Advantages of wedge wire candle filter
Wedge Wire Candle Filter
– Providing a larger surface area allows for faster filtration and uses fewer filter aids, which can trap most large particles such as yeast and other impurities.
– The candle filtration surface grows with growing amounts of the floated kieselguhr and captured impurities resulted in a prolonged filtration cycle and increased volumes of filtered beer.
– It can be washed repeatedly.
– The highest filtration accuracy is 10 microns.
– No moving parts.
Metal weave wire mesh filter
The increase or change in the filtration flow rate or pressure will cause the screen (a fabric made of fine metal wire) to deform, the diatomite filter layer also deforms.
Diatomaceous earth can leak and cause impurities to mix into the filtrate.
Wedge wire screen candle filter
The solid steel cylindrical slotted screen filter can prevent the filter layer from deforming under normal circumstances. The stable filter layer is more efficient in capturing impurities.
The V-shaped wire screen filter can even finely filter beer (the highest precision of BLUSLOT can reach 10 microns).
Filtration is one of the key processes in brewery operations. Technical requirements include the need for a bright, shiny filtrate with optimal turbidity and improved beer physical stability.
Candle filter is a pre-coated or pressure filter, mainly used to clarify the fermented and stored beer.
The name is taken from the shape of the filter element, which is an elongated cylinder, similar to a candle.
In the brewing industry, wedge mesh candle filters were developed for beer filtration in the 1950s and 1960s. It is still popular today.
The wedge wire candle filter element is installed in a cylindrical pressure vessel that receives unfiltered beer.
The wedge wire candle filter element itself is the membrane containing the filter aid. During the solid-liquid separation process, the filter aid may be diatomaceous earth, perlite, cellulose, or other materials, the candle does not perform any filtering.
Covering the candle is a filter aid, which can perform the actual filtration.
Today, candles are made of stainless steel V-shaped wedge wire, and their accuracy is much higher than that of the old-style candles.
Unfiltered beer passes through the filter cake from the outside of the candle and enters the center of the wedge wire candle filter. The filtered beer now flows out of the filter housing through the mounting plate or manifold that holds the candle filter.
The most candle filter element is installed on the top of the filter housing, but some models of candle filters are installed on the bottom.
