ZX/ZY 28 Large-Scale Oil Press
The ZX/ZY 28 screw oil press is a high-capacity, continuous oil extraction machine designed for medium to large-scale oil mill plants. It is suitable for processing high-oil-content seeds such as cottonseed, rapeseed, castor seed, sunflower seed, palm kernel, peanut, and soybean. This robust and durable oil press is widely used in the full pressing and pre-pressing processes of plant oil production lines.
The ZX/ZY 28 employs advanced spiral pressing technology to ensure high efficiency, low energy consumption, and minimal maintenance costs. Its unique design produces loose yet structurally sound cake, making it ideal for solvent extraction in integrated oil extraction processes. With a notably low residual oil rate in the cake, this oil press maximizes output and profitability for commercial oil producers.
