How does an industrial candle filter work?
A candle filter can be used for thickening during the production of concentrated slurry or in the clarification of beer. An industrial candle filter operates in short consecutive batches to achieve the desired results. The filtration process begins with precoating to mix filter air into the cake. Once the slurry enters the vessel from the bottom, it compresses air or gas above the candles, increasing the pressure and forcing the filtrate through the filter media. The solids collected on the filter media form a cake displaced downwards by the gas blown into the vessel. The cake in the candle stack undergoes further drying as air passes through it. When the air pressure is released, the cake outlet opens, releasing dried cake. Any slurry that remains in the vessel is washed off.
What are the benefits of different candle filter types?
A candle filter is a versatile piece of industrial equipment used for various applications. Its elements can be adapted to match different industrial processes. For instance, the vessels usually have conical bottoms for polishing applications, which assists with cake discharge. However, industrial candle filters used for thickening have flat bottoms. The candles provide excellent filter elements, and the stainless-steel woven wire mesh supports the filter media. The stainless-steel mesh can withstand the pressure used to remove moisture and release the cake. Due to the materials used to make the fabric media (nylon or Teflon), the filters allow filtration of 1 to 900 microns and higher flow rates. The filter effectively removes concentrated moisture and enhances water or beer purification.
