DE19539247C2 - Device for treating pieces of meat - Google Patents

Description

The invention relates to a device according to the preamble of Claim 1 Under the term "meat" is red or white meat, poultry, fish or such meat products containing components understood.

Such a device is known from SU 891 047. At this known device is a liquid-tight ver lockable, polygonal drum, which is used to hold the Pieces of meat - for example for pickling - are used in rotation offset, massaging the meat through the corners of the container when it rotates. The treatment The meat is intensified by the fact that the container ter is supported with eccentrics on rollers, so that when rotating supply of the container due to the eccentric a vertical stroke movement or swinging movement of the container becomes.

There are also generic devices, for example known from DE 31 38 995 C2 or from EP 391 492 A1.

These known generic arrangements have rivers liquid-tight containers, which are filled with a brine and serve to hold the pieces of meat. A beef action takes place by mechanical stirring or kneading the pieces of meat by either verse one with a spiral the stirring rod is immersed in the fixed container or by spiraling the container itself on its inside trained kneading blades, wherein a rotation of the  slanted or lying container with the pieces of meat Help the kneading wings lift out of the lake and out of relative high altitude into the lake.

In both known devices, the treatment of Meat through relatively slow rotating movements prevent damage to the meat. The single ones Impulses that are imparted to the meat are given by Be movements of the meat over several centimeters or deci meters reached.

To facilitate the penetration of the brine into the pieces of meat, the known containers are evacuated. During treatment The meat generates a considerable amount of heat in the container must be dissipated.

A disadvantage of the known containers is that the containers require a great deal of constructive effort in the face of the rotational movement of either the container or the Be sufficient immersion in the agitator guarantee for evacuation. A rotatable container ter requires additional design effort to a Küh to allow the container to develop. Arranged firmly in the container Kneading blades make cleaning the inside of the container difficult.

Due to the considerable intensity of the individual impulses at gat appropriate and also the aforementioned generic Devices cannot damage the meat close, such damage in the form of Fa serum detachments or fat detachments occur. This replaced Components make cleaning the containers difficult and can by clogging the inlet or outlet openings the ord appropriate operation of the known devices other.

The invention has for its object a generic To improve the device so that this is both a is structured professionally and inexpensively as well as a gentle one Treatment of the pieces of meat allows.

This object of the invention is based on the features of the spell 1 solved. The sub-claims 2 to 8 shape the subject according to claim 1 further.

In other words, the invention proposes instead of Im pulse with high amplitude and low frequency impulses with a comparatively high frequency, however reduced amplitude to use. The invention starts from the consideration that such pulses with low ampli tude the meat pieces sparingly, so that the disadvantageous injury tongues of pieces of meat can be avoided. The he Increasing the pulse frequency causes an intensity of the meat treatment that with the treatment intensity in the known  Devices is comparable, so that no longer overall Treatment times are required and the device has the same productivity as known devices.

As vibrators come electrodynamic, electro motor, piezoceramic or other elements in question. These can be arranged on the outside of the container, like this is known for example from vibrating motors.

However, the damping effect of the container wall can ver be avoided if the vibrators are in the container Neren are arranged so that they with the help of the Lake can act as a transmission medium on the pieces of meat and a more direct energy input into the pieces of meat enable.

The vibration generator (s) can be used as immersion elements be trained outside the container in a rest position are arranged and the if the container with brine and Pieces of meat is filled, immersed in the interior of the container will. In this way, the container wall can be smooth-walled be trained and the container interior can be used for loading send or empty and freely accessible for cleaning be.

The vibration frequency used depends on the treating meat (red meat, white meat, Ge wings, fish or products made from such meats exist or contain them) as well as device-specific parameters ter and can range from 30 Hz to the ultrasonic range lie.

Mixing of the pieces of meat can be provided to ensure even processing of all pieces of meat allow and shadowing from badly "sonicated" or to compensate for "irradiated" areas. One can be advantageous  such mixing arrangement without moving components be formed from nozzles that circulate and through the brine their arrangement cause the contents of the container to move, so that all pieces of meat evenly vibrate be exposed to impulses.

The vibrators themselves can also be used to Mixing the pieces of meat can be used and in the manner of a Vibratory conveyor to transport the pieces of meat. If necessary, this support effect can be shared with the mentioned nozzles are combined so that the intensity of the Nozzles can be kept low and one if possible great protection for the pieces of meat.

According to the invention, the meat is treated gently pieces possible because only small amplitudes act and mechanical influences, such as kneading hooks, kneading wings or the like are known for the introduction of the machining tion impulses are not necessary and at most for through Mix the pieces of meat can serve. Accordingly can be a shredding of the pieces of meat, a detachment of Fat components as well as foaming within the loading be avoided.

The design effort of the device is comparative low, since no drive and no bearings for one rotate the container or rotating agitators are necessary. The Container shape can be chosen almost arbitrarily and that accordingly inexpensive, for example as a cylindrical Component are manufactured. Sealing the container for the Evacuation can be done easily because there is no through guidance of rotating parts is required. Spiral, spiral shaped or helical agitators or kneading plates can be dispensed with in a cost-saving manner.  

The container inner walls can be smooth, so that time-saving cleaning with very good cleaning results nissen is possible.

The cooling of the fixed container can be done easily and be carried out inexpensively.

The control effort for operating the device can can be simplified because there is no motor control for one turn drive of the container is needed.

The container can be either fixed and be loaded by baskets, with inlet and outlet pipes for the brine for filling or emptying the container are provided. Alternatively, the container can also be tiltable so that the emptying of the container can be done by the tilting movement.

To the vibrations generated to treat the meat not dampen pieces unnecessarily and in the interest of one as little noise as possible the entry of The container can reduce structure-borne noise in the building be freely swinging, e.g. B. on rubber blocks or hanging.

With the device designed according to the invention due to the gentle hydrodynamic treatment sorts of meat, fish or poultry are treated.
