Naqshadaynta qalabka

Warshadaha wax soo saarka ayaa sanadihii ugu dambeeyay la kulmay caqabado la xiriira badqabka cuntada.

Laakiin kaligeed ma aha.

Isagoo ka hadlayay kulan waxbarasho oo ka dhacay United Fresh 2012 Texas, Margaret Hardin, Ph.D., madaxweyne ku xigeenka adeegyada farsamada ee IEH Laboratories and Consulting Group, ayaa sheegtay in warshadaha wax soo saarka ay ku fiicnaan doonaan inay wax ka bartaan asxaabtooda hilibka iyo caanaha.

"Warshadaha caanaha ayaa wax ka qabtay, warshadaha hilibka ayaa wax ka qabtay," ayay tiri. "Waxaan rajeynayaa in warshadaha wax soo saarka ay hadda wax ka baran doonaan wixii ay soo mareen labadii sano ee la soo dhaafay si ay u qoraan taariikhdooda."

Wasakhowga hilibka iyo digaagga ee laga sameeyay hilibka digaagga sanadihii 1980-meeyadii ayaa horseeday in maanta la sameeyo xeerar badan oo ku saabsan badqabka cuntada, ayuu yiri Hardin, kaasoo sanadihii la soo dhaafay maareeyay qiimeyno badan oo ku saabsan badqabka cuntada ee goobaha lagu sameeyo cuntada.

Waxa aadan arki karin
Waa wax caadi ah, ayay tiri, in lala kulmo dafiraad - maamulayaasha iyo shaqaalaha aan aaminsanayn in wasakhdu ay ka dhici karto xarumahooda. Taasi waa sababta oo ah sababta badanaa waa la qariyaa - meelaha qaar.

Laakiin wax kasta oo taabta dusha sare ee cuntada waxay yeelan karaan awood ay ku wasakhoobaan. Waana meesha qalabku aad muhiim u yahay.

Qaado duubabka godka ah. Fikrad fiican maaha, ayuu yiri Hardin, sababtoo ah waxay leeyihiin awood ay ku noqdaan "meelo koritaanka microbial-ka ah ... oo hoy u ah noolaha ka dib nadaafadda caadiga ah."

"Haddii aad leedahay ur xun oo ku yaal meel nadiif ah, waxaa jira meel microbial ah," ayay tiri.

Hardin wuxuu yiri meelaha koritaanka microbial-ka way adag tahay in la nadiifiyo, isagoo soo hadal qaaday shaabadaha haydarooliga ee duugoobay, ilaalada silsiladda iyo daabka, giraanta O-rings, gaskets, gudaha armaajooyinka iyo meelaha lagu dhejiyo inay yihiin dambiilayaal suurtagal ah.

"Qalabka qaada - qaab-dhismeedka - ma yihiin kuwo godan? Ma lugaha miiska ma godan yihiin?" ayay tiri.

Hadday sidaas tahay, waxay ku talisay in lagu beddelo kuwo adag, iyadoo la sheegayo sheekada macmiil dhawaan dalbaday miisas cusub oo leh khaanado, boolal iyo lugo godan.

"Waxaan ku qasbay inuu dib u celiyo," ayay tiri. Sanduuqyada guddiga korontada waxay noqon karaan meelo yaryar. "Gudaha sanduuqa guddiga, hareeraha gaskets-ka, gudaha iyo hareeraha badhamada bilowga/joojinta iyo daminta degdegga ah - haddii qof uu ka shaqeynayo khadka, waxay taabanayaan alaabada, ka dibna waxay taabanayaan badhamada, badhanka daminta waa dusha sare ee cuntada," ayay tiri.

Xalku ma fudud yahay, sida uu qabo Hardin.

"Haddii aadan hubin, qalabka jebi," ayay tiri. "Qaado suufka.

"Haddii wax aad ku xiran tahay, lagu xiray, bir ilaa bir - meel kasta oo biyuhu geli karaan, kala qaad. Kuwaas dhammaantood waxaa lagu diiwaangeliyey meelo yar yar oo ka mid ah dhirta."

Xaqiiqdii, meelaha kobaca waxay u baahan yihiin in laga sameeyo nidaamka ama la maareeyo iyadoo qayb ka ah geeddi-socodka, ayay tiri.

Sifooyinka nadiifinta fudud
Naqshadaha qalabka cusub ee loogu talagalay alaabada cusub ee la jarjaray waxay noqon karaan bog ka mid ah buugga Hardin.

Rudi Groppe, madaxweynaha iyo maareeyaha injineernimada Heinzen Manufacturing International, Mashiinnada ayaa la abuurayaa iyadoo la adeegsanayo naqshado furan si loo oggolaado "awoodda nadiifinta oo buuxda."

“All conveyor designs incorporate some form of sanitation access,” Groppe said. “As the process moves from low-risk to high-risk, we see all conveyors with quick-release take-ups to relieve belt tension, belt lifters to allow frame access and CIP spray bar systems to minimize water consumption and labor to sanitize the belt.”

Shaqaalaha khadka ayaa kor u qaadi kara suunka oo si jidh ahaan ah u dhaqi kara dhammaan

"(Haddii aad haysato) meel aadan si muuqaal ah uga arki karin qalab, way adag tahay in la xaqiijiyo inaad dhab ahaantii nadiifisay."

Nidaamyada dhaqidda hadda waxay leeyihiin suunka gudbiyaha oo loogu talagalay in loo furo si loo helo marin dhammaystiran oo nadaafadeed, ayuu yiri, qaarna ma laha dhinacyo haba yaraatee. Qaar ka mid ah qalabka qaada haamaha dhaqidda ee cusub waxay leeyihiin dhinacyo iyo suunno furan.

"Hagaajinta tuubooyinka iyo tuubooyinka hadda waxay u wareegeen 100 boqolkiiba tuubo aan miridh lahayn marka loo eego tuubooyinka PVC, maadaama biofilm-ku uu yahay khatar badbaado cunto oo aan dhammaan doonin," ayuu yiri Groppe.

Waqti ka mid ah, dhuumaha noocan oo kale ah waxay u baahan yihiin in la nadiifiyo iyadoo la adeegsanayo daaweynta biyaha kulul ama nidaamka daaweynta kiimikada ee wareegga xiran, "dhowr macaamiil ayaa ku jiri doona safka hore ee qalooca haddii tani ay noqoto hab nadaafadeed oo caadi ah," ayuu raaciyay.

Isticmaalka afuufaha hawada ee nadiifinta suunka ayaa ah wax caadi ah maalmahan, inkastoo afuufaha ay dhaliyaan kuleyl abuura jawi ay bakteeriyadu ku kori karto. Afuufaha Heinzen waxaa loogu talagalay in afuufaha si jir ahaan looga soo saaro guriga si loo fududeeyo nadaafadda.

Miisaanka madax-badan ee CombiScale sidoo kale waxaa lagu dhisay qaab furan. Hopper wareeg ah oo aan qalab lahayn oo dusha sare ku yaal wuxuu u baahan yahay in loo raro dhinaca, halkii laga furi lahaa oo la kala qaadi lahaa, si loo nadiifiyo. Qalabka elektaroonigga ah waxaa lagu kaydiyaa armaajo fog oo laga heli karo meel ka fog qalabka.

"Marka aad nadiifinayso oo aad nadiifinayso, ma jirto khatar ah in biyo lagu helo qalabka elektaroonigga ah sababtoo ah hadda qalabka elektaroonigga ah waxaa lagu rakibi karaa ilaa 20 cagood."
"Aad ayaan u faraxsanahay," ayuu yiri Nick Taraborelli, madaxweyne ku xigeenka iibka iyo suuqgeynta ee Isku-darka Cabbirka. "Taasi waa faa'iido weyn oo ku jirta xarunta nadaafadda, sababtoo ah cadowgaaga ugu xun waa biyaha oo galaya qalabkaaga elektaroonigga ah."

Iyadoo kobaca uu sheegay in shirkaddiisu ay ku arkaysay warshadaha cusub, qalabka asal ahaan loogu talagalay in lagu xiro cuntooyinka fudud ee qalalan ayaa laga yaabaa inay aad u adag tahay in la nadiifiyo marka loo isticmaalo codsiyada cusub.

"Waxaan dhihi lahaa warshadaha wax soo saarka, waxaan inta badan ku tartannaa sifooyinka," ayuu yiri Taraborelli. "Warshadaha cuntada fudud, sababtoo ah ma nadiifiyaan mashiinadooda sida warshadaha cusub (waa inay nadiifiyaan), sifooyinkan badanaa waa la dayacaa, halka warshadaha wax soo saarka, nadiifintu aad bay muhiim u tahay.

"USDA waxay diiradda saartay sidii shirkadaha loogu hayn lahaa heer aad u sarreeya."
