Ukugcina izinga lokushisa elifanele esiqandisini sakho kanye nesiqandisi kubalulekile ekuphepheni kokudla, ukonga kwamandla, kanye nokusebenza kukagesi kukonke. Amathemometha efriji yesiqandisi edijithali angamathuluzi ayigugu okufeza le migomo. Lawa madivayisi anikeza ukufundwa kwezinga lokushisa okunembayo nokuthembekile, okuqinisekisa ukuthi ukudla kwakho kuhlala kukusha futhi kuphephile. Lesi sihloko sihlola izinzuzo, ukusebenza, kanye nemikhuba engcono kakhulu yokusebenzisaI-thermometer yesiqandisi yedijithali.

Isingeniso Sezifudumezi Zesiqandisi Sedijithali

Ithemometha yesiqandisi yedijithali iyisisetshenziswa esiklanyelwe ukuqapha futhi sibonise izinga lokushisa langaphakathi lesiqandisi sakho nezingxenye zesiqandisi. Ngokungafani namathemometha e-analogi endabuko, amathemometha edijithali anikeza ukunemba okuphezulu, ukusebenziseka kalula, kanye nezici ezengeziwe ezifana nemisebenzi ye-alamu nokuxhumeka okungenantambo. Lawa madivayisi asiza ukuqinisekisa ukuthi izinto zakho zikagesi zisebenza ngaphakathi kwamazinga okushisa anconyiwe, okubalulekile ekulondolozeni ikhwalithi yokudla nokuphepha.

Indlela Ama-Thermometers Wefriji Yesiqandisi Sedijithali Asebenza Ngayo

Amathemometha efriji yesiqandisi edijithali asebenzisa izinzwa zikagesi ukukala izinga lokushisa. Lezi zinzwa, ngokuvamile ama-thermistors, zibona ukushintsha kwezinga lokushisa futhi ziziguqule zibe amasignali kagesi. I-microcontroller engaphakathi kwe-thermometer icubungula lezi zimpawu futhi ibonise izinga lokushisa kusikrini se-LCD.

Izingxenye Ezibalulekile

1. Izinzwa:Ama-thermitors akala izinga lokushisa.
2. I-Microcontroller:Icubungula idatha evela kuzinzwa.
3. Bonisa:Izikrini ze-LCD ezibonisa ukufundwa kwezinga lokushisa.
4. Umthombo wamandla:Amabhethri noma amandla angaphandle anika amandla idivayisi.

Izici Ezithuthukile

Amathemometha esimanje edijithali avame ukuza nezici ezithuthukile:

• Ukurekhodwa kwezinga lokushisa elincane/eliphezulu:Ilandelela amazinga okushisa aphezulu naphansi kakhulu aqoshwe esikhathini.

Izinzuzo Zokusebenzisa aI-Thermometer yesiqandisi Sedijithali

Ukunemba Nokunemba

Amathemometha edijithali anikeza ukufundwa okunembe kakhulu, ngokuvamile phakathi kwebanga elingu-±1°F (±0.5°C). Lokhu kunemba kubalulekile ukuze kugcinwe izinga lokushisa elifanele, okufanele eziqandisini libe phakathi kuka-35°F no-38°F (1.7°C kuya ku-3.3°C) kanti iziqandisi kufanele zibe ku-0°F (-18°C) noma ngaphansi. Ukuqapha izinga lokushisa okunembayo kusiza ukuvikela ukonakala kokudla futhi kuqinisekisa ukuthi ukudla kwakho kuhlala kuphephile ukuthi ungadliwa.

Ukunethezeka

Izibonisi zedijithali zifundeka kalula, zisusa ukuqagela okuhlobene namathemometha e-analog. Amamodeli amaningi afaka izikrini ezinkulu, ezikhanyiswe ngemuva okulula ukuzifunda ngisho nasezimeni eziphansi zokukhanya. Amamodeli angenantambo athuthukisa futhi ukusebenziseka ngokuvumela abasebenzisi ukuthi baqaphe amazinga okushisa bekude, banikeze izexwayiso zesikhathi sangempela uma amazinga okushisa eguquguquka ngokungalindelekile.

Ukuphepha Kokudla

Ukuqapha izinga lokushisa ngendlela efanele kubalulekile ukuze kuphephe ukudla. Ngokusho kwe-US Food and Drug Administration (FDA), ukugcina izinga lokushisa elifanele esiqandisini sakho kanye nesiqandisi kubambezela ukukhula kwamagciwane ayingozi. Amathemometha edijithali asiza ekuqinisekiseni ukuthi izinto zakho zikagesi zigcina amazinga okushisa afanele, zinciphisa ingozi yezifo ezitholakala ekudleni.

Ukusebenza Kwamandla

Ukugcina amazinga okushisa angaguquguquki nakho kungaba nomthelela ekusebenzeni kahle kwamandla. Ukushintshashintsha kwezinga lokushisa kungabangela ukuthi i-compressor isebenze kanzima, kwandise ukusetshenziswa kwamandla. Ngokusebenzisa ithemometha yedijithali ukuze uqaphe futhi usimamise amazinga okushisa, ungakwazi ukuthuthukisa ukusetshenziswa kwamandla kwesiqandisi sakho nesiqandisi, okungenzeka wehlise izikweletu zakho zikagesi.

Ukubaluleka Kokulawulwa Kwezinga Lokushisa

I-FDA incoma ukuthi iziqandisi zigcinwe eku-40°F (4°C) noma ngaphansi kwamafriji ku-0°F (-18°C) ukuze kuqinisekiswe ukuphepha kokudla. Ukushintshashintsha kwezinga lokushisa kungaholela ekonakaleni kokudla, okufaka izingozi zempilo futhi kuholele ekumosheni. Ukuqapha izinga lokushisa okunembile ngama-thermometers edijithali kungasiza ukugcina lawa maleveli anconyiwe ngokungaguquki.

Umthelela Ekugcinweni Kokudla

Ucwaningo olwanyatheliswa kuyi-Journal of Food Protection lubonisa ukuthi izinga lokushisa elingafanele lesitoreji yimbangela ehamba phambili yezifo ezitholakala ekudleni. Ukugcina ukudla ezingeni lokushisa elifanele kunciphisa ukukhula kwamagciwane afana ne-Salmonella, E. coli, ne-Listeria. Amathemometha edijithali ahlinzeka ngokunemba okudingekayo ukuze kuqinisekiswe ukuthi lawa mazinga okushisa ayagcinwa, athuthukisa ukuphepha kokudla.

Ukusetshenziswa kwamandla

Ucwaningo olwenziwa uMnyango Wezamandla wase-US (i-DOE) lugqamisa ukuthi ukunakekela isiqandisi esifanele nezinga lokushisa lesiqandisi kungaba nomthelela omkhulu ekusetshenzisweni kwamandla. Izinto zikagesi ezilwela ukunakekela izinga lokushisa elingashintshi zisebenzisa amandla engeziwe. Ngokusebenzisa amathemometha edijithali ukuze ugade futhi ulungise amazinga okushisa, ungaqinisekisa ukuthi izinto zakho zikagesi zisebenza kahle.

Ukukhetha I-Thermometer Yesiqandisi Esifanele Yedijithali

Ukucatshangelwa

Lapho ukhetha i-thermometer yesiqandisi yedijithali, cabangela izici ezilandelayo:

• Ukunemba:Qinisekisa ukuthi idivayisi inikezela ngokunemba okuphezulu, phakathi kokungu-±1°F (±0.5°C).
• Ukuqina:Bheka amamodeli aqinile futhi akhelwe ukuhlala isikhathi eside.
• Izici:Khetha ithemometha enezici ezihambisana nezidingo zakho, njengemisebenzi ye-alamu, ukuxhumeka okungenantambo, noma izinga lokushisa eliphansi eliphansi/eliphansi.
• Ukusebenzisa kalula:Khetha imodeli enesibonisi esicacile, esifundeka kalula nezilawuli eziqondile.

Ekuphetheni,I-thermometer yesiqandisi yedijithalis angamathuluzi abalulekile okugcina indawo ekahle yokugcina ukudla. Ukunemba kwazo, ukusebenziseka kalula, kanye nezici ezithuthukisiwe zizenza ziphakame kunamathemometha endabuko. Ngokutshala kuthemometha yedijithali yekhwalithi, ungaqinisekisa ukuphepha kokudla, uthuthukise ukusebenza kahle kwamandla, futhi wandise isikhathi sempilo yezinto zakho zikagesi.

Ukuze uthole ulwazi olwengeziwe olugunyaziwe mayelana nezincomo zokuphepha kokudla nezinga lokushisa, vakashela i-FDA'sUkuphepha Kokudlaikhasi kanye ne-DOE'sIsilondolozi samandlaizinsiza.
