Nzvimbo yefekitari yezvokudya

Midziyo yekuvhenekesa inoshandiswa muzvidya uye zvinwiwa zvidyarwa ndeyemhando imwechete seyakajairwa maindasitiri nharaunda, kunze kwekunge zvimwe zvigadziriso zvinofanirwa kuitwa pasi pehutsanana uye dzimwe nguva mamiriro ane njodzi.Rudzi rwechigadzirwa chekuvhenekesa chinodiwa uye zviyero zvinoshanda zvinoenderana nenharaunda mune imwe nzvimbo;nzvimbo dzekugadzira chikafu kazhinji dzine nharaunda dzakasiyana pasi pedenga rimwe.

Mafekitari anogona kusanganisira nzvimbo dzakawanda dzakadai sekugadzirisa, kuchengetedza, kugovera, kuchengetwa kwefiriji kana yakaoma, makamuri akachena, mahofisi, mikoridho, horo, zvimbudzi, nezvimwewo.Semuyenzaniso, kuvhenekera mukugadzira chikafunzvimbo dzinowanzofanirwa kumira nemafuta, utsi, guruva, tsvina, chitsinga, mvura, tsvina, uye zvimwe zvinosvibisa mumhepo, pamwe nekugara uchikwesha kwepamusoro-kupfapfaidza uye nehasha yekuchenesa zvinonyungudutsa.

NSF yakamisa maitiro anoenderana nemamiriro edunhu uye nehukuru hwekusangana kwakananga nechikafu.Muyero weNSF wezvigadzirwa zvekuvheneka chikafu nezvinwiwa, zvinodaidzwa kuti NSF/ANSI Standard 2 (kana NSF 2), inokamura nharaunda yechirimwa kuita marudzi matatu ematunhu: nzvimbo dzisiri dzechikafu, nzvimbo dzekupfachuka, nenzvimbo dzekudya.

Kujekesa kwemwenje pakugadzira chikafu

Sezvizhinji zvekuvhenekesa zvikumbiro, IESNA (North American Lighting Engineering Association) yakaseta mazinga anokurudzirwa emwenje kune akasiyana siyana ekugadzira chikafu.Semuyenzaniso, IESNA inokurudzira kuti nzvimbo yekuongorora chikafu ive nenzvimbo yekuvhenekera ye30 kusvika 1000 fc, nzvimbo yekuisa mavara ye150 fc, uye imba yekuchengetera, yekufambisa, yekurongedza, uye yekugezera ye30 fc.

Nekudaro, sezvo kuchengetedzeka kwechikafu kuchienderanawo nemwenje wakanaka, Dhipatimendi rekurima reUS rinoda mwero wakakwana wemwenje muChikamu 416.2(c) cheChikafu Chekuchengetedza uye Inspection Service Manual.Tafura 2 inonyora iyo USDA yekuvhenekesa zvinodiwa munzvimbo dzakasarudzwa dzekugadzira chikafu.

Kubereka kwakanaka kwemavara kwakakosha pakuongorora chaiko uye kugadzwa kwemavara ezvikafu, kunyanya nyama.Dhipatimendi rekurima reUS rinoda CRI yemakumi manomwe yenzvimbo dzekugadzira chikafu, asi CRI ye85 yenzvimbo dzekuongorora chikafu.

Pamusoro pezvo, ese ari maviri FDA neUSDA vakagadzira mafotometric maratidziro ekugovera yakatwasuka yekuvhenekesa.Kuvheneka kwepamusoro kunofanirwa kuyera 25% kusvika 50% yemwenje wakachinjika uye hapafanirwe kuve nemimvuri panokwanisika kukanganisa nzvimbo dzechirimwa dzakakomba.

Food Processing Lighting ramangwana:

• Tichifunga nezvehutsanana, chengetedzo, kwezvakatipoteredza uye kupenya zvinodiwa zveindasitiri yechikafu yemidziyo yekuvhenekesa, maindasitiri emagetsi ekugadzira magetsi e LED anofanirwa kusangana nezvinotevera zvakakosha dhizaini zvinhu:
• Shandisa zvisina muchetura, zvinodzivirira corrosion uye zvisingaremekedzi zvinhu zvakaita se polycarbonate plastic.
• Dzivisa kushandisa girazi kana zvichibvira
• Gadzira nzvimbo yekunze yakatsetseka, isina mvura isina maburi, maburi kana mikoto inogona kuchengetedza bhakitiriya.
• Dzivisa pendi kana nzvimbo yekuputira iyo inogona kubvarura
• Shandisa yakaoma lens zvinhu kutsungirira kucheneswa kwakawanda, pasina kutsvuka, uye yakafara uye kunyange kupenya
• Inoshandisa inobudirira, inogara kwenguva refu LEDs uye zvemagetsi kushanda zvakanaka mukupisa kwakanyanya uye firiji
• Yakavharwa neNSF-inoenderana neIP65 kana IP66 zvigadziriso zvemwenje, ichiri isina mvura uye inodzivirira mukati me condensation pasi pekumanikidzwa kwakanyanya kukwira kusvika ku1500 psi (splash zone)
• Sezvo zvidyarwa nezvinwiwa zvidyarwa zvichigona kushandisa akawanda emhando dzakafanana dzekuvhenekesa, kumira maindasitiri ekuvhenekesa LED zvigadzirwa zvinogona zvakare kuve imwe nzira kune NSF certification, kusanganisira:
• Zvishandiso zvine IP65 (IEC60598) kana IP66 (IEC60529) mwero wekudzivirira

LED chiedza chiedza zvakanakira

Kune indasitiri yechikafu nechinwiwa, ma LED akanyatsogadzirwa ane zvakawanda zvakanakira pane mazhinji echinyakare mwenje, sekushaikwa kwegirazi kana zvimwe zvinhu zvisina kusimba zvinogona kusvibisa chikafu, kuvandudza kubuda kwechiedza, uye kuderera-tembiricha mukuchengetedza kutonhora.Kunyatsoita, mutengo wakaderera wekugadzirisa, hupenyu hurefu (70,000 maawa), isiri-chepfu mercury, kugona kwepamusoro, kuchinjika kwakafara uye kutonga, kuita nekukurumidza uye tembiricha yekushanda.

Kubuda kweanoshanda solid-state lighting (SSL) inoita kuti zvikwanise kuisa yakatsetseka, isingaremi, yakavharwa, yakapenya, yemhando yepamusoro mwenje kune akawanda maindasitiri echikafu maapplication.Hupenyu hurefu hwe LED uye kuchengetedza kwakaderera kunogona kubatsira kushandura indasitiri yechikafu nechinwiwa kuita indasitiri yakachena, yakasvibira.
