Beer has long been the drink of choice for many Kiwis over the years and this popularity only continues to increase with the rise of craft beer. While popping down to your local shops to pick up a beer or two is simple enough, the process behind producing beer is actually quite complex. Large steel tanks are used nowadays to produce high volumes of beer and high-tech automated systems are used to keep the whole operation ticking along in the background.
These types of systems for beer production can come with an expensive price tag however, recent advancements in technology which include the use of on-site nitrogen generation have seen brewers save impressive amounts of money throughout the brewing process.
Read on to find out more about the beer brewing process, and how nitrogen generation can result in significant cost-savings.
The beer brewing process
There are four stages to brewing beer which are malting, mashing, boiling and fermenting.
- Malting: This first step is where the ingredients of starch, enzymes, protein, vitamins, and minerals are combined together to create the main raw material for the batch of beer.
- Mashing: The second step then involves taking the created malt and mixing it with heated water, where the natural enzymes of the malt break down the starch into sugars. These sugars are then separated from the main mixture to create wort.
- Boiling: After mashing, the wort is then boiled to a controlled temperature which allows the brewer to add additional ingredients specific to the type of beer being produced.
- Fermenting: The final step is where the mixture is cooled and separated. Once divided, the brewer will then add in the yeast that is essential for the fermentation to begin. When the fermentation is finished, the beer is fully matured to deliver the required taste.
Why use nitrogen in the beer brewing process?
Nitrogen is commonly used throughout the beer brewing process. From purging tanks between uses to prevent contamination of the next batch of beer to pushing beer from one tank to another, there are some great practical uses for nitrogen throughout the brewing process. There are also many benefits to using on-site nitrogen generators for beer brewing, these include that less production time is wasted, less gas is wasted, and lower costs are involved.
Less time wasted
If you have access to your own nitrogen on-site you can save a considerable amount of time during production. Breweries that rely on third-party suppliers for nitrogen can risk delays and even cancelled orders – this then risks having to halt production which could result in an eventual loss of profits. Having your own reliable supply of nitrogen on-site will ensure that you can stay focused on the job at hand, and will ensure that beer production isn’t halted.
Less gas waste
For breweries without an on-site nitrogen generator, the only other option is to order in nitrogen in bulk supply. The downside of bulk supply is that the nitrogen won’t be used at once meaning the remaining nitrogen will sit in the tank unused, and may then expand. To avoid nitrogen expanding and the tank exploding from built-up pressure, some gas must be released from the tank. This will then result in wasted nitrogen, and money.
Having an industrial nitrogen generator on-site is significantly cheaper than ordering in bulk supplies of nitrogen. While the upfront cost of on-site nitrogen generation may seem expensive to begin with, the money that the brewery will save in the long run will more than make up for the initial cost. Most breweries can expect to see a return on their investment between 18 to 24 months after startup, depending on the amount of nitrogen they use and the cost they paid for the generator.
Reduce your carbon footprint
Carbon dioxide is frequently used to transfer products between vessels. Switching to nitrogen from carbon dioxide is cost-effective as it will help to reduce gas requirements by up to 70%. This is quite a significant benefit as many businesses are looking at ways in which they can reduce their environmental footprint – using nitrogen instead will help to do just that.
