Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for removing the soybean epidermis from soybean embryo, a soybean raw material, by mechanical means.

BACKGROUND OF THE INVENTION The process described above is a technological substep in the processing of soybeans into soybean oil, which produces soybean flour as a by-product. Either remove the cloves altogether, or use as little as possible for the soybean skin to improve nutrition. In short, for this purpose, it is necessary to peel off the epidermis from the embryo in these 70 processes. However, by stripping the epidermis from the embryo, it is important to leave the soybean embryo as intact as possible, i.e. in the subsequent zoroses, making it difficult or even difficult to peel it off, and thus during this or the next process. (crush) into as large a portion as possible without creating dust or powder that would disrupt production.

Known methods for stripping the epidermis from the embryo utilize mechanical peeling equipment well known to the flour milling industry, utilizing known operating rules, but without the aforementioned inconvenient or obstructive dust or powder. Bring forth.

OBJECTS OF THE INVENTION It is an object of the invention to provide a method of the above-mentioned type which makes it possible to completely strip the epidermis from soybean embryos without producing any undesirable dust or powder. Additionally, is it a challenge to make the aforementioned method suitable for any variety of soybean material, pre-processed or non-pre-processed? Means to Solve The method taken to solve the above-mentioned problems is based on the principle of having an attached epidermis or epidermal part [the raw material, which is a dog bean embryo or an individual bean embryo part phantom]. is hit by a striking tool, and the raw material object hit is caused to collide against the wall at a constant and uniform speed along the flight path, so that the skin part is significantly separated from the eaves part due to the blow and collision, and the material object is struck for a long time. The raw material is guided to another point along the wall, and this point is provided and used for rubbing the epidermis that may still be attached to the eaves.

In general, claims 2 to 15 indicate alternative embodiments of the present invention.

Effects of the Invention The advantage obtained by the method of the invention is that all soybeans, even those containing moisture, can be directly peeled. In addition, pre-heat-treated soybeans can also be subjected to shearing forces in some cases in a toothed roller device in order to strip the epidermis from the embryo, thereby causing partial rupture and thus Soybean raw materials not only have soybean embryos (but also have soybean parts whose epidermis or epidermal part is removed), and because of this, soybean raw materials have objects of various sizes and various properties. I can do it.

EXAMPLE The soybeans, ie the soybean raw material, to be processed according to the illustrated example have already been heat treated beforehand, so that the soybean epidermis has been separated from the soybean germ, but still covers the soybean germ.

In some cases, after the previous heat treatment, the soybean skin' is still exposed to shearing forces, for example by means of sawn roller devices, which leads to rupture of the skin and simple separation of the soybean embryo into the upper part of the embryo. In some cases, the soybean embryo and part of the soybean epidermis may rupture. Each raw object of soybean 1, i.e. each soybean material, i.e. soybean raw material, which has been previously treated in this way, with the embryo or eaves part attached to it and still covered by the outer skin or epidermis part, is struck. Receives 9 blows from tool 2.

Such a blow applies a first mechanical action to separate the epidermis from the soybean embryo.

This blow is for the raw material that was hit! Throwing the snout so that it collides with the wall 4 in the flight path indicated by the arrow 3, the collision exerts a second mechanical effect on the object and causes a final weakening in the component of the object. lead to. This can be accomplished by breaking the soybean embryo into at least half, and at most approximately % of the half, without breaking it into dust or powder, and it is also possible to significantly peel off the epidermis or epidermal part from the eaves part. do. The raw material produced in this way is moved along the wall 4 and along the hole 5 in the wall at a residual velocity of the flying velocity of the raw material object.

By rubbing along the wall 4 with the edge of the hole 5 and against the wall of the hole 5, the parts of the skin that are still attached to the eave part are worn away. The holes 5 are at most twice the size of the largest part of the material to be guided. The above-mentioned treatment is carried out at a rate of approximately 20 m/sθ at the moment when the striking tool 2 strikes the proboscis of the raw material object.
If the raw material object is made to move at a speed of C, and if the speed of the struck and blown raw material object is in approximately the same speed range at the moment of collision with the wall 4, the first point to be obtained for all Leads to.

Advantageously, the wall 4 has perforations 5 in the sheath wall, the minimum internal diameter of the perforations being 1.3 to 1.8 times larger than the maximum part of the processed soybean material passing through the perforations. The damage of the skin part still attached to the eaves part, which may remain, in some cases, may be of a size of It is carried out at a fixed residual speed.

In the embodiment, the impact tool 2 is indicated by the arrow 3 in FIG.
It is a rotating tool that rotates in the σ) direction at a circumferential speed of approximately 2[1 m/sec]. In each case, four tools 2 are arranged in a cross-shaped manner, and these tools are grouped together in a cross-shaped rotor 22. Around the rotor 22, an impact wall 4 has a circular shape with holes 5. It is arranged as a 7-p wall.

The individual tools 2 are flat prismatic steel striking burls arranged in a row in each row. A gap approximately corresponding to the width of the two end faces of the tool exists between the tools.

The soybean raw material or the raw material objects forming it are placed in the circulation path of the tool so that each raw material object can be applied to the tool and only once before impacting the wall 4. You will be informed at the appropriate timing.

For this purpose, a chute 6 is provided in front of the cross-shaped rotor 22. The chute 6Q reaches a temperature over the entire length of the rotor 22. In such a chute, the soybean material to be processed is continuously and regularly stacked. The individual raw material objects slide downward along the falling line of the neat object and fall freely over the multi-stage waterfall-overflow 7 at the bottom of the chute 6 into the circulation path of the impact tool 2 of the cross-shaped rotor 22. The raw material object falls at a timing equal to the frequency of the striking tool 2 at the striking point 3, that is, at the moment when the tool approaches the striking point, it falls only four times per rotation of the rotor.

In addition to this timing, the raw material object falling along the falling line consecutively - times, for example 6 to 4 times, is also hit by the tool at the same time, and the force λ causes the same number of successive flight paths to fall onto the collision wall 4. It means to be thrown away. Moreover, it can be imagined that the human blood in the chute 6 is coated along the falling line, and the raw material objects are arranged one behind the other within the drop line and are continuous. Such miso is provided correspondingly to a multi-stage waterfall. Such a miso distribution corresponds to the distribution of the percussion tool 2 in the rotor 22. The distribution function of 0/neat means that the water stream is distributed into a stream, and this stream is divided into free-falling droplets over 70-min, and thus Comparisons can be made with well-known examples such as quartz devices, where a continuous curtain of water is produced.

Since energy is a function of mass, the kinetic energy of individual raw material objects of various masses, such as that occurring in Kajuchobegi soybean raw material, is determined by the fact that at the moment of impact and impact it is moving at a constant and the same speed. It is clear that the sizes would be different if not specified. It is large in the case of a large raw material object, and small in the case of a small raw material object.

From this it is clear that no (or very little) additional dust or powder is produced during the operation, and likewise that the raw material to be processed is equally (heavy) with respect to the mass of the raw material objects produced. It becomes clear whether the person is a type of person with a special talent or a type of extraordinarily talented person.

Experiments have shown that the edge of the hole 50), which is exposed to the impact of the raw material object, remains sharp if it is sharply cut by the raw material. The preferred shape of the holes 5 is an elongated gap-like hole, which extends parallel to the imaginary axis of the trajectory 3 of the raw material object.

It is advantageous to use a sheath wall 4 formed with a plurality of bars 42 of prismatic cross-section arranged parallel to each other and spaced apart, as shown in detail in FIGS. 3 and 4. Rir.

The spacing 51 thus provides the aforementioned minimum internal diameter of the elongated gap-like bore 5 opened between the ribs 42 .

It is advantageous if the thickness 45 of the rods 42 and the spacing 51 between the rods, ie the minimum internal diameter of the elongated gap-shaped holes 5, are of the same size. The cross-sectional shape of the prismatic rod 42 is a square with a chamfer on one side. The wall provided to catch the collision and to further guide the raw material object thrown into the flight path 3 is scraped off by the wall 44, where the upper wall 43 of the rod 42 points towards the imaginary axis of the flight path. For example, as shown in FIG. 6, the right wall 44 facing inside the /-p has an acute angle, approximately 70 to 75 degrees in the embodiment. This wall is located approximately parallel to the tangential direction of the flight path, and the material object to be flown is
The object is guided to a wall 43 located perpendicular to the flight direction of the object.

Preferably, the bar 42 is made of a wear-resistant or hard material in order to be subject to the effects of dog-picking during operation. In addition, the bar can be hardened or provided with a wear-resistant layer, for example painted. It is the common edge of walls 43 and 44,
The rods 42 forming the tube wall 4, whose edges remain sharp, are individually manufactured and heat treated. The rods are held together in the wall 4 by means of strips 41 which secure the rods and are arranged at right angles to the rods.

In the case of soybeans having a particularly abrasive skin, it is possible to impinge on the soybeans against a wall 4 formed as a full-walled cylindrical wall, as shown in FIG. Collision is wall 4
, but this wall extends only approximately half of its entire circumference and reaches as far as the lower end edge. The soybean material with exposed embryos slides under the edge of the end and is discharged under the free condition. A strut-like projection 46 is provided on the underside of the wall 4 in order to rub the epidermal part, which may still be attached to the embryonic part, as described above. Such projections are advantageously suitably shaped and distributed on the inner circumference of the wall 4. It is also possible to choose a wear-resistant material for the strut projections. The shape and distribution of the strut projections must be specifically adapted to the nature of the soybean to be processed.
