Definitions

  • the invention relates to a method for compaction of flowable solids, in particular of powders, flours or similar substances, preferably by packing or bagging according to the preamble of patent claim 1.
  • the invention further relates to a device for compacting flowable solids.
  • a discharge device is completely emptied, wherein the bulk material quantity is determined and taken into account as an afterflow.
  • the discharge during the dosing is at least once empty dangers, the mass of the empty and the filled discharge is weighed and the difference forms the to be considered downstream.
  • a two-shaft discharge screw (EP-A-0131063) is known for such discharge devices whose spirals mesh with one another. In the discharge screw, there is a negative pressure to avoid an impairment of the leadership.
  • the bulk material can be pressed or compacted, i. be vented without vacuuming, with an expansion after the removal of the pressing or compression element is possible.
  • a compaction space is filled with the bulk material and the compaction space is subsequently reduced in size. Subsequently, the compaction space is sealed gas-tight and subsequently enlarged again to produce a negative pressure. Thereafter, the compacted bulk material flows out through a discharge opening.
  • WO-A-9007452 there is provided a method of filling and evacuating large containers provided with a neck or valve for e.g. As hygroscopic products disclosed in which the containers are filled in an evacuated chamber. The vacuum can be adjusted by adding inert gases.
  • the invention has for its object to develop a method for compaction friessfileer solids, in particular of powders, flours or the like substances, preferably by packing or bagging, which allows storage and transport of the compacted solids with low space requirements and stable in position.
  • the effort should be reduced and the process reliability increased.
  • the storage periods for the compacted solid can be very long.
  • Compaction e.g. of white flour leads to the extension of the shelf life (no oxygen supply) and to the reduction of the packaged volume.
  • shelf life no oxygen supply
  • the stackability of the packaging containers and their handling respectively. Palletability improved.
  • insect or mold growth and fat oxidation are slowed down.
  • the invention further relates to a device for compacting fiiessfileer solids, in particular of powders, flours or the like substances, preferably by packing or bagging.
  • the device includes a storage chamber and a downstream this bag chamber, both of which are evacuated.
  • the vacuum formation should take place in the shortest possible time, possibly with pre-vacuum. Furthermore, a filling of tubular bags can be carried out, wherein instead of a sack neck, a bag forming device is used and the product is also pre-weighed.
  • the device according to the invention for sacks such as tubular bags can be integrated at individual stations as well as in carousels.
  • carousels it is also particularly advantageous to carry out a stepwise or pre-vacuuming. Instead of venting, a negative pressure of a previous station can be used.
  • the invention will be described below in an embodiment with reference to a drawing.
  • the drawing shows the device for compaction in a schematic representation.
  • the apparatus includes a storage chamber 1 for flour or the like and a baghouse 2 located underneath, wherein between the two chambers 1, 2, a slide 5 as a shut-off and a projecting into the bag chamber nozzle 6 are arranged. Both chambers are provided with a vacuum connection 4.
  • the storage chamber 1 also has a filling opening, which can be sealed with a lid 3.
  • a bag to be filled (not shown) is attached in a conventional manner.
  • the bag in the bag chamber 2, not shown, the bag a certain shape giving elements may be provided.
  • the nozzle 6 can be supplemented with a Sackverschliess shark.
  • the storage chamber 1 is preceded by a weighing and metering device.
  • the storage chamber 1 may alternatively contain product for the filling of several bags, so that the ventilation and venting can be reduced.
  • the storage chamber 1 is provided with a weighing and metering device.
