Pulses

Pulses such as soy beans, peas, field beans, vetches or lupines are anything but tough. Mechanical impacts on a pea or bean can easily hit the embryo, which lies directly under the seed coat and fills nearly the entire seed. The embryo’s positioning bares great impact on seed processing: the more exposed the embryo is, the more precise the technology must be. Inadequate technology can result in reduced germination capacity in the field and high grain loss of between 15 to 45 % during processing.

On spirals and poorly adjusted/functioning gravity tables, 20-50% of good quality seed is often rejected. Studies have proven that screens, spirals, and calibrators reduce germination capacity due to their exertion of mechanical stress. It’s a generally-accepted rule of thumb that each spiral sorting costs one percent of the germination capacity. Only gravity tables increase the quality parameters.

PETKUS Technologies offer solutions that set a high standard for gravity tables, provide a bypass function for spirals, and use optical sorting with colour and shape-recognition technology. With their unique scraper chains, PETKUS Cleaners have the most effective screen cleaning to date when it comes to soybean seeds, which have hulls that would otherwise clog all screens. The PETKUS Gravity Separator “G” Series ensures reliable sorting with minimal grain loss through its unrivalled homogenous airflow, storage of up to 500 different settings, and specialized decks for reduction of the inferior middle faction. The more round a grain is, the greater the need for sorting technology that not only recognizes colour, but shape. Only through such high technology is it possible to remove unwelcome product, e.g. such as small, black hilum soybeans. The release of the PETKUS OS 900 onto the market set the industry standard, as the OptoSelector uses both colour sorting and shape-recognition to achieve the highest level of precision.
