Dryers for seeds and planting material

This category covers seed and planting material: grass seeds, alfalfa, beet, vegetable-crop seeds, amaranth, mustard, pumpkin and sunflower seeds, as well as pelleted and coated seeds. They all share one common requirement - after drying, the seed must remain alive.

The main value of seed material is germination and seedling vigour. Unlike commercial grain, here one cannot chase speed: the germ is sensitive to overheating, and too high a temperature irreversibly lowers the germination of the whole batch.

The customer's task is to bring the seeds down to a safe storage moisture without damaging the germ or disrupting the protective coat of pelleted and coated seeds. For this, dryers with a low-temperature, mild regime are selected.

Alfalfa seeds

Alfalfa seeds

A small legume seed; delicate drying is needed to preserve germination.

Suitable dryers: Scolari cabinet C / A series, Herbas, Ravaro RR

Beet seeds

Beet seeds

A pelleted / calibrated seed; drying is often associated with seed coating.

Suitable dryers: Scolari cabinet C (incl. pelleted seeds), Herbas, Ravaro RR

Vegetable-crop seeds

Vegetable-crop seeds

A high-tech segment; preserving germination and batch uniformity is critical.

Pelleted / coated seeds

Pelleted / coated seeds

Drying after applying the coat (pelleting / coating) with control of a mild regime.

Suitable dryers: Scolari cabinet C, Herbas, Ravaro RR

Amaranth

Amaranth

A very small seed; a sealed flow path and careful airflow are needed.

Suitable dryers: Scolari cabinet C, Alvan Blanch DF, Herbas, Ravaro RR

Features of drying seeds and planting material

The key difference between seed material and commercial grain is the priority of preserving germination over drying speed. The germ dies when overheated, so seeds are dried at markedly lower heating temperatures and more slowly, releasing moisture gently without thermal shock.

Many seeds in this group are very small and light (grass, alfalfa, amaranth, beet seeds) and are easily carried off by the airflow - screens and an airflow regime suited to the fine fraction are needed. Pelleted and coated seeds require special care: it is important not to damage the protective coat carrying the treatment chemicals and not to overheat it.

Frequently asked questions

How does drying seed material differ from drying commercial grain?

For seeds the priority is preserving germination, not drying quickly. They are therefore dried at lower temperatures and more slowly: the germ is sensitive to overheating, and thermal shock irreversibly lowers the germination of the batch.

Why is low-temperature drying so important for seeds?

High temperature damages the germ and lowers germination and seedling vigour. A mild, low-temperature regime makes it possible to bring the seeds to the required moisture while preserving their sowing qualities.

Which dryer is suitable for seeds and planting material?

Low-temperature tower, batch and chamber dryers with a mild, even regime. For small seeds (grass, alfalfa, amaranth, beet) screens and airflow that prevent the light seeds from being carried off are needed.

Can pelleted and coated seeds be dried?

Yes, but with particular care: it is important not to overheat or damage the protective coat carrying the treatment chemicals. A delicate low-temperature regime is used for them.

What data is needed to select a dryer for seeds?

The seed type, initial and target moisture, fraction, batch volume and germination requirements. From these a low-temperature regime and a suitable dryer type are selected.
