What red flags indicate steam temperature inconsistencies in your plant?
Being responsible for processes and production in a brewery will often mean you spend your valuable time resolving operational issues. However, effective problem solving depends on knowing where to look for anomalies, inefficiencies or mistakes - however hidden they may be.
Consider this, is it possible that you might overlook certain areas as potential causes for production issues?
The precise control of the steam that is heating your process could be one of those hidden impacts.
Below are some ‘red flags’ that could indicate you have an issue with steam temperature control:
• Your process takes a long time to warm up
• You may find that you have to clean more regularly or use an increased amount of cleaning chemicals
• You have taste/taint/colour issues with your product
Are you experiencing these problems? Perhaps you have tried different avenues to resolve them without being entirely successful?
If so, you should take a closer look at your steam temperature controls. The increase in the temperature of the steam that is heating the wort in your kettle should be precisely controlled.
A requirement of most recipes is that the steam temperature should be ‘tracked’ by the temperature of the wort itself.
In other words, the steam temperature should gradually increase at a similar rate to the raising temperature of your wort. This relationship must be carefully maintained to control the Maillard reaction and caramelisation taking place.
Exposing the wort to a consistent heat will help to maintain flavour and overall product quality
Negative and unwanted consequences of exposing the wort to excessive heat are an inconsistency in flavour, browning, taste, taint and ultimately quality. In the worst cases it will affect product quality to the point of entirely spoiled batches.
Excessive or uncontrolled heat can also exacerbate fouling on the heat exchanger surfaces. Build-up of product burn-on has a negative effect on heat transfer efficiency, which in turn will affect your operational effectiveness. Poor heat transfer efficiency means your process will take a longer period to warm up, essentially prolonging production. And if you must clean your equipment more regularly because of the increased formation of burn-on during your batches, this again will cause production delays.
All these effects can be avoided by ensuring the steam temperature is precisely controlled in line with the raising temperature of your wort. The installation of effective steam controls and instrumentation on your process is key and Spirax Sarco can help.
We can provide:
- Controls and instrumentation to suit your requirements
- Consultation around requirements
- Advice to on the best solutions to integrate with existing infrastructure or new infrastructure

You may feel that your boilerhouse just needs to keep doing its job, and as long as it continues to pump out the steam your process needs, you don’t need to worry about it – right?
Recovering lost energy and water from your steam processes allows you to reuse it for other processes. Spirax Sarco will show you how.
I’m a true believer in the idea that you learn something new every day. From discovering the meaning of a word you’ve never heard before to mastering a new culinary skill in the kitchen, learning makes life interesting and it also helps you develop as a person too.

There are two ways to lose steam from a process: controllable flash steam losses such as leaking safety valves, the other is unavoidable loss, known as flash steam.
