DHZ470 Biodiesel Glycerin Separation 3-Phase Disc Oil Separator Sliding Piston Auto Discharge 37KW Motor

DHZ470 Biodiesel Glycerin Separation 3-Phase Disc Oil Separator

The DHZ470 disc oil separator is purpose-engineered for the biodiesel production industry, providing high-efficiency separation of crude glycerin from biodiesel. Utilizing a sliding piston automatic discharge mechanism, this 3-phase disc stack separator delivers continuous operation with minimal downtime, ensuring maximum productivity in commercial biodiesel plants.

Biodiesel Glycerin Separation Process

After the transesterification reaction, the reaction mixture contains biodiesel (methyl esters), crude glycerin, and catalyst residues. The DHZ470 disc separator separates these components continuously under high centrifugal force. The heavier glycerin phase settles at the bowl periphery and is discharged through the heavy liquid outlet, while the lighter biodiesel phase flows through the disc stack and exits via the light liquid centripetal pump. Suspended solids and catalyst soap residues are automatically discharged through the sliding piston mechanism at programmable intervals.

Key Features

• Sliding piston automatic discharge eliminates manual cleaning stops, enabling 24/7 continuous operation

• All product contact parts manufactured from food-grade SUS304 stainless steel
• 37KW main motor with ABB VFD for precise bowl speed control
• PLC touch screen control system with recipe storage for different biodiesel feedstocks
• SKF premium bearings ensure continuous operation with maintenance intervals of 8,000+ hours
• Adjustable centripetal pumps allow fine-tuning of interface position for maximum yield
• Compact footprint fits standard biodiesel plant layouts
