All-pneumatic laboratory seed cleaner successful
A laboratory seed cleaner and separator (a two-stage aspirator) has been developed at the Forestry Sciences Laboratory, Corvallis, Oreg., combining characteristics of the South Dakota blower and the Silen seed separator apparatus. The two-stage aspirator is constructed of Plexiglas tubing and uses a commercial vacuum cleaner to separate seed and debris. Coniferous seed lots of many species have been processed to 98- to 99- percent filled seed using this device.
