-25 ℃ Low kutentha ozizira yosungirako

Zithunzi za chipinda chosungiramo kutentha kochepa Kutentha kosungirako kutentha kwa chipinda chosungirako kutentha kumakhala: -22 ~ 25 ℃. 

Chifukwa chakuti zakudya zina monga ayisikilimu ndi zakudya zam'nyanja ndi nyama zina ziyenera kusungidwa kutentha kwa -25 ° C zisanawonongeke, ngati ayisikilimu asungidwa pansi pa 25 ° C, kununkhira kwake kudzatha; Kukoma ndi kukoma ndizoipa kwambiri; mbali ya otsika kutentha yosungirako ndi: chakudya pang`onopang`ono amaikidwa mu ozizira yosungirako nthawi ndi nthawi. Patapita nthawi, kutentha kwa kusungirako kuzizira kumafika -25 ℃. Palibe chofunikira chapadera pa nthawiyi. Kutentha kosungirako kuli ndi zofunika kwambiri, pakati pa -22 ℃ ~ 25 ℃, ichi ndi chosungirako chotsika kutentha.

Njira yowerengera mphamvu yosungira kuzizira

● Kuwerengera matani oziziritsa kusungirako:

1. Cold storage tonnage = voliyumu yamkati ya chipinda chosungirako chozizira × kugwiritsa ntchito voliyumu × kulemera kwa chakudya.

2. Kuchuluka kwa mkati mwa chipinda chozizira chosungirako chozizira = kutalika kwa mkati × m'lifupi × kutalika (cubic)

3. Mphamvu yogwiritsira ntchito posungirako kuzizira:

500 ~ 1000 kiyubiki mita = 0.40

1001 ~ 2000 kiyubiki = 0.50

2001 ~ 10000 kiyubiki mita = 0.55

10001 ~ 15000 kiyubiki mita = 0.60

● Kulemera kwa chakudya:

Nyama yowunda = matani 0.40 pa kiyubiki

Nsomba zozizira = matani 0.47 pa kiyubiki

Zipatso ndi ndiwo zamasamba = 0.23 matani/m3

Aisi wopangidwa ndi makina = 0.75 matani / kiyubiki

Nkhosa zozizira kwambiri = 0.25 matani / kiyubiki

Nyama yopanda mafupa kapena zopangira = 0.60 matani / kiyubiki

Nkhuku zozizira m'mabokosi = 0.55 tons/m3

● Mawerengedwe a njira yosungiramo kuzizira kosungirako kuchuluka:

1. M'makampani osungiramo zinthu, njira yowerengera kuchuluka kosungirako ndi:

Voliyumu yabwino (m3) = voliyumu yonse (m3) X0.9

Kuchuluka kosungirako (matani) = voliyumu yonse yamkati (m3)/2.5m3

2. Zosungirako zenizeni zenizeni zosungirako zozizira zam'manja

Voliyumu yabwino (m3) = voliyumu yonse (m3) X0.9

Kuchuluka kosungirako (matani) = voliyumu yonse yamkati (m3) X (0.4-0.6)/2.5m3

0.4-0.6 imatsimikiziridwa ndi kukula ndi kusungidwa kwa malo ozizira.

3. Kusungidwa kwa tsiku ndi tsiku komwe kumagwiritsidwa ntchito

Ngati palibe dzina lapadera, voliyumu yeniyeni yosungiramo zinthu tsiku ndi tsiku imawerengedwa pa 15% kapena 30% ya voliyumu yayikulu yosungiramo zinthu (matani) (nthawi zambiri 30% imawerengedwa kwa zosakwana 100m3).
