The invention is directed to a method for the electrostatic separation of foodstuff components present in a foodstuff composition by an electrostatic separator, said separator comprising a separation chamber and at least three plate electrodes positioned in the separation chamber, wherein the plate electrodes are positioned substantially parallel and are spaced apparat from adjacent plate electrodes; the plate electrodes are arranged to be rotated alternately around a first and a second rotation axis, which rotation axes are substantially parallel, provided at a distance from each other and substantially perpendicular to the plate electrodes; at least part of an outer surface of the plate electrodes faces at least part of an outer surface of adjacent plate electrodes; a flow path for a stream of foodstuff components is provided between the outer surface parts of adjacent plate electrodes which are facing each other; and the plate electrodes are alternately chargeable with a positive and a negative electric charge or alternately grounded and either positively or negatively chargeable.

A method and system for air classification of a milled feed stock includes generating a feed stream by combining the milled feed stock with at least one gasflow element, wherein the milled feed stock includes a plurality of particle sizes. The method and system includes directing the feed stream across a curvilinear surface, such that the milled feed stock in the feed stream separates into a plurality of classification streams, each of the plurality of classification streams based on the particle sizes of the milled feed stock. Therein, the method and system separates the plurality of classification streams and collects each of the plurality of classification streams, thereby classifying the milled feed stock contained therein based on the particle sizes for each of the plurality of classification streams.

The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

An electrostatic separation device (is for a mixture of granules of different materials. The device includes a separation chamber having an inlet and delimiting an inner volume and a collection device for granules placed in the inner volume, opposite the inlet. At least two pairs of electrodes are successively placed in the elevation direction in the inner volume, between the inlet and the collection device. Each pair includes an anode and a cathode, placed on either side of a central axis extending in the elevation direction. At least one generating system is suitable for applying a difference in electric potential between the anode and the cathode of each pair.

Described are microparticle fractionating apparatus and methods of fractionating microparticles. Multiple electrodes may be used to charge droplets when separating and collecting microparticles based on a result analyzed by an optical methodologies. A first electrode may be used to charge a sample fluid, and a second electrode used to apply additional charge near a droplet break-off point.

A system for eliminating unexploded ordnance from a mixture. The system includes a separation plant, including a crusher, a magnetic separation station, and a screen plant. The crusher reduces the size of pieces in the mixture, the magnetic separator separates pieces containing a significant amount of ferrous metal, and the screen separates small pieces from larger pieces. The fine output of the screen is composed of pieces that are sufficiently small to pose little hazard; they may be further subjected to heat treatment. Large pieces containing ferrous metal, or large pieces containing nonferrous metal, may be explosive and are transported, using an unmanned machine, to an inspection plant where they are sorted and where any unexploded ordnance is identified and disposed of. The separation plant is sufficiently distant from the inspection plant that an explosion at the separation plant does not pose a hazard to personnel at the inspection plant.

A tribo-electrostatic separation process for fractionating a feed mixture derived from dried distiller's grains (DDG) or distiller's dried grains and mixed with solubles (DDGS) is disclosed.

An improved belt separator system and an improved method to separate particle mixtures based on triboelectric separation of particles is disclosed. The separator system includes a tensioning system embodying a tension roller and a two-part rotating shaft assembly.
