Definitions
- the invention relates to a device for producing granules or lozenges from flowable material with a circumferential hollow roller provided with pressing recesses and radially outwardly adjoining pressing holes and a pressing roller running on the inside thereof, which engages with pressing tools in the pressing recesses and that Press nip supplied material is squeezed through the squeezing holes and is deposited in the form of granules or pastilles on a cooling surface located underneath.
- press tools are designed as external teeth of the press roll and the press recesses are one
- the present invention is based on the object of designing a generic device with regard to the interaction of the hollow roller and the press roller in such a way that a further variety of materials, in particular low- to medium-viscosity substances, can be reliably pastilled into small to medium-sized lozenges.
- FR-PS 1 459 319 it is known for the processing of powdery masses into granules to provide at least two rollers with interlocking circumferential profile grooves and ring ribs, the interacting rollers being arranged with their axes in a common horizontal plane the press nip between these rollers extends in the vertical direction.
- the powdery material is partially brought to a plastic consistency by moistening before passing through the rollers.
- the use of such a device for processing flowable material is not possible, since this would cause the material to flow through the press nips formed between the two rolls and no individual granules could be produced, but rather the material in the form of strands on a possibly pre-cut ⁇ seen cooling belt would be stored.
- FIG. 1 shows a schematic cross-sectional view of the device according to the invention
- FIG. 2 shows a partial longitudinal section of the device according to FIG. 1;
- the device according to the invention has a hollow roller 10, which has internally circumferential, axially spaced profile grooves 12 as press recesses. At the bottom of the profile grooves 12, through-holes 14 penetrate the jacket of the roller and through which the melt is expressed.
- a press roll 16 runs, which is provided with circumferential ring ribs 18 as a pressing tool, and these ring ribs 18, which are adapted to the profile grooves 12 in cross section, engage in the profile grooves and press out the material through the press-out holes 14.
- the press roll 16 is suspended via link 20 from a product feed pipe 22 which concentrically penetrates the hollow roll.
- the material exits through slots 24 of the heated product feed pipe 22 and from there reaches the press nip between the hollow roll and the press roll.
- a spur gear 28 is placed on its shaft 26, which meshes with an internal ring gear 29 of the hollow roll.
- the press roller 16 is height adjustable via an eccentric arrangement in order to be able to change the depth of engagement between the ring ribs and profile grooves.
- a part of the circumference of the hollow roller is surrounded by a heating jacket 30, which is designed at the same time as a suction shaft 32 for the developing gases.
- This arrangement can be designed according to DE- ⁇ S 40 13 405.
- a loading older product guide 34 is arranged over an angular section of the hollow roller which is free from the heating jacket 30, and this has the task of stripping off the excess product and finally feeding it back in through holes in the hollow roller.
- the resulting gap 36 is of great importance for the formation, and this is determined depending on the viscose acetate of the products to be processed.
- the granules or pastilles 38 which are expressed through the squeezing holes 14 and thus produced, are placed on one below the
- Hollow roller arranged moving u. cooled surface 40 stored which can be designed as a cooling belt or as a cooling roller.
- the annular rib 181 has the cross section of an isosceles triangle.
- the ring rib 182 has the shape of an equilateral trapezoid.
- the annular rib 183 has converging side surfaces which are bridged by an arc.
- the cross section of the ring rib 184 has the shape of an equilateral triangle, the base being offset inwards, so that cylindrical ring surfaces are formed on the roller between adjacent ribs 184.
- Such cylindrical ring surfaces between adjacent ribs are also formed in the ring ribs 185, the profile of which is rectangular.
- the cross section of the profile grooves 12 corresponds to that
- the device according to the invention is particularly suitable for processing low to medium-viscosity substances, whereby small to medium-sized lozenges are produced.
