Key Technology Rotary Sizing and Grading Systems

Thursday, 16 November, 2023 | Supplied by: Key Technology Australia Pty Ltd

Key Technology has added new features to its Rotary Sizing and Grading Systems. The range, which includes the Precision Size Grader (PSG), Rotary Size Grader (RSG) and Sliver Sizer Remover (SSR), enables vegetable and fruit processors and packers to mechanically size and grade product while removing small pieces, debris and other targeted material. The systems are now available with optimised rollers, lubed-for-life bearings and drive covers.

New grooved rollers on the SSR facilitate the same throughput as traditional SSRs but with more precise product grading. PSGs retrofitted with the new grooved rollers achieve the same precision as traditional PSGs but with higher product separation efficiency. Suitable for wet potato strips and other cuts, with more applications in development, the grooved rollers are available as an option on new SSRs and as a field upgrade for installed SSRs and PSGs.

New lubed-for-life bearings, now standard on Key’s PSG, RSG and SSR and available for retrofitting, include a permanently lubricated stainless steel insert and newly developed blue polymer housing made from EC1935-compliant material.

An updated cover for the PSG, RSG and SSR features a singular latch mechanism instead of bolts, allowing easier access to the drive system, adjustment system and bearings for cleaning and maintenance. Additionally, perforations on the side of the cover provide better visibility while the cover is closed and enable an operator to spray through the perforations during routine cleanings.

Available in widths from 61 to 201 cm, the systems can achieve capacities from lower than 1.8 to more than 20.4 metric tons per hour.
