Food and Agrochemicals

Many food and agrochemical processes involve catalytic reactions, where solid catalysts must be safely recovered after use. DrM filtration systems provide a closed, automated solution for separating a wide range of catalysts, including pyrophoric materials like Raney nickel or precious metals supported on carbon, silica or bio-mass. The systems support both slurry and dry cake discharge, allow for integrated cake washing, and handle hazardous solids safely. FUNDABAC® filters are widely used for their corrosion-resistant design and automated performance across batch or continuous setups.​

The production of herbicides, insecticides, and fungicides involves multiple filtration stages to remove catalyst residues, reaction byproducts, and formulation solids. DrM candle filters offer high-efficiency separation in a closed system, reducing operator exposure and improving process cleanliness. With flexible discharge modes and compatibility with corrosive and solvent-based streams, they are well-suited for both active ingredient production and downstream clarification.​

Fatty acid production involves hydrogenation of edible oils using solid catalysts such as Raney nickel or Pd-on-carbon. Filtration systems are used to remove these catalysts after reaction, improving product quality and enabling catalyst reuse. Their closed design prevents operator exposure to flammable or pyrophoric solids, and the heel volume filtration feature allows for full batch processing with minimal hold-up. By eliminating precoat stages and simplifying cake discharge, FUNDABAC® systems increase productivity and reduce waste in fatty acid plants worldwide.​

Lactose is a byproduct of dairy manufacturing and is widely used in the pharmaceutical and food industries. During purification, the lactose syrup must be clarified after treatment with lime and activated carbon. DrM filters are ideal for this polishing step, offering closed-system operation, optional cake washing, and dry discharge of filter aid residues. With no need for precoating and high filtration rates, they support consistent production of pharmaceutical-grade lactose while minimizing product loss and waste.​

Filtration plays a critical role in refining sugar and producing high-purity sweeteners such as glucose, fructose, or stevia extracts. FUNDABAC® filters are used in polishing steps to remove insoluble particles, decolorizing agents, and impurities after ion exchange or activated carbon treatment. Their closed, hygienic design supports food-grade compliance, while the ability to discharge as slurry or dry cake helps adapt to different process setups. The system’s scalability and consistent performance make it suitable for both standard and specialty sweetener production.​

In vegetable oil refining, filtration is used to remove bleaching earth, catalysts, and fine impurities after hardening, degumming, neutralization or winterization. Filtration systems are commonly used in hydrogenation stages to separate solid catalysts and provide cleaner oil for downstream steps. The filter’s enclosed design improves safety, reduces fire risk, and supports recovery of expensive catalysts. With automatic operation, backflush options, and flexible discharge modes, FUNDABAC® systems help streamline operations in edible oil processing and specialty fat production.​
