Product Specifications

Technical details and manufacturing context for Proportioning Dosing Unit

Definition

Within an Automated Beverage Blending and Carbonation System, the Proportioning Dosing Unit is a critical subsystem responsible for the precise volumetric or gravimetric measurement and controlled release of liquid or syrup ingredients. It ensures consistent recipe formulation by delivering exact proportions of each component to the mixing chamber, directly impacting the final product's flavor, sweetness, and quality. The unit typically operates using positive displacement pumps (e.g., piston, diaphragm, or peristaltic) or precision metering valves controlled by a programmable logic controller (PLC). It receives recipe instructions, activates the appropriate pump or valve for a calibrated duration or number of strokes, and transfers the exact volume of ingredient from a supply tank to the main blend stream. Constructed with food-grade materials such as AISI 316L stainless steel, food-grade elastomers, ceramic, and PTFE, the unit is designed for hygienic processing and corrosion resistance. Key parameters include a rated capacity of 500–2000 L/h, dosing accuracy of ±0.5%, repeatability of ±0.2%, operating pressure of 1.0–1.6 MPa, operating temperature of 4–85°C, and a 24 V DC power supply (±10%). It handles ingredient viscosities from 1–1000 mPa·s, temperatures from 4–85°C, particle sizes up to 0.5 mm, and pH levels from 2 to 12. The wetted materials are 316L/EPDM (ASTM A240), and ingress protection ranges from IP54 to IP65 (IEC 60529). The unit weighs 80–150 kg and has dimensions of 800×600×1200 mm (L×W×H). These specifications serve as reference ranges; actual values must be confirmed with the manufacturer for specific applications. The unit is a component, not a standalone system, and requires integration with a control system and supply tanks. Verification of model-specific parameters and standards is essential before procurement.

Working Principle

The Proportioning Dosing Unit operates via positive displacement pumps or precision metering valves controlled by a PLC. The PLC receives recipe instructions and activates the appropriate pump or valve for a calibrated duration or number of strokes, ensuring exact ingredient volumes are transferred from supply tanks to the mixing chamber. This method provides high accuracy and repeatability, critical for consistent product quality.

Components / BOM

Dosing Pump Head
Creates the positive displacement action to move a precise volume of fluid. Types include piston, diaphragm, or peristaltic.

Material: Stainless Steel, Ceramic, PTFE
Actuator (Motor/Solenoid)
Provides the mechanical force to drive the pump mechanism or open/close metering valves based on control signals.

Material: Steel, Copper, Aluminum
Control Valve
Precisely starts and stops the flow of ingredient to/from the pump chamber or directly into the main line.

Material: Stainless Steel, PTFE Seals
Inlet/Outlet Manifold
Distributes fluid from the supply tank to the pump and from the pump to the discharge point. Often includes check valves.

Material: Stainless Steel
PLC Controller
Takes the recipe and fires each pump or valve for the calibrated stroke count.

Frequently Asked Questions

What is the typical dosing accuracy of this unit?

The reference accuracy is ±0.5%, with repeatability of ±0.2%. However, actual performance depends on the specific model, ingredient properties, and installation conditions. Always verify with the manufacturer.

Can this unit handle high-viscosity ingredients?

The specified viscosity range is 1–1000 mPa·s. For higher viscosities, pump adjustments may be required. Confirm suitability with the manufacturer for your specific ingredient.

What are the electrical requirements?

The unit requires a 24 V DC power supply with a tolerance of ±10%. Ensure stable voltage to maintain consistent dosing accuracy.

Is the unit suitable for washdown environments?

The ingress protection rating is IP54 to IP65, depending on configuration. IP65 is suitable for washdown environments, but verify the specific model's rating.
