Unlike ordinary grain, seed's core value is its "vitality" — germination rate. Ordinary grain drying reaches 60–80°C, efficient but thermally damages the embryo; seed drying must be strictly controlled at ≤40°C to ensure germination ≥95%. If a batch of seed is ruined by drying, the loss is not hundreds of tonnes of grain value but a whole season's seed stock. Storage is equally demanding — temperature swings and excess humidity accelerate seed aging and lower germination.
Recommended solution
Seed-specific dryer
Low-temperature, high-volume design with precise drying-temperature control, for maize seed. Drying curves can be preset and program-controlled for high consistency between batches.
Key indicator: Post-drying germination ≥95%.
Constant temp. & humidity seed silo
Equipped with a precision temperature/humidity monitoring system; in-silo temperature swing held within ±2°C, humidity ≤60%. Optional standalone dehumidification unit and HVAC system meet long-term seed storage needs across climate zones.
Seed processing is a niche high-margin field: we use data-driven quality control (incoming moisture + germination test, ≤40°C staged drying curve, ±2°C constant-temp storage) to ensure germination ≥95%, differentiating from ordinary grain drying through expertise.

Frequently Asked Questions
How is seed drying different from ordinary grain drying?
A seed's core value is its vitality - germination rate. Ordinary grain drying reaches 60-80C, efficient but thermally damages the embryo; seed drying must be strictly controlled at <=40C low-temperature high-volume to keep germination >=95%. Ruin one batch of seed and you lose a whole season's seed stock.
How do you guarantee germination >=95%?
Through data-driven quality control: incoming moisture + germination test, <=40C staged program-controlled drying curves, and +/-2C constant-temperature storage (humidity <=60%). Seed processing is a niche high-margin field where our expertise differentiates us from ordinary grain drying.
What temperature and humidity does a seed silo require?
Seed silos carry a precision temperature/humidity monitoring system holding in-silo swing within +/-2C and humidity <=60%, with optional standalone dehumidification and HVAC to meet long-term seed storage across climate zones.
