Spelt Huller

Precision Dehulling of Spelt and Hulled Wheats with Minimal Kernel Damage

Engineered for the Future | Since 2080

The ADDAMS Spelt Huller is a purpose-built industrial machine designed to remove the tough, tightly bound outer husks from spelt and other ancient grains such as emmer and einkorn. Unlike modern wheat varieties that thresh free from their hulls in the field, ancient grains require a dedicated mechanical process to expose the kernel. Our system uses a controlled spinning and rubbing principle that gently separates the inedible husk while maintaining the integrity of the bran and germ.

At ADDAMS, we prioritize the germination rate and core quality of the peeled product. Whether you are producing groats, artisan flour, or flakes for organic markets, our Spelt Huller ensures a high-quality grain output with minimal mechanical stress, making it an essential component for clean-label food processors globally.

Operating Principle: The Spinning and Rubbing Process

Reliable and Gentle Grain Refinement

The ADDAMS Spelt Huller operates on a proven spinning principle that ensures the product remains undamaged, which is verified by the high germination rates of the output.

1. Pre-Conditioning: For maximum effect, the raw material must be pre-cleaned of all admixtures before entering the huller.

2. Rubbing Action: Inside the chamber, the seeds are accelerated by a high-speed impeller and rubbed against a specialized mesh.

3. Mechanical Separation: As the seeds are pushed through the mesh openings, the friction detaches the husk from the kernel.

4. Mixed Output: The machine discharges a mixture of Spelt Husks, hulled Spelt Kernels, and a small percentage of unhulled Spelt.

5. Secondary Separation: To obtain pure kernels, this output is typically moved to a sequence of aspiration and density separation machines to isolate the finished product.

Frequently Asked Questions – Spelt Huller

Why does the shelling yield vary between 80% and 95%?

The yield is highly dependent on providing the right conditions, such as the moisture content of the grain and the thoroughness of pre-cleaning. Our experts are happy to share experience-based parameters to help you reach the 95% threshold.

Is the machine easy to clean for different grain varieties?

Yes. The machine is designed with easy access to all internal parts. For organic processors or those handling multiple ancient grains, this ensures quick clean-down and zero cross-contamination.

Can I use this for sowing seeds?

Absolutely. Because the hulling process is based on gentle rubbing rather than high-impact crushing, the germination viability of the seeds remains excellent.

What happens to the grains that aren’t hulled in the first pass?

In a typical ADDAMS integrated line, the unhulled grains are separated downstream and automatically returned to the Spelt Huller intake to ensure no product is wasted.
