In the palm oil refining and fractionation process, the crystallization stage directly determines the purity and quality of the final product. Our palm oil crystallization tanks are specifically designed for the efficient and precise separation of palm stearin and palm gum, enhancing the added value of the oil.
Core Features
• High-efficiency heat exchange structure : The advanced hollow spiral ribbon stirring structure and large-area cooling coil design greatly increase the heat exchange area and heat transfer coefficient, ensuring that the grease is heated and cooled evenly in the tank.
• Intelligent temperature control system : Equipped with a variable frequency stepless speed regulation device and a PLC intelligent temperature control system, it can monitor and precisely adjust the cooling rate and stirring speed (3-8 r/min) in real time, perfectly matching the palm oil crystallization curve.
• Sanitary-grade precision manufacturing : The inner wall of the tank is treated with high-precision mirror polishing (Ra≤0.4μm), and is equipped with sanitary quick-opening interface, cleaning ball and special sanitary mechanical seal to ensure zero contamination of materials during processing and fully comply with GMP food safety production verification requirements.
• No dead corners design : The optimized tank structure and bottom stirring blade design effectively prevent oil residue in dead corners, avoid cross-contamination between batches, and ensure the purity of every drop of oil.
Product Advantages
• Superior crystal quality : Precise temperature control (±0.5℃) and uniform slow stirring promote slow growth of crystal nuclei, resulting in large, highly spherical crystal particles with strong resistance to mechanical stress, laying a perfect foundation for subsequent membrane filtration separation and significantly improving separation efficiency.
• Significant energy saving and consumption reduction : The optimized cooling circulation system, combined with high heat transfer efficiency, can quickly and accurately cool the refined oil from 60°C to the target crystallization temperature, which greatly shortens the production cycle and reduces operating energy consumption while ensuring fractionation accuracy.
• Easy and worry-free maintenance : The fully enclosed stainless steel tank and sanitary quick-opening design make daily cleaning and equipment maintenance extremely convenient, effectively extending the service life of the equipment and reducing long-term operating costs.
