Introduction

Choosing the right hydraulic oil press is a critical investment decision that directly impacts your production capacity, oil yield, and overall profitability. With multiple models available, understanding the key differences between them is essential for making an informed choice.

Key Factors to Consider

1. Raw Material Type

  • Conventional seeds: sesame, peanut, rapeseed, soybean, tea seed
  • Hard-shell materials: walnut, almond, apricot kernel, tiger nut
  • Cold-press only: materials requiring low-temperature extraction

2. Production Scale

  • Small-scale: 500-1,500 kg/day
  • Medium-scale: 1,500-3,000 kg/day
  • Large-scale: 3,000+ kg/day

3. Pressing Method

  • Hot pressing: higher yield, faster cycle time (30-40 minutes/batch)
  • Cold pressing: premium quality oil, longer cycle time (2 hours/batch)

Model Comparison

HN480 High Pressure Hydraulic Oil Press

The HN480 bridges the gap between the HN426 and HN500, offering balanced performance for both conventional and cold-press applications.

Best For:

  • Mixed production requirements
  • Medium-to-large operations
  • Both conventional and cold-press materials

Key Specifications:

  • 560-ton pressing force
  • 72 Mpa system pressure
  • 48 Mpa/cm2 cake surface pressure
  • 100 kg batch capacity

HN500 Ultra High Pressure Hydraulic Oil Press

The HN500 is our flagship model, designed for the most demanding industrial applications with maximum pressing power.

Best For:

  • Large-scale industrial operations
  • Toughest cold-press materials
  • Maximum oil yield requirements

Key Specifications:

  • 620-ton pressing force
  • 75 Mpa system pressure
  • 52 Mpa/cm2 cake surface pressure
  • 100 kg batch capacity

Selection Decision Tree

Step 1: Determine Your Primary Material

Conventional seeds only:

  • Small scale -> HN325
  • Medium scale -> HN355
  • Large scale -> HN500

Cold-press materials:

  • Standard cold press -> HN426
  • High-volume cold press -> HN480
  • Maximum yield cold press -> HN500

Mixed materials:

  • Balanced performance -> HN480
  • Maximum versatility -> HN500

Single vs Double Barrel Configuration

Single barrel:

  • Lower upfront cost
  • Simpler operation
  • Ideal for small-scale or startup operations

Double barrel:

  • Nearly doubles throughput
  • Continuous operation capability
  • Recommended for commercial and industrial use
