CIP Cleaning Instructions

1. **CIP Cleaning Instructions**

- **Introduction to CIP**:

- Cleaning in Place (CIP) is a modern, efficient cleaning technology used in industries like dairy, beverage, and pharmaceuticals.

- Key advantages include:

- Simplified, labor-saving operation.

- Thorough cleaning with disinfection and sterilization.

- Reduced workshop space requirements.

- Recycling of cleaning agents for cost-effectiveness.

- Automation and programmability for large, medium, and small equipment.

- **Features of Separate Tank CIP Equipment**:

- Comprises acid, alkali, and clean water tanks for independent cleaning.

- Equipped with a reflux system for liquid recycling and environmental benefits.

- Tank size and control methods are customizable.

- **Working Principle**:

- Cleaning solutions are heated and circulated through storage tanks via centrifugal pumps.

- Cleaning steps are programmed for sequential acid wash, water rinse, and alkali wash, controlled by solenoid valves and timers.

- **Technical Parameters**:

- Tank capacities: 2000 L each for acid, alkali, and clean water.

- Pump performance: 20 m³/h flow, 35 m lift, 4 kW power.

- Operating temperatures: 65–75°C for acid/alkali, 95°C for hot water.

- **Control System**:

- Panel displays liquid temperatures and cleaning times.

- Operators set cleaning durations for each solution and activate processes via the control panel.

- **Installation and Commissioning**:

- Tanks should be aligned on a flat surface with proper drainage.

- Pipes, instruments, and electrical devices must be installed and tested for leaks and functionality.

- **Usage and Maintenance**:

- Clean equipment before use and monitor solution concentrations.

- Drain and clean tanks when not in use.

- Maintain instruments and electrical components per manufacturer guidelines.

- **Application Examples**:

- **Ultra-High Temperature Sterilizers**: Alkali, acid, and hot water cleaning cycles.

- **Material Pipelines**: Ensure turbulent flow for effective cleaning, with proper pipe inclination for drainage.

2. **Scale Removal in Reactors**

- **Pickling Temperature**: Optimal at 60°C to balance descaling and corrosion control.

- **Solution Concentration**: Use 81% formic acid, 17% water, 1.2% buffer, and 0.8% surfactant.

- **Cleaning Steps**:

1. Flush equipment to remove impurities.

2. Perform acid cleaning (2 hours static, 3–4 hours circulation).

3. Conduct alkaline cleaning to neutralize and prevent corrosion.

4. Rinse thoroughly with clean water.

- **Passivation Treatment**: Protect equipment surfaces after cleaning to prevent corrosion.
