Solutions · Lentil Storage
Lentils are small, flat, and free-flowing – and red, brown, green, and black lentils must not be mixed. PW Silo Systems designs aluminum and stainless steel lentil silos with mass-flow discharge and clear product separation.
Lentil Storage at a Glance
A lentil silo stores dried lentils close to production – for packaging, soups, ready meals, lentil flour, or plant-based protein. It protects them from moisture, pests, and contamination and feeds them in a controlled way to the next process step.
Lentils flow well, but split red lentils create fines, and colored varieties must stay separate. PW Silo Systems designs the silo around your lentils and your process.
Why Lentils Are Demanding
Lentil quality and varietal purity depend on how they are stored.
Lentils are a natural product. Moisture and long storage times affect their quality.
In funnel flow, lentils can stay in the silo for a long time while fresh product passes through the center.
In coated carbon steel silos, flaking paint and steel particles can end up in the lentil.
Split lentils create fines and dust during filling and conveying.
Deliveries differ, and a silo filled in batches forms horizontal layers of different quality.
Red, brown, green, and black lentils must not be mixed by accident.
Silo Materials
Aluminum and stainless steel silos are widely used for flour, sugar, starch, and other food ingredients. Both materials offer high corrosion resistance, good hygiene, and a long service life.
Carbon steel is not an option for us: its coating is the only protection against corrosion. Once it wears, paint particles and steel can get into the product. Which of our two materials fits your lentil silo depends on your product, your process, your cleaning requirements, and your site – we review it with you.
Your Lentil Silo System
Silo, discharge, blending, filtration, and safety equipment are engineered as one system. That means fewer interfaces for your team and components that are designed to work together.
Storage
Concentric mass-flow discharge without asymmetric flow zones – as standard, site-assembled, indoor, or multi-compartment silos.
Learn moreBlending
Gravity blending and homogenizing with four technologies, including PW ConeBlend with a hopper that is quick to clean.
Learn moreDischarge
Air fluidization for uniform discharge of poorly flowing products – prevents bridging and can be retrofitted to existing silos.
Learn moreDischarge
Vibration from unbalanced motors breaks up cohesive forces, resolves caking, and keeps the outlet clear.
Learn moreFiltration
Dust separation during filling and conveying, in a hygienic design for the food industry.
Learn moreSafety & Monitoring
Rupture discs or explosion vents for combustible dust, level measurement for reliable monitoring of the silo content.
Learn moreLentil Types
All lentil types below are on our list of bulk materials tested in our lab. For other pulses, we review your material data with you before designing the silo.
Tested in our lab
Red lentils, split red lentils
Red lentils are usually split and cook quickly. Their fines content is considered in the silo and filter design.
Tested in our lab
Brown lentils
Brown lentils are the most common whole lentils. First-in, first-out discharge supports stock rotation.
Tested in our lab
Yellow lentils
Yellow lentils are used in soups and dals. A dedicated silo keeps them apart from red lentils.
Tested in our lab
Black lentils, beluga lentils
Black lentils are small specialty lentils. Separate storage prevents color mixing.
Tested in our lab
Mountain lentils, small green lentils
Small green and brown mountain lentils keep their shape when cooked. Mountain lentils are on our tested list.
Tested in our lab
Plate lentils, large green lentils, Laird lentils
Large, flat lentils for canning and ready meals. Plate lentils are on our tested list – silo and discharge are matched to their shape.

FAQ
Answers to the questions plant managers, engineers, and buyers ask most often about storing lentils in silos.
Dried lentils can be stored in a properly designed silo. These lentils are on our list of bulk materials tested in our lab:
Related pulses such as dried peas and pea protein are on our tested list as well. Other pulses we review with you based on your material data.
Both. Aluminum and stainless steel silos are widely used for lentil and other food ingredients because they offer high corrosion resistance, good hygiene, and a long service life. Which material fits your project depends on your product, your process, your cleaning requirements, and your site. We review the options with you.
In a carbon steel silo, the coating is the only protection against corrosion. If it wears or flakes off, paint particles and steel can end up in your lentil. That is why we build silos exclusively in aluminum and stainless steel.
We recommend a dedicated silo per variety – or PW StoreLine multi-compartment silos that keep several products separate in one silo.
In mass flow, the entire silo content moves downward when material is discharged – not just a channel in the center. Your lentil leaves the silo in the order it came in (first in, first out), and no product is left behind in dead zones where it could age or cake. Our PW StoreLine silos are designed for concentric mass-flow discharge without asymmetric flow zones.
Hygiene starts with the materials: aluminum and stainless steel offer good hygiene and corrosion resistance. In addition, our flat-roof designs support high cleanliness standards, PW SpeedBlow uses high air flow for cleaning, and the PW ConeBlend blending silo has a hopper that is quick and easy to clean – well suited to frequent product changes.
The right size depends on your daily consumption, delivery intervals, the number of products, and the space available at your site. PW StoreLine silos are available in a wide range of sizes and diameters, and silos too large for road transport are assembled on site. We size the system with you – without oversized investment.
Yes. We deliver to every U.S. state and support your project with silo transport, field assembly, silo installation and supervision, and site relocation of existing systems.
Very likely. Our silo systems are designed for nearly all free-flowing, granular, and powdered bulk solids. Send us your material details – kernel size, moisture, and how the product is filled and discharged – and we will review the right storage solution with you.
Tell us about your products, required storage capacity, how the silo is filled and discharged, and your site conditions. Based on this, we work out the material, silo type, and configuration with you and send you a detailed quote.
