Zero Hold Up Filter Press

The Zero Hold Up Filter Press is a cutting-edge solution designed for liquid filtration, separating solids from liquids efficiently. Built to meet cGMP and FDA compliance, this filter press is equipped with high-performance options such as gear pumps, centrifugal pumps, or lobe pumps, tailored to specific process needs. Its advanced filtration assembly features a modern design to ensure maximum process efficiency. Components such as perforated screens, filter plates, spacers, and filter pads are meticulously organized to deliver seamless and productive operations.

Applications in Various Industries

The Zero Hold Up Filter Press is widely used for syrup and suspension filtration in the pharmaceutical industry. Beyond pharmaceuticals, it serves diverse industries, including:

• Distilleries
• Food ingredients processing
• Organic chemicals
• Resin manufacturing
• Ink and oil production
• Beverage filtration

Its unique design allows efficient separation of solid cakes from liquid flow. The dome-shaped top facilitates easy removal of the cartridge assembly for cleaning and solid cake disposal. Additionally, the press can accommodate a variety of filter pads to suit different product requirements.

Features and Benefits

• Continuous Filtration Process: Ensures no material is held up within the chamber, achieving complete filtration in a single pass.
• One-Pass Clarity: Offers uniform cake distribution across all plates for consistent results.
• Flexible Filter Media: Supports various pad types to meet the needs of specific applications.
• User-Friendly Design: Simplifies the drying of cakes through air or nitrogen purging.
• Robust Build: Filters toxic, hazardous, and explosive liquids safely with included cake filter aid and solids.

Specialized Usage

The Syrup Filter Press is particularly valuable for achieving absolute filtration of high-value products in the pharmaceutical and nutraceutical industries. It is also extensively used in the beverage industry for filtering aerated drinks and pulp-based beverages with precision. Its ability to handle reverse liquid flow eliminates hold-up, ensuring full load filtration and enhancing efficiency.

For industries requiring precise filtration of sensitive liquids, the Zero Hold Up Filter Press offers an unparalleled solution with reliable performance and compliance with strict quality standards.

Working Principle of Zero Hold Up Filter Press

The Zero Hold Up Filter Press is a specialized filtration system designed to ensure zero retention of liquid within the filter assembly. It operates on a reverse flow principle, which optimizes the filtration process while preventing material loss. Below is an overview of its working principle:

• Inlet and Flow Direction: The unfiltered liquid enters the filter press through the inlet at the bottom of the assembly. This bottom-to-top flow ensures that all the liquid is pushed through the filter media, leaving no residue or hold-up inside the chamber.
• Filtration Process: The liquid passes through perforated screens, filter plates, spacers, and filter pads, which are systematically arranged to trap solid particles and impurities. The filter pads or media separate the solid cake from the liquid, allowing the filtered liquid to pass through while retaining the solids on the pads.
• Reverse Liquid Flow: Unlike traditional filter presses, the Zero Hold Up Filter Press operates on a reverse flow mechanism. This unique design ensures complete utilization of the filter area and prevents any liquid from remaining unfiltered in the chamber.
• Solid Cake Formation: During filtration, solid particles accumulate on the filter pads, forming a uniform cake. This cake can be easily removed after the process for cleaning or further processing.
• Cartridge Assembly and Cleaning: The cartridge assembly is housed within a dome-shaped cover at the top of the filter press. This design allows for easy removal of the assembly, simplifying the cleaning process and the disposal of the solid cake.
• Drying the Cake: After filtration, the cake can be dried using simple air or nitrogen purging, ensuring minimal residual moisture.
• Final Output: The result is a clear, filtered liquid free from solid impurities, with no loss of product due to zero hold-up in the system.
