In die Hohlwalze (1) wird in den sich in der Drehrichtung verjüngenden Spalt (11) das zu granulierende Material eingegeben, das dann durch das Ineinanderwirken der Zahnleisten (4, 5) zwangsweise und volumet­risch jeweils nach unten herausgedrückt wird. Die sich bilden­den Tropfen (41) fallen auf ein Kühlband (7) und können dort erstarren. Die neue Vorrichtung weist den Vorteil auf, daß die Masse zwangsweise mit definiertem Volumen ausgepreßt wird, daß aber durch das Zusammenwirken von rotierenden Teilen eine große Pro­duktionsgeschwindigkeit möglich wird.

Process and apparatus for producing pastilles

Bekannte Einrichtungen mit zwei ineinanderrotierenden Rohrkörpern, die mit zyklisch zur Deckung kommenden Öffnungen versehen sind, erlauben es, im Inneren des inneren Rohrkörpers zugeführtes Material in fließfähiger Form zu vertropfen. Diese so erzeugten Tropfen härten dann auf einem darunterliegenden Kühlband aus. Die Größe der Pastillen ist durch die Notwendigkeit, Tropfen zu bilden, nach unten hin beschränkt. Es wird daher vorgeschlagen, auf die Tropfenbildung zu verzichten und das Material durch Berührung des Bandes (5) unmittelbar aus den Öffnungen der rotierenden Körper (1) herauszuziehen. Es wird dadurch möglich, Mikropastillen mit wesentlich kleineren Abmessungen herzustellen. Known devices with two interlocking tubular bodies, which are provided with cyclically congruent openings, allow material supplied in the interior of the inner tubular body to drip in a flowable form. The droplets generated in this way then harden on an underlying cooling belt. The size of the lozenges is limited by the need to form drops. It is therefore proposed to avoid the formation of drops and to pull the material directly out of the openings of the rotating bodies (1) by touching the band (5). This makes it possible to produce micropastilles with significantly smaller dimensions.

Granulating device with a perforated hollow cylinder

ABSTRACT OF THE DISCLOSURE A rotary extruder with an outer cylinder having inner teeth at its inner surface intermeshing with the teeth of an inner pressure roll. The process material passes through rows of passages in the bottom of the grooves between the teeth of the cylinder, being forced by the teeth of the roller. A feeding device delivers the material to be extruded into the upstream gap between the cylinder and the roller. The device has an improved versatility for materials of different consistency.

Device for extruding fluent materials

Apparatus for extruding flowable substances from two cylindrical containers of which the first is provided with openings on its periphery and is rotatable about the outer wall of a cylindrical inner container to which the extrudable substance is fed and through a row of openings which, with relative rotation of the containers, coincide cyclically with the openings of the outer container, falls in the form of drops onto a conveyor or cooling belt arranged below it and solidifies there. The row of openings is provided in a nozzle bar which can be attached to the periphery of the inner container.

Apparatus for the production of granulated material

ABSTRACT OF THE DISCLOSURE An apparatus forms granulates from a flowable viscous mass. The mass is delivered to a tubular body and flows downwardly from a lower slit thereof in the form of drops. An endlessly revolving belt travels across the slit in tight engagement therewith. The belt has orifices therein which intermittently open the slit to admit the passage of the drops. The drops fall onto a conveyor which travels below the belt in the same direction and at the same speed as the belt.
