU / g, ndipo ma pass awiriwo anali 0.8 mpaka 4.4 log CFU / g.The infuraredi kuyanika mankhwala chimanga anakulitsidwa ndi IMC ya 24% wb The IR intensities ndi 2.39, 3.78 ndi 5.55 kW / m2, ndipo chimanga akhoza zouma kuti madzi otetezeka zili (MC) 13% (wb) kokha 650 s, 455 s ndi 395 s;nkhungu yofananira imawonjezeka ndi mphamvu yowonjezera Kuchepetsa katundu kumachokera ku 2.4 mpaka 2.8 chipika CFU / g, 2.9 mpaka 3.1 chipika CFU / g ndi 2.8 mpaka 2.9 chipika CFU / g (p> 0.05).Ntchitoyi ikuwonetsa kuti kuyanika kwa chimanga kwa IR kukuyembekezeka kukhala njira yowumitsa mwachangu ndi phindu lomwe lingathe kuwononga chimanga.Izi zitha kuthandiza opanga kuthetsa mavuto okhudzana ndi nkhungu monga kuipitsidwa kwa mycotoxin.
Kodi infrared imagwira ntchito bwanji?
• kutentha kumagwiritsidwa ntchito mwachindunji kuzinthu ndi ma radiation a infrared
• Kutentha kumagwira ntchito kuchokera ku tinthu tating'onoting'ono tamkati
• ndi evaporating chinyezi ikuchitika mankhwala particles
Ng'oma yozungulira yamakina imatsimikizira kusakanikirana kwathunthu kwa zida zopangira ndikuchotsa kupanga zisa.Izi zikutanthawuzanso kuti zakudya zonse zimakhala ndi zowunikira zofanana.
Nthawi zina, imatha kuchepetsanso zowononga monga mankhwala ophera tizilombo ndi ochratoxin.Zolowetsa ndi mazira nthawi zambiri zimapezeka pakatikati pa ma granules, zomwe zimapangitsa kuti zikhale zovuta kwambiri kuzithetsa.
Chitetezo chazakudya chifukwa cha kutentha mwachangu kwa tinthu tating'ono kuchokera mkati - IRD imawononga mapuloteni a nyama popanda kuwononga mapuloteni a zomera.Zoyikapo ndi mazira nthawi zambiri zimapezeka mkatikati mwa ma granules, zomwe zimapangitsa kuti zikhale zovuta kwambiri kuzichotsa.Chitetezo chazakudya chifukwa cha kutentha mwachangu kwa tinthu tating'onoting'ono kuchokera mkati - IRD imawononga mapuloteni a nyama popanda kuwononga mapuloteni a zomera
Ubwino wa Infrared Technology
• kugwiritsa ntchito mphamvu zochepa
• nthawi yochepa yokhalamo
• kupanga mwamsanga pambuyo poyambira dongosolo
• Kuchita bwino kwambiri
• Kusamalira zinthu mwaulemu
