MACHINE DESCRIPTION - ALFA65
The ALFA65 drum seeding line is a high performance modular line, capable of seeding up to 1200 containers per hour.
It is suitable for all types of trays: polystyrene, thermoformed and rigid injection molded plastic. Depending on the used type, a distributor is available that allows the automatic insertion of empty containers in the line.
The filler guarantees excellent coverage uniformity for all the cells, the ability to adjust the final density of the soil and has an additional hopper for the automatic recovery of excess peat.
The heart of the machine is in the ALFA seeder: the outgoing containers pass under a marker drum that allows the creation of a central and homogeneous imprint in which the seed will be placed. The second phase is that of sowing with the seeds that are positioned in a single, precise and homogeneous manner via a dedicated drilled drum.
The flexibility of the Urbinati machines and the incomparable suction power make it possible to sow all types of seeds, regardless of size.
Lastly, the covering and watering unit complete the seeding cycle, while the stacking unit, with the balance stacker, sorts the newly seeded containers in orderly stacks to make it easier to extract or palletise them.
Each component of the machine is designed and built according to the customer’s needs, to improve the work of the operators, to reduce maintenance and speed up seed change operations.
