Brewing has always been considered a complex process that requires highly skilled personnel. Special attention is required for separation processes in order to separate different properties of beer and create a refreshing brew.
Centrifuges fulfill the requirements of breweries by optimizing the entire production process, maximizing output while ensuring the highest quality.
Application of Centrifuges in Craft Beer
Centrifuges are used in craft beer production for pre-filtration, yeast count control (maintaining specific turbidity), and recovery of wort from hot coagulum.
Beer centrifuges are indispensable tools for any brewery.
Before transferring draft beer to a maturation vessel for final conditioning, beer centrifuges remove solids such as yeast and hops.
Centrifugation is an important step in the brewing process as it prevents unwanted particles from entering the final product. It can also be used to remove undesirable elements like bacteria or wild yeast.
Role of Centrifuges in Breweries
The use of centrifuges in breweries offers several advantages, including significant reduction in processing time and increased throughput compared to traditional filtration and sedimentation methods. It enables control of total suspended solids (TTS) in clarified beer and allows direct bottling. Additionally, centrifuges maintain lower inlet and outlet temperatures, minimizing flavor and mouthfeel loss for a longer product shelf life.
Through frequency conversion drive, the service life of centrifuges is increased while costs are reduced. Craft brewers can achieve a quick return on investment.
Precautions for Using Beer Centrifuges
As centrifuges are high-speed rotating machines, the drum generates significant centrifugal force during operation. To ensure the safety of operators and equipment, the following safety rules must be strictly observed:
Thoroughly clean and disinfect before use, and avoid oxygen operation.
After use, ensure proper cleaning to keep the machine clean and orderly.
Regularly check for loose and abnormal parts.
Prohibit overspeed operation to prevent damage to the machine’s service life.
Before starting the machine, check the oil level of the gearbox. The oil level should not be lower than the engraving line in the middle of the sight glass.
Ensure that materials entering the centrifuge will not damage the metal residues or other hard substances inside the drum.
Use soft water with a total hardness (calculated as CaO) of less than 250mg/L, complying with drinking water standards. Pay attention to the control of operating water pressure, which can be adjusted within the range of 0.3-0.6MPa. The required pressure for device adjustment should remain stable.
