Ingredient Hopper for Chemical Manufacturing

Product Specifications

Technical details and manufacturing context for Ingredient Hopper

Definition

The Ingredient Hopper is a component used in chemical manufacturing and other industrial processing systems to store and dispense raw materials such as powders, granules, and bulk ingredients. It serves as the initial material handling point in production lines, providing controlled discharge to downstream equipment while helping to prevent contamination and maintain material integrity. The hopper is designed for gravity-fed flow, with a conical or pyramidal bottom that directs material toward an outlet. Discharge is controlled via mechanical gates, valves, or vibratory feeders, and the geometry is engineered to minimize bridging or rat-holing. Level sensors monitor material quantity, and optional agitation systems can be added to maintain flow in cohesive substances. Available materials include Stainless Steel 304/316L (per ASTM A240) and food-grade polyethylene. Standard capacity ranges from 0.5 to 5 m³, with custom sizes available. Wall thickness typically ranges from 3 to 6 mm, depending on capacity and material. Operating pressure is rated at 1.0–1.6 MPa, and operating temperature ranges from -20 to 80°C, with higher temperatures requiring special seals. Discharge rate varies from 5 to 50 t/h, depending on material flowability. Hopper angle is typically 45–60°, with steeper angles for cohesive materials. Internal surface finish ranges from 0.4 to 1.6 μm Ra (ISO 1302), with lower values for hygienic applications. Weight ranges from 200 to 2000 kg, and inlet/outlet diameters are 100–300 mm (DIN 11851), with custom flanges available. IP ratings of IP54–IP65 are offered for outdoor or dusty environments. All specifications are reference ranges and must be verified with the supplier for the specific model and application.

Working Principle

The Ingredient Hopper operates on a gravity-fed principle. Stored ingredients descend from the hopper's conical or pyramidal bottom section toward the outlet. Discharge is controlled by mechanical gates, valves, or vibratory feeders at the outlet, which regulate the flow rate. The hopper's geometry is designed to prevent material bridging or rat-holing, ensuring consistent flow. Level sensors monitor the material quantity, and agitation systems may be incorporated to maintain material mobility in cohesive substances. The discharge rate is influenced by the hopper angle, outlet size, and material properties.

Frequently Asked Questions

What materials are available for the Ingredient Hopper?

The hopper is available in Stainless Steel 304/316L (per ASTM A240) or food-grade polyethylene. The choice depends on the material being handled and application requirements. For corrosive materials, 316L is recommended.

What is the capacity range of the Ingredient Hopper?

Standard capacity ranges from 0.5 to 5 m³, with custom sizes available. The actual capacity required depends on the production volume and material characteristics.

What operating pressure and temperature ranges are supported?

The operating pressure is rated at 1.0–1.6 MPa, and the operating temperature range is -20 to 80°C. Higher temperatures may require special seals; verify with the supplier for your specific application.

How is the discharge rate controlled?

Discharge is controlled via mechanical gates, valves, or vibratory feeders at the outlet. The discharge rate depends on material flowability and hopper angle, typically ranging from 5 to 50 t/h. Confirm the required rate with the supplier.
