Clear sunflower oil is a wax-control project

Clarity data

Define clarity at storage temperature, where haze appears

• State whether the oil leaves in clear bottles, drums, or refining feed.
• Confirm expected storage and sales temperature.
• Decide if dewaxing, winterization, or only filtration belongs to the scope.

Cold test

Light color and clear storage are two separate promises

• Kernel cold pressing can make oil paler, but wax can still crystallize when the bottle sits in cool storage.
• A clear-bottle promise should name cooling temperature, holding time, wax filtration, final polishing, and sample approval.
• If the buyer accepts haze because oil goes to refining, do not overprice a retail dewaxing package.

Equipment scope

Clarity scope sits after pressing and before filling

• The page should connect crude settling, cooling, wax crystal formation, filter area, clean tanks, and bottle transfer.
• This makes the search intent different from a generic cold-press page and captures dewaxing keywords directly.

Quality proof

The clarity page should separate oil color, sediment, and wax haze

• Ask for warm oil photos, chilled oil photos, settled tank bottom photos, and whether haze disappears after warming.
• Sediment points to cleaning, pressing, settling, or coarse filtration; wax haze points to dewaxing, cooling, hold time, and fine filtration.
• This lets the page capture searches for sunflower oil dewaxing instead of being just another cold-pressed oil description.

Next decision

Decide whether the haze is acceptable, removable, or a reason to refine

• If haze is acceptable for crude sale, keep the offer lean. If haze must disappear in retail bottles, include dewaxing and cold approval. If color, odor, and haze all matter, discuss refining rather than filtration alone.

Final check

Record one chilled sample result before freezing the quote

• This single result decides whether clarity is a filter issue, a wax issue, or a refining issue.

Project boundary

What to confirm before scoping Light-Color Sunflower Oil Clarity and Dewaxing

Light-Color Sunflower Oil Clarity and Dewaxing 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

Quality 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.
