Process and device for producing packaged foods with smoked flavour

The invention relates according to the preamble of claim 1 is a method for producing packaged foodstuffs with Smoke flavor, in particular sausage, wherein prior to filling of the packaging mate Kung good on the inner surface of the packaging material a liquid smoke Coating is applied, as well as a device for implementing this Process.

Smoked foods in sausage form can in various ways be prepared: In probably the oldest methods are the life medium, z. B. sausage meat for sausage or cheese, in a gas-permeable shell. In a smoke chamber the packaged food is exposed to smoke, the can penetrate into the food through the shell. is Newer methods Liquid smoke used by the gas-permeable packed foods sprayed or its both liquid and gas permeable packaging is impregnated material (EP 0121294 A2), so that it then also in the Food can penetrate. It is also possible to the packaged food in immerse liquid smoke. Here, however, the dosage is difficult and the subsequent drying process very costly.

stick the mentioned methods, individually or together various disadvantages at which impede the manufacture of foodstuffs with smoke flavor or expensive. For example, special smoke chambers are needed, in which the ver prepacked food is exposed to smoke or sprayed with it. In the event of diving is a plunge pool needed and it is a complicated Trock tion process required. There is an additional, substantial disadvantage of throughout the prior art: In all the known method, the casing must be gas-permeable, so that the (liquid) smoke from entering the food may, with the result that the Haltbarbeit of the packaged food Example is somewhat limited because of potentially invading germs. can also the food to dry out slightly. This can in the current state of the art only be countered by a second, gas-tight packaging.

It is further known from US 5,484,001, prior to filling a packaging mate kung case u with sausage meat. like. this to coat the inside with liquid smoke. Put this process and the envisaged for its implementation device but a packaging wrapper in the form of a closed except for a filling opening Container, advance in the form of a bag. Therefore, the coating may only intermittently carried out, and both the methods known for this purpose as well as the proposed device are unsuitable for a continuous process.

In addition, the coating thickness can not be originally dosed, because they not only on the amount introduced, but also on the pressing force of the Role and the film thickness of the pouch depends. The result is a different order quantity and therefore inevitably different Strength of the smoke flavor, assumed by the contents.

It is therefore the object underlying the invention, ways and means to Make available, with which food with smoke flavor certain intensity in a simple and inexpensive way and continuously produced leave.

According to the invention the solution of this problem according to claim 1 in a Ver drive, in which the front of the pouring of the packaged product on the inner surface Packaging material, a liquid smoke coating is applied, and which is characterized in that the liquid smoke bandförmi on first applied ges packaging material and then the packaging material is closed to form a tube, which is finally filled with filling material.

After filling the envelope that comes with smoke flavor to provided Foods with the liquid smoke into contact, so that it in the food can diffuse. In this method, uniform coating is the Packaging material therefore relatively simple and safe because it for Beschich th is stretched flat.

The shell may consist of gas- and liquid-impermeable material, which brings significant benefits that the packaged alone with the shell Food is already protected against the penetration of germs and thus longer is liable and also can not easily dry out.

The inventive apparatus according to claim 4 with a the tubular goods to be packaged leading fill tube and means for applying the liquid smoke coating on an area of ​​the packaging material is characterized in that coaxially with the outlet opening of the filling tube, a band-shaped packaging material at a the filling tube concentrically surrounds tube forming and the outlet opening provided through promotional tube forming station and this immediately a Coating station upstream.

The invention will be explained based on the drawing now, which in longitudinal section of a device for producing sausage-like foodstuffs with smoke taste shows in the first band-shaped packaging material with Flüssi is grauch coated and optionally drying the liquid smoke layer before the Packaging material is processed and filled the tube.

Some components of these means are conventional in the prior art: a filling pipe <b>10</b>, Which at its front end of a tubular sausage casing <b>12</b> surrounded; an end<b>14</b> the sausage casing <b>12</b> finds itself faced with the outlet opening <b>16</b> the filling tube <b>10</b> and is using a clip <b>18</b> closed; between tween the tubular sausage casing <b>12</b> and the filling tube <b>10</b> is short in front of the outlet opening <b>16</b>, An inner casing brake <b>20</b>While an outer intestine brake <b>21</b> is arranged in the direction of it.

For filling the sausage casing is filling through the filling tube <b>10</b> pressed and enters from the outlet opening <b>16</b> out. It fills the blank at the beginning of the sausage casing<b>12</b> and moved with increasing filling them further sausage casing from a buffer stock <b>22</b> against the resistance of the skin brake <b>20</b> and <b>21</b> so long after until a sausage of the desired length is filled. Then the filling process is under broken, a partial length of the sausage casing <b>12</b> by compressing and Verschlie KISSING divided and from the rest of the sausage casing <b>12</b> separated. Simultaneously, the in front of the outlet opening <b>16</b> located end of the sausage casing <b>12</b> closed so that produces the following sausage in the same way as the previous can be.

The essential difference from the prior art consists in the in the drawing depicted sausage casing <b>12</b> that it on its inner side <b>30</b> is coated with liquid smoke, was applied until shortly before filling. The coating the case inside <b>30</b> serving coating station <b>31</b> has a storage pool <b>32</b> to which liquid smoke <b>34</b> is filled. In the storage tanks <b>32</b> is an applicator roll <b>36</b> arranged, which partly in the liquid smoke <b>34</b> dips. Compared to the application roller<b>36</b> There is a backing roll <b>38</b>, Further, a drying apparatus<b>40</b>, For example, the form of a heat radiator has provided. There are also a form shoulder<b>42</b>, A welding station <b>44</b> and a conveyor <b>46</b>Which together form a Tube formation station <b>41</b> form.

The tubular, coated with liquid smoke sausage casing <b>12</b> is in the mapped device from first band-shaped flat film <b>48</b> produced. This flat film <b>48</b> continuously from a film roll <b>50</b> peeled and between tween the applicator roll <b>36</b> and the backing roll <b>38</b> passed. there circulated the application roller <b>36</b> on one side of the flat foil <b>48</b> from and wets with liquid smoke. The flat film<b>48</b> will continue with their Benetz with liquid smoke th page on the drying device <b>40</b> passed so that the liquid smoke Coating on the flat film <b>48</b> is dried. Subsequently, with the dried liquid smoke coating provided flat film <b>48</b> the forming shoulder <b>42</b> fed, where the flat film <b>48</b> is molded to the hose by the two Film edges are brought together. The two film edges are subsequently ßend in the welding station <b>44</b> welded to each other, so that finally a the sausage casing <b>12</b> fine, dense tubing arises, the inside with liquid is smoke coated.

The straight welded sausage casing of the conveyor <b>46</b> in the Puffervor advice <b>22</b> promoted. It constantly is flat film<b>48</b> followed suit and by the film roll <b>50</b> handled.
