Mech Tech Steel Industries offers the Vertical Pressure Leaf Filter (VPLF), a highly efficient, closed-loop filtration system designed for the clarification of liquids with low solid content. This system is the industry standard for “Polishing Filtration,” providing a superior alternative to traditional plate and frame filters by offering higher flow rates and significantly lower maintenance costs.

The VPLF consists of a vertical pressure vessel with internally mounted rectangular filter leaves. Each leaf is constructed with multi-layered stainless steel wire mesh, ensuring precise filtration and a clear filtrate every time.

Closed-Loop System: The fully enclosed pressure vessel ensures a leak-proof operation, preventing environmental contamination and protecting operators from hazardous fumes or liquids.
Multi-Layered Filter Leaves: High-quality stainless steel (SS 316L) 5-layer or 7-layer mesh leaves provide excellent mechanical strength and filtration accuracy.
Automated Cake Discharge: Equipped with a pneumatic vibrator system for the rapid and easy discharge of the filter cake, reducing manual labor and downtime.
Compact Vertical Design: Saves valuable floor space while providing a large filtration area, making it ideal for modern processing plants.
cGMP & Industrial Standards: Built with premium materials (SS 304/316/316L) to meet the rigorous hygiene requirements of the food and pharma industries.

No Filter Cloth Required: Eliminates the recurring cost and hassle of changing filter cloths, as the stainless steel leaves are permanent and easy to clean.
Minimal Product Loss: The vertical design allows for efficient cake drying (using air or steam) before discharge, ensuring maximum liquid recovery.
High Flow Rates: Engineered to handle large volumes of liquid with high precision, improving overall plant throughput.
Low Operational Cost: Minimal moving parts and automated cleaning cycles result in significantly lower maintenance and labor costs compared to manual filters.
Environmentally Friendly: Reduces waste by eliminating disposable filter media and ensuring a clean, contained process.

Edible Oil Industry: Bleaching and dewaxing of vegetable oils (Soya, Sunflower, Palm, etc.).
Chemical Industry: Filtration of resins, sulfur, plasticizers, and organic/inorganic salts.
Pharmaceuticals: Clarification of syrups, antibiotics, and active pharmaceutical ingredients (APIs).
Bulk Handling: Direct integration with big-bag unloading or silos.

Frequently Asked Questions

What are the main advantages of a U-Type design over a Tubular design?

The U-Type design offers much easier access for cleaning and maintenance. Because the top cover is removable, you can clean the entire length of the screw without pulling it out of a tube, which is essential for industries handling multiple products.

Can a U-Type Screw Conveyor handle non-free-flowing materials?

Yes. Due to the torque-efficient design and the ability to use specialized screw flights (like ribbon flights), it is excellent for handling sticky, sluggish, or non-free-flowing materials that might clog other systems.

What is the maximum length you can manufacture?

We can manufacture U-Type conveyors up to 12 meters in length. For longer distances, we use intermediate hanger bearings to ensure the screw remains stable and operates without noise.

Are your conveyors suitable for hot or cold materials?

Absolutely. We can provide Jacketed U-Troughs that allow for the circulation of hot water, steam, or chilled water to maintain a specific temperature while the material is being moved.

How do you ensure the system is dust-tight?

We use high-grade food-grade silicone or neoprene gaskets between the U-trough and the top cover. Combined with precision-bolted flanges, this ensures that no fine powder escapes during operation.
