Description

Maskin for bakning av flatbrød.
Foreliggende oppfinnelse angår en maskin for bakning av flatbrød, og spesi-elt potetflatbrød.
Flatbrøddeig som inneholder potet-masse er dårlig egnet for maskinell bakning på grunn av at deigen får en kleberig-het som gjør kjevlingen vanskelig. Deigen må derfor være godt strødd med mel, og strøingen må danne et jevnt dekke. Hvis det finnes udekkede flekker vil disse henge seg fast på kjevlet og rive opp deigen. Disse vanskeligheter er årsak til at maskinell bakning av potetflatbrød ikke har ført til noe brukbart resultat, til tross for at produktet er sterkt etterspurt.
Det er tidligere kjent å føre deigen for-bi kjevlevalser på transportbånd som ligger etter hverandre, hvilket imidlertid har den ulempe at melstrøingen på undersiden av deigen blir vanskeliggjort. Denne ulempe er avhjulpet ved maskinen ifølge oppfinnelsen ved å anordne transportbåndene under hverandre og med økende lengde fra toppen og nedover. Deigen som løper av et transportbånd kommer således ned på et tytt transportbånd som kan gis et helt jevnt mellag, og man er sikret mot udekkede flekker og fasthengning på båndet. For overvalsens vedkommende er det ingen vanskelighet med melstrøingen.
Oppfinnelsen er vist på vedføyde teg-ning, som viser et sammensatt oppriss og vertikalsnitt.
Maskinen består av en rekke transportbånd 1 som føres over valser 2 som er lagret i et stativ 3 som dannes av to vinkeljernsbukker, anbragt på hver side av valsene. Transportbåndene har økende lengde ovenfra og nedover, slik at den av-løpende deig fra det ene bånd faller ned på påløpssiden på det underliggende bånd. I stativet er det videre lagret kjevlevalser 4 som samvirker med transportvalsen på avløpsenden for transportbåndet. Transportvalsene er lagret i lagre 5 på undersiden av vinkeljernene og kjevlevalsene er lagret i lagre på oversiden av samme flens. Snittet til høyre på tegningen er lagt like innenfor lagringen.
Transportvalsene ved påløpssiden, og samtlige kjevlevalser er forsynt med mel-trakter 6, resp. 7 som er åpne mot transportbåndene resp. valsene, og strekker seg over hele valselengden. De er forsynt med åpninger som er dekket av klaffer 8 av gummi eller annet hensiktsmessig materi-ale, og som innstilles til å gi den passende smale åpning for utstrømning av mel.
Driften av valsene skjer ved hjelp av kjedetrekk fra en motor med skruehjuls-utveksling 9, og en felles kjede 10. Kjedehj ulene 11 på valseakslene er anbragt på den fri ende av akslene og har avtagende diameter ovenfra og nedover, slik at tran-sporthastigheten øker etterhvert som deigen kjevles ned og får økende lengde. Kje-den løper avvekslende på over- og undersiden av kjedehj ulene hvorved disse får den tilsiktede veksling i omdreiningsret-ningen, og den driver også en valse 12 som er anbragt inne i stativet og som driver et transportbånd 13 som får tilførsel fra en matetrakt 14. Transportbåndet får tilfør-sel av mel på samme måte som valsene 2 og 4, og samvirker med en kjevlevalse 15. Både denne og de øvrige kjevlevalser drives fra den samvirkende transportvalse ved hjelp av tannhjul 16, som er anbragt på den annen ende av akslene.
Deigen som kommer fra trakten 14 ned på det melbestrødde bånd 13 får den første kjevling ved passering av valsen 15 som drysser mel ned på deigen før den kommer i anlegg mot valsen. Fra båndet 13 går deigen ned på det underliggende transportbånd som fører den til neste kjevlevalse, og slik fortsetter behandlingen inntil deigen fra siste transportbånd føres over på et transportbånd 17 som fører deigen til ovnen.
Den gradvis nedkjevling gir en skån-som behandling, og minsker faren for ved-hengning av deigen til valsene, om det skulle finnes små bare flekker i mellemla-get. Nedkjevlingsdybden kan reguleres for hver valse ved å anbringe lagrene stillbare på stativet eksempelvis ved å anordne lagrene forskyvbare på de skråttstilte stativ-ben.
