Groundnut Oil Production Line Equipment Selection And Maintenance Guide

A well-designed groundnut oil production line can greatly increase your profitability and operational efficiency. Our groundnut oil processing equipment is widely popular in Nigeria, Vietnam, India, South Africa, Thailand, Central Asia, and parts of the Middle East—trusted by small workshops and large-scale factories alike for its reliability and efficiency. If you’re starting a new groundnut oil processing plant or upgrading existing equipment, this guide simplifies selection and maintenance to drive your success.

How To Choose The Right Groundnut Oil Production Line Equipment

Selecting equipment depends on your production capacity, budget, and target market requirements. Below is a detailed table of core equipment, parameters, and selection criteria to ensure optimal performance:

Core Process	Equipment Name	Selection Reference (Capacity Match)	Common Troubleshooting
Pretreatment	Cleaning Sieve	1-5 t/h (Small), 5-20 t/h (Medium)	Screen Clogging: Clean screen, adjust vibration angle
Pretreatment	Sheller	Matches the subsequent cooker capacity	Poor Kernel-Shell Separation: Adjust rubbing gap
Pretreatment	Crusher / Flaking Mill	Matches the extractor capacity	Uneven Flaking: Adjust roller pressure, check feed rate
Pretreatment	Cooker	1-5 t/h (Small), 5-20 t/h (Medium)	Burnt Material: Reduce temperature, adjust stirring
Oil Extraction (Pressing)	Screw Oil Press	1-3 t/h (Small), 3-10 t/h (Medium)	Low Oil Output: Check barrel temperature, clean screw
Oil Extraction (Solvent)	Extractor	10-50 t/h (Large)	Incomplete Extraction: Extend time, check solvent ratio
Oil Extraction (Solvent)	Evaporator + Stripper	Matches the extraction capacity	High Solvent Residue: Increase temperature, check seals
Refining	Degumming Tank	Same as the degumming capacity	Poor Gum Separation: Adjust acid dose, extend time
Refining	Deacidification Tank	Same as degumming capacity	High Acid Value: Increase alkali dose, check temperature
Refining	Bleaching Tower	Matches refining capacity	Poor Bleaching: Replace active clay, adjust temperature
Refining	Deodorizing Tower	Matches refining capacity	Odor Remains: Extend deodorization time, check vacuum seals
Refining	Plate Filter Press	Matches deodorizer capacity	Matches the cleaning sieve capacity

Key selection tips:  

• For small businesses (daily output ≤5t), choose a compact peanut oil machine set with a screw press—cost-effective and easy to operate.  
• Medium factories (5-20t/day) should opt for integrated pretreatment + press + refining equipment to improve efficiency.  
• Large-scale groundnut oil processing plants (≥10t/day) may consider solvent extraction lines for higher yield and continuous production.  
• Prioritize equipment made of 304 stainless steel to meet FDA and EU food safety standards for export markets.

Essential Maintenance Tips For Groundnut Oil Processing Machine

Proper maintenance extends equipment life, reduces downtime, and maintains consistent performance. Follow these practical tips:

Daily Maintenance

Clean the cleaning sieve’s screen and the press chamber of the groundnut oil extraction machine after each shift to prevent residue buildup. Check the cooking pot’s stirring blade for wear and adjust if needed. Ensure all electrical connections are tight to avoid short circuits.  

Regular Component Checks  

1. Replace the filter cloth in the plate-and-frame filter every 3-6 months (or sooner if filtration speed drops).  
2. Inspect the screw and wear on the oil press machine or monthly—our high-quality alloy screws last 50% longer than standard versions but require lubrication with food-grade oil every 2 weeks.  
3. Check the deodorization tower’s vacuum seal quarterly to maintain -0.095MPa pressure, critical for odor removal.  

Troubleshooting Prevention

Address minor issues promptly: If the oil yield drops, check the cooking temperature (105-110℃ is optimal) and clean the press screw. For poor bleaching results, replace the activated clay and adjust the temperature to 100-110℃.  

Annual Servicing

Schedule a professional inspection of gears, motors, and pressure vessels to identify potential problems. Our team provides detailed maintenance manuals and 24/7 technical support.
