IMPROVES CROP YIELDS, QUALITY, TUBER SHAPE AND SKIN FINISH
Unistar offers many advantages as a result of its advanced design. Performance testing in the field has demonstrated 30%-50% output gains over existing machines, more in certain conditions. Unistar uses latest Standen Star Technology. A rigorous testing program on many conditions and soil types around the world has proven that Unistar has achieved its design goals; effective separation at high speed, and superb reliability over many thousands of hectares continuous operation.
 
ACTIFLOW STARS - NOT AVAILABLE FROM COMPETITORS
Unique to STANDEN, UNISTAR stars in patented ACTIFLOW formation and UNDERweb make a powerful combination. UNISTAR stars are larger in diameter (320mm) and considerably more aggressive than previous designs. Manufactured from an advanced hard wearing DUROPOL polymer, there are 10 rows of stars mounted on heavy-duty shafts in ACTIFLOW (patented) formation to spread material across the complete star bed.
 
EASY TO OPERATE, SIMPLE TO MAINTAIN
An ‘UNDERweb’ secondary separator is located beneath the rear six rows of stars, extending to feed clods/stones to the cross conveyor, thereby creating an additional drop and dramatically enhancing separation. So whilst stars effect primary separation, final grading is controlled by the UNDERweb. Thus it is no longer necessary to change star spacers for different requirements; previous star soil separators machines would be specified as 2-spacer machines for clod, or 1-spacer for stone. A simple web pitch change (from 36mm to 50mm can be specified) is all that’s needed.
