description

The invention relates to a principle for devices and methods which are used for the processing of masses, in particular chocolate masses. At least one swash plate is used for this principle. The operation of the swash plate is generally known for use with helicopters to control the rotor pitch, on the other hand, the swash plate is also at

Hydraulic pumps used.

Taumein or precession is generally the change of direction of the axis of a body when external forces exert a torque on it. Euler's equations are equations of motion for the rotation of a rigid body. To explain the principle of the use of the swash plate for these devices, one can imagine a gyroscope, which, if it loses momentum, with the

The lateral surface of the cone falls to the plane and then rolls around the apex of the cone. This rolling around the apex clearly shows the principle of the one used here

Swash plate.

State of the art

When mixing, crushing and vaporizing masses, in particular

Chocolate masses are usually used conches, which are provided in more or less cylindrical housings and with rotor (s), in relation to the volume of the mass small scraper. Shear and Versalbungswerkzeuge exhibit. The energy yields are correspondingly low. The temperature controls are usually only on the housing wall feasible, accordingly difficult and tr ge.

Mills are often built for a specific purpose and are not universally applicable. The contact time of the ground material is in roller mills between the rollers low, which is why it often needs several grinding passes. The setting options are low. It can usually only peripheral speed of the rollers, friction, grinding gap, and roller temperature can be adjusted. If these parameters are not sufficient, several passes or several rolls must be used. In ball mills or media mills, the energy input is usually introduced by the weight of the grinding media. The grinding media and the material to be ground are in a cylinder-like grinding chamber. The grinding speed and the

Energy contracts are difficult to control.

The various tempering and machines will not be discussed here. Only two methods are mentioned that have hardly been used in

Been brought into context. It is on the one hand, the method of tabulation, that is, it is on a worktop, which is preferably made of marble, warm chocolate mass with the help of a spatula as long as painted over the countertop, while the mass thickened and cools and it forms the crystals , Second, the vaccination process is mentioned in which the chocolate mass by means of

Seed crystallization can be crystallized.

Description of the invention

The invention is based on the object in an apparatus and a method for processing ground material and masses the energy input (mechanical and / or thermal) and the substance input (eg gassing) and the substance discharge (eg degassing) to increase to achieve the intended by the processing end state of the millbase or the mass faster than with the conventional means of the prior art.

To solve this problem, the invention provides a device for processing masses, in particular chocolate mass, ready, in which at least one swash plate (1) provided with an obtuse cone on its front side, is arranged so that the apex of the swash plate ( 1) on the axis of

Swash plate is located and the lateral surface of the swash plate (1) can extend to its outer diameter, wherein the swash plate (1) with respect to a counter-obtuse cone opposite surface formed and arranged is that a line extending from the cone tip over the lateral surface to the outer diameter of the lateral surface line of the swash plate (1) parallel to the counter surface

is arranged and so roll on the opposite surface and / or can tumble.

In the inventive method for the continuous preparation of masses, in particular for mixing and refining fatty masses, preferably using a device according to the invention, the mass by means of

Swash plates, especially between swash plates, sheared, anointed, fumigated, degassed and tempered.

 Advantageous embodiments of the device and the method according to the invention will become apparent from the dependent claims 2 to 28 and 30 to 34th

This allows e.g. grinding with a swash plate with fixed plate or two swash plates, conching with swash plates and as the last process step the tempering and crystallization by means of swash plates. Different arrangements of the swashplates can now lead to different variants of the device. Below are some examples.

In a first arrangement, the swash plates are arranged so that the lateral surface on the line from the cone tip to the transmission diameter are at each other, roll against each other without them rotating radially about its own axis. The swash plates are about cam which are connected via wobble shafts with the swash plates, caused to tumble and are also controlled. The Kurvenschelben can be performed both mechanically and servo-controlled. The swash plates are placed in a housing so that they are enclosed at the periphery. This creates a cavity between the swash plates. This cavity moves around the axis centers of the swash plates. The mass contained therein is therefore always around this fictitious axis between the

Axis center points led around. Is this fictitious axis horizontal and horizontal?

Cavity between the swashplates is a part of mass and the

Swash plates tumble against each other, the mass is pushed over the fictitious axis. When the movement is fast enough, the mass spills over. With this process, the oxygen exchange is promoted.

Especially at Conchen for the chocolate processing several factors are responsible for the rational conching. On the one hand, avoiding vomiting which can be reduced by means of shearing operations, then jacking is an essential process as well as a very important process of exchanging substances (for example dissolving and removing bitter substances). For this purpose, the swash plates are provided with geometries that show on the one hand shear effects, on the other hand promote the anointing. Furthermore, geometries can be used which specifically promote gas exchange. With the relationship of these geometries to

Volume of the masses to be processed is one of the advantages of this invention over the previous known systems. This makes it possible to shorten the conching time drastically, respectively, to be able to increase the quality of the mass with the same Conchierzeit. The shearing and anointing geometries are chosen so that they work as efficiently as possible, that is, have as little energy as possible. According to the invention is the intense overturning of the mass on the

Horizontal axis of the gas exchange optimized, as well as possible energy dissipation, which was supplied during shearing and anvil. Furthermore, it is easy to connect the swash plates to a heat balance, since the disks tumble and do not rotate. The high contact surface of the mass to be processed allows a gentle control of the heat supply and removal. These properties are also used for products such as in the chemical, pharmaceutical and cosmetics industry.

In a second arrangement, a swash plate is placed over a horizontal fixed plate. The swash plate wobbles over the fixed plate. Where the term fixed plate in this context must be understood so that it does not tumble. It can turn around its own axis and / or change its position. The swash plate is driven by a cam, in particular servo-controlled or driven. This makes it possible to leave the swash plate taumein so that together with the fixed plate a function for a mill (mill function) is formed. This arrangement has the advantage over many known systems that more parameters are available for adjustments. In addition to known settings such as peripheral speed of the rollers (fixed plate), friction, grinding gap, as well

Swashplate temperature (roll temperature) can be used pressure angle, gap angle and large and small speed differences. It is possible to let the fixed plate rotate such that the grinding material remains precisely in the working area, for example, by the centrifugal force. But this can also be achieved by the gap angle. This allows the regrind to remain in the mill until For example, a desired particle size is reached.

[011] In a third arrangement, the swash plates are as in [009]

described, however, exists between the lines on the lateral surfaces of Kegeispitz to the outer diameter a distance. In this enlarged space Mahlkörper or Kugein and ground material are filled. Due to the wobbling of the swash plates now the grinding media or balls and the material to be ground are forged. Compared to the conventional ball mills, however, the advantage is used here that more and controlled energy can be registered with the swash plates. Furthermore, it is possible modules with swash plates for subsequent

Coupling processing steps.

In a fourth arrangement, the swash plate is arranged similarly to [010]. However, the swash plate sits on a central shaft. The tumbling movements are driven by wobble push rods located close to the central shaft. The central shaft is coupled to the swash plate so that it can tumble, but is radially connected fixed. The swash plate can now for example be designed so that it also has scraping. It is now possible to run a "tabulation program." The mass is passed into the first chamber, dispensed, possibly further supplied with liquid chocolate mass via the radially disposed feed chamber, passed into the second chamber, and so on until the tempered, precrystallized mass is performed.

As a second possibility, the premixed seed crystals are conducted via the feed chambers into the tempering chambers, where they are processed intensively at a precise temperature. It is also quite possible to combine the two procedures. In both methods, the recycling of a portion of the mass, as in other systems, is not necessary, furthermore, it is also possible to add ingredients via the feed chambers.

Description of exemplary embodiments

The principle of the swash plate is explained with image sequence in FIGS. A, A1 to A8. By means of a simple gyroscope which rolls on the lateral surface around the tip of the cone, it can be clarified how according to the invention the wobble plate wobbles.

Fig. B shows two swash plates 1, which are connected to wobble thrust shafts 4, which in turn run on the cam right 3 and on the cam 2 left. The cams are arranged symmetrically.

Fig. C, C1 to C3 shows, in section and in the 3D view, how the swashplates, controlled by the cams, stagger against each other. Fig. D1 shows the structure for a conche with swash plates 1, swash plates with Versalbungskonturen negative 1.1, swash plates with Versalbungskontur positive 1.2, swash plate with shear contour positive 1.3, swash plate with shear contour negative 1.4. These are untergebraächt in a housing which consists of the housing shell 7 and the housing covers 8. The wobble thrust shafts 5.1 and 5.2 are embedded in the housing shell in this example. Outside the housing, the cams are right 3 and left 2, which drive the swash plates on the wobble thrust shafts 5.1 and 5.2.

Fig. D2 shows the housing with 5 pairs of swash plates.

Fig. D3 shows how the swash plates are stored in the wobble thrust shafts 5.1 and 5.2 6. Detail Y as a section of Fig. 6 shows the ball bushings storage.

Fig. E shows a housing as described in Fig. D1. It will be here

shown as two swash plates 1 is filled with a distance between the lines on the lateral surfaces of the cone tip to the outer diameter, the space between them with grinding media (balls) 9 partially, in which the material to be ground can be ground. Due to the tumbling movements, the grinding media are trimmed with the regrind. This walking now causes the grinding. An advantage of this method is that controlled energy can be added. It is possible, as shown here, more

Swash plates with Verbalbungskonturen negative 1.1, swash plates with

Oval contour positive 1.2, swash plate with shear contour positive 1.3,

Swash plate with shear contour negative 1.4 nachzuschalten, wherein the various processing contours on the swash plate can be combined with each other.

[030] FIG. F1 shows a swash plate 1 suspended from wobble shafts 4 and placed over the fixed plate 10. The wobble thrust shafts 4 are coupled to servo drives 34. The servo drives 34 are controlled by an electronic cam. Detail X shows a simplified representation of the ball bushings. The image sequence F2 to F5 shows the tumbling of the wobble cock over the

Fixplatte. G shows the same principle as described under Fig. F1, but the swash plate is in two parts. The swash plate top 13 is formed so that a swash plate tool 14 can be mounted. The fixed-plate lower part 11 is designed such that a fixed-plate tool 12 can be mounted.

This makes it possible to use different tools as required. The fixed plate with tool can be larger than the swash plate with tool.

As a result, ground material can be filled from outside. Through the central opening the ground material can be discharged.

Fig. H shows how a plurality of swash plates can be accommodated in a housing. The swash plate 15 is seated on a central shaft 16 and is coupled so that they tumble, but can not rotate radially about the central shaft 16. The wobble is effected via Taumelschubstangen 17. These in turn are moved over the cam flange 18. The swash plate 15 is arranged in the mass space 24 so that the line from the cone tip to the outer diameter is parallel to the upper fixed plate 25 and 19 and parallel to the lower fixed plate 21. The mass is directed into mass space 24 via mass inlet main flow 32. The swash plate 15 (can now be designed, for example, so that it also has Schabfunklion) mixes the mass and scrapes them from the fixed plate top and bottom. The central shaft 16 can be rotated. This is required for the scraping function. The top and bottom fixed plates can be moved over the heating / cooling channel 23 with the required temperature. Via the feed channel 27 and through the mass and ingredients inlet 26 liquid mass can be supplied. The processed or partially processed mass is via passages 28, located in the

Intermediate ring 30 are located between the mass spaces 24 forwarded. The individual mass spaces 24 are completed with the fixed plates top and bottom and the housing cylinder with supply channel 20 and separated with the intermediate plate 29. After finishing the mass, it is discharged through the bulk outlet 32. LIST OF REFERENCE NUMBERS
