PEKEL

FERMENTATION MADE SIMPLE

Pekel is a canister used for fermenting foods, anything from coleslaw and kimchi, to carrots and beans. The two main innovations of Pekel are the Auto-Burp Cap and the Date Ring. Conventionally, mason jars are used for fermentation. As the food ferments, CO2 is released into the jar and must be let out once a day. This is called 'burping'. If the mason jar is left for more than two days without being burped, the glass jar may explode due to pressure buildup, wasting food and causing possible damage to nearby jars. The Auto-Burp cap features a single direction, self-actuating air valve. This valve can keep Oxygen out preventing mold to grow, yet allows CO2 to escape, preventing the jar from exploding. The revolving Date Ring allows the user to mark the month and day of the beginning of their fermentation project.  

Most jars used for fermentation have a snap-closure such as clasps, locks or latches to keep the lid secured, and the jar airtight. This is needed because pressure buildup can pop the lid off of the jar. If that occurs, the invasion of Oxygen would invite unwelcome bacteria and spoil the fermenting food. Furthermore, brine weights to make sure foods stay submerged under the brine, avoiding contact with the air inside the jar. These weights could be a glass block, stones, or a smaller jar. 
Therefore, an important design decision was made, to implement a twist-cap that also featured an attached blockade. The twist-cap would make sure the lid does not pop off, and the blockade would keep the foods submerged.
