Abstract: 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.

Abstract: A pre-cleaning system is provided. The pre-cleaning system is for providing purification of unshelled hazelnut at least partially from foreign substances before processing of unshelled hazelnut. The improvement of the pre-cleaning system is that the pre-cleaning system includes at least one first separation unit where the foreign substances, which are outside the acceptable dimensions of unshelled hazelnut, are sieved and separated, at least one second separation unit positioned in the vicinity of said first separation unit and which can provide separation of foreign substances, which have specific weight lower than the specific weight of acceptable unshelled hazelnut, by means of an artificial air flow provided in at least one flow path provided thereon, at least one third separation unit positioned in the vicinity of said second separation unit and which can provide separation of foreign substances, which have specific weight higher than the specific weight of unshelled hazelnut.
