Cov khoom siv tsim

Cov lag luam tsim khoom tau muaj nws feem ntawm cov teeb meem kev nyab xeeb zaub mov nyob rau xyoo tas los no.

Tiam sis nws tsis yog nws ib leeg xwb.

Thaum lub rooj sib tham txog kev kawm ntawm United Fresh 2012 hauv Texas, Margaret Hardin, Ph.D., tus lwm thawj coj ntawm kev pabcuam kev txawj ntse rau IEH Laboratories thiab Consulting Group, tau hais tias kev lag luam tsim khoom yuav ua tau zoo los kawm los ntawm nws cov phooj ywg hauv nqaij thiab mis nyuj.

"Kev lag luam mis nyuj tau daws qhov teeb meem no, kev lag luam nqaij tau daws qhov teeb meem no," nws hais. "Kuv vam tias kev lag luam khoom noj khoom haus yuav kawm tam sim no los ntawm qhov lawv tau ntsib dhau los ob peb xyoos dhau los los sau lawv keeb kwm."

Kev ua qias tuaj ntawm cov nqaij thiab nqaij qaib hauv xyoo 1980 ua rau muaj ntau txoj cai kev nyab xeeb zaub mov nyob rau hauv cov phau ntawv niaj hnub no, Hardin tau hais, uas tau ua ntau qhov kev ntsuam xyuas kev nyab xeeb zaub mov hauv cov chaw ua zaub mov ntau xyoo dhau los.

Yam koj tsis pom
Nws hais tias, feem ntau yuav ntsib kev tsis lees paub - cov thawj coj thiab cov neeg ua haujlwm uas tsis ntseeg tias kev ua qias tuaj yeem tshwm sim hauv lawv cov chaw. Qhov ntawd yog vim qhov ua rau feem ntau zais - hauv cov ces kaum thiab qhov chaw me me.

Tiamsis txhua yam uas kov cov khoom noj muaj peev xwm ua rau muaj kuab paug. Thiab qhov ntawd yog qhov tseem ceeb heev.

Siv cov hollow rollers. Hardin hais tias tsis yog lub tswv yim zoo, vim tias lawv muaj peev xwm los ua "qhov chaw loj hlob ntawm cov kab mob me me ... qhov chaw nkaum cov kab mob tom qab kev ntxuav tas li."

"Yog tias koj muaj ntxhiab tsw phem hauv thaj chaw huv si, ces muaj kab mob me me," nws hais.

Hardin hais tias cov chaw loj hlob ntawm cov kab mob me me nyuaj rau ntxuav, hais txog cov foob hydraulic hnav, cov saw hlau thiab cov hniav tiv thaiv, O-rings, gaskets, sab hauv ntawm cov txee thiab cov ledges ua cov neeg ua txhaum.

"Cov khoom siv thauj khoom - cov thav duab - puas yog lawv khoob? Cov ceg rooj puas yog khoob?" nws hais.

Yog tias yog li ntawd, nws pom zoo kom hloov lawv nrog cov khoom khov, piav qhia zaj dab neeg ntawm tus neeg siv khoom uas nyuam qhuav xaj ntau lub rooj tshiab nrog cov txee, cov ntsia hlau teeb tsa thiab cov ceg khoob.

"Kuv yuam kom nws xa lawv rov qab," nws hais. Cov thawv hluav taws xob tuaj yeem dhau los ua cov chaw me me. "Sab hauv lub thawv vaj huam sib luag, nyob ib puag ncig cov gaskets, hauv thiab ib puag ncig cov nyees khawm pib/nres thiab cov kev kaw thaum muaj xwm txheej ceev - yog tias muaj ib tug neeg ua haujlwm ntawm kab, lawv kov cov khoom, tom qab ntawd kov cov nyees khawm, lub khawm qhib-kaw ntawd yog qhov chaw kov zaub mov," nws hais.

Cov kev daws teeb meem? Yooj yim, raws li Hardin hais.

"Yog koj tsis paub meej, rhuav cov khoom siv," nws hais. "Siv cov ntaub so ntswg los so."

Yog tias koj muaj ib yam dab tsi uas ntsia hlau rau, ntsia hlau rau hlau - txhua qhov chaw uas dej nkag tau, muab nws rhuav tshem. Cov no tau raug sau tseg tias muaj cov kab mob me me nyob rau hauv qee lub nroj tsuag.

Qhov tseeb, cov niches loj hlob yuav tsum tau tsim tawm ntawm lub kaw lus lossis tswj hwm ua ib feem ntawm cov txheej txheem, nws hais.

Cov yam ntxwv yooj yim ntxuav
Cov qauv tsim khoom siv tshiab rau cov khoom txiav tshiab yuav zoo li coj ib nplooj ntawv los ntawm Hardin phau ntawv.

Rudi Groppe, tus thawj tswj hwm thiab tus thawj coj kev tsim kho rau Heinzen Manufacturing International, cov tshuab no tau raug tsim los nrog cov qauv qhib kom tso cai rau "muaj peev xwm ntxuav tag nrho."

“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.”

Cov neeg ua haujlwm hauv kab tuaj yeem tsa cov siv sia thiab ntxuav lub cev hauv txhua qhov

Yog tias koj muaj ib cheeb tsam uas koj tsis pom ntawm ib yam khoom siv, nws nyuaj rau lees paub tias koj tau ntxuav nws tiag.

Nws hais tias cov tshuab ntxhua khaub ncaws tam sim no muaj cov siv sia uas tsim los qhib rau kev nkag mus rau hauv kev ntxuav kom huv si, thiab qee qhov tsis muaj sab kiag li. Qee lub tshuab ntxhua khaub ncaws tshiab muaj sab thiab cov siv sia uas tig tau qhib.

"Kev ua cov kav dej thiab cov kav dej tam sim no tau hloov mus rau 100 feem pua ​​​​​​cov yeeb nkab stainless piv rau cov yeeb nkab PVC, vim tias biofilm yog qhov txaus ntshai rau kev nyab xeeb zaub mov uas yuav tsis ploj mus," Groppe hais.

Muaj ib hnub, cov kav dej no yuav tsum tau ntxuav kom huv si siv dej kub los yog siv tshuaj kho mob kaw, thiab "ntau tus neeg siv khoom yuav nyob rau pem hauv ntej yog tias qhov no dhau los ua tus txheej txheem tu cev huv si," nws hais ntxiv.

Siv cov tshuab cua los ntxuav siv txoj siv yog ib qho uas siv ntau niaj hnub no, txawm hais tias cov tshuab cua tsim cua sov uas tsim ib puag ncig uas cov kab mob tuaj yeem loj hlob. Heinzen cov tshuab cua tau tsim los kom lub impeller tuaj yeem rub tawm ntawm lub tsev kom yooj yim ntxuav.

CombiScale lub tshuab ntsuas ntau lub taub hau kuj tseem ua los ntawm lub thav qhib. Lub hopper tig tau uas tsis tas siv cuab yeej nyob rau sab saum toj tsuas yog yuav tsum tau tsiv mus rau sab xwb, tsis tas yuav tsum tau qhib thiab muab sib cais, kom ntxuav tau. Cov khoom siv hluav taws xob khaws cia rau hauv lub txee deb uas tuaj yeem nyob deb ntawm cov khoom siv.

Thaum koj ntxuav thiab tua kab mob, tsis muaj kev pheej hmoo ntawm kev nkag mus rau hauv cov khoom siv hluav taws xob vim tias tam sim no cov khoom siv hluav taws xob tuaj yeem teeb tsa txog li 20 feet
"mus deb," Nick Taraborelli, tus lwm thawj coj ntawm kev muag khoom thiab kev lag luam rau CombiScale. Qhov ntawd yog ib qho txiaj ntsig loj hauv qhov chaw ntxuav dej, vim tias koj tus yeeb ncuab phem tshaj plaws yog dej nkag mus rau hauv koj cov khoom siv hluav taws xob.

Nrog rau kev loj hlob uas Taraborelli tau hais tias nws lub tuam txhab tau pom hauv kev lag luam txiav tshiab, cov khoom siv uas tau tsim los rau kev ntim khoom noj qhuav yuav nyuaj dua rau kev ntxuav thaum siv rau hauv cov ntawv thov txiav tshiab.

"Kuv xav hais tias hauv kev lag luam khoom noj khoom haus, peb feem ntau sib tw nrog cov yam ntxwv," Taraborelli hais. "Hauv kev lag luam khoom noj txom ncauj, vim tias lawv tsis ntxuav lawv cov tshuab zoo li kev lag luam txiav tshiab (yuav tsum tau), cov yam ntxwv no feem ntau raug tsis quav ntsej, thaum nyob hauv kev lag luam khoom noj khoom haus, kev ntxuav yog qhov tseem ceeb heev.

"USDA tau tsom ntsoov rau kev ua kom cov tuam txhab ua raws li tus qauv siab dua."
