Hydraulic Oil Press for Sesame Oil

Hydraulic Oil Press Guide: Sesame Oil Hot Press & Other Oilseed Options

Producing high-quality oil requires understanding seed type and hydraulic press operation. Sesame oil is unique: it must be hot-pressed in a 300mm small barrel, with a batch of 30kg and no pre-pressing. Other oilseeds, such as peanuts, sunflower, or soybean, can be cold-pressed or hot-pressed in the same 300mm barrel. For these seeds, you can pre-press and fill up to 60kg per barrel for higher efficiency. This guide provides step-by-step instructions, pressure settings, and operational tips based on real production experience.

Why Use a Hydraulic Oil Press?

Compared with Korean-style hydraulic oil presses, our 300mm barrel system allows larger batch sizes. Sesame oil batches can hold 30kg without pre-pressing, while other oilseeds can be pre-pressed and loaded up to 60kg per barrel. This higher capacity improves production efficiency and reduces the number of pressing cycles needed for the same output.

Hydraulic oil presses apply high pressure to extract oil efficiently while preserving nutritional content. They allow precise control, are suitable for small or industrial production, and adapt to different seeds by adjusting batch size, pre-pressing, and pressing mode.

• Sesame oil: 300mm barrel, 30kg batch, hot-press only, no pre-press
• Other seeds: 300mm barrel, pre-press allowed, batch up to 60kg, cold or hot press
• Pressure: 55–60MPA for optimal extraction
• Pressing time: Sesame ~30–40 minutes; other seeds vary depending on type and batch

Hot Pressing Sesame Oil

1. Preparing Sesame Seeds

• Clean seeds to remove dust and impurities
• Roast seeds evenly to enhance aroma and yield
• Keep moisture low to avoid steaming
• Do not pre-press sesame seeds

2. Loading the 300mm Barrel

• Fill the barrel with ~30kg of roasted sesame seeds
• Ensure even distribution; no pre-pressing
• Do not exceed 30kg to prevent clogging or machine damage

3. Hot Pressing Procedure

• Start at low pressure, gradually increase to 55–60MPA
• Press for 30–40 minutes per batch
• Observe oil flow; adjust if necessary for even extraction
• Collect oil continuously in a clean container

4. Filtering and Storing Sesame Oil

• Filter oil using fine mesh or filter cloth
• Let oil settle 24–48 hours for clarity
• Store in sealed, clean containers away from sunlight

Cold or Hot Pressing Other Oilseeds

Other oilseeds like peanuts, sunflower, and soybeans can be cold-pressed or hot-pressed in the same 300mm barrel. For these seeds, pre-pressing allows the operator to load up to 60kg per barrel, increasing efficiency while maintaining smooth oil flow.

• Pre-press seeds lightly to compact them
• Fill barrel up to 60kg for larger batch processing
• Maintain pressure at 55–60MPA
• Pressing time varies by seed type and batch size
• Filter and store oil similarly to sesame oil

Choosing Barrel Size and Pressure

• Sesame oil: 300mm, 30kg, hot press, no pre-press
• Other seeds: 300mm, 60kg with pre-press, hot or cold press
• Pressure: 55–60MPA, gradually increased from low to high
• Batch selection depends on seed type and production scale

Maintenance and Safety

• Clean barrels and pressing keys after each batch
• Check hydraulic oil levels and gauges regularly
• Wear gloves and safety glasses
• Do not exceed recommended barrel capacity or pressure
• Perform routine maintenance to ensure long machine life

Benefits of Proper Hydraulic Press Operation

• Maximized oil yield for sesame and other seeds
• Preserved nutritional content and aroma
• Flexible batch sizes using the same 300mm barrel
• Durable, easy-to-operate hydraulic system
• Prevents clogging and ensures smooth oil flow

Frequently Asked Questions (FAQ)

Q1: Can I pre-press sesame seeds?
No, sesame seeds must be hot-pressed without pre-pressing.

Q2: What batch size is best for sesame oil?
30kg per 300mm barrel is optimal.

Q3: Can other seeds be pre-pressed?
Yes, other seeds can be pre-pressed and loaded up to 60kg in the 300mm barrel.

Q4: How long should a sesame hot press batch take?
Typically 30–40 minutes.

Q5: How do I maximize oil yield for other seeds?

Pre-press seeds, fill evenly, and apply pressure gradually from low to high.
