When it comes to brewing beer, filtration plays a crucial role in achieving clarity and purity. Two common types of filtration systems used in breweries are the hop filter and the diatomite filter. Each serves a distinct purpose in the brewing process, contributing to the quality and taste of the final product.
Hop Filter: Enhancing Wort Clarity
The hop filter, positioned before the plate heat exchanger, primarily focuses on clarifying the wort. As the wort passes through the hop filter or hop filter tank, it undergoes initial filtration to remove hop particles and other sediments. This clear wort then proceeds to the plate heat exchanger for cooling, a critical step before fermentation in the fermenter begins.
Diatomite Filter: Refining Mature Beer
In contrast, the diatomite filter is employed post-brewing to filter mature beer. This type of filtration system is more intricate, typically consisting of a candle-type diatomite filter host, a pipeline system, and an electrical control setup. The main filter tank of the diatomite filter includes a filtrate chamber and a candle wick mounting plate.
Components of a Candle-Type Diatomite Filter
The candle wicks, fixed on the mounting plate, play a pivotal role. They are equipped with special flanges to ensure efficient filtration. As the beer to be filtered enters the tank, it mixes with diatomaceous earth, a filter aid that helps in trapping yeast and solid particles. The cylindrical cone bottom of the tank facilitates the collection and discharge of diatomite slurry during cleaning and aids in distributing suspensions during pre-coating and filtration.
Operational Efficiency
A crucial feature of the diatomite filter is its ability to uniformly pre-coat or add filter aids onto each candle wick, ensuring consistent and effective filtration. Under pressure, the liquor is sieved, retained, and adsorbed by the diatomaceous earth, resulting in clear, refined beer ready for consumption.
Choosing the Right Equipment for Your Brewery
Whether you’re starting a new brewery or expanding an existing one, selecting the appropriate filtration equipment is paramount.
