The PETKUS Selecta Zig-Zag aspirator is a machine designed to separate seeds based on specific weight in a vertical ZZ shaped column for both seed production and laboratory purposes. It was specially developed for gravity separation of small batches with a high level of accuracy which is equivalent to that of a gravity table and even higher when sorting flat and/or long seeds.

It can be used for all kinds of vegetable and flower seeds. There are no limitations. We are building machines for fine seeds, vegetables, flowers and small volumes of other seeds (grasses, rice, etc).

Characteristics

•    High accuracy of separation, precise separation adjustments, easy reproduction of results
•    Self-cleaning, easy control through a glass window
•    Very easy to operate
•    Minimal loss of valuable seeds as all remain in transparent boxes / seed bins
•    Also suitable for very small batches (no minimum volume required)
•    Unlimited continuous adjustment of air fan
•    Regular flow feeding by VIDOS vibrating feeder
•    Dust-bag filter on air output for clean operation, does not need extra aspiration

HOW DOES IT WORK?

The electrically adjustable vibrating feeding hopper (1) ensures an even inlet of seeds in the adjustable airflow channel (3).

The seeds move into the Z-shaped air-channel and are met with an upward airstream whereby the heavy seeds fall down and are collected in a collecting-bin (4).

The light seeds are carried off by the upward airstream and are collected in the collecting-bin (6) underneath the air channel.

The air and the fine dust are blown out through the ventilator (7). The dust behind the ventilator is collected in a dust-bag with filter.

The VIDOS vibrating feeder is located in a vacuum-tight chamber (2) to prevent the airstream in the air channel from being disturbed. The air channel is very smooth and makes the machine self-clean for most seeds.

The front is covered with a glass-door (scratch-free and anti-static) which makes it possible to follow the process step by step. The air flow is continuously adjustable by a digital converter. The fan is very stable and operates silently. The vibrating feedinghopper is also continuously adjustable. The machine is built on a stable stand. All functions on the panel are next to the air channel and easy to handle.
