Chemical Dosing Unit for CIP/SIP Systems

Product Specifications

Technical details and manufacturing context for Chemical Dosing Unit

Definition

The Chemical Dosing Unit is a critical component of the Automated CIP/SIP System for Beverage Production. It is responsible for the precise volumetric or gravimetric measurement and controlled injection of various cleaning agents (e.g., caustic, acid) and sanitizers (e.g., peracetic acid, chlorine-based solutions) into the CIP/SIP fluid circuits. Its operation is governed by the system's programmable logic controller (PLC) to ensure repeatable, accurate, and safe chemical delivery according to validated cleaning protocols. The unit typically consists of one or more positive displacement pumps (e.g., diaphragm, peristaltic) or precision metering valves connected to chemical supply tanks. A flow meter or load cell provides feedback for closed-loop control. The system PLC sends a command based on the recipe, activating the pump/valve for a set duration or until a target volume/weight is reached, precisely dosing the chemical into the main CIP flow or a mixing chamber. The unit is available with a range of technical specifications that must be verified for the specific model and application. For example, the flow rate ranges from 0.5 to 10 L/min, with a dosing accuracy of ±0.5%. Operating pressure is 1.0–1.6 MPa, and operating temperature is 5–60 °C. Power supply is 24 V DC (±10%), with optional 230 V AC via converter, and power consumption is 50–150 W. Ingress protection is IP54–IP65 (per IEC 60529). Wetted parts are typically 316L stainless steel (per ASTM A240), with optional PTFE seals for aggressive chemicals. The unit weighs 15–25 kg and has dimensions of 600×400×800 mm (L×W×H). Chemical compatibility covers pH 1–14, with full range options in PTFE and PVDF. The control signal is 4–20 mA (per IEC 60381) for PLC integration. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The unit typically consists of one or more positive displacement pumps (e.g., diaphragm, peristaltic) or precision metering valves connected to chemical supply tanks. A flow meter or load cell provides feedback for closed-loop control. The system PLC sends a command based on the recipe, activating the pump/valve for a set duration or until a target volume/weight is reached, precisely dosing the chemical into the main CIP flow or a mixing chamber.

Components / BOM

Dosing Pump
Provides the motive force to draw chemical from the supply tank and inject it into the process line with precise volumetric control.

Material: 316L Stainless Steel / PTFE / Santoprene
Injection Valve
A solenoid or air-actuated valve that opens to allow chemical injection into the CIP line and closes to prevent cross-contamination or backflow.

Material: 316L Stainless Steel / PTFE
Flow Meter / Load Cell
Measures the actual volume or weight of chemical dosed, providing feedback to the controller for accurate closed-loop operation.

Material: 316L Stainless Steel / Glass (for sight flow indicators)
Chemical Supply Tank
Holds the concentrate the dosing pump draws from.
