Seed Sizing

The segmentation or sizing of the seeds is done by flat screen sizers which are provided with sieve frames with electric vibration motors. The vibration motors take care for an excellent movement of the sieve frame and this result in a very accurate seed size segmentation. One sieve frame can hold 2 sieves. This can be sieves with round or slotted perforation. By placing the flat screen sizers in line, seed lots can be calibrated in 3,5,7 or more fractions at once.

Seed sizing is part of our Seed processing program.

Agratechniek also provides installations for Seed drying, Seed breeding, Seed treatment and Seed climat control.

Flat Screen Sizer Unit for seed - Agratechniek from Agratechniek BV.

 

The segmentation of the seeds is done by flat screen sizers which are provided with sieve frames with electric vibration motors.

 

The dimensions of the sieving plate can be:

1000 x 400 mm.

1260 x 1000 mm.

1510 x 1000 mm.

Other sizes available. The screens are made with round and slotted holes for the optimal sizing of seed.

Seed Supply:

Seed can be supplied by hopper bins or with a box tipple unit. The seed supply unit for hopper bins can hold 4 hopper bins. The seed supply is done by a feeding belt. The speed of the dosing belt is adjustable. This result in a very smooth and uniform seed supply. The seed supply can also be done by a box tipple unit. The tipple unit can empty different kind of storage bins. The seeds will be collected in a funnel shape bin and from there dosed to the sizer by a dosing belt.

* Double hopper bin supply unit have two small dosing funnels.

** Box tipple supply unit have one larger dosing funnel.

Sieve frame:

The sieve frame stand on four air shock absorbers and two vibration motors take care for the movement of the sieve frame. This combination result in an excellent movement of the sieve frame and a very good and accurate calibration process. Other real benefit is that the flat screen sizer is very quiet and that the main frame does not vibrate and send no vibrations to the floor.
