Provided are a silver powder having powder physical properties enabling reduction of volume resistivity after firing and a method of producing this silver powder. The silver powder has a tap density of 4.8 g/mL or more, a TAP/D50 value (value determined by dividing the tap density (g/mL) by the volume-based median diameter (?m)) of not less than 7 and not more than 15, and a specific surface area of not less than 0.75 m.sup.2/g and not more than 1.3 m.sup.2/g.

A hazelnut processing plant provides separation of unshelled hazelnut as shell and as decorticated hazelnut by means of breaking the shells thereof. The hazelnut processing plant includes at least one calibration sieve where the unshelled hazelnut is transferred in order to be categorized in accordance with the dimensions thereof, at least one calibration line which has at least one each calibration silos for each category of the unshelled hazelnut separated according to dimensions in said calibration sieve, at least one stone, where the unshelled hazelnut is transferred in order to be separated from the shell thereof, at the continuation of said calibration line, at least one charger sieve which can separate the hazelnut broken at said stone by sieving the dust of said hazelnut, at least one breaking line, which has at least one ventilator in order to provide separation of decorticated hazelnuts, shells and creased hazelnuts.

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.

A system for processing usable crop intermixed with debris and having a frame with a conveying system thereon. The conveying system has a first debris separating assembly with a first subframe having a plurality of cooperating rollers that are configured to cause separation of debris from the usable crop, A second debris separating assembly, different than the first debris separating assembly, has a second subframe with a plurality of cooperating rollers thereon that are configured to cause separation of debris from the usable crop. The frame and first and second debris separating assemblies are configured as overall like modules so that the first and second debris separating assemblies can be separately operatively connected, one in place of the other, on the frame.
