CIP Guide for Craft Breweries

CIP Guide for Craft Breweries

In craft breweries, CIP is a vital process that maintains high standards of cleanliness and hygiene, ensuring the quality and safety of the beer produced. Pipes and tanks in brewery equipment are not easy to clean manually, which means that bacteria can remain even after the equipment is cleaned. To prevent this from happening, high-quality brewery equipment with CIP technology is essential.

What is the CIP system for craft breweries?

The CIP system for craft breweries is an automated cleaning technology designed to clean equipment inside breweries without disassembling it. It removes dirt, residues, and microorganisms by circulating cleaning liquid inside the equipment. CIP systems typically include control panels, pumps, heaters, sensors, and pipe networks. The system automatically performs pre-rinsing, alkaline cleaning, acid cleaning, final rinsing, and disinfection steps according to preset programs to ensure thorough cleaning and sanitation of the equipment and safeguard the quality and safety of craft beer.

The purpose of breweries using CIP systems is to make it easier to maintain hygiene and cleanliness levels. CIP systems reduce the time required for cleaning by reducing the necessary manual labor. This allows workers to focus on other tasks within the facility. CIP systems can also reduce human errors by ensuring that the cleaning agent is appropriate and that any part of the equipment is maintained.

Basic components of CIP systems:

  • Control system: responsible for program control and monitoring of the CIP process to ensure that each cleaning step is carried out according to the preset time, temperature, and flow rate.
  • Pump: used to circulate cleaning liquid and disinfectant, and deliver the cleaning agent to the inside of the equipment through the pipe system.
  • Heater: Heats cleaning liquids (such as water and detergents) to achieve effective cleaning and disinfection temperatures.
  • Pipes and valves: Connect the CIP system to the equipment to be cleaned and control the flow direction and flow of the cleaning liquid.
  • Sensors: Monitor system parameters such as temperature, flow, and liquid level to ensure that the cleaning process meets preset standards.

How CIP Works

CIP systems vary by industry and facility, but they generally follow the same steps. In a brewing facility, the CIP process begins with an initial rinse with clean water to remove any loose debris and yeast residue. Then, an alkaline wash is pushed through the CIP pump to remove any residue and bacteria. After the alkaline wash, it is rinsed with clean water to remove chemicals.

Then, an acid wash cycle is performed, replacing the alkaline cleaner with an acidic cleaner (such as sulfuric acid or phosphoric acid solution) and circulating it through the equipment. Acidic cleaners dissolve mineral deposits and break them off the surface of the equipment. Acid washes are usually performed at temperatures between 60°C and 70°C to enhance cleaning effectiveness. The equipment is then rinsed with a large amount of clean water to ensure that all detergent residues are thoroughly rinsed away.

Finally, the last step is to sanitize the equipment with hot water and a final rinse with a sanitizer. A systematic cleaning and sanitizing process helps maintain the sanitation standards of the equipment and reduces the risk of cross-contamination. A CIP cycle in a brewery can take 60 to 90 minutes. The whole process is automatic. Its automation and efficiency make it an indispensable tool in modern beer production, which not only improves production efficiency but also ensures product quality and safety.

How CIP Works

Main craft brewery equipment for CIP cleaning

  • Fermentation Tanks: Fermentation tanks need to maintain a high degree of hygiene to prevent contamination by bacteria and wild yeast, which may affect the flavor and quality of beer.
  • Filters: Filters are used to remove suspended matter and solid matter from beer. Regular cleaning can ensure their filtration effect and extend their service life.
  • Piping Systems: Piping systems in beer production are responsible for transporting raw materials and finished products. They must be kept clean to prevent cross-contamination.
  • Pumps: Pumps are used to move beer liquid. Regular cleaning can ensure their normal operation and avoid liquid contamination.
  • Bottling Lines: Bottling lines involve washing, filling, and packaging of bottles. Keeping them clean is a key step to ensure the hygiene of the final product.

Benefits of CIP Cleaning in Craft Breweries

  1. Consistency and Precision: Automated CIP systems ensure consistency and precision in the cleaning process. Equipment follows predefined and standardized cleaning protocols every time, reducing the possibility of human error and ensuring adherence to CIP best practices.
  2. Precise Chemical Dispensing: Automated systems can accurately measure and dispense cleaning chemicals according to specified concentrations, ensuring the correct chemical balance for effective cleaning. This helps maintain the optimal chemical-to-water ratio required for thorough cleaning.
  3. Timed and Controlled Cleaning Cycles: Automated CIP systems can precisely control the timing and duration of each cleaning cycle. This ensures that the cleaning solution remains in contact with the surface for the recommended time, maximizing its effectiveness in removing residues.
  4. Real-time Monitoring and Adjustment: Automated CIP systems are often equipped with sensors and monitoring capabilities that track parameters such as temperature, flow rate, and pressure in real-time. Any deviation from set parameters triggers automatic adjustments, ensuring that the cleaning process remains at an optimal level.
  5. Efficiency and Time Savings: Automation reduces overall cleaning time by streamlining processes and minimizing human intervention. This efficiency can reduce downtime between brewing cycles, thereby optimizing the overall production of the brewery.
  6. Save water and chemicals: Automated CIP systems can optimize the use of water and cleaning chemicals by controlling the amount used based on specific cleaning requirements. This not only reduces resource waste but also complies with sustainable and cost-effective practices.
  7. Historical data analysis: Automated CIP systems can record and store historical data of cleaning cycles. This data can be analyzed to identify trends, detect potential problems, and fine-tune the cleaning process, allowing for continuous improvement and increased efficiency.
  8. Remote monitoring and troubleshooting: Some automated CIP systems offer remote monitoring capabilities, allowing brewery operators to oversee and manage the cleaning process from a central location. If problems or anomalies arise, adjustments or troubleshooting can be initiated remotely, minimizing disruptions and ensuring that the CIP process remains on track.
  9. Compliance and documentation: Automation helps to accurately and automatically record each cleaning cycle, ensuring compliance with regulations and quality standards. Detailed records can be easily accessed and presented during inspections or audits.
  10. Enhanced safety: Automation can reduce the exposure of brewery workers to potentially hazardous chemicals and high-temperature cleaning environments. This helps create a safer working environment and minimizes the risk of accidents.

Why is CIP an essential piece of equipment for craft breweries?

  • Ensure hygiene and quality: Craft beer has extremely high requirements for hygiene standards. The CIP system can effectively remove residues and microorganisms in the equipment, prevent contamination, and ensure the consistent flavor and quality of each batch of beer.
  • Improve production efficiency: The CIP system has a high degree of automation and can quickly complete the cleaning work, reducing the time and labor intensity of manual cleaning, thereby improving the overall efficiency and output of the production line.
  • Reduce cross-contamination: During the production of craft beer, there is a high risk of cross-contamination between various equipment and pipelines. Through a systematic cleaning process, the CIP system can effectively reduce the risk of contamination between different batches and types, ensuring that the purity and flavor of beer are not affected.
  • Save costs: Although the initial investment is large, the CIP system can save the labor, time, and chemical costs required for cleaning. In the long run, it reduces equipment failures and downtime and improves the economic efficiency of production.
  • Extend equipment life: Regular and thorough cleaning can effectively reduce the wear and corrosion of beer brewing equipment, extend the service life of equipment, and reduce maintenance and replacement costs.
