What should we consider when choosing a plate and frame filter press?

When selecting a Plate & Frame filter press, consider: 1) Material characteristics such as particle size and filterability, 2) Production requirements including batch size and cycle time, 3) Filtration goals such as clarity or cake dryness, 4) Operational environment including temperature and chemical compatibility, and 5) Budget considerations, balancing initial investment with long-term operational costs.

Precision Filtration & Polishing: The Plate and Frame Filter Press

Q: What is the main difference between Plate & Frame and Recessed Chamber filter presses?

Recessed Chamber filter presses are designed for dewatering and are easier to automate. Plate & Frame filter presses are designed for polishing filtration where extremely clear filtrate or filter paper is required. If your priority is ultra-high clarity or removing very fine particles such as activated carbon, Plate & Frame is the preferred choice.

Q: Can I use filter paper with this machine?

Yes. This is the key advantage of the Plate & Frame design. The flat backup plate provides stable support for filter paper or high-density filter pads, achieving filtration precision down to 1 micron—something standard filter cloth cannot achieve.

Q: Can you provide a steam jacketed version for hot filtration?

Yes. For applications such as viscous oil, wax, or gelatin, we can manufacture cast iron plates with internal hollow channels. These allow steam or hot water to circulate inside the plates, keeping materials hot and preventing them from solidifying during filtration.

Q: Is this machine fully automatic?

Typically, Plate & Frame filter presses are manual or semi-automatic. Because the frames are separate and the filter paper is delicate, full automatic plate shifting is not practical. However, hydraulic automatic closing and pressure-holding systems can be equipped to reduce operator labor.

Q: Can I change the cake thickness?

Yes. Cake thickness is adjustable. Unlike recessed chamber plates with fixed depth, Plate & Frame presses allow you to swap hollow frames for thicker or thinner ones, such as changing from 25 mm to 40 mm, without replacing the entire machine.

Engineered for industries requiring maximum filtrate clarity. Featuring a versatile "Plate + Frame" design compatible with filter paper and fine pads. Available in Stainless Steel (GMP) and Cast Iron for high-value applications.

The Specialist for Fine Separation

For project managers seeking absolute purity, the choice of equipment is critical. While recessed presses handle bulk sludge, LOWAY EQUIPMENT’s Plate and Frame Filter Press stands as the proven solution for precision filtration and liquid polishing.

Unlike standard dewatering machines, our Plate & Frame design allows for the use of Filter Paper or High-Density Pads. This makes it capable of capturing ultra-fine particles (down to 1 micron) that pass through standard filter cloths. From edible oil fractionation to pharmaceutical serum clarification, this machine delivers the crystal-clear filtrate your process demands.

How It Works

The machine consists of alternating Solid Plates and Hollow Frames, aligned on a skeleton. The filter medium (Cloth or Paper) is sandwiched between them.

1. Clamping:

The hydraulic system compresses the plate pack to seal the frames.

2. Feeding:

Slurry is pumped into the hollow frames. The frame thickness determines the cake volume.

3. Filtration:

Liquid passes through the filter paper/cloth and drains down the solid plate surface. Solids are trapped inside the frame.

4. Discharge:

The press is opened, and the operator separates the plates/frames to discharge the cake or replace the filter paper.

Discharge Options:

Open Delivery: Visible spigots for monitoring filtrate clarity from each chamber.
Closed Delivery: Piped manifold for volatile, toxic, or hygienic fluids.

Why Choose Plate & Frame?

The only design compatible with Filter Paper, essential for ultra-fine filtration, where cloth is not enough.

We manufacture frames in Stainless Steel (304/316L) for Pharma/Food, Cast Iron for High-Temp Oil, and Reinforced PP for general chemical use.

Easily scale your batch size up or down by simply adding or removing frames and plates.

Achieves the highest filtrate clarity of any pressure filter type, making it ideal for final product polishing.

Frequently Asked Questions

Have More Questions? Our technical team is ready to provide detailed, personalized guidance.

Q1: What is the main difference between "Plate & Frame" and "Recessed Chamber" filter presses?

Recessed Chamber presses are designed for “Dewatering” (making solids dry) and are easier to automate. Plate & Frame presses are designed for “Polishing” (making liquid clear) or for handling materials that require Filter Paper. If your priority is ultra-high filtrate clarity or removing fine activated carbon, choose Plate & Frame.

Q2: Can I use Filter Paper with this machine?

Yes. This is the primary advantage of the Plate & Frame design. The flat backup plate provides perfect support for filter paper or high-density filter pads, allowing for filtration precision down to 1 micron, which filter cloth alone cannot achieve.

Q3: Can you provide a "Steam Jacketed" version for hot filtration?

Yes. For applications like viscous oil, wax, or gelatin filtration, we manufacture Cast Iron plates with hollow internal channels. This allows steam or hot water to circulate through the plates, keeping the product liquid and preventing it from solidifying during filtration.

Q4: Is this machine fully automatic?

Generally, Plate & Frame presses are Manual or Semi-Automatic. Because the frames are separate from the plates and filter paper is delicate, automatic plate shifting is difficult. However, we do equip them with Hydraulic Automatic Closing and pressure maintenance to reduce operator labor.

Q5: Can I change the cake thickness?

Yes. Unlike recessed plates which have a fixed depth, with a Plate & Frame press, you can simply swap out the Hollow Frames for thicker or thinner ones (e.g., changing from 25mm to 40mm) to adjust the cake volume without buying a whole new machine.

Q6: What shall we consider when choosing a plate and frame filter press?

When choosing a plate and frame filter press, consider:

Material Characteristics: Particle size, solids concentration, filterability
Production Requirements: Batch size, cycle time, automation needs
Filtration Goals: Cake dryness, filtrate clarity, throughput
Operation Environment: Temperature, chemical compatibility, space constraints
Budget Considerations: Initial investment vs. operational costs
