Production line and factory setup overview
A controlled mechanical saw-delinting line removing residual short lint from properly ginned cottonseed through seed receiving, moisture and foreign-material checks, metered feeding, one or more saw-delinter passes, air separation of linters and motes, seed cooling and protected storage. It produces saleable cotton linters and cleaner seed for oil processing or planting only after the relevant quality tests.
Recommended lowest-entry line configuration For a medium entry, trial one 1.0-1.5 t/h, approximately 47 kW saw delinter with metered seed feed, magnet, aspiration, linter condenser and separate seed discharge. Start with one cut; add a second cut only if linter buyers and oilseed tests justify lower residual lint without unacceptable kernel damage.
Production process and implementation sequence
- Cottonseed receiving and sampling
- Moisture, metal and foreign-matter check
- Metered seed feeding
- First saw-delinter pass
- Linter and mote air separation
- Linter condensation and baling
- Seed cooling and inspection
- Separate seed and linter storage
Products, capacity and market fit
- Cottonseed from local ginneries can yield an additional short-fibre product.
- Delinted seed can improve handling for oil-mill preparation when specifications are met.
- One machine offers a medium entry before a 100-500 t/day multi-cut complex.
- Separate linter and seed buyers are required before investment.
- Cotton linters - Buyer-agreed cut, cellulose quality, moisture, trash and contamination - Cellulose, paper or specialty industrial buyers
- Delinted cottonseed - Controlled residual lint, kernel damage, moisture and heating - Cottonseed oil processors or approved seed users
- Motes and rejects - Segregated and assessed before recovery - Approved recovery or disposal
Core production machinery and line specifications
| Machine / stage | Function / value | Production note |
|---|---|---|
