Beer Unitank and Brite Beer Tank are two types of vessels commonly used in the brewing industry for beer production and storage. Here's a comparison between the two:
Function:
Beer Unitank: A unitank, also known as a fermenter, is primarily used for the fermentation of beer. It provides an environment for the yeast to convert sugars into alcohol and carbon dioxide. Unitanks are typically equipped with cooling jackets to control the temperature during fermentation.
Brite Beer Tank: A brite beer tank, also called a bright beer tank or a conditioning tank, is used for the storage and carbonation of beer after fermentation. It allows the beer to clarify and mature, while any remaining yeast and sediment settle out. Brite beer tanks are typically pressure-rated and often equipped with carbonation capabilities.
Purpose:
Beer Unitank: The primary purpose of a unitank is to facilitate the fermentation process. It provides the necessary conditions for yeast to ferment the beer and produce alcohol and carbon dioxide. Unitanks are typically used for primary fermentation, where the majority of fermentation takes place.
Brite Beer Tank: The main purpose of a brite beer tank is to store, clarify, and carbonate the beer after fermentation. It allows any remaining sediment to settle, resulting in a clear and bright beer. Brite beer tanks are commonly used for secondary fermentation or conditioning.
Pressure:
Beer Unitank: Unitanks are often designed to handle higher pressures since they need to withstand the pressure generated during active fermentation. They are built to handle the release of carbon dioxide produced by the yeast.
Brite Beer Tank: Brite beer tanks are also pressure-rated but generally operate at lower pressures compared to unitanks. The pressure in a brite beer tank is typically controlled and maintained at a level suitable for carbonation and storage.
Carbonation:
Beer Unitank: Unitanks can be used for carbonation, but it is less common. Carbonation in unitanks is typically achieved by adding a carbonation stone or spunding valve to introduce carbon dioxide during or towards the end of fermentation.
Brite Beer Tank: Brite beer tanks are specifically designed for carbonation. They have carbonation stones or other means of introducing carbon dioxide into the beer. Carbonation is typically achieved by pressurizing the tank with carbon dioxide over a period of time.
Clarity and Conditioning:
Beer Unitank: Unitanks are not primarily designed for achieving optimal clarity or conditioning. Although some clarification may occur during fermentation, the beer may still contain sediment and yeast.
Brite Beer Tank: Brite beer tanks are designed to promote clarity and conditioning. As the beer settles and ages in the tank, remaining yeast and sediment settle to the bottom, resulting in a clearer beer.
In summary, beer unitanks are primarily used for fermentation, while brite beer tanks are utilized for storage, carbonation, and conditioning of the beer after fermentation. Unitanks focus on the fermentation process, while brite beer tanks prioritize the quality, clarity, and carbonation of the final product.
