-25℃ Kuchengetera zvinhu zvinotonhora tembiricha yakaderera

Mifananidzo yekamuri rekuchengetera zvinhu rine tembiricha yakaderera Tembiricha yekuchengetera zvinhu iri mukamuri rekuchengetera zvinhu rine tembiricha yakaderera inowanzova: -22～-25℃. 

Nekuti zvimwe zvekudya zvakaita se ice cream nezvikafu zvegungwa nezvimwe zvigadzirwa zvenyama zvinoda kuchengetwa patembiricha ye -25°C zvisati zvaora, kana ice cream ikachengetwa pasi pe 25°C, kunhuhwirira kwayo kunonyangarika; Kuravira nekuravira kwacho kwakaipa zvikuru; chinhu chikuru chekuchengetera tembiricha yakaderera ndechekuti: chikafu chinoiswa zvishoma nezvishoma muchengetero inotonhora nguva nenguva. Mushure menguva yakati, tembiricha yekuchengetera inotonhora inosvika -25℃. Hapana chinodiwa chakakosha kwenguva iyi. Tembiricha yekuchengetera ine zvinodiwa zvakasimba, pakati pe -22℃ ~ 25℃, iyi inzvimbo yekuchengetera tembiricha yakaderera.

Nzira yekuverenga kugona kwekuchengetedza zvinhu zvinotonhora

● Kuverenga kwetani yekuchengetera zvinhu zvinotonhora:

1. Matani ekuchengetera zvinhu zvinotonhora = huwandu hwemukati meimba yekuchengetera zvinhu zvinotonhora × huwandu hwekushandiswa kwehuwandu × huremu hwechikafu.

2. Huwandu hwemukati meimba yekuchengetera inotonhora yeimba yekuchengetera inotonhora = kureba kwemukati × upamhi × kukwirira (kubhikiyubhu)

3. Huwandu hwekushandiswa kwehuwandu hwezvinhu zvinotonhorera pakuchengetedza:

500～1000 cubic metres = 0.40

1001～2000 cubic =0.50

2001～10000 cubic metres =0.55

10001～15000 cubic metres = 0.60

● Huremu hwechikafu:

Nyama yakaomeswa nechando = 0.40 matani/cubic

Hove dzakaomeswa nechando = 0.47 matani/cubic

Michero nemiriwo mitsva = 0.23 matani/m3

Aizi yakagadzirwa nemuchina = 0.75 matani/cubic

Mhara yemakwai yakaomeswa nechando = 0.25 matani/cubic

Nyama isina mapfupa kana zvimwe zvinhu = 0.60 matani/cubic

Huku dzakaomeswa dziri mumabhokisi = 0.55 matani/m3

● Nzira yekuverenga huwandu hwenzvimbo yekuchengetera zvinhu inotonhorera:

1. Muindasitiri yekuchengetera zvinhu, fomura yekuverenga huwandu hwepamusoro hwekuchengetera ndeiyi:

Vhoriyamu yezviri mukati inoshanda (m3) = vhoriyamu yezviri mukati yese (m3) X0.9

Huwandu hwepamusoro hwekuchengetera (matani) = huwandu hwese hwemukati (m3)/2.5m3

2. Huwandu hwepamusoro hwekuchengetedza hwenzvimbo inotonhorera yemafoni

Vhoriyamu yezviri mukati inoshanda (m3) = vhoriyamu yezviri mukati yese (m3) X0.9

Huwandu hwepamusoro hwekuchengetera (matani) = huwandu hwese hwemukati (m3) X (0.4-0.6)/2.5m3

0.4-0.6 inotsanangurwa nehukuru uye kuchengetwa kwenzvimbo inotonhorera.

3. Huwandu hwezuva nezuva hwekuchengetedza hunoshandiswa

Kana pasina chimiro chakakosha, huwandu chaihwo hwenzvimbo yekuchengetera zvinhu zuva nezuva hunoverengerwa pa15% kana 30% yehuwandu hwepamusoro hwenzvimbo yekuchengetera zvinhu (matani) (kazhinji 30% inoverengerwa kune avo vari pasi pe100m3).
