Title: Methods and devices for preparing flower bulbs
Inventor: IWANEK GUENTER
IPC: A23N15/08
Filed: 1989-02-02
Abstract: The invention relates to devices and methods for preparing flower bulbs for sale. The harvested bulbs are fed in a random manner to a conveyor belt which conveys them through a preliminary station in order to free the bulbs mechanically from earth residues and for removing and separating out small bulbs. The large bulbs, which have root balls, are then fed singly to an upwardly directed airstream. In the said airstream, the bulbs are aligned in such a way that their root balls point upwards following the parachute principle. At the same time, the positions of the bulbs are stabilised, the bulbs then being transferred from the airstream into a clamping and conveying device. In the latter, the bulbs are separated from their root balls. Then the large bulbs which have been separated from their root balls and the small bulbs which do not yet have any root balls are collected in a collecting container.
