Separator for separating chopped food waste material

Abstract

A separator suitable for separating a dry chopped food waste material from a wet chopped food waste material, fed in the fluid state, is disclosed. The separator comprises an outer container (11) for an internal centrifuge consisting of a rotating cylinder (12) with perforated walls (13) in which a rotating screw feeder (14) is positioned for the advancement of the wet chopped food material and the separation of the liquid portion of the same, there also being an inlet opening (27) in the outer container (11) which receives the wet chopped food material to be introduced into the rotating cylinder (12) through a hollow duct (15) inside the screw feeder (14) which causes its upward movement and advancement, and an outlet opening (18) positioned near the top of the rotating cylinder (12) and outer container (11) which outwardly evacuates the chopped material without the liquid portion, wherein the outer container (11) consists of an upper half-shell (19) and a lower half-shell (20) provided with centering and sealing means (21) in correspondence with a coupling area, and the half-shells (19, 20) are monolithic and integral sanitation elements (23, 25) of the separator, a flow-regulation valve (34) being positioned in correspondence with a lower opening (33) for the evacuation of the liquid separated from the outer container (11).

Description

technical field [0001] The present invention relates to a separator suitable for separating dry chopped food waste from wet chopped food waste fed in a fluid state. Background technique [0002] In recent years and even now, various devices have been used for solid phase separation in the field of shredding and dehydration of food waste. [0003] These devices are located downstream of the assembly and affect the shredding of the food waste and the separation of the finely divided dry solids fraction from the wet chopped food waste fed in a fluid state. [0004] In general, some of the more widely used techniques can be divided into two main types. [0005] The first type is the so-called "pressure separator". These pressure separators consist of a screw feeder or screw that rotates within a fixed cylinder with perforated walls, the latter being located inside an external vessel to receive and contain the water separated by extrusion. [0006] The screw feeder receives a ...

Problems solved by technology

[0022] Furthermore, it is evident that inside the screw feeder / perforated cylinder set of centrifugal separators or inside the containment mechanism there are areas where self-cleaning operations are difficult and residues can build up, which also affects the integrity of the entire plant. health condition
