Why is your fermenter experiencing deformation?

A deformation of the fermentation tank results in downtime for your business. It is important to understand these critical mistakes and how to avoid them in order to save time and money for your brewery.

Improper CIP Timing and Condensation

If cold media is introduced into the fermenter immediately after hot media, the fermentation tank may implode if it is not given enough time to cool down and if proper ventilation is not provided to control condensation. Ventilation allows air to enter the fermentation tank, compensating for the volume change that occurs during steam condensation.

Overflow Entering the Ventilation System

Your ventilation system should not be used to store overflow or determine when your tank is full. When your beer tank is shut off with overflow in the system, the excess product needs to be removed from the ventilation. This process may also remove air from inside the beer fermentation tank, causing the tank to deform. If too much air is removed, the tank will implode.

Inadequate Venting

The size of your vent and filter must allow for an airflow rate that is equal to your tank fill rate. A clogged or closed vent is considered inadequate as it does not provide sufficient venting, resulting in limited airflow into the fermentation tank. When the two rates are unequal, implosions are not the only threat; there is also a risk of loss of sterility.

Equipment Failure

Your equipment can fail if it is not properly operated and maintained. This can lead to all three of the causes mentioned above or trigger a chain reaction of malfunctions if the original issue is not identified and resolved promptly.
