Hydraulic batch vs screw continuous: pick the process family before the model

Side-by-side

What changes for the buyer

• Production mode: hydraulic = batch barrels; screw = continuous stream.
• Cold press: hydraulic is strong (factory cold series 355–500, 370–630 ton); screw is limited by friction heat.
• Oil story: hydraulic suits roasted aroma oil and premium cold oil; screw suits bulk cooking oil.
• Capacity language: hydraulic uses barrels/shift and cycle time; screw uses kg/h continuous.
• Maintenance: hydraulic focuses on seals, gauges, and cloth/partitions; screw on worn screws and barrels.

Choose hydraulic

When a hydraulic sesame line is the commercial fit

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). Small commercial mills often sit around 0.3–5 t/day with batch hydraulic; large continuous plants push screw or solvent.

Before you inquire

Send this so we do not quote the wrong family

• Seed and form (whole, kernel, roasted, dried).
• Target product: bulk crude, filtered retail, cold-press claim, or roasted aroma oil.
• kg per shift and number of shifts — not only annual tons.
• Whether cake is sold for feed, food flour, or discarded.
• Power supply (380V/50Hz/3ph typical) and workshop photos.

What to confirm before scoping Hydraulic vs Screw Oil Press for sesame: Which Fits Your Mill?

Hydraulic vs Screw Oil Press for sesame: Which Fits Your Mill? 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 Sesame Oil Press modules stay. Factory sesame hot: ~30 kg/batch with 6 partitions on 325; cold uses 355–500. Do not use peanut 100 kg barrel loads.

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

When discussing Hydraulic vs Screw Oil Press for sesame: Which Fits Your Mill?, pin models to published factory specs — not tonnage alone.

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.
• Factory sesame hot: ~30 kg/batch with 6 partitions on 325; cold uses 355–500. Do not use peanut 100 kg barrel loads.
