Almond flour sits at the heart of countless food products from bakery goods and confectionery to snack coatings and plant-based formulations. However, milling alone does not produce a perfectly uniform powder. Often, coarse fragments and oversized particles are carried through to the end product. Removing them early in the process protects product quality, safeguards customer satisfaction, and keeps production running without interruption.
Why does almond flour cause mesh blinding and screening downtime?
Unlike dry and free-flowing powders, almond flour behaves differently on a screen. Its natural oil content causes particles to stick together and block the mesh apertures. Over time, these blocked apertures reduce the effective screening area and lower productivity. Addressing mesh blinding at the source helps manufacturers reduce unplanned downtime and operator involvement.
Why is contamination a key risk when screening oily food powders?
Oily food powders like almond flour create two distinct risks during screening. First, product residue builds up on equipment contact surfaces, leading to cross-contamination and allergen carry-over between production runs. Second, the oily product blocks mesh apertures, reducing the effective screening area. With fewer open mesh pores available, material moves across the surface without being fully separated. This allows oversized contaminations to reach the finished product undetected.
Together, these issues can result in inconsistent product quality and potential product recalls. Hence, selecting the right screening equipment helps to manage these risks effectively with maximized productivity.
What should manufacturers consider when selecting sieving equipment for food-grade almond flour?
Screening a food-grade product like almond flour requires equipment that delivers both effective separation and strict hygiene control. Our Finex Separator™ is built with food-grade contact parts and is available with FDA-compliant adhesive as a standard option, helping manufacturers meet food safety requirements with confidence. Its design allows fast disassembly and cleaning, supporting quick turnaround between product changeovers, particularly valuable for facilities processing multiple nut-based products on the same line. This unit integrates directly into existing production layout without structural modifications, making it straightforward to add reliable screening without having to redesign the line.
Our Finex Separator™ in action
In this demonstration, our Finex Separator™ is set up in a 48-inch, double-deck configuration fitted with deblinding discs to screen almond flour at high capacity.
As material feeds across the screening surface, the deblinding discs apply continuous vibratory forces to the mesh, preventing the oily almond flour from blocking the mesh apertures. The discs also break down oversized agglomerates into fine powder, allowing them to pass through the mesh and maximize product yield. The contaminants are retained on the screen surface and directed to a separate collection bin. The result is smooth, consistent almond flour ready for further processing or packaging with no manual intervention required during the run.
This unit is a high-capacity vibratory separator built for demanding food processing applications, enabling manufacturers to achieve a consistent screening rate without the gradual performance drop, unlike conventional setups. Its robust construction, flexible configuration, and crevice-free design enable easy cleaning and rapid access to all contact surfaces, minimizing downtime between production runs.

Frequently asked questions:
Almond flour often clogs the mesh apertures. Will the Finex Separator™ have the same challenge?
Mesh blinding is the single biggest challenge with oily nut flours. Our Finex Separator™, paired with the Russell Vibrasonic® Deblinding System, is particularly designed to prevent these blinding issues. The deblinding discs continuously clear the mesh, keeping apertures clean and maintaining stable productivity.
We need to remove particles above a specific size from our product. Can the mesh be tailored to our specifications?
Yes. The mesh micron size is selected based on your target particle size. Our engineers will recommend the right setup once they understand your product and specification requirements. If you are unsure, a trial at our test centre or an in-house test at your facility can be arranged to confirm what works best.
How does the Finex Separator™ cope with the variability we see batch to batch in our almond flour?
Almond flour properties vary with the quality of raw material, milling parameters, and seasonal variation. Our Finex Separator™ is configured to handle a range of conditions, and the deblinding system ensures that even stickier or higher-moisture batches do not compromise screening performance.
Where in our production line will the Finex Separator™ be integrated?
Most commonly, the separator is placed immediately after milling as a check screen to eliminate oversized material before it moves to blending, coating, or packaging. It can also be positioned before packaging as a final quality check. The right placement depends on your process, and our team can advise based on your production layout.
We process several nut-based products on the same line. How quickly can we switch over?
Our Finex Ultima™ is designed for fast disassembly and cleaning. Food-grade construction and accessible internals mean changeovers are quick, reducing downtime between product runs and supporting allergen management protocols.
What screening capacity can the Finex Separator™ achieve with almond flour?
Screening capacity varies with the material properties, mesh size, and the percentage of oversized content in the product. Testing with your specific product at our technical centre will provide an accurate capacity figure for your application.
Does the Finex Separator™ handle other food powders beyond almond flour?
Yes. The unit handles a wide variety of food-grade powders and granular materials with ease, including those with oily, sticky, or high moisture properties that tend to challenge conventional screening equipment. Nut flour, spices, and comparable products all fall comfortably within its range of capability.
