Definitions

  • This invention relates to a method of producing feed pellets, in which moist feed pellets in one process simultaneously are subjected to negative pressure, undergo a drying process and the pores of the feed pellets are filled with oil in order to achieve a lower total temperature load thereon.
  • the invention also relates to a plant for use in the implementation of the method, the plant generally comprising an oil-filled pellet chamber, which is preferably connected downstream of a pelleting machine, an extruding device for feed pellets or similar pellet-forming device, and in which the pellet chamber is followed by a separating unit, separating the pellets from surplus oil-
  • Feed pellets for fish and animals are industrially manufactured in a multi-stage process.
  • the ingredients are mixed into a dough-like mass, which is formed into feed pellets by high pressure and high temperature, for example in a so-called extruder, after which the feed pellets are dried, filled with oil and cooled.
  • the pressure is relieved from warm feed pellets, typically holding from 100 to 140 °C, to ambient pressure, the feed pellets expand due to internal pressure and liquid boiling out from the feed pellets. The expansion results in the feed pellets acquiring a porous 5 structure.
  • the porosity or the specific gravity of the ready-shaped product may be an important quality criterion of several types of food and feed products, including feed pellets for . farmed fish.
  • the porosity of the product is important for the o possibility of adding liquid nutrients which are absorbed into same; the porosity is further of importance for the floating properties in a suitable medium, and it is important for textural criteria like crispness, feeling to the mouth and toughness.
  • the porosity is important s with a view to the ability of the feed pellets to absorb oil in the manufacturing process, and for the floating properties/buoyancy in water when given out.
  • the most common method of increasing the porosity is to increase the amount of mechanical and thermal energy supplied to the raw materials in the extrusion step of the production process.
  • the basic mixture contains a surplus of vapour after extrusion, the surplus vapour will expand and result in greater porosity.
  • compressed gas can also be supplied to the extruder, as disclosed in US patent document No. 5 587 193.
  • WO No. 9503711 and No. 9816121 are described means of reducing porosity after the extruding stage, by drawing out positive pressure and surplus vapour inside the extruder.
  • the feed pellets After leaving the extruder or the pelleting machine or similar pellet-forming device, the feed pellets are cut into pieces of a desired length. Considerable remaining moisture in the expanded feed pellets entails that the feed pellets must be dried in order to have a long shelf-life. Such drying can take place in several ways, and some of these should be well known to a person skilled in the art.
  • a well-known drying method is drying of feed pellets in warm air.
  • a drier can be arranged with one or more belts transporting the feed pellets through the drier.
  • Such a drier can be divided into several zones with different air temperatures.
  • the drier can also be arranged as a multistorey tower (vertical drier), in which the feed pellets are dropped from floor to floor at defined intervals .
  • the air temperature can vary from floor to floor.
  • These driers all have in common the long retention time, which may vary from 20 minutes to several hours, depending on the air temperature and the pellet size. This results in several well-known drawbacks.
  • the feed pellets are subjected to a long-lasting temperature load, which is unfavourable for the stability of sensitive raw materials, and it reduces the nutritional value of the protein in the feed.
  • the physical quality of the feed pellets can be judged only as the pellets leave the drier. Therefore, the o drying stage results in a long feed-back time for possible adjustment of operational parameters of the extruder or corresponding equipment. Since the capacity of a production line per hour is typically in the range of 5 to 10 tonnes, this involves that a considerable volume of faulty production s is on its way through the drier before necessary operational changes can be implemented. Thus, the effect of the adjustments cannot be judged until after another 30 minutes to 2 hours, etc.
  • 5 527 553 prescribes an oil temperature of 107 - 232 °C, with 135 to 190 °C as a preferred temperature interval.
  • oil temperatures will have an adverse effect on the heat-sensitive raw materials, and the high temperature can reduce the nutritional value of the protein. It may also initiate oxidation processes, which will cause a reduction in the product's storage stability. Extra energy is also required in order to heat the oil to such high temperatures.
  • the oil is not only to be absorbed into the feed pellets, but it also works as a transport medium to get the feed pellets away from the extruder unit.
  • US patent document No. 5 527 553 specifies only schematically how feed pellets and surplus oil should be separated after the process. It is indicated that oil and feed pellets are carried across a movable grid, where the oil runs off, while the feed pellets are carried forward to be packaged. Further it is specified that air can be blown over the feed pellets to enhance the running off, while at the same time a cooling effect is achieved. Practical experiments show that this does not give a satisfactory result, as the feed pellets will be covered by an oil film, which will result in a considerable amount of free oil when the product is packed in sacs.
  • the boiling point of water is reduced in reduced atmospheric pressure.
  • the boiling point of water is thus 100 °C by atmospheric pressure (1013 millibar), 80 °C by 474 millibar and 50 °C by 123 millibar.
  • the partial pressure of a gas in a liquid is proportional to the pressure above the liquid.
  • the pressure of the oil column above the pellet chamber will be negligible relative to the atmospheric pressure.
  • the pressure above the oil column, that the pellet chamber forms part of will be reduced, which results in a reduction in the vapour pressure of the water in the oil.
  • oil at a lower temperature than that specified in US patent document No. 5 527 553 can be used in order to dry the feed pellets. Thereby more favourable drying conditions are achieved as regards nutritional value and storage stability.
  • An object of the invention is to provide a method and a plant of the kind initially mentioned, to be used in the manufacturing of porous feed pellets, wherein better control can be maintained of the porosity of the feed products than by known technique.
  • Another object is to achieve a quicker drying of the product, while at the same time achieving a lower total temperature load on the product than by known technique.
  • a third object is to achieve better control of the feed absorption of feed pellets.
  • a fourth object is to achieve an energy-efficient process.
  • a fifth object is to obtain a process, in which the time from the formation of the feed pellet until the product is ready to be packed, is substantially shorter than by known technique.
  • a sixth object is to obtain a closed process, which reduces the risk of contamination, for example from the salmonella- bacterium.
  • a seventh object is to obtain a continuous process without intermediate storing and internal transportation of feed pellets.
  • these objects are realized by a procedure in accordance with the characterizing part of the following Claim 1, and by a plant of the kind initially mentioned for the implementation of the method, being formed so that it exhibits the features specified in the characterizing part of Claim 7.
  • the procedure is such, that feed pellets are produced by, discharged by or extruded by a pressure which is lower than the ambient pressure, feed pellets being discharged directly to an oil-filled chamber, in order to be transported subsequently in the oil flow to a separating unit, which separates the feed pellets from surplus oil, said separating unit being operated at the same or a different pressure.
  • a plant for the implementation of this method comprises an oil-filled pellet chamber interconnected in the plant downstream of the pelleting machine, and the plant distinguishes itself by said pellet chamber being arranged to allow a pressure lower than the ambient pressure to be maintained, for example in the order of 100-800 millibar.
  • the plant comprises a separating unit, which is arranged to operate by atmospheric pressure or by a pressure lower than the ambient pressure, for example in the order of 100-800 millibar, and such that the pressure in the pellet chamber may be different from the pressure in the separating unit.
  • this is normally done in practice by extruding feed pellets in a manner known in itself, but with the important difference that the extruder delivers feed pellets into said oil-filled chamber, which works at a reduced pressure.
  • the application of reduced pressure will in this connection give a lower boiling point,. i.e. little temperature load on the feed, as the temperature of the oil can be reduced to achieve the same drying effect as by atmospheric pressure.
  • Feed pellets subjected to reduced pressure will also expand more than they otherwise would, and increased evaporation of water contributes to the attainment of a more porous feed pellet.
  • the expansion can be controlled by adjustment of the negative pressure and by changing the oil temperature in the pellet chamber.
  • the retention of the feed pellets by the reduced pressure may be of short duration, in a typical case from a few seconds and up to one minute, after which the feed pellets are carried to a separation process for feed pellets and surplus oil to be separated.
  • Diet A contained 25 % wheat, 48 % fish meal and 27 % maize gluten (given in % of dry blend fed into an extruder before addition of water).
  • Diet B contained 17 % wheat, 54 % fish meal and 29 % maize gluten. The values are measured or analysed values, whereas the values in the column "Water content in non-greasy dry matter in finished product” are calculated values and indicate the effect of drying, as opposed to "Water content in finished product", which is a function of both oil absorption and drying.
  • the results show that both oil temperature and pressure are of importance for the water content in the final product.
  • the water content in the extrudate is of less importance for the water content in the final product.
  • the results also show that both oil temperature and pressure are of importance for the fat content in the final product.
  • a higher fat content indicates that the feed pellet has expanded more, accordingly increased porosity.
  • the results also show that the feed pellets are dried better by increasing oil temperature and by decreasing pressure. The feed pellets produced were of good quality.
  • a plant according to the invention for use in the manufacturing of feed pellets is provided with an oil-filled pellet chamber, which is arranged to be maintained at a pressure lower than the ambient pressure.
  • the oil-filled pellet chamber is connected to a separating unit, to which feed pellets are transferred, the separating unit similarly being arranged to be kept at a pressure lower than the ambient pressure.
  • the invention comprises a method, in which pelleting and drying are carried out at a first reduced pressure, whereas the subsequent separation of feed pellets and surplus oil is carried out at a second reduced pressure.
  • Said first pressure and said second pressure can be identical or different from each other.
  • the outlet of the pellet chamber can have a lock element arranged thereto, which makes it possible to take out formed feed pellets continuously or in batches, the negative pressure being maintained at the same time.
  • feed pellets are produced in a pelleting machine and carried from there into said oil-filled pellet chamber working at a reduced pressure.
  • the degree of negative pressure relative to the atmospheric pressure is adjusted with a view to the expansion wanted in feed pellets. This is done in cooperation with the adjustment of the oil temperature, which also affects the degree of expansion.
  • the method according to the invention provides essentially better control of the expansion, and porosity than action taken in a known manner before or during pelleting. The reason is believed to be that changes to single parameters in the pelleting process also affect other parameters of importance for a good result. This is because the pelleting process affects the physical and chemical structure of the raw materials by means of the same measures that control expansion, such as heat, water and pressure.
  • the pressure in the pellet chamber can be in the pressure range from 0 millibar up to just under atmospheric pressure, and will in typical cases be between 100 and 800 millibar.
  • porous feed pellets are produced in a manner known in itself, but with the new feature of feed-pellets being delivered to an oil-filled pellet chamber, which is maintained at a pressure lower than the ambient pressure, typically in the range one hundred to eight hundred millibar, and in which the oil temperature is maintained in a range above the water boiling point for the relevant working pressure, typically in the range from 50 to 180 °C.
