Open pageOil Seeds Pre-treatment Equipment
Pre-treatment is not one fixed machine package. The correct scope depends on the raw material, incoming impurity level, moisture, required particle size, hot- or cold-press route, press loading rhythm, and the finished-oil specification.
Select the Route Before the Equipment
- Small dry seeds: screen dust, oversize material, stones and metal before pressing. Start with the sesame screening machine when the material is sesame, rapeseed, flaxseed, perilla or another small seed.
- Hard kernels and nuts: confirm shell removal, grading and the particle size required by the selected press. A sample test should define whether the 11 kW pulverizer or another crusher is suitable.
- 300/325 hot-press projects: cleaning and crushing are followed by controlled steaming, conditioning or roasting. Compare the 27 kW electric steamer, wood-fired steamer and automatic drum roaster against the actual batch size and heat source.
- 355-500 cold-press projects: clean the material, use low-temperature drying only when required, then crush and load it directly into the hydraulic pressing barrel. Do not add roasting or high-temperature steaming to a cold-process quotation unless the buyer requests a different route.
- Fresh fruit, palm fruit, avocado and rice bran: these materials need a project-specific process review and must not be treated as ordinary dry oilseeds.
Typical Pre-treatment Modules
| Module | Purchase decision |
|---|---|
| Screening, aspiration and stone removal | Confirm feed cleanliness, screen opening, dust outlet and metal-removal requirement |
| Dehulling and separation | Confirm whether hull removal is required and how kernels, hulls and fines are collected |
| Crushing, flaking or grinding | Confirm target particle range, temperature rise, throughput and cleaning between materials |
| Steaming, conditioning or roasting | Confirm hot-process recipe, heat source, batch size, temperature measurement and discharge method |
| Conveying and buffering | Match the real capacity of each module to the press cycle, not only the nameplate throughput |
The feeding, crushing and frying integrated machine and pre-press machine are optional process modules, not universal requirements.
Information Required for a Factory Quote
- Raw-material name, photos or sample, impurity level, moisture and whether shells are present.
- Planned hot-press or cold-press route and the required finished-oil stage.
- Target batch, shift or daily production and expected material-change frequency.
- Selected press model, available floor space, voltage, heat source, dust extraction and local utility limits.
- Required scope: individual machine, connected line, controls, installation support, spare parts and documentation.
Acceptance Basis
Use the buyer's representative material to record feed condition, cleaned loss, particle-size setting, temperature where applicable, actual throughput, transfer stability, cleaning access and safety interlocks. Oil yield and oil quality remain results of the complete material and process route; they are not guaranteed by purchasing a pre-treatment machine alone.
