Small-to-medium scale oil mills often grapple with maximizing oil yield while maintaining operational stability and controlling energy consumption. The ZY24 (202-3) spiral oil press is engineered precisely to tackle these challenges, combining optimized mechanical design with process control to deliver consistent high performance across a variety of oilseeds, including rapeseed, peanut, and sunflower seeds.
The efficiency of oil extraction directly correlates with how well the raw materials are prepared. Controlling kernel moisture to a target range of 6%–8% effectively balances material pliability and oil fluidity during pressing. Excess moisture (>10%) risks lowering oil yield by forming emulsions, while overly dry kernels (<5%) can cause equipment wear and lower extraction efficiency.
Crushing size also plays a pivotal role — aiming for particle sizes between 1.5 and 3 mm offers an optimal balance, increasing the surface area for oil release without blocking screw channels. The ZY24(202-3) supports adjustable crushing configurations to accommodate specific seed types and impurity levels, facilitating better downstream pressing performance.
Managing key pressing parameters ensures maximal oil extraction without sacrificing oil quality. The pressing chamber pressure should be dynamically adjusted within a range of 12 to 18 MPa depending on the oilseed type. For instance, rapeseed requires a higher pressure (~17 MPa) than sunflower seeds (~13 MPa) to rupture the cellular matrix efficiently.
Temperature control between 85°C and 110°C prevents oil degradation and maintains viscosity levels conducive to extraction. Overheating above 115°C can lead to loss of essential fatty acids and inferior oil taste.
The spiral shaft rotation speed setting on the ZY24(202-3) varies from 30 to 50 RPM, allowing operators to fine-tune throughput against quality and energy consumption. Lower speeds can improve oil yield by increasing compression time but may reduce output volume—finding the sweet spot tailored to local operational needs is essential.
| Oilseed | Moisture % | Pressure (MPa) | Temperature (°C) | Screw Speed (RPM) |
|---|---|---|---|---|
| Rapeseed | 6.5–7.5 | 16–18 | 90–105 | 35–45 |
| Peanut | 7–8 | 14–17 | 85–100 | 38–50 |
| Sunflower Seed | 6–7 | 12–15 | 90–110 | 30–40 |
Experienced operators emphasize the importance of avoiding frequent parameter fluctuations which can lead to oil quality deterioration and equipment wear. For example, rapid temperature spikes tend to cause foaming and clogging issues, reducing machine uptime.
Additionally, inadequate cleaning of the feeding system may cause blockage or contamination affecting product purity. Routine maintenance and monitoring protocols are instrumental in achieving long-term stable performance.
By implementing the ZY24(202-3) spiral oil press solutions, oil mills can boost oil output by up to 10–15% compared to conventional models, while also reducing energy consumption by approximately 12%. This translates into tangible operational cost savings and higher profitability margins.
The adaptability of the machine to diverse oilseed characteristics and the user-friendly parameter interface enable rapid staff training and reduced downtime, ideal for evolving production needs in emerging markets.
Clear visual aids such as flowcharts and parameter dashboards incorporated in operation manuals have proven essential for effective knowledge transfer. The ZY24 (202-3) package includes detailed graphical documentation, enhancing comprehension for technical and managerial staff alike.
Feedback from pilot plants equipped with the ZY24(202-3) demonstrates remarkable improvements in both yield consistency and product clarity. Users report oil output increases from 32% to as high as 37% for rapeseed, underlining the real-world efficacy of these engineering solutions.
