Sunflower byproducts include both cake and hulls

Data

Send cake and hull routes before final layout

• Cake outlet: feed, storage, sale, or further processing.
• Hull outlet: fuel, bedding, feed fiber, sale, or disposal.
• Dust control, bagging, truck access, and storage volume.

Sales outlets

Cake and hulls should be sold or removed through different routes

• Cake value depends on protein, residual oil, hull carryover, cake size, cooling, and whether local feed buyers accept it.
• Separated hulls may be fuel, bedding, fiber filler, compost, or low-value residue; each route changes storage volume and dust control.
• If cake is bagged for feed sale, bag weight, cooling time, sewing, pallet space, and truck pickup should be planned with the press bay.

Traffic split

Keep dusty hull traffic away from clear-oil handling

• Hull dust should not cross dewaxing filters, clean tanks, bottle-ready hoses, or filling-room doors.
• Manual carts can work for small mills, but growing plants should reserve conveyors, bins, or bagging points early.

Buyer channel

Cake handling should be planned from the local feed or biomass buyer backward

• Ask whether the cake buyer wants whole cake, broken cake, meal, bagged feed material, bulk truck loading, or moisture-controlled storage.
• Ask whether separated hulls have value as boiler fuel, bedding, fiber filler, compost, or must be removed as low-value residue.
• These buyer channels decide whether the quote needs only carts, or also conveyors, cooling, crushers, bagging scales, silos, and dust collection.

Next decision

Decide whether cake is a sale product, a feed ingredient, or a residue

• Sale product needs cooling, shape control, bagging, labels, and buyer pickup. Feed ingredient needs moisture and hull language. Residue only needs safe removal, but still needs dust and truck access.

Project boundary

What to confirm before scoping Sunflower Cake, Meal, and Hull Handling

Sunflower Cake, Meal, and Hull Handling 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

Downstream 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.
