Abstract

Disposal of kitchen waste without problematic residues is possible by first comminuting the kitchen waste, then heating it to at least 100 DEG C, subsequently cooling it to room temperature and finally feeding it in a highly pasty to crumbly consistency to waste incineration.

Description

Die Erfindung betrifft ein Verfahren zur Entsorgung von Küchen­abfällen.The invention relates to a method for the disposal of kitchen waste.

Zur Zeit ist es üblich, Nahrungsmittelabfälle in mehr oder weni­ger frischem oder verdorbenem Zustand an Schweinemästereien zu liefern. Dabei werden der Küchenabfall aus Marmelade, Butter, Quark und Bechern sowie insbesondere Coca Cola- und Bierdosen separiert und der normalen Mullentsorgung zugeführt. Diese Arbeit ist aufwendig und wird von den Betroffenen nur ungern durchge­führt.It is currently common to deliver food waste to pork fattening farms in a more or less fresh or spoiled state. The kitchen waste from jam, butter, curd cheese and mugs, and in particular Coca Cola and beer cans, is separated and disposed of as normal garbage. This work is complex and is only reluctant to be carried out by those affected.

Die Verfütterung von Küchenabfällen an z.B. Schweinemästereien ist aus hygienischen sowie aus Seuchengründen problematisch. Dies gilt auch für eine Entsorgung auf normale Müllhalden, da es sich bei Küchenabfallen, die bei Gemeinschaftsverpflegungs-Küchen täg­lich in großen Mengen anfallen, nicht um sogenannten Haushalts­müll handelt. Dabei setzen sich die Küchenabfälle einerseits zu­sammen aus Nahrung smitteln wie z.B. Brot, belegte Brötchen, Kar­toffelschalen, Suppen und Soßen, Apfelmus, ganzen Salatköpfen, Porreestangen, Fleisch- oder Wurstresten, Dessertresten u.dgl. und andererseits aus Verpackungen, z.B. Plastikbechern unter­schiedlicher Größe, Milchtüten, Coca Cola-Dosen aus Aluminium, Kondensmilchdosen aus Aluminium u.dergl..Feeding kitchen waste to eg pig fattening is problematic for hygienic and epidemic reasons. This also applies to disposal on normal garbage dumps, since kitchen waste, which is generated daily in large quantities in communal catering kitchens, is not so-called household waste. The kitchen waste is made up of foodstuffs such as bread, sandwiches, potato peels, soups and sauces, apple sauce, whole lettuce sticks, leek sticks, meat or sausage leftovers, dessert leftovers and the like. and on the other hand from packaging, for example plastic cups of different sizes, milk cartons, Coca Cola cans made of aluminum, condensed milk cans made of aluminum and the like.

Zur Entsorgung von Küchenabfällen werden diese bisher lediglich zu einem "Kuchen" verpreßt. Dieses Verfahren stellt schon deshalb keine Lösung der genannten Probleme dar, weil weder der so herge­stellte "Kuchen" noch die abgepreßte Flüssigkeit steril sind und eine problemlose Entsorgung ermöglichen.To dispose of kitchen waste, it has so far only been pressed into a "cake". This method alone does not provide a solution to the problems mentioned, because neither the "cake" thus produced nor the liquid squeezed out are sterile and enable problem-free disposal.

Der Erfindung liegt die Aufgabe zugrunde, ein geeignetes Verfah­ren zur Entsorgung von Küchenabfällen zu entwickeln.The invention has for its object to develop a suitable method for the disposal of kitchen waste.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Kuchenabfälle zuerst zerkleinert, dann auf zumindest 100° C er­hitzt, anschließend auf Raumtemperatur abgekühlt und schließlich in hoch-pastöser bis bröckeliger Konsistenz der Müllverbrennung zugeführt werden.This object is achieved according to the invention in that the cake waste is first crushed, then heated to at least 100 ° C., then cooled to room temperature and finally fed to the waste incineration in a highly pasty to crumbly consistency.

Die zerkleinerten Küchenabfälle werden somit erfindungsgemäß zu­mindest pastörisiert, um sie für eine bestimmte Zeit haltbar zu machen. Wird die Erhitzung in einer druckfesten Anlage durchge­führt, kann auch eine Erhitzung auf über 100° C, z.B. auf 125° C und somit eine Sterilisierung der Masse erfolgen.According to the invention, the comminuted kitchen waste is at least pasteurized in order to make it durable for a certain time. If the heating is carried out in a pressure-resistant system, heating to over 100 ° C, e.g. to 125 ° C and thus sterilize the mass.

Soweit gewünscht kann nach der genannten Erhitzung der zerklei­nerten Masse aus dieser Feuchtigkeit herauskondensiert werden. Der Entfeuchtungsprozeß kann bis zu 30 min betragen und unter Vakuum erfolgen unter Zuhilfenahme eines Kondensators und einer Vakuumpumpe. Je nach Zusammensetzung des Abfalls kann aus der zerkleinerten Masse bis zu 40 % des ursprünglichen Gewichtes herauskondensiert werden.If desired, condensation can be condensed out of this moisture after the comminuted mass has been heated. The dehumidification process can take up to 30 minutes and take place under vacuum with the aid of a condenser and a vacuum pump. Depending on the composition of the waste, up to 40% of the original weight can be condensed out of the shredded mass.

Grundsätzlich ist es möglich, die Zerkleinerung und den thermi­schen Prozeß in getrennten Apparaten durchzuführen. Zur Verein­fachung der Handhabung und zur Verkürzung der Aufbereitungszeit ist es jedoch zweckmäßig, wenn die Erhitzung der Masse bereits während ihrer Zerkleinerung beginnt.In principle, it is possible to carry out the comminution and the thermal process in separate apparatus. In order to simplify handling and to shorten the preparation time, however, it is expedient if the mass begins to be heated as it is being comminuted.

Die Zerkleinerung der Küchenabfälle erfolgt vorzugsweise mit umlaufenden Zerkleinerungswerkzeugen, z.B. Messern, die eine ge­zielte Umwälzung der zu zerkleinernden Küchenabfälle bewirken. Dabei laufen die Zerkleinerungswerkzeuge z.B. mit 1.500 oder 3.000 U/min um.The kitchen waste is preferably shredded with rotating shredding tools, e.g. Knives that cause a targeted circulation of the kitchen waste to be shredded. The shredding tools run e.g. at 1,500 or 3,000 rpm.

Zur Unterstützung des Zerkleinerungsvorganges sowie zur Beschleu­nigung der Erhitzung der Masse ist es vorteilhaft, wenn die Ab­fälle während der Zerkleinerung und während der gesamten Er­hitzungsphase umgewälzt werden. Diese zusätzliche Umwälzung läßt sich durch einen Transportflügel erreichen, der erheblich langsa­mer umläuft als die Zerkleinerungswerkzeuge und die zu zerklei­nernden Abfälle bzw. die bereits zerkleinerte Masse von der Be­hälterwandung jeweils zum Zentrum lenkt.To support the shredding process and to accelerate the heating of the mass, it is advantageous if the waste is circulated during the shredding and during the entire heating phase. This additional circulation can be achieved by means of a transport wing which rotates considerably more slowly than the shredding tools and the waste to be shredded or the already shredded mass from the container wall to the center.

Da Küchenabfälle nicht sehr kompakt anfallen und somit ein hohes Volumen einnehmen, ist es zur Durchführung des erfindungsgemäßen Verfahrens vorteilhaft, wenn von den chargenweise aufzubereiten­den Abfällen in einer ersten Zerkleinerungsstufe nur die eine Chargenhälfte zerkleinert und dann in einer zweiten Zerkleine­rungsstufe die zweite Chargenhälfte in die vorzerkleinerte Masse hinzugegeben wird. Dabei reicht es aus, wenn in der ersten Zer­kleinerungsstufe die Zerkleinerungswerkzeuge mit etwa 3.000 U/min und für ca. 30 s umlaufen. Hierdurch erfolgt eine so hohe Ver­dichtung der Abfälle bzw. eine so große Volumenreduzierung, daß bereits nach ca. 1/2 min die zweite Chargenhälfte zugegeben wer­den kann. Hierdurch läßt sich die Kapazität des zum Einsatz kom­menden Apparates optimal ausnutzen. Dabei ist es zweckmäßig, wenn in der zweiten Zerkleinerungsstufe die Zerkleinerungswerkzeuge mit etwa 3.000 U/min und für ca. 1 min umlaufen.Since kitchen waste is not very compact and therefore takes up a high volume, it is advantageous for the implementation of the method according to the invention if, in a first shredding stage, only one half of the batch is shredded and then in a second shredding stage the second batch half is shredded into the pre-shredded mass is added. It is sufficient if in the first shredding stage the shredding tools run at around 3,000 rpm and for around 30 s. This results in such a high level of compaction of the waste or such a large volume reduction that the second batch half can be added after only about 1/2 min. In this way, the capacity of the apparatus used can be optimally used. It is useful if in the second shredding stage, the shredding tools run at about 3,000 rpm and for about 1 min.

Zur Verbesserung und insbesondere Verkürzung der Erhitzungsphase ist es zweckmäßig, wenn nach Beendigung der zweiten Zerkleine­rungsstufe und während der noch andauernden Erhitzungsphase die Zerkleinerungswerkzeuge einmal oder mehrmals kurzfristig umlau­fen.To improve and, in particular, shorten the heating phase, it is expedient if, after the second size reduction stage has ended and the heating phase is still ongoing, the size reduction tools circulate briefly once or several times.

Zur Erhitzung der Masse kann dieser die Wärme direkt und/oder in­direkt zugeführt werden. Dabei kann die direkte Wärmezufuhr durch Injizierung von Dampf in die aufzuheizende Masse erfolgen. Auf­grund der permanenten Umwälzung dieser Masse erfolgt die Wärme­abgabe an die Masse völlig gleichmäßig. Bei direkter Wärmezufuhr dauert die zweite Zerkleinerungsstufe einschließlich der gesamten Erhitzungsphase bis zu etwa 6 min.To heat the mass, the heat can be supplied directly and / or indirectly. Direct heat can be supplied by injecting steam into the mass to be heated. Due to the permanent circulation of this mass, the heat is given off to the mass completely evenly. In the case of direct heat supply, the second comminution stage, including the entire heating phase, takes up to about 6 minutes.

Die Wärmezufuhr kann aber auch indirekt erfolgen z.B. durch Elektrowärme mittels Heizmatten, durch Heißwasser, durch Wärme­trägeröl u.dergl. . Hierfür wird vorzugsweise eine die zu zerklei­nernden Abfälle aufnehmende Schüssel mit einem Doppelmantel ver­wendet. Bei indirekter Wärmezufuhr dauert die zweite Zerkleine­rungsstufe einschließlich der gesamten Erhitzungsphase bis zu etwa 30 min.The heat can also be supplied indirectly, e.g. by electrical heat using heating mats, by hot water, by thermal oil and the like. . For this purpose, a bowl with a double jacket is preferably used to hold the waste to be shredded. In the case of indirect heat supply, the second crushing stage, including the entire heating phase, takes up to about 30 minutes.

Bei dem erfindungsgemäßen Verfahren ist es vorteilhaft, wenn die Abfälle aus Nahrungsmitteln auf eine Stückgröße von etwa 2 - 3 mm zerkleinert werden, und wenn die Abfälle aus Verpackungen auf eine Stückgröße von etwa 10 mm zerkleinert werden. Dabei ist es möglich, die aus Nahrungsmitteln herrührenden Küchenabfälle ge­trennt von den aus Verpackungen herrührenden Küchenabfällen zu­zuführen. Der Vorteil des erfindungsgemäßen Verfahrens liegt aber darin, daß eine derartige Trennung nicht erforderlich ist. Wäh­rend der Erhitzungsphase nehmen die auf Stückgrößen von etwa 2 bis 3 mm zerkleinerten Abfälle aus Nahrungsmitteln eine mus­artige Konsistenz, während die Verpackungsanteile kleiner oder gleich 10 mm sind.In the method according to the invention, it is advantageous if the waste from food is shredded to a piece size of about 2-3 mm, and if the waste from packaging is shredded to a piece size of about 10 mm. It is possible to feed the kitchen waste from food separately from the kitchen waste from packaging. The advantage of the method according to the invention lies in the fact that such a separation is not necessary. During the heating phase, they take on piece sizes of about 2 to 3 mm shredded food waste has a musky consistency, while the packaging content is less than or equal to 10 mm.

Nach Abkühlung auf Raumtemperatur liegt die Masse als hoch­pastöser bis bröckeliger Kuchen vor, der sich einfach handhaben, ggf. bis zu zwei Wochen sammeln bzw. zwischenlagern läßt um dann der Müllverbrennung zugeführt zu werden z.B. über Sammeltranspor­te. Durch die erfindungsgemäße Aufbereitung der Küchenabfälle läßt sich eine Volumenreduzierung bis zum Achtfachen erreichen.After cooling to room temperature, the mass is in the form of a highly pasty to crumbly cake that is easy to handle, can be collected or temporarily stored for up to two weeks, if necessary, so that it can then be incinerated, e.g. via groupage. A volume reduction of up to eight times can be achieved by the preparation of the kitchen waste according to the invention.
