The brewing process relies on the correct addition of yeast and other additives to produce a consistent, quality beer. Sine Pump sanitary positive displacement (PD) pumps offer accurate and gentle yeast dosing. Low pulsation maintains product stability. Other applications include the handling of finings without damage, low-shear transfer of wort, and yeast cropping, a process that takes advantage of Sine Pump’s ability to handle highly viscous products.
- Process Overview
At a very basic level, all beer is made the same way. There are four main ingredients: water, malted barley, hops and yeast. And while the process may be simple, the execution is highly sophisticated. The major steps of brewing are outlined below:
- Milling: Malted barley must first be ground to expose the starches inside the kernel.
- Mashing: The milled barley is mixed with hot water, which the brewing process refers to as “liquor,” in a vat called a “mash tun.” Natural enzymes in the barley convert the starches to sugar. After mashing, the liquid, now known as “wort” is pumped to the brew kettle.
- Boiling: As the kettle boils, hops are added to the wort to provide flavor, aroma and bitterness to the brew. At the end of the boil, the hopped wort is clarified and cooled.
- Fermentation/Conditioning: The wort is then pumped to a fermentation vat where yeast is added or “pitched.” The yeast converts sugars into alcohol and carbon dioxide. After fermenting, the beer is allowed to condition. During this stage, pumps draw settled yeast from the bottom of the vessel, a process known as “yeast cropping.”
- Clearing: Excess yeast is cleared out of the beer through filtration or “fining.” Fining is the process of adding reactive substances to the cloudy beer to produce a bright, clear appearance.
- Typical Applications
- Sine Pump can be used for the dosing of yeast, finings and other additives.
- Sine Pump can be used to transfer wort from the mash tun to the brew kettle, and from the brew kettle to the fermentation vat.
- Sine Pump can be used for yeast cropping, a process whereby yeast that has settled after fermentation is racked off the beer.
- Sine Pump Advantages
- Patented single rotor design provides low shear and constant, pulsation-free flow for superior handling of yeast, wort and additives without damage.
- True positive displacement provides accurate yeast and finings dosing for consistent beer taste and quality.
- Powerful suction capability can handle varying yeast viscosity in the yeast cropping process.
- Sine Pump can run dry for short periods without contaminating the beer.
- Simple construction offers easy and lower cost in-plant maintenance, keeping the brewing process up and running.
