Technology rau kev tshuaj xyuas cov khoom tshiab-txiav los ntawm teb mus rau hauv tsev, kev lag luam lossis kev lag luam hauv chav ua noj yog sophisticated li nws puas tau.
Tab sis tib neeg qhov tseem ceeb tseem yog qhov tseem ceeb.
Cov kws tshaj lij hais tias cov khoom txiav tshiab muaj kev nyab xeeb thiab zoo dua qub dua qub. Nyob nruab nrab ntawm cov kev kawm hauv kev lag luam, HACCP (Hazard Analysis thiab Critical Control Points) cov txheej txheem, kev soj ntsuam thev naus laus zis, kev tshuaj xyuas, kev kuaj sim (ntawm qee qhov chaw) thiab lwm yam kev tiv thaiv, cov txheej txheem muaj peev xwm ua tau raws li cov neeg siv khoom xav tau kom muaj kev nyab xeeb thiab cov khoom tshiab thiab saj. .
Tab sis txhua txoj hauv kev, kev tshuaj xyuas hauv ib daim ntawv lossis lwm qhov yog qhov tseem ceeb.
"Nws pib tawm nrog cov khoom xa tuaj," said United Fresh Vice President of Food Safety and Technology David Gombas. “Koj tsis tuaj yeem ua qhov zoo tshiab-txiav tawm ntawm tag nrho cov khoom phem.
"Koj yuav tsum pib nrog cov khoom zoo tshaj plaws."
Cov cuab yeej siv kuj yog ib qho tseem ceeb, nws hais ntxiv.
Gombas tau hais tias "Txoj kev nrawm tshaj plaws kom poob qhov zoo hauv kev ua haujlwm tshiab yog riam phom," Gombas tau hais. "Lub sharper riam, qhov zoo ntawm cov khoom."
Nyob rau tiam thib peb, tsev neeg muaj McEntire Produce hauv Columbia, South Carolina, Tus Lwm Thawj Coj Thawj Coj Tom Lovelace tau hais tias HACCP cov ntsiab lus qhia lub tuam txhab cov txheej txheem txij thaum pib mus txog thaum xaus. Tom qab ntawd, McEntire tau txiav txim siab tawm tswv yim kom muaj cov chaw ua haujlwm zoo thiab kev nyab xeeb thiab cov neeg ua haujlwm sib cais kom cov peev txheej tsis tau diluted thiab txhua cheeb tsam tau txais kev sib npaug.
Lovelace hais tias "Txhua tus txheej txheem ntsuas cov ntsiab lus tseem ceeb tswj hwm thiab saib xyuas ntawm lub sijhawm meej," Lovelace hais.
Thiab nws yog txheej txheem uas tso siab rau qhov sib npaug ntawm cov cuab yeej technology thiab tib neeg.
"Koj muaj cov tshuab tshuab hauv qhov chaw - cov tshuab tsis siv neeg nyob hauv qhov chaw - tab sis nws yog cov neeg ua ob yam," Lovelace hais. “Lawv tsim cov kauj ruam uas yuav tsum tau ua hauv thawj qhov chaw. Thiab lwm yam uas lawv yuav tsum tau ua yog xyuas kom cov kev cuam tshuam tau ua haujlwm.
"Muaj cov kauj ruam pov thawj uas yuav tsum tau ua, thiab lawv tau ua los ntawm tib neeg. Tsis muaj kev hloov pauv rau cov neeg muaj kev paub dhau los, muaj peev xwm ua tau zoo. "
Lub tuam txhab tuav kev sib raug zoo nrog cov neeg cog qoob loo tshwj xeeb uas yuav tsum ua raws li nws "cov lus qhia nruj." Ntawm lwm yam, McEntire tsim cov nplooj ntsuab tshiab, dos, kua txob, txiv lws suav, zaub qhwv thiab carrots, feem ntau rau kev pabcuam zaub mov hauv khw noj mov ceev.
"Peb muaj cov neeg tuaj xyuas cov neeg cog qoob loo kom paub tseeb tias lawv tau ua raws li peb cov qauv," Lovelace tau hais. "Nws yog ib feem loj ntawm qhov peb ua, ob qho tib si los ntawm qhov zoo thiab qhov pom kev nyab xeeb ntawm zaub mov."
Kev ua tiav txuas ntxiv los ntawm kev thauj mus los thiab tuaj txog ntawm lub qhov rooj txais. Nyob ntawm seb cov khoom siv los ntawm qhov twg, nws tuaj yeem ntau npaum li tsib hnub ntawm kev sau qoob loo thiab tuaj txog ntawm McEntire qhov chaw ua haujlwm, yog li pib nrog cov khoom zoo thiab kev tswj xyuas cov hlua txias yog qhov tseem ceeb tshaj.
McEntire xav kom nws cov khoom raug xa mus rau hauv cov tsheb thauj khoom uas dais "siv ib leeg-siv tsis-siv cov ntsaws ruaj ruaj" affixed thaum thauj khoom tiav. Yog tias lub foob tau tawg thaum tuaj txog, ib qho txheej txheem sib txawv yog ua haujlwm los daws nws, uas yuav suav nrog kev tsis lees paub lub nra.
"Kev saib xyuas, kev saib xyuas thiab kev tswj hwm yog ib feem tseem ceeb ntawm peb cov khoom siv raw," Lovelace tau hais, sau tseg tias lub tuam txhab yuav tsum tau saib xyuas qhov kub thiab txias txhua txoj hauv kev.
Cov khoom lag luam raug tshuaj xyuas thaum tuaj txog - ib yam li lub tsheb thauj khoom nws tuaj, txhawm rau xyuas kom huv.
Los ntawm qhov ntawd, nws yuav tshuaj xyuas thiab ua li cas yog nyob ntawm cov khoom muag. Lub taub hau ntawm iceberg lettuce tuaj nyob rau hauv ntau huv dua, hais, xoob nplooj ntsuab.
"Koj cov kab tau tsim los daws qhov ntawd," Lovelace tau hais. "Muaj cov cwj pwm sib txawv ntawm cov ntsiab lus sib txawv hauv cov txheej txheem uas koj tab tom nrhiav."
Kev tshuaj xyuas los ntawm tib neeg lub qhov muag yog ib kauj ruam tseem ceeb, raws li cov neeg ua haujlwm nrhiav thiab tshem tawm cov nplooj lettuce bruised, los yog tsis xws luag hauv dos lossis txiv lws suav, piv txwv li. Txawm hais tias nws tau txiav ua ntej ntxuav lossis rov ua dua, feem ntau cov khoom tau yaug ob peb zaug. Technology ncaws pob hauv hluav taws xob saib xyuas dej thiab microbial.
Ntawm McEntire, tag nrho cov khoom mus dhau lub ntsuas hlau kom paub tseeb tias tsis muaj cov khoom hlau txawv teb chaws nyob ua ntej nws tau ntim rau kev xa khoom.
Gombas tau piav qhia txog qhov nws tau pom thaum soj ntsuam kev tsim khoom ntawm lub chaw ua haujlwm loj uas txhua lub hnab zaub xam lav raug tshuaj xyuas thaum lawv tawm ntawm kab.
"Muaj 100 feem pua kev tshuaj xyuas ntawm cov hnab ntawd," nws hais. "Raws li nws tab tom tawm ntawm txoj kab ntim khoom, muaj qee tus neeg tshuaj xyuas (kom paub tseeb tias) tsis muaj dab tsi cuam tshuam nrog cov khoom."
Qee cov nroj tsuag ua cov tshuaj microbiological ntawm cov khoom thaum tuaj txog ntawm cov nroj tsuag thiab cov khoom ntim khoom ua ntej nws tso tawm.
Optical sorters have also made a big impact on the inspection process – particularly since laser technology replaced the cameras of the 1990s for screening lettuce, said Rudi Groppe, president and CEO of Heinzen Manufacturing International and one of the instructors for the University of California Davis Postharvest Technology Center’s Fresh-Cut Products Workshop.
"Lawv tab tom nrhiav iav, ntoo, hlau ... txhua yam nas, nab, qav - txhua yam sib txawv," Groppe hais. "Thiab lub peev xwm los ntes chlorophyll yog qhov hloov pauv tiag tiag, vim tias tsis yog siv lub koob yees duab duab koj tab tom saib nws rau xim. Nrog lub invention ntawm lub laser thiab nrog LED optics ... lawv muaj peev xwm txiav txim siab translucency theem.
"Lub koob yees duab thev naus laus zis yuav hais tias nws yuav yog cov khoom lag luam zoo. Nrog lub laser, thiab cov khoos phis tawj siab ceev, nws tuaj yeem paub cov xim” thiab yog li pom ntawm, hais tias, nplooj ntawm nplooj ntsuab nplooj thiab daim iav ntsuab.
Groppe kwv yees li ntawm 60 thiab 70 feem pua ntawm cov txheej txheem niaj hnub no siv cov khoom siv kho qhov muag. McEntire yog ib tug ntawm lawv.
Txawm li cas los xij, Groppe ntseeg hais tias tom ntej no frontier rau sorting technology yuav txo tau tom qab sorting poob rau processors los ntawm kev khiav cov khoom tsis lees paub los ntawm ib tug thib ob sorting voj voog.
"Hais yog tias koj tab tom khiav ib txoj kab ntawm 6,000 phaus ib teev thiab koj yuav muaj tsib kab, nrog rau 10 feem pua tsis lees paub tus nqi, uas yog qhov loj," Groppe hais. "Nws tuaj yeem txo qis me ntsis ntawm cov khoom zoo nrog qhov nws pom tias tsis zoo."
Bjorn Thumas, tus thawj coj ntawm kev txhim kho kev lag luam / khoom noj rau TOMRA, hais tias nws lub tuam txhab Nimbus freefall laser sorter thiab siv lub koob yees duab thiab laser sorter hu ua Genius muaj peev xwm los sib sau ua ke peb txoj kev sorting module. Featuring ob lub ejector modules, lawv tso cai rau cov txheej txheem los tsim cov kwj deg cais.
"High-speed, precision pa phom tshem tawm cov khoom lag luam thiab cov khoom txawv teb chaws hauv ob kauj ruam," nws hais. "Qee zaum, qhov kev tsis lees paub thib ob tau txheeb xyuas zaum ob."
Txog tam sim no, cov txheej txheem peb-txoj kev thiab rov txheeb cov txheej txheem feem ntau yog siv rau cov taum ntsuab.
Txawm li cas los xij, txawm li cas los xij, kev tshuaj xyuas kom muaj txiaj ntsig zoo thiab kev nyab xeeb ntawm txhua kauj ruam yog lub hauv paus ntawm kev nyab xeeb thiab ua tiav cov txheej txheem tshiab txiav.
"Kuv cov neeg siv khoom tsis xav tias kuv tab tom cuam tshuam nrog cov khoom siv raw khoom sib txawv. Lawv cia siab tias kuv yuav tswj tau qhov ntawd, "Lovelace hais. "Lawv cia siab tias nws yuav ua tau zoo txhua lub sijhawm thiab nws yog peb txoj haujlwm kom ua tau li ntawd."
