Detailed Process Flow of the HP290 model first press oil press machinery oil expeller

The operation of the HP290 model first press oil press machinery oil expeller is a meticulously engineered sequence designed for maximum efficiency and oil yield. This robust system integrates several critical stages, each optimized to extract oil from various oilseeds with minimal residual oil in the cake.

1. Pre-treatment & Preparation

Before pressing, oilseeds undergo essential pre-treatment. This typically involves cleaning to remove impurities such as dust, stones, and metal particles, often utilizing vibrating screens and magnetic separators. Following cleaning, the seeds are conditioned through cooking or roasting, a process that ruptures cell walls, denatures proteins, and reduces oil viscosity, thereby enhancing oil extraction efficiency. For larger seeds, crushing or flaking may precede cooking to optimize surface area for pressing. This stage is crucial for achieving high oil yields and minimizing wear on the expeller components.

2. Feeding & Conveyance

Conditioned oilseeds are then fed continuously into the expeller's feeding hopper. The HP290 employs an automated feeding mechanism, often utilizing a screw conveyor or elevator, to ensure a consistent and controlled input rate into the pressing chamber. This uniformity is vital for stable operation and maintaining optimal pressure within the barrel, preventing blockages and ensuring a steady flow of material through the pressing stages.

3. Mechanical Pressing (Oil Expelling)

At the heart of the HP290 model first press oil press machinery oil expeller is its robust pressing chamber. Here, a helical screw shaft, fabricated from high-grade alloy steel (e.g., 20CrMnTi, 40Cr for enhanced wear resistance), continuously rotates. As the material moves along the progressively tighter screw flights, immense pressure is generated. The design incorporates a segmented pressing cage, constructed from precision-machined steel bars (e.g., 45# carbon steel, heat-treated for hardness) with narrow gaps, allowing the extracted crude oil to escape while retaining the solid meal. The pressing process often involves multiple stages, with increasing pressure zones to maximize oil removal. This chamber's components are manufactured using advanced techniques:

• Product Materials: Key components like the screw shaft and cage bars are made from specialized alloy steels chosen for their high tensile strength, resistance to abrasion, and fatigue limits.
• Manufacturing Processes:
  • Casting: Certain non-critical structural components and specific cage sections might use high-strength iron casting.
  • Forging: The main shaft and critical screw elements undergo forging to achieve superior grain structure, eliminating internal defects and enhancing overall strength and impact resistance.
  • CNC Machining: Precision CNC machining is applied to the screw flights and cage bars to ensure extremely tight tolerances, critical for efficient pressing and minimizing residual oil. This process guarantees dimensional accuracy and surface finish.
  • Heat Treatment: All wear parts are subjected to advanced heat treatment processes (e.g., quenching and tempering, carburizing) to achieve optimal hardness and wear resistance, significantly extending service life.
• Testing Standards: Manufacturing adheres strictly to international quality management systems such as ISO 9001:2015. Components undergo rigorous material composition analysis, non-destructive testing (NDT), hardness testing (Rockwell/Brinell), and dimensional inspections to meet specified tolerances.

4. Oil & Cake Separation

As the crude oil is expelled through the gaps in the cage, it is collected in a crude oil tank below the pressing chamber. Simultaneously, the de-oiled solid residue, known as oil cake, is discharged from the end of the expeller. The HP290's design ensures efficient separation, producing high-quality crude oil and consistent, low-residual-oil cake, which can be further processed for animal feed or other industrial applications.

5. Initial Filtration (Optional/Integrated)

While not strictly part of the pressing mechanism, many HP290 installations integrate an initial crude oil filtration system, such as a vibratory sieve or plate-and-frame filter press, immediately downstream. This step removes larger solid particles suspended in the crude oil, improving its quality and preparing it for further refining if required.

Advantages in Typical Application Scenarios:

• Energy Saving: Optimized motor efficiency and advanced gear reduction systems significantly reduce power consumption per ton of processed material, translating to substantial operational cost savings for target industries like food processing, biofuel, and oleochemicals.
• Corrosion Resistance: Strategic use of stainless steel and anti-corrosive coatings on contact parts ensures longevity and maintains oil quality, particularly crucial for processing high-acid oilseeds or in humid industrial environments.
• Extended Service Life: Through rigorous material selection, precision manufacturing (forging, CNC), and advanced heat treatments, the HP290's wear parts achieve a service life that often exceeds industry averages, minimizing downtime and replacement costs. Typical service life for critical wear parts can be 2000-3000 operating hours before major overhaul, with the main frame lasting decades.
• Target Industries: Highly suitable for large-scale operations in edible oil refineries, biodiesel production facilities, and specialized chemical extraction plants.

Technical Specifications & Performance Parameters

The performance of the HP290 model first press oil press machinery oil expeller is defined by its superior technical specifications, engineered for industrial-scale efficiency and reliability. Understanding these parameters is crucial for optimizing plant operations and achieving target output.

The "Residual Oil Rate" is a critical metric, directly indicating the efficiency of oil extraction. A lower percentage, such as the 5-8% achieved by the HP290, signifies a higher primary oil yield and better economic returns. The "Pressing Chamber Pressure" within the expeller barrel, reaching several hundred atmospheres, is dynamically controlled by the variable pitch of the screw and the choke ring mechanism, which is continuously monitored and adjusted via the PLC. This precise control over pressure and temperature is paramount for maximizing oil release from the cell structures of various oilseeds while preserving oil quality.
