This stainless steel mobile material silo (transfer hopper) mainly supports sealed temporary storage and transfer for powders and granules.
In addition, it keeps powders safe and dry, simplifies material transfer, and strongly prevents dust pollution.
Designed for high-hygiene industries, it works perfectly for pharmaceutical and food production, and fully meets the 2010 GMP regulations.
You can choose between two main body shapes to match your process needs.
One option is the square silo, which uses an upper square with rounded corners plus a lower rounded-corner cone.
The other choice is the circular silo, which combines an upper cylinder with a lower cone for smoother flow.
We manufacture the entire unit using high-quality stainless steel 304 or 316L for durability and hygiene.
To avoid material buildup, we design all internal corners with smooth R‑angle arcs that eliminate dead corners.
This special structure allows powders to flow smoothly without residue, simplifies cleaning, and creates an attractive appearance.
We also apply advanced sheet metal processing and precision welding techniques during production.
For interior finish, we polish the inner surface to a 320# mirror finish with roughness Ra ≤ 0.28μm.
As for the exterior, we finish the outer surface with a professional matt sandblasted treatment.
We use a stamping‑formed clamp‑type hopper cover with a quick‑lock system for easy opening.
For reliable sealing, we fit it with a pharmaceutical‑grade white silicone sealing ring.
At the cone bottom, we install a custom large‑diameter quick‑install butterfly valve for reliable discharge.
This valve uses a pharmaceutical‑grade white silicone seal, offers universal compatibility, and disassembles easily for cleaning.
To enhance safety, the operating handle includes automatic positioning and locking to avoid misoperation.
During operation, it delivers sensitive and accurate opening and closing positioning.
For easy movement, we equip the unit with four PU mobile casters, two of which are braked universal wheels.
These wheels protect self‑leveling floors from damage and ensure light, quiet movement.
Thanks to robust construction, the silo body has high structural strength and maintains its shape without deformation.
You can select from multiple movement methods, including hydraulic truck, forklift, or manual operation.
Depending on your needs, we also offer an optional electric or pneumatic flow‑aiding vibrator.
This component breaks powder arches, prevents clogging and wall sticking, and keeps production running continuously.
