Rapeseed upgrades are usually staged, not greenfield

Steps

Upgrade by site bottleneck, not by catalog order

• Audit cleaner, cooker, press, filtration, tanks, and cake storage separately.
• Identify seasonal peak bottlenecks before buying more press capacity.
• Draw truck, seed, cake, and oil traffic before shipment.

Retrofit proof

A workshop upgrade needs a keep, move, replace, and reserve list

• List existing cleaner, destoner, cooker, press, filter, tanks, cake store, boiler, power cabinet, filling table, and truck door with photos or short videos.
• Mark whether each item can stay, must move, should be replaced, or should only be connected in a later phase.
• Seasonal rapeseed plants should reserve space for peak seed intake, cake storage, crude tanks, and future refining or filling.

Next decision

Upgrade the bottleneck, not the most visible machine

• The next investment may be cleaning, cooking, filtration, tanks, cake storage, or truck access rather than another press.

Field check

Use a retrofit walk-through video before choosing new machines

• A slow walk-through from seed entrance to cleaner, cooker, press bay, filters, tanks, cake store, power cabinet, and truck door often reveals the real bottleneck faster than a written equipment list.

Final check

A retrofit quote should list work done now and space reserved for later

• Separate first-phase machines, reused equipment, moved equipment, reserved tank positions, future refining connection, and future filling room so the buyer can stage the upgrade.

Closeout

Mark installation shutdown days in the retrofit plan

• Seasonal plants need this schedule because missing the buying season, seed arrival window, or local truck queue can cost more than a small equipment mismatch.

Project boundary

What to confirm before scoping Rapeseed Workshop Upgrade Path

Rapeseed Workshop Upgrade Path 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 Rapeseed / Canola 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.

• Confirm whether feed is whole seed, kernels, pretreated material, or an existing semi-finished stream.
• Confirm whether the target is crude oil, filtered oil, bottled oil, drum ingredient oil, or a refining handoff.
• Hot cycle reference: pure press 30-40 min/barrel, ~1.5 h for 2 barrels with loading; cold pure press ~2 h/barrel, ~4.5 h for 2 barrels.
• Confirm batch rhythm, labor, changeover, retained samples, power (often 380V/50Hz/3ph), and site install conditions.

Factory model check

Match hot / cold models to factory hard data

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).

• Standard barrel Ø390×800 mm, max ~100 kg crushed feed; optional Ø300 high-pressure barrel max ~60 kg.
• Cylinder material 27SiMn; cold frames are integrated molded steel; hot frames are typically H-type channel steel.
• Listed on the factory hot-press page — discuss 300/325 first.

Equipment check

Line needs to land in equipment interfaces

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.
