How to choose a suitable commercial oil press machine?

মে 08,2025

In the oilseed processing industry, ​commercial oil press machines​ have become indispensable equipment due to their high efficiency and versatility.

This article provides a technical breakdown of four mainstream types—hydraulic, fully automatic, peanut-specific, and semi-automatic models—analyzing their specifications, working principles, and ideal applications to guide businesses in selecting optimal equipment.

​Technical comparison of commercial oil press machines​

The ​​hydraulic oil press (6YZ series)​​ operates at 55MPa ultra-high pressure with electric heating, offering batch processing capacities ranging from 2-4kg to 7-18kg. Its integrated separator reduces impurities to <0.3%, making it ideal for high-value seeds like sesame.

The ​​fully automatic screw press (6YL series)​​ achieves continuous production with vacuum filtration, delivering up to 350kg/h throughput and 5-8% higher oil yield than semi-automatic models.

For peanut processing, the ​​ZY-150 model​​ features a dual-stage cold-press mechanism (125mm + 80mm screws) that preserves heat-sensitive nutrients like vitamin E, boosting yield to 48%.

Key data highlights:

  • The ​​6YZ-260 hydraulic press​​ processes 10kg of sesame in 25 minutes.
  • The ​​6YL-125 automatic model​​ handles 300kg/h of rapeseed.
  • Semi-automatic machines (40-60kg/h) support diesel power, ideal for off-grid operations.

​Working principles & material compatibility​

​Hydraulic presses​​ use 1,600–3,000kN piston pressure and 70–100°C preheating for low-temperature extraction, ideal for nuts with >40% oil content (e.g., almonds, sesame). ​​Automatic screw presses​​ employ progressive spiral compression with triple filtration, reducing residual oil in rapeseed cakes to <6%.

The ​​peanut-specific ZY-150 model​​ combines coarse (125mm screw) and fine (80mm screw) pressing stages. Tests show optimal performance at 5–8% moisture content and 110°C, processing 200kg peanuts in 45 minutes.

​Application scenarios & selection guide​

  • ​Startups​​: opt for the ​​6YL-80 automatic press​​ with 80–120kg/h capacity, paired with a centrifugal filter for a compact production line.
  • ​Large factories​​: combine the ​​6YL-125​​ (bulk processing) and ​​6YZ-320​​ (premium sesame oil) to achieve 8+ tons/day throughput.
  • ​Case study​​: an Angolan client using the ​​ZY-150​​ for soybeans achieved 5 tons/day by adjusting screw clearance to 0.8mm and maintaining 95°C preheating, cutting energy costs to 0.12kWh/kg.

​Key considerations for buyers​

When investing in a ​​commercial oil press machine​​, prioritize material testing (oil yield, cake residue, temperature stability) which reduce maintenance costs by 30%. Always verify certifications (CE, ISO) and after-sales support for long-term ROI.
