Description

Uppfinnare: A Minet Prioritet begard friin den 4 november 1960 (Schweiz) och den december 1960 (Frankrike) For att skilja blandningar av fasta bestandsdelar och vatskor aro hittills i huvudsak tva fOrfaringssatt kanda. Det ena bestar dki, att pressa ut blandningen av det pa for-hand sonderdelade godset medelst pressar. Ett kontinuerligt arbete med detta fdrfaringssatt Or praktiskt taget uteslutet och utbytet br forhallandevis daligt. Inventors: A Minet Priority was released on November 4, 1960 (Switzerland) and December 1960 (France). One consists in pressing out the mixture of the pre-probed goods by means of presses. Continuous work with this method is practically excluded and the exchange should be relatively poor.

Enligt det andra forfaringssattet sattes blandningen, t. ex. sonderdelade frukter eller gronsaker, i snabbt roterande korgar och vatskan slungas darvid ut ur korgarna genom centrifugalkraften. Ett kontinuerligt arbete ir dkvid mojligt om koniska korgar anvandas, men den kontinuerligt verkande centrifugalkraften Or for liten, for att under den till forfogande staende tiden, som blandningen stannar i korgen, uppna ett gott saftutbyte. Den stOrsta nackdelen med dessa kanda roterande slungkorgar bestar dari, att vid oregelbunden fordelning av blandningen vid korgens vagg uppsta utomordentligt starka vibrationer, vilka fororsaka otacka ljud och leda till en snabb avnatning av de belastade maskindelarna. According to the second procedure, the mixture was added, e.g. probed fruits or vegetables, in rapidly rotating baskets and the liquid is thereby thrown out of the baskets by the centrifugal force. Continuous work is possible if conical baskets are used, but the continuously acting centrifugal force is too small to achieve a good juice yield during the time available for the mixture to remain in the basket. The main disadvantage of these known rotating sling baskets is that during irregular distribution of the mixture at the cradle of the basket, extremely strong vibrations arise, which cause unintentional sounds and lead to a rapid nighting of the loaded machine parts.

Uppfinningens mâl Or att undvika alla nackdelar hos de kanda forfaringssatten darigenom, att blandningen accelereras kraftigt flera ganger och slungas °eh pressas mot en fast staende sikt resp. filter, vid vilken de fasta bestandsdelarna hallas kvar, medan vatskan gar igenom. The object of the invention is to avoid all the disadvantages of the known methods in that the mixture is strongly accelerated several times and thrown and pressed against a fixed sieve resp. filter, in which the solids are retained while the liquid passes through.

Medan saledes vid de kanda med masskrafter arbetande forfaringssatten blandningen endast utsattes far den kontinuerligt verkande centrifugalkraften, accelereras blandningen en!. fareliggande uppfinning flera ganger pa nytt och slungas upprepade ganger med stor kraft mot sikten resp. filtret. Darvid uppsta ytterst stora masskrafter, vilka driva vatskan genom siktens eller filtrets oppningar. Samtidigt kan man arbeta med kontinuerlig pasoltning och tiden for behandlingen kan. väljas fritt oberoende av de andra arbetsforloppen. Thus, while in the case of the mass-acting process, the mixture is only subjected to the continuously acting centrifugal force, the mixture is accelerated one! the present invention several times anew and are repeatedly thrown with great force at the sight resp. the filter. Extremely large mass forces arise, which drive the liquid through the openings of the screen or filter. At the same time, you can work with continuous pacing and the time for treatment can. freely chosen regardless of the other work processes.

En hartill lamplig anordning har en. fast sikt eller filter och en mot denna snabbt forbifarda kropp, som.icke har beroring med densamma, med kilartat gentemot sikten eller filtret lutan.de och pa olika avstand frail sikten eller filtret liggande ytdelar anordnade pa sit salt, att de driva blandningen mot sikten eller filtret och samtidigt genom springan mellan kroppen och sikten transportera den i riktning vinkelratt mot kroppens r8relseriktfling. A suitable lamp has one. fixed sieve or filter and a body which does not pass over it rapidly, which has no contact therewith, with wedges opposite the sieve or filter lutan.de and at different distances from the sieve or filter lying surface parts arranged on its salt, that they drive the mixture towards the sieve or the filter and at the same time through the gap between the body and the screen transport it in a direction perpendicular to the direction of movement of the body.

Med hanvisning till ritningen beskrives i det foljande ett utfdringsexempel pa anordningen en!. uppfinningen far utforande av forfaringssattet enligt uppfinningen. Referring to the drawing, an exemplary embodiment of the device is described below. the invention is carried out according to the method according to the invention.

Fig. 1 visar ett axialsnitt och fig. 2 ett snitt efter linjeni fig. 1, fig. 3 visar ett annat utforande enligt fig. 1. Anordningen uppvisar ett cylindriskt stativ 1, i vans owe kant en avloppsranna 2 samt en Mat och uppat strackande krage arc utbildade. Pa stativet 1 vilar ett i huvudsak cylindriskt hus 4 med ett avlopp 5 och en flans 6. I flansen 6 Or ett lock 7 med en fyllstuts 8 fastskruvad. Pa undre sidan Or locket forsett med en under fyllstutsen oppen cirkelformad platta 9, vans undre kant 10 Or nagot nedatbojd, medan den Owe med en krage 11 Or infalld i locket 7. Med denna Jigger plattan 9 inifran dikt an mot en cylinclrisk sikt eller ett filter 12. Mellan sikten 12 och husets 4 yttervagg finns ett uppsanalingsrum 13. I en. for stativet 1 som fot avsedd (icke askadliggjord) maskindel med en drivmotor Or en drivaxel 11 lagrad, vilken uppbar medbringartallriken 19 2— — for rotorn till anordningen. Den avtagbara rotorn bestar av en med skartander forsedd skiva 15 och en skalformad del 16, vars mantelyta Jigger mitt f8r sikten. 12, men icke ber5r densamma pa nagot stalle. Fig. 1 shows an axial section and Fig. 2 a section along the line in Fig. 1, Fig. 3 shows another embodiment according to Fig. 1. The device has a cylindrical stand 1, in the upper edge of the vane a drain 2 and a Mat and upwardly extending collar arc trained. On the frame 1 rests a substantially cylindrical housing 4 with a drain 5 and a flange 6. In the flange 6 Or a lid 7 with a filler neck 8 screwed on. On the lower side the lid is provided with a circular plate 9 open under the filler neck, the lower edge 10 of which is slightly bent down, while the Owe with a collar 11 is folded into the lid 7. filter 12. Between the screen 12 and the outer wall of the house 4 there is a storage room 13. In a. for the stand 1 as a foot intended (not damaged) machine part with a drive motor Or a drive shaft 11 mounted, which carried the carrier plate 19 2 - for the rotor to the device. The detachable rotor consists of a disc 15 provided with a cutting tooth and a shell-shaped part 16, the mantle surface of which jigger in the middle of the screen. 12, but does not affect the same in any stable.

Soni visas i fig. 1, ãr mantelytan pa delen 16 pa hela sin hojd forsedd med langs flacka skruvlinjer riktade bett 17, mellan vilka befinna sig sparformade fordjupningar. Oavsett denna uppdelning i upphojda skarande kanter och daremellan liggartde spar hos rotor. aro hela ytdelar hos rotorn upphojda gentemot andra ytdelar, namligen exempelvis i form av de i ritningen antydda kammarna 18. Som framgar ur fig. 2 aro dessa kammar jamt fordelade langs rotorns periferi och ha kilformade ansatser. Ur fig. 1 framgar dessutom, att grupper av de anordnade kammarna 18 aro forskjutna med jarana avstand i rotorns periferi- och axialriktning och anordnade ungefarligen Mugs en fallande skruvlinje. Mellan kammarna 18 kunna speciella fordjupningar vara anbragta, vilka joke aro framstallda i fig. Soni is shown in Fig. 1, where the mantle surface of the part 16 is at its entire height provided with bit 17 directed along flat helical lines, between which there are recess-shaped depressions. Regardless of this division into raised intersecting edges and in between lying grooves in the rotor. the entire surface parts of the rotor are raised relative to other surface parts, namely for example in the form of the cams 18 indicated in the drawing. As can be seen from Fig. 2, these cams are evenly distributed along the periphery of the rotor and have wedge-shaped projections. It can also be seen from Fig. 1 that groups of the arranged chambers 18 are offset by a certain distance in the circumferential and axial direction of the rotor and approximately arrange Mugs a descending helix. Special depressions can be arranged between the cams 18, which jokes are shown in fig.

Vid kanda maskiner med utbytbara roterande verktyg skruvas dessa verktyg pa en axelande, vilket är mycket omstandligt for en husfru. Fig. 3 visar en utforingsform av foremalet for uppfinningen, vid vilken olika rotorer kunna sattas pa utan fastskruvning. Sam-ma delar ha i fig. 3 samma pos.-nr. som i Ovriga fig. Delarna 15 och 16 i rotorn aro forenade med nitar 22, varvid medbringartappar 31 sitta pa de nedre nitandarna. Pa. drivaxeln 14 Sr medbringartallriken 19 fastsatt, vilken har ett antal urtag 23 motsvarande antalet tappar 31. Mellan den sig nedatstrackande mantel. hos rotordelen 16, kragen 3 i stativet 1, som griper under densamma, en radial flans 26 och den cylindriska yttervaggen 27 pa medbringaren 19 aro t. ex. tre kulor 28 inlagda jamt fordelade Over periferin. Manteln hos rotordelen 16 har ett ringspar 29 vid platsen for kulorna 28. Den delarna 4, 7, 8, 12 och 13 omfattande Owe husdelen Sr medelst joke askadliggjorda bajonettfattningar avtagbart forenad med stativet 1 och centrerad mot en ansats 30 pa detsamma. In known machines with replaceable rotary tools, these tools are screwed onto a shaft, which is very cumbersome for a housewife. Fig. 3 shows an embodiment of the object of the invention, in which different rotors can be put on without screwing. The same parts have in Fig. 3 the same pos. No. as in the other Figs. Pa. the drive shaft 14 is attached to the carrier plate 19, which has a number of recesses 23 corresponding to the number of pins 31. Between the downwardly extending jacket. of the rotor part 16, the collar 3 in the frame 1, which engages below it, a radial flange 26 and the cylindrical outer wall 27 on the carrier 19 are e.g. three bullets 28 inlaid jamt distributed Over the periphery. The jacket of the rotor part 16 has a pair of rings 29 at the location of the balls 28. The Owe housing part Sr.

Rotationsrarelsen hos axeln 14 dverfores frau flansarna 24 pa tapparna 21. Kulorna 28 pressas genom centrifugalkraften in i sparet 29 och sakerstalla armed rotordelarna 15 och 16 mot en. avlyftning frail medbringartallriken 19. Delarna aro sa avpassade, att nar maskinen star, kulorna 28 kunna undantrangas mat ur sparet 29 sa langt, att rotordelarna 15 och 16 genom dragning uppat ut an vidare kunna avlyftas. Lika latt kan en annan rotor sattas pa. For att undvika friktionen mellan de roterande kulorna 28 och kragen 3, kunna kulorna 28 aven vara insatta i passande fordjupningar I medbringaren 22. I alla fall aro kulorna genom motsvarande utformning av de omgivande delarna sakrade mot att falla ut vid utbyte av rotorn. F5r utbyte av rotordelarna 15, 16 lyftas delarna 4, 7, 8 och 12 samtidigt med varandra, for att Ora rotorn fritt atkomlig. The rotational movement of the shaft 14 is transmitted from the flanges 24 on the pins 21. The balls 28 are pressed by the centrifugal force into the groove 29 and secure the armed rotor parts 15 and 16 against one another. lifting off the carrier plate 19. The parts are so adapted that when the machine is standing, the balls 28 can be displaced food from the groove 29 so far that the rotor parts 15 and 16 can be lifted outwards by pulling upwards. Just as easily, another rotor can be put on. In order to avoid the friction between the rotating balls 28 and the collar 3, the balls 28 can also be inserted into suitable depressions in the carrier 22. In any case, the balls are prevented from falling out when the rotor is replaced by a corresponding design of the surrounding parts. To replace the rotor parts 15, 16, the parts 4, 7, 8 and 12 are lifted simultaneously with each other, so that the rotor is freely accessible.

Den framstallda anordningen arbetar som foljer: Raa eller kokade frukter eller liknande av fibera.mnen eller dylikt och saft bestaende substanser inmatas uppifran i stutsen 8. De pa rotorns plana yta liggande delarna av dessa substanser rivas pa kant satt genom skartanderna pa rivskivan 15 i fina smadelar, vilka till foljd av centrifugalkraften hos den med exempelvis 5000-15000 r/min roterande skivan 15 slungas radialt utat. The device produced operates as follows: Raw or boiled fruits or the like of fibrous substances or similar and juicy substances are fed from the top of the nozzle 8. The parts of these substances lying on the flat surface of the rotor are torn at the edge through the edges small parts which, due to the centrifugal force of the disc 15 rotating at 5000-15000 rpm, are thrown radially outwards.

Den nedatbockade rundningen. i kanten 10 pa plattan 9 astadkommer nu, att den av minsta smadelar och vatska bestaende utat slungade blandningen ledes nedat fOrbi den Owe kanten pa rivskivan i springan mellan delen 16 och sikten 12. Dar slungas forst — som vid kanda saftcentrifugervid stoten mot sikten en. del av vatskan ut genom de sma oppningarna och porerna i sikten eller filtret 12 in i uppsamlingsrummet 13. Men darpa gripes den pa den stillastaende sikten gentemot motorvridningen aterstaende blandningen i snabb foljd av de latt lutade, kilartat verkande sidorna hos de pa litet avstand frau sikten eller filtret forbiilande kammarna och slungas och pressas med kilverkan slagartat mot sikten, varvid varje gang ytterligare delar av vatskan pressas ut. Samtidigt soliderstyckas de redan kraftigt extraherade klumparna av fasta bestandsdelar av de roterande betten 17. Genom inverkan av de efter skruvlinjer forlagda betten 17 och kammarna 18 transporteras blandningen resp. de extraherade fasta bestandsdelarna av den mellan rotor och sikten. bildade springan standigt neat och komma slutligen ut genom den mellan stativet 1 och huset 4 bildade Oppningen 20 i avloppet 2. The downward curved rounding. in the edge 10 of the plate 9 it is now ensured that the mixture, which consists of the smallest particles and liquid, is led downwards past the Owe edge of the grating disc in the gap between the part 16 and the sieve 12. part of the liquid out through the small openings and pores in the screen or filter 12 into the collection space 13. or the filter bypasses the combs and is thrown and pressed with the wedge action strikingly towards the screen, each time further parts of the liquid are pressed out. At the same time, the already heavily extracted lumps of solid constituents of the rotating bits 17 are solidified by the action of the bits 17 located along helices and the cams 18, the mixture is transported resp. the extracted solids of it between the rotor and the screen. formed the gap constantly neat and finally come out through the opening 20 in the drain 2 formed between the frame 1 and the housing 4.

Rotorn arbetar liknande den i en centrifugalpump och alstrar mom siktringen ett Overtryck, vars storlek bestarnmes av matten pa ringspalten mellan rotor och sikt, speciellt vid utloppssidan fOr draven, och siktens Oppningsforhallande (forhallandet mellan halytan och totalytan). Den kan installas exakt med ringspalten mellan den slata undre, Oppningen 20 overtackande kanten 21 hos delen 16 och innervaggen pa huset 4 och Or storst nSr oppningsforhallandet endast är c:a 1— 2%. Det kan okas till 8%, varefter saval trycket som aven utbytet sjunker. Siktar av metall 0,2 till 0,4 mm tjocka med utat koniskt utvidgade hl av 0,07 till 0,3 mm diameter ha visat sig vara fordelaktiga. Optimal. forhallanden uppnaddes vid saftextrahering ur frukter och gronsaker med oppningar av 0,25 mm. The rotor works similarly to that of a centrifugal pump and produces an overpressure in the sieve ring, the size of which is determined by the mat on the ring gap between the rotor and the sieve, especially at the outlet side for the gears, and the opening opening ratio (the ratio between the tail surface and the total surface). It can be installed exactly with the ring gap between the smooth lower, the opening 20 covering the edge 21 of the part 16 and the inner cradle of the housing 4 and Or largest when the opening ratio is only about 1-2%. It can be increased to 8%, after which the pressure as well as the yield drops. Metal screens 0.2 to 0.4 mm thick with outwardly conically expanded hl of 0.07 to 0.3 mm diameter have been found to be advantageous. Optimal. ratios were obtained by juice extraction from fruits and vegetables with openings of 0.25 mm.

Spaltstorleken mellan rotor och sikt kan foretradesvis variera mellan 0,5 och 3 mm, dvs. nivaskillnaderna Indian de upph8jda och ned- — —3 sfinkta stallena pa rotorn belOpa sig till 2,5 mm, men det ar fiven m5jligt, att storre niva- skillnader kunna giva battre resultat. Alla an- givna forhallanden och dimensioner galla framfor alit vid behandling ay frukter och gronsaker, men kunna vid behandling av bestamda blandningar, t. ex. i tra- pappers- eller den kemiska industrin, andra forutsattningar giva optimala arbetssott. The gap size between rotor and screen can preferably vary between 0.5 and 3 mm, ie. The level differences Indian the raised and lowered spindles on the rotor amount to 2.5 mm, but it is also possible that larger level differences can give better results. All specified ratios and dimensions apply above all in the treatment of fruits and vegetables, but may in the treatment of certain mixtures, e.g. in the tra- paper or chemical industry, other conditions provide optimal workload.

FOrs5k ha visat, att med denna anordning upp till 70% vatska kan extraheras ur ra a frukter. Energiforbrukningen är icke stone an vid kanda anordningar med roterande filterkroppar. Darvid erhaller man en klar salt, och draven fir avsevfirt torrare an vid safteentrifuger med kontinuerlig matning. Research has shown that with this device up to 70% liquid can be extracted from raw fruits. Energy consumption is not the same for kanda devices with rotating filter bodies. In this way a clear salt is obtained, and the drafts are considerably drier than in juice centrifuges with continuous feeding.

Anordningen kan med fordel amen anvandas for homogenisering av mj 51k, ost, figg och dylikt. Nar anordningen anvandes for homogenisering, exempelvis av mjolk, ar det fordelaktigt, att anvanda en pa stutsen 8 pasatt behallare med reglerbart utlopp, for att jute tillfora substansen, som skall homogeniseras, snabbare an den kan ga genom sikten eller filtret 12. The device can advantageously be used for homogenizing mj 51k, cheese, figs and the like. When the device is used for homogenization, for example of milk, it is advantageous to use a container fitted on the nozzle 8 with an adjustable outlet, in order to supply the substance to be homogenized faster than it can pass through the sieve or filter 12.

Anordningen enl. uppfinningen kan Sven ersatta den som »Mixer» kanda anordningen med i en behallare roterande knivar, em i stallet for en sikt eller ett filter 12 en plat-cylinder utan hal insattes. I detta fall bear-betas blandningen i spalten mellan rotorn och platcylindern pa samma satt som ovan beskrivits, da likval vatskan inte kan ga genom cylindern, kommer den langtgetende homogeniserade blandningen alit efter utgangsmaterialet ut i en mer eller mindre tjo&flytande konsistens (pure) yid nedre anden av rotorn i rannan 2. For framstallningpureer, t. ex. The device acc. According to the invention, Sven can replace the one with which the "Mixer" can use the device with rotating knives in a container, and instead of a screen or a filter 12 a flat cylinder without a slide is inserted. In this case, the mixture is processed in the gap between the rotor and the plate cylinder in the same way as described above, since even if the liquid cannot pass through the cylinder, the long-acting homogenized mixture will, after the starting material, come out in a more or less liquid consistency. spirit of the rotor in rannan 2. For production purees, e.g.

I Sr gronsakssoppor, fruktkompotter eller dylikt, behover darvid i motsats till kanda mixers inget vatten tillsattas de raa frukterna eller gronsakerna. In vegetable soups, fruit compotes or the like, in contrast to kanda mixers, no water is needed to add the raw fruits or vegetables.

Utfiires rotorn med mindre diameter och utformas dess ovre yta som malskiva, och pasattes vidare ett passande lock 7 med inlopp i centrum och med malande motskiva, sa kan anordningen anvandas som kvarn, I. ex. i hushallet som kaffekvarn. If the rotor is made of smaller diameter and its upper surface is designed as a grinding wheel, and a suitable lid 7 is further fitted with an inlet in the center and with a grinding counter plate, then the device can be used as a mill, I. in the house as a coffee grinder.

Slutligen Sr det mojligt, for behandling av olikartade substanser, att byta ut sikten eller filtret 12 och/eller rotorn och eventuellt amen rotorns varvtal. I det i fig. 1 och 3 framstallda utforandet kan anordningen aven anvandas att sattas pa en forefintlig med motor forsedd koksmaskin, varvid en lamplig koppling for drivning ay axeln 14 eller Sven for tallriken 19 kan vara anbringad pa den forefintliga maskinen. Diametern pa rotorn och filtret kan latt anpassas till den till fOrfogande sta.- ende drivkraften. Finally, for the treatment of various substances, it is possible to replace the screen or filter 12 and / or the rotor and possibly the rotor speed. In the embodiment shown in Figs. 1 and 3, the device can also be used to be mounted on an existing motorized cooking machine, whereby a suitable coupling for driving on the shaft 14 or Sven for the plate 19 can be mounted on the existing machine. The diameter of the rotor and the filter can be easily adapted to the driving force available.
