The Alfa Laval Yeast Cooler is a pre-assembled module that offers breweries a compact, easily retrofittable unit that provides the gentle and rapid cooling that is essential to making top quality beers. The yeast cooling system is fully compliant with food industry regulations. This means that all components of the system in contact with process liquids are made of stainless steel with heat resistant seals.
Reliable yeast cooling in compact format
- Compact and sanitary design keeps footprint to a minimum
- Quick and easy to maintain thanks to the yeast cooling system’s plate heat exchanger with easy-service Clip-On gaskets
- A sanitary flow switch stops the cooling process immediately if the yeast flow stops to prevent freezing and prolong uptime
- Comes pre-assembled on a skid and is factory tested before delivery
- Designed for CIP and sterilization for easy and seamless operation and reduced downtime
Yeast cooling process
The yeast is cooled in counter-current by a circulating coolant. An internal coolant recirculation pump is included when required by the application. This helps ensure the smallest possible temperature difference between coolant and yeast at all times.
Any stoppage in the yeast flow is detected by a sanitary flow switch, and the cooling is stopped immediately.
The Yeast Cooler is supplied with a PID controller to control the cooling operation. As an option, it can be supplied with a PLC. Relevant process data displayed includes yeast temperature and yeast flow (when a flow transmitter has been included in the scope of supply).
