500L stainless steel powder container

Product Overview

This 500L stainless steel powder container is specifically designed for use in the food, pharmaceutical, chemical, and health product industries for powdered and granular solid materials. It is suitable for storage, temporary storage, turnover, and quantitative dispensing processes. Made of high-quality stainless steel, it boasts excellent sealing, corrosion resistance, and wear resistance. The smooth, corner-free inner wall prevents powder accumulation, ensuring smooth material flow and safe, hygienic production. The 500L capacity is suitable for small to medium-scale production as well as experimental scale-up or batch formulation needs.

Product Features

Nominal capacity: 500 liters (500L), precisely suited for powder batch management and continuous production.

Material selection: 304 / 316L stainless steel, resistant to corrosion from various powders (containing salt, acid, and alkali components), with no risk of material contamination.

Surface treatment: internal and external mirror polishing or sandblasting, roughness Ra≤0.4μm (customizable), conforming to GMP and food-grade standards, easy to clean.

Structural design

Cylinder: Cylindrical or conical bottom structure, with an optimized cone angle (typically ≥60°) to promote gravity discharge of powder.

Can lid: Quick-opening manhole/feed port, optional with breather filter, breather valve, sight glass, and powder feeding interface.

Discharge: The bottom can be equipped with a butterfly valve, ball valve, rotary valve, or pneumatic flap valve for easy connection to packaging machines or conveying systems.

Optional: Anti-bridging and arch-breaking devices (vibrator, air disc, agitator), weighing modules, level gauges, etc.

Pressure Resistance and Sealing: Designed for normal or slightly negative pressure operation, with silicone/fluororubber sealing rings, dustproof, moisture-proof, and leak-proof.

Typical applications

Food processing: Storage and transportation of raw materials such as flour, powdered sugar, milk powder, starch, seasoning powder, and protein powder.

Pharmaceutical manufacturing: intermediate buffer for traditional Chinese medicine extracts, powders, excipients, raw material powders, and granules.

Chemical industry: Temporary storage of solid materials such as plastic granules, catalysts, pigment powder, titanium dioxide, and additives.

Health supplements and cosmetics: Batch formulation of collagen powder, plant extract powder, talc powder, and foundation raw materials.
