400 Round-Hole Vertical Hydraulic Oil Press Machine

The 400 Round-Hole Vertical Hydraulic Oil Press Machine is part of the vertical hydraulic oil pressing equipment range offered by GOOD OIL PRESS. Designed for batch oil extraction, the machine uses hydraulic pressure to compress properly prepared oil-bearing materials inside a vertical pressing chamber.

The 400 series features a round-hole pressing chamber structure. During the pressing process, separated oil flows through small circular drainage openings in the chamber wall and is directed toward the oil collection area.

The manufacturer's product range includes different chamber diameters, single-chamber and dual-chamber arrangements, and additional configurations for different operating requirements. Customers can select a suitable machine according to their raw materials, processing needs and installation conditions.

🔧 Key Features

1. Round-Hole Pressing Chamber Design

The pressing chamber is equipped with circular drainage openings along the chamber wall. During hydraulic compression, separated oil passes through these openings and flows toward the collection area.

The round-hole structure is one of the pressing chamber designs available in the manufacturer's vertical hydraulic oil press range. The appropriate chamber type should be selected according to the characteristics of the oil-bearing material and the intended processing conditions.

2. Six Pressing Chamber Diameter Options

The manufacturer's technical materials list six pressing chamber diameters for the 400 round-hole bottom-discharge series:

• 330 mm

• 390 mm

• 420 mm

• 450 mm

• 475 mm

• 500 mm

These chamber options allow customers to discuss suitable equipment configurations according to their batch processing requirements and material characteristics.

3. Single and Dual Chamber Configurations

The 400 round-hole bottom-discharge series includes single-chamber and dual-chamber arrangements in the manufacturer's product materials.

The appropriate arrangement depends on the customer's operating process, available installation space and material handling requirements.

4. Hydraulic Pressing System

The machine uses a hydraulic system to apply pressing force to the prepared material inside the vertical chamber.

As the material is compressed, oil is separated and flows through the circular drainage openings. The remaining solid material forms a press cake that is removed after the pressing cycle.

5. Different Equipment Configurations

In addition to the bottom-discharge models described on this page, the manufacturer's wider 400 round-hole range includes selected configurations with different chamber heights and automatic cake discharge arrangements.

These configurations should be evaluated separately because their chamber combinations, hydraulic arrangements and machine dimensions may differ.

🌻 Oilseed Processing Applications

Vertical hydraulic oil presses can be considered for batch processing of suitably prepared oil-bearing materials.

Depending on the raw material characteristics, pretreatment process and selected equipment configuration, potential applications may include:

• Peanuts: Hydraulic pressing of appropriately prepared peanut materials.

• Sesame Seeds: Batch oil extraction applications involving prepared sesame seeds.

• Walnut Kernels: Processing of suitably prepared walnut kernels.

• Other Oil-Bearing Materials: Additional compatible oilseeds and kernels subject to technical evaluation.

Application Note: Oilseed compatibility depends on material characteristics, moisture content, pretreatment method and pressing conditions. The suitability of a specific material for the 400 round-hole configuration should be confirmed before purchase.

🔄 Working Principle

Step 1: Raw Material Preparation

Clean and prepare the oil-bearing materials according to the required processing method.

Step 2: Chamber Loading

Load the prepared material into the vertical pressing chamber according to the machine's operating instructions.

Step 3: Hydraulic Compression

The hydraulic system applies pressure to compress the prepared material inside the pressing chamber.

Step 4: Oil Drainage and Collection

Separated oil flows through the circular drainage openings in the chamber wall and is directed toward the collection area.

Step 5: Press Cake Removal

After the pressing cycle is completed, the remaining press cake is removed through the designated bottom-discharge arrangement.

🛠️ Operation & Maintenance

Proper operation and regular maintenance are important for hydraulic oil pressing equipment.

• Inspect visible hydraulic connections and components before operation.

• Check the pressing chamber and circular drainage openings for residue or blockage.

• Prepare raw materials according to the manufacturer's operating recommendations.

• Follow the specified pressing sequence and pressure settings.

• Clean the pressing chamber and oil-contact surfaces after operation.

• Inspect hydraulic seals and other service components at recommended intervals.

• Follow the equipment manual when performing inspection or maintenance.

Safety Reminder: Only trained personnel should operate or maintain the machine. Hydraulic components must be safely depressurized before inspection or servicing.

❓ Frequently Asked Questions

Q1. What is the difference between the 340 and 400 hydraulic oil press series?

The manufacturer's listed hydraulic cylinder outer diameter is 340 mm for the 340 series and 400 mm for the 400 series. Available chamber configurations may also differ. The appropriate machine should be selected according to confirmed specifications and processing requirements.

Q2. What is the difference between round-hole and slotted pressing chambers?

The main difference is the drainage opening structure. Round-hole chambers use circular openings, while slotted chambers use elongated openings. The appropriate chamber design depends on the raw material and processing conditions.

Q3. What chamber sizes are available for the 400 round-hole series?

The listed bottom-discharge configurations include chamber diameters of 330 mm, 390 mm, 420 mm, 450 mm, 475 mm and 500 mm, with an 800 mm chamber height.

Q4. Is the 400 round-hole series available with two pressing chambers?

Yes. The manufacturer's product materials list single-chamber and dual-chamber arrangements for the 400 round-hole bottom-discharge series.

Q5. Does the wider 400 round-hole range include automatic cake discharge?

Selected configurations in the manufacturer's wider 400 round-hole range include automatic cake discharge arrangements. These models should be evaluated separately from the bottom-discharge configurations described in the technical table above.

Q6. What is the production capacity of the machine?

Actual processing capacity depends on the raw material, pretreatment method, chamber dimensions, operating conditions and selected configuration. Please contact us with your requirements for a technical evaluation.

Q7. Can this machine process different types of oilseeds?

Hydraulic oil pressing equipment may be suitable for different prepared oil-bearing materials. The compatibility of a specific material with the 400 round-hole configuration should be confirmed before ordering.
