3A Sanitary Flow Meters in Beer Manufacturing

3A Sanitary Flow Meters have been widely used in multiple industries, meeting the market demand for efficient and sanitary flow measurement solutions. For example, it is necessary to avoid bacterial growth, facilitate frequent cleaning, and withstand high temperature conditions. The specific requirements for disinfection of corrosive alkaline water and hydrogen peroxide are as follows:

• All materials of parts in contact with media meet the requirements of food hygiene, such as the requirements of FDA (U.S. Food and Drug Administration) and EHEDG (European Hygienic Equipment Design Group);

• Parts in contact with the medium can withstand the temperature shock and corrosion caused by steam, alkaline water and hydrogen peroxide cleaning;

• When used in filling process, it should have fast response performance and high measurement accuracy;

• It can adapt to low temperature (about 2℃) and humid working environment. Among many liquid flow meter products, electromagnetic flowmeter can meet the above requirements.

Use of 3A Sanitary Flow Meters in Beer Production Process

Raw material preparation: The main measurement parameters in the raw material preparation process of beer production are weight and level. There are no important flow measurement points, so they are not discussed here.

Wort production: Wort is an important intermediate raw material in beer production, and its measurement is extremely important for the handover and settlement between the previous and subsequent processes (workshops). Wort has a certain viscosity but there is no difficulty in measuring 3A Sanitary Flow Meters. What needs to be considered is the disinfection in the process. The flowmeter used at this measuring point can consider using an electromagnetic flowmeter with a PFA lining (or PTFE) and stainless steel electrodes. It can prevent corrosion from dilute hydrogen peroxide and alkaline water. 

Fermentation: After fermentation and filtration, the sake will be transported to the next process - packaging through pipelines.

High-concentration dilution: Some beers are produced by blending high-concentration original wine. This requires strictly controlling the ratio of high-concentration original wine and sterile carbonated water to ensure the beer degree after mixing.In each production line, two electromagnetic flowmeters are required for proportioning flow control. 

The fluid flow rate is above 1m/s, which makes the flow measurement within the best working range of the instrument. At the same time, the time constant of the flow meter should also be set smaller, generally between 1 and 3s, to improve the sensitivity of the control and ensure the accuracy of the ratio.

Filling: Filling is the last step in beer production, which requires accurate control (±10mL) of the filling volume of each bottle (can, barrel).The sanitary electromagnetic flowmeter has high accuracy and fast response performance and can quickly and accurately control the filling volume of each bottle of beer.Usually, this type of electromagnetic flowmeter has a smaller diameter, generally between DN2.5 and DN40, with a compact size and a response speed of 0.3s.

Some Application Considerations

Impact and treatment of operating process

Due to product hygiene requirements, the food industry needs to regularly disinfect process pipelines (including flow meters) with disinfecting media. The media used include hot water (above 85°C), steam, alkaline water (above 50°C) and hydrogen peroxide.In this regard, we need to pay attention to the above-mentioned disinfection process with a relatively high temperature medium. This is dangerous for 3A Sanitary Flow Meters with linings. If the operation is not careful, the instrument may be easily damaged.

From the perspective of corrosion resistance, temperature resistance and hygiene, 3A Sanitary Flow Meters uses PFA as the lining material, which is accepted by the majority of users in the food industry and can meet many demanding operating requirements.Effect and treatment of bubbles in the medium

Prevent insulation degradation caused by condensation

During the beer production process, the medium is at a relatively low temperature most of the time. For example, when beer is being filled, its temperature is often lower than room temperature, at around 2°C. At this time, condensation water is easily generated at the part of the process pipeline that comes into contact with the air.

At this time, the correct method should be to choose 3A Sanitary Flow Meters with clamp connection, split type, and IP67 or IP68 protection level. Since the sensor of this protection level is completely sealed, no matter how harsh the environment is, there will be no worries about condensation water in the electromagnetic flow meter.
