Expert support for every Product Group:
Seed Extraction Solutions
We design extraction solutions based on crop type, lot size and process flow. For fruits like tomatoes, cucumbers and peppers, we offer equipment scaled for small batches up to large production volumes. Critical factors include water availability, drainage and fermentation needs.
Looking to optimise your extraction process? Our specialists will advise you on the ideal setup.
Seed Threshing Installations
Threshing dry crops—such as umbellifers, ears or pods—requires the right balance of technique and capacity. We help define the full setup: from drying and feeding logistics to waste handling and dust control, ensuring a seamless and clean workflow.

Seed Drying Installations
Drying is critical to maintaining seed viability. Based on your process data, we design energy-efficient drying lines with the right airflow, dehumidification capacity, and automation level to suit your seed types and volumes.
Ensure top-quality seed drying. Partner with SPH for a custom-engineered drying solution.
Seed Cleaning Systems
Seed cleaning demands precision. Our designs are based on input data such as seed type, purity levels, capacity and available space. We integrate Clean In Place™ systems to reduce downtime and improve hygiene between batches.
Achieve uncompromising seed quality with a cleaning solution engineered by SPH.
Seed Pelleting Installations
Pelleting improves seed handling and planting accuracy by creating uniform, round pellets. We design integrated pelleting lines that manage powders, liquids, dust control, and operator safety — all tailored to your capacity and process needs.
Ensure precise pelleting with a custom-engineered solution by SPH.
Seed Treating Systems
Seed treating protects seeds with precise application of chemical or biological agents. Our rotary coating and dosing systems ensure accurate coverage, with careful integration of liquid handling, discharge, drying, and safety measures — all tailored to your process.
Protect your seeds with a high-performance treating solution by SPH.
Seed Priming Installations
Seed priming boosts germination and breaks dormancy through controlled hydration techniques. We design tailored systems with precise control of oxygen, temperature, and timing — all aligned with your process, capacity, and safety requirements.

SPH Seed Moisture Content Conversion Table
This table clearly shows the relationship between absolute seed moisture content (MC) and relative humidity (RH) for various seed crops, as well as equilibrium moisture content.
In Seed Processing Holland’s drying systems, air flows are monitored with RH sensors both below the seed bed and above the seed bed during the drying process, ensuring precision at every drying stage.
The table allows conversion from relative humidity to absolute moisture content. A commonly used target for final water activity after drying is 30% RH. It is important to note that the RH-MC relationship varies for different seed crops. By maintaining a well-controlled, dehumidified air drying process, you can ensure the quality and shelf life of your valuable seeds.
