Feed-linked mill
Meal cooling, protein, bagging, and pickup rhythm are as important as crude oil.
RFQ intent
The same feed tonnage can produce very different equipment scopes if dehulling, degumming, meal cooling, refining, or a high-protein meal target is added.
Project fork
Meal cooling, protein, bagging, and pickup rhythm are as important as crude oil.
Storage, settling, phospholipid handling, and refinery acceptance decide the post-press scope.
Non-GMO identity, lot records, lower-temperature route, and clean transfer change the line.
Pricing inputs
Avoid re-quoting
A press-only price is not comparable with a line that includes dehulling, hull separation, cracking, and conveying.
Soybean crude oil may need degumming and refining; if the final product is bottled oil, include that direction from the first inquiry.
Annual tonnage, daily feed, shift output, and press-cycle assumptions can describe very different equipment scopes.
Project boundary
Soybean Project Data Before Pricing should not be quoted from an equipment name alone. Check feed lots, target oil, post-press handling, and packing rhythm in one scope before deciding which Soybean Oil Press modules stay. Listed on the factory hot-press page — discuss 300/325 first.
When feed condition, moisture, impurities, batch weight, and product position are unclear, press tonnage and filter area become guesswork. Factory systems share 60 MPa and 2.2 kW motors; hot pure press is 30–40 min/barrel and cold pure press is ~2 h/barrel — cycle time matters more than brochure tonnage.
Factory model check
Pin models to published factory specs before tonnage talk.
Hot 300/325: 300–325 ton, 60 MPa system, standard barrel Ø390×800 mm / max 100 kg, pure press 30–40 min/barrel, ~1.5 h for 2 barrels with loading, 2.2 kW motor. Cold 355/400/426/480/500: 370–630 ton, integrated frame, same 100 kg standard barrel, pure press ~2 h/barrel, ~4.5 h for 2 barrels with loading; optional Ø300 high-pressure barrel max 60 kg. Residual oil target ~≤5% (peanut hot often 6–8% measured).
Equipment check
Once the route is clear, write the interfaces: how preparation feeds the press, how oil leaves the press, how filtration connects to tanks, and how packing receives finished oil.
Record feed form, daily volume, moisture, and sorting needs so pretreatment is not left to operators.
Crude soy oil holds 1.8–2.5% phospholipids — hydration degumming and lecithin drying are often phase-one. Meal protein 44–46% or 48–50% dehulled needs an offtake plan.
Prepare space, power (often 380V/50Hz/3ph), labor, target package, local rules, and acceptance method before quotation.
For a serious project, do not plan it that way. Cleaning, removing metal and stones, cracking or splitting, and controlled conditioning make the press cycle predictable and protect crude-oil quality.
Hot pressing is usually the practical route when yield, stable flow, and feed-linked meal value matter. Cold-positioned soybean oil is a specialty route and needs lower-temperature conditioning, smaller batches, and honest expectations on output.
Soybean crude oil normally carries phospholipids and fine solids that affect storage, filtration, degumming, and refining. The tank and filter plan should be discussed with the press scope, not after equipment arrives.
Meal is not waste. Many projects sell it to feed buyers, return it to a livestock operation, or specify protein and residual-oil targets before the press route is finalized.
