Heat exchangers yeindasitiri yechikafu
Ndezvipi zvinopisa kupisa zvinoshandiswa muindasitiri yezvekudya?
A: Mabatirwo ekupisa eindasitiri yechikafu (inozivikanwawo sehutsanana kupisa exchangers) michina yekutsinhanisa kupisa yakanyatsogadzirirwa mamiriro ekugadzirisa chikafu. Basa ravo guru nderekuwana kufambiswa kwekushisa kwakanaka pakati pezvekudya uye nhepfenyuro yekupisa (seutsi nemvura inotonhorera) uku vachinyatsoona hutsanana hwechikafu uye kuchengetedzeka.Musiyano wayo mukuru kubva kune zvakajairwa mumaindasitiri ekupisa kupisa uri pakuti inonamatira kune chikafu-magiredhi egiredhi mune zvese kubva pakusarudzwa kwezvinhu uye dhizaini yekugadzira kusvika kumagadzirirwo ekugadzira. Semuyenzaniso, zvidimbu zvinosangana nezvinhu zvinonyanya kugadzirwa nechikafu-zvinhu zvegiredhi zvakaita se316L simbi isina simbi, uye pamusoro pacho panoitwa electrolytic polishing treatment (roughness Ra<=0.8μm), kubvisa chero makona akafa asina utsanana.Inoenderana nepasi rose uye mudzimba chikafu chekuchengetedza chikafu sezvinodiwa seFDA, 60, EH 6, EH 9{0}60 GB Mhando dzakajairwa dzinosanganisira kuchinjisa kupisa kweplate, goko uye chubhu yekupisa yekutsinhanisa, yakaraswa ndiro yekutsinhanisa, uye yakafara-chiteshi chenji yekutsinhanisa kupisa, inokodzera chikafu chemvura inopisa kupisa mamiriro ane dhizaini yekumanikidza isingadariki 1.2MPa uye tembiricha yekugadzira isingadariki 200 degree.
Ndezvipi zvakakosha zvechigadzirwa zvezvinopisa zvinoshandiswa muindasitiri yechikafu?
Kunyanya hutsanana:Maparts akasangana nezvinhu anogadzirwa necorrosion-resistant uye asiri{1}}zvinhu zvine muchetura zvakaita se316L stainless steel, uye seal anogadzirwa nechikafu{3}}grade elastomers (seEPDM nesilicone), anozadzikisa hutsanana pakudya{4}}grade rubber gaskets.1. Chimiro chakagadzirwa chisina makona akafa uye machanera anoyerera ari mutsetse, achitsigira mu-kucheneswa kwemitsetse (CIP) uye mu-line sterilization (SIP). Mimwe michina inogona kuwana 121℃steam sterilization, ine yekuchenesa yekuvhara chiyero che100%, ichivharira nemazvo kukura kwema microorganisms uye zvinhu zvakasara.
Kunyanya kupisa kupisa kushanda zvakanaka:Inotora counter{{0}yezvino kupisa kupisa uye corrugated plate kuti iwedzere mhirizhonga, zvichiita kuti kupisa kwakanyanya kunaka. Semuyenzaniso, kuchinjisa kupisa kunokwana kwe plate heat exchanger haisi pasi pe 2326 W/(m²·K), inova 3-5 times iyo yechinyakare shell uye chubhu heat exchanger. Mimwe midziyo inokwanisa kudzoreredza kupisa, iyo inogona kushandisa kupisa kwemafuta ekudziya kwepamusoro kufanopisa zvinhu zvinotonhora, zvichideredza kushandiswa kwesimba zvakanyanya.
A: Basa repakati nderekuwana chaiyo calorie control uchichinjira kune yakakosha kugadzirisa zvinodiwa zvekudya. Mabasa chaiwo anosanganisira:
01
1. Basic kupisa kupisa basa
kupisa kana kutonhora zvinhu, sekutonhodza muto uchangobva kusvinwa kubva 30-40 dhigirii kusvika 5-10 dhigirii kuti inhibit oxidation, kupisa manyuchi kusvika 60-70 dhigirii kuvandudza dilution kunyatsoita, uye kutonhodza yakanatswa inodyika mafuta kusvika kukamuri tembiricha kuitira kuchengetedza nyore.
02
2.Sterilization uye kuchengetedza basa
Inogona kufananidzwa nemaitiro ekudya sterilization kuti uwane pasteurization (semuenzaniso, mukaka pa72℃/15 seconds) uye ultra{{4}high tembiricha instantaneous sterilization (UHT, eg, mukaka pa135-150℃).Kunyange ichiuraya mabhakitiriya anokuvadza, zvinoderedza kurasikirwa kwezvinovaka muviri uye kuparadzwa kwezvinovaka muviri. Semuyenzaniso, ultra-high tembiricha kurapwa soy sauce pa140 dhigirii kwemasekonzi matatu kunogona kuderedza kurasikirwa kweamino acid nitrogen ne60%.

3. Concentration uye kunaka kuvandudza basa:
Iyo evaporation system inoshandiswa kuisa pfungwa pazvinhu. Munguva yekugadziriswa kwejusi, kupisa kwakadzikama kwemhepo kunodzorerwa kuburikidza nekutsinhanisa kwekushisa, izvo zvinoderedza kushandiswa kwesimba paunenge uchiona kuti vhitamini C yekuchengetedza yakawanda inopfuura 90%. Nokuenzanisa maitiro echinyakare ekuchembera, akadai sevhiniga kuchembera, nguva yekukwegura inogona kupfupiswa kusvika kumazuva makumi matatu, ichichengetedza pamusoro pe85% yezvinonhuhwira.

4. Masevha{1}}ekuchengetedza magetsi nekuchengetedza mabasa
Iyo tekinoroji yekudzoreredza tekinoroji inobata kupisa kwemvura inobuda kuti itange kupisa chikafu, zvakanyanya kuderedza kushandiswa kwesimba; Iyo mbiri chubhu sheet uye yakavharwa yakavharwa dhizaini inodzivirira kuyambuka-kusvibiswa pakati pezvinhu uye kupisa kwemukati, kuve nechokwadi cheutsanana hwechikafu uye kuchengetedzeka. Iyo mbiri-tube sheet uye yakavharwa yakavharwa dhizaini inodzivirira kuyambuka-kusvibiswa pakati pemidziyo nezvinotamisa kupisa, kuve nechokwadi cheutsanana hwechikafu uye kuchengeteka.Mamwe mamodheru akangwara ane yambiro pamberi pemazuva matatu, anoburitsa yambiro pamberi pemazuva matatu. kuderedza chiyero chenguva isina kurongwa.
