Large industrial grade high temperature resistant cast iron plate frame Filter Press Machine

Introduction

The large cast iron plate and frame filter press machine is designed for high-pressure, high-temperature filtration applications—especially in agricultural oil pressing operations and industrial fluid purification processes. It is built with ductile cast iron filter plates, offering superior resistance to thermal stress and mechanical load. This makes it particularly effective for hot-pressed oil filtration, such as palm oil, peanut oil, or sunflower oil, where conventional filter presses might fail.
The frame structure is made from heavy-duty cast iron and carbon steel, treated with sandblasting to resist corrosion, deformation, and wear, ensuring long-term stability in demanding environments.
It features an integrated hydraulic system for automatic plate clamping and pressure maintenance, reducing the need for manual operation and improving filtering consistency. The electrical control cabinet supports automatic pressing and pressure retention, with manual functions for cake discharge.
Whether you’re filtering edible oils, gelatin, or industrial liquids with high solid content, this press delivers efficient, stable, and clean results. It is especially suited for rural oil processing plants, small-scale agri-enterprises, or industrial-grade filtration lines that handle heated, viscous liquids.

Machine structure:

• Plate and frame filter press hydraulic system: including hydraulic cylinder, pressure gauge, hydraulic station.
• Filter press frame: The frame material is made of cast iron, which is sturdy and durable with a long service life.
• Electric control cabinet: automatic clamping, automatic pressure maintenance, manual plate opening, manual filter cake unloading.
• Filter plate and filter frame: The filter plate and filter frame are made of ductile iron, which has strong high temperature resistance and is suitable for high-strength cast iron filter plates to filter high-temperature materials.
