In the palm oil refining filtration process, even slight pressure fluctuations can directly affect the lifespan of the filter membrane and the final filtration accuracy. Our constant pressure filtration tank is specifically designed to work with core equipment such as plate and frame filters and precision membrane filters. Through its built-in pressure stabilizing and buffering mechanism, it ensures that the oil maintains a constant pressure and flow rate throughout the filtration process, making it a key component for ensuring the clarity of the finished oil and improving filtration efficiency.

Core Features

• High-efficiency pressure stabilization and buffering : The tank's internal structure features a scientifically designed buffer chamber that effectively absorbs and eliminates pressure pulsations and water hammer effects generated by the delivery pump. This ensures that the pressure of the grease entering the filter remains stable within the set range, preventing filter cloth or membrane rupture due to sudden pressure changes.

• Hygienic and precision manufacturing : The tank and all pipes in contact with materials are made of high-quality 304 or 316L food-grade stainless steel. The inner wall is treated with high-precision mirror polishing (Ra≤0.4μm), with minimal flow resistance and no oil residue, completely eliminating secondary pollution during transportation.

• Temperature and pressure resistant design : Equipped with a jacketed insulation system, it can effectively prevent palm oil from solidifying and clogging pipelines at low temperatures. The tank has undergone rigorous pressure testing and can withstand the high temperatures (up to 150℃) and standard working pressure of 0.6MPa during the oil refining process.

• Convenient and quick-installation structure : The entire system uses sanitary quick-installation clamps or flanges for extremely convenient assembly and disassembly. A large-diameter drain valve is installed at the bottom of the tank for easy daily cleaning and emptying of residual impurities.

Product Advantages

• Significantly improves filtration quality : The constant pressure environment allows the oil to pass through the filter medium evenly and smoothly, greatly improving the stability and precision of filtration and ensuring that the produced palm oil is clear and free of impurities.

• Extended lifespan of consumables : Stable fluid delivery significantly reduces hydraulic shock to filter elements, filter cloths and filter membranes, effectively reducing the replacement frequency of precision filtration consumables and significantly saving long-term operating costs.

• Safe, energy-efficient, and easy to maintain : The fully enclosed design prevents grease oxidation and external contamination, while the insulation jacket effectively reduces heat loss. The modular structure makes equipment installation and daily maintenance extremely convenient, perfectly meeting the production requirements of modern cleanrooms.
