SPIRAL SERIES / SORTING TECHNOLOGY

SPIRAL Series

Aspirators & Gravity Separators machines

The PETKUS Selecta Spiral separator is very suitable for separation of seeds on shape: round from angular, flat or oval seeds. It can be used to separate soil and weeds from brassica seeds, weeds from spinach etc.
With spirals the quality and precision of the equipment are determent for the separation results. Selecta has an outstanding record of high quality products.

MAIN FEATURES

ADJUSTABLE FEEDER

The Spiral 4.5 and 6.0 are equipped with a VIDOS electrical step less adjustable feeder, self-cleaning and easy to inspect. The feeder ensures a constant flow without clogging which makes continues operation of 24 hours a day possible.

ADJUSTMENT OF THE SEPARATION

By using a set of brushes insertend at inner spirals at the height where the "bad“ seeds start to swing out. The "bad“ seeds are forced back into the inner spiral and will remain there. Because the set of brushes can be inserted everywhere at the inner spirals. The separation can be precisely adjusted all adding up to superb results.

CUSTOMIZED OPTIONS

It is possible to deliver the spiral separators with 2 or 3 outlets, depending on the seeds you have to separate.
The standard model has 2 outlets at 180 angle. By using the insert set of brushes the extra outlet (third outlet) in the outer spiral for an extra separation of the "swug-out seeds“ is not required any more for the majority of seeds.

HOW DOES IT WORK?

The short Spiral separator can be used to remove soil and weeds from round seeds that remain in inner spirals.
The long Spiral separator is specially designed to separate soil and weeds from angular and flat seeds. In this machine the weeds and other debris are in the outer spiral, whilst seeds remain in in the inner spirals.

Spirals provide fully automatic operation without any moving parts. The Spiral separator can be used as stand-alone or in a cabinet to increase capacity. The seeds are carried into the feeding inlet on top. The inlet is provided with a distribution unit to guarantee an even spreading of the seeds in the machine. The round and smooth seeds move faster and therefore reach the outer spirals. The angular seeds move slower and remain in the inner spirals.
