Imithombo yokupasteuriza amasi: HTST vs. UHT
- Ukuprosesa kwe-HTST: Yadlulwe ukusuka kumilki eya kushiswa. Ngokufaka umilki kusukela kuma- 72°C ngomzuzu wama-15 , le sistimu iyasebenza ngamaphathogeni amathile okwesibhakabhaka futhi iyakhumbula izinkomo zemilki yokuqala nezinhlobo zamaprothini zemilki yokuqala. Ngokuba izispo ngeyona ziyasinda le mvelo, isiphumo sokugcina kufanele sisebenze ngokuphatha kwesikhathi esingafihli.
- Ukusebenzisa i-UHT: Yadlulwe ukusuka kumilki we-dairy oyisikhwama. Ngokufaka usuku kuma- 137°C–142°C ngomzuzu wama-2 kuya kuma-4 , le sistimu iyafika emkhawulweni wokusebenza komkhawuli, iyagcina kabusha amabakteriya nezispo zokufuna isuku. Isikhathi esincane sokugcina sivimba ukuthi izinkomo zemilki zizihlabe, sivimba ukuthi kubhekwe njengokushiswa kanye nokuvumela ukugcina kwezindawo zokuhlanza.
Amazwi okushiswa kwe-fruit juice nezindawo zokudla
Kungasemthwakathwini we-dairy engenayo isikhulu (pH > 4.6), izi-juice zemithi ziyisikhulu esiphezulu (pH < 4.6). Ngakho-ke, ukushiswa kwe-juice kuyasebenza kakhulu ngokuvimba ukuzimisa amahashi (njengoko pectinesterase) ukungakhathalisi ukuphakanyiswa kwe-juice, ngokufanana nokuthi ubulawuli abanye amasithili nezinkumbulo. Lokhu kudinga ukugcina imizimba yezinkampani 85°C ku-95°C ngemizuzu eyisikhombisa ku-30 , kusukela kumkhakha wemipunga nezinkumbulo zokuphakanyiswa.
I-Plate Pasteurizer vs. I-Tubular Pasteurizer: Yini okufanele ukwenza ukuze ukhethwe indawo eyodwa?
Ngaphambi kokuthi umphumela wakho wokugcina imizimba nezimizuzu zokugcina zihlanganiswe, kufanele ukhethwe isikhombisa sokuchaza isikhathi esifanayo. Kuleli sikhathi, Weishu , sizokwakha izinkampani ezimbili I-Plate Pasteurizers kanti I-Tubular Pasteurizers , ezinye ngokuvamile kuzo izinhlobo zemilayi nezinkinga zokuchaza isikhathi.
Yini okufanele ukwenza ukuze ukhethwe i-Plate Pasteurizer
Iplate pasteurizer iyinkimbinkimbi zokuphatha amaphethi e-stainless steel engezansi yekhafu.
- Kubhekwe kakhulu kuma-: Amadilithi angaphezulu kwe-viscosity, anganakho iziqephu njengoko kuyisibonelo sokuthi umilki wokuphatha okusha, umilki wokuphatha okungamnandi, ne-fruit juices ezibomvu .
- Izinzuzo: Iyathola i-heat transfer coefficients ephambili ngokwesikhathi sokuthi isikhathi sokuphatha esiphambili sisebenza ngokuphambuka kwe-turbulent flow esibonakalayo ngokuphambuka kwe-chevron patterns kule mphakathi. Lokhu kusiza kuzoba noma kubanzi i-heat regeneration ratios (up to 90%+) , apho umilki wokuphatha omubi uphatha umilki wokuphatha wokusha, ukuncima ukusebenza kwemisthi yaseplanti. Ikhafu liyinkimbinkimbi kakhulu, futhi ukukhula kwayo kungakwaziwa ngokufutshane ngokudibanisa amaphethi angaphezulu kule khafu.
- Izindlela zokuphatha: Amaphethi ayinamagap angaphezulu (ngokuvamile 2–5mm). Amadilithi angaphezulu kwe-viscosity noma iziqephu zokuphatha zingasindiswa ngokushesha ngokuphatha kwe-plate pasteurizer, okubangela ukuphamba kwe-pressure futhi ukuphulwa kwezikhathi eziningi ukwenza i-CIP cleaning.
Lapha ufuna ukukhetha i-Tubular Pasteurizer
Ukusebenzisa isikhombisi sokugxila kwezinkampani esihlukene kusuka emva kwezinkampani eziningi zokugxila okanye ukugxila kwezinkampani ngaphakathi kwezinkampani, apho umsebenzi wasebenza ngaphakathi kwemithambo eyingezansi ezingaqondwa ngumkhakha wokugxila / ukugxila.
- Kubhekwe kakhulu kuma-: Ukuproducwa kwe-milk yase-UHT yesikhathi esiphakade, amanjyu ephutha, amakhompyutha, nezinto zokudla zase-dairy zokufana nokufana kwezinkampani zokufana.
- Izinzuzo: Ngoba akukho izindawo zokuhlanganisa okungafanele noma izigasket zangaphakathi eziboniswa ngumsebenzi wasebenza, izipasturayiza zase-tubular zinokusebenzisa izimilo eziningi (ezingaphezu kwe-30–50 bar) nezilwanyana ezinazo iphutha, izihlangothi, noma izinye izilwanyana ezincinci ngaphandle kokuzwa. Ukubeka kwezinkampani zangaphakathi kuyabeka ukungafanele kokufoula kwezinhlobo zokugxila ngaphakathi kwezikhathi esizwele kakhulu zokugxila / ukugxila kwe- UHT , kusivumela umgqa ukusebenza ngqo ngamahora amaningi ngaphambi kokuthi kufuneka kwenziwe i-CIP.
Ukuthi kanjani ukuthi ukugxila kwezinhlobo kuvumela ukuthi isikhathi sokuhlala sibe sesikrini?
Isikhathi sokugcina sibonakalisa kakhulu ngokwemvelo kubudlela be-milk. Uma imililita eyodwa yemilki iphuma kwe-pasteurizer kusheshile kunezinsuku ezi-15 (kuma-HTST) noma imiseko emibili (kuma-UHT), wonke umkhawulo uyaphila kwezinkinga zokuphepha nokufaneleka.
Ukuqondwa kwe-engineering malunga nokubala ubude bokuthiwa kwe-tube
Isikhathi sokugcina akubekiwa ngokusebenzisa isithombe sokuvavanya; kubekiwa ngokusebenzisa indawo yezinkampani zokugcina ephathelene nezinhlobo zokugcina ezihlukene, okuyizindawo zokugcina ezihlukene, okuyi- Holding Tube . Ubude bokuthiwa kubhalwa ngokubeka phakathi kwesivinini esingaphansi (V, ngem³/h) nesivinini sesikhathi sokugcina (A).
Ukuze kubhekwe izinto ezisheshile kakhulu ekhanda lokuqala kwe-tube wokugcina ngokwesivinini esisheshile, abasebenzi base-engineering bafaka isifactor sokuphepha (isifactor sokuvavanya ukuvavanya kwe-velocity). Abasebenzi base-Weishu bakhulisa isikhathi sokugcina ngokubeka ubude obuhle obuphambili (ubude obungaphezu kwe-1:50) ukuze kungabekwe izindawo zokugcina kwe-air, okuzoba kunciphisa ubude bokuthiwa kwe-tube futhi kunciphisa isikhathi sokugcina.
Ukungena kweziflow ngokungafani ngezimpumpu ze-VFD
Ukuze kubhekwe isikhathi sokugcina ngokuphelele, umthelelo wemithambo yomfanekiso kufanele kube phakade. Amalayini we-pasteurization ase-Weishu ayisebenzisa izimpumpu zokuthumela okuphakade noma izimpumpu zokugcina zokusebenza ngokuphelele ezihlanganisiwe ngokuphelele ne- Izimpumpu zokuguqula ifrekhwensi (VFD) ezihlanganisiwe nezimithambo zokubhalwa kwemvelo. Uma isistimu isibonakalisa ukuphupha kwe-pressure noma ukuguqula kwe-viscosity yomfanekiso, i-Siemens PLC iyagwema ngokushesha umthelelo wempumpu ukuze kungavunyelwe ukuthuthuka komfanekiso, ukuvikela ukuthi akukho iprodukti eya ngokungafani kwe-holding loop.
Kungani ukuthuluzwa kwetempurethcha ngokuzenzakalela kuyisisekelo sokuhlela kwe-pasteurization?
Even a minor temperature deviation can ruin a production run. Under-heating results in a failed pasteurization cycle and microbial risks, while over-heating burns dairy proteins and scorches fruit sugars, altering the product's taste and causing rapid equipment fouling.
- Ukuguqula kwetempurethcha ngokuzenzakalela ngokusebenzisa i-PID ngokusebenzisa i-Siemens PLC: Amaphakethi we-integration ase-Weishu ayinikeza amathuluzi Ukusebenza kwe-Siemens S7-1500 PLC kusebenza imithambo yezinkulungwane zokuphakama (Proportional-Integral-Derivative) ngokushesha kakhulu. Kuyilandelwa ngemithambo emibili ye-PT100 yokubala isikhati nempamba yezistim eyodwa ngokuphambuka, lokhu kubona ukuguqula kwesikhati ngokushesha kakhulu. Uma isiphumo sesistim sibuyekeka, i-PLC iyagcina indlela yempamba ngemizuzwana eminingi, ibeka isikhati sokuphatha noma sokuphatha kwe-UHT ngokugcina isikhundla esincinci kakhulu sokuthi ±0.1°C .
- Indima yokuqinisekisa ukuthi kufanele kwenziwe ngokuzenzakalelayo yempamba yokuhambisa umsindo ngokuzenzakalelayo: Iphakanyisiwe ngaphakathi kwezindawo zokuphuma zakwe-holding tube impamba yezintathu izinye Isikhombisa Sokugcina Umthwalo (FDV) . Uma isensor yesikhati ekupheleni kwe-holding tube isibuyekeka ngokulinganayo okungu-0.1°C phansi kokuchazwa kwe-pasteurization, i-PLC ye-Siemens iyadlula ngokushesha impamba yokuhambisa umsindo ngokuzenzakalelayo. Umzimba ongavaliwe ngokuphambuka uyahambiswa ngokushesha away from izilayini zokufaka futhi uyabuyiselwa emzimbeni wokubalansisa umzimba wokwakhiwa ngokuzenzakalelayo ukuze wabuyiselwe. Lokhu kucindeze kuzenzakalelayo kusiza ukuthi umzimba ongavaliwe ngokuphambuka angafike kwezilayini zakho zokufaka ngaphansi.
