菜籽油 · Rapeseed / Canola Oil Press line scope and commercial fit
Start here when the product direction, downstream handling, and workshop limits need to be clear before equipment is selected.
Commercially, rapeseed buyers split into traditional flavor-oil regional brands and canola RBD commodity producers, with very different downstream requirements despite using similar pressing equipment.
Traditional Chinese-style rapeseed flavor oil
Regional brands selling hot-pressed traditional rapeseed oil with strong nutty aroma for Sichuan/Hunan/Jiangxi cuisine. Light filtration only, no full refining. Dark glass bottles preserve flavor.
Canola RBD cooking oil mills
Mid-to-large mills processing canola seed into refined cooking oil for domestic retail. 300/325 hot press + full RBD refining + PET bottling. Cake sold as canola meal for pig and poultry feed.
Rapeseed-growing-region cooperatives
Cooperatives in rapeseed belts (Yangtze valley, prairie Canada, EU) adding pressing + refining + bottling value instead of selling raw seed. The combined oil + cake revenue supports small-to-medium plant economics.

Avoid rework
Checks that keep the line from being underspecified
- Traditional rapeseed and canola are different products. Verify the variety at intake — mixing them on one line without changeover compromises both flavor oil and refined oil quality.
- Pre-cooking at 100–110 °C is essential for hot-press yield and characteristic flavor. Cooker capacity must match press throughput, not be sized as an afterthought.
- Crude rapeseed oil always needs refining for retail. Plan the RBD train (degum + neutralize + bleach + deodorize) alongside the press, not as a future addition.
- Canola cake (low glucosinolate) is feed-grade up to 15% in pig/poultry diets. Traditional rapeseed cake is best for ruminants or fertilizer due to higher glucosinolates.
- Hot-press cycle is 30-40 min/barrel on 300/325 series. Plan daily output from this cycle plus loading/unloading time, not from a brochure throughput number.
Line inputs
Information that changes the equipment boundary
- Variety: traditional high-erucic rapeseed or low-erucic canola.
- Daily seed input and target shift output, in tons of seed processed.
- Hot-press or cold-press route, and whether the line includes pre-cooking.
- Whether full RBD refining is in scope or the project ends at crude oil.
- Cake market plan: canola feed (with glucosinolate spec) or traditional cake for ruminants/fertilizer.
- Bottling format: PET retail, glass for flavor oil, drums for foodservice.
