    Abstract: A foreign matter removing apparatus for removing foreign matter in a powder and granular material is provided. The foreign matter removing apparatus includes: a conveyance device configured to convey the powder and granular material from a supply port to a discharge port that are for the powder and granular material; and a foreign matter sedimentation device that is provided between the supply port and the discharge port on a conveyance path of the conveyance device, and is configured to sediment the foreign matter in the powder and granular material. The foreign matter sedimentation device includes both a foreign matter discharge port provided at a lowest position in a height direction and a bottom inclined toward the foreign matter discharge port.

    Abstract: A method for fractionating a milled grain product into coarse and fine fractions includes providing a sieving apparatus with a bottom chamber divided from a top chamber by a sieve, an inlet port in the top chamber, a top chamber cover defined by a plurality of openings, and a first exit port in the bottom chamber, and applying vacuum suction to the sieving apparatus. The vacuum suction is configured to draw grain particles through the inlet port into the top chamber, generate substantially horizontal airflow in the top chamber via the inlet port; and generate substantially vertical airflow in the top chamber via the plurality of openings, wherein the substantially horizontal airflow and the substantially vertical airflow combine to generate turbulence which fluidizes the grain particles in the upper chamber and prevents blockage of the sieve; and drawing fine grain particles through the sieve and out of the bottom chamber via the first exit port under the vacuum suction and collecting a fine grain particle fraction.

    Abstract: There is disclosed a method and apparatus for separating stones, fibers and plastics from biodegradable material. In an embodiment, the apparatus comprises: an inclined trough having a feed entry at a top end for receiving the feed material, the inclined trough including a plurality of riffles angled to at least partially hinder and unsettle a flow of the feed material flowing down the inclined trough; one or more vibratory motors configured to induce a vibration in the inclined trough; one or more blowers configured to generate an air flow through overhead air vent nozzles positioned over the inclined trough and directing the air flow to one side of the inclined trough; and a material resilience separator for separating the contaminants from the biodegradable materials in the remaining material.

    Abstract: A classifying fluid bed granulation unit includes a perforated bed floor; a fluid bed section; a solid feed inlet or internal crushing device; a fluidization air inlet; a liquid solution or melt feed inlet and nozzles; an air outlet; and a product outlet; wherein the fluid bed section comprises at least one particle classification element comprising one or more vertically inclined channels having top and bottom end feed openings, and wherein the one or more vertically inclined channels have upper and lower side slots. In operation of the above fluid bed granulation unit, each channel of the element is separating particles into large particle and small particle fractions and transporting the large particle fraction upwards and the small particle fraction downwards in each channel, and the large particle and small particle fractions are transported out of the upper and lower side slots, respectively.
