Ukugcina ubushushu obuchanekileyo kwifriji nakwifriji yakho kubalulekile kukhuseleko lokutya, ukusebenza kakuhle kwamandla, kunye nokusebenza kakuhle kwezixhobo. Ii-thermometers zefriji zedijithali zizixhobo ezibalulekileyo zokufezekisa ezi njongo. Ezi zixhobo zibonelela ngokufundwa kobushushu okuchanekileyo nokuthembekileyo, ukuqinisekisa ukuba ukutya kwakho kuhlala kutsha kwaye kukhuselekile. Eli nqaku lihlola iingenelo, ukusebenza, kunye neendlela ezilungileyo zokusebenzisaithemometha yefriji yedijithali.

Intshayelelo kwi-Digital Refrigerator Freezer Thermometers

I-thermometer yefriji yedijithali sisixhobo esenzelwe ukujonga nokubonisa ubushushu bangaphakathi befriji yakho kunye neendawo zefriji. Ngokungafaniyo nee-thermometers ze-analog zemveli, ii-thermometers zedijithali zibonelela ngokuchaneka okuphezulu, ukusebenziseka lula, kunye nezinye izinto ezifana nemisebenzi ye-alamu kunye nokunxibelelana ngaphandle kweengcingo. Ezi zixhobo zinceda ekuqinisekiseni ukuba izixhobo zakho zisebenza ngaphakathi komgangatho wobushushu ocetyiswayo, nto leyo ebalulekileyo ekugcineni umgangatho wokutya kunye nokhuseleko.

Indlela iiThermometers zeFreezer zeDijithali ezisebenza ngayo

Ii-thermometers zefriji zedijithali zisebenzisa ii-sensors ze-elektroniki ukulinganisa ubushushu. Ezi sensors, ezidla ngokuba zii-thermistors, zibona utshintsho lobushushu kwaye ziluguqule lube ziisignali zombane. I-microcontroller engaphakathi kwi-thermometer icubungula ezi signali ize ibonise ubushushu kwisikrini se-LCD.

Izinto eziphambili

1. Izinzwa:Ii-thermistors ezilinganisa ubushushu.
2. Isilawuli esincinci:Icubungula idatha evela kwiisensa.
3. Bonisa:Izikrini ze-LCD ezibonisa ukufundwa kobushushu.
4. Umthombo wamandla:Iibhetri okanye umbane wangaphandle onika amandla isixhobo.

Iimpawu eziPhambili

Ii-thermometers zedijithali zanamhlanje zihlala zineempawu eziphambili:

• Ukurekhoda Ubushushu Obuncinci/Obukhulu:Ilandelela amaqondo obushushu aphezulu naphantsi arekhodiweyo kwixesha elithile.

Iingenelo zokusebenzisaIthemometha yefriji yedijithali

Ukuchaneka kunye nokuchaneka

Ii-thermometer zedijithali zibonelela ngokufundwa okuchanekileyo kakhulu, ngesiqhelo ngaphakathi kobubanzi be-±1°F (±0.5°C). Oku kuchaneka kubalulekile ekugcineni ubushushu obufanelekileyo, obufanele ukuba kwiifriji bube phakathi kwe-35°F kunye ne-38°F (1.7°C ukuya kwi-3.3°C) kwaye kwiifriji bube phakathi kwe-0°F (-18°C) okanye ngaphantsi. Ukubeka iliso elichanekileyo kubushushu kunceda ukuthintela ukonakala kokutya kwaye kuqinisekisa ukuba ukutya kwakho kuhlala kukhuselekile ukutyiwa.

Ukulungela

Izikrini zedijithali kulula ukuzifunda, nto leyo esusa uqikelelo oluhambelana nee-thermometers ze-analog. Iimodeli ezininzi zinezikrini ezinkulu, ezikhanyisiweyo ngasemva ezilula ukuzifunda nokuba ziphantsi kokukhanya. Iimodeli ezingenazingcingo ziphucula ngakumbi ukulula ngokuvumela abasebenzisi ukuba bajonge amaqondo obushushu bekude, zibonelela ngezilumkiso zexesha langempela ukuba amaqondo obushushu atshintsha ngokungalindelekanga.

Ukhuseleko lokutya

Ukubeka iliso elifanelekileyo kubushushu kubalulekile ukuze kukhuseleke ukutya. Ngokutsho kwe-US Food and Drug Administration (FDA), ukugcina ubushushu obufanelekileyo kwifriji nakwifriji yakho kuyacothisa ukukhula kweentsholongwane eziyingozi. Ii-thermometer zedijithali zinceda ukuqinisekisa ukuba izixhobo zakho zigcina ubushushu obufanelekileyo, zinciphisa umngcipheko wezifo ezibangelwa kukutya.

Ukusebenza kakuhle kwamandla

Ukugcina amaqondo obushushu angaguquguqukiyo nako kunokunceda ekusebenziseni kakuhle amandla. Ukuguquguquka kwamaqondo obushushu kunokubangela ukuba i-compressor isebenze nzima, nto leyo eyandisa ukusetyenziswa kwamandla. Ngokusebenzisa i-thermometer yedijithali ukujonga nokugcina amaqondo obushushu ezinzile, ungenza ngcono ukusetyenziswa kwamandla efrijini nakwifriji yakho, nto leyo enokunciphisa iindleko zakho zombane.

Iingcinga zeSayensi kunye neDatha

Ukubaluleka koLawulo loBushushu

I-FDA icebisa ukuba kugcinwe iifriji kumaqondo obushushu angama-40°F (4°C) okanye ngaphantsi kwazo kunye neefriji kumaqondo obushushu angama-0°F (-18°C) ukuqinisekisa ukhuseleko lokutya. Ukuguquguquka kobushushu kunokukhokelela ekonakalisweni kokutya, nto leyo ebeka umngcipheko kwimpilo kwaye ikhokelele ekuchithekeni. Ukubeka iliso ngokuchanekileyo kobushushu ngee-thermometers zedijithali kunokunceda ukugcina la manqanaba acetyiswayo rhoqo.

Impembelelo ekugcinweni kokutya

Uphando olupapashwe kwiJournal of Food Protection lubonisa ukuba amaqondo obushushu angafanelekanga okugcina ukutya ngawona abangela izifo ezibangelwa kukutya. Ukugcina ukutya kubushushu obufanelekileyo kuyacothisa ukukhula kweebhaktheriya ezifana neSalmonella, i-E. coli, kunye neListeria. Ii-thermometer zedijithali zibonelela ngokuchaneka okufunekayo ukuqinisekisa ukuba la maqondo obushushu ayagcinwa, nto leyo ephucula ukhuseleko lokutya.

Ukusetyenziswa kwamandla

Uphononongo olwenziwe liSebe lezaMandla laseMelika (i-DOE) lubonisa ukuba ukugcina amaqondo obushushu efrijini nakwifriji afanelekileyo kunokuchaphazela kakhulu ukusetyenziswa kwamandla. Izixhobo ezisokolayo ukugcina amaqondo obushushu ahambelanayo zisebenzisa amandla amaninzi. Ngokusebenzisa ii-thermometers zedijithali ukujonga nokulungisa amaqondo obushushu, unokuqinisekisa ukuba izixhobo zakho zisebenza kakuhle.
