Definitions

  • the invention relates to processing soybeans with crushing for flocculation before extraction in a method for extracting soybean oil and soybean meal.
  • the soybean contains a lecithin-containing oil of approx. 20% and protein of approx. 36%.
  • the separation is carried out, whereby the oil is obtained and the extracted material is used as feed meal, the extraction usually being carried out by solvents.
  • Today two types of meal are produced, a so-called normal meal with a protein content of approx. 44% and a high-quality meal whose protein or protein content is approximately between 49-50%.
  • the protein content is increased by separating the bean hulls, which mainly contain fibers and other fibers.
  • the beans are heated in a shaft dryer cooler to approx. 90 ° C and then cooled in the cooler to temperatures of approx. 10 ° C above ambient temperature.
  • the aim of this process step which brings about a moisture reduction of approx. 2% by weight, is that the husks become brittle, burst open and detach from the actual bean kernel.
  • the whole beans are broken in the cold state with two-stage corrugated roller mills with the aim of exposing the shell parts and the core parts.
  • the broken material is separated into core parts and shells using vibrating sieves, whereby the shells are suctioned off according to the vacuum cleaner principle.
  • the remaining fraction still contains too large a proportion of protein and oil-containing core particles and must therefore be divided into shells and core parts in two further stages.
  • This material cleaned from trays, is then conditioned.
  • the product temperature is raised again to approx. 60-65 ° C, which lowers the viscosity of the oil enclosed in cells and the previously hard bean break becomes plastic, so that the fragments can be stabilized with as little effort as possible on the subsequent flaking roller mills, approx. 3 mm thin flakes can be rolled out.
  • the object of the present invention is to make the method of the type described in the introduction more economical.
  • the process should run continuously and the complex buildings should be superfluous.
  • the economy should mainly be achieved with savings in energy consumption.
  • Energy savings are achieved simply by bringing the material to be processed only once, in the fluidized beds, to the highest level of the thermal process of the technology. Also due to the fact that there are already smaller objects with short diffusion paths when heated.
  • the mechanical disassembly takes place in two steps and in the plastic state of the core parts, so that there are few fine and flour core parts. Since the material is sighted before it is warmed up, the system for recovering the oil and protein-containing particles only needs to be designed for a fraction of the total volume of the material to be processed. A practically perfect separation of the shell parts is achieved, so that a better quality of the high-quality soybean meal can be produced.
  • the description relates to a drawing, in which a diagram of an advantageous system for carrying out the method according to the invention is shown.
  • the beans to be processed come via a line 25 into a first fluidized bed 1, to which a further fluidized bed 2 is assigned.
  • the two fluid beds are arranged one behind the other. With the system shown, the high-quality meal can be produced with a protein content of approx. 49-50%.
  • the soybeans are heated uniformly in the first fluidized bed 1 with a hot air temperature of 165-170 ° C to 75 ° C.
  • the residence time of the material in the fluidized bed is less than 2 minutes. Due to this dwell time, no significant diffusion occurs, so that a maximum of 0.5% moisture is removed from the imported beans. This is very desirable for reasons of mass balance. It has been shown that this rapid heating of the beans is sufficient for the shells to become evenly brittle and to be detached from the kernels. All imported beans are warmed up evenly.
  • the heated beans are fed from the fluidized bed 1 via a line 26 to a single-stage corrugating roller mill 3 and from there to a downstream hammer mill 4.
  • the beans with the loosened shells are mechanically disassembled, which is a first step for separating the shells from represents the cores.
  • the beans are divided into two halves in this processing stage.
  • the previously thermally detached shells detach and are exposed.
  • the bean sprouts are also exposed.
  • the material processed in this way is now led into the second fluidized bed 2 against the exhaust air flow from the second fluidized bed 2, in such a way that the shells and the fine to flour parts produced during processing are discharged with the exhaust air.
  • the material is guided against the exhaust air flow via a distribution controller 5, where it is entered into a number of viewing channels 6 in the fluidized bed hood.
  • a suitable device for evenly distributing the material to be introduced into the exhaust air flow would also be exhaust air pipes designed as sifters on the fluidized bed hood of the fluidized bed 2.
  • both the shells and the fine and meal core parts and, in the case of extreme sighting, the germs can still be separated.
  • a mixture of shell parts, germs and fine and flour parts on the order of 15% of the throughput A falls on the shell side. This value can be reduced to at least 10% if the germs are not extracted.
  • this value also means that the further separation of shells and the material to be recovered has to be designed for only 15% of the system output.
  • the mixture of shell, germ and core parts, i. H. Fine and flour parts is led via lines 44 to a cyclone device with cellular wheel locks 12 and is separated from the air.
  • a particle mixture is also added to this mixture, which has been separated from the exhaust air of the first fluidized bed 1 in the cyclone devices 8 and 10 and is brought here via a transport device 15.
  • the mixture comes from a transport device 16 via a line 29 into a classifier 17.
  • the separation into a germ or germ parts -fine core parts fraction and a shell / flour fraction takes place.
  • shells and flour are separated from one another in a 1-deck sieve 21 with a 1 mm sieve and the valuable oil- and protein-containing flour is returned to the main product stream via line 32 before flocculation or via line 49 before extraction fed.
  • the amount of flour produced is approx. 1% of the plant output.
  • the seed parts / fine core parts fraction, which was obtained on the classifier 17, is fed via line 33 to the main product stream from line 28 via the common line 36 together for breaking onto the roller mill 23.
  • the shell-free half or coarser core parts, which have entered the second fluidized bed via the viewing channels 6, are fluidized there, the shell parts, which may still be adhering, being detached by the mutual friction of the particles and being discharged with the exhaust air.
  • the final product temperature is also regulated in this fluidized bed 2 and at the same time, in conjunction with the regulation of the first stage, moisture reductions of between 1 and 2% can be set.
  • the amount of air required for fluidizing the fluidized beds 1 and 2 is essentially circulated, specifically through lines 42, 43, 46 and 40. Only the moisture removed from the material, ie. H. The amount of air required for the extracted water is fed to the system as fresh air via line 47 and discharged as exhaust air via lines 41 and 24. Due to the small amount of exhaust air, a minimal environmental impact is achieved, the lowest possible energy consumption is guaranteed and an optimal use of the energy is ensured.
  • the air is heated in the system shown here by direct combustion of gaseous or liquid fuels.
  • heat exchangers In addition to this air heating solution, there is also the option of supplying the heat required to heat the material to the fluidized bed via heat exchangers.
  • heat exchanger tubes built into the fluidized bed, which are heated with steam, thermal oil or the like.
  • the material comes from the fluidized bed 2, as does the material after the classifier 17 or after the 1-decker screen 22 through the lines 33 or 34 in the warm state into the commercially available two-stage roller mills 23, in order to be broken warm there .
  • This hot crushing results in an increase in throughput and a saving in specific energy costs compared to conventional cold crushing.
  • the break obtained in this way corresponds to that of the cold-broken beans except for the flour content in the sieve analysis and is just as easy to flake.
  • the total flour content in cold-broken beans is approx. 5%, that in warm-broken half beans is only approx.
  • the method according to the invention simplifies and reduces the number of process stages by combining individual stages and eliminating other facilities. On the one hand, this is the elimination of the tempering level and thus the temperature silos. Furthermore, the material is only warmed up once and not cooled in between. The process is ongoing.
  • the separation devices for processing the mixture that is discharged with the exhaust air are only to be designed for 15% instead of 100% of the plant throughput, as is the case with the conventional method.
  • the flour content in the material to be extracted is only a maximum of 50% compared to today's methods. This may be expected to improve the operating conditions, for. B.
  • the cleaning of the oil from its scrap particles is also simplified.
  • the air volumes are largely recirculated and only small amounts of exhaust air are released into the environment.
  • the amount of exhaust air released to the environment in the conventional process by drying and cooling in the shaft dryer and by the shell separation is more than twice as large.
  • the air contains a larger amount of dust, since the amount of flour on the raw gas side is over 5%, in contrast to 1% in the process of the plant throughput according to the invention.
  • the higher dust content on the raw gas side inevitably leads to the same type of dedusting a higher dust content on the clean gas side.
  • the total emission of the conventional system is consequently several times higher than the emission of the method according to the invention. Even if the dedusting rate that can be achieved by the higher exposure to the cyclones is twice as good, it is still five times higher. It contains the previously necessary conditioning by reheating the material for flocculation.
  • the removal of moisture can be regulated at least between 1% and 2%.
  • moisture regulation is only possible within very narrow limits and is inevitably at least 2%; this makes the method according to the invention much more flexible. Drying in a fluidized bed is much more economical and leads to a much more evenly warmed and therefore more uniform product.
  • the degree of demolding in the method according to the invention is at least equally good.
  • the so-called normal meal can also be produced from the soybeans on the basis of the information provided.
  • the beans are quickly warmed up in the first fluidized bed 1 and fed directly into the second fluidized bed 2.
  • the two fluidized beds are shown separately in the diagram, but can also, and usually are, combined in an apparatus separated by partitions.
  • the beans are kept warm in the second fluidized bed 2 and then they are guided via line 28 to break at the roller mill 23.
  • the so-called normal meal with a protein content of about 44% is obtained after the subsequent flocculation on the flocculation apparatus 24 and the extraction, since the bean shells are included.
