How to prevent contaminated beer

How can the beer go bad? Bacteria is the biggest killer for beer brewing.All beer brewing equipment including tanks, pipes, heat exchanger etc should not have dead corner which may hide the bacteria in. A small tips to avoid bateria in heat exchanger share with you as below.

The most common form of contamination is bacteria, which grow faster than yeast. The most common cause of contamination is pediococcus or lactobacillus bacteria. Some people are worried about wild yeast. They exist, but their growth rates are slower than bacteria. So concentrate on bacteria. They will give you sauerkraut and cheese smells.
The most common reason bacteria develops is because lines are not clean. The heat exchanger has the greatest potential for harboring bacteria. We rinse our heat exchanger with 180° F water for half an hour. That will kill everything. Either use heat or chlorine (bleach). I use heat because we already have hot water in the brewhouse that we use to mash in with and sparge with. And of course, we make sure hoses and fittings are sanitary.

Strict cleaning precedure is very important for all breweries. Each step must be done well. Or a small mistake may destroy all your beer.
