Definitions

  • the invention relates to a method for separating food from its packaging, in which the separation is carried out by pressing through a sieve, and a device for carrying out this method.
  • the foodstuffs in question are those that have been made during production, that have passed their expiry date, or that were introduced, although they are not marketable under German regulations. Foodstuffs are also suitable for which no expiry dates are specified, but which are no longer marketable due to storage for too long, storage under incorrect conditions or other circumstances.
  • a method for handling bulk goods filled in sacks in which the sacks are opened, torn and the torn sacks be separated from the bulk material.
  • the device belonging to the method comprises a comminution screw for opening and tearing the sacks and conveying the mixture of bulk material and bag parts onto a conveyor belt or directly into a separating device, where the bulk material falls through a sieve and the bag parts are discharged separately.
  • the method according to FR-A-2 356 585 is limited to bulk goods packed in sacks and is not suitable for foodstuffs that are not pourable and in particular pasty or viscous, since the separation takes place only by the action of gravity on the goods on the sieve.
  • a device for separating the flowable constituents from a mixture of such and solid, in particular for preparing foods is known.
  • a known press passing machine is used with a press belt which is partially wrapped around a perforated drum and can be pressed onto this by means of a press roll.
  • the perforated drum By forming the perforated drum with a non-perforated central zone and feeding the material to be treated into the area thereof, the separation process can be improved.
  • the material to be treated can consist of a meat-tendon / bone mixture, for the production of sausages or, for example, incorrect packaging resulting from cheese or butter packaging.
  • a disadvantage of the device according to DE-C-36 33 396 is that it is not suitable for shredding conventional food packaging.
  • the object of the invention is to find a method for the mechanical processing of the foods mentioned, which is not only easy to carry out with relatively little mechanical means, but which it also allows the processing of various types of food, the amount of food still adhering to the packaging remnants being said to be insignificantly small.
  • the method according to the invention is also intended to be used for processing non-packaged foods, e.g. Sausages in natural casings or bread without packaging are suitable, with the packaged food being so well separated from packaging and food that they can be used as animal feed.
  • non-packaged foods e.g. Sausages in natural casings or bread without packaging are suitable, with the packaged food being so well separated from packaging and food that they can be used as animal feed.
  • This object is achieved in that the food with the packaging is crushed by squeezing and formed into a strand and the strand is cut for further crushing before pressing.
  • superheated steam can advantageously be introduced into the comminuted mass before pressing.
  • the device for achieving the object according to the invention is advantageously characterized in that it has a comminution twin screw, a rotating multi-blade knife and a screen press.
  • the hard-packed foods and solid foods are crushed in a pre-shredder 12 by means of an electrically driven, counter-rotating shredding twin screw 1 with square helices, the packages being torn open and solid foods being roughly shredded.
  • the comminuted mixture is then comminuted again as a quasi-homogeneous mass after passing through a plate with openings 11 by a multi-bladed knife 2.
  • the mass is then fed to an electrically driven screw conveyor 4, in the beginning of which foods with soft packaging can also be entered.
  • the screw conveyor 4 throws into an input hopper 9 with an electrically driven conveyor wing 10. At this point, hot steam can be added to better separate the food from the packaging.
  • the mass is then placed in a screen press 3 and there continuously between an electrically driven screen drum 5 and a separately electrically driven one Pressure band 6 is squeezed so that the foodstuffs are pressed separately from the packaging through the openings of the drum 5, while the packaging means are retained on the outer wall of the drum 5.
  • the packaging residues are removed from the outer wall of the drum by an outer scraper 7. removed while the cleanly squeezed food is recovered from the inside of the open-sided sieve drum 5 by means of an externally attached inner scraper 8.
  • the method can therefore be carried out with simple means without an energy-intensive leaching.
