Stanje: rabljeno, Leto izdelave: 1999, številka stroja/vozila: LC652, Steklenica polnilna linija za pivo KRONES – 24.000 BPH ključ v roke konfiguracija Ta popolnoma avtomatizirana linija za ponovno uporabo steklenic je zasnovana za industrijsko polnjenje piva v steklo in je zgrajena okoli Krones Mecafill VK2V monobloka. Sistem vključuje predpranje, inline HTST pasterizacijo, hladno lepljenje etiket ter celovito logistiko z gajbicami. Celota je zasnovana za visokohitrostno proizvodnjo in kakovostno zagotovljen proces od razgajbanja do končne embalaže. Zmogljivost in razpon embalaže Linija dosega kapaciteto 24.000 steklenic na uro pri 0,5 l ter podpira tudi format 0,33 l. Posode so steklene, vsa oprema je optimizirana za zahteve piva in omogoča hitre spremembe formatov med 0,33 l in 0,5 l. Glavni procesi in obseg dobave V srcu sistema je Krones Mecafill VK2V 066-103/KK (1999) polnilni monoblok s 66 polnilnimi ventili in dvojnim zračenjem za zaščito produkta. Monoblok vključuje 60-postajno izpiralno enoto z visokotlačno vodo ter zapiralni agregat z 11 glavami. Sledi Krones Prontomatic 720-18-86-130 (1999) hladnolepilni etiketirni stroj za prednje, zadnje in vratne etikete pri linijski hitrosti. Predpriprava steklenic se izvaja z dvema pralnima strojema: Krones KES-1-1-190/19-80 (1998, nadgradnja 2013) in Robak PBSz za povratno steklo. Termična obdelava poteka prek Fischer (1999) HTST modula z nazivno zmogljivostjo 130 hl/h za 5°C vstop, 72°C/30s (30 PU) in 11°C izstop, povezan na 6.000 l vmesni rezervoar. Sistem pasterizacije obratuje na 3x400 V, 50 Hz in potrebuje čisti suhi komprimirani zrak 6 bar za pogon in krmiljenje. Dodatno so priloženi Fischer ploščni toplotni izmenjevalci EUROPA 40PI in DUBACAL 400P (PS 16 bar, plošče Cmax 780 mm, Cmin 770 mm). Povratni tok steklenic je zagotovljen s Krones manipulacijo gajbic – razgajbanje, gajbanje in stroj za pranje gajbic, vse vključeno v glavni linijski tok. Avtomatizacija in procesna kontrola Nlsdpfxsziyyye Alied HTST sekcija ima avtomatizirano vodenje s spremljanjem ključnih procesnih parametrov za konstantne mikrobiološke rezultate pri visoki hitrosti. Spremlja se temperatura pasterizacije, zadrževalna temperatura, vstopna in izstopna temperatura, tlak in pretok med pasterizacijo, količina pasterizacijskih enot (PU), nivo vmesnega rezervoarja in tlak polnjenja po rezervoarju. Delovanje je lahko ročno ali avtomatsko, z varnostnimi avtomatskimi regulacijami. Električna specifikacija je 3x400 V, 50 Hz. Linija je prilagodljiva za hitre spremembe med 0,33 l in 0,5 l steklenicami. Pretok linije in integracija Za neprekinjeno in usklajeno delovanje linija povezuje razgajbanje in pralnike steklenic, spajalne/filling/zapiralne monobloke, nato Fischer HTST modul (med polnjenjem in etiketiranjem za mikrobiološko stabilnost). Etiketirka Krones Prontomatic ima več postaj za hladno lepljenje (prednja, zadnja, vratna etiketa). Pralna postaja in manipulacija gajbic tvorita povratni cikel, s sinhroniziranimi hitrostmi in akumulacijo za 24.000 BPH zmogljivost.
