Apparatus for shredding food waste including bones

Abstract

Device for disintegrating food waste, comprising bones, at a machine for cutting vegetables using a rotating disc (1) provided with an opening (2) in the disc and a knife (3) arranged by and along the opening (2), which cutting disc (1) is mounted on a driven vertical axis (19), and wherein the cutting disc is arranged in the lower part of a cylindrical housing (18) into which food leftovers are arranged to be fed down from above the cutting disc. The invention is characterised in that a stationary stopping means (5) is mounted above the cutting disc (1) and from the center (16) of the cutting disc to the periphery (17) of the cutting disc, in that the stopping means (5) extends a certain distance upwards from the cutting disc, in that the stopping means (5) has a stopping surface (8), facing in a direction opposite to the direction (9) of motion of the cutting disc (1), in that the angle (V1) between the edge (4) of the knife and the stopping surface (8) in a rotational position of the cutting disc (1), in which the edge (4) of the knife and the stopping surface (8) partly overlap as seen in a direction perpendicularly to the plane of the cutting disc (1), opens inwards towards the center(16) of the cutting disc, and in that the vertical distance between the edge of the knife and the underside of the stopping means allows cutting of bones, but is less than about 1 millimeters.

Description

technical field [0001] The present invention relates to a device for shredding food waste including bones. Background technique [0002] In the kitchens and restaurants of the public catering industry, a large amount of food waste is generated. Food waste is usually separated during dishwashing. Advantageously, the leftovers are shredded and fed into a collecting tank. An advantageous way of transporting the leftovers is to suck them out of the collection tank and into a truck for removal. [0003] An increasingly common way to dispose of leftovers is to ship them to biogas manufacturing plants, where they are turned into biogas for use as vehicle propellant. [0004] In order to send the leftovers to the collecting tank, the leftovers must be shredded so that they can be conveyed in the pipes without clogging. This is especially true for bones of poultry, fish, and other kinds of bones such as ribs. Furthermore, it is advantageous for the biogas production plant that t...
