400 Slotted Vertical Hydraulic Oil Press Machine

The 400 Slotted 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 slotted series features a pressing chamber with narrow, elongated oil drainage openings. During hydraulic compression, separated oil flows through these openings and is directed toward the collection area.

The manufacturer's product range includes different chamber diameters, single-chamber and dual-chamber arrangements, bottom-discharge models, and selected automatic cake discharge configurations.

Customers can select a suitable machine configuration according to their raw materials, processing requirements and installation conditions.

⚙️ Product Highlights

400 Series | Slotted Pressing Chamber | 3 kW Listed Power | Multiple Chamber Sizes | Single / Dual Chamber | Bottom / Automatic Cake Discharge

🔧 Key Features

1. Slotted Pressing Chamber Structure

The pressing chamber features elongated drainage openings along the chamber wall. These openings provide passages for separated oil to flow out during hydraulic pressing.

Compared with a round-hole pressing chamber, the slotted structure uses a different drainage opening design. The appropriate chamber type should be selected according to the characteristics of the oil-bearing material and the intended processing conditions.

2. Multiple Pressing Chamber Sizes

The manufacturer's technical materials list three chamber diameters for the 400 slotted series:

• 330 mm

• 390 mm

• 475 mm

Available chamber heights include 800 mm and selected 1200 mm configurations. The available diameter and height combinations depend on the specific machine arrangement.

3. Single and Dual Chamber Arrangements

The 400 slotted series includes single-chamber and dual-chamber configurations.

Different arrangements can be considered according to the required operating process, available installation space and material handling requirements.

4. Bottom and Automatic Cake Discharge

The manufacturer's product range includes both bottom-discharge and automatic cake discharge configurations.

Bottom-discharge models are listed with 800 mm pressing chambers.

Selected automatic-discharge models are equipped with three hydraulic cylinders, including a smaller 200-series cylinder, according to the manufacturer's technical materials.

The exact discharge mechanism and operating sequence should be confirmed for the selected machine configuration.

5. Hydraulic Batch Pressing Process

The hydraulic system applies pressure to prepared oil-bearing materials inside the vertical pressing chamber.

As the material is compressed, separated oil passes through the slotted drainage openings and flows toward the collection area.

After the pressing cycle, the remaining press cake is removed through the machine's designated discharge arrangement.

🌻 Oilseed Processing Applications

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

Depending on the characteristics of the raw material, 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 seeds 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 slotted 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 elongated drainage openings in the slotted chamber and is directed toward the collection area.

Step 5: Press Cake Discharge

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

🛠️ Operation & Maintenance

Proper operation and regular maintenance help maintain the machine's operating condition.

• Inspect visible hydraulic connections and components before operation.

• Check the slotted drainage openings for residue or blockage.

• Prepare raw materials according to the manufacturer's 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 manufacturer's instructions when operating the cake discharge system.

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

❓ Frequently Asked Questions

Q1. What is the difference between the 400 round-hole and 400 slotted hydraulic oil press?

The main difference is the pressing chamber drainage structure. The round-hole model uses circular drainage openings, while the slotted model uses elongated openings. The appropriate chamber type depends on the raw material and processing conditions.

Q2. What pressing chamber sizes are available for the 400 slotted series?

The manufacturer's listed configurations include chamber diameters of 330 mm, 390 mm and 475 mm. Chamber heights include 800 mm and selected 1200 mm arrangements.

Q3. Is the 400 slotted model available with two pressing chambers?

Yes. The manufacturer's product materials list both single-chamber and dual-chamber configurations for the 400 slotted series.

Q4. Does the machine support automatic cake discharge?

Selected 400 slotted configurations include automatic cake discharge. According to the manufacturer's technical materials, these models use three hydraulic cylinders, including a smaller 200-series cylinder.

Q5. What is the production capacity of the 400 slotted hydraulic oil press?

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.

Q6. Can this machine process different types of oilseeds?

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

Q7. How can I choose between bottom discharge and automatic cake discharge?

The choice depends on the required operating process, chamber configuration and material handling requirements. Please contact us with your processing needs so that the available configurations can be reviewed.
