Holaras - Model AS - Oniontopper
When using the -holaras- topping machines, the haulm is not pulled off, but cut of by fast rotating blades. This avoids damage because the blades do not touch the onions. The number of directed vibrations transmitted by specially designed vibrator-motors on the vibration-sieves is such that the onions move in a floating motion over the vibrationnsieves. The haulm (tops) is drawn through the openings into the sieves by a heavy airstream, downward, and then cut by the blades.
