Description

Die Erfindung betrifft eine Saftzentrifuge mit einem Zuführstutzen und einem Rotor, der zur Feinzerkleinerung von Früchten und Gemüsen eingerichtet ist und an der Peripherie einen sich nach oben ausweitenden Siebmantel hat, welcher zugleich zur Ausschleuderung des Saftes und zur kontinuierlichen Wegbeförderung des entsafteten Schneidgutes dient.The invention relates to a juice centrifuge with a feed nozzle and a rotor which is used for fine grinding of fruits and vegetables and at the periphery one that widens upwards Has sieve jacket, which at the same time for ejection of the juice and for continuous removal of the juiced food to be cut.

Derartige Saftzentrifugen sind in verschiedenen Ausführungen bekanntgeworden. Wegen der zur Erzielung der kontinuierlichen Wegbeförderung des entsafteten Schneidgutes notwendigen Ausweitung des Siebmantels ist es, wie eingehende Versuche gezeigt haben, bei diesen Saftzentrifugen sehr viel schwieriger, eine gleich gute Saftausbeute zu erzielen wie bei den Saftzentrifugen, deren Rotor einen periodisch zu entleerenden, im wesentlichen zylindrischen Siebmantel hat. Diese Schwierigkeit liegt unter anderem darin begründet, daß die vielen Arten von Früchten und Gemüsen, die zu verarbeiten sind, sich bezüglich Beschaffenheit, wie z. B. der Härte, der Zähigkeit, dem strukturellen Aufbau, außerordentlich stark voneinander unterscheiden. Ferner wurde festgestellt, daß die weitaus größte Saftmenge von jedem Schneidgutteilchen jeweils dann abgegeben wird, wenn dieses unter der Zentrifugalkrafteinwirkung auf dem Siebmantel aufprallt.Such juice centrifuges have become known in various designs. Because of the achievement the continuous transport of the juiced cut product necessary expansion of the As detailed tests have shown, it is much more difficult with these juice centrifuges to to achieve the same good juice yield as with the juice centrifuges, whose rotor is periodic has to be emptied, essentially cylindrical screen jacket. This difficulty lies among other things based on the fact that the many kinds of fruits and vegetables that are to be processed are different in terms of quality, such as B. the hardness, the toughness, the structural design, extraordinary differ greatly from each other. It was also found that by far the largest amount of juice from each Material to be cut is released when it is exposed to centrifugal force on the Sieve shell impacts.

Die Erfindung besteht daher in der gemeinsamen Anwendung mehrerer Maßnahmen, von denen einzelne, für sich allein genommen, bei Saftzentrifugen bereits bekannt sind. Die erfindungsgemäße Saftzentrifuge zeichnet sich dadurch aus, daß der in bekannter Weise einen flachen Boden aufweisende Rotor als weitere Bestandteile eine an sich bekannte, mit diesem Boden einen ersten Ringkanal und mit dem Siebmantel einen ersten Ringspalt bildende Schneiduiid Schleuderscheibe und ferner einen den Zuführstutzen umgebenden, mit dem äußeren Randteil dieser Scheibe einen zweiten Ringkanal und mit dem Siebmantel einen zweiten Ringspalt bildenden Blechring aufweist, wobei die Schneid- und Schleuderscheibe in einer unter dem Innenraum des Zuführstutzens gelegenen Ringzone zum Reiben und zum Schaben eingerichtet ist, damit die abgeriebenen Teilchen durch den ersten Ringkanal und die abgeschabten Teilchen durch den zweiten Ringkanal hindurch unter Zentrifugalkrafteinwirkung gegen den Siebmantel geschleudert werden, wobei alle diese Teilchen an den beiden Ringspalten auf die dort bereits auf dem Siebmantel aufliegenden Teilchen eine Verdrängungswirkung ausüben. The invention therefore consists in the joint application of several measures, of which individual, taken on their own, are already known in juice centrifuges. The juice centrifuge according to the invention is characterized in that the rotor, which in a known manner has a flat bottom as further components a known per se, with this bottom a first ring channel and with the Sieve casing a first annular gap forming a cutting edge centrifugal disk and also a feed nozzle surrounding, with the outer edge part of this disc a second annular channel and with the screen jacket has a second annular gap forming sheet metal ring, wherein the cutting and centrifugal disk in an annular zone located under the interior of the feed nozzle for rubbing and scraping is to allow the abraded particles through the first annular channel and the abraded particles thrown through the second annular channel under the action of centrifugal force against the screen jacket be, with all these particles at the two annular gaps on the ones there already on the sieve shell overlying particles exert a displacement effect.

Bei einer solchen Ausbildung kommt man für alle Früchte- und Gemüsearten ohne Auswechseln von Teilen aus; es müssen alle Schneidgutteilchen, die abgeriebenen und die abgeschabten, durch einen zwischen SaftzentrifugeWith such a training you can get all types of fruit and vegetables without changing parts the end; all of the material to be cut, the rubbed off and the scraped off, must pass through one between Juice centrifuge

Die Verdrängungswirkung, die an den beiden Ringspalten entsteht, sorgt dort für eine Wegbeförderung der Schneidgutteilchen auch bei geringer Konizität des Siebmantels.rotating surfaces located first or second annular channel pass through, whereby the centrifugal force is reinforced. The displacement effect that occurs at the two annular gaps is responsible there for a removal of the material to be cut even with a low conicity of the screen jacket.

Claims

The knife attached to the upper part 43 has the task of preventing rotation of the material introduced into the filler neck, which is coaxial with the rotor shaft 41. On a hexagonal part 41 α of the rotor shaft 41, a rotor body 46 sits non-rotatably, to the top of which the bottom 47a of a screen basket 47 is firmly connected, the screen jacket of which is stepped at approximately mid-height, with the two upwardly conically widening screen jacket sections on the inside a very fine-meshed sieve 48 and 49 are provided. A cutting and centrifugal disk 50 of the rotor is detachably attached to an upper threaded extension of the rotor shaft 41 α with the aid of a pyramid-shaped cap nut 51, with a distance a between the screen basket bottom and the disk 50 remaining thanks to an intermediate ring 52. A sheet metal ring 53 is inextricably connected to the disc 50 by a ring of studs 54, the flat ring part 53 a at a distance b above the outer, flat part of the cutting and slinging disc 50 that is smooth at the top and bottom. Thus, an annular part 55 is formed between the parts 50 a, 53 a and an annular channel 56 is formed between the parts 50 a, 47 a. Between the outer edge of the cutting and centrifugal disk 50 and the sieve 48 surrounding it there is a gap 57, the width c of which is approximately the same as the width a of the annular channel 56. The same is between the outer edge of the sheet metal ring 53 and the sieve 48 an annular gap 62 is present, the width d of which is approximately the same as the width b of the annular channel 55. The inner part of the cutting and centrifugal disk 50 located under the usable space of the hopper 43 & has rows of teeth 58 located on radii, which run in the direction of travel of the disc are inclined forward and upward and are each located above a passage opening 59, such that the disc 50 is suitable for both rubbing and scraping. In the area of the serrated lower edge, which is provided with an annular groove 60, of the filler neck 43 b, which is coaxial to the rotor, the disk 50 has two concentric rims of teeth 61 bent out by 90 ° and extending in the circumferential direction, the path of which, viewed in the radial direction, is the serrations and serrated gaps the inside and outside of the annular groove 60. Jagged wreaths overlap. Certain of these additional cutting teeth 61 run around in the annular groove 60, the others run along the inner surface of the filler neck 43 b. The additional teeth are used, for example, to divide fibers into short pieces. Such fibers are exposed on certain types of material to be cut, such as rhubarb, and in particular would clog the passage between the disc 50 and the lower edge of the filler neck. Similarly clogging z. B. plate-shaped apple peel remains act. These are cut into small pieces by the additional teeth 61. Rubbing means cutting off particles and letting them pass through the openings 59; Abraded particles are ejected through the lower annular channel 56, whereas scraped-off particles are ejected between the disk 50 and the lower edge of the filler neck and through the upper annular channel 55. Thanks to the tight dimensions of the annular gaps 57 and 62 and the small conicity of the sieve 48, a build-up of particles which have hit the sieve 48 occurs at these annular gaps, and these are pushed away by subsequent particles. Whether more the rubbing or more the scraping comes into play depends on the texture, e.g. B. the hardness, the toughness, the structural structure, the respective goods to be processed. It is important that, in cooperation with the additional teeth 61, a wide variety of fruits and vegetables can be perfectly chopped down to the last residue and centrifuged with a very good juice yield while the residues are continuously transported away without using differently designed components depending on the nature of the goods to be processed have to. The inner edge 53 b of the sheet metal ring 53 protrudes upwards and forms a gap 63 with the lower end of the filler neck 43 b. Various changes are conceivable. For example, the disk 50 could be provided with additional scraper ribs. Patent claims:
