Technical details and manufacturing context for Agent Storage Hopper

Definition

The Agent Storage Hopper is a critical component of the Agent Injection System, responsible for the temporary storage, controlled feeding, and precise dispensing of chemical agents, additives, or other materials into the main production or processing stream. It ensures a consistent and reliable supply of the agent to the injection mechanism. The hopper is typically constructed from stainless steel grades 304 or 316L, with material selection depending on the corrosiveness of the agent. It is available in capacities ranging from 50 to 500 liters, with custom sizes possible. The operating pressure range is 1.0 to 1.6 MPa, and the operating temperature range is -20 to 80°C, limited by seal material. The hopper features inlet and outlet diameters of 100–300 mm and 50–150 mm respectively, and a height of 500–1500 mm, with a cylindrical section diameter of 400–1000 mm. The weight varies between 50 and 200 kg, depending on capacity and material. Surface roughness is ≤0.8 μm Ra for hygienic applications, and seal materials are EPDM or FKM, with FKM for higher temperatures. Pressure ratings are PN10/PN16 per EN 1092-1. The hopper operates on gravity or with an integrated feeding mechanism such as a screw feeder or vibratory tray, and includes features to prevent material bridging, ensure flow, and allow for level monitoring or refilling. For selection, verify compatibility with the specific agent, required capacity, and process conditions. Confirm model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The hopper stores a bulk quantity of the agent. Material is fed from the hopper, typically via gravity or an integrated feeding mechanism (like a screw feeder or vibratory tray), into the downstream injection point. It often includes features to prevent material bridging, ensure flow, and allow for level monitoring or refilling.

Components / BOM

Hopper Body
Main containment vessel for the stored agent.

Material: Stainless Steel
Discharge Valve/Gate
Controls the flow of material out of the hopper.

Material: Stainless Steel
Level Sensor
Monitors the fill level of the agent within the hopper.

Material: Sensor-specific (e.g., plastic, stainless steel housing)
Bridging Prevention Device Optional
Breaks arches over the outlet so the agent keeps flowing — a vibrator, fluidising pad or agitator.
Integrated Feeder Optional
Meters the agent out instead of letting it fall by gravity, on hoppers with a built-in feeder.

Frequently Asked Questions

What materials are available for the Agent Storage Hopper?

The hopper is available in stainless steel 304 or 316L, as listed in the directory. The choice depends on the corrosiveness of the agent; 316L is recommended for corrosive agents. Confirm the appropriate grade with the manufacturer.

What is the capacity range of this hopper?

The directory lists a capacity range of 50 to 500 liters, with custom sizes available. The actual capacity should be selected based on the required storage volume and process needs.

What are the operating pressure and temperature limits?

The operating pressure range is 1.0 to 1.6 MPa, and the operating temperature range is -20 to 80°C. The temperature limit is influenced by the seal material; FKM seals are suitable for higher temperatures. Always verify these parameters for your specific application.

How is the hopper fed and how does it dispense the agent?

The hopper can be fed by gravity or via an integrated feeding mechanism such as a screw feeder or vibratory tray. It includes features to prevent material bridging and ensure consistent flow. The dispensing is controlled to provide a reliable supply to the injection point.
