Hydraulic vs Screw Press for Sesame Oil

Which Machine Is Better for Sesame Oil Production?

When starting a sesame oil business, one of the most important decisions is choosing between a hydraulic oil press and a screw oil press.

Both machines are widely used in edible oil production, but their working principles and performance for sesame oil are very different.

This guide explains the real engineering differences so you can choose correctly.

---

1️⃣ Working Principle Comparison

Hydraulic Oil Press

• Uses high-pressure hydraulic cylinder
• Static pressing system
• Batch operation
• High pressure concentration
• Low rotation friction

Hydraulic pressure can reach 55–60MPA, allowing strong vertical compression inside a closed chamber.

---

Screw Oil Press

• Continuous mechanical extrusion
• Rotating screw shaft
• Friction-based oil extraction
• Continuous feeding and discharge

Pressure is generated gradually through screw compression.

---

2️⃣ Which Is Better for Sesame?

Sesame seeds are:

• Small particle size
• High oil content
• Sensitive to pressure distribution

Because of this, pressure concentration is critical.

---

Hydraulic Press Advantages for Sesame

✔ Strong vertical pressure

✔ Better oil cake formation

✔ Stable oil yield

✔ Suitable for hot press

✔ Lower mechanical wear

✔ Cleaner oil quality

Sesame must be hot pressed, and hydraulic machines are well suited for batch hot pressing.

For sesame oil production, 300 or 325 hydraulic models with 300mm barrel are recommended.

Single batch capacity: 30kg

Hot press only

No pre-press

---

Screw Press Advantages

✔ Continuous production

✔ Higher throughput per hour

✔ Lower initial cost (small models)

✔ Suitable for large industrial lines

However, for sesame:

• Pressure may not concentrate enough
• Oil cake may contain higher residual oil
• Temperature control depends on friction

---

3️⃣ Oil Yield Comparison (General Industry Experience)

Hydraulic Press:

• Higher pressure concentration
• Typically lower residual oil in cake
• Stable extraction

Screw Press:

• Good for mass production
• Slightly higher residual oil (varies by design)
• Efficiency depends on screw design and operator experience

---

4️⃣ Production Scale Consideration

Small / Medium Oil Workshop

Hydraulic press is ideal:

• Lower structural complexity
• Easy maintenance
• Clear batch production rhythm
• Suitable for premium sesame oil

---

Large Industrial Line

Screw press is commonly selected:

• Continuous operation
• High daily output
• Often combined with refining systems

---

5️⃣ Investment Strategy

If your goal is:

Premium sesame oil

Traditional hot-pressed sesame oil

Small to medium scale production

Lower risk startup

Hydraulic press is generally the safer choice.

If your goal is:

Large volume production

Industrial supply chain

Continuous automated line

Screw press may be suitable.

---

6️⃣ Machine Structure and Durability

Hydraulic press:

• Static compression
• Less internal friction
• Lower wear rate
• Longer structural life
• Rated pressure 60MPA (recommended working 55–60MPA)

Screw press:

• Continuous rotation
• Screw shaft wear
• Requires more frequent maintenance

---

7️⃣ Final Recommendation

For sesame oil specifically:

Hydraulic pressing provides:

• Better pressure control
• Stable oil yield
• Strong cake formation
• Suitable for hot press-only production

Screw pressing provides:

• Higher throughput
• Continuous automation
• Industrial-scale output

Choosing depends on your business model, production scale, and investment plan.

Understanding the structural difference prevents costly equipment mistakes.

FAQ

Which is better for premium sesame oil?

For premium sesame oil, 325 hydraulic oil press is usually the better recommendation than screw pressing.

Which is better for a small shop model?

For a small shop or fresh-oil retail model, Korean type or KHOP small hydraulic models are usually more suitable.

When should I choose a screw press?

Choose a screw press when your target is continuous larger-volume production and you already have the pretreatment route for sesame.
