Abstract

In the manufacture of fillings, the cutting of meat takes place in a special operating cycle, after which the cut mass is emulsified with additives contained therein, which process is completely independent from the cutting process. As a result, the degree of cutting can be regulated independently of the degree of emulsification. For example, it is possible to manufacture fillings with relatively long fibres in spite of extensive emulsification, which is not possible with known apparatuses, in which cutting and emulsification take place simultaneously. The emulsification takes place in an apparatus with a conical rotor (a) and a stator (b), the mutually facing surfaces of which are provided with grooves which drive the material forwards and promote turbulence and thus emulsification. The degree of emulsification can be regulated by changing the gap width between rotor (a) and stator (b). <IMAGE>

Description

Process and apparatus for processing solid,

edible material.

The invention relates to a method for processing most likely, edible Materials, especially meat and fillets, for cutting and emulsifying Substances contained in or added to the material, such as water and meat fat, and The invention also relates to zinc emulsifying apparatus for applying the method and dDin housing with an inlet opening, one concentric with this inlet opening Rotor and an outlet opening.

In the meat processing industry, the need exists to some extent Division, e.g. meat, which consists of protein, what-who and fat, and sometimes emulsification of water and fat in the same meat. There is probably a corresponding need in related industries in the production of solid, edible material.

up to now one was through the choice of, for example, a raw degree of division of meat is also bound to a high degree of emulsification of water and fat. Once in a while At the same time, with a high degree of fragmentation, there is also a high degree of emulsification he wishes. In many cases, however, it is desirable to use division and emulsification to be able to choose independently of one another, but this can be done with the methods known up to now and apparatus was not possible.

known apparatus for cutting and emulsifying meat for As far as known, fillings are all machines that cut and emulsify in Mix in one work step, and primarily with regard to the distribution of raw materials are set up. The emulsifying power is based on the known chopping machines on the variation of throughput time and hole size in the knives of the Hächsel machine cooperating perforated disks. At the same time Cut and emulsifying meat where the machines operate at high speeds, e.g. 3-4000 rpm, the meat fibers are cut very short and a high degree of emulsification becomes achieved. However, it is not possible to have the fiber length and degree of emulsification independent to choose from each other. Furthermore, with the known devices of the microcutter type, those with rotating Mcssern with rotational speeds of 1500-3000 rpm.

work, the risk that the knife set due to heat generation Idle is damaged and that the heat is transferred to the product to be treated becomes what worries veterinarians and responsible production people.

In addition to the aforementioned micro-cutters, so-called high-speed chippers are also known. which are provided with an armpit with scimitar-like knives, which are at knife speeds up to 4500 rpm. cut into a bowl shaped as a rotational body. These Machines work with high levels of noise and are also very expensive.

The purpose of the invention is to provide a method that enables the division of meat and other edible material to vary independently of the selected degree of emulsification of water, fat or other contained in the material, emulsifiable substances. Furthermore, it is the purpose of the invention to provide a relatively simple To instruct the emulsifier that is suitable for the process and that of the aforementioned Disadvantages of the known apparatus does not have.

The method according to the invention is peculiar in that the Breaking up the material, e.g. meat, and emulsifying it in the same material contained substances, e.g. water and fat, in two separate operations are executed.

Due to this, unknown within the meat processing industry, surprisingly simple procedures it is now possible to individually, e.g. proteins, Water, fat, divide and emulsify, making the one of the two operations is carried out with a certain degree of machining, regardless of the degree of machining of the second step. So you are able to produce fillings to control in such a way that a high degree of fragmentation is achieved, but without affecting one to be bound to a high degree of emulsification, as well as vice versa a low one Degree of division and a high degree of emulsification can choose.

A dividing unit can be used to divide the material rotatable knife or agitator elements are used that do not emulsify the product work at low speeds and pass the product through the dividing unit and drive it into the emulsifier.

Such an apparatus is disclosed in Australian Patent Specification No. 509,545 known. If the rotor in such a known unit with low Speed of rotation, a high degree of fragmentation can be achieved without emulsification the meat product can be achieved. and the degree of division and the capacity can be varied.

After the division, the material is put into a special emulsifying unit pressed, in which the degree of emulsification can also be varied, namely by changing the speed of rotation of the rotor and varying the width of the gap a material passage between the rotor wound and a stator forming the inner wall of the Apparatus housing forms.

The emulsifying apparatus according to the present invention is peculiar in that that the rotor is mainly conical and with its narrowest end towards the Inlet opening is mounted turning, and that its outside with close to each other lying, annular grooves is provided, and that the radial spacing conical housing inner wall lying from the rotor also with closely spaced, annular grooves is provided.

In a preferred embodiment of the rotor according to the invention are the grooves in planes at right angles to the rotor axis and each groove is interrupted, so that in fact a number of paragraphs distributed along the perimeter are formed. The opposite grooves on the inside wall of the housing are also interrupted. and cut like a screw thread.

The thread-like grooves push the material further forward. The interruption of the grooves partly ensures that the material does not is driven too fast and partly that turbulence occurs, which the emulsifying ability elevated.

Since the rotor and the stator forming the housing inner wall are mutually exclusive can be moved axially, the column width between them can be changed, whereby a change in the degree of emulsification is possible. The column width can be vary slightly if the stator with the conical inner wall with the apparatus housing is threaded so that it is a short or long distance in the direction of the conical rotor can be screwed. After the position has been set, the stator can be held in place by a locking arrangement.

The invention is described in more detail below with reference to the drawing explains, in Fig. 1 an embodiment for a system for exercising the inventive Process in the processing of meat to fillings shows, Fig. 2 an emulsifying apparatus for the application of the method according to the invention, and FIG. 3 shows a detail showing the shows interrupted grooves in the rotor.

The system shown in Fig. 1 has a feed hopper 1, at which Bottom a feed screw is placed, which is driven by a motor 7 via a transmission 9 is driven. The feed screw feeds a variable-capacity pump unit 3 with material, e.g. meat. The pump unit 3 pushes the material with adjustable variable capacity by a splitting unit 4, which in a known manner with Knives and interchangeable perforated disks are provided, so that perforated disks with different Hole sizes can be applied.

From the dividing unit 4, the material is transported by a conveyor 5 transported to an emulsifying apparatus 6.

Before the material is used, the emulsifying apparatus 6 is used for further processing leaves, fat and water are emulsified in the meat. The emulsifier 6 is driven by a motor 8.

In the emulsifier in Fig. 2, the meat that has already been cut and the remaining components of the filling at a predetermined speed, e.g. 8000 kg / hour, fed into the emulsifier housing (c), where a conical rotor a is provided, which is provided with pierced grooves in order to, inter alia, to form a large surface.

The rotor will adjust the meat to its own speed, because its grooves for the purpose of good grip and the turbulence and thus the To improve emulsification of the material (-Fig. 3) are interrupted. An encompassing one The conical stator b has a corresponding rotor on the side facing the rotor a Grooves that are, however, bevel cut (thread cut). This becomes the raw material Bring into the porcelain with the aid of centrifugal force.

In order to reduce this transport speed in an appropriate manner, the thread as well as the grooves in the rotor a have a suitable number of interruption points. These discontinuous grooves and threads are important factors for improvement emulsifying power, as they are highly asymmetrical. This serves two purposes: In part pulsation is prevented and in part the raw material is so powerfully mechanical influences that the result at least corresponds to the methods used today.

The rotor is driven directly by a motor d.

The stator b is by an external thread in a corresponding internal thread screwed into the housing c, thereby changing the gap width-between rotor and stator is possible with a view to varying the degree of emulsification. The setting the width of the column can be adjusted using a locking arrangement with a locking handle c to be recorded.

The following is one method of making meat fillings according to the present invention described.

The pre-shredded material, e.g. meat, bacon, spice, Water and other additives are used in, for example a mixer mixed, after which they are used in a well-known splitting unit such as the Australian U.S. Patent Specification No. 509,545, can be finely chopped. The now finished cut Material is caused by the pressure of the splitting unit to which it is located in the stator b located infeed opening of the emulsifying device transported.

The material flowing in through the stator b hits the rotor a, which runs at 3000 rpm. rotates and the material the material -with itself at the tip The specially shaped gripping surfaces located on the rotor are thrown into the periphery will.

Then practice the grooved, asymmetrically milled surfaces of the stator b and rotor a together, strong mechanical influence on the material. This effectively emulsifies fat and water together so that they come into contact such a consistency with the other additives that the filling is obtained then able to be cooked or fried without breaking the emulsion. The emulsified filling leaves the machine through the opening in the lower edge of the housing.

The emulsifying unit according to the present invention is through a Very low noise level and minimal operating costs excellent, there-none direct contact between rotating and stationary machine parts and therefore no Wear occurs. Furthermore, the degree of emulsification can be adjusted using a scale regulated, which simplifies the formulation of prescriptions. On top of that, the device is easy to clean and self-draining, which is why a possible Material congestion does not result in any local heat development in the filling material.

The invention provides an energy-saving apparatus, the one quality-improving effect on the filling, and an apparatus that works in the It is far cheaper to buy than conventional models.

The methods used so far, in which cutting and emulsifying done at the same time have the disadvantage that the meat fibers are cut short as they run at 3-4000 rpm. get cut. With the method according to the present In contrast to the invention, the fibers can be cut long (estimated 10-20 times longer than before), as the raw material is chopped with knives, which e.g. 125 rpm. and 8-16 t / h rotate.

This relationship between meat fibers and turns can one Ensure meat structure of previously unknown, good quality.

In order to preserve these long fibers in the finished product, it is important to that the degree of emulsification, among other things, with the help of the variable distance between the rotating and stationary parts of the apparatus can be varied so that the fibers are not cut through will.

Various modifications of the apparatus according to the invention can be made can of course be carried out within the scope of the invention.
