Feed Reservoir/Tank: Capacity 100-10,000 liters

Component Specifications

Definition

A feed reservoir or tank is a critical component in industrial feed systems designed to store bulk materials (powders, granules, liquids, or pellets) and provide controlled, consistent discharge to processing equipment. It serves as a buffer between material supply and consumption points, ensuring continuous operation by compensating for variations in material delivery or processing rates. These tanks incorporate features like level sensors, agitation systems, discharge mechanisms, and venting to maintain material integrity and flow characteristics.

Working Principle

The feed reservoir operates on gravity or pressure-driven flow principles. Material enters through an inlet, accumulates in the storage chamber, and exits through a controlled discharge outlet (e.g., valve, screw conveyor, or pump). Level monitoring devices regulate refill cycles, while internal components (like agitators or fluidizers) prevent material bridging, segregation, or compaction to ensure uniform discharge. The tank maintains a head of material to provide consistent pressure for downstream feeding.

Materials

Typically constructed from carbon steel (ASTM A36), stainless steel (304/316L for corrosion resistance), aluminum, or food-grade plastics (HDPE, PP). Interior surfaces may have coatings (epoxy, Teflon) or polishing for specific applications. Seals and gaskets are often made from FDA-approved elastomers (EPDM, silicone) or PTFE.

Frequently Asked Questions

What is the difference between a feed reservoir and a silo?

A feed reservoir is typically smaller (under 10,000 liters) and integrated directly into a machine feed system for short-term buffering, while a silo is a large standalone storage structure for long-term bulk material holding.

How do you prevent material clogging in a feed tank?

Use internal agitators, fluidizing systems, or vibrators; ensure proper hopper angles (≥60°); and select appropriate surface finishes to reduce material adhesion.

What maintenance is required for feed reservoirs?

Regular inspection of seals, level sensors, and discharge mechanisms; cleaning to prevent cross-contamination; and checking for corrosion or wear in material-contact surfaces.
