Definitions

  • the invention relates to a method for producing feed pellets, d.s. Extrusions, by homogeneously mixing the feed with 0.1 to 2 percent by weight of a powdered urea-formaldehyde resin and then pressing.
  • pellets d.s. cylindrical strands or strands with differently shaped cross sections, e.g. 1 to 20 mm and e.g. 2 to 50 mm in length and briquettes made from floury feed, in particular compound feed
  • advantageous properties such as preventing the components from segregating, lower storage and transport costs due to higher density, better dosing due to the good pourability and therefore particularly suitable in the case of non-manual feeding, lower feed losses, less sensitivity to changes due to air and light due to the lower specific surface area and better utilization of the feed by the animal due to chemical changes (digestion) of the feed during pressing.
  • Lignin sulfonate is mainly used as a pressing aid in compound feed. It has the disadvantage that between 1.5 and 10% is required, depending on the recipe, and this is usually in connection with molasses. However, high molasses levels prohibit high temperatures because molasses caramelizes. Lignin sulfonate dilutes the feed due to the necessary relatively high concentration, thereby reducing the nutrient content. This can only be compensated for by using high-energy feed, which is more expensive. In addition, absorption by fiber such as lignin sulfonate is slowed down. Finally, lignin sulfonate always contains sulfur dioxide, which has a laxative effect.
  • White clay also has the disadvantage that it dilutes the animal feed and reduces the nutrient concentration. It also has a low baking effect. The result is a little abrasion-resistant compact. In terms of binding effect, white clay is still behind lignin sulfonate.
  • Cellulose ether for example in the form of carboxymethyl cellulose, is only used in special foods because of the relatively high price. However, this substance also has the technical disadvantage of insufficiently binding high levels of fat in the feed.
  • the object was achieved according to the invention by homogeneously mixing a powdered urea-formaldehyde resin which was prepared by spray drying a glue solution and which had a molar ratio of urea to formaldehyde of 1: 1.6 to 1: 2 and a free formaldehyde content of 1 to 4 percent by weight has, in amounts of 0.1 to 2 percent by weight, based on the feed, with flour-shaped feed and subsequent pressing into strands.
  • the feed mixture is preferably heated beforehand, in particular with steam.
  • the pelleting process according to the invention is suitable for all floury individual feed and in particular compound feed.
  • Compound feeds are mixtures of vegetable, animal and synthetic organic and inorganic substances, e.g. Flour, soybean meal, fish meal, minerals such as monocalcium phosphate, dicalcium phosphate, trace elements in the form of magnesium oxide and copper sulfate and vitamins such as vitamin A acetate and vitamin E acetate.
  • Flour vegetable, animal and synthetic organic and inorganic substances
  • minerals such as monocalcium phosphate, dicalcium phosphate, trace elements in the form of magnesium oxide and copper sulfate
  • vitamins such as vitamin A acetate and vitamin E acetate.
  • this powder has a relatively high free formaldehyde content of 1 to 4 percent by weight, in particular 1.4 to 3 percent by weight and preferably 1.6 to 2.4 percent by weight. It has been shown that the higher the free formaldehyde content in the resin, the higher the abrasion resistance of the compacts. (The free formaldehyde content is determined by known methods, e.g. slurrying the powder in ethylene glycol and determining the free formaldehyde according to de Jong - De Jong et al, Rec. Trav. Chim. Pays-bas 71, 643 (1952).)
  • the free formaldehyde also has the further advantage that it is bound by the proteins, which are thus protected against premature breakdown in the rumen and reach the abomasum and / or small intestine without degradation.
  • Formaldehyde also preserves the feed. The taste is not affected and the feed retains a pleasant smell.
  • the urea-formaldehyde resins are mixed with the floury animal feed in amounts of 0.1 to 2 percent by weight. This has a clear effect at quantities above 0.1 percent by weight, which initially increases and only slightly increases at quantities above 2 percent by weight. The upper limit of the additional quantity is therefore limited primarily by economic reasons. Therefore, amounts of 0.15 to 1.5%, preferably amounts of 0.2 to 0.5% by weight are generally used.
  • the mixing of the urea-formaldehyde resins with the feedstuffs is expediently carried out in the usual mixers, e.g. Centrifugal mixers, screw mixers, twin screw mixers, vortex mixers, horizontal mixers, vertical mixers, batch mixers, continuous mixers until a homogeneous distribution is achieved. Then, after adding liquid and / or water vapor, the mixture obtained is pressed, depending on the pelleting method chosen, into pellets which are of the desired length, e.g. be cut between 2 and 50 mm.
  • mixers e.g. Centrifugal mixers, screw mixers, twin screw mixers, vortex mixers, horizontal mixers, vertical mixers, batch mixers, continuous mixers until a homogeneous distribution is achieved.
  • the mixture obtained is pressed, depending on the pelleting method chosen, into pellets which are of the desired length, e.g. be cut between 2 and 50 mm.
  • urea-formaldehyde resins have also been added to animal feed.
  • the present invention differs significantly in the measures, the objective and the results.
  • a particulate i.e. Non-floury feed is first treated with an amide, the feed is heated and dried, then a liquid, concentrated urea-formaldehyde condensate is applied and the feed is pelletized.
  • orange pulp is reacted with a condensate which has a molar ratio of formaldehyde to urea of 4.6: 1.
  • the amount of condensate is 12.5 percent by weight, which is considerably higher than in the process according to the invention.
  • the pig feed has the following composition:
  • the pellets show a hardness of 10.44 kg / cm 2 and an abrasion of 1.42%.
  • the pressing performance is undiminished compared to the comparison test without urea-formaldehyde condensate.
  • the urea-formaldehyde condensate is produced as follows.
  • the molar ratio of urea to formaldehyde is 1 to 1.9.
  • the water content is 3% and decreases to 2% after 1 week.
  • the bulk weight is 0.7 kg / i.
  • the grain size distribution is as follows:
  • pellets 5000 kg of pig feed complete feed mixture of the above composition are pressed without the addition of urea-formaldehyde condensate.
  • the pellets have a hardness of only 8.34 kg / cm 2 and an abrasion of 3.40% corresponding to 2.4 times the pellets produced according to the invention.
  • the carp feed has the following composition:
  • the pellets have a hardness of 10.1 kg / cm 2 and an abrasion of 1.51%.
  • the pellets were still in shape after 12 hours of remaining under water and are not dissolved. This is surprising since urea-formaldehyde glue is water-soluble and a gluing effect at this concentration is unknown.
  • lignin sulfonate content is 1.6%, i.e. 6 times the value for the formaldehyde-urea condensate.
