Definitions

  • the invention relates to an animal bedding of the type corresponding to the preamble of claim 1, a method for its production and the use of a thickener therefor.
  • Animal bedding is primarily intended for pets, especially cats.
  • a variety of embodiments of such animal bedding are available commercially, as can be seen from a compilation in the magazine "Test", issue 2/93, pages 74/75.
  • the base or carrier material of the animal bedding can be natural organic material, inorganic mineral material or a mixture of both. Shredded wood or straw and even waste paper occur as a natural organic material. Bentonite is used as an inorganic material in many compositions. However, other naturally degradable minerals such as sepiolite, pearlite and gypsum are also used. However, there are also artificially produced mineral substances, such as ground aerated concrete or hydrated calcium silicate hydrate, as described in EP 44 574 B2, page 4, last paragraph, or a calcium sulfate dihydrate according to DE 27 25 687 AI.
  • a purely organic animal litter comes from DE 37 32 807 AI, which describes an animal bedding made of pressed rohtrohmehl, which is briquetted by pressing, the straw meal briquettes are then crushed into fragments with an irregular outer surface, ie a granule of a few millimeters grain size.
  • DE 41 01 243 AI describes a mixed form in which the base material is cellulose, cellulose derivatives and / or cellulose-containing materials, to which a mineral weighting agent and a thickener and / or binder have been added, the thickeners being more organic, synthetic or can be inorganic in nature.
  • the mechanism of water retention as such is not important. It can be chemical absorption processes, swelling processes or hygroscopic processes in porous materials. Purely surface adsorption is also not excluded. The water should remain bound to the animal bedding and disposed of together with it.
  • known animal bedding show an additional property which justifies a particularly economical use of the animal bedding, insofar as the bedding layer is wetted by the animal's body fluid and does not seep through the entire bedding layer, which necessitates a renewal of the entire bedding layer made, but only the upper parts hit directly by the liquid, which hold the liquid immediately and prevent the infiltration into the lower layers.
  • the upper portions covered by the liquid stick together, so that lumps or plate-like soft chunks form on the top of the animal bedding layer, which as the top layer is removed from the animal bedding layer with a small shovel or fork can be without the underlying layers are affected.
  • Soil contamination from body fluids is limited to relatively sparse areas, while the rest remain intact. This allows a certain amount of animal bedding to be used much better.
  • the invention has for its object to provide an animal bedding that is largely naturally degradable and forms clumps.
  • Guar flour (claim 2) has proven to be surprisingly suitable as a natural organic thickener, which is also carried out as guar or guar gum and the ground endosperm is the seeds of the Indian guar tree, which is one of the legumes (Cyamopsis tetragonoloba) (Römpps Chemical Lexicon, 8th edition, page 1557; Lexicon of auxiliaries for pharmacy, cosmetics and adjacent areas, HP Fiedler, 2nd edition, 1981, pages 450/451).
  • the guar flour is a gray-white powder and has about eight times the thickening power of starch. This high thickening power and the largely medical and food safety of guar flour in combination with its still tolerable price make guar flour appear as a particularly advantageous component of the animal bedding according to the invention.
  • guar flour in the animal bedding is approximately in the range from 5 to 40% (claim 3).
  • the amount to be used depends partly on how pronounced the clumping effect should be, and partly on the type and structure of the water-retaining natural organic material which generally forms the bulk of the animal bedding.
  • the limit results from the costs of an increasing proportion of guar flour.
  • animal litter is almost entirely degradable in this way and only includes minor other fractions of auxiliaries, for example to improve wettability, to adjust the pH and the like, which will be discussed in more detail below.
  • cellulose, cellulose derivatives or cellulose-containing materials are considered as mostly the main constituent of animal bedding, primarily wood particles according to claim 6, which have not undergone any further processing apart from the size reduction and are correspondingly economical.
  • the wood particles can have a size distribution and can be present as a mixture of more granular and more flaky particles (claims 7, 8).
  • Wood particles in the form of shredded shavings have proven to be particularly useful.
  • the largest dimensions of the wood particles used can be in the range from 0.5 to 5 mm, in particular in the range from 1 to 2 mm (claims 9 to 11).
  • the animal bedding can contain a surfactant to promote the wettability of the particles of the animal bedding, preferably in an amount of 0.05 to 1% by weight of the total amount (claims 12, 13).
  • a surfactant to promote the wettability of the particles of the animal bedding, preferably in an amount of 0.05 to 1% by weight of the total amount (claims 12, 13).
  • Good wetting of the surface of the animal litter particles increases the transition cross-sections available for rapid water absorption and also promotes the penetration of water into the particles.
  • an alkaline component can be present for setting an optimal pH (claim 14).
  • the alkaline component may contain NaOH or Na 2 CO 3 , expediently, according to claim 16, in addition to NaOH or Na 2 CO 3, a proportion of pH buffer substance is present to form a buffered alkaline component.
  • the total amount of the buffered alkaline fraction should be present in the range from 0.1 to 1.5 percent by weight.
  • the animal bedding is present according to claim 19 as pressed, practically abrasion-free granules.
  • This property is important so that the animal bedding does not get caught on the animal's fur and is carried around in the home by the animal, for example a domestic cat, as would be the case if a powdered structure were permitted.
  • the parts described above, for example the wood particles, are therefore contained in the individual granules and compacted into these granules. Techniques are known for producing such a granulate.
  • the dimensions of the granules are given if at least 90% of the granules have a largest dimension in the range from 2 to 5 mm and a ratio between the largest and the smallest dimension below have of 5: 1 (claim 21). This is intended to describe a certain degree of convexity of the granules, in which fibrous portions of granules are excluded which would adhere to the skin as much as a powder.
  • the starting mass with the constituents mentioned can, for example, be pressed, for example extruded, into shaped bodies which can be used directly if, for example, These are small pellets with a diameter of 5 to 8 mm and a length of approx. 10 to 15 mm, or which are then crushed to form the granules by cutting or crushing.
  • This technology is known per se from DE 37 32 807 AI.
  • the comminution is followed by a screening which is intended to separate the small and light components which have come about during the comminution from the granules.
  • the thickener is used in the first phase as a binder for the pressing process and only performs its function as a lump-forming thickener later when the animal litter is used.
  • the invention also extends to the use of a natural organic thickener as a lump-forming constituent in a natural organic material holding water (claim 23), the organic thickener being present in an amount of 0.5 to 100 percent by weight of the total weight of the Animal litter can be present (claim 24), that is, the case should also be included that the organic thickener forms the animal litter completely.
  • Guar flour is also the preferred organic thickener from the point of use (claim 25).
  • the mixture was compacted into pellets using a pellet press (Kahl press), which were then comminuted again using a cutting machine (and / or intermediate rollers).
  • the fraction between 2 and 5 mm of the largest dimension was sieved off and represents the usable animal bedding.
  • the granulate has a white-brown color that is reminiscent of sawdust.
  • the structure is woody, i.e. the material shows a certain amount of thermal insulation, which the animals find pleasant.
  • the addition of NaOH and borax serves to adjust the pH to about 7.5 to 8.5, while the material without this addition has a pH of about 5.7, which is below that for the optimal effect of the guar Mehls located area. If borax is used alone or as part of a composite pH buffer substance, guar forms a rubber-like gel if the borax is activated with a time delay to the guar (approx. 5 to 10 minutes later).
  • the bulk density of the finished animal bedding is about 480 g / l.
