DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
It is known to provide sausage with a spice coating on the outside, for example pepper salami. For this purpose, the sausage is freed from the casing and, after coating with an adhesive liquid, is covered with the ground spice in an airstream (DE-A 31 35 493). Since this process is laborious, it has also been proposed to provide the sausage casing on the inside with an edible coating which contains the spices (DE-A 41 23 745, EP-B 408 164, DD-A-140 196, Chemical Abstracts JP 49075746, JP 3010660 Abstract, JP 52070039 Abstract). However, in this process the spice becomes part of a relatively thick binder layer containing the spice, which binder layer remains on the sausage after the casing has been removed. This impairs the appearance of the sausage in comparison with conventional products, for example pepper salami. It is also undesirable if the spicecontaining coating including spices is removed from the sausage together with the sausage casing. The production of the known spice-containing sausage casings is also relatively laborious.
EP-B-408 164 discloses providing the sausage casing on the inside with spice particles, by providing the inside with an adhesive layer and dusting the spice particles onto this adhesive layer. Only the treatment of planar casing material is disclosed, tubular material must be cut open in advance.
It is a further disadvantage that the casing material, when the sausage ends are tied off by means of a cord or wire clip, is subjected to great stress, which can lead to tearing of the same if a sharp spice fragment is situated on the inside at the tying-off point.
SUMMARY OF THE INVENTION
The object underlying the invention is to provide a device of the type mentioned which permits tubular sausage casings with an inner spice coating to be produced.
The device according to the invention provides that the spice particles are projected against an adhesive coating which has been applied to the inside of the sausage casing. The spice particles remain on, or partly in, the adhesive coating and are permanently joined by this means to the sausage casing, as soon as the adhesive layer has dried. The sausage casings produced in this manner can be processed conventionally.
The device according to the invention has the advantage that it succeeds with only slight modification of known sausage casing manufacturing devices, for devices are known which are used to provide endless fabric tubings with a collagen coating on the inside which converts the fabric into a sealing skin. The internal collagen application can, while it is still sufficiently adhesive, be used to bind the spice particles to the sausage casing. For this purpose, downstream of the coating apparatus, there is provided an apparatus which projects the particles against the inside of the inflated sausage casing. This is performed, for example, by means of a thrower disc or a blast nozzle. The fabric tubing material can be run over the coating apparatus and thrower apparatus in a conventional manner. The adhesive coating is then allowed to harden. Generally this means that it is allowed to dry. However, it is not intended to exclude the fact that it can be hardened by other processes, for example chemical processes.
Expediently, the radial velocity for applying the spice particles to the sausage casing is imparted to the particles by a blast nozzle or thrower disc, by means of which a readily controllable application of the spice particles may be achieved.
According to the invention, the particle coating may be interrupted in the sections destined for tying off individual sausage casings. This prevents an excessive stressing of the casing material, which can lead to tearing of the same if a sharp spice fragment is situated on the inside at the tying-off point. In the process according to the invention, in the sections predetermined for tying off individual sausage casings, the particle feed is interrupted in sections during the covering of the inside of the sausage casings. Alternatively, it can be pr
