Definitions

  • the invention relates to a continuous process for the production of pelleted compound feed from a feed matrix and one or more solid additives.
  • Animal feed is often given in pelleted form, as compound feed, ie as a mixture of several feed components.
  • additives are usually added to the compound feed, such as enzymes, vitamins or antibiotics, the proportion of which is usually low compared to the main components.
  • the components forming the compound feed are mixed, conditioned in the presence of steam, pelletized in a pelleting press and then cooled.
  • US Pat. No. 6,056,822 describes a general method for any type of animal feed in which feed additives, such as enzymes, are dissolved in cooled form in the so-called "PPA (Post Pelleting Application) method", that is to say following the pelleting process
  • PPA Post Pelleting Application
  • the advantage of this method is that the substances applied do not suffer any loss of effect due to the effect of heat as a result of the conditioning step preceding the pelleting of foodstuffs, but the disadvantage is that the additives can not be applied in powder form to the pellets
  • technically complex devices are necessary to enable the dosing, dissolving and spraying of enzyme solutions
  • another disadvantage of the PPA method is that the additives to be applied are not always homogeneously on the feed are distributed.
  • DE 4,306,514 describes a method and a device in which, within the pelleting machine, lignin-sulfone-based pressing aids are added to the feed to be pressed. With this method, however, only those liquids can be sprayed or atomized onto the pressed material, which does not prevent processing of the press material in the press due to high moisture content. Another report Part of this method is that a homogeneous mixing of the added liquid with the pressed material is not guaranteed in this way.
  • WO 99/51, 107 shows a process for the preparation of fish feed, in which dissolved enzymes are added to the main feed components already before the conditioning step.
  • the enzyme transglutaminase used in this case serves to catalyze a ratcheting of proteins in the feed and also stabilizes the shape of the pellets produced.
  • the advantage of this method is that the enzymes are better mixed with the feed, resulting in a homogeneous distribution of all additives.
  • the feed mixture, including the added enzymes undergoes very great stress during the conditioning and the subsequent pelleting step. This stress is greater the higher the temperatures used and the residence times of the feed in the conditioning and pelleting unit. This has the consequence that the enzyme activity of the end product is very strong or at least considerably limited. For this reason, the feed mixture can be exposed to a maximum of 60 0 C and the addition of the additives takes place in comparison to the PPA process in a very large excess.
  • WO 98 / 54,980 describes a process in which dissolved enzymes are formed with a stabilizer into granules, which then with the feed main components a
  • Carbohydrates of existing granule carrier material show increased stability, yet they must be used in large excess in order to compensate for the loss of effect during the conditioning and pelleting process can. Another disadvantage of this method is also to be seen in that the
  • the object is achieved by a continuous process for producing pelleted compound feed from a feed matrix and one or more solid additives by pretreatment with steam, pelleting in a ring die press with a rotating ring die with radially through holes, which is arranged in a fixed housing and which leaves an internal space in which one or more rollers are arranged which rotate at a constant distance from the inner wall of the ring die, with one or more feed matrix feeders and for the one or more additives into the interior of the ring matrix press, and cooling the pelleting mill.
  • mixed feed characterized in that the one or more solid additives are added after pretreatment with water vapor and before or during pelleting in the ring die press.
  • the method is based on the method steps of conventional methods for producing compound feed, after which the main feed components cereals, legumes, by-products of the food industry are mixed individually or as premix in a mixer and then fed to an apparatus, wherein a conditioning in the presence of water vapor, often at temperatures in the range of 60 0 C to 90 0 C with a water vapor content of 2 to 3.5% saturated steam based on total amount of feed, in particular in a conditioner or an extruder is performed.
  • the treatment with steam serves in particular to improve the germ reduction to increase the feed hygiene and the pretreatment for pelleting.
  • the steam-pretreated mixture is then dropped into a pelleting press, often a ring die press.
  • the pellets obtained from the pelleting press are cooled, for example on a belt cooler or in a cooling tower.
  • Ring die presses are known and comprise as an essential component a ring die, usually a steel ring, with radially through holes, which rotates in a fixed housing.
  • the holes are usually arranged equidistantly, they may have the same diameter or different diameter from each other, which are constant or variable over the entire bore length. In particular, the holes may be cylindrical or conical.
  • the ring die leaves an inner space in which one or more, for example, two rollers are arranged, with a constant distance from the inner wall of the ring die, in the range of 0.1 to 8 mm, or in the range of about 0.1 to 4 mm, rotate.
  • the feed mixture is in this case pressed into the holes and exits at the other end of the same, where it is cut by fixed knives as pellets.
  • the ring die press has one or more feeder feed feeders.
  • one or more, usually heat-labile additives of the feed matrix formed from the feed main components are added after the pretreatment thereof with water vapor.
  • this can take place in the feed matrix feeder, often a chute.
  • the one or more additives are added to the interior of the ring die press via another feed device other than the feeder matrix feeder.
  • a compressed tube that is to say a tube which does not terminate flush with the inner wall of the annular matrix press, but protrudes into the interior of the same.
  • This further feed device for additives can advantageously be equipped with a vapor barrier. As a result, caking of the additives present as solid is avoided by the water vapor originating from the pretreatment step.
  • the additives may be added to the interior of the ring die press at different heights.
  • the additive or additives are often active substances, for example vitamins, enzymes, for example phytase, xylanase, glucanase, amylase, cellulase, hemicellulase, protease, lipase, pectinase, phosphatases, probiotics, for example Enterococus ssp., Lactobacillus ssp. Bacillus ssp., Pediococus ssp., Antibiotics; Carotenoids, organic acids and amino acids; they are advantageously supported on an inert carrier added, in finely dispersed form or in the form of granules.

  • the mass flow of the feed matrix before or after the pretreatment with water vapor or the flow rate of the pelleted compound feed is continuously recorded and the measured values are used to control or regulate the mass flow of the solid additive (s).
  • a further advantage is that the temperature in the conditioning step does not have to be limited to taking into account the thermal stability of the additives, whereby, for example, sufficient pasteurization and even more stable pellets can be achieved.
  • the method according to the invention is based on the addition of additives in solid form, which eliminates the need for both time-consuming and exact dispensing of solutions, as well as adhesion problems of additives applied to the pellets via a solution.
  • the recovery rates of the often expensive additives in the end product are significantly higher in comparison to known processes due to the significantly lower thermal load in the process according to the invention.
  • the invention also relates to the feed pellets which are produced directly according to the method of the invention. Relative to the amount of active substance used, they have less thermally denatured / decomposed active ingredients (additives) than feed pellets according to conventional production with mixing of the additives before the conditioner, for example in the main mixer based on identical production conditions in the conditioner and in the pelleting press.
