Solutions · Sweetener Storage
Dextrose, glucose, and polyols such as erythritol, isomalt, and xylitol are fine, often hygroscopic powders and granules. PW Silo Systems designs aluminum and stainless steel silos with mass-flow discharge, discharge aids, and blending – so your sweeteners flow reliably into production.
Sweetener Storage at a Glance
A sweetener silo is a closed storage vessel for sugar substitutes and sweeteners – such as dextrose, glucose, erythritol, isomalt, or xylitol. It protects the product from moisture and outside contamination and feeds it in a controlled way to mixers, scales, or dosing systems.
Many sweeteners absorb moisture and tend to cake, and fine powders can bridge at the outlet. PW Silo Systems designs the silo geometry, wall material, and discharge equipment around your specific sweetener.
Why Sweeteners Are Demanding
Sweeteners are high-value ingredients. Caking, bridging, or contamination quickly affects production uptime and product quality.
Many sweeteners are hygroscopic. Once they absorb moisture, they form lumps or cake in the silo.
Fine powders such as powdered dextrose can compact and form a bridge over the outlet.
In coated carbon steel silos, flaking paint and steel particles can end up in the sweetener.
Fine sweetener dust is combustible. Filling and conveying release dust into the silo and its surroundings.
Deliveries differ, and a silo filled in batches forms horizontal layers of different quality.
Food plants often handle several sweeteners side by side – including allergen-relevant or specialty products.
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 sweetener silo depends on your product, your process, your cleaning requirements, and your site – we review it with you.
Your Sweetener 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 moreSweetener Types
Particle size, moisture sensitivity, and composition change how a sweetener flows. These sweeteners are on our list of bulk materials tested in our lab.
Tested in our lab
Glucose, glucose powder, corn sugar
Glucose powder is used in confectionery, bakery, and beverages. It tends to absorb moisture, so a closed silo and discharge aids are part of the design.
Tested in our lab
Dextrose, dextrose monohydrate
Dextrose is a widely used sugar in food production and fermentation. Mass-flow discharge supports first-in, first-out stock rotation.
Tested in our lab
Sweeteners, sugar substitutes
Sweetener blends and sugar substitutes differ widely in particle size and flow behavior. Silo and discharge are designed for your specific product.
Tested in our lab
Stevia, stevia blends, steviol glycosides
Stevia is on our list of bulk materials tested in our lab. Stevia blends with carrier ingredients we review with you based on your product data.
Tested in our lab
Isomalt, sugar alcohol, polyol
Isomalt is a polyol used in sugar-free confectionery. A closed, corrosion-resistant silo protects it from moisture.
Tested in our lab
Xylitol, birch sugar
Xylitol is a crystalline sugar alcohol for chewing gum, candy, and oral care products. Storage and discharge are matched to its crystal size.
Tested in our lab
Erythritol, sugar alcohol
Erythritol is a popular zero-calorie sweetener for beverages and baked goods. Mass-flow discharge keeps it moving evenly from the silo.

FAQ
Answers to the questions plant managers, engineers, and buyers ask most often about storing sweeteners in silos.
These sweeteners are on our list of bulk materials tested in our lab:
Stevia blends, sorbitol, maltitol, mannitol, allulose, fructose, polydextrose, and sucralose blends are not on our tested list yet. We review them with you based on your material data.
Both. Aluminum and stainless steel silos are widely used for sweetener 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 sweetener. That is why we build silos exclusively in aluminum and stainless steel.
Many sweeteners – especially glucose, dextrose, and some polyols – absorb moisture from the air. When particles bond, lumps form and discharge becomes uneven. A closed silo in aluminum or stainless steel protects the product, and bin activators or PW SpeedBlow fluidization keep it flowing at the outlet.
In mass flow, the entire silo content moves downward when material is discharged – not just a channel in the center. Your sweetener 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.
Fine sweetener dust is combustible, and many bulk solids carry an explosion risk. For combustible bulk solids we supply explosion-protected silos designed in accordance with applicable codes and regulations. Venting devices – rupture discs or explosion vents – are selected for your silo, your product, and your application. Integrated filters and dust collectors reduce dust during filling and conveying.
Deliveries vary, and a silo filled in batches forms horizontal layers of different quality. PW BlendLine gravity blending silos homogenize the content so your production receives a consistent product. We offer four blending technologies; the right one depends on your sweetener and on whether you operate continuously or in batches.
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.
