- Rarraba zafin ajiyar sanyi:
Ana rarraba ajiyar sanyi zuwa nau'i hudu: babban zafin jiki, matsakaici da ƙananan zafin jiki, ƙananan zafin jiki da ƙananan zafin jiki.
Kayayyakin daban-daban suna buƙatar yanayin zafi daban-daban.
A. Ma'ajiyar sanyi mai zafi
Ma'ajiyar sanyi mai zafi shine abin da muke kira ajiyar sanyi sanyi. Rike da zafin jiki yawanci yana kusa da 0 ° C, kuma sanyaya iska tare da mai sanyaya.
B. Matsakaici da ƙananan yanayin sanyi ajiya
Ma'ajiyar sanyi mai matsakaici da ƙananan zafin jiki shine babban wurin ajiyar sanyi mai daskarewa, yawan zafin jiki yana tsakanin -18 ° C, kuma ana amfani dashi galibi don adana nama, kayayyakin ruwa da kayayyaki masu dacewa da wannan yanayin zafin.
C, ajiyar sanyi mara ƙarancin zafi
Ma'ajiyar sanyi mai ƙarancin zafin jiki, wanda kuma aka sani da ajiya mai daskarewa, ajiyar sanyi mai daskarewa, yawanci zazzabin ajiya yana kusan -20 ° C ~ -30 ° C, kuma daskarewar abinci ana kammala shi ta hanyar sanyaya iska ko kayan aikin daskarewa na musamman.
D. Ma'ajiyar sanyi mai ƙarancin zafi
Ma'ajiyar sanyi mai ƙarancin zafi, ≤-30 °C ajiyar sanyi, ana amfani da shi don abinci mai saurin daskarewa da dalilai na musamman kamar gwaje-gwajen masana'antu da jiyya. Idan aka kwatanta da na sama uku, aikace-aikace a kasuwa bukatar su zama dan kadan karami.
2. Ƙididdigar ƙididdiga na ajiya na ajiyar sanyi
Ƙididdige yawan ajiyar sanyi: (ƙididdige shi bisa ga ƙayyadaddun ƙira na ma'ajin sanyi da ma'auni na ƙasa masu dacewa don ajiyar ajiyar sanyi):
Ƙarfin ciki na ɗakin firiji × ma'aunin amfani da ƙara × nauyin naúrar abinci = ton na ajiyar sanyi.
Mataki na farko shine ƙididdige ainihin wurin da ake da shi da kuma adana shi a cikin ajiyar sanyi: sararin ciki na ajiyar sanyi - sararin samaniya da ake buƙatar ajiyewa a cikin ɗakin ajiya, matsayi da kayan aiki na ciki ke ciki, da kuma sararin da ake buƙatar ajiyewa don kewayawar iska;
Mataki na biyu shi ne a gano nauyin abubuwan da za a iya ajiye su a kowace mita kubik na sararin samaniya bisa ga nau'in kayan kiwo, sannan a ninka wannan don samun tan nawa kayayyakin da za a adana a cikin sanyi;
500～1000 cubic = 0.40;
1001～2000 cubic = 0.50;
2001～10000 cubic = 0.55;
10001 ~ 15000 cubic = 0.60.
Lura: Dangane da ƙwarewar mu, ainihin ƙarar da ake amfani da ita ya fi yawan adadin yawan amfanin da aka ayyana ta ma'aunin ƙasa. Misali, ma'aunin mita cubic mita 1000 na yawan amfanin ajiyar sanyi shine 0.4. Idan an sanya shi a kimiyance da inganci, ainihin ƙimar amfani na iya kaiwa 0.5 gabaɗaya. -0.6.
Nauyin nauyin abinci a cikin ma'ajin sanyi mai aiki:
Daskararre nama: 0.40 tons za a iya adana a kowace mita mai siffar sukari;
Daskararre kifi: 0.47 ton a kowace mita mai siffar sukari;
Fresh 'ya'yan itatuwa da kayan lambu: 0.23 tons za a iya adana a kowace cubic mita;
Kankara na inji: 0.75 ton a kowace mita mai siffar sukari;
Daskararre kogon tumaki: 0.25 tons za a iya adana ta kowace mita mai siffar sukari;
Naman da aka zubar: 0.60 ton a kowace mita mai siffar sukari;
