Comprehensive Guide to Constructing Large-Scale Palm Oil Plants (Targeting the African Market: Primarily FFB Milling Plants with Provisions for Future Refining Expansion)
Palm Fresh Fruit Bunch (FFB) Milling Plant: Uses FFB as raw material; produces Crude Palm Oil (CPO) and Palm Kernels (PK); must be located near plantations.
Palm Oil Refining/Fractionation Plant: Sources CPO as raw material; produces refined palm oil, palm kernel oil, and olein/stearin fractions; suitable for port locations.
Industry standard for "large-scale" plants: 30 t/h to 60 t/h FFB processing lines (daily processing capacity of 720–1,440 tons).
Critical Site Selection Rules (Determining Project Viability)
Raw Material Radius (Strict Limit)
FFB must be processed within 24 hours of harvesting; delays exceeding 48 hours lead to a sharp rise in Free Fatty Acids (FFA) and reduced oil extraction rates.
Optimal scenario: Stable supply of sufficient FFB within a 30–50 km radius of the plant.
Long-distance transport of fresh fruit to the plant is strictly discouraged.
Water Supply
Water consumption is 1–2.5 tons per ton of FFB; a 60 t/h plant requires ≥2,000 m³ of water daily; prioritize locations near rivers or areas with abundant groundwater.
Transportation
Direct access via main roads to accommodate continuous heavy truck traffic; include loading platforms for outbound transport in the crude oil storage tank area.
Energy Strategy
Standard feature for large plants: Biomass boilers utilizing Empty Fruit Bunches (EFB), fibers, and shells as fuel to generate steam; coupled with steam turbine generators for self-generated electricity, eliminating reliance on unstable local power grids.
Land Requirement Reference
30 t/h complete milling plant: 25–40 *mu* (approx. 1.7–2.7 hectares);
60 t/h milling plant + crude oil tank farm + wastewater treatment: 50–80 *mu* (approx. 3.3–5.3 hectares);
Reserve additional land if future refining and fractionation capabilities are planned. Complete Process Flow (Large-scale Continuous Pressing Line)
Fresh Fruit Reception → Sterilization → Threshing → Digestion (Cooking & Mashing) → Twin-Screw Pressing → Crude Oil Clarification & Purification → CPO Storage Tank
Press Cake → Fiber/Kernel Separation → Kernel Drying → Palm Kernel Temporary Storage (for external sale or dedicated kernel oil workshop)
Sterilization (Critical Stage)
Horizontal batch sterilizer; 0.3 MPa saturated steam; 90-minute cycle; inactivates lipases, controls FFA levels, and prevents crude oil rancidity.
Threshing
Rotary thresher; separates fruitlets from Empty Fruit Bunches (EFB); EFB can be returned to the field as fertilizer or used as boiler fuel.
Digester
Continuous heating and agitation; ruptures fruit pulp cells to maximize oil extraction yield.
Twin-Screw Press
Industry-leading performance: Using high-quality Tenera fresh fruit, the Crude Palm Oil (CPO) extraction rate is 21%–24%, with residual oil in the cake controlled at ≤1.2%.
Clarification Section
Heating, water dilution, sedimentation, and sludge removal via disc centrifuge to produce high-quality Crude Palm Oil (CPO). Optional downstream expansion:
Crude Palm Oil → Continuous Refining (degumming, deacidification, bleaching, deodorization) → Fractionation (Palm Olein / Palm Stearin)
1 Main production section equipment
Weighbridge, Fresh Fruit Bunch (FFB) unloading platform, conveyor system, horizontal sterilizer bank, rotary fruit thresher, digester, twin-screw oil press, clarification tank, disc centrifuge, crude oil drying system
2 By-product recovery system
Fiber-nut separator, nut dryer, shell-kernel air separator
3 Utilities (significant investment share)
Biomass steam boiler + steam turbine generator set (self-powering solution)
Circulating cooling water system, water purification system
Crude palm oil storage tank farm (large plants typically maintain 3,000–10,000 m³ capacity), palm kernel warehouse
4 Environmental protection system [Mandatory for approval]
POME (Palm Oil Mill Effluent) treatment system (major environmental challenge in the industry)
Anaerobic fermentation of wastewater produces biogas for boiler combustion; simple solution: multi-stage anaerobic ponds; high-standard configuration: biogas power generation.
Solid waste: EFB (Empty Fruit Bunches), fiber, and shells are collected and utilized.
30 t/h FFB large-scale pressing line: Complete equipment set $6 million – $12 million
45–60 t/h fully automated large-scale pressing line: $15 million – $32 million
