Types of Industrial Fermentation Tanks
An industrial fermentation tank is a large vessel used to facilitate the process of fermentation in various industrial applications, such as food and beverage, pharmaceuticals, and chemicals. There are several types and designs of large-scale fermentation vessels, including rectangular fermenters, beer fermenters, and stainless steel fermenters.
- Rectangular fermenter: The bioreactor fermenter is typically made up of an upper compartment (fermentation tank) and a lower drain or storage compartment (claimer) placed at an angle that allows the final product to exit. This vessel is commonly used in the production of herbal products, lactic acid, organic matter, and amino acids, among others. It comprises an inner tank, outer tank, and roof exhaust.
- Beer fermenter: Beer fermenters are cylindrical tanks constructed from stainless steel or fiberglass, located in breweries. They provide the ideal settings for yeast to thrive and complete its job of turning sugar into alcohol and carbon dioxide, producing beer in the process. Hence, they are also referred to as brewery fermenters.
- Stainless steel fermenter: The stainless steel fermenter is the main piece of equipment for fermentation and storage. It is fully controlled under the microscope and with no complications. After the fermentation process is finished, the flax tanks are usually taken care of in the bottling or kegging unit.
