Definitions
- the invention relates to a method and a device for the gentle discharge of viscoplastic and viscoelastic material mixtures, in particular dough, from a kneading trough, in which the material mixture with the help of at least two counter-rotating spiral helix, the diameters of which partially overlap, in the axial direction along a mixing path is promoted without pressure.
- WO 92/17068 discloses a method and a device for the continuous mixing of substances into foams and doughs.
- the mixture of substances is mixed in a continuous double spiral kneading process by the opposite rotation of two rotating shafts and a viscoelastic structure of the mixture of substances is created.
- This mixture of substances is transported along the kneading trough with the help of the double spirals.
- the mixture of substances is stripped with known scrapers in known devices. These wipers are attached tangentially to the free shaft ends. With the help of the wipers, the constantly pre-sticking mixture of substances is brought into resistance against the conveying direction, which leads to
- BESTATIGUNGSKOPIE that the mixture of substances can be removed from the kneading device.
- the feed speed of the mixture of substances along the conveying direction is only very low in comparison to the speed of rotation of the mixture of substances around the shafts.
- a scraper By stripping the mixture of substances with the help of a scraper, a large torsional load is introduced into the mixture of substances. This torsional stress can lead to a loss of structure of the mixture of substances. This loss of structure has disadvantageous consequences for the further processing of the mixture of substances.
- the invention has for its object to enable a gentle discharge of the mixture of substances from the kneading device.
- the invention proposes a method in which the mixture of substances is fed along the conveying direction to a tapering trough provided with an opening and that the mixture of substances is released from the coils and the opening with the aid of at least two tools provided on the spiral axes is fed.
- the invention proposes a device in which the kneading trough tapers and has an opening, and in which at least two tools, each attached to the spiral axes, detach the dough from the coils and feed it to the opening.
- the detachment of the substance mixture by tools attached to the helix axes prevents the substance mixture from undergoing torsion.
- the tapering of the trough ensures that the
- the tools are applied to the helix axes in such a way that they convey the mixture of substances in the direction of the opening of the trough ensures that the mixture of substances can be discharged continuously at the opening of the trough.
- the tools are not arranged axially parallel on the spiral axes, but at an angle. Through this screw-like arrangement, the mixture of substances is transported through the tools in the direction of the tapered trough.
- At least two T-shaped tools are attached to the helix axes to detach the mixture of substances from the helices.
- the cross strut of the T-shaped tool is adapted to the incline of the trough.
- At least two further tools which are designed as a solid sheet and which convey the material mixture detached from the T-shaped tools to the opening of the trough, enable the material mixture to be discharged completely.
- These solid sheets reliably guide the mixture of substances to the opening of the tapered trough.
- the tools on the two axes are arranged so that they overlap without contact. The tools do not touch each other while the shaft pairs are rotating in opposite directions. Nevertheless, it is ensured that the mixture of substances that is located between the waves is permitted to be transported to the opening.
- the tools are adapted to the incline of the trough so that there is only a slight tolerance between the inner surface of the trough and the tool. This ensures that the mixture of substances does not remain between the tool and the trough, but is transported along the conveying direction.
- Fig. 1 shows a discharge device according to the invention.
- Two ends of the helical axes 102, 104 are guided in a tapered trough 100.
- the helical axes 102, 104 are guided through the bearings 114, 116.
- the T-shaped tools 106a, 106b are arranged screwed on the helix axis 104.
- further T-shaped workpieces can be attached to the helical axis 104 at the same height.
- the tools 110a, 110b designed as solid sheets are arranged downstream of the tools 106a, 106b.
- further tools can be arranged at the same height of the helix axis 104.
- the tees of the tools 106a, 106b are arranged at such an angle to the helix axis 104 that they adapt to the trough shape of the tapering trough 100. Furthermore, the inclination of the T-shaped tools 106a, 106b is angular with respect to the helix axis 104. It is thereby achieved that the material mixture is transported in the direction of the opening 120 when the helical axis 104 rotates.
- the T-shaped tools 108a, 108b are arranged perpendicular to the helical axis 102. Here, too, the T-shaped tools 108a, 108b are arranged at an angle with respect to the helix axis 102.
- the tools 112a, 112b which are designed as solid sheets, are arranged on the T-shaped tools 108a, 108b.
- the shape of these solid sheet metal tools 112a, 112b is adapted to the inclination of the trough.
- These tools 112a, 112b are also arranged at an angle with respect to the axis of rotation of the helix axis 102, as a result of which the mixture of substances is advanced in the direction of the opening 120.
- the discharge device shown works as follows:
- a mixture of substances which is conveyed along the conveying direction 118 by the spirals (not shown) is stripped off by the tools 116, 118 from the spirals.
- the helical axis 104 rotates clockwise and the helical axis 102 rotates to the left. Due to the angular arrangement of the tools 106, 108, the material mixture is transported further in the conveying direction.
- the tapering of the trough 100 increases the conveying speed of the mixture of substances, since the end of the trough is overfilled at the outlet of the trough Discharge mixture is reached.
- the tools 106, 108 In order to reliably discharge the mixture of substances from the opening 120, the tools 106, 108 have the tools 110, 112 arranged.
- These tools pick up the substance mixture and transport it further in the direction of the opening 120.
- the tools are arranged in such a way that they do not touch during the rotational movement of the helical axes 102, 104, but nevertheless overlap.
- the overlap of the tools ensures that the mixture of substances is also reliably transported in the direction of the opening 120 inside the trough.
- the shaft bearings 114, 116 are protected from contamination by the material mixture by the upstream trough 100.
- the discharge device described is particularly suitable for a gentle discharge of rye, mixed rye, wheat and fine dough.
