Calibrating and cracking hazelnuts
Profit from our know-how in nut processing and increase your productivity in all processes.
Calibrating and cracking hazelnuts.
Sort the hazelnuts by size and break the outer shell.
To extract the valuable hazelnut cores, the hard shell is cracked. Cracking machines or combined calibration and cracking machines are used. The machines can be adjusted to the size of the nuts. In this way an optimal result is achieved.
A prior calibration of the nuts is necessary, otherwise smaller nuts will not be broken and larger nuts may be crushed. The hazelnuts can be sorted using a calibration sieve or a fully automated calibration machine according to their size. This ensures a very good cracking result.

Calibration sieve
Separate nuts according to three sizes.
The calibration sieve is used to sort nuts into 3 different sizes. The calibration sieve is placed over 3 fruit boxes. The openings of the sieve, i.e. the calibration size, becomes larger from left to right.
For calibration, place the walnuts on the left side and slide them from left to right over the calibration sieve. The calibration sieve is also available for hazelnuts. With the calibration sieve for hazelnuts, the calibration sizes are considerably smaller and this means they are adapted to hazelnuts.

Benefits
- very simple handling
- fast calibration of the nuts
- simple transport thanks to light weight
- other calibration sizes possible upon request

Calibrate from 100 kg to 1,000 kg nuts per hour.
The nut calibration machine has a calibration drum. This can sort the nuts in the same operation according to the same or 2 different sizes (optionally also up to 4 sizes). In addition, the sorting sieve can be changed easily and quickly.
Calibration sieves are available for every diameter. The working and total height are variably adjustable. The drive of the cylindrical calibration machine is via a worm gear or with an elastic coupling. Using an optional plastic sieve, chestnuts can also be gently calibrated.

Washing and calibration machine
The universal machine for cleaning, calibration, and dividing walnuts.
The washing and calibration machine cleans and sorts the nuts according to size. Thus, up to 95% of the raw shells are separated from the nuts. For the cleaning, a wash drum (oval design) is used. The roller / drum is then exchanged with a round hole sieve for calibrating the nuts.
You can choose between two calibration sizes. It is driven by a standard drill. Optional with nut feeder or electric motor with 230V.

WAL MAN hand cracker and accessories
Professional processing of smaller quantities of hazelnuts and walnuts
The WAL MAN and WAL MAN small are automatic, hand-operated nut crackers. Depending on the design, either up to 15 kg/h or up to 30 kg/h can be cracked. The nut cracker is very easy to use and is impressive due to its robust construction. Made in Germany. The cracking result is very clean with up to 40 % half cores for top quality walnuts and about 70 – 80 % whole cores for walnuts.
The WAL MAN is also optionally available with mechanical drive (electric motor) or shell remover with blower.

Feeder for P80 / P80S
Transport and calibrate nuts in the hazelnut cracking machine.
The feeder is an attachment for the P80 or P80S hazelnut cracking machine. The nuts are transported into the cracking machine via the feeder. In addition, the feeder allows only a pre-set size of nuts to fall into the cracking machine.
The larger nuts fall into a separate discharge point. The feeder can be used as pre-sorting for direct cracking as well as for just the calibration. To do this, simply unscrew the opening of the cracking machine completely so that the nuts fall through without cracking.
