Solutions · Gelatin Storage
Gelatin and collagen are high-value, hygroscopic ingredients for confectionery, dairy, desserts, and nutrition. PW Silo Systems reviews your gelatin product with you and designs aluminum and stainless steel silos with the right discharge and hygienic design.
Gelatin Storage at a Glance
A gelatin silo stores gelatin granules or powder, collagen peptides, or other gelling agents close to production – for gummies, confectionery, dairy, desserts, or nutrition products. It protects the product from moisture and contamination and feeds it in a controlled way to dosing and mixing.
Gelatin binds water and fine collagen powders tend to cake. Because gelatin products are not yet on our tested list, we review your product data with you before we design the silo.
Why Gelatin Is Demanding
Gelatin and collagen are sensitive, high-value ingredients. Their quality depends on how they are stored.
Gelatin binds water – it absorbs moisture from the air and forms lumps.
Collagen peptides and fine gelatin powders are cohesive and tend to bridge.
Confectionery, dairy, and nutrition plants work to high hygiene standards.
In coated carbon steel silos, flaking paint and steel particles can end up in the gelatin.
Fine gelatin dust is combustible. Filling and conveying release dust into the silo and its surroundings.
Food plants often handle several gelatin products 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 gelatin silo depends on your product, your process, your cleaning requirements, and your site – we review it with you.
Your Gelatin 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.

FAQ
Answers to the questions plant managers, engineers, and buyers ask most often about storing gelatin in silos.
Dry gelatin granules and powders can generally be stored in a properly designed silo. Gelatin products are not on our tested list yet – we review these products with you based on your material data:
Related hydrocolloids such as agar and carrageenan are on our tested list.
Gelatin binds water. A closed silo in aluminum or stainless steel protects it from outside moisture, and discharge aids such as PW SpeedBlow and bin activators keep the outlet clear.
Both. Aluminum and stainless steel silos are widely used for gelatin 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 gelatin. That is why we build silos exclusively in aluminum and stainless steel.
In mass flow, the entire silo content moves downward when material is discharged – not just a channel in the center. Your gelatin 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 gelatin 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.
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.
