Product Specifications

Technical details and manufacturing context for Dosing System

Definition
Dosing systems for the beverage industry are precision components used within syrup preparation units to measure and dispense liquid or powdered ingredients such as sweeteners, flavors, colorants, and active ingredients into beverage recipes. They operate using either gravimetric or volumetric methods. Gravimetric systems employ load cells to measure the weight of the dispensed material, achieving an accuracy of ±0.5% of set point. Volumetric systems use metering pumps, valves, or flow measurement to dispense pre-set volumes, with an accuracy of ±1.0%. The controller receives a target dose from the unit's recipe and automates the process, integrating with the unit's control system.

Key specifications include a throughput range of 10–500 L/min, a dosing volume per cycle of 0.1–100 L, and a viscosity range of 1–10000 cP. Operating temperature ranges from 4–90°C, and operating pressure from 0–6 bar. Wetted parts are constructed from AISI 316L stainless steel, PTFE, EPDM, and ZrO2 ceramic seals, with a surface finish of Ra ≤ 0.8 µm for hygienic design. Connections are DN25–DN100 per ISO 1127. The system is designed for 100% continuous duty with a service life of 10–15 years, requiring utilities such as 230/400 V, 50 Hz, 3-phase electrical supply, compressed air at 6 bar, and water for CIP.

Standards compliance includes ISO 1127, EN 1672-2, FDA 21 CFR 177, and EU 10/2011. When selecting a system, compare dosing accuracy, flow range, dose volume, ingredient viscosity, wetted materials, hygienic surface finish, and CIP compatibility. Maintenance signals include seal wear, which may require replacement every 2–3 years. Failure boundaries include temperatures below 4°C (crystallization of sugars) or above 90°C (seal degradation), pressures above 6 bar (leakage or damage), viscosities above 10000 cP (cavitation), and ambient humidity above 80% RH (condensation on electronics).
Working Principle
The system operates using volumetric or gravimetric methods. A controller receives a target dose from the unit's recipe. For volumetric dosing, pumps or valves dispense a pre-set volume. For gravimetric dosing, load cells measure the weight of the dispensed material until the target weight is reached. The process is automated and integrated with the unit's control system.
