Processing Technology
Our flaxseed hulls are produced using advanced mechanical separation and dry peeling processes. The main equipment includes:
Vibrating screen seed classifiers
Precision dehullers
Air separation systems
High-efficiency oil separation dryers
Low-temperature milling units (optional for powder form)
This ensures minimal contamination, optimized oil retention, and preservation of mucilage components for functional food or feed applications.

FAQs
Q1: What is flaxseed hull (linseed hull)?
A1: Flaxseed hull — also called linseed hull or shell — is the outer layer separated from whole flaxseed through mechanical dehulling. It’s a fiber‑rich fraction with retained mucilage (gum) components and a lower oil content compared to whole seeds.
Q2: How are flaxseed hulls processed?
A2: Flaxseed hulls are produced using advanced mechanical separation and dry peeling systems, including precision dehullers, screening, and optional low‑temperature milling to ensure minimal contamination and optimized functional properties.
Q3: What are the functional characteristics of flaxseed hulls?
A3: Flaxseed hulls are rich in dietary fiber and mucilage (flax gum), which provide water retention, texture, and functional benefits in formulations. They also contain residual oil and can contribute to antioxidant activity and gut health applications.
Q4: What industries and applications use flaxseed hulls?
A4: They are widely used in animal nutrition (fiber additive, digestive support), functional foods and dietary supplements, pet food (fiber‑rich formulas), cosmetics (natural emulsifier & hydration additive), and bio‑industrial uses such as biodegradable materials and fermentation enhancers.
Q5: What packaging options are available for flaxseed hulls?
A5: Bulk flaxseed hulls can be supplied in 20 kg kraft paper bags, 25 kg woven bags with liners, or 1000 kg jumbo (FIBC) bags, with OEM private labeling available.
Q6: How should flaxseed hulls be stored and what is their shelf life?
A6: Store in cool, dry, ventilated areas, avoiding direct sunlight and humidity. Under sealed storage, flaxseed hulls typically maintain quality for about 12 months.
