Definitions

  • the invention relates to a method for the disposal of kitchen waste.
  • 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.
  • the invention has for its object to develop a suitable method for the disposal of kitchen waste.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the size reduction tools circulate briefly once or several times.
  • 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.
  • the second comminution stage including the entire heating phase, takes up to about 6 minutes.
  • the heat can also be supplied indirectly, e.g. by electrical heat using heating mats, by hot water, by thermal oil and the like. .
  • a bowl with a double jacket is preferably used to hold the waste to be shredded.
  • the second crushing stage, including the entire heating phase takes up to about 30 minutes.
  • 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.
  • the mass 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.
