Seeding Line

Technical Information:

  • The Sigma drum seeding line can reach a production up to 1800 trays/hour.

  • The de-nester is fed by an in-feed belt where stacks of trays can be placed.

  • The trays advance one next the other on the tray filler belt, ensuring the maximum filling uniformity in every cell, also in those along the edge of the tray.

  • The filling can be adjusted with one single handle and enables a variable filling with soft, medium or high density.

  • The brushing group perfectly cleans the trays from the excess soil, which is completely recycled without any wastage.

  • The driven dibbler ensures a centered position in the cell and a perfectly regular shape of the hole.

  • The engineering solutions of the seeding group produce a perfect singularisation with both small and big seeds. A second seeding drum can be added for multiseeding or chemical grains dispensing.

  • Changing the seeds or the trays is quick and easy thanks to the stored programs on the touch screen display and the no tools adjustments for changing trays, seed drums and dibble drums.

  • The drum coverer for vermiculite or other grains performs a great uniformity and enables to choose the working width and the quantity of product distributed, to reduce any wastage.

  • Each component of the machine is designed to improve the work of operators, thanks to fast adjustments, low noise, high quality and strong building to reduce maintenance.

  • Max tray dimensions 600x400mm.

  • Air usage up to 300L/min max

  • Water usage up to 25L/min max

  • Power 12Kw 400V 3 phase 50/60Hz
