What are tower silos and how do they work?
Tower silos are upright structures used to store and preserve feed, typically for livestock. They work by creating a controlled environment that is ideal for fermenting and storing silage, a type of feed made from fermented plant material. This controlled environment is achieved through the silo’s design, which allows for minimal air entry and maintains a consistent temperature and moisture level, promoting optimal fermentation.
The silage is loaded into the silo through a top hatch, and then compressed to remove any air pockets. As the silage ferments, it releases carbon dioxide, which is allowed to escape through a small opening at the top of the silo. This process creates a vacuum that helps to prevent spoilage and maintains the silage’s nutritional value. The result is a high-quality, nutritious feed that can be used throughout the year.
