Brew 20
The use of separators in different brewery applications goes back to the beginning of the 1900s. Based on the long-term cooperation with the brewery industry, Alfa Laval separators are specially designed for the requirements and demands of this industry. The Brew separators are high performance clarifiers with intermittent solids discharges. The design ensures low power consumption and keeps the oxygen pick-up at a minimum. The Brew separators are offered as complete skids or modularized systems that are easy to install and operate. They are fully equipped with a user-friendly control panel, valves, instruments, and other components for process and utilities control.
Product Description
Application
The Brew 20 specially designed for green beer and beer preclarification or polishing duties with the target to produce the best quality beer with high performance and maximized yield.
Benefits
- High separation efficiency
- Gentle treatment of the product
- Minimized oxygen pick-up
- Complete system handling both process and utility requirements
- Robust and reliable design
Design
The Brew 20 separation system consists of a separator, a process & service liquid unit, and an electrical & control system. All components are skid mounted to facilitate “Plug
and Play” installation, which results in a small footprint. It can be configured from a selection of basic and other optional standardized units and control functions.
It has a clarifier type of bowl with a conventional top-fed design. The liquid outlet is sealed mechanically by an axial hermetic seal that prevents oxidation of the clarified product.
All metallic parts in contact with the process liquid are made of stainless steel. Gaskets and seals in contact with the product are made of FDA approved material and are approved according to food regulations (EC1935/2004). The separation system is designed for completely automated Cleaning in Place (CIP).

Working principle
The process & service liquid unit monitors and regulates the flow and pressure of the feed and utilities liquids in and out of the separator.
The feed enters the separator bowl from the top. Separation takes place between the bowl discs as a result of the centrifugal force that causes the solids to move towards the periphery. The clarified/separated liquid is continuously pumped out of the mechanically sealed bowl by an integrated paring disc through the outlet at the top of the separator.
The solids collected in the periphery of the bowl are discharged intermittently through the discharge ports. The discharge is triggered by a timer or by an optional turbidity
meter mounted on the clarified product outlet pipe. The discharged solids can be pumped out of the system by the optional solids receiving unit.
The process & service liquid unit also controls the separator’s discharge system, flushing, and CIP.
