GreenBroz Precision Sorter: Size-Grade a Harvest Fast
The Precision Sorter grades flower by size so each lot can be trimmed, packed or priced on its own. Buds go into a stainless steel in-feed hopper and ride a conveyor onto a moving band. Stainless sectional dividers set the size breaks, and each size drops into its own container. Sorting sizes are adjustable to your own grades, so the same machine can split a harvest two ways or several. On its own the sorter handles 1.5+ lbs a minute, with a maximum of about 90 lbs an hour. Fed by a GreenBroz Rise Conveyor, throughput climbs past 5 lbs a minute. GreenBroz suggests it for cultivations of around 300 lbs. Band speed and conveyor speed are set separately on an HMI digital interface. The band runs up to 60 RPM and the conveyor up to 30 RPM. The frame is 316 lab-grade stainless steel with polyurethane and HDPE contact parts, chosen to keep flower clear of contaminants. A quiet, washdown-ready motor drives the line, and the unit draws 6 A at 120V. An adjustable front shelf and industrial locking casters let you park it where the line needs it. The sorter can also sit at the end of a GreenBroz trimmer so trimmed flower is graded as it comes off. It is made in the USA and carries a three-year manufacturer warranty.
Setting Up a Bud Sorting Machine in a Harvest Line
Roll the sorter into place and lock the casters before the first run. Plug it into a standard household outlet on its own circuit. Set the dividers to the size grades you sell, then start with a slow band speed. Feed a handful of buds and watch where each size lands before loading the hopper fully. Raise the band speed in small steps until the grades stay clean at the throughput you need. Keep the conveyor speed matched to the band so flower does not pile up at the transfer. Place a bin or tray under every drop point before starting a batch. Sorting before trimming lets similar-sized buds go through the trimmer together for a more uniform finish. Sorting after trimming gives consistent bag appeal across each grade. Less handling by staff keeps trichomes on the flower and shortens the time product spends out of storage. At the end of a shift, wash down the band and dividers. Let every part dry fully before the next harvest goes through.
