Definitions

  • a product is greased together with a greasing liquid in such a way that the greasing liquid not only remains on the surface, but penetrates into the interior
  • the greasing is carried out after the shaping process by means of spray drums or mixers in a conventional manner, there is the problem that the product to be greased only absorbs the greasing liquid on the surface, or that the greasing liquid penetrates the product only slowly by means of the capillary action, which is slowed down with increasing viscosity or closed or small pores
  • the amount of fat that can be applied to the product by means of spray drums or mixers is limited to 5 to 10% of the amount of granules
  • One improvement in this regard is shown and described in Japanese patent application with publication number HEI3-180 163 (1991), in which a product is brought into an obliquely upward-facing auger by means of a metering lock, an oil sump with a predetermined value being placed in a lower part of the inclined auger The level at which the product falls and is moistened when it is transported upwards is maintained.
  • the screw is additionally depressurized by means of a vacuum pump, ie the product which is required after the greasing liquid is in a predetermined vacuum during transport
  • the level of the so-called oil sump can be adjusted and varied
  • the oil absorption improves from the aforementioned 5 to 10% of the amount of granules in the conventional method up to 13.5% of the amount of granules in the aforementioned system
  • Fish feed recipes which usually contain a large proportion of fish meal, are extruded gently, for example in extruders, at temperatures around 120 ° C with a water content of 20 to 30%.
  • this plastic material in the extruder expands at temperatures above 100 ° C associated vapor pressure to solidify as a bread-like, foamy structure when it emerges from the extruder and thus when the moisture escapes and the associated cooling
  • such a dried product is placed in a mixer, preferably in a paddle mixer, which stands on weighing cells, so that, based on the measured product weight, the predetermined amount of greasing liquid can be added.
  • This predetermined amount of greasing liquid is metered in while rotating the mixer to the Wetting the surfaces of the product parts
  • the mixer is placed under negative pressure, as a result of which the air is evacuated from the capillaries of the product
  • the product parts have a predetermined temperature, which corresponds to a low viscosity of the greasing liquid, in order to be able to penetrate well into the capillaries or pores of the product during the step, according to the invention, explained later.
  • This step according to the method consists in that after the generation of the vacuum, while simultaneously greasing the product, the vacuum in the mixer, and thus the surroundings of the product, is relaxed, so that the atmospheric air that is now entering the mixer again, the greasing air on the surface of the product Liquid in the evacuated pores or capillaries
  • the greasing liquid is added below 10%, which is also advantageously carried out according to the invention and in the case of very porous product parts, the greasing liquid is advantageously sprayed in the mixer in order to achieve a uniform wetting of the surface
  • spraying can be dispensed with, i.e. the liquid to be greased can be absorbed by the product, i.e. by the product parts during the mixing process, partly from the bottom of the mixer
  • the greased product or the greased product parts are advantageously fed to a cooler or a ventilated storage cell at a temperature of approximately 40 ° C.
  • the advantage of the method according to the invention, on the one hand - as already mentioned above - is that significantly more fat content per amount of granules is bound to the product than according to the prior art method in which only the wetted product is subjected to a vacuum without Mixing a relaxation of the vacuum takes place, in which the greasing liquid can be absorbed more in the pores or capillaries
  • the figure shows a system according to the invention with the device according to the invention, shown schematically
  • the figure shows schematically a plant for the production of extrudates and the greasing of these extrudates according to the invention.
  • the invention is not restricted to the use in such a plant, but can be used in all plants which produce other porous product parts, such as pellets, expander pellets etc.
  • the floury or granular product is known to be moisture-moist for the treatment in the subsequent extruder or expander , prepared for temperature and consistency
  • extruder or expander is a machine known per se, for example a twin-shaft extruder of the BI-EX brand, manufactured and sold by the applicant, or an expander, for example with the designation DFEA 220 or a cube press with the designation "KUBEX” , also manufactured and sold by the applicant
  • the extruded or expanded product is placed in a dryer, for example a belt dryer, also manufactured and sold by the applicant, in which the extrudates or expandates are dried and cooled
  • the exhaust air from the dryer 5 is collected by means of an exhaust hood 6 and fed to a cyclone 7.
  • the clean air is discharged as exhaust air 8 into the atmosphere or into another filter (not shown).
  • the separated solid substance of the cyclone 7 is collected in a collecting container 9
  • the product dried in the dryer 5 is placed in an intermediate container 10, which as a rule has approximately the volume of the subsequent mixer 12, in order thereby to give the mixer 12 the possibility of working in batches. run of the intermediate container 10, a slide 11 is provided, which allows the contents of the intermediate container 10 to pass through the subsequent mixer 12
  • the mixer 12 stands on weighing cells 13, so that a predetermined amount can be added to the mixer 12, on the one hand to let the slide 1 close when the amount has been reached and on the other hand to have the corresponding amount of greasy liquid added, for which purpose the product quantity measured by the weighing cells in Mixer of a controller 19 is signa ert
  • the controller 19 closes the slide 11 for a predetermined amount in the mixer and, on the basis of the pressure weight signaled by the weighing cells 13, calculates the predetermined, correct amount of greasing liquid which, by means of a metering pump 18, flows from a container 17 for the greasing liquid into the mixer 12 is pumped
  • a control satellite 19 1 of the controller 19 puts a vacuum pump 20 into operation after a predetermined time, in order to mix the mixer and.
  • This negative pressure evacuates the pores or capillaries of the individual product parts, which manifests itself in the product, for example, in that the air emerging from the pores or capillaries generates foam bubbles in the moisture lying on the surface of the individual product parts
  • control satellite 19 1 controls a relief valve 21, to which is connected between the mixer 12 and the vacuum pump 20 on the connecting line from the mixer 12 to the vacuum pump 20
  • the mixer is added as a percentage of greasing liquid as experience has shown that the product to be greased is able to absorb, so that when the mixer 12 is emptied, no greasy liquid that has not been absorbed remains at the bottom of the mixer
  • the expansion valve can be provided as a pressure control valve, so that the air that flows back in flows back in a controlled manner

Abstract

L'invention concerne un procédé et un dispositif pour incorporer des matières grasses dans des produits alimentaires granulés pour animaux, par ex. des extrudats, des pastilles, des pastilles expansées etc., avec un liquide fournisseur de graisse. Les pastilles produites dans l'extrudeuse ou dans la zone d'expansion de la presse (4) sont séchées dans une unité de séchage (5) puis passent par un contenant intermédiaire (10) avant d'arriver à un mélangeur (12). Au moyen d'une pompe de dosage (18), une quantité prédéterminée de liquide fournisseur de graisse est incorporée dans le mélangeur (12) et répartie à la surface des particules de produit lors du processus de mélange. Après une période prédéterminée, une pompe à vide (20) produit une dépression dans le mélangeur de façon à évacuer l'air se trouvant dans les capillaires ou les pores des particules de produit. La dépression dans le mélangeur (12) est ensuite supprimée par une soupape de détente (21) de sorte que l'air pénétrant dans le mélangeur et dans les pores ou les capillaires des particules de produit transporte le liquide fournisseur de graisse se trouvant à la surface des particules ainsi que du liquide fournisseur de graisse supplémentaire dans les pores ou les capillaires jusqu'à ce que ces derniers soient remplis de façon à ce qu'une proportion élevée d'environ 30 % de liquide fournisseur de graisse soit liée dans les pores ou les capillaires des particules de produit. Une fois ce processus achevé, le produit est introduit dans un contenant intermédiaire (14) d'où il est distribué en tant que produit final au moyen d'un élément de distribution et de dosage.
