Malo a fakitale ya chakudya

Zida zowunikira zomwe zimagwiritsidwa ntchito m'mafakitale azakudya ndi zakumwa ndizofanana ndi zomwe zimachitika m'mafakitale wamba, kupatula kuti zida zina ziyenera kuchitidwa pansi paukhondo komanso nthawi zina zowopsa.Mtundu wa zinthu zowunikira zomwe zimafunikira komanso miyezo yoyenera zimadalira chilengedwe m'dera linalake;Malo opangira chakudya amakhala ndi malo osiyanasiyana pansi pa denga limodzi.

Mafakitale angaphatikizepo madera ambiri monga kukonza, kusungirako, kugawa, kusungirako firiji kapena youma, zipinda zoyera, maofesi, makonde, maholo, zimbudzi, ndi zina zotero. Dera lirilonse liri ndi zofunikira zake zowunikira.Mwachitsanzo, kuyatsa pokonza chakudyamadera nthawi zambiri amayenera kupirira mafuta, utsi, fumbi, dothi, nthunzi, madzi, zimbudzi, ndi zonyansa zina mumpweya, komanso kuthira madzi opopera pafupipafupi ndi zosungunulira movutikira.

NSF yakhazikitsa njira zozikidwa pazigawo zachigawo komanso kuchuluka kwa kulumikizana mwachindunji ndi chakudya.Muyezo wa NSF wa zinthu zounikira zakudya ndi zakumwa, wotchedwa NSF/ANSI Standard 2 (kapena NSF 2), umagawanitsa malo a zomera m’zigawo zitatu: malo osakhala chakudya, malo opopera madzi, ndi malo a chakudya.

Zowunikira pakukonza chakudya

Monga ntchito zambiri zowunikira, IESNA (North American Lighting Engineering Association) yakhazikitsa milingo yoyenera yowunikira pazinthu zosiyanasiyana zokonza chakudya.Mwachitsanzo, IESNA imalimbikitsa kuti malo oyendera zakudya azikhala ndi zowunikira zoyambira 30 mpaka 1000 fc, malo okhala ndi mitundu ya 150 fc, ndi nyumba yosungiramo zinthu, zoyendera, zopakira, ndi chimbudzi cha 30 fc.

Komabe, popeza chitetezo cha chakudya chimadaliranso kuunikira kwabwino, dipatimenti ya zaulimi ya ku United States imafuna milingo yowunikira yokwanira mu Gawo 416.2(c) la Food Safety and Inspection Service Manual.Table 2 imatchula zofunikira zowunikira za USDA m'malo osankhidwa opangira chakudya.

Kubala bwino kwa mitundu ndikofunikira kuti tiziwunika molondola komanso kuyika mitundu yazakudya, makamaka nyama.Dipatimenti ya zaulimi ku US imafuna CRI ya 70 m'malo opangira chakudya, koma CRI ya 85 madera oyendera chakudya.

Kuphatikiza apo, onse a FDA ndi USDA apanga mafotokozedwe amtundu wa Photometric pakugawa kowunikira molunjika.Kuwala koyang'ana pamwamba kuyenera kuyeza 25% mpaka 50% ya kuyatsa kopingasa ndipo pasakhale mithunzi yomwe ingawononge malo ovuta.

Food Processing Lighting future:

• Poganizira zofunikira zambiri zaukhondo, chitetezo, chilengedwe komanso kuwala kwamakampani azakudya pazida zowunikira, opanga zowunikira zamakampani a LED akuyenera kukwaniritsa zofunikira izi:
• Gwiritsani ntchito zinthu zosakhala ndi poizoni, zolimbana ndi dzimbiri komanso zosagwira moto ngati pulasitiki ya polycarbonate.
• Pewani kugwiritsa ntchito galasi ngati n'kotheka
• Pangani malo akunja osalala, opanda madzi okwanira opanda mipata, mabowo kapena ma grooves omwe amatha kusunga mabakiteriya.
• Pewani utoto kapena zokutira zomwe zitha kung'ambika
• Gwiritsani ntchito ma lens olimba kuti mupirire kuyeretsedwa kangapo, osapanga chikasu, komanso kuwunikira kwakukulu
• Amagwiritsa ntchito ma LED okhazikika, okhalitsa komanso zamagetsi kuti azigwira ntchito bwino pamatenthedwe apamwamba komanso mufiriji
• Kusindikizidwa ndi zowunikira zowunikira za NSF-zogwirizana ndi IP65 kapena IP66, zosakhala ndi madzi komanso zimalepheretsa kukhazikika kwamkati pansi pamphamvu yothamanga mpaka 1500 psi (splash zone)
• Popeza mbewu zachakudya ndi chakumwa zimatha kugwiritsa ntchito mitundu yofananira yowunikira, kuyimilira kwamafuta akumafakitale a LED kungakhalenso m'malo mwa chiphaso cha NSF, kuphatikiza:
• Zida zotetezedwa ndi IP65 (IEC60598) kapena IP66 (IEC60529)

Ubwino wowunikira chakudya cha LED

Kwa mafakitale a zakudya ndi zakumwa, ma LED opangidwa bwino ali ndi ubwino wambiri kusiyana ndi kuyatsa kwachikhalidwe, monga kusakhalapo kwa galasi kapena zinthu zina zosalimba zomwe zingawononge chakudya, kusintha kuwala, ndi kutentha kochepa m'malo ozizira.Kuchita bwino, kutsika mtengo wokonza, moyo wautali (maola 70,000), mercury yopanda poizoni, kugwiritsa ntchito bwino kwambiri, kusinthika kwakukulu ndi kuwongolera, kugwira ntchito pompopompo, komanso kutentha kwapang'onopang'ono.

Kuwala kwamphamvu kwamphamvu kwamphamvu (SSL) kumapangitsa kuti pakhale zowunikira zosalala, zopepuka, zosindikizidwa, zowala, zapamwamba pazantchito zambiri zamakampani azakudya.Moyo wautali wa LED komanso kukonza pang'ono kungathandize kusintha makampani azakudya ndi zakumwa kukhala mafakitale oyera, obiriwira.
