Clear sunflower oil is designed after pressing

Wax behavior

Why sunflower oil clouds in cool storage

• Natural wax dissolves in warm oil and crystallizes as temperature drops.
• Whole-seed pressing and high residual hull usually increase wax transfer.
• Dewaxing uses controlled cooling, hold time, and filtration; it should be sized by daily oil output.

Finish options

Match filtration depth to the container

Filter depth

Filtration should be priced by final oil destination

• Crude bulk oil may need only settling and coarse filtration if the buyer's refinery accepts wax and color.
• Dewaxed bottled oil needs cooling, hold time, wax filtration, polishing, and clean post-filter storage.
• Refined retail oil connects degumming, neutralization, bleaching, deodorization, dewaxing, and filling hygiene.

Filter proof

Filter planning needs oil samples from different temperatures and stages

• Collect oil at press discharge, after settling, after coarse filtration, after chilling, and after final polishing if those stages exist.
• Those samples tell whether the problem is suspended solids, moisture, wax crystals, dark color, or a final bottle hygiene issue.
• The quote can then separate coarse filter, dewaxing filter, polishing filter, clean tank, and filling-room responsibility.

Next decision

Split filtration into coarse, dewaxing, polishing, and filling protection

• A single filter name is not enough for sunflower oil. The buyer should say which stage removes press fines, which stage removes wax, which stage protects clear storage, and which stage protects filling.

Project boundary

What to confirm before scoping Sunflower Oil Wax, Filtration, and Refining Planning

Sunflower Oil Wax, Filtration, and Refining Planning 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 Sunflower 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

Post-press 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.
