Use of peeled rape seeds.

[0001] The invention concerns a procedure for the treatment of rape seeds, whereby these are peeled and separated into cores (Parenchymgewebe and Keimwurzel) on the one hand and bowl portions on the other hand and whereby the cores are submitted to one or more pressing for Ölgewinnung and Feststoffund of ölhaltiger Presskuchen remain, after the generic term of the requirement 1, as well as a use of a Presskuchens and a powdered product after the generic term of the requirement 13.

It is well-known, rape seeds, to use by pressing for the Ölgewinnung. From the EP 1,074,605 B1 is further well-known to peel the rape grains before their pressing and Kernund of bowl portions separate. From the bright, yellow nuclear portions by pressing rapeseel oil is then won, then likewise, a yellowish color pleasant for customers aufweist.

In the case of such pressing the difficulty places itself that only about a third of the press property results about two thirds as high-quality oil and as feststoffund ölhaltiger Presskuchen verbleiben.

It is further well-known to supply to the remaining Presskuchen again essentially black-grey bowl portions and to submit in such a way received mixture further pressing, over thereby the altogether won oil portion too vergrössern.

After this further pressing still remaining, feststoffhaltige Presskuchen is by the again supplied bowl portions with antinutriven ingredients of altogether grey-greener color and becomes already therefore only than animal fodder or admixture for this verwendet.

The invention is the basis the problem, a high-quality use of Presskuchen during the rape processing too erreichen.

The invention solves this problem by a procedure, with the characteristics, the requirement 1 as well as by a new use according to requirement 12 and by a powder with the characteristics of the requirement 13. Regarding further arrangements and characteristics of the invention becomes on the dependent requirements 2 to 11. and 14 verwiesen.

According to invention not alone the pressed out oil can be used by the procedure as food, but also a Presskuchen so that the total utilisation rate of the rape seeds rises substantially, remaining thereby. Because the Presskuchen is submitted to a further meal procedure, results a fine powder, that as Grundoder filler for human food suitably ist.

In particular the further meal procedure covers a cryogenic grinding, so that also with a relatively high remainder oil rate in the supplied grinding stock grinding without sticking the tools together taken part in the meal procedure possible ist.

As grinding stock portions of the Presskuchens in frozen form are supplied particularly favorably, so that the oil portions not when liquid can withdraw. It continues to be favorable, if during this further meal procedure striking the supplied grinding stock in a pinned disc mill comparatively insensitive to sticking together stattfindet.

Alternatively or additionally knows the further meal procedure a de-oiling of the supplied grinding stock, in particular by extraction, cover, so that also by this measure remainder oil rate in the finished Presskuchen can sink and its processing facilitates ist.

If excluding nuclear portions of the rape grains without addition of bowl portions are supplied to the further meal procedure and used in the following than Lebensmittelgrundoder - filler, it is guaranteed that in such a way developing material keeps the bright color of the cores, without by bowl portions in its aesthetic effect to be impaired. Also in the bowl contained antinutrive portions as for instance waxes or Polyphenole become in such a way from the formed food ferngehalten.

It becomes favourable so far fine husbands that the received Grundoder filler trains a powder with grain size of for instance from 100 IJm to 500 IJm. Thus this powder is then good as Grundoder filler for dry spices, spice mixtures or spice preparations, in addition, as stirable portion in spice sauces geeignet.

Favourably the developed Grundoder filler can be interfered also in Wurstwaren and their Nährwert and volume vergrössern.

The more finely the formed powder is, the rather can it also than healthy and feed-worth-rich Grundoder filler in baking goods or also into other food masses as for instance Snacks, Müsliriegel or the like interfered werden.

The use one during processing of rape seeds received and nuclear portions of the rape seeds of containing Presskuchens as Grundoder filler for human food is separate beansprucht.

Further advantages and characteristics of the invention result out in the design represented and in the following described remark examples of the article of the Erfindung.

In the design shows:

Fig. 1 a roughschematic flow diagram of a procedure according to invention, Fig. 2 one detailregards from different process steps from Fig. 1, in accordance with in Fig. 1 represented flow diagram become, which calls supplied and still unsorted rape seed A.A also rape seed - first in a processing it sorts A in such a manner that those far rape grains A.E a to a large extent same size which can be processed haben.

These are then introduced into a mechanism S for peeling and thus into a bowl parliamentary group S.G and a nuclear parliamentary group S.E getrennt.

A pressing of the bowls is possible; here however is. in Fig. 2 only pressing P of the cores S.E drawn in, which are then supplied to a far fine meal mechanism K. Both once RB or several times gemahlener Presskuchen RD can be submitted to the Feinmahlen. Cores S.E also ungepresste can also included into the Feinmahlung werden.

Here cryogenic grinding is accomplished, which works with frozen grinding stock, so that the relative to high remainder oil portion in the grinding stock K. smearing or sticking the machines together does not lead B kann.

When result of the Feinmahlens will a fine property K.D receive, some rieselfähiges powder with grain size of approximately 100 IJm, until in approach of a Gauss' distribution trains 500 IJm. Due to the use only the cores without bowls the powder K.D has a bright colouring. This powder K.D can find, then as human food use. In particular thereby Grundoder of fillers are applicable into spices, spice mixtures, spice preparations or spice sauces. Due to its bright powder structure the received fine property can be used also well in spice scatterers for powdered spices as filler and be replaced there for example lactose or Dextrose. Contrary to many other Ölsaaten rape has a mild-spicy flavour and supported from there the Gewürzaromen.

Likewise it is possible to interfere the received fine property K.D as Grundoder filler in Wurstwaren or into other food masses or to use this in baking goods, there it, as mentioned above, a mild-spicy flavour without unpleasant sharpness hat.

In detail with the processing of the first unsorted raw rape seed A.A first in the sieve jigger 1 a cleaning of the rape seed is made, so that trimming A.C and caring grain A.D can to be segregated to be able and the cleaned rape seed A.B in a seed dryer 2 be dried, approximately in the Luftstrom.

In such a way cleaned, dried and an approximate standard size of exhibiting rape grains A.E are then supplied to peeling S, where they are broken first in a DoppeI rolling mill 3 in the gap between the rollers; with it, a sieve jigger 4 supplied developed rape break S.A., in which incipient crack S.C and fine break S.D are segregated and which so-called utilizable break S.B of far to a separator 5 one leads up, in this the bowls S.F segregated and with the incipient crack S.C and fine break will become the S.D altogether as a so-called bowl parliamentary group S.G a silo 6 supplied and depending upon targeted application processed. This subsequent treatment can be for example adding to a Presskuchen of the nuclear parliamentary group S.E, which is stored temporarily in a parallel silo 7. The portion of altogether won oil can be increased by this admixture and repeated pressing, the Presskuchen is then however with the dark bowl portions transferred, so that its optical shape - and thus the application type as food raw material reduced is for example re-used as Viehfutter and it wird.

If the optics does not play a role, also such Presskuchen can in the way, like it for the nuclear parliamentary group S.E descriptive is further used in the following, werden.

This peeled nuclear parliamentary group S.E becomes a more einoder multi-level. Press unit P supplied. As in Fig. , are there two worm extruders 8, 9 are exemplarily drawn 2 in vorgesehen.

In the worm extruder 8 a first pressing of the peeled rape S.E is accomplished, so that the nuclear oil RA of first pressing can be won. The nuclear cake RB of first pressing can be submitted of a second pressing in the second press 9, so that the oil-exploited rises and can the nuclear oil RC additionally, be won. The nuclear cake P.D of second (or a further) pressing can just like the nuclear cakes RB of first pressing and/or also ungemahlene rape cores S.E as individual parliamentary group or as mixture from these. Parliamentary groups altogether the Feinmahlung K supplied werden.

The Feinmahlung K is a cryogenic, is called here that the grinding stock K.B after going through a metal separator in a radiator II, here an advertisement egg snail radiator, frozen, into this radiator 11 here liquid nitrogen K.A introduced, so that still in the grinding stock contained the oil portion (typically over the 10% for second and 22% for first pressing) does not smear the meal mechanism or verklebt.

The frozen grinding stock K.C is struck in a pinned disc mill 12 and thus into the desired fine property K.D of fine granulation in the order of magnitude of 100 IJm up to 500 IJm. converted and in a collector 13 by way of introduction. The view gas K.E becomes over one. Filter 14 and a blower 15 from the fine property K.D remove. The nitrogen K.F can in a cycle again for cooling used werden.

The further meal procedure K must cover not compellingly a cryogenic meal procedure, but can additionally or alternatively in particular also a further de-oiling before grinding the supplied grinding stock, in particular by extraction, umfassen.

Because excluding nuclear portions of the rape grains without addition of bowl portions are supplied to the further meal procedure, also the received fine grinding stock K.D remains lightyellowish and without the possibly for food unwanted and. in the bowl portions of contained Anteile.

With the invention for the first time a use is during processing received and nuclear portions of S.E of the rape grains of containing Presskuchens P.B, P.D from rape grains A.A shown one as raw material for human food. The creation of value from the rape seed is substantially increased, there no longer only the oil, but also the Presskuchen than high-quality material for food production used wird.

In such a way received powder K.D is thereby in different way usable, approximately as raw material for in particular spices, spice mixtures, spice preparations or spice sauces, for Wurstoder baking goods or other food masses. Heating or chemical changing of this powder K.D up thereby, just as little an inoculation with mushrooms or other additives is not necessary, but it is direct as Lebensmittelgrundoder additive verwendbar.

The powder K.D can be worked on however also in different kinds further, in particular also with that. Powder formed food, for example also heats up or frozen werden.
