Definitions

  • the invention relates to a method for producing pellets according to the preamble of patent claim 1 and to a device for carrying out the method according to the preamble of patent claim 7.
  • EP 2 536 555 B1 to take a pellet press with a motor, by which a rotor is driven. Due to the rotation of the rotor, forces are supposed to be exerted on a starting material that is filled in there, which is then pressed into pellets.
  • the collection container is a component of the device, that there is an outlet opening in the collection container, that at least one pair of interacting pressing tools are arranged directly adjacent to the outlet opening, which are designed as screw shafts or pressing rams, between which the starting materials are filled and passed through compressed into a pre-compacted starting material, that the waste heat produced by the compression of the starting material is collected and passed on to a heat exchanger, that the pre-compressed starting materials are transported away by means of a conveyor, that the heat exchanger is arranged in the area of the conveyor and the absorbed waste heat is sent to the raw materials for their drying, and that the raw materials dried in this way are conveyed to the pelleting device and are pressed by this into the individual pellets with a liquid content of 15% to 20%, on the one hand an optimal energy conversion is achieved within the device, because the The waste heat given off by the pre-compacted starting materials is collected by the heat exchanger and transferred to this in the area of the conveyor for further drying out, and on the other hand the lawn clippings can be
  • the lawn cuttings have a liquid mixture that is extremely protein-rich, which is pressed out of it during the pre-compacting by the press tools arranged in pairs and interacting and is collected in a suitable collecting basin. Animal feed can then be produced from this protein-containing juice, so that this component of the breed cut can also be profitably marketed by the operator of the device.
  • the device therefore represents an overall concept for processing grass into individual pellets with a final liquid content of around 15% to 20%.
  • Such a device is equipped with an extremely small footprint compared to the container for the temporary storage of lawn clippings and the lawn clippings are processed immediately , so that unpleasant odors, intermediate storage and the removal of voluminous grass bales are no longer necessary.
  • no unpleasant fermentation gases that can cause odor nuisance are produced during the interim storage of grass bales, because the grass clippings are immediately pressed, dried and processed into the individual pellets.
  • the processing processes that run through the method steps according to the invention save energy and bring the operator of such devices additional income; the fee-based disposal of voluminous racial cuts is also completely eliminated.
  • the process steps are extremely energy-saving and therefore environmentally friendly.
  • the components obtained from the lawn clippings namely the protein-containing liquid portion and the dried pellets, can be used after the processing steps to make animal feed and in further production steps for other products, such as paper bags made from grass or compressed animal feed in the form of pellets.
  • a device 1 can be seen, through which individual pellets 2 with a liquid content of 15% to 20% are produced from a liquid-containing starting material 3, for example grass.
  • the device 1 initially comprises a collection container 4 which has a filling opening through which the starting materials 3 can be filled. Below the filling opening of the collecting container 4 there is an outlet opening 4'.
  • two pressing tools 5 and 6 are provided immediately adjacent to the exit opening 4 ′, which are set in rotation by a motor 7 .
  • the pressing tools 5, 6 work together in pairs and are designed as worm shafts.
  • the rotation of the two screw shafts 5 and 6 is in opposite directions and the starting materials 3 filled into the collection container 4 are drawn in between them and precompacted in a known manner.
  • Two components are thus created from the liquid-containing starting material 3 during the rotation of the two pressing tools 5 and 6, namely on the one hand a pre-compacted starting material 10 and a liquid portion 15 pressed out of the liquid-containing starting material 3.
  • a grid 18 in which a large number of passage openings 19 are incorporated.
  • the pre-compacted starting material 10 thus falls onto the grid 18 and the pressed-out liquid 15 passes through the passage opening 19 into a collection basin 16 positioned below the grid 18.
  • the liquid 15 is therefore filled into the collection basin 16 and can then be transported away and further processed, for example, as animal feed or be used.
  • the pre-compacted starting materials 10 deposited on the grid 18 are then according to FIG figure 4 passed on to a conveyor 11. Due to the pre-compression process between the two pressing tools 5, 6, considerable waste heat 8 is produced when the liquid-containing starting material 3 is pressed, because the starting material 3, in particular grass, has an extremely high protein content. When proteins are compressed, waste heat is usually generated 8.
  • a heat exchanger 9 is provided in the area of the two pressing tools 5, 6, through which the waste heat 8 that occurs is collected and temporarily stored.
  • the heat exchanger 9 gives off the absorbed waste heat 8 to the pre-compacted starting materials 10 as soon as they have been conveyed by the conveying device 11 in the direction of the pelletizing device 12 . Consequently, the pre-compacted starting materials 10 undergo further drying in the area of the conveying device 11 in order to reduce their liquid content to 15% to 20% after leaving the conveying device 11 .
  • the heat exchanger 9 is therefore located in the area of the pressing device 5, 6 as well as in the area of the conveyor device 11.
  • the correspondingly conveyed starting materials are identified by the reference number 13 after leaving the conveyor device 11.
  • a flap 23 which is controlled by a motor 22 , is assigned to the conveying device 11 adjacent to the heat exchanger 9 .
  • the flap 23 can thus be opened or closed by the motor 22 .
  • a fan 21 is provided in the area of the flap 23 , which fan is set in rotation by the motor 22 .
  • the moisture content and the temperature inside the conveying device 11 can thus be measured by means of appropriate temperature sensors or moisture meters. As soon as the measured values exceed or fall below the specified limit ranges, there is an automated injection of Ambient air or the temperature present in the interior of the conveying device 11 is increased by means of heaters or heat radiation, which acts directly on the starting material 10 . These process control measures are carried out by means of a control device 25 which is electrically connected to the motors 7, 14 and 22 and to the sensors and liquid meters (not shown).
  • the pelleting device 12 usually consists of one or more press rams, which are controlled by a motor 14, which is also electrically connected to the control device 25.
  • the ram presses the dried starting materials 13 through a matrix, as a result of which such a high pressing force acts on the starting materials 13 that they are pressed into the individual pellets 2 .
  • the pellets 2 can be swirled inside the pelletizing device 12 or further dried if corresponding measurement results are recorded by the control device 25 which require such measures.
  • FIG 3 one of several constructive possibilities for precompression of the liquid-containing starting materials 3 can be seen.
  • Two pressing tools 5, 6 are aligned in such a way that an air gap is formed between them, between which the starting materials 3 pass and are consequently precompacted between the rotating pressing tools 5, 6, which are designed in the form of worm shafts, and which is contained in the starting materials 3 contained liquid portion 15 is squeezed out.
  • the pressing tools 5, 6 can also be designed as a press die or the like.
  • the device 1 according to the invention and its individual processing sections mean that the lawn clippings in the form of liquid-containing starting materials 3 can be processed directly into the individual pellets 2 .
  • the collection container 4 can be mounted and attached to or removed from the device 1 as a component.
  • the collection container 4 could also be part of a grinder and collect the grass 3 immediately after the lawn was cut.
  • the collecting container 4 accordingly transfers the collected grass 3 directly to the two pressing tools 5, 6 arranged adjacent thereto, so that the lawn clippings 3 are processed immediately.
