Definitions

• the invention relates to a method for producing breastfeeding, according to the preamble of claim 1.
• a method of this type is known (DE-PS 28 53 054 and DE-PS 29 41 802 - D 5585 and D 5783).
• the viscous mass is guided in tubular bodies, which are designed such that, due to a certain excess pressure within the rotating tubular body, the mass is pressed out in droplet form when the openings of the two tubular bodies come to coincide.
• the drops formed in this way then fall down onto a cooling belt, are pressed a little flat due to their own weight and then solidify to the desired, generally lenticular pastille shape.
• the invention is based on the object of proposing a method of the type mentioned at the outset by means of which much smaller pastilles, so-called micropastilles, can be produced without great additional expenditure.
• a method with the features of claim 1 is proposed.
• the previously used manufacturing process based on the Drop formation is based, leave and the individual droplet-like quantities that later harden to the micropastilla are produced by the discontinuous contact of the mass emerging from the openings with a contact surface which inevitably pulls the mass particles out of the openings due to their inherent toughness.
• the metering of the individual mass pieces can be achieved by opening or closing corresponding outlet openings, but also by a corresponding movement of a transport surface, which is moved toward and intermittently moved away from the partial quantities emerging from corresponding openings.
• Conveyor belt or a cooling roller is removed and removed.
• claim 8 provides an advantageous solution to the thread-pulling which occurs in the device according to the invention due to the method used and which occurs in some products ⁇ material parts pull threads as the tube body rotates relative to the conveyor belt, which also moves, but which are detached from the circumference of the tube body by the thread winding roller and are then wound onto the thread winding roller. During their transport, below the thread winding roller, all the thread ends are therefore pulled off, so that the micropastilles which are then subjected to cooling harden after the thread end sinks back to a perfect pastille shape and there are no protruding thread ends on the belt.
• Claim 11 finally outlines a possibility of keeping the mass of the wound threads in the flowable state and then releasing them again to the circumference of the outer rotating tubular body, which inwardly advances the additional, but flowable mass adhering to it into a pocket ⁇ emits rich, in which a vacuum occurs between the inner stationary tube body and the outer rotating tube body through a gap.
• Show it: 1 shows a schematic representation of a possibility for carrying out the method according to the invention for the production of pastilles, in which viscous mass flows down through openings and is taken up by a surface moved underneath,
• FIG. 5 shows a schematic cross section through rotating tubular bodies of a device for the economical implementation of the method of FIGS. 1 to 4 and
• FIG. 6 shows a variant of the device according to FIG. 5.
• FIG. 1 schematically shows a roller (41) rotating in the direction of the arrow (6) about the axis (46), which can be raised intermittently in a manner not shown vertically in the sense of the arrows (47).
• the roller (41) can be moved with its surface (40) into the position (40 ') shown in broken lines, in which this surface (40) reaches very close to a nozzle-shaped outflow opening (44) of a container (42) , which is filled with a liquid, viscous mass (43).
• This mass can be kept in a manner not shown at a certain temperature at which it has such a viscosity that it would flow out slowly and drop by drop due to gravity from the outflow opening (44).
• the roller (41) can be designed as a cooling roller, so that the mass particles entrained by the surface (40) and adhering to the surface cool and solidify when moving on the surface of the roller (41). They can be removed in the direction of arrow (48) using a scraper (45).
• FIG. 2 shows that under the influence of gravity, a partial mass (23) corresponding approximately to the tip of a drop forms at the outlet opening (44).
• the surface (40) which moves from left to right in the direction of the arrow (6), is then raised into the position indicated by dashed lines in FIG. 2, so that it then moves a little further down leaked part of the tip of the partial mass (23) comes into contact. Due to its inherent toughness, the partial mass adheres to the surface (40) and can move vertically downwards as well as in the direction of the arrow (6) when the surface (40) moves away, both in the direction of the arrows (47) can take place, pulled out of the openings, to the extent that, according to 4-
• Fig. 4 which first forms in strand form (25 ') partial mass to form a viscous, flowable pile (25), the connection to the overlying and from the opening (44) flowing viscous mass breaks off.
• the torn-off tip which is still at the pile (25), sinks back into the pile due to the fluidity still present and, under the influence of the surface forces, forms an approximately lenticular shape in which the mass, as shown in FIG. 1 indicated, solidified to the pastille shape on the surface (40).
• an outer tubular body (1) is rotatable and concentrically guided on an inner, stationary tubular body (2), which is also cylindrical and has a bore (11) in its interior for supplying the mass to be processed and two bores gene (10) for supplying a heat exchange medium. All three bores (10 and 11) are provided in an unshown manner on one end face of the inner tubular body (2) with an external connection and are closed in the area of the other end face.
• the bores (10) can also be connected to one another there.
• the inner tubular body (2) has a plurality of bores (12) which run downwards perpendicularly to the central axis (17) and which open into a space (13) which extends longitudinally in the tubular body (2) and has an extension downward.
• a nozzle strip (14) is inserted, which is held out by its lateral guide lugs (18).
• This strip (14) is inserted from one end into its corresponding guide (19). It has a series of openings (4) leading downwards, which cyclically overlap with openings (3) that evenly on the Circumference of the outer tubular body ?
• the outer tubular body (3) rotates around the inner stationary tubular body (2). It is driven in a known manner (see DE-PS 29 41 802) and rotates in the direction of the arrow (8) around the inner tubular body (2).
• the bores with the outer circumference (1 *) of the tubular body (1) forms the narrowing part (22) which, in addition to the negative pressure in the gap (20), also contributes to pushing material still adhering to the outer circumference (l 1 ) through the openings (3) inward again before these openings remove the casing area (2a ) of the inner tubular body (2) in which the nozzle strip (4) is arranged.
• a steel belt (5) running from left to right in direction (6) is provided as a conveyor belt underneath the so-called roto-former formed by the tube bodies (1 and 2), which in the exemplary embodiment is perpendicular to the direction of the bores (12) and the position of the openings (4) below the rotoformer.
• This steel strip (5) is passed at such a small distance from the outer circumference (1 ') of the outer rotating tubular body (1) that its surface, the droplet mass emerging from the two openings (4 and 3) coming to cover (23) detected, which sticks to the surface of the band (5) and in the further movement of the band (5) in 1-
• the distance between the steel band (5) and the circumference (1 *) of the outer tubular body (1) in the order of magnitude between 0.5 and 2 mm, the distance depending on the product and toughness must be variable.
• the distance between the belt (5) and the Rotoformer should therefore be adjustable within these limits, which is possible in a simple manner by adjusting the entire Rotoformer relative to the belt guide frame.
• a thread (24) will pull from the opening (3) to the drop location on the belt, which will be the longer the greater the distance between the circumference (l 1 ) of the tubular body (1) and the band (5).
• a thread winding roller (7) is provided which rotates about its axis (26) in the direction of the arrow (8), ie is arranged to rotate in the same direction as the outer tubular body (1).
• the circumference (7 ') of the thread winding roller (7) lies almost on the circumference (1') of the tubular body (1). In this contact area, the peripheral surfaces of the tubular body (1) and the thread winding roller (7) are therefore moved in opposite directions. The thread winding roller (7) therefore removes the threads (24) adhering to it from the circumference (1 *) of the tubular body (1) and ensures that these threads no longer become in the area below the thread winding roller (7) and therefore do not tear off.
• the thread winding roller (7) winds the threads in the right area of its circumference (7 '), in which the threads are marked with (24'), again on their circumference and ensures that the threads are drawn off upwards and therefore not on the tape (5) fall back.
• the heat inherent in the individual micropastilles (25) is sufficient to melt the tearing point of the thread.
• the cooling micropastilles therefore have a rounded shape.
• the thread winding roller (7) can also be provided with a concentric bore (9) for heating, if this is desired in order to keep the drawn-off threads flowable enough so that they come back to the surface (1 *) of the tubular body ( 1) can be submitted. It can prove to be unnecessary to heat the thread winding roller (7).
• the thin wound threads are also heated up again by the surface of the rotating tubular body (1) heated from the tubular body (2) to such an extent that they obtain a free-flowing state.
• the outer tubular body (1) is provided with a large number of the smaller bores (3). For example, 30,000 to 60,000 passage openings (3) can be provided over one meter of the length of the outer tubular body (1). This large number allows a high production rate.
• the material to be processed into micropastilles should generally have a viscosity greater than about 1000 cP. This desired viscosity can also be achieved with a few exceptions by regulating the temperature on the tubular body (2).
• FIG. 6 shows a modification of the device of FIG. 5 insofar as a rotating cooling roller (30) is provided instead of the moving cooling belt (5), the circumferential surface (31) of which is in the same way as the conveyor belt (5), is moved past under the tubular body (1) of a so-called roto former, which is otherwise identical to that in FIG. 5.
• the reference numerals used there have therefore been retained.
• the partial masses (23) that are formed, as described in FIGS. 1 to 4 are grasped by the surface (31), which, however, does not pass towards or from the openings (3) here needs to be moved away because the dosing of the openings (4 and 3) which come to coincide takes place.
• the pile (25) may pull threads (24) which, however, do not fall back onto the surface (31), even without the arrangement of a thread winding roller (7), as in FIG. 5, since they are taken from the counterclockwise rotating tube body (1) upwards and tear off. If this does not take place depending on the material, a thread winding roller (7) according to FIG. 5 can of course also be provided in the embodiment of FIG. 6.
• the diameter of the cooling roller (30), as can only be seen in FIG. 6, is generally chosen to be many times larger than the diameter of the tubular body.
