l0 l5 20 25 30 35 40 448 668 2 inledningsskedet av skalningsförloppet och relativt sett mindre tillgänglig volym för produkterna vid skalningsförloppets slutskede. l0 l5 20 25 30 35 40 448 668 2 the initial stage of the peeling process and relatively less available volume for the products at the final stage of the peeling process.
Vid en lämplig utföringsform av skalaren enligt uppfinningen ästadkommes den från inmatningsänden mot utmatningsänden av kammaren minskande storleken av transportutrymmet genom att transportskruvens gänga har frän inmatningsänden mot utmatningsänden avtagande stigning.In a suitable embodiment of the scaler according to the invention, the size of the transport space decreasing from the feed end towards the discharge end of the chamber is achieved by the thread of the transport screw decreasing from the feed end towards the discharge end.
En utföringsform av uppfinningen skall i det följande närmare beskrivas under hänvisning till bifogade ritningar. Fig. l visar delvis i axialsektion en skalare enligt uppfinningen. Fig. 2 visar i tvärsektion en i den i fig. l visade skalaren ingående skalningstrumma.An embodiment of the invention will be described in more detail below with reference to the accompanying drawings. Fig. 1 shows partly in axial section a scaler according to the invention. Fig. 2 shows in cross section a scaling drum included in the scaler shown in Fig. 1.
Den på ritningarna visade skalaren är främst avsedd för skalning av rotfrukter.The peeler shown in the drawings is primarily intended for peeling root vegetables.
Skalaren är uppbyggd på ett av ben 2 och längsgående balkar 4 bildat stativ.The scaler is built on a stand formed by legs 2 and longitudinal beams 4.
I stativet är en till sin grundform cylindrisk trumma 6 roterbart upphängd.In the frame, a cylindrical drum 6 rotatable in its basic shape is suspended.
Huvuddelen av trummans 6 mantelyta är bildad av ett antal, tiex tjugo, med trummans geometriska axel parallella valsar 8. Trumman 6 uppvisar vid sin ena ände, vilken bildar trummans inmatningsände, ett çylindriskt inmatnings- parti l0, vilket är avsett att tillföras rotfrukter via en till inmatnings- partiet ansluten inmatningsskål l2. Vid sin motsatta ände, som bildar utmat- ningsänden, uppvisar trumman 6 ett cylindriskt utmatningsparti l4. Inmatnings- partiet l0 och utmatningspartiet l4 är vid sin ytteryta försedda med fast anslutna, ringformiga element l6 respektive l8, i vilka valsarna 8 är roter- bart lagrade medelst axeltappar 20 respektive 22.The main part of the circumferential surface of the drum 6 is formed by a number, tenx twenty, with the geometric axis of the drum parallel rollers 8. The drum 6 has at its one end, which forms the feed end of the drum, a cylindrical feed portion 10, which is intended to be supplied via root vegetables input bowl l2 connected to the input section. At its opposite end, which forms the discharge end, the drum 6 has a cylindrical discharge portion 14. The feed portion 10 and the discharge portion 14 are provided at their outer surface with fixedly connected, annular elements 16 and 18, respectively, in which the rollers 8 are rotatably mounted by means of shaft pins 20 and 22, respectively.
Trumman 6 med de av trummans inmatningsparti lO och utmatningsparti 14 upp- burna valsarna 8 är roterbart upphängd pä en till skalarens stativ roterbart ansluten axel 24. Axelns 24 ändpartier är försedda med var sin remskiva 26 respektive 28, och trumman 6 uppbäres medelst drivremmar 30 respektive 32, vilka löper dels runt remskivorna 26 respektive 28 och dels runt remskivor 34 och 36, vilka omsluter trummans 6 inmatningsparti l0 respektive utmatnings- parti l4. Den ände av axeln 24, vid vilken remskivan 28 är anordnad, är via en växel 38 ansluten till en drivmotor 40. Såväl upphängning som drivning av trummans 6 sker således medelst axeln 24.The drum 6 with the rollers 8 supported by the feed portion 10 and discharge portion 14 of the drum is rotatably suspended on a shaft 24 rotatably connected to the stand of the scaler and the shaft portions 24 of the shaft are each provided with pulleys 26 and 28, respectively, and the drum 6 is supported by drive belts 30 and 28, respectively. 32, which run partly around the pulleys 26 and 28, respectively, and partly around pulleys 34 and 36, which enclose the feed portion 10 and the discharge portion 14 of the drum 6, respectively. The end of the shaft 24, at which the pulley 28 is arranged, is connected via a gear 38 to a drive motor 40. Both suspension and drive of the drum 6 thus takes place by means of the shaft 24.
Valsarna 8 är separat roterbara medelst en frän drivanordningen för trumman skild drivanordning, bestående av en drivmotor 42, som via en växel 44 och' en remskiva 46 medelst drivremmar 48 är ansluten till remskivor 50 på valsarnas 8 axeltappar 20. 15 20 25 30 35 40 3 448 668 Det inre av trumman 6 bildar en kammare, till vilken är ansluten en skruv- transportör, innefattande en i kammaren roterbart anordnad transportskruv, vilken består av en axel 54 och en gänga 56 samt en till axeln 54 via en växel 58 ansluten drivmotor 60. Vid sin rotation transporterar transport- skruven 52 rotfrukterna genom trumman 6 från inmatningspartiet l0 till ut- matningspartiet l2. Under denna transport skalas rotfrukterna genom ingrepp med de roterande valsarna 8, vilka är försedda med en ytbeläggning av slipande korn av t ex karborundum. Under transporten genom skalaren avlägsnas i allmänhet mellan 30 och 35 % av produktens volym. Genom att skalaren upp- visar tre av varandra oberoende rörelsefunktioner, nämligen trummans rotation, transportskruvens rotation och valsarnas rotation, erhålles en effektiv skalning av rotfrukterna.The rollers 8 are rotatable separately by means of a drive device separate from the drive device for the drum, consisting of a drive motor 42, which is connected via a gear 44 and a pulley 46 by means of drive belts 48 to pulleys 50 on the shaft pins 20 of the rollers 8. The interior of the drum 6 forms a chamber, to which a screw conveyor is connected, comprising a transport screw rotatably arranged in the chamber, which consists of a shaft 54 and a thread 56 and a drive motor connected to the shaft 54 via a gear 58 60. During its rotation, the transport screw 52 transports the root vegetables through the drum 6 from the feed portion 10 to the discharge portion 12. During this transport, the root vegetables are peeled by engaging the rotating rollers 8, which are provided with a surface coating of abrasive grains of, for example, carborundum. During transport through the scaler, between 30 and 35% of the product's volume is generally removed. Because the peeler has three mutually independent movement functions, namely the rotation of the drum, the rotation of the transport screw and the rotation of the rollers, an efficient peeling of the root vegetables is obtained.
I enlighet med uppfinningen är transportskruvens 52 gänga 56 utformad med en stigning, som avtager i riktning från inmatningspartiet l0 mot utmatnings- partiet l4, dvs i transportskruvens 52 transportriktning. Härigenom erhålles en ytterligare förbättring av skalarens effektivitet bäde med avseende på skalningsresultatet och kapaciteten. I det visade utföringsexemplet minskar gängans stigning 56 i sådan grad, att stigningens storlek vid utmatnings- partiet l4 utgör omkring 75% av stigningen vid inmatningspartiet 10. Sålunda är den för rotfrukterna tillgängliga volymen mellan två varv av gängan omkring dubbelt så stor vid inmatningspartiet 10 av trumman som vid utmat- ningspartiet l4 därav, vilket medför att produkterna vid trummans utmatnings- parti har mindre utrymme till sitt förfogande och är tätare sammanpressade än vid trummans inmatningsparti trots att rotfrukternas totala volym genom skalningsförloppet reduceras med 30-35%. Detta medför att rotfrukterna i inledningsskedet av skalningen är mera lättrörliga i trumman, vilket är viktigt för att rotfrukterna skall skalas jämnt, medan rotfrukterna genom gängans 56 efter hand minskande stigning successivt kraftigare anpressas mot skalningsvalsarna 8 i och för ästadkommande av en effektiv skalning.In accordance with the invention, the thread 56 of the conveying screw 52 is formed with a pitch which decreases in the direction from the feed portion 10 towards the discharge portion 14, i.e. in the conveying direction of the conveying screw 52. This results in a further improvement of the scaler's efficiency both in terms of scaling result and capacity. In the embodiment shown, the pitch 56 of the thread decreases to such an extent that the size of the pitch at the discharge portion 14 is about 75% of the pitch at the feed portion 10. Thus, the volume available for the root vegetables between two turns of the thread is about twice as large at the feed portion 10 of the drum as at the discharge portion 14 thereof, which means that the products at the discharge portion of the drum have less space at their disposal and are more tightly compressed than at the discharge portion of the drum despite the fact that the total volume of root vegetables is reduced by 30-35%. This means that the root vegetables in the initial stage of peeling are more mobile in the drum, which is important for the root vegetables to be peeled evenly, while the root vegetables through the gradually decreasing pitch of the thread 56 are successively pressed harder against the peeling rollers 8 to achieve effective peeling.
Genom gängans minskande stigning kommer rotfrukternas uppehällstid vid ett visst varvtal hos transportskruven att förlängas, vilket förbättrar skal- ningseffekten. Vid en skalare enligt uppfinningen erhålles i enlighet härmed både förbättrat skalningsresultat och ökad kapacitet hos skalaren.Due to the decreasing pitch of the thread, the residence time of the root vegetables at a certain speed of the transport screw will be extended, which improves the peeling effect. In a scaler according to the invention, in accordance with this, both improved scaling results and increased capacity of the scaler are obtained.
Det är vid skalaren enligt uppfinningen möjligt att åstadkomma den önskade reduktionen av det för rotfrukterna tillgängliga utrymmet pâ annat sätt än genom minskning av stigningen hos transportskruvens gänga. T ex kan gängans väggar tillta i tjocklek från inmatningspartiet mot utmatningspartiet av trumman eller kan trummans tvärsektion utformas så att den avtager i riktningWith the scaler according to the invention, it is possible to achieve the desired reduction of the space available for the root vegetables in other ways than by reducing the pitch of the thread of the transport screw. For example, the walls of the thread may increase in thickness from the feed portion towards the discharge portion of the drum or the cross section of the drum may be designed so that it decreases in the direction
