The LEWA ecodos sanitary/hygienic diaphragm metering pump’s combination of reliability and metering precision makes it ideal for injecting flavouring agents during beer production.
One of the most important aspects of beverage production is ensuring consistency in both taste and quality.
Nowhere is this more important than in beer production.
Flavouring agents are often used to achieve uniformity. These can be of three types: natural flavours obtained by physical, microbiological or enzymatic processes, nature-identical flavouring substance obtained by synthesis or isolated through chemical processes or artificial flavourings typically produced by fractional distillation and chemical manipulation of naturally sourced chemicals.
These agents have to be added at exactly the right time and exactly the right quantities, which can represent something of a challenge.
This is why LEWA pumps have proved so suitable.
LEWA ecodos sanitary/hygienic diaphragm metering pumps are ideal for this challenging task because of their high reliability and metering precision.
They are suitable for metering and pumping tasks in the low-pressure range, with a flow rate of 0.4 to 1500 l/h per pump head and a maximum discharge pressure of 20 bar.
The LEWA ecodos sanitary/hygienic pump heads (made of polypropylene or stainless steel) are hermetically sealed which prevents the pumped product from becoming contaminated.
They have virtually no dead spaces and are easy to clean with surfaces adapted specifically for hygienic production. This makes them a safe, efficient option for food and pharmaceutical production.
The flow rate of the pump is continuously adjusted with an electromagnetic flow meter and control loop to keep the proportion with the beer flow rate.
This is all fully PLC-controlled, but the system can also work ‘manually’, in which case the flow rate is adjusted by a potentiometer. On the discharge side a contactor protects the pump from overpressure.
