How To Solve Pressure Issues In Beer Manufacturing



How To Solve Pressure Issues In Beer Manufacturing

Manufacturing beer at any scale requires strict control over various factors such as temperature, ingredients, and pressure. Of all these factors, pressure is often the most overlooked and yet crucial aspect of beer brewing. While some claim that pressure relief or beer spunding valves are the ultimate solutions, there is much more to solving pressure issues in beer manufacturing.

What Causes Pressure In Beer Manufacturing?

The fermentation process in beer manufacturing produces carbon dioxide as a byproduct, which creates pressure in the brewing vessel. As the fermentation process continues, the pressure inside the vessel increases. This pressure buildup can cause serious problems, such as exploding barrels or tanks if left unchecked.

But pressure is a two-way street when it comes to beer manufacturing. Too much pressure can be disastrous, but too little pressure can also affect the overall quality of the beer. Low pressure during fermentation can lead to slow or incomplete fermentation, resulting in flat or undercarbonated beer.

Identifying Pressure Issues In Beer Manufacturing

A temperature change is one of the first signs of pressure issues in beer manufacturing. If the fermentation vessel or surrounding area becomes warmer than usual, it could indicate increased pressure. Similarly, a drop in temperature can also signify low-pressure levels.

Another tell-tale sign is frequent clogging of pipes or valves. This occurs when there is excessive foaming due to high pressure. As the foam subsides, it can leave behind a thick layer of sediment or debris, which can clog the pipes.

Taste will be a great indicator of pressure issues, too. Under or over-carbonated beer will have a noticeable difference in taste and mouthfeel. Flat beer can taste dull and lack a well-crafted brew’s signature crispness and effervescence. On the other hand, over-carbonated beer can have an overpowering carbonic bite that masks the flavors of the ingredients.

Solving Pressure Issues

Change the valves.

Upgrading to a tri-clamp spunding valve or installing pressure relief valves can help control pressure levels during fermentation. Beer spunding valves allow carbon dioxide to escape once a specific pressure is reached, preventing excessive buildup and the risk of explosions. Pressure relief valves work similarly but are designed for larger industrial brewing systems.

Monitor temperature closely.

Monitoring and controlling the temperature in the fermentation vessel to avoid pressure issues starts with using the right equipment. A temperature-controlled fermenter can help regulate the fermentation process, preventing fluctuations in pressure levels.

Ensure equipment functionality.

Apart from using the right equipment, it is also essential to regularly inspect and maintain all equipment involved in the beer manufacturing process. This includes checking for leaks or malfunctions in valves, pipes, and tanks. A faulty valve or leaky pipe can lead to inaccurate pressure readings and cause potential issues.

Make The Best Beer Possible

Pressure issues don’t have to get in the way of making the best beer possible. By understanding the causes and signs of pressure issues and implementing proper control measures like a tri-clamp spending valve,  temperature monitoring, and equipment maintenance, beer manufacturers can ensure high-quality products consumers will love.
